Changed all usages of this variable, + too. + (command): Test for individual KEY_* macros instead of TERMINFO + whenever one of the KEY_* macros is referenced. This should + reduce the TERMINFO mess a little. + + * src/find.c (read_block): Renamed from "readblock", to avoid name + clash with QNX system function of that name.

Does essentially the + same thing previously achieved by a rather more cryptic + postmsg(""). + (postfatal): New function to printout a fatal error message and + terminate the program. Works like posterr(), but exits curses + first, so the message should end up visible after the program + exits. Using this instead of posterr()+myexit() fixes SF bug + #419510. + (dispinit): Use postfatal:(). + (postmsg): Use clearmsg(). + (postmsg2): Call curses refresh() after change. + + * src/global.h: Add prototypes for new functions clearmsg() and + postfatal(). + + * src/find.c (putsource): Use postfatal(). + + * src/main.c (main, skiplist): Use postfatal() and clearmsg(). + + * src/command.c (command): Use clearmsg(). + + * src/build.c (build, seek_to_trailer, movefile): Use postfatal(). + + * src/alloc.c (alloctest): Use postfatal(). + + * src/display.c (jumpback): Re-instate signal handler, in an + attempt to fix problems reported with the general behaviour of + signal handlers in cscope. + + * src/scanner.l (ws, wsnl): Two new predefined patterns to catch + not only blanks and tabs, but all generally allowed white-space + characters in source files: form feeds, vertical tabs, carriage + returns. Replaced most occurence of [ \t] and [ \t\n] by these. + This is a back-port from fscanner.l.

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.

The +;; purpose of "cscope-indexer" is to create and optionally maintain +;; the cscope databases. If all of your source files are in one +;; directory, you don't need this script; it's very nice to have, +;; though, as it handles recursive subdirectory indexing, and can be +;; used in a nightly or weekly cron job to index very large source +;; repositories. See the beginning of the file, "cscope-indexer", for +;; usage information. +;; +;; Installation steps: +;; +;; 0. (It is, of course, assumed that cscope is already properly +;; installed on the current system.) +;; +;; 1. Install the "cscope-indexer" script into some convenient +;; directory in $PATH. The only real constraint is that (X)Emacs +;; must be able to find and execute it. You may also have to edit +;; the value of PATH in the script, although this is unlikely; the +;; majority of people should be able to use the script, "as-is". +;; +;; 2. Make sure that the "cscope-indexer" script is executable. In +;; particular, if you had to ftp this file, it is probably no +;; longer executable. +;; +;; 3. Put this emacs-lisp file somewhere where (X)Emacs can find it. It +;; basically has to be in some directory listed in "load-path". +;; +;; 4. Edit your ~/.emacs file to add the line: +;; +;; (require 'xcscope) +;; +;; 5. If you intend to use xcscope.el often you can optionally edit your +;; ~/.emacs file to add keybindings that reduce the number of keystrokes +;; required. For example, the following will add "C-f#" keybindings, which +;; are easier to type than the usual "C-c s" prefixed keybindings. Note +;; that specifying "global-map" instead of "cscope:map" makes the +;; keybindings available in all buffers: +;; +;; (define-key global-map [(control f3)] 'cscope-set-initial-directory) +;; (define-key global-map [(control f4)] 'cscope-unset-initial-directory) +;; (define-key global-map [(control f5)] 'cscope-find-this-symbol) +;; (define-key global-map [(control f6)] 'cscope-find-global-definition) +;; (define-key global-map [(control f7)] +;; 'cscope-find-global-definition-no-prompting) +;; (define-key global-map [(control f8)] 'cscope-pop-mark) +;; (define-key global-map [(control f9)] 'cscope-next-symbol) +;; (define-key global-map [(control f10)] 'cscope-next-file) +;; (define-key global-map [(control f11)] 'cscope-prev-symbol) +;; (define-key global-map [(control f12)] 'cscope-prev-file) +;; (define-key global-map [(meta f9)] 'cscope-display-buffer) +;; (defin-ekey global-map [(meta f10)] 'cscope-display-buffer-toggle) +;; +;; 6. Restart (X)Emacs. That's it. +;; +;; +;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; +;; +;; ***** USING THIS MODULE ***** +;; +;; * Basic usage: +;; +;; If all of your C/C++/lex/yacc source files are in the same +;; directory, you can just start using this module. If your files are +;; spread out over multiple directories, see "Advanced usage", below. +;; +;; Just edit a source file, and use the pull-down or pop-up (button 3) +;; menus to select one of: +;; +;; Find symbol +;; Find global definition +;; Find called functions +;; Find functions calling a function +;; Find text string +;; Find egrep pattern +;; Find a file +;; Find files #including a file +;; +;; The cscope database will be automatically created in the same +;; directory as the source files (assuming that you've never used +;; cscope before), and a buffer will pop-up displaying the results. +;; You can then use button 2 (the middle button) on the mouse to edit +;; the selected file, or you can move the text cursor over a selection +;; and press [Enter]. +;; +;; Hopefully, the interface should be fairly intuitive. +;; +;; +;; * Locating the cscope databases: +;; +;; This module will first use the variable, `cscope-database-regexps', +;; to search for a suitable database directory. If a database location +;; cannot be found using this variable then a search is begun at the +;; variable, `cscope-initial-directory', if set, or the current +;; directory otherwise. If the directory is not a cscope database +;; directory then the directory's parent, parent's parent, etc. is +;; searched until a cscope database directory is found, or the root +;; directory is reached. If the root directory is reached, the current +;; directory will be used. +;; +;; A cscope database directory is one in which EITHER a cscope database +;; file (e.g., "cscope.out") OR a cscope file list (e.g., +;; "cscope.files") exists. If only "cscope.files" exists, the +;; corresponding "cscope.out" will be automatically created by cscope +;; when a search is done. By default, the cscope database file is called +;; "cscope.out", but this can be changed (on a global basis) via the +;; variable, `cscope-database-file'. There is limited support for cscope +;; databases that are named differently than that given by +;; `cscope-database-file', using the variable, `cscope-database-regexps'. +;; +;; Note that the variable, `cscope-database-regexps', is generally not +;; needed, as the normal hierarchical database search is sufficient +;; for placing and/or locating the cscope databases. However, there +;; may be cases where it makes sense to place the cscope databases +;; away from where the source files are kept; in this case, this +;; variable is used to determine the mapping. One use for this +;; variable is when you want to share the database file with other +;; users; in this case, the database may be located in a directory +;; separate from the source files. +;; +;; Setting the variable, `cscope-initial-directory', is useful when a +;; search is to be expanded by specifying a cscope database directory +;; that is a parent of the directory that this module would otherwise +;; use. For example, consider a project that contains the following +;; cscope database directories: +;; +;; /users/jdoe/sources +;; /users/jdoe/sources/proj1 +;; /users/jdoe/sources/proj2 +;; +;; If a search is initiated from a .c file in /users/jdoe/sources/proj1 +;; then (assuming the variable, `cscope-database-regexps', is not set) +;; /users/jdoe/sources/proj1 will be used as the cscope data base directory. +;; Only matches in files in /users/jdoe/sources/proj1 will be found. This +;; can be remedied by typing "C-c s a" and then "M-del" to remove single +;; path element in order to use a cscope database directory of +;; /users/jdoe/sources. Normal searching can be restored by typing "C-c s A". +;; +;; +;; * Keybindings: +;; +;; All keybindings use the "C-c s" prefix, but are usable only while +;; editing a source file, or in the cscope results buffer: +;; +;; C-c s s Find symbol. +;; C-c s d Find global definition. +;; C-c s g Find global definition (alternate binding). +;; C-c s G Find global definition without prompting. +;; C-c s c Find functions calling a function. +;; C-c s C Find called functions (list functions called +;; from a function). +;; C-c s t Find text string. +;; C-c s e Find egrep pattern. +;; C-c s f Find a file. +;; C-c s i Find files #including a file. +;; +;; These pertain to navigation through the search results: +;; +;; C-c s b Display *cscope* buffer. +;; C-c s B Auto display *cscope* buffer toggle. +;; C-c s n Next symbol. +;; C-c s N Next file. +;; C-c s p Previous symbol. +;; C-c s P Previous file. +;; C-c s u Pop mark. +;; +;; These pertain to setting and unsetting the variable, +;; `cscope-initial-directory', (location searched for the cscope database +;; directory): +;; +;; C-c s a Set initial directory. +;; C-c s A Unset initial directory. +;; +;; These pertain to cscope database maintenance: +;; +;; C-c s L Create list of files to index. +;; C-c s I Create list and index. +;; C-c s E Edit list of files to index. +;; C-c s W Locate this buffer's cscope directory +;; ("W" --> "where"). +;; C-c s S Locate this buffer's cscope directory. +;; (alternate binding: "S" --> "show"). +;; C-c s T Locate this buffer's cscope directory. +;; (alternate binding: "T" --> "tell"). +;; C-c s D Dired this buffer's directory. +;; +;; +;; * Advanced usage: +;; +;; If the source files are spread out over multiple directories, +;; you've got a few choices: +;; +;; [ NOTE: you will need to have the script, "cscope-indexer", +;; properly installed in order for the following to work. ] +;; +;; 1. If all of the directories exist below a common directory +;; (without any extraneous, unrelated subdirectories), you can tell +;; this module to place the cscope database into the top-level, +;; common directory. This assumes that you do not have any cscope +;; databases in any of the subdirectories. If you do, you should +;; delete them; otherwise, they will take precedence over the +;; top-level database. +;; +;; If you do have cscope databases in any subdirectory, the +;; following instructions may not work right. +;; +;; It's pretty easy to tell this module to use a top-level, common +;; directory: +;; +;; a. Make sure that the menu pick, "Cscope/Index recursively", is +;; checked (the default value). +;; +;; b. Select the menu pick, "Cscope/Create list and index", and +;; specify the top-level directory. This will run the script, +;; "cscope-indexer", in the background, so you can do other +;; things if indexing takes a long time. A list of files to +;; index will be created in "cscope.files", and the cscope +;; database will be created in "cscope.out". +;; +;; Once this has been done, you can then use the menu picks +;; (described in "Basic usage", above) to search for symbols. +;; +;; Note, however, that, if you add or delete source files, you'll +;; have to either rebuild the database using the above procedure, +;; or edit the file, "cscope.files" to add/delete the names of the +;; source files. To edit this file, you can use the menu pick, +;; "Cscope/Edit list of files to index". +;; +;; +;; 2. If most of the files exist below a common directory, but a few +;; are outside, you can use the menu pick, "Cscope/Create list of +;; files to index", and specify the top-level directory. Make sure +;; that "Cscope/Index recursively", is checked before you do so, +;; though. You can then edit the list of files to index using the +;; menu pick, "Cscope/Edit list of files to index". Just edit the +;; list to include any additional source files not already listed. +;; +;; Once you've created, edited, and saved the list, you can then +;; use the menu picks described under "Basic usage", above, to +;; search for symbols. The first time you search, you will have to +;; wait a while for cscope to fully index the source files, though. +;; If you have a lot of source files, you may want to manually run +;; cscope to build the database: +;; +;; cd top-level-directory # or wherever +;; rm -f cscope.out # not always necessary +;; cscope -b +;; +;; +;; 3. If the source files are scattered in many different, unrelated +;; places, you'll have to manually create cscope.files and put a +;; list of all pathnames into it. Then build the database using: +;; +;; cd some-directory # wherever cscope.files exists +;; rm -f cscope.out # not always necessary +;; cscope -b +;; +;; Next, read the documentation for the variable, +;; "cscope-database-regexps", and set it appropriately, such that +;; the above-created cscope database will be referenced when you +;; edit a related source file. +;; +;; Once this has been done, you can then use the menu picks +;; described under "Basic usage", above, to search for symbols. +;; +;; +;; * Interesting configuration variables: +;; +;; "cscope-truncate-lines" +;; This is the value of `truncate-lines' to use in cscope +;; buffers; the default is the current setting of +;; `truncate-lines'. This variable exists because it can be +;; easier to read cscope buffers with truncated lines, while +;; other buffers do not have truncated lines. +;; +;; "cscope-use-relative-paths" +;; If non-nil, use relative paths when creating the list of files +;; to index. The path is relative to the directory in which the +;; cscope database will be created. If nil, absolute paths will +;; be used. Absolute paths are good if you plan on moving the +;; database to some other directory (if you do so, you'll +;; probably also have to modify `cscope-database-regexps'). +;; Absolute paths may also be good if you share the database file +;; with other users (you'll probably want to specify some +;; automounted network path for this). +;; +;; "cscope-index-recursively" +;; If non-nil, index files in the current directory and all +;; subdirectories. If nil, only files in the current directory +;; are indexed. This variable is only used when creating the +;; list of files to index, or when creating the list of files and +;; the corresponding cscope database. +;; +;; "cscope-name-line-width" +;; The width of the combined "function name:line number" field in +;; the cscope results buffer. If negative, the field is +;; left-justified. +;; +;; "cscope-do-not-update-database" +;; If non-nil, never check and/or update the cscope database when +;; searching. Beware of setting this to non-nil, as this will +;; disable automatic database creation, updating, and +;; maintenance. +;; +;; "cscope-display-cscope-buffer" +;; If non-nil, display the *cscope* buffer after each search +;; (default). This variable can be set in order to reduce the +;; number of keystrokes required to navigate through the matches. +;; +;; "cscope-database-regexps" +;; List to force directory-to-cscope-database mappings. +;; This is a list of `(REGEXP DBLIST [ DBLIST ... ])', where: +;; +;; REGEXP is a regular expression matched against the current buffer's +;; current directory. The current buffer is typically some source file, +;; and you're probably searching for some symbol in or related to this +;; file. Basically, this regexp is used to relate the current directory +;; to a cscope database. You need to start REGEXP with "^" if you want +;; to match from the beginning of the current directory. +;; +;; DBLIST is a list that contains one or more of: +;; +;; ( DBDIR ) +;; ( DBDIR ( OPTIONS ) ) +;; ( t ) +;; t +;; +;; Here, DBDIR is a directory (or a file) that contains a cscope +;; database. If DBDIR is a directory, then it is expected that the +;; cscope database, if present, has the filename given by the variable, +;; `cscope-database-file'; if DBDIR is a file, then DBDIR is the path +;; name to a cscope database file (which does not have to be the same as +;; that given by `cscope-database-file'). If only DBDIR is specified, +;; then that cscope database will be searched without any additional +;; cscope command-line options. If OPTIONS is given, then OPTIONS is a +;; list of strings, where each string is a separate cscope command-line +;; option. +;; +;; In the case of "( t )", this specifies that the search is to use the +;; normal hierarchical database search. This option is used to +;; explicitly search using the hierarchical database search either before +;; or after other cscope database directories. +;; +;; If "t" is specified (not inside a list), this tells the searching +;; mechanism to stop searching if a match has been found (at the point +;; where "t" is encountered). This is useful for those projects that +;; consist of many subprojects. You can specify the most-used +;; subprojects first, followed by a "t", and then followed by a master +;; cscope database directory that covers all subprojects. This will +;; cause the most-used subprojects to be searched first (hopefully +;; quickly), and the search will then stop if a match was found. If not, +;; the search will continue using the master cscope database directory. +;; +;; Here, `cscope-database-regexps' is generally not used, as the normal +;; hierarchical database search is sufficient for placing and/or locating +;; the cscope databases.

Next, searches will be done using the cscope database +;; directories, "/users/jdoe/sources/proj2", +;; "/users/jdoe/sources/proj3/mycscope.out", and +;; "/users/jdoe/sources/proj4". Note that, instead of the file, +;; "cscope.out", the file, "mycscope.out", will be used in the +;; directory "/users/jdoe/sources/proj3". +;; +;; 3. If a match was found, searching will stop. +;; +;; 4. If a match was not found, searching will be done using +;; "/some/master/directory", and the command-line options "-d" +;; and "-I/usr/local/include" will be passed to cscope. +;; +;; If the current buffer's directory matches the regexp, +;; "^/users/jdoe/sources/gnome", then the following search will be +;; done: +;; +;; The search will be done only using the directory, +;; "/master/gnome/database". The "-d" option will be passed to +;; cscope. +;; +;; If the current buffer's directory does not match any of the above +;; regexps, then only the normal hierarchical database search will be +;; done. +;; +;; +;; * Other notes: +;; +;; 1. The script, "cscope-indexer", uses a sed command to determine +;; what is and is not a C/C++/lex/yacc source file. It's idea of a +;; source file may not correspond to yours. +;; +;; 2. This module is called, "xcscope", because someone else has +;; already written a "cscope.el" (although it's quite old). +;; +;; +;; * KNOWN BUGS: +;; +;; 1. Cannot handle whitespace in directory or file names. +;; +;; 2. By default, colored faces are used to display results. If you happen +;; to use a black background, part of the results may be invisible +;; (because the foreground color may be black, too). There are at least +;; two solutions for this: +;; +;; 2a. Turn off colored faces, by setting `cscope-use-face' to `nil', +;; e.g.: +;; +;; (setq cscope-use-face nil) +;; +;; 2b. Explicitly set colors for the faces used by cscope. The faces +;; are: +;; +;; cscope-file-face +;; cscope-function-face +;; cscope-line-number-face +;; cscope-line-face +;; cscope-mouse-face +;; +;; The face most likely to cause problems (e.g., black-on-black +;; color) is `cscope-line-face'. +;; +;; 3. The support for cscope databases different from that specified by +;; `cscope-database-file' is quirky. If the file does not exist, it +;; will not be auto-created (unlike files names by +;; `cscope-database-file').

You can use this script +to just build a list of files, or it can be used to +build a list and database. This script is not used to +just build a database (skipping the list of files +step), as this can be simply done by just calling +"cscope -b". + +Normally, cscope will do its own indexing, but this +script can be used to force indexing. This is useful +if you need to recurse into subdirectories, or have +many files to index (you can run this script from a +cron job, during the night). It is especially useful +for large projects, which can contstantly have source +files added and deleted; by using this script, the +changing sources files are automatically handled. + +Currently, any paths containing "/CVS/" or "/RCS/" are +stripped out (ignored). + +.SH OPTIONS +.TP +.B \-f database_file +Specifies the cscope database file (default: cscope.out). + +.TP +.B \-i list_file +Specifies the name of the file into which the list of files +to index is placed (default: cscope.files). + +.TP +.B \-l +Suppress the generation/updating of the cscope database +file.

In either case, +.I cscope +searches the standard directories for #include files that it does not +find in the current directory. +.I cscope +uses a symbol cross-reference, called +cscope.out by default, to locate functions, function calls, macros, +variables, and preprocessor symbols in the files. +.PP +.I cscope +builds the symbol cross-reference the first time it is used on +the source files for the program being browsed. On a subsequent +invocation, +.I cscope +rebuilds the cross-reference only if a source file +has changed or the list of source files is different. When the +cross-reference is rebuilt, the data for the unchanged files are +copied from the old cross-reference, which makes rebuilding faster +than the initial build. +.SH OPTIONS +Some command line arguments can only occur as the the ony argument in +the execution of cscope. They cause the program to just print out +some output and exit immediately: +.TP +.B -h +View the long usage help display. +.TP +.B -V +Print on the first line of screen the version number of cscope. +.TP +.B --help +Same as +.B -h +.TP +.B --version +Same as +.B -V + +.PP +The following options can appear in any combination: +.TP +.B -b +Build the cross-reference only. +.TP +.B -C +Ignore letter case when searching. +.TP +.B -c +Use only ASCII characters in the cross-reference file, that is, +do not compress the data. +.TP +.B -d +Do not update the cross-reference. +.TP +.B -e +Suppress the -e command prompt between files. +.TP +.BI -F symfile +Read symbol reference lines from +.I symfile. +(A symbol reference +file is created by > and >>, and can also be read using the < +command, described under ``Issuing Subsequent Requests,'' +below.) +.TP +.BI -f reffile +Use +.I reffile +as the cross-reference file name instead of the default "cscope.out". +.TP +.BI -I incdir +Look in +.I incdir +(before looking in $INCDIR, the standard place +for header files, normally /usr/include) for any #include files +whose names do not begin with ``/'' and that are not specified +on the command line or in +.I namefile +below. (The #include files +may be specified with either double quotes or angle brackets.) +The incdir directory is searched in addition to the current +directory (which is searched first) and the standard list +(which is searched last). If more than one occurrence of -I +appears, the directories are searched in the order they appear +on the command line. +.TP +.BI -i namefile +Browse through all source files whose names are listed in +.I namefile +(file names separated by spaces, tabs, or new-lines) instead of the +default name list file, which is called cscope.files. If this option +is specified, cscope ignores any file names appearing on the command +line. The argument namefile can be set to ``-'' to accept a list of +files from the standard input. Filenames in the namefile that contain +whitespace have to be enclosed in "double quotes". Inside such quoted +filenames, any double-quote and backslash characters have to be +escaped by backslashes. +.TP +.B -k +``Kernel Mode'', turns off the use of the default include dir +(usually /usr/include) when building the database, since kernel +source trees generally do not use it. +.TP +.B -L +Do a single search with line-oriented output when used with the +-num pattern option. +.TP +.B -l +Line-oriented interface (see ``Line-Oriented Interface'' +below). +.TP +.BI -[ "0-9" ] pattern +Go to input field +.I num +(counting from 0) and find +.I pattern. +.TP +.BI -P path +Prepend +.I path +to relative file names in a pre-built cross-reference file so you do +not have to change to the directory where the cross-reference file was +built. This option is only valid with the -d option. +.TP +.BI -p n +Display the last +.I n +file path components instead of the default (1). Use +.I 0 +to not display the file name at all. +.TP +.B -q +Enable fast symbol lookup via an inverted index. This option +causes cscope to create 2 more files (default names +``cscope.in.out'' and ``cscope.po.out'') in addition to the normal +database. This allows a faster symbol search algorithm that +provides noticeably faster lookup performance for large projects. +.TP +.B -R +Recurse subdirectories during search for source files. +.TP +.BI -s dir +Look in +.I dir +for additional source files. This option is ignored if source files +are given on the command line. +.TP +.B -T +Use only the first eight characters to match against C symbols. +A regular expression containing special characters other than a +period (.) will not match any symbol if its minimum length is +greater than eight characters. +.TP +.B -U +Check file time stamps. This option will update the time stamp +on the database even if no files have changed. +.TP +.B -u +Unconditionally build the cross-reference file (assume that all +files have changed). +.TP +.B -v +Be more verbose in line-oriented mode.

Select the lines to be changed with these single-character +commands: +.PP +.TP +.B 0-9a-zA-Z +Mark or unmark the line to be changed. +.TP +.B * +Mark or unmark all displayed lines to be changed. +.TP +.B +Display next set of lines. +.TP +.B + +Display next set of lines. +.TP +.B - +Display previous set of lines. +.TP +.B a +Mark or unmark all lines to be changed. +.TP +.B ^d +Change the marked lines and exit. +.TP +.B +Exit without changing the marked lines. +.TP +.B ! +Start an interactive shell (type ^d to return to cscope). +.TP +.B ^l +Redraw the screen. +.TP +.B ? +Give help information about cscope commands. +.TP +.B Special keys +.PP +If your terminal has arrow keys that work in vi, you can use them +to move around the input fields. The up-arrow key is useful to move to +the previous +input field instead of using the key repeatedly. If you have +, , or keys they will act as the ^l, +, and - +commands, respectively. +.PP +.B Line-Oriented interface +.PP +The -l option lets you use cscope where a screen-oriented interface +would not be useful, for example, from another screen-oriented +program. +.PP +cscope will prompt with >> when it is ready for an input line starting +with the field number (counting from 0) immediately followed by the +search pattern, for example, ``lmain'' finds the definition of the +main function. +.PP +If you just want a single search, instead of the -l option use the -L +and -num pattern options, and you won't get the >> prompt. +.PP +For -l, cscope outputs the number of reference lines +cscope: 2 lines +.PP +For each reference found, cscope outputs a line consisting of the file +name, function name, line number, and line text, separated by spaces, +for example, +main.c main 161 main(argc, argv) +.PP +Note that the editor is not called to display a single reference, +unlike the screen-oriented interface. +.PP +You can use the c command to toggle ignore/use letter case when +searching. (When ignoring letter case, search for ``FILE'' will match +``File'' and ``file''.) +.PP +You can use the r command to rebuild the database. +.PP +cscope will quit when it detects end-of-file, or when the first +character of an input line is ``^d'' or ``q''. +.PP +.SH "ENVIRONMENT VARIABLES" +.TP +.B CSCOPE_EDITOR +Overrides the EDITOR and VIEWER variables. Use this if you wish to use +a different editor with cscope than that specified by your +EDITOR/VIEWER variables. +.TP +.B CSCOPE_LINEFLAG +Format of the line number flag for your editor. By default, cscope +invokes your editor via the equivalent of ``editor +N file'', where +``N'' is the line number that the editor should jump to. This format +is used by both emacs and vi. If your editor needs something +different, specify it in this variable, with ``%s'' as a placeholder +for the line number. Ex: if your editor needs to be invoked as +``editor -#103 file'' to go to line 103, set this variable to +``-#%s''. +.TP +.B CSCOPE_LINEFLAG_AFTER_FILE +Set this variable to ``yes'' if your editor needs to be invoked with +the line number option after the filename to be edited. To continue +the example from CSCOPE_LINEFLAG, above: if your editor needs to see +``editor file -#number'', set this environment variable. Users of most +standard editors (vi, emacs) do not need to set this variable. +.TP +.B EDITOR +Preferred editor, which defaults to vi. +.TP +.B HOME +Home directory, which is automatically set at login. +.TP +.B INCLUDEDIRS +Colon-separated list of directories to search for #include +files. +.TP +.B SHELL +Preferred shell, which defaults to sh. +.TP +.B SOURCEDIRS +Colon-separated list of directories to search for additional +source files. +.TP +.B TERM +Terminal type, which must be a screen terminal. +.TP +.B TERMINFO +Terminal information directory full path name. If your terminal +is not in the standard terminfo directory, see curses +and terminfo for how to make your own terminal description. +.TP +.B TMPDIR +Temporary file directory, which defaults to /var/tmp. +.TP +.B VIEWER +Preferred file display program (such as less), which overrides +EDITOR (see above). +.TP +.B VPATH +A colon-separated list of directories, each of which has the +same directory structure below it. If VPATH is set, cscope +searches for source files in the directories specified; if it +is not set, cscope searches only in the current directory. +.PP +.SH FILES +.TP +.B cscope.files +Default files containing -I, -p, -q, and -T options and the +list of source files (overridden by the -i option). +.TP +.B cscope.out +Symbol cross-reference file (overridden by the -f option), +which is put in the home directory if it cannot be created in +the current directory. +.TP +.PD 0 +.B cscope.in.out +.TP +.B cscope.po.out +.PD 1 +Default files containing the inverted index used for quick +symbol searching (-q option). If you use the -f option to +rename the cross-reference file (so it's not cscope.out), the +names for these inverted index files will be created by adding + .in and .po to the name you supply with -f. For example, if you +indicated -f xyz, then these files would be named xyz.in and +xyz.po. +.TP +.B INCDIR +Standard directory for #include files (usually /usr/include). +.SH Notices +.I cscope +recognizes function definitions of the form: +.PD 0 +.TP +fname blank ( args ) white arg_decs white { +.PD 1 +.TP +where: +.I fname +is the function name +.TP +.I blank +is zero or more spaces, tabs, vtabs, form feeds or carriage returns, +not including newlines +.TP +.I args +is any string that does not contain a ``"'' or a newline +.TP +.I white +is zero or more spaces, tabs, vtabs, form feeds, carriage returns or newlines +.TP +.I arg_decs +are zero or more argument declarations (arg_decs may include +comments and white space) +.PP +It is not necessary for a function declaration to start at the +beginning of a line.
