10cgitrc - runtime configuration for cgit
11
12
13SYNOPSIS
14--------
15Cgitrc contains all runtime settings for cgit, including the list of git
16repositories, formatted as a line-separated list of NAME=VALUE pairs. Blank
17lines, and lines starting with '#', are ignored.
18
19
20LOCATION
21--------
22The default location of cgitrc, defined at compile time, is /etc/cgitrc. At
23runtime, cgit will consult the environment variable CGIT_CONFIG and, if
24defined, use its value instead.
25
26
27GLOBAL SETTINGS
28---------------
29about-filter::
30 Specifies a command which will be invoked to format the content of
31 about pages (both top-level and for each repository). The command will
32 get the content of the about-file on its STDIN, the name of the file
33 as the first argument, and the STDOUT from the command will be
34 included verbatim on the about page. Default value: none. See
35 also: "FILTER API".
36
37agefile::
38 Specifies a path, relative to each repository path, which can be used
39 to specify the date and time of the youngest commit in the repository.
40 The first line in the file is used as input to the "parse_date"
41 function in libgit. Recommended timestamp-format is "yyyy-mm-dd
42 hh:mm:ss". You may want to generate this file from a post-receive
43 hook. Default value: "info/web/last-modified".
44
45auth-filter::
46 Specifies a command that will be invoked for authenticating repository
47 access. Receives quite a few arguments, and data on both stdin and
48 stdout for authentication processing. Details follow later in this
49 document. If no auth-filter is specified, no authentication is
50 performed. Default value: none. See also: "FILTER API".

165 to expose this feature. If you use an alternate way of serving git
166 repositories, you may wish to disable this. Default value: "1".
167
168enable-index-links::
169 Flag which, when set to "1", will make cgit generate extra links for
170 each repo in the repository index (specifically, to the "summary",
171 "commit" and "tree" pages). Default value: "0".
172
173enable-index-owner::

203 "repo.enable-html-serving".
204
205enable-tree-linenumbers::
206 Flag which, when set to "1", will make cgit generate linenumber links

293 Set the mimetype for the specified filename extension. This is used
294 by the `plain` command when returning blob content.
295
296mimetype-file::
297 Specifies the file to use for automatic mimetype lookup. If specified
298 then this field is used as a fallback when no "mimetype.<ext>" match is
299 found. If unspecified then no such lookup is performed. The typical file
300 to use on a Linux system is /etc/mime.types. The format of the file must
301 comply to:

304 - a non-comment line starts with the mimetype (like image/png), followed
305 by one or more file extensions (like jpg), all separated by whitespace
306 Default value: none. See also: "mimetype.<ext>".
307
308module-link::
309 Text which will be used as the formatstring for a hyperlink when a
310 submodule is printed in a directory listing. The arguments for the
311 formatstring are the path and SHA1 of the submodule commit. Default
312 value: none.
313

330 config keys may be specified, and cgit will use the first found file
331 in this list. This is useful in conjunction with scan-path. Default
332 value: none. See also: scan-path, repo.readme.
333
334remove-suffix::
335 If set to "1" and scan-path is enabled, if any repositories are found
336 with a suffix of ".git", this suffix will be removed for the url and

366 "Git Repository Browser".
367
368scan-hidden-path::
369 If set to "1" and scan-path is enabled, scan-path will recurse into
370 directories whose name starts with a period ('.'). Otherwise,
371 scan-path will stay away from such directories (considered as
372 "hidden"). Note that this does not apply to the ".git" directory in
373 non-bare repos. This must be defined prior to scan-path.
374 Default value: 0. See also: scan-path.
375
376scan-path::
377 A path which will be scanned for repositories. If caching is enabled,
378 the result will be cached as a cgitrc include-file in the cache
379 directory. If project-list has been defined prior to scan-path,
380 scan-path loads only the directories listed in the file pointed to by
381 project-list. Be advised that only the global settings taken
382 before the scan-path directive will be applied to each repository.
383 Default value: none. See also: cache-scanrc-ttl, project-list,
384 "MACRO EXPANSION".
385
386section::
387 The name of the current repository section - all repositories defined
388 after this option will inherit the current section name. Default value:
389 none.
390
391section-sort::
392 Flag which, when set to "1", will sort the sections on the repository
393 listing by name. Set this flag to "0" if the order in the cgitrc file should
394 be preserved. Default value: "1". See also: section,
395 case-sensitive-sort, repository-sort.
396
397section-from-path::
398 A number which, if defined prior to scan-path, specifies how many
399 path elements from each repo path to use as a default section name.
400 If negative, cgit will discard the specified number of path elements
401 above the repo directory. Default value: "0".
402
403side-by-side-diffs::
404 If set to "1" shows side-by-side diffs instead of unidiffs per
405 default. Default value: "0".
406
407snapshots::
408 Text which specifies the default set of snapshot formats that cgit
409 generates links for. The value is a space-separated list of zero or

411 The special value "all" enables all snapshot formats.
412 Default value: none.
413
414source-filter::
415 Specifies a command which will be invoked to format plaintext blobs
416 in the tree view. The command will get the blob content on its STDIN
417 and the name of the blob as its only command line argument. The STDOUT
418 from the command will be included verbatim as the blob contents, i.e.
419 this can be used to implement e.g. syntax highlighting. Default value:
420 none. See also: "FILTER API".
421
422summary-branches::
423 Specifies the number of branches to display in the repository "summary"
424 view. Default value: "10".
425
426summary-log::
427 Specifies the number of log entries to display in the repository
428 "summary" view. Default value: "10".
429
430summary-tags::
431 Specifies the number of tags to display in the repository "summary"
432 view. Default value: "10".
433
434strict-export::
435 Filename which, if specified, needs to be present within the repository
436 for cgit to allow access to that repository. This can be used to emulate
437 gitweb's EXPORT_OK and STRICT_EXPORT functionality and limit cgit's
438 repositories to match those exported by git-daemon. This option must
439 be defined prior to scan-path.
440
441virtual-root::
442 Url which, if specified, will be used as root for all cgit links. It
443 will also cause cgit to generate 'virtual urls', i.e. urls like
444 '/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
445 value: none.
446 NOTE: cgit has recently learned how to use PATH_INFO to achieve the
447 same kind of virtual urls, so this option will probably be deprecated.

559 A value used to identify the owner of the repository. Default value:
560 none.
561
562repo.path::
563 An absolute path to the repository directory. For non-bare repositories
564 this is the .git-directory. Default value: none.
565
566repo.readme::
567 A path (relative to <repo.path>) which specifies a file to include
568 verbatim as the "About" page for this repo. You may also specify a
569 git refspec by head or by hash by prepending the refspec followed by
570 a colon. For example, "master:docs/readme.mkd". If the value begins
571 with a colon, i.e. ":docs/readme.rst", the default branch of the
572 repository will be used. Sharing any file will expose that entire
573 directory tree to the "/about/PATH" endpoints, so be sure that there
574 are no non-public files located in the same directory as the readme
575 file. Default value: <readme>.
576
577repo.snapshots::
578 A mask of snapshot formats for this repo that cgit generates links for,
579 restricted by the global "snapshots" setting. Default value:
580 <snapshots>.
581
582repo.snapshot-prefix::
583 Prefix to use for snapshot links instead of the repository basename.
584 For example, the "linux-stable" repository may wish to set this to
585 "linux" so that snapshots are in the format "linux-3.15.4" instead
586 of "linux-stable-3.15.4". Default value: <empty> meaning to use
587 the repository basename.
588
589repo.section::
590 Override the current section name for this repository. Default value:
591 none.
592
593repo.source-filter::
594 Override the default source-filter. Default value: none. See also:
595 "enable-filter-overrides". See also: "FILTER API".
596
597repo.url::
598 The relative url used to access the repository. This must be the first
599 setting specified for each repo. Default value: none.
600
601
602REPOSITORY-SPECIFIC CGITRC FILE
603-------------------------------
604When the option "scan-path" is used to auto-discover git repositories, cgit
605will try to parse the file "cgitrc" within any found repository. Such a
606repo-specific config file may contain any of the repo-specific options
607described above, except "repo.url" and "repo.path". Additionally, the "filter"
608options are only acknowledged in repo-specific config files when
609"enable-filter-overrides" is set to "1".
610
611Note: the "repo." prefix is dropped from the option names in repo-specific
612config files, e.g. "repo.desc" becomes "desc".
613
614
615FILTER API
616----------
617By default, filters are separate processes that are executed each time they
618are needed. Alternative technologies may be used by prefixing the filter
619specification with the relevant string; available values are:
620
621'exec:'::
622 The default "one process per filter" mode.
623
624'lua:'::
625 Executes the script using a built-in Lua interpreter. The script is
626 loaded once per execution of cgit, and may be called multiple times
627 during cgit's lifetime, making it a good choice for repeated filters
628 such as the 'email filter'. It responds to three functions:
629
630 'filter_open(argument1, argument2, argument3, ...)'::
631 This is called upon activation of the filter for a particular
632 set of data.
633 'filter_write(buffer)'::
634 This is called whenever cgit writes data to the webpage.
635 'filter_close()'::
636 This is called when the current filtering operation is
637 completed. It must return an integer value. Usually 0
638 indicates success.
639
640 Additionally, cgit exposes to the Lua the following built-in functions:
641
642 'html(str)'::
643 Writes 'str' to the webpage.
644 'html_txt(str)'::
645 HTML escapes and writes 'str' to the webpage.
646 'html_attr(str)'::
647 HTML escapes for an attribute and writes "str' to the webpage.
648 'html_url_path(str)'::
649 URL escapes for a path and writes 'str' to the webpage.
650 'html_url_arg(str)'::
651 URL escapes for an argument and writes 'str' to the webpage.
652 'html_include(file)'::
653 Includes 'file' in webpage.
654
655
656Parameters are provided to filters as follows.
657
658about filter::
659 This filter is given a single parameter: the filename of the source
660 file to filter. The filter can use the filename to determine (for
661 example) the type of syntax to follow when formatting the readme file.
662 The about text that is to be filtered is available on standard input
663 and the filtered text is expected on standard output.
664
665commit filter::
666 This filter is given no arguments. The commit message text that is to
667 be filtered is available on standard input and the filtered text is
668 expected on standard output.
669
670email filter::
671 This filter is given two parameters: the email address of the relevant
672 author and a string indicating the originating page. The filter will
673 then receive the text string to format on standard input and is
674 expected to write to standard output the formatted text to be included
675 in the page.
676
677owner filter::
678 This filter is given no arguments. The owner text is available on
679 standard input and the filter is expected to write to standard
680 output. The output is included in the Owner column.
681
682source filter::
683 This filter is given a single parameter: the filename of the source
684 file to filter. The filter can use the filename to determine (for
685 example) the syntax highlighting mode. The contents of the source
686 file that is to be filtered is available on standard input and the
687 filtered contents is expected on standard output.
688
689auth filter::
690 The authentication filter receives 12 parameters:
691 - filter action, explained below, which specifies which action the
692 filter is called for
693 - http cookie
694 - http method
695 - http referer
696 - http path
697 - http https flag
698 - cgit repo
699 - cgit page
700 - cgit url
701 - cgit login url
702 When the filter action is "body", this filter must write to output the
703 HTML for displaying the login form, which POSTs to the login url. When
704 the filter action is "authenticate-cookie", this filter must validate
705 the http cookie and return a 0 if it is invalid or 1 if it is invalid,
706 in the exit code / close function. If the filter action is
707 "authenticate-post", this filter receives POST'd parameters on
708 standard input, and should write a complete CGI response, preferably
709 with a 302 redirect, and write to output one or more "Set-Cookie"
710 HTTP headers, each followed by a newline.
711
712 Please see `filters/simple-authentication.lua` for a clear example
713 script that may be modified.
714
715
716All filters are handed the following environment variables:
717
718- CGIT_REPO_URL (from repo.url)
719- CGIT_REPO_NAME (from repo.name)
720- CGIT_REPO_PATH (from repo.path)
721- CGIT_REPO_OWNER (from repo.owner)
722- CGIT_REPO_DEFBRANCH (from repo.defbranch)
723- CGIT_REPO_SECTION (from repo.section)
724- CGIT_REPO_CLONE_URL (from repo.clone-url)
725
726If a setting is not defined for a repository and the corresponding global
727setting is also not defined (if applicable), then the corresponding
728environment variable will be unset.
729
730
731MACRO EXPANSION
732---------------
733The following cgitrc options support a simple macro expansion feature,
734where tokens prefixed with "$" are replaced with the value of a similarly
735named environment variable:
736
737- cache-root
738- include
739- project-list
740- scan-path
741
742Macro expansion will also happen on the content of $CGIT_CONFIG, if
743defined.
744
745One usage of this feature is virtual hosting, which in its simplest form
746can be accomplished by adding the following line to /etc/cgitrc:
747
748 include=/etc/cgitrc.d/$HTTP_HOST
749
750The following options are expanded during request processing, and support
751the environment variables defined in "FILTER API":
752
753- clone-url
754- repo.clone-url
755
756
757CACHE
758------
759
760All cache ttl values are in minutes. Negative ttl values indicate that a page
761type will never expire, and thus the first time a URL is accessed, the result
762will be cached indefinitely, even if the underlying git repository changes.
763Conversely, when a ttl value is zero, the cache is disabled for that
764particular page type, and the page type is never cached.
765
