Conventional computer-based CD players resemble traditional physical CD players. This is fine, if your user interface consists of 10 buttons. However, computers have keyboards, so why not use them? Besides, it's certainly a waste of a console or an xterm to have a traditional CD player open anyway. cdcd works in two ways, accepting commands directly off the command line or in a query mode similar to other UNIX programs. To pass a command to cdcd, simply run cdcd with the command as the arguement (e.g. cdcd play). This is great for using cron and cdcd together to make a CD alarm clock. Or, you can run cdcd without arguments and you will be given the cdcd command prompt. For information regarding cdcd and new releases, visit http://libcdaudio.sourceforge.net/ . Installation ------------ For help with installation, please see the file INSTALL. Usage ----- Preliminary note: this file is less often updated than the source files, so you may see some changes between the outputs shown here and the outputs you get. After cdcd is installed, type 'cdcd'. You should receive a prompt like this: cdcd x.x.x, Copyright (C)1998-99 Tony Arcieri, 2001 Fabrice Bauzac Distributed under the GNU General Public License. See file COPYING for details. Using libcdaudio x.x.x Enter ? for help. cdcd> Enter a command, for example, help: cdcd> help Available commands: !, ?, access, close, debug, device, edit, eject, exit, ext, ff, getvol, help, info, list, next, open, pause, play, prev, quit, refresh, resume, rew, rndplay, setvol, sites, slot, status, stop, submit, tracks, verbose, and version. For more specific help, type `help '. cdcd> As you can see, the command will perform its function, and then return you to the command prompt. You can receive help on specific items by passing an argument to the help function: cdcd> help play Usage: play [starttrackname/track #] [endtrackname/track #] [min:sec] By default, starts at the beginning of the CD. You may specify tracks using either the number of the track or a section of the track's name. The disc will play from where it starts to the end of the disc or a track you specify. You may also specify a position within the first track to start. cdcd> By default, play starts at the beginning of the CD. You may specify tracks using either the number of the track or a section of the track's name. The disc will play from where it starts to the end of the disc or a track you specify. You may also specify a position within the first track to start. To play a CD, you can simply type 'play', or if you prefer, 'play ', or 'play track#.' You may also specify a track at which to end play, and also a time within the track to start. Here are a few examples: cdcd> play 5 This would play track #5 and stop at the end of the disc. cdcd> play Time This would play the first song on the disc with "Time" as a part of its name and stop at the end of the disc. cdcd> play Time 5 This would play the first song on the disc with "Time" as part of its name and stop at track #5. cdcd> play Time 3:30 This would play the first song on the disc with "Time" as part of its name and start 3 minutes and 30 seconds into the song and stop at the end of the disc. cdcd> play 3 5 3:30 This would play from track 3 to track 5 and start 3:30 into track 3. cdcd> play 3 "Us and Them" 5: This would play from track 3 to the first song on the disc with "Us and Them" as part of its title and start 5:00 into track 3. cdcd> play 5 5 This would play track 5 and stop at the end of track 5; an easy way to play only a single track. cdcd> play 3:30 This would set the postition within the current song to 3:30. Some commands put you into a cdcd subshell. For example, type: cdcd> sites cdcd/sites> Then you can ask for some help to see the available commands: cdcd/sites> ? Available commands: .., ?, add, del, display, exit, help, move, quit, and refresh. For more specific help, type `help '. cdcd/sites> You can use the special command `..' to return one level up in the shells hierarchy. cdcd/sites> .. cdcd> If you are in interactive mode and are finished, simply type `quit' and RETURN, or C-d (^D, Control + D). The CD will continue playing: cdcd> quit $ You can also pass commands to cdcd right off the command line: $ cdcd info Album name: The Dark Side Of The Moon Album artist: Pink Floyd Total tracks: 9 Disc playing: 07:37 of 42:59 Playing: Time 03 00:01 of 07:05 $ CDDB Interface -------------- As of libcdaudio-0.4.2 (and cdcd-0.3.2), cdcd supports the CD Database system, which allows retrieval of CD information off of the Internet. The CDDB interface is on by default. Whenever a command is invoked that uses CD database information (e.g. play, ext, info, infoall) libcdaudio will search in the local cache (located under ~/.cddb) first, and if it is unable to locate information for the current CD, it will connect to a CDDB server and attempt to retrieve it. If this is the first time you've used a particular CD with cdcd, you may notice a 5-10 second delay with the previously mentioned commands. This is because cdcd is connecting to the CDDB server and retrieving disc information. As soon as this has been completed, the command will no longer block, and you will be given the shell prompt or cdcd command prompt again. Perhaps you don't like automated CDDB operation. You can enable or disable verbose, manual CDDB operation using the verbose command: cdcd> verbose on cdcd> From now on, any command that uses the CDDB code will tell you exactly what it is doing: cdcd> info Trying cddbp://www.cddb.com:8880/ Connection established. Retrieving information on 770f0d19. Inexact match for 770f0d19. Please choose from the following inexact matches: 1: The Beach Boys / Made In U.S.A. 2: None of the above. > 1 Downloading data... Album name: Made In U.S.A. Album artist: The Beach Boys Total tracks: 25 Disc length: 64:15 Stopped cdcd> Of course, all of that will only happen the first time you use the disc with cdcd. Normally the CDDB information will simply stay cached in ~/.cddb. As of libcdaudio-0.4.3, a caching system compatible with XFreeCD and other CD players is used. This allows you to read CD information from discs played using these other players. As of libcdaudio-0.4.4, extended information is supported. In cdcd, you can display extended information (if it is available) using the ext command. CD-ROM Changer Support ---------------------- Linux 2.1 and 2.2 users with CD-ROM changers may take advantage of the CD-ROM changer functions within cdcd. To use your CD-ROM changer with cdcd, there are only two functions you must know, list and seldisc: cdcd> list Disc 1: 42:59 Pink Floyd / The Dark Side of the Moon Disc 2: 44:28 Pink Floyd / Wish You Were Here Disc 3: 42:39 Led Zeppelin / IV cdcd> The list command displays the contents of your CD-ROM changer. To choose a particular disc from the CD-ROM changer, use the slot command: cdcd> slot 1 Controlling CDDB Operation -------------------------- As of libcdaudio 0.6.1, cdcd uses a radically different CDDB interface. If you previously generated a ~/.cddbrc you should delete it. All CDDB operations use specific URLs for the server. To use the CDDB server cddb.cddb.com that operates on port 8880, you should use the following URL: cddbp://cddb.cddb.com:8880 If instead, you wished to use the HTTP server www.cddb.com port 80, use: http://www.cddb.com:80/~cddb/cddb.cgi Notice /~cddb/cddb.cgi on the end. This is the path to the actual CDDB CGI, and must be used with any HTTP URL. To automatically update the CDDB server list, use the 'sites/refresh' command. Any further CDDB operations will pull entries from this list. If the first server fails, it will automatically go on to the next one, until it has exhausted the whole list. Tuning Readline --------------- You can easily add shortcuts for usual commands, by tweaking your ~/.inputrc file. Here is an example: ~/.inputrc: ----- $if cdcd "\e[[A": "open\n" # F1 will open the CD tray "\e[[B": "close\n" "\e[[C": "play\n" "\e[[D": "prev\n" "\e[[E": "next\n" "\C-xw": "prev\n" # C-x w will select the previous track "\C-xx": "play\n" "\C-xc": "pause\n" "\C-xC": "resume\n" "\C-xv": "stop\n" "\C-xb": "next\n" $endif ----- Remember: to type C-x w, hold down Control, then type x once, then release the Control key, and type w once. Bugs ---- All bug reports should be sent to noon@users.sourceforge.net. cdcd has been tested under many versions of Linux, and FreeBSD 3.0. If you do experience problems either compiling or while operating cdcd, please send the following: * The version of cdcd you are using. * The version of libcdaudio you are using. * Your platform type and release. * A complete list of errors that occurred either during the compile (make >& errors) or a detailed description of what happened while cdcd was in operation. * Any other information you believe is relevant. Patches ------- If you think you can do something better than the existing code, by all means, send me the patch! Send all patches to noon@users.sourceforge.net. Be sure to include your name so I can credit your code. If the patch fixes a bug, it would be nice if you send the patch along with the bug report.

The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary.

Note: If your system have a packaging system (rpm, deb, etc.), it is suggested that you use a cdcd package, in order to keep your system cleaner. If there is no package corresponding to the latest version of cdcd, then you can (politely) ask the cdcd package maintainer to make it. But the maintainers are, in general, volunteers: don't assume they will work as soon as you ask. This package is designed to be built with libcdaudio 0.99.1 or later. Previous versions of libcdaudio could work, but it is advised to upgrade. libcdaudio must be obtained seperately. If you have not already downloaded it you may get it from the following location: http://libcdaudio.sourceforge.net/ The latest version of libcdaudio, at the time of this writing, is 0.99.5. You will need the Readline library, version 4.2 or higher, too. ================================================================ IMPORTANT NOTE ABOUT LIBRARIES: On the GNU/Linux system, and in some others, when a library is put on the filesystem, the dynamic loader must be told about that in order to make use of the library. If there is a file /etc/ld.so.conf, then it is the case. Telling the new libraries information to the dynamic loader (ld) is done in two steps (the root rights are usually required, so use "su"): 1. add the directory where the library resides in the /etc/ld.so.conf file (e.g. /usr/local/lib), if it is not already there. 2. run ldconfig with no arguments. ================================================================ Here are the steps required to install cdcd. Step 1. Run the configuration script. This script will configure the build for your compiler. Simply run: ./configure For systems using a different shell than bash or sh (e.g. csh), you will need to run: sh ./configure Be sure to watch the output from configure for anything abnormal. Step 2. Run `make'. This will build cdcd. Step 3. Run `make install' as the super-user. This will install cdcd under /usr/local/bin. Make sure /usr/local/bin is in your PATH before running cdcd. Step 4. (optional) Run `make clean'. This will remove all object and binary files, leaving the source. If you have no need for the source, you may simply delete it. Note that you have to keep the source to be able to do a `make uninstall'. That should do it. You should be able to run cdcd just fine now. cdcd-0.6.6/NEWS0000644000175000017500000000563010006571655010051 00000000000000Changes in 0.6.6: * Remove some dependencies (if vasprintf isn't there, try to use vsnprintf to emulate it, before asking for GLib). * Get the actual terminal width for comfortable display. Changes in 0.6.5: * Bugfix release. Changes in 0.6.4: * The "toggle" command now starts playing the CD if it is stopped. * On systems which do not provide a `vasprintf' (Solaris 8, for example), cdcd will work (the incompatibility was introduced in a previous version of cdcd). But you will need Glib 1.1.12 or higher. * Bug fixes in the configure script. Changes in 0.6.3: * Fixed a bug in the manual configuration. Changes in 0.6.2: * Check for .cdcdrc's readability (thanks to Matt Kraai). * Some fixes. Changes in 0.6.1: * Bugfix release. * Jump: 0.5.6 -> 0.6.1, in order to prevent the confusion that cdcd 0.6.0 is newer than 0.5.* Changes in 0.5.6: * New `toggle' command (thanks to Mickael Fair). * Texinfo documentation. Changes in 0.5.5: * Bugfix release. Changes in 0.5.4: * The `play' command's behaviour is more slow-connection friendly: play first, then CDDB/CDIndex-lookup (whenever possible). Changes in 0.5.3: * cdcd now accepts commandline switches (--version, --help, --device). Changes in 0.5.2: * Fixed Makefile.am and conf.c (thanks to ) Changes in 0.5.1: * Better readline+history support. * Cosmetic changes. * Subshells system introduced. * The `tracks' command now shows which track we are playing. * A `!' command to execute things from inside your cdcd. * Some fixes. Changes in 0.5.0: * cdcd now uses the 1.0 version of the libcdaudio API * Configuration questionaire pops up to aid cdcd setup. Changes in 0.4.6: * Command and track name completion. Just use 'tab'. Changes in 0.4.5: * cdcd now has CD Index support and will use CD Index servers by default * cdcd has a manpage, finally Changes in 0.4.4: * Fixed for new libcdaudio interface * Fixed glibc2.1 related bugs Changes in 0.4.3: * Bugs in autoconf fixed * 'submit' feature added * 'sites' feature expanded * 'infoall' removed in favour of 'tracks' * 'seldisc' removed in favour of 'slot' Changes in 0.4.1: * Multiple bugs fixed in the code * setpos was eliminated as a redundant feature (play serves the same function) Changes in 0.3.11: * Multiple bugs fixed in the code Changes in 0.3.10: * Added client/server CDDB toggle command, cddbmsg. * Interface modified to fit new libcdaudio database interface * Device selection support Changes in 0.3.9: * Fixed memory leak in strnupper * Improved ff, rew, and edit commands Changes in 0.3.8: * Multiple arguements implemented * Play function improved Changes in 0.3.7: * volume control functions changed to getvol/setvol * CD changer support implemented * debug command added * Better info/infoall commands * Genre editing supported with edit command Changes in 0.3.6: * Makefile now generated with automake/autoconf * CDDB support, and support extended data cdcd-0.6.6/ansi2knr.10000644000175000017500000000277107301176335011166 00000000000000.TH ANSI2KNR 1 "19 Jan 1996" .SH NAME ansi2knr \- convert ANSI C to Kernighan & Ritchie C .SH SYNOPSIS .I ansi2knr [--varargs] input_file [output_file] .SH DESCRIPTION If no output_file is supplied, output goes to stdout. .br There are no error messages. .sp .I ansi2knr recognizes function definitions by seeing a non-keyword identifier at the left margin, followed by a left parenthesis, with a right parenthesis as the last character on the line, and with a left brace as the first token on the following line (ignoring possible intervening comments). It will recognize a multi-line header provided that no intervening line ends with a left or right brace or a semicolon. These algorithms ignore whitespace and comments, except that the function name must be the first thing on the line. .sp The following constructs will confuse it: .br - Any other construct that starts at the left margin and follows the above syntax (such as a macro or function call). .br - Some macros that tinker with the syntax of the function header. .sp The --varargs switch is obsolete, and is recognized only for backwards compatibility. The present version of .I ansi2knr will always attempt to convert a ... argument to va_alist and va_dcl. .SH AUTHOR L. Peter Deutsch wrote the original ansi2knr and continues to maintain the current version; most of the code in the current version is his work. ansi2knr also includes contributions by Francois Pinard and Jim Avera . cdcd-0.6.6/ansi2knr.c0000644000175000017500000004142407641631757011261 00000000000000/* Copyright (C) 1989, 1997, 1998 Aladdin Enterprises.

This mode of operation is selected by either setting the environment variable POSIXLY_CORRECT, or using `+' as the first character of the list of option characters. PERMUTE is the default. We permute the contents of ARGV as we scan, so that eventually all the non-options are at the end. This allows options to be given in any order, even with programs that were not written to expect this. RETURN_IN_ORDER is an option available to programs that were written to expect options and other ARGV-elements in any order and that care about the ordering of the two. We describe each non-option ARGV-element as if it were the argument of an option with character code 1. Using `-' as the first character of the list of option characters selects this mode of operation. The special argument `--' forces an end of option-scanning regardless of the value of `ordering'.

If `getopt' is called repeatedly, it returns successively each of the option characters from each of the option elements. If `getopt' finds another option character, it returns that character, updating `optind' and `nextchar' so that the next call to `getopt' can resume the scan with the following option character or ARGV-element. If there are no more option characters, `getopt' returns `EOF'. Then `optind' is the index in ARGV of the first ARGV-element that is not an option. (The ARGV-elements have been permuted so that those that are not options now come last.) OPTSTRING is a string containing the legitimate option characters. If an option character is seen that is not listed in OPTSTRING, return '?' after printing an error message. If you set `opterr' to zero, the error message is suppressed but we still return '?'. If a char in OPTSTRING is followed by a colon, that means it wants an arg, so the following text in the same ARGV-element, or the text of the following ARGV-element, is returned in `optarg'. Two colons mean an option that wants an optional arg; if there is text in the current ARGV-element, it is returned in `optarg', otherwise `optarg' is set to zero. If OPTSTRING starts with `-' or `+', it requests different methods of handling the non-option ARGV-elements. See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. Long-named options begin with `--' instead of `-'. Their names may be abbreviated as long as the abbreviation is unique or is an exact match for some defined option. If they have an argument, it follows the option name in the same ARGV-element, separated from the option name by a `=', or else the in next ARGV-element. When `getopt' finds a long-named option, it returns 0 if that option's `flag' field is nonzero, the value of the option's `val' field if the `flag' field is zero. The elements of ARGV aren't really const, because we permute them. But we pretend they're const in the prototype to be compatible with other systems. LONGOPTS is a vector of `struct option' terminated by an element containing a name which is zero. LONGIND returns the index in LONGOPT of the long-named option found.

Q. Johnson of Cornell. J.Otto Tennant contributed the Cray support. There are some preprocessor constants that can be defined when compiling for your specific system, for improved efficiency; however, the defaults should be okay. The general concept of this implementation is to keep track of all alloca-allocated blocks, and reclaim any that are found to be deeper in the stack than the current invocation. This heuristic does not reclaim storage as soon as it becomes invalid, but it will do so eventually. As a special case, alloca(0) reclaims storage without allocating any. It is a good idea to use alloca(0) in your main control loop, etc. to force garbage collection. */ #ifdef HAVE_CONFIG_H #include "config.h" #if defined (HAVE_STDLIB_H) # include #elif defined (HAVE_MALLOC_H) # include #endif #endif /* If compiling with GCC, this file's not needed. */ #ifndef alloca #ifdef emacs #ifdef static /* actually, only want this if static is defined as "" -- this is for usg, in which emacs must undefine static in order to make unexec workable */ #ifndef STACK_DIRECTION you lose-- must know STACK_DIRECTION at compile - time #endif /* STACK_DIRECTION undefined */ #endif /* static */ #endif /* emacs */ /* If your stack is a linked list of frames, you have to provide an "address metric" ADDRESS_FUNCTION macro. */ #ifdef CRAY long i00afunc (); #define ADDRESS_FUNCTION(arg) (char *) i00afunc (&(arg)) #else #define ADDRESS_FUNCTION(arg) &(arg) #endif #if __STDC__ typedef void *pointer; #else typedef char *pointer; #endif #ifndef NULL #define NULL 0 #endif /* Define STACK_DIRECTION if you know the direction of stack growth for your system; otherwise it will be automatically deduced at run-time.

Invoking cdcd without a command will cause cdcd to enter query mode. Invoking cdcd with a command will cause cdcd to execute that command and then terminate when it is finished. .SH OPTIONS .TP .BI \-\-device " DEVICE" .TP .BI \-d " DEVICE" Use .I DEVICE as the CD device. .I DEVICE is the device special file name of the CD-ROM device. Do not use a Linux SCSI Generic device. .SH USAGE The following are the supported commands: .TP \fBplay\fR [\fBstart track\fR] [\fBend track\fR] [\fBmin\fR:\fBsec\fR] If \fBstart track\fR is specified, play will play the specified track instead of the first track. If \fBend track\fR is specified, the disc will be played from the start track to the end track. \fBstart track\fR and \fBend track\fR may either be part of or an entire track title. If a starting position is specified (in the form \fBmin\fR:\fBsec\fR), then the disc will begin playing the specified amount of time into the specified track. One may specify a starting position without specifying a \fBstart track\fR or only specify a \fBstart track\fR and starting position while specifying no \fBend track\fR .TP .B stop This will stop the CD if it is playing. .TP \fBopen\fR, \fBeject\fR This will eject the CD-ROM tray .TP .B close This will close the CD-ROM tray .TP .B pause This will pause the CD if it is playing .TP .B resume This will cause a paused CD to resume playing .TP \fBff\fR [\fBmin\fR:\fBsec\fR] This will fast-forward the CD 15 seconds by default, or the specified amount of time .TP \fBrew\fR [\fBmin\fR:\fBsec\fR] This will rewind the CD 15 seconds by default, or the specified amount of time .TP .B next This will advance the CD one track .TP .B prev This will return the CD to the previous track .TP .B getvol This will return the current volume settings .TP \fBsetvol\fR [\fBleft front\fR] [\fBright front\fR] [\fBleft rear\fR] [\fBright rear\fR] Sets the CD-ROM volume to the given settings. Most CD players only support the front two channels .TP .B status Gives only numerical data regarding the CD's status .TP .B info Gives disc name, artist, current track name, and disc positions .TP .B tracks Lists all tracks on the CD and their lengths .TP .B rndplay Plays a random track .TP .B list Lists all CDs in a CD-ROM changer .TP .B slot Changes the current CD in the CD-ROM changer .TP \fBedit\fR [\fBname\fR, \fBartist\fR, \fBgenre\fR, \fBtrack no.\fR] [\fBvalue\fR] Edits information about the disc. You may specify \fBname\fR, \fBartist\fR, \fBgenre\fR, or the number of the track you wish to edit .TP \fBext\fR [\fBtrack no.\fR, \fBdisc\fR] This will display extended information about the disc. If no parameter is given it will display information about the current track. Specifying \fBdisc\fR will display information for the disc itself .TP .B refresh This will connect to a server and retrieve information about the CD even if there already exists information about it. Otherwise, this is done automatically by any command that uses disc/track names .TP \fBdevice\fR [\fBdevice name\fR] This sets the CD-ROM device cdcd will use in future invocations which don't specify the -d option. .B cdcd stores this information in your .I .cdcdrc file. .TP \fBverbose\fR [\fBon\fR, \fBoff\fR] This toggles whether cdcd will display everything that is happening (e.g. when accessing a CDDB or CD Index server) .TP .B quit Exits cdcd .TP \fBsites\fR [\fBrefresh\fR, \fBdisplay\fR, \fBadd\fR, \fBdelete\fR, \fBmove\fR] This edits the server list. More specific help on each of the commands is available by typing \fBcdcd help sites\fR .TP \fBsubmit\fR [\fBe-mail address\fR] This will submit a CDDB entry to a CDDB server .TP \fBaccess\fR [\fBlocal\fR, \fBremote\fR, \fBproxy\fR] Specifying \fBlocal\fR will cause CD information requests to return Unknown for track, artist, and album titles, and will not attempt to connect to any servers. \fBremote\fR will cause cdcd to connect to a server whenever any CD information is required. If you need to use a HTTP proxy, it may be specified in the form \fBproxy url\fR, where \fBurl\fR is the URL for your HTTP proxy .SH COMPLETION cdcd uses traditional readline command and trackname completion. To complete a command, simply hit 'tab' when you have typed a partially completed command. To complete a trackname, first type whatever command you wish to pass a track name to (e.g. play, ext) and then begin with a double quotation mark. Type the beginning of the track name and then hit tab. The track name will be completed for you. .PP .RS .nf cdcd> pl cdcd> play "See cdcd> play "See You On The Other Side" .fi .RE .SH REPORTING BUGS Report bugs to cdcd-0.6.6/doc/0000777000175000017500000000000010033650717010174 500000000000000cdcd-0.6.6/doc/gpl.texinfo0000644000175000017500000004365105325364076012311 00000000000000@setfilename gpl.info @unnumbered GNU GENERAL PUBLIC LICENSE @center Version 2, June 1991 @display Copyright @copyright{} 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave, Cambridge, MA 02139, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. @end display @unnumberedsec Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software---to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. @iftex @unnumberedsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION @end iftex @ifinfo @center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION @end ifinfo @enumerate @item This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The ``Program'', below, refers to any such program or work, and a ``work based on the Program'' means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term ``modification''.) Each licensee is addressed as ``you''. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. @item You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. @item You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: @enumerate a @item You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. @item You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. @item If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) @end enumerate These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. @item You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: @enumerate a @item Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, @item Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, @item Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) @end enumerate The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. @item You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. @item You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. @item Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. @item If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. @item If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. @item The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and ``any later version'', you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. @item If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this.

To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the ``copyright'' line and a pointer to where the full notice is found. @smallexample @var{one line to give the program's name and an idea of what it does.} Copyright (C) 19@var{yy} @var{name of author} This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

It permits you to control your CD drive(s) from any shell prompt, or from Cdcd's own Readline prompt with command and track completion. It can retrieve the information about an audio CD's track names and artist(s) from any @acronym{CDDB}- or @acronym{CDIndex}-compatible database server. Cdcd needs the Libcdaudio library. The homepage for Cdcd and Libcdaudio is currently at @url{http://libcdaudio.sourceforge.net/}. Cdcd was originally written by Antony Arcieri. Fabrice Bauzac modified it and is the current maintainer. @node Getting Started, Invocation, Introduction, Top @chapter Getting Started @cindex getting started The Cdcd program works in two ways: either in the non-interactive interface from the command-line, or interactively, from the Cdcd prompt. This chapter documents a subset of the non-interactive interface, to get started. The general non-interactive syntax for @command{cdcd} is: @example cdcd @var{command} @var{arguments...} @end example @section The @code{play} command @cindex @code{play} command overview You can play the current track of an audio CD with this command: @example cdcd play @end example The current track is a variable contained into your CD drive; it is generally the first track (1). To play a specific track, type @example cdcd play @var{tracknum} @end example Replace @var{tracknum} with the track number you want to play. The CD drive will keep playing tracks until it reaches a non-audio track or the last track. If you know a part of the title of the track you want to play, you can type @example cdcd play @var{part} @end example For example, you may type @code{cdcd play free} to play the Free Software Song, sung by Richard Stallman. @section Other useful commands @cindex overview of commands @cindex commands, overview Other useful commands include: @table @samp @item stop Stop playing. @item pause @itemx resume Pause, resume a paused song. @item toggle Toggle between pausing/resuming a song. @item open @itemx close Open, close the CD tray. @item next @itemx prev Play the next or previous track. @item tracks Show information about the current CD. @end table @node Invocation, The Cdcd Prompt, Getting Started, Top @chapter Invocation @cindex invocation @cindex Cdcd invocation @cindex invoking Cdcd @cindex command-line interface @cindex shell, invoking cdcd from the shell Cdcd accepts options and/or commands as arguments. @example cdcd [@var{options...}] [@var{command} [@var{command parameters...}]] @end example If no command is given, it starts the interactive prompt. @menu * Command-line Options:: Classic @acronym{UNIX} options. * General Commands:: Main commands. @end menu @node Command-line Options, General Commands, , Invocation @section Command-line options @cindex options Cdcd accepts three options. @table @samp @item -h @itemx --help Print a summary of the command-line options and commands to Cdcd and exit. @item -v @itemx --version Print the version number of Cdcd and exit. @cindex several drives, commandline option @cindex setting the current drive @cindex device, setting the @item -d @var{device} @itemx --device=@var{device} Use @var{device} as the device name.

A time is in the @code{MM:SS} form, e.g. @code{3:12}, @code{:24}, @code{1:}. @item @cindex @code{stop} You can stop the CD drive from playing, with the @code{stop} command. @item @cindex @code{pause} @cindex @code{resume} @cindex @code{toggle} The @code{pause} and @code{resume} commands can be used to temporarily pause the playing of a CD track, allowing the user to resume the play where it was paused, unlike @code{stop}. The @code{toggle} command switches between pausing and playing the current song. @item @cindex @code{rndplay} The @code{rndplay} command plays a random track. @end itemize @node Moving, Displaying, Playing, General Commands @cindex moving @subsection Moving around @itemize @bullet @item @cindex @code{next} @cindex @code{prev} You can start playing the next or previous track with the @code{next} and @code{prev} commands. @item @cindex @code{ff} @cindex fast forwarding @cindex @code{rew} @cindex rewinding The @code{ff} and @code{rew} commands let you change the playing position within the current track. @example ff [@var{mm}:@var{ss}] rew [@var{mm}:@var{ss}] @end example For example, @samp{ff 3:12} will jump forward by 192 seconds; @samp{rew :12} will jump backward by 12 seconds. The default time to jump is 15 seconds; i.e. @samp{ff} means @samp{ff :15}. @end itemize @node Displaying, Changing CDs, Moving, General Commands @cindex information, displaying @cindex displaying useful information @subsection Displaying Useful Information @itemize @bullet @item @cindex @code{status} The @code{status} command gives bare-bones information about the status of the CD. For more information, use the @code{info} command below. @item @cindex @code{info} The @code{info} command displays statistics about the CD, such as the name, artist, track number, time, etc. @item @cindex @code{tracks} Cdcd will display the album, artist, track length and track titles with the @code{tracks} command. If a track line contains the @samp{>} marker, it means it is the current track. @item @cindex @code{ext} @cindex extended information, obtaining The @code{ext} command gives the extended information of the CD or a track. @example ext ext @var{trackname} ext @var{tracknum} ext disc @end example @end itemize @node Changing CDs, Volume Control, Displaying, General Commands @cindex changing discs @cindex disc, changing @subsection Changing discs @itemize @bullet @item @cindex tray, controlling the @cindex CD tray, controlling the @cindex @code{open} @cindex @code{close} @cindex @code{eject} You can open and close the disc tray with the @code{open}/@code{eject} and @code{close} commands. @item @cindex several drives, command @cindex modifying the current drive @cindex device, changing the The @code{device} command lets you change the device name that Cdcd controls (default @file{/dev/cdrom}). @xref{Command-line Options, The @code{--device} option}, for information about setting the device with a command-line option. @example device @var{device} @end example @end itemize @cindex disc changer commands @cindex changer, commands @cindex multi-disc drive @subsubsection Multi-disc Drives If you own a drive that supports several discs (a cd changer), you can use the following commands to control it. @itemize @bullet @item @cindex @code{slot} The @code{slot} command lets you choose which slot to activate. @example slot @var{disc-number} @end example where @var{disc-number} is the number of the slot you want to activate. @item @cindex @code{list} The @code{list} command will display the entire contents of your changer. @end itemize @emph{Note}: CD changers are not supported on all platforms. @node Volume Control, Other Commands, Changing CDs, General Commands @cindex volume, controlling the drive's @subsection Controlling the Drive's Volume @itemize @bullet @item @cindex @code{setvol} The @code{setvol} command can set the drive's volume. Drives can have from two to four channels. The four channels are: front left (@samp{fl}), front right(@samp{fr}), back left (@samp{bl}) and back right (@samp{br}). Two-channel drives only use the front channels. Each channel volume can be set to a value between 0 and 255 inclusive. @example setvol [@var{volume}] [f=@var{volume}] [b=@var{volume}] [l=@var{volume}] [r=@var{volume}] [fl=@var{volume}] [fr=@var{volume}] [bl=@var{volume}] [br=@var{volume}] @end example @item @cindex @code{getvol} The @code{getvol} command displays the volume settings. @end itemize @strong{Note}: if you listen to your tracks through a mixer-capable device such as a sound card, it is best to leave the drive's volume settings to the default (usually 255), since the drive's mixer is basic and is less easily controlled. The @code{setvol} and @code{getvol} commands are provided only for completeness. Use @file{/dev/mixer} instead. @node Other Commands, , Volume Control, General Commands @subsection Other Commands @itemize @bullet @item @cindex @code{refresh} The @code{refresh} command looks up for the current CD's information in the cd databases online, and updates it. @item @cindex @code{verbose} You can control Cdcd's verbosity with the @code{verbose} command.

The directories are root, @samp{edit}, @samp{access}, and @samp{sites}. The prompt tells you in which directory you are. e.g. @samp{cdcd>} means that you are in the root directory, whereas @samp{cdcd/access>} means you are in the @samp{access} directory. You can change the current directory in two ways. @itemize @bullet @item You can go into one subdirectory typing its name. e.g. if you are in the root directory and want to go to the @samp{sites} subdirectory, type @code{sites}. @item You can go back up one directory typing "@code{..}"; e.g. if you are in the @samp{edit} subdirectory and type "@code{..}", then you'll be in the root directory. @end itemize @cindex @code{help} You can use the @code{help} command to list all of the available commands in the current directory. @code{?} is an alias for @code{help}. You can display information about a particular command with the following syntax: @example help @var{command} @end example Then Cdcd will display the on-line help for the command @var{command}. @node Miscellaneous Root Commands, The Sites Directory, The Directories System, The Cdcd Prompt @cindex directories, root @section Miscellaneous Root Commands Most of the root commands have been already described, in the case of non-interactive use; @xref{General Commands}, for more information.

Preamble ======== The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 1. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 2. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 3. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a. You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b. You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c. If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 4. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a. Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b. Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c. Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 5. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 6. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 7. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 8. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 9. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 10. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 11. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 12. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 13. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs ============================================= If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. ONE LINE TO GIVE THE PROGRAM'S NAME AND AN IDEA OF WHAT IT DOES. Copyright (C) 19YY NAME OF AUTHOR This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19YY NAME OF AUTHOR Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. SIGNATURE OF TY COON, 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License.  File: cdcd.info, Node: Introduction, Next: Getting Started, Prev: Copying, Up: Top Introduction ************ The Cdcd program, or Command-Driven CD player, is a command-line audio CD player. It permits you to control your CD drive(s) from any shell prompt, or from Cdcd's own Readline prompt with command and track completion. It can retrieve the information about an audio CD's track names and artist(s) from any CDDB- or CDIndex-compatible database server. Cdcd needs the Libcdaudio library. The homepage for Cdcd and Libcdaudio is currently at . Cdcd was originally written by Antony Arcieri. Fabrice Bauzac modified it and is the current maintainer.  File: cdcd.info, Node: Getting Started, Next: Invocation, Prev: Introduction, Up: Top Getting Started *************** The Cdcd program works in two ways: either in the non-interactive interface from the command-line, or interactively, from the Cdcd prompt. This chapter documents a subset of the non-interactive interface, to get started. The general non-interactive syntax for `cdcd' is: cdcd COMMAND ARGUMENTS... The `play' command ================== You can play the current track of an audio CD with this command: cdcd play The current track is a variable contained into your CD drive; it is generally the first track (1). To play a specific track, type cdcd play TRACKNUM Replace TRACKNUM with the track number you want to play. The CD drive will keep playing tracks until it reaches a non-audio track or the last track. If you know a part of the title of the track you want to play, you can type cdcd play PART For example, you may type `cdcd play free' to play the Free Software Song, sung by Richard Stallman. Other useful commands ===================== Other useful commands include: `stop' Stop playing. `pause' `resume' Pause, resume a paused song. `toggle' Toggle between pausing/resuming a song. `open' `close' Open, close the CD tray. `next' `prev' Play the next or previous track. `tracks' Show information about the current CD.  File: cdcd.info, Node: Invocation, Next: The Cdcd Prompt, Prev: Getting Started, Up: Top Invocation ********** Cdcd accepts options and/or commands as arguments. cdcd [OPTIONS...] [COMMAND [COMMAND PARAMETERS...]] If no command is given, it starts the interactive prompt. * Menu: * Command-line Options:: Classic UNIX options. * General Commands:: Main commands.  File: cdcd.info, Node: Command-line Options, Next: General Commands, Up: Invocation Command-line options ==================== Cdcd accepts three options. `-h' `--help' Print a summary of the command-line options and commands to Cdcd and exit. `-v' `--version' Print the version number of Cdcd and exit. `-d DEVICE' `--device=DEVICE' Use DEVICE as the device name. The default is `/dev/cdrom'. *Note The `device' command: Changing CDs, to change the device using a command.  File: cdcd.info, Node: General Commands, Prev: Command-line Options, Up: Invocation General Commands ================ The commands described in this section can be used either from the command-line, like this: cdcd COMMAND [ARGUMENTS...] or from Cdcd's root prompt. *Note The Cdcd Prompt::, for more info. * Menu: * Playing:: Playing. * Moving:: Moving around. * Displaying:: Displaying useful information. * Changing CDs:: Opening and closing the tray; managing multi-CD drives. * Volume Control:: Changing the drive's volume level. * Other Commands:: Miscellaneous commands.  File: cdcd.info, Node: Playing, Next: Moving, Up: General Commands Playing ------- * The `play' command may be used to play a track. play [START-TRACK [START-TIME] [END-TRACK]] A track is either a track number, or a part of a track name (case-insensitive). A time is in the `MM:SS' form, e.g. `3:12', `:24', `1:'. * You can stop the CD drive from playing, with the `stop' command. * The `pause' and `resume' commands can be used to temporarily pause the playing of a CD track, allowing the user to resume the play where it was paused, unlike `stop'. The `toggle' command switches between pausing and playing the current song. * The `rndplay' command plays a random track.  File: cdcd.info, Node: Moving, Next: Displaying, Prev: Playing, Up: General Commands Moving around ------------- * You can start playing the next or previous track with the `next' and `prev' commands. * The `ff' and `rew' commands let you change the playing position within the current track. ff [MM:SS] rew [MM:SS] For example, `ff 3:12' will jump forward by 192 seconds; `rew :12' will jump backward by 12 seconds. The default time to jump is 15 seconds; i.e. `ff' means `ff :15'.  File: cdcd.info, Node: Displaying, Next: Changing CDs, Prev: Moving, Up: General Commands Displaying Useful Information ----------------------------- * The `status' command gives bare-bones information about the status of the CD. For more information, use the `info' command below. * The `info' command displays statistics about the CD, such as the name, artist, track number, time, etc. * Cdcd will display the album, artist, track length and track titles with the `tracks' command. If a track line contains the `>' marker, it means it is the current track. * The `ext' command gives the extended information of the CD or a track. ext ext TRACKNAME ext TRACKNUM ext disc  File: cdcd.info, Node: Changing CDs, Next: Volume Control, Prev: Displaying, Up: General Commands Changing discs -------------- * You can open and close the disc tray with the `open'/`eject' and `close' commands. * The `device' command lets you change the device name that Cdcd controls (default `/dev/cdrom'). *Note The `--device' option: Command-line Options, for information about setting the device with a command-line option. device DEVICE Multi-disc Drives ................. If you own a drive that supports several discs (a cd changer), you can use the following commands to control it. * The `slot' command lets you choose which slot to activate. slot DISC-NUMBER where DISC-NUMBER is the number of the slot you want to activate. * The `list' command will display the entire contents of your changer. _Note_: CD changers are not supported on all platforms.  File: cdcd.info, Node: Volume Control, Next: Other Commands, Prev: Changing CDs, Up: General Commands Controlling the Drive's Volume ------------------------------ * The `setvol' command can set the drive's volume. Drives can have from two to four channels. The four channels are: front left (`fl'), front right(`fr'), back left (`bl') and back right (`br'). Two-channel drives only use the front channels. Each channel volume can be set to a value between 0 and 255 inclusive. setvol [VOLUME] [f=VOLUME] [b=VOLUME] [l=VOLUME] [r=VOLUME] [fl=VOLUME] [fr=VOLUME] [bl=VOLUME] [br=VOLUME] * The `getvol' command displays the volume settings. *Note*: if you listen to your tracks through a mixer-capable device such as a sound card, it is best to leave the drive's volume settings to the default (usually 255), since the drive's mixer is basic and is less easily controlled. The `setvol' and `getvol' commands are provided only for completeness. Use `/dev/mixer' instead.  File: cdcd.info, Node: Other Commands, Prev: Volume Control, Up: General Commands Other Commands -------------- * The `refresh' command looks up for the current CD's information in the cd databases online, and updates it. * You can control Cdcd's verbosity with the `verbose' command. When verbosity is off, Cdcd will display only necessary information. verbose on verbose off  File: cdcd.info, Node: The Cdcd Prompt, Next: Bugs, Prev: Invocation, Up: Top The Cdcd Prompt *************** When you invoke Cdcd with no command on the command-line, for example `cdcd', then you enter the interactive prompt. The output looks like this: cdcd 0.5.6 Copyright (C) 1998, 1999 Tony Arcieri. Copyright (C) 2001 Fabrice Bauzac. cdcd is free software, covered by the GNU General Public Licence, and you are welcome to change it and/or distribute copies of it under certain conditions. There is absolutely no warranty for cdcd. See the file COPYING for details. Using libcdaudio 0.99.5. Enter ? for help. cdcd> The prompt, `cdcd>', tells us that we are in the "root" directory of commands. Here is a table of all the command directories in Cdcd: `(root)' The main directory. You can use all of the basic commands. *Note General Commands::, for information about the basic commands. `sites' From this directory, you can manipulate your list of cd database servers. `edit' This directory is used to modify the contents of the current disc's database entry: artist, album, track names... `access' The access commands are in this directory. They permit you to change the online/offline setting, and the proxy configuration. * Menu: * The Directories System:: How to switch from a directory to another. * Miscellaneous Root Commands:: Useful commands when you are in interactive mode. * The Sites Directory:: Managing servers. * The Edit Directory:: Building a new cd database entry. * The Access Directory:: Access parameters.  File: cdcd.info, Node: The Directories System, Next: Miscellaneous Root Commands, Up: The Cdcd Prompt The Directories System ====================== The commands in Cdcd are organized in groups: general commands, commands related to edition of the CD info, etc. Because these groups are nested, they are called directories. The directories are root, `edit', `access', and `sites'. The prompt tells you in which directory you are. e.g. `cdcd>' means that you are in the root directory, whereas `cdcd/access>' means you are in the `access' directory. You can change the current directory in two ways. * You can go into one subdirectory typing its name. e.g. if you are in the root directory and want to go to the `sites' subdirectory, type `sites'. * You can go back up one directory typing "`..'"; e.g. if you are in the `edit' subdirectory and type "`..'", then you'll be in the root directory. You can use the `help' command to list all of the available commands in the current directory. `?' is an alias for `help'. You can display information about a particular command with the following syntax: help COMMAND Then Cdcd will display the on-line help for the command COMMAND.  File: cdcd.info, Node: Miscellaneous Root Commands, Next: The Sites Directory, Prev: The Directories System, Up: The Cdcd Prompt Miscellaneous Root Commands =========================== Most of the root commands have been already described, in the case of non-interactive use; *Note General Commands::, for more information. Some commands can be used specifically in interactive Cdcd: * `!' is the generic shell call. You can execute a shell from within Cdcd with this command: just type `!'. You can execute any program by typing it and its arguments after the `!'; e.g. `! ls -l ~rms'. * `debug' shows a number of debugging information. * `quit' lets you quit Cdcd. `exit' is an alias. You can type `C-d' (also known as `^D') too.  File: cdcd.info, Node: The Sites Directory, Next: The Edit Directory, Prev: Miscellaneous Root Commands, Up: The Cdcd Prompt The Sites Directory =================== The `sites' directory can be used to customize the list of CD database servers. * ``refresh' [URL]' updates the CDDB server list from the default server or from the specified URL. * `display' shows the current buffer list. * ``add' LOCATION url=URL TYPE' adds url URL with type TYPE (one of `CDDB' or `CDI') at position number LOCATION in the list. * ``del' LOCATION' deletes the entry number LOCATION from the list. * ``move' SOURCE DESTINATION' moves the entry number SOURCE to position number DESTINATION.  File: cdcd.info, Node: The Edit Directory, Next: The Access Directory, Prev: The Sites Directory, Up: The Cdcd Prompt The Edit Directory ================== The `edit' directory is used to edit the information about a CD: the album name, artist, and track names. * ``name' [NAME]' is the command to get (if NAME is not supplied) or set (if it is) the disc name. * ``artist' [ARTIST]' is for the artist for the whole CD. * ``genre' [GENRE]' for the genre. * ``track' TRACKNUM [TITLE]' for the track number TRACKNUM's title. * With the `submit' command, you can submit your modifications to a cd database such as CDDB or CDIndex. submit [EMAIL] You have to specify an e-mail address.  File: cdcd.info, Node: The Access Directory, Prev: The Edit Directory, Up: The Cdcd Prompt The Access Directory ==================== The `access' directory permits the user to configure the access to the internet. * `access' displays the current access method. * `remote' sets the current access method to `remote', i.e. Cdcd will try to connect to remote databases. * `local' sets the current access method to `local', i.e. Cdcd will only access the database locally, and not attempt to reach the outside world. * ``proxy' [URL | off]' sets the current HTTP proxy to URL or turns proxying off. Without argument, it shows the current status.  File: cdcd.info, Node: Bugs, Next: Concept Index, Prev: The Cdcd Prompt, Up: Top Reporting Bugs ************** If you find a bug, please report it to .
