Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. 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 them 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 prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. 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. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey 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; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If 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 convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU 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 that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. 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. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 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. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. 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 state 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 3 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, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program 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, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU 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 Lesser General Public License instead of this License.

The new variable let's the user choose default properties, e.g. a color, for all supported annotations separately. ** Provide a faster "boot-loader" The autoloaded function pdf-loader-install acts as a replacement for pdf-tools-install and makes Emacs load and use PDF Tools as soon as a PDF file is opened, but not sooner. ** Improved the process of (re)compiling the server This obsoletes the variable pdf-tools-handle-upgrades, which does nothing anymore. * Version 0.80 ** Tablist package The files tablist.el and tablist-filter.el are no longer part of pdf-tools, but continue to live on in the tablist package, on which pdf-tools now depends on. ** View *** Encrypted files When encountering an encrypted file, query for a password and attempt to decrypt it. *** Backward sync from isearch In isearch, press M-s s to visit the source of the current match. *** Disable unicode in mode-line New variable pdf-view-use-unicode-lighter which allows for disabling the use of unicode in the mode-line. * Version 0.70 ** View *** Register integration The keys m and ' now set resp. jump to a register corresponding to a position in the PDF. Also '' is handled special: It jumps to the position before the last register-jump. *** Export parts of a page as an image ** Info *** Interface changes The return value of many pdf-info-* functions was changed in order to prefer alists over other data-structures (indexed lists, trees). ** Virtual PDF A virtual PDF is a collection of pages (or parts thereof) of arbitrary documents, which appear to the rest of pdf-tools as one big PDF, though they are always read-only. * Version 0.60 ** Regexp support You may now search for perl-compatible regular expressions (PCRE) in PDF documents, both via Isearch and Occur. If that scares you, customize the variable pdf-occur-prefer-string-search. ** Occur *** Asynchronous search Searching is performed asynchronously in a private server instance, i.e. it doesn't block neither ordinary editing nor pdf-view-mode. *** Moccur Added the ability to search multiple documents in one occur buffer. ** Isearch *** Occur Integration M-s o now starts occur, while keeping the isearch session, like it is in text-buffers. *** Word search M-s w now does a word search, which will also find hyphenated words (as determined by pdf-isearch-hyphenation-character), though not at page boundaries. ** View *** Navigate by pagelabels M-g l may be used to jump to a page by label, i.e. it's displayed number. *** Rendering Added the ability to display the page as it would be printed (e.g. w/o annotations) and to apply a color filter (pdf-view-printer-minor-mode resp. pdf-view-midnight-minor-mode). ** Outline New option `pdf-outline-display-labels', determining whether to display labels instead of plain page-numbers. * Version 0.50 ** PDF Tools is now available on MELPA. ** SyncTeX *** File name handling SyncTeX is pretty picky about source filenames. So instead of trying various filenames and hoping for best, we find it by directly inspecting the database. *** Heuristic backward search Backward searching now tries to find the exact position in the LaTeX buffer. This may be disabled by setting pdf-sync-backward-use-heuristic to nil. *** Renamed most variables/functions/commands. The old ones are still there but declared obsolete. ** Compatible with Emacs 24.3 ** Integrate with bookmark.el ** Compiling on OSX PDF Tools should now compile on OSX, though it is unsupported. ** MELPA Try to handle an update via MELPA by package.el by shutting down the server, recompiling and restarting it. This may be deactivated by setting pdf-tools-handle-upgrades to nil. ** Auto slicing A new minor mode which will automatically slice the page according to it's bounding box. * Version 0.40 I basically reimplemented the whole thing. (Not really, but a lot has changed.) ** Displaying PDF Files. Rendering is now done almost completely in libpoppler (no convert anymore), while PNG images are kept in memory and files are solely used as a means of exchange between Emacs and epdfinfo. In essence, display should be much faster. *** New Major Mode pdf-view Hacking up doc-view.el to support a server-based ,,rendering engine'' would have been to awkward. So a new major-mode was needed : pdf-view-mode . Both are very similar regarding user-interface. Some differences are: + Setting the width to `fit-width', `fit-height' or `fit-page' keeps up with window-size changes. + The values of the slice are relative, i.e. independent of the image-size. *** PNG Image Cache Image data is cached, in order to keep the time it needs to display a page low. Some pages are pre-loaded for the same reason, while idling. The number of cached images per buffer may be customized using `pdf-cache-image-limit'. ** Annotations *** New supported types Provided epdfinfo was build with a recent version of libpoppler, you may now create and modify the following markup annotation types: highlight, squiggly, underline and strike-out. ** Various *** You may now select extended regions with C-mouse-1. *** Numerous other changes pdf-tools-0.90/README000077700000000000000000000000001340723424600156772README.orgustar00rootroot00000000000000pdf-tools-0.90/README.org000066400000000000000000000404411340723424600150270ustar00rootroot00000000000000#+TITLE: PDF Tools README #+AUTHOR: Andreas Politz #+EMAIL: politza@fh-trier.de [[https://travis-ci.org/politza/pdf-tools.svg?branch%3Dmaster][https://travis-ci.org/politza/pdf-tools.svg?branch=master]] [[http://stable.melpa.org/#/pdf-tools][http://stable.melpa.org/packages/pdf-tools-badge.svg]] [[http://melpa.org/#/pdf-tools][http://melpa.org/packages/pdf-tools-badge.svg]] ** About this package PDF Tools is, among other things, a replacement of DocView for PDF files. The key difference is that pages are not pre-rendered by e.g. ghostscript and stored in the file-system, but rather created on-demand and stored in memory. This rendering is performed by a special library named, for whatever reason, poppler, running inside a server program. This program is called ~epdfinfo~ and its job is to successively read requests from Emacs and produce the proper results, i.e. the PNG image of a PDF page. Actually, displaying PDF files is just one part of PDF Tools. Since poppler can provide us with all kinds of information about a document and is also able to modify it, there is a lot more we can do with it. [[http://www.dailymotion.com/video/x2bc1is_pdf-tools-tourdeforce_tech?forcedQuality%3Dhd720][Watch]] Please read also about [[#known-problems][known problems.]] ** Features + View :: View PDF documents in a buffer with DocView-like bindings. + Isearch :: Interactively search PDF documents like any other buffer, either for a string or a PCRE. + Occur :: List lines matching a string or regexp in one or more PDF documents. + Follow :: Click on highlighted links, moving to some part of a different page, some external file, a website or any other URI. Links may also be followed by keyboard commands. + Annotations :: Display and list text and markup annotations (like underline), edit their contents and attributes (e.g. color), move them around, delete them or create new ones and then save the modifications back to the PDF file. + Attachments :: Save files attached to the PDF-file or list them in a dired buffer. + Outline :: Use imenu or a special buffer to examine and navigate the PDF's outline. + SyncTeX :: Jump from a position on a page directly to the TeX source and vice versa. + Virtual :: Use a collection of documents as if it were one, big single PDF. + Misc :: - Display PDF's metadata. - Mark a region and kill the text from the PDF. - Keep track of visited pages via a history. - Apply a color filter for reading in low light conditions. ** Installation The package may be installed via melpa and it will try to build the server part when it is activated the first time. Though the next section regarding build-prerequisites is still relevant, the rest of the installation instructions assume a build from within a git repository. (The melpa package has a different directory structure.) *** Server Prerequisites You'll need GNU Emacs \ge 24.3 and some form of a GNU/Linux OS. Other operating systems are currently not supported (patches welcome). The following instructions assume a Debian-based system. (The prerequisites may be installed automatically on this kind of systems, see [[#compilation][Compilation]] .) First make sure a suitable build-system is installed. We need at least a C/C++ compiler (both ~gcc~ and ~g++~), ~make~, ~automake~ and ~autoconf~. Next we need to install a few libraries PDF Tools depends on, some of which are probably already on your system. #+begin_src sh $ sudo aptitude install libpng-dev zlib1g-dev $ sudo aptitude install libpoppler-glib-dev $ sudo aptitude install libpoppler-private-dev #+end_src On some older Ubuntu systems, the final command will possibly give an error. This should be no problem, since in some versions this package was contained in the main package ~libpoppler-dev~. Also note, that ~zlib1g-dev~ was for a long time called ~libz-dev~, which it still may be on your system. Debian wheezy comes with libpoppler version 0.18, which is pretty old. The minimally required version is 0.16, but some features of PDF Tools depend on a more recent version of this library. See the following table for what they are and what version they require. | You want to ... | Required version | |-------------------------------------------+------------------| | ... create and modify text annotations. | \ge 0.19.4 | | ... search case-sensitive. | \ge 0.22 | | ... create and modify markup annotations. | \ge 0.26 | |-------------------------------------------+------------------| In case you decide to install libpoppler from source, make sure to run its configure script with the ~--enable-xpdf-headers~ option. Finally there is one feature (following links of a PDF document by plain keystrokes) which requires imagemagick's convert utility. This requirement is optional and you may install it like so: #+begin_src sh $ sudo aptitude install imagemagick #+end_src **** Compiling on OS X Although OS X is not officially supported, it has been reported to have been successfully compiled. You will need to install poppler which you can get with homebrew via #+BEGIN_SRC sh $ brew install poppler automake #+END_SRC You will also have to help ~pkg-config~ find some libraries by setting ~PKG_CONFIG_PATH~, e.g. #+BEGIN_SRC sh $ export PKG_CONFIG_PATH=/usr/local/Cellar/zlib/1.2.8/lib/pkgconfig:/usr/local/lib/pkgconfig:/opt/X11/lib/pkgconfig #+END_SRC or likewise within Emacs using `setenv`. After that, compilation should proceed as normal. **** FreeBSD Although not officially supported, it has been reported that pdf-tools work well on FreeBSD. Instead of building pdf-tools, you can install one of the OS packages with, e.g. #+BEGIN_SRC sh $ pkg install pdf-tools-emacs25 #+END_SRC To see the current list of pdf-tools packages for FreeBSD visit [[https://repology.org/metapackages/?search=pdf-tools&inrepo=freebsd][the Repology list]]. To build pdf-tools from either melpa or directly from the source repository, install the dependencies with #+BEGIN_SRC sh $ pkg install autotools gmake poppler-glib #+END_SRC If you choose not to install from melpa, you must substitute ~gmake~ for ~make~ in the instructions below. **** Compiling on Centos It is possible to compile pdf-tools on Centos. Install poppler the dependencies with: #+BEGIN_SRC sh $ yum install poppler-devel poppler-glib-devel #+END_SRC **** Compiling on Fedora #+BEGIN_SRC sh $ sudo dnf install make automake autoconf gcc gcc-c++ ImageMagick libpng-devel zlib-devel poppler-glib-devel #+END_SRC **** Compiling on Alpine Linux #+BEGIN_SRC sh $ apk add build-base g++ gcc automake autoconf libpng-dev glib-dev poppler-dev #+END_SRC **** Compiling on Windows PDF Tools can be built and used on Windows using the MSYS2 compiler. This will work with native (not cygwin) Windows builds of emacs. This includes the standard binaries provided by the GNU project, those available as MSYS2 packages and numerous third-party binaries. It has been tested with emacs 25.1. Instructions are provided under [[#compilation-and-installation-on-windows][Compilation and installation on Windows]], below. PDF Tools will successfully compile using Cygwin, but it will not be able to open PDFs properly due to the way binaries compiled with Cygwin handle file paths. *** Compilation :PROPERTIES: :CUSTOM_ID: compilation :END: Now it's time to compile the source. #+begin_src sh $ cd /path/to/pdf-tools $ make install-server-deps # optional $ make -s #+end_src The ~make install-server-deps~ command will try to install all necessary programs and libraries to build the package, though it'll only work, if ~sudo~ and ~apt-get~ are available. This should compile the source code and create a Emacs Lisp Package in the root directory of the project. The configure script also tells you at the very end, which features, depending on the libpoppler version, will be available. These commands should give no error, otherwise you are in trouble. **** Compilation and installation on Windows If using the GNU binaries for Windows, support for PNG and zlib must first be installed by copying the appropriate dlls into emacs' ~bin/~ directory. Most third-party binaries come with this already done. First, install [[http://www.msys2.org/][install MSYS2]] and update the package database and core packages using the instructions provided. Then, to compile PDF tools itself: 1. Open msys2 shell 2. Update and install dependencies, skipping any you already have #+BEGIN_SRC sh $ pacman -Syu $ pacman -S base-devel $ pacman -S mingw-w64-x86_64-toolchain $ pacman -S mingw-w64-x86_64-zlib $ pacman -S mingw-w64-x86_64-libpng $ pacman -S mingw-w64-x86_64-poppler $ pacman -S mingw-w64-x86_64-imagemagick #+END_SRC 3. Install PDF tools in Emacs, but do not try to compile the server. Instead, get a separate copy of the source somewhere else. #+BEGIN_SRC sh $ git clone https://github.com/politza/pdf-tools #+END_SRC 4. Open mingw64 shell (*Note:* You must use mingw64.exe and not msys2.exe) 5. Compile pdf-tools #+BEGIN_SRC sh $ cd /path/to/pdf-tools $ make -s #+END_SRC 6. This should produce a file ~server/epdfinfo.exe~. Copy this file into the ~pdf-tools/~ installation directory in your Emacs. 7. Start Emacs and activate the package. #+BEGIN_SRC M-x pdf-tools-install RET #+END_SRC 8. Test. #+BEGIN_SRC M-x pdf-info-check-epdfinfo RET #+END_SRC If this is successful, ~(pdf-tools-install)~ can be added to Emacs' config. Note that libraries from other GNU utilities, such as Git for Windows, may interfere with those needed by PDF Tools. ~pdf-info-check-epdinfo~ will succeed, but errors occur when trying to view a PDF file. This can be fixed by ensuring that the MSYS libraries are always preferred in emacs: #+BEGIN_SRC emacs-lisp (setenv "PATH" (concat "C:\\msys64\\mingw64\\bin;" (getenv "PATH"))) #+END_SRC *** ELisp Prerequisites This package depends on the following Elisp packages, which should be installed before installing the Pdf Tools package. | Package | Required version | |-----------+----------------------------------| | [[https://elpa.gnu.org/packages/let-alist.html][let-alist]] | >= 1.0.4 (comes with Emacs 25.2) | | [[http://melpa.org/#/tablist][tablist]] | >= 0.70 | |-----------+----------------------------------| *** Installing If ~make~ produced the ELP file ~pdf-tools-${VERSION}.tar~ you are fine. This package contains all the necessary files for Emacs and may be installed by either using #+begin_src sh $ make install-package #+end_src or executing the Emacs command #+begin_src elisp M-x package-install-file RET pdf-tools-${VERSION}.tar RET #+end_src To complete the installation process, you need to activate the package by putting #+begin_src elisp (pdf-tools-install) #+end_src somewhere in your ~.emacs~. Alternatively, and if you care about start-up time, you may want to use #+begin_src elisp (pdf-loader-install) #+end_src instead. Next you probably want to take a look at the various features of what you've just installed. The following two commands might be of help for doing so. #+begin_src elisp M-x pdf-tools-help RET M-x pdf-tools-customize RET #+end_src *** Updating Some day you might want to update this package via ~git pull~ and then reinstall it. Sometimes this may fail, especially if Lisp-Macros are involved and the version hasn't changed. To avoid this kind of problems, you should delete the old package via ~list-packages~, restart Emacs and then reinstall the package. This also applies when updating via package and melpa. ** Known problems :PROPERTIES: :CUSTOM_ID: known-problems :END: *** linum-mode PDF Tools does not work well together with ~linum-mode~ and activating it in a ~pdf-view-mode~, e.g. via ~global-linum-mode~, might make Emacs choke. *** auto-revert Autorevert works by polling the file-system every ~auto-revert-interval~ seconds, optionally combined with some event-based reverting via [[https://www.gnu.org/software/emacs/manual/html_node/elisp/File-Notifications.html][file notification]]. But this currently does not work reliably, such that Emacs may revert the PDF-buffer while the corresponding file is still being written to (e.g. by LaTeX), leading to a potential error.

(Warnings, however, are ignored) # # ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on # success/failure. # # If EXTRA-FLAGS is defined, it is added to the current language's default # flags (e.g. CFLAGS) when the check is done. The check is thus made with # the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to # force the compiler to issue an error when a bad flag is given. # # INPUT gives an alternative input source to AC_COMPILE_IFELSE. # # NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this # macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG. # # LICENSE # # Copyright (c) 2008 Guido U.

The Synchronization TeXnology named SyncTeX is a new feature of recent TeX engines designed by Jerome Laurens. It allows to synchronize between input and output, which means to navigate from the source document to the typeset material and vice versa. More informations on http://itexmac2.sourceforge.net/SyncTeX.html This package is mainly for developers, it mainly contains the following files: synctex_parser_readme.txt synctex_parser_version.txt synctex_parser_utils.c synctex_parser_utils.h synctex_parser_local.h synctex_parser.h synctex_parser.c The file you are reading contains more informations about the SyncTeX parser history. In order to support SyncTeX in a viewer, it is sufficient to include in the source the files synctex_parser.h and synctex_parser.c. The synctex parser usage is described in synctex_parser.h header file. The other files are used by tex engines or by the synctex command line utility: ChangeLog README.txt am man1 man5 synctex-common.h synctex-convert.sh synctex-e-mem.ch0 synctex-e-mem.ch1 synctex-e-rec.ch0 synctex-e-rec.ch1 synctex-etex.h synctex-mem.ch0 synctex-mem.ch1 synctex-mem.ch2 synctex-pdf-rec.ch2 synctex-pdftex.h synctex-rec.ch0 synctex-rec.ch1 synctex-rec.ch2 synctex-tex.h synctex-xe-mem.ch2 synctex-xe-rec.ch2 synctex-xe-rec.ch3 synctex-xetex.h synctex.c synctex.defines synctex.h synctex_main.c tests Version: -------- This is version 1, which refers to the synctex output file format. The files are identified by a build number. In order to help developers to automatically manage the version and build numbers and download the parser only when necessary, the synctex_parser.version is an ASCII text file just containing the current version and build numbers. History: -------- 1.1: Thu Jul 17 09:28:13 UTC 2008 - First official version available in TeXLive 2008 DVD. Unfortunately, the backwards synchronization is not working properly mainly for ConTeXt users, see below. 1.2: Tue Sep 2 10:28:32 UTC 2008 - Correction for ConTeXt support in the edit query. The previous method was assuming that TeX boxes do not overlap, which is reasonable for LaTeX but not for ConTeXt. This assumption is no longer considered. 1.3: Fri Sep 5 09:39:57 UTC 2008 - Local variable "read" renamed to "already_read" to avoid conflicts. - "inline" compiler directive renamed to "SYNCTEX_INLINE" for code support and maintenance - _synctex_error cannot be inlined due to variable arguments (thanks Christiaan Hofman) - Correction in the display query, extra boundary nodes are used for a more precise forwards synchronization 1.4: Fri Sep 12 08:12:34 UTC 2008 - For an unknown reason, the previous version was not the real 1.3 (as used in iTeXMac2 build 747). As a consequence, a crash was observed. - Some typos are fixed. 1.6: Mon Nov 3 20:20:02 UTC 2008 - The bug that prevented synchronization with compressed files on windows has been fixed. - New interface to allow system specific customization. - Note that some APIs have changed. 1.8: Mer 8 jul 2009 11:32:38 UTC Note that version 1.7 was delivered privately. - bug fix: synctex was causing a memory leak in pdftex and xetex, thus some processing speed degradation - bug fix: the synctex command line tool was broken when updating a .synctex file - enhancement: better accuracy of the synchronization process - enhancement: the pdf output file and the associated .synctex file no longer need to live in the same directory. The new -d option of the synctex command line tool manages this situation. This is handy when using something like tex -output-directory=DIR ... 1.9: Wed Nov 4 11:52:35 UTC 2009 - Various typo fixed - OutputDebugString replaced by OutputDebugStringA to deliberately disable unicode preprocessing - New conditional created because OutputDebugStringA is only available since Windows 2K professional 1.10: Sun Jan 10 10:12:32 UTC 2010 - Bug fix in synctex_parser.c to solve a synchronization problem with amsmath's gather environment. Concerns the synctex tool. 1.11: Sun Jan 17 09:12:31 UTC 2010 - Bug fix in synctex_parser.c, function synctex_node_box_visible_v: 'x' replaced by 'y'. Only 3rd party tools are concerned. 1.12: Mon Jul 19 21:52:10 UTC 2010 - Bug fix in synctex_parser.c, function __synctex_open: the io_mode was modified even in case of a non zero return, causing a void .synctex.gz file to be created even if it was not expected. Reported by Marek Kasik concerning a bug on evince. 1.13: Fri Mar 11 07:39:12 UTC 2011 - Bug fix in synctex_parser.c, better synchronization as suggested by Jan Sundermeyer (near line 3388). - Stronger code design in synctex_parser_utils.c, function _synctex_get_name (really neutral behavior). Only 3rd party tools are concerned. 1.14: Fri Apr 15 19:10:57 UTC 2011 - taking output_directory into account - Replaced FOPEN_WBIN_MODE by FOPEN_W_MODE when opening the text version of the .synctex file. - Merging with LuaTeX's version of synctex.c 1.15: Fri Jun 10 14:10:17 UTC 2011 This concerns the synctex command line tool and 3rd party developers. TeX and friends are not concerned by these changes. - Bug fixed in _synctex_get_io_mode_name, sometimes the wrong mode was returned - Support for LuaTeX convention of './' file prefixing 1.16: Tue Jun 14 08:23:30 UTC 2011 This concerns the synctex command line tool and 3rd party developers. TeX and friends are not concerned by these changes. - Better forward search (thanks Jose Alliste) - Support for LuaTeX convention of './' file prefixing now for everyone, not only for Windows 1.17: Fri Oct 14 08:15:16 UTC 2011 This concerns the synctex command line tool and 3rd party developers. TeX and friends are not concerned by these changes. - synctex_parser.c: cosmetic changes to enhance code readability - Better forward synchronization. The problem occurs for example with LaTeX \item command. The fact is that this command creates nodes at parse time but these nodes are used only after the text material of the \item is displayed on the page. The consequence is that sometimes, forward synchronization spots an irrelevant point from the point of view of the editing process. This was due to some very basic filtering policy, where a somehow arbitrary choice was made when many different possibilities where offered for synchronisation. Now, forward synchronization prefers nodes inside an hbox with as many acceptable spots as possible. This is achieved with the notion of mean line and node weight. - Adding support for the new file naming convention with './' + function synctex_ignore_leading_dot_slash_in_path replaces synctex_ignore_leading_dot_slash + function _synctex_is_equivalent_file_name is more permissive Previously, the function synctex_scanner_get_tag would give an answer only when the given file name was EXACTLY one of the file names listed in the synctex file. The we added some changes accepting for example 'foo.tex' instead of './foo.tex'. Now we have an even looser policy for dealing with file names. If the given file name does not match exactly one the file names of the synctex file, then we try to match the base names. If there is only one match of the base names, then it is taken as a match for the whole names. The base name is defined as following: ./foo => foo /my///.////foo => foo /foo => /foo /my//.foo => /my//.foo 1.17: Tue Mar 13 10:10:03 UTC 2012 - minor changes, no version changes - syntax man pages are fixed as suggested by M. Shimata see mail to tex-live@tug.org titled "syntax.5 has many warnings from groff" and "syntax.1 use invalid macro for mdoc" 1.17: Tue Jan 14 09:55:00 UTC 2014 - fixed a segfault, from Sebastian Ramacher 1.17: Mon Aug 04 - fixed a memory leak 1.18: Thu Jun 25 11:36:05 UTC 2015 - nested sheets now fully supported (does it make sense in TeX) - cosmetic changes: uniform indentation - suppression of warnings, mainly long/int ones. In short, zlib likes ints when size_t likes longs. - CLI synctex tool can build out of TeXLive (modulo appropriate options passed to the compiler) Acknowledgments: ---------------- The author received useful remarks from the pdfTeX developers, especially Hahn The Thanh, and significant help from XeTeX developer Jonathan Kew Nota Bene: ---------- If you include or use a significant part of the synctex package into a software, I would appreciate to be listed as contributor and see "SyncTeX" highlighted.
