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 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) 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., 59 Temple Place, Suite 330, Boston, MA 02111-1307 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) year 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. , 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. bless-0.6.3/NEWS000066400000000000000000000145731374060072200133420ustar00rootroot00000000000000Bless v0.6.3 20201011 --------------------- * Add plugin to allow copying the current offset to clipboard (gh #15). * Fix display of Courier font glyphs (gh #25). * Use Gtk.Builder for UI loading, drop libglade (gh #2). * Move to the meson build system, drop autotools. * Fix crash when plugins directory path is a file (gh #32). * Add binary+ASCII layout file (gh #23). * Fix issue with statusbar not showing all information (gh #14).

Contents 1. Description 2. Project Web Site and contact info 3. Requirements 4. Installation 5. Running 6. Documentation 7. Known Issues -------------- 1. Description -------------- Bless is a binary (hex) editor, a program that enables you to edit files as a sequence of bytes. It is written in C# and uses the Gtk# bindings for the GTK+ toolkit. Bless is distributed under the terms of the GNU General Public License (GPL-2.0-or-later). See the file COPYING for more information. Main Features ------------- * Efficient editing of large data files. * Raw disk editing. * Multilevel undo - redo operations. * Customizable data views. * Fast data rendering on screen. * Multiple Tabs. * Fast Find and Replace operations. * Conversion Table. * Advanced Copy/Paste capabilities. * Multi-threaded search and save operations. * Export to text and html (others with plugins). * Extensibility with Plugins. Planned Features ---------------- * Scripting language for binary file manipulation. ------------------------------------ 2. Project Web Site and contact info ------------------------------------ More information, bug reports and the latest releases can be found at: https://github.com/afrantzis/bless I can be contacted at: alf82 [at] freemail [dot] gr. --------------- 3. Requirements --------------- The main target platform for bless is GNU/Linux. However, all the libraries it uses are cross-platform, so bless should be able to run without problems on all the major platforms (GNU/Linux, *BSD, Solaris, Win32). To build and run the current version of bless you need: * GTK+ >= 2.8.x (Included in all modern GNU/Linux distributions, http://www.gtk.org) * mono/.NET runtime and C# compiler >= 1.1.14 (http://www.mono-project.com) * Gtk# bindings >= 2.8 for GTK+ (http://gtk-sharp.sourceforge.net) * pkg-config (Included in all modern GNU/Linux distributions) * meson >= 0.46 * nunit and nunit-console, if you want to build and run tests * xsltproc and docbook stylesheet, if you want to produce HTML documentation Development is done using the latest stable versions of the above libraries. Although using an older version may be OK, there is no guarantee that there will not be problems. --------------- 4. Installation --------------- Quick: git clone https://github.com/afrantzis/bless meson setup build (-Dopt=val --buildtype=type ...) ninja -C build (ninja -C build install) Detailed: Step 1: Get the source --------------------------------- To get the latest source: git clone https://github.com/afrantzis/bless For a compressed tarball use: tar -xf bless-a.b.c.tar.gz Step 2: Configure the build ----------------------------- Enter the directory created in the previous step (bless or bless-a.b.c). To configure the build and check that your system has all the required libraries use: $ meson setup build (-Dopt=val --buildtype=type ...) Use the "-Dprefix=PREFIX" option to set the installation directory prefix. By default the prefix is '/usr/local'. You can use the "--buildtype=release" option to build bless in release mode, by default the debug mode is built. Step 3: Build the program ----------------------------- Type 'ninja -C build'. This will create 'bless.exe' and the necessary library files in the build/src directory. You can also type 'ninja -C build test' to run some tests on various bless components. Note that running the tests requires the 'nunit-console' binary. Step 4: Install the program (optional) -------------------------------------- Become root and type 'ninja -C build install'. ---------- 5. Running ---------- If you chose to install the program, just type 'bless'. In any case you can run the program by typing 'mono build/src/bless.exe' from within the top source directory. Enjoy! ---------------- 6. Documentation ---------------- The doc/ directory contains documentation directed both at the user and at the developer who wants to explore Bless. The doc/user/ subdirectory contains information about using bless whereas doc/developer/ contains developer information (bless api etc). Note: The developer documentation is almost non-existent. --------------- 7. Known Issues --------------- * To be able to save a file under the same name (File->Save command) you need to have (temporarily) enough disk space to hold both the original and the new file. This happens because the new file is created in the /tmp directory and then moved to its proper position. For example if you have a 20MB file and edit it so that it becomes 21MB and the new file is supposed to be saved in the same storage device as /tmp, you need to have 20+21=41MB free space in that storage device to be able to save it. After a successful save, the original file is deleted, in this case freeing 20MB. Although this can be a problem (when there is not enough disk space), it can also be seen as a safety measure in case something goes wrong when saving.

See at https://github.com/afrantzis/bless/issues/25 for more information. We ship a TTF version here to ensure we have a nice looking default Courier font even on systems that don't ship one, or on which the Courier font is problematic. The font name of bless-courier.ttf is 'BlessCourier', to allow using the 'Courier' font name for system-wide Courier font if needed. bless-0.6.3/data/bless-16-bytes-per-row.layout000066400000000000000000000016151374060072200210550ustar00rootroot00000000000000 dark red white dark red white dark green white 16 upper dark green white bless-0.6.3/data/bless-48x48.png000066400000000000000000000102601374060072200161540ustar00rootroot00000000000000PNG  IHDR00WbKGD pHYs  tIMEf=IDATxieowmْ d#!

Feedback To report a bug or make a suggestion regarding the &app; application or this manual, please use the Bless bug page. Bless Introduction &app; is a binary (hex) editor, a program that enables you to edit files as sequences of bytes. It is written in C# and uses the Gtk# bindings for the GTK+ toolkit. &app; provides the following features: Efficient editing of large data files. Multilevel undo - redo operations. Customizable data views. Fast data rendering on screen. Multiple tabs. Fast find and replace operations. A data conversion table. Advanced copy/paste capabilities. Highlighting of selection pattern matches in the file. Exporting to text and html. Extensibility with plugins. Building and Installing Bless

&app; &appversion; requirements The main target platform for &app; is GNU/Linux. However, all the libraries it uses are cross-platform, so &app; should be able to run without problems on all the major platforms (GNU/Linux, *BSD, Solaris, Win32). To build and run &app; &appversion; you need: GTK+ >=2.8.x (Included in all modern GNU/Linux distributions, http://www.gtk.org) mono/.NET runtime and C# compiler >= 1.1.14 (http://www.mono-project.com) Gtk# >=2.8 bindings for GTK+ (http://gtk-sharp.sourceforge.net) pkg-config (Included in all modern GNU/Linux distributions) meson >=0.46 nunit and nunit-console, if you want to build and run tests xsltproc and docbook stylesheet, if you want to produce HTML documentation Development is done using the latest stable versions of the above libraries. Although using an older version may be OK, there is no guarantee that there will not be problems.
Installation guide If you downloaded bless as a distribution specific package (eg .rpm, .deb, .tgz) follow your distribution's instructions on how to install packages. If you downloaded Bless from the git repo, or as a source .tar.gz or .tar.bz2 package you will need to build it and install it manually. The building and installation procedure is described below: Overview: git clone https://github.com/afrantzis/bless, meson setup build (-Dopt=val --buildtype=type ...), ninja -C build, (ninja -C build install) Step 1: Get the source To get the latest source: git clone https://github.com/afrantzis/bless For a compressed tarball use: tar -xf bless-a.b.c.tar.gz Step 2: Configure the build Enter the directory created in the previous step (bless or bless-a.b.c). To configure the build and check that your system has all the required libraries use: meson setup build (-Dopt=val --buildtype=type ...) Use the --prefix=PREFIX option to set the installation directory prefix. By default the prefix is '/usr/local'. You can use the --buildtype=release option to build bless in release mode. By default the debug mode is built. Step 3: Build the program Type ninja -C build. This will create bless.exe and the necessary libraries in the build/src directory. You can also use ninja -C build test to run some tests on various bless components. Note that running the tests requires the nunit-console binary. Step 4: Install the program (optional) Become root and type ninja -C build install.
Getting Started
To Start &app; You can start &app; in the following ways: Applications menu Choose Programming/Development Bless Hex Editor . Command line To start &app; from a command line, type the following command, then press Return: bless filenames where filenames are the names of the files you want to open. If you don't specify any files, &app; will try to load the previous session. If that fails &app; will open an empty file for you.
When You Start &app; When you start &app;, the following window is displayed.
&app; Start Up Window Shows &app; main window. Contains titlebar, menubar, toolbar, display area, and scrollbars. Menubar contains File, View, Settings, and Help menus.
The &app; window contains the following elements: Menubar The menus on the menubar contain all of the commands you need to work with files in &app;. Toolbar Provides shortcuts to the commands that are most frequently used when working with files in &app;. Data View The data view contains multiple tabs that display the data of the files you are editing. Conversion Table The conversion table displays the bytes at the current file position converted to various formats. Statusbar The statusbar displays information about current &app; activity and information about the current file.
Using &app;
Working with files &app; supports multiple tabs in the Data View. Each tab contains data that belong to either an existing or a new file. In case the data is related to an existing file, the file's name is displayed on the tab label. Otherwise the tab is marked with a name of the form "Untitled N", where N is a number. When a file has been modified since its last save, an asterisk "*" is displayed next to its name. &app; can currently handle regular files and block device files (eg /dev/hda).
Creating a new file To create a new file for editing use Ctrl N File New . This action creates a new tab with an empty file.
Opening an existing file To open an existing file for editing use Ctrl O File Open . You may also open one or more existing files by dragging and dropping them into the &app; window. This action normally creates a new tab containing the opened file. An exception to this happens when the tab that was active before opening the new file contained an empty file. In that case the old tab is replaced with the new one.
Saving a file To save a file make sure the tab that contains it is active and use Ctrl S File Save . To save a file under a different name or at another location, make sure the tab that contains it is active and use Shift Ctrl S File Save As . If the data in a tab isn't related to an existing file (for example if it is a new file), the Save action actually performs a Save As action.
Closing a file To close a file, make sure the tab that contains it is active and use Ctrl W File Close . You can also close a file by clicking on the close icon on its tab label:
Closing a tab Shows how to close a tab using the close icon on its tab label
If the file has changed since the previous save you will be prompted to save it.
Changing the active file You can switch between tabs, therefore making the file the tab contains the active one, using a number of ways: By clicking on the tab label of the tab you want to switch to. By pressing AltN, where N is the number of the tab you want to switch to. This method works for the first nine tabs. For example to switch to the second tab you should press Alt+2. By pressing AltLeft arrow or AltRight arrow, you can switch to the tab immediately to the left or right of the currently active tab.
Data View basics The Data View is the part of &app; that displays the data of the files you are editing and enables you to manipulate them. It consists of (possibly) many tabs, each corresponding to a file you are editing. Each tab contains areas that display the file's data in various formats. An area can be one of the following types: Offset Area: Displays the offset of the first byte at the specified row. Separator Area: Displays a vertical separator line. Hexadecimal Area: Displays the data in hexadecimal number base. Decimal Area: Displays the data in decimal number base. Octal Area: Displays the data in octal number base. Binary Area: Displays the data in binary number base. Ascii Area: Displays the data as Ascii text. The types and placement of the areas that each tab contains can be customized with layout files. See for more information on how to write and use layout files.
Selecting the active area At any time only one of the areas accepts and handles editing events. This area is said to have the focus. All areas except Offset and Separator may have the focus.
Cursor in focused and not focused areas Shows the difference in the cursor when an areas has the focus or not.
The cursor in the focused area consists of a horizontal line under the current byte and a vertical line just before the active digit of the current byte. In contrast, the cursor in a non-focused area consists of only the horizontal line beneath the current byte. Changing the area that has the focus can be done in two ways: Using the TAB key cycles the focus among the available areas. Pressing or releasing the left mouse button in an area, or moving with the left mouse button pressed into an area, gives the focus to that area. If the area can't accept the focus (eg it is a Separator area), the focus remains unchanged.
Scrolling If the file you are editing is big enough, only a small range of its data will be visible in the Data View. The size of the visible data is called a page and changes as the &app; window is resized. To change the visible range of a file's data you should scroll the Data View. You can scroll the Data View in two ways: Using the scrollbar that is located at the right side of the Data View. The scrollbar is visible only if the file is too large to fit in one page. Using the wheel on your mouse, if it has one. Scrolling the Data View does not change the cursor position.
Editing a file
Basic editing operations
Changing the current cursor position You can move the cursor in two ways: Using the keyboard Pressing the Up Arrow key moves the cursor to the byte just above the current one. Pressing the Down Arrow key moves the cursor to the byte just below the current one. Pressing the Left Arrow key moves the cursor to the previous digit of the current byte. If the cursor was at the first digit of a byte, it is moved to the last digit of the previous byte. Pressing the Right Arrow key moves the cursor to the next digit of the current byte. If the cursor was at the last digit of a byte, it is moved to the first digit of next byte. Pressing the Page Up key moves the cursor to the byte which is one page before the current position. Pressing the Page Down key moves the cursor to the byte which is one page after the current position. Pressing the Home key moves the cursor to the first byte in the file. Pressing the End key moves the cursor one byte after the last byte in the file. Using the mouse Clicking on a digit of a byte moves the cursor to that byte and digit. If the new cursor position is outside the currently visible page of data, the view scrolls automatically so that the new cursor position is made visible.
Moving the cursor to a specific position To access the Go to Offset Bar use: Ctrl G Search Go to Offset .
Go to Offset Bar Go to Offset Bar
To move the cursor to a specific position in the file: Type the offset in the Offset text entry (in the desired number format). if the typed offset starts with '0x' it is considered hexadecimal, if it starts with '0' it is considered octal, otherwise it is considered decimal. Press the Go to Offset button
Selecting a range of data There are three ways to select a range of data from the file you are editing: Using the keyboard Position the cursor at one end of the range you want to select. Hold down the Shift key and move the cursor to the other end of the range using the keyboard. As you move the cursor, the currently selected data range will be highlighted. Release the Shift key. Using the mouse Position the cursor at one end of the range you want to select. Hold down the Left mouse button and move the cursor to the other end of the range using the mouse. As you move the cursor, the currently selected data range will be highlighted. Release the Left mouse button. ...alternatively, while pressing the Shift key, position the mouse pointer over the other end of the selection and click using the Left mouse button. Using the Select Range Bar To access the Select Range Bar use: Ctrl Shift R Edit Select Range .
Select Range Bar Select Range Bar
To select a range: Type the starting offset in the from text entry (in the desired number format). if the typed offset starts with '0x' it is considered hexadecimal, if it starts with '0' it is considered octal, otherwise it is considered decimal. Type the ending offset in the to text entry (in the desired number format). if the typed offset starts with '0x' it is considered hexadecimal, if it starts with '0' it is considered octal, otherwise it is considered decimal. Instead of specifying an absolute ending offset you can specify the length of the selection. To do this type the length in the to text entry, prepending it with either '+' or '-'. The '+' or '-' specify the direction of the selection: '+' means select towards the end of the file and '-' means select towards the beginning. The selected range always contains the starting offset. Selecting a range of data has another useful effect: all the patterns matching the selected data in the file are highlighted, thus providing a quick way to find or emphasize patterns. The color of the highlighting can be changed using Layout files (see ). This feature can be turned off in the Preferences Dialog (see ). The patterns matching the selected data are highlighted only if the selected data size is at most 1024 bytes.
Toggling Overwrite/Insert edit mode By pressing the Insert key on the keyboard or by clicking on the edit mode statusbar, you can change the edit mode &app; is currently in. The edit mode determines what happens when you add new data to the file. There are two available modes: Insert Mode The new data is inserted at the current cursor position. &app; automatically makes space for the new data. Overwrite Mode The new data overwrites the old data, starting from the current cursor position.
Edit mode statusbar display Shows the edit mode display in the statusbar
The current edit mode is displayed at the far right in the statusbar.
Changing the statusbar number base You can change the number base of the information displayed in the statusbar (current offset, current selection). Clicking on the Offset or Selection information in the statusbar cycles among Hexadecimal, Decimal and Octal number bases. You can distinguish the current number base by checking the prefix of displayed numbers. A "0x" prefix denotes Hexadecimal, a "0" prefix denotes Octal and no prefix denotes Decimal.
Statusbar number base Shows statusbar information in several number bases
Modifying the data You can directly modify the data in a file by using the keyboard: Inserting a new byte at a specific position Make sure you are in Insert Mode. Move the cursor to the first digit of desired position. Press the keys which correspond to the digits of the desired byte. Each keypress automatically moves the cursor one position to the right. Modifying an existing byte Make sure you are in Overwrite Mode (only required if you want to modify the first digit of a byte). Move the cursor to desired byte/digit position. Press the keys which correspond to the digits of the desired byte. Each keypress automatically moves the cursor one position to the right. Appending data to the end of the file Move the cursor to the position just after the last byte in the file. Press the keys which correspond to the digits of the desired byte. Each keypress automatically moves the cursor one position to the right. Each area accepts only certain digits (eg the hexadecimal area accepts only 0-9 and A-F). If a key (representing a digit) is pressed in an area that doesn't accept it, the keypress is ignored.
Clipboard operations Bless features an advanced system to handle clipboard operations.
Copy and Cut operations To copy the selected data to the clipboard use: Ctrl C Edit Copy . To cut the selected data from the file and copy it to the clipboard use: Ctrl X Edit Cut . When copying or cutting data, that data becomes available to &app; and other applications as well. &app; can offer its data to other applications in two main formats: Raw bytes &app; can offer the selected data as raw bytes to applications that can handle it, for example other hex editors. This is the format &app; uses when interacting with itself (for example when you copy from a tab and paste into another). UTF-8 string &app; can offer a string representation of the selected data in various number bases or UTF-8 text. The number base is determined by the type of the area that has the focus at the end of the selection action for the cut/copied data. For example if that area is hexadecimal, the offered string will contain the hexadecimal string representation of the selected data. If the ending area is the text area, the offered string will contain the UTF-8 text represented by the selected data (if possible).
Paste operation To paste data from the clipboard to the current cursor position use: Ctrl V Edit Paste . The value of the Overwrite/Insert mode, affects the way paste operations function. If the mode is Insert, the pasted data is inserted at the current cursor position. If the mode is Overwrite, the pasted data overwrites the data from the cursor position and on, as needed. Pasted data can originate from &app; itself or some other application. &app; can accept data in two formats: Raw bytes This is the format &app; uses when interacting with itself (for example when you copy from a tab and paste into another). External applications that offer raw bytes are usually other hex editors. UTF-8 string &app; can accept data as a UTF-8 string (for example, from a text editor). It tries to parse the data and convert it to raw bytes according to the type of the area that currently has the focus. For example if the focus is in an octal area, &app; will try to parse the string as a sequence of bytes represented in octal format. If the parse fails, the data will be inserted as UTF-8 text (as if they had been pasted into a text area).
Copy offset(s) operations To copy the offset(s) of the current cursor position or the currently selected range use: Ctrl Shift C Edit Copy Offset(s) . This operation is also available in the pop-menu when right-clicking in the Data View. If there is an active selection this operation copies the start and end offsets of the selection to the clipboard, separated by a comma. Otherwise, just the offset of the cursor position is copied to the clipboard. The number base used for the offsets is determined by a plugin preference which can be set through the preferences dialog. See .
Undo/Redo operations To undo previous actions use: Ctrl Z Edit Undo . To redo previously undone actions use: Shift Ctrl Z Edit Redo .
Exporting Data &app; features an advanced and customizable export system. It can currently export data to text or html files.
Export Patterns The exporting is based on an export pattern. The pattern consists of string literals and special command strings. The literals are printed in the output file as they are whereas the command strings tell the exporter to do something. Commands strings are enclosed in '%'s and specify the command and its parameters. The command is specified by an uppercase letter and the parameters by lowercase letters. Each letter (whether it corresponds to a command or a parameter) may be followed by an argument enclosed in double quotes '"'. Command Description Parameters [default] Export (E) Writes actual data. E: the number of bytes to export ["1"] p: the prefix to write before each byte [""] s: the suffix to write after each byte [""] x: the separator to use between bytes [""] e: the string to use for not printed bytes (due to alignment) [" "] t: the type to export the byte(s) to (see below) ["H"] Ignore (I) Ignores data. I: the number of bytes to ignore ["1"] Offset (O) Writes the current offset. O: the number of digits to use for writing the offset ["8"] t: the type to write the offset in (see below) ["H"] Export Type Description H Hexadecimal with uppercase characters h Hexadecimal with lowercase characters D Decimal O Octal B Binary A Ascii Command strings can be grouped together with square brackets '[',']'. After such a group of commands is executed the pointer which keeps track of the next byte to export is reset to the position it had just before the group was executed. Some sample patterns and their output will make things much clearer: %O"4"%: %E"4"p"0x"x" "% - %E"4"p"0x"x" "%\n 0000: 0x00 0x01 0x02 0x03 - 0x04 0x05 0x06 0x07 0008: 0x08 0x09 0x0a 0x0b - 0x0c 0x0d 0x0e 0x0f 0010: 0x10 0x11 0x12 0x13 - 0x14 0x15 0x16 0x17 0018: 0x18 0x19 0x10 0x1a - 0x1b 0x1c 0x1d 0x1e 0020: 0x1f - [%E"2"% %I"2"% %E"2"% %I"2"%] %I"2"% %E"2"% %I"2"% %E"2"%\n 0001 0405 0203 0607 0809 0c0d 0a0b 0e0f 1011 1415 1213 1617 1819 1b1c 101a 1d1e 1f

To apply a bitwise operation on a range of data: Select the range to apply the operation on (see ). If no range is selected the operation will be performed on the current offset. The selected range is displayed at the far left of the bar. Clicking on the displayed range cycles the number base used to display it (Hexadecimal, Octal, Decimal). Select the desired operation from the operations list. Available operations are AND, OR, XOR and NOT. Type the data to use for the operation in the data text entry (if applicable). Select the type of the data from the data type list. Press the Execute button to perform the operation.
Customizing &app;
Configuration Files &app; keeps its configuration files under $XDG_CONFIG_HOME/bless (usually $HOME/.config/bless on UNIX based systems and C:\Documents and Settings\User Name\Application Data\bless on MS Windows systems) in accordance to the XDG specification. This directory contains the following files and directories export_patterns Keeps the list of saved export patterns. history.xml Keeps the list of recently opened files. last.session Keeps the state of &app; the last time it was closed. This includes the open files, the file offset and cursor offset in each file, the active file, the window dimensions etc. preferences.xml Keeps the user preferences. layouts/ This directory holds the layout description files for each user. See .
Preferences You can edit the user preferences in the Preferences dialog. It can be accessed by using Edit Preferences... .
General Preferences

Default Layout Layout File The layout file to use when opening a new tab. If it is left empty a default will be used. Use layout of currently active tab if any If it is checked, &app; will try to use the layout of the currently active tab for new tabs. If there are no open tabs, &app; will use the file from the "Layout File" preference. Misc Default edit mode The edit mode new tabs will be placed in (Insert or Overwrite). Temporary Directory The directory to save temporary files into (leave blank for default eg /tmp). When a file is saved, it is saved into this directory and then moved to its final position.

Undo Limit Limit to X actions Limit the number of actions that can be undone to X actions. Unlimited Undo Don't limit the number of actions that can be undone. Keep Undo History After Save Always Always keep undo history after a file is saved. When dealing with large amounts of undo data this option may fill up all memory and cause a severe degradation of system performance. What fits in main memory Only keep the part of the history that fits in main memory (RAM). Never Never keep undo history after a file is saved.
Session Preferences
Session Preferences Session Preferences
Load previous session on startup Whether the previous session (the state of Bless at the time of the last quit) should be loaded on startup. The state includes all open files, the focused tab, the focused area in each file, the cursor position in each file and the window geometry. Ask before loading session Ask before loading session on startup. Remember cursor position Whether &app; should remember and restore the position of the cursor in each of the loaded files when loading the previous session. Remember window geometry Whether &app; should remember and restore the window size when loading the previous session.
Layout Files The way &app; presents the data is highly customizable. The configuration is done through layout description files. Currently there is no way to graphically edit the layouts but one is planned for a later version.
Selecting a layout &app; searches for layout description files in the $XDG_CONFIG_HOME/bless/layouts directory (usually $HOME/.config/bless/layouts). You can preview and select the available layouts with the layout selection dialog, which can be accessed by using View Layouts .
Creating Layout Files Layout description files are XML files ending with the .layout suffix. They consist of the <layout> tag which contains a series of <area> tags that describe each area in the layout. The <area> tag takes one attribute, type, which defines the type of the area. The valid values for type are: Type Description hexadecimal Displays the data in hexadecimal format. decimal Displays the data in decimal format. octal Displays the data in octal format. binary Displays the data in binary format. ascii Displays the data in ascii format. offset Displays the data offset. separator A vertical line that visually separates areas. For example, the following simple layout file: <layout> <area type="offset"></area> <area type="hexadecimal"></area> <area type="offset"></area> <area type="separator"></area> <area type="ascii"></area> </layout> produces the standard offset-hex-ascii view with default colors:
Standard offset-hex-ascii view Standard offset-hex-ascii view
Each area may include additional options about how to display the data. Some options are available to all areas whereas others are area-specific. The options that aren't explicitly defined assume their default values. Also if an option is specified for an area that doesn't support it, the option is just ignored. Option Values Description Areas display see below The fonts and colors that should be used for the display. all case upper|lower Whether to display hexadecimal values using lowercase or uppercase. offset, hexadecimal grouping #int The number of bytes that should be grouped together in each column. hexadecimal, decimal, octal, binary bpr #int The number of bytes on each row in the area (see below for more information) hexadecimal, decimal, octal, binary, ascii bytes #int The number of bytes which will be used to display offsets (default 4) offset
The bpr option The <bpr> (bytes per row) option sets the (maximum) number of bytes that each row in an area can have. If it is not specified, the number of bytes on each row changes dynamically in order to fill the whole available width. If it is specified in at least one area in the layout all the areas in the layout conform to the specified restriction. In case of a conflict, for example when two areas specify different bprs, the smallest value is used. Finally, if there is a conflict between bpr and grouping values, the highest value that conforms to the grouping and is below the bpr is used (eg if bpr=5 and grouping=2 the bytes per row will be 4).
The display option The <display> option is the most complicated of the lot and deserves additional explanation. Bless distinguishes between even and odd rows, and even and odd columns. You can choose how to color each of the above items thus creating a visual result tailored to your needs. This is achieved by using the <display> tag. Note that the first row and column are numbered as 0 and are therefore considered even. A <display> tag may contain a <font> tag which sets the font family and size to use for displaying data in the area (eg "Courier 10"). The font should be a monospaced font, otherwise the data in the area won't be displayed correctly. It is also advised to use same sized fonts in all the areas so that the data is correctly aligned. A <display> tag may also contain a <evenrow> and a <oddrow> tag which describe how the even and odd rows will look like. Each of the <evenrow> and <oddrow> tags may contain a <evencolumn>, an <oddcolumn>, a <selectedcolumn> and a <patternmatchcolumn> tag. The first two describe the appearance of the respective columns under normal conditions (no highlighting). The <selectedcolumn> tag describes the appearance of selected bytes and the <patternmatchcolumn> tag the appearance of the highlighted bytes that match the selected bytes (see ). The description for all the above is accomplished by using the <foreground> and <background> tags which specify the foreground and background colors to use. The colors can be specified either by name (eg dark blue) or by an RGB triad (eg #ff004e).

An example: <layout> <area type="offset"> <display> <evenrow> <evencolumn> <foreground>dark red</foreground> </evencolumn> </evenrow> <oddrow> <evencolumn> <foreground>dark red</foreground> </evencolumn> </oddrow> </display> </area> <area type="separator"> <display> <evenrow> <evencolumn> <foreground>dark green</foreground> <background>white</background> </evencolumn> </evenrow> </display> </area> <area type="hexadecimal"> <grouping>2</grouping> <case>upper</case> <display> <evenrow> <selectedcolumn> <foreground>white</foreground> <background>#8faec8</background> </selectedcolumn> </evenrow> <oddrow> <evencolumn> <background>#eeeeee</background> </evencolumn> <oddcolumn> <background>#eeeeee</background> </oddcolumn> <selectedcolumn> <foreground>white</foreground> <background>#7b96ac</background> </selectedcolumn> </oddrow> </display> </area> <area type="separator"> <display> <evenrow> <evencolumn> <foreground>dark green</foreground> <background>white</background> </evencolumn> </evenrow> </display> </area> <area type="decimal"> </area> <area type="separator"> <display> <evenrow> <evencolumn> <foreground>dark green</foreground> <background>white</background> </evencolumn> </evenrow> </display> </area> <area type="binary"> </area> </layout> The result is:
Example layout Example layout screenshot
Not all font options are used in all areas. The hexadecimal, decimal, octal and binary areas use all options. The ascii, offset and separator areas do not use the <oddcolumn> tag. The */evencolumn/background colors are considered the primary background colors for their respective row. They are used to paint all parts of the row that are not otherwise painted (eg space between columns). The evenrow/evencolumn/background color is also considered the main background color of the area and is used to paint the unused parts of the area.
Extending with plugins As of version 0.5.0 &app; can be extended by using plugins. Internally &app; uses plugins for almost all of its GUI. Currently the parts that can be extended by plugins are: The GUI The areas displayed inside the Data Views Export builders See the developer documentation for more information on how to write plugins (TODO).
Frequently Asked Questions Philosophical Questions Why did you start Bless? Aren't there enough hex editors? There aren't enough free (as in speech) graphical hex editors. The two main ones are khexedit and ghex. Khexedit hasn't been updated in years and ghex is moving very slowly. So, why didn't you contribute to one of the existing projects? I wanted to try out the mono/Gtk# combination for graphical applications and none such project existed. What kind of name is Bless? It is a wordplay on the word hex. Hex also means curse and a bless(ing) is the opposite of a curse. Technical Questions How can I get the latest source of Bless? Bless now uses Git as its version control system. After you install Git on your system use the following command to get the latest version of Bless into the bless directory (this might take some time): git clone https://github.com/afrantzis/bless If you already downloaded a previous version (using the above command, not source tarballs) and want to update to the latest version use: git pull from within the directory that contains the previous version. I don't like the way Bless displays data. Can I change it? Yes! Bless is highly customizable. See I am trying to save a large file (under the same name) but while saving Bless complains that there is no space left! I was sure I had enough space! What's going on? To be able to save a file under the same name (File->Save command) you need to have (temporarily) enough disk space to hold both the original and the new file. This happens because the new file is created in a temporary file directory (eg /tmp see ) and then moved to its proper position. For example if you have a 20MB file and edit it so that it becomes 21MB and the new file is supposed to be saved in the same storage device as /tmp, you need to have 20+21=41MB free space in that storage device to be able to save it. After a successful save, the original file is deleted, in this case freeing 20MB.Although this can be a problem (when there is not enough disk space), it can also be seen as a safety measure in case something goes wrong when saving. A notable exception to the above is when the size of the file to be saved has not been changed. In that case the file is saved in-place. The data in the data areas isn't displayed correctly! What is wrong? On some systems the data in the data areas are garbled. This is an issue with the font subsystem. What happens is that the font subsystem reports to Bless a different font width than the one that is actually used on screen. This bug should be fixed in current versions of Pango. Anyway, the bug is now irrevelevant: since version 0.5.0 &app; uses a different way to measure the font width. Also, the temporary workaround with the FontWidthFix preference introduced in 0.4.1 is now disabled. If you are still experiencing such problems with versions >= 0.5.0 please file a bug report.
