 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".
 51

165	"scan-path", and must be defined prior, to augment repo-specific
166	settings. The keys gitweb.owner, gitweb.category, gitweb.description,
167	and gitweb.homepage will map to the cgit keys repo.owner, repo.section,
168	repo.desc, and repo.homepage respectively. All git config keys that begin
169	with "cgit." will be mapped to the corresponding "repo." key in cgit.
170	Default value: "0". See also: scan-path, section-from-path.
171
172enable-http-clone::
173	If set to "1", cgit will act as a dumb HTTP endpoint for git clones.
174	You can add "http://$HTTP_HOST$SCRIPT_NAME/$CGIT_REPO_URL" to clone-url
175	to expose this feature. If you use an alternate way of serving git
176	repositories, you may wish to disable this. Default value: "1".
177
178enable-html-serving::
179	Flag which, when set to "1", will allow the /plain handler to serve
180	mimetype headers that result in the file being treated as HTML by the
181	browser. When set to "0", such file types are returned instead as

285	by the `plain` command when returning blob content.
286
287mimetype-file::
288	Specifies the file to use for automatic mimetype lookup. If specified
289	then this field is used as a fallback when no "mimetype.<ext>" match is
290	found. If unspecified then no such lookup is performed. The typical file

311	on all pages. Default value: none. See also: "embedded".
312
313owner-filter::
314	Specifies a command which will be invoked to format the Owner
315	column of the main page.  The command will get the owner on STDIN,
316	and the STDOUT from the command will be included verbatim in the
317	table.  This can be used to link to additional context such as an
318	owners home page.  When active this filter is used instead of the
319	default owner query url.  Default value: none.
320	See also: "FILTER API".
321
322project-list::
323	A list of subdirectories inside of scan-path, relative to it, that
324	should loaded as git repositories. This must be defined prior to
325	scan-path. Default value: none. See also: scan-path, "MACRO

343	  `man git-diff`). Default value: "-1".
344
345repository-sort::
346	The way in which repositories in each section are sorted. Valid values
347	are "name" for sorting by the repo name or "age" for sorting by the
348	most recently updated repository. Default value: "name". See also:
349	section, case-sensitive-sort, section-sort.

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

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
410	more of the values "tar", "tar.gz", "tar.bz2", "tar.xz" and "zip".
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.
448

531	calculated url of the repository index page will be used. Default
532	value: global logo-link.
533
534repo.module-link::
535	Text which will be used as the formatstring for a hyperlink when a
536	submodule is printed in a directory listing. The arguments for the
537	formatstring are the path and SHA1 of the submodule commit. Default
538	value: <module-link>
539
540repo.module-link.<path>::
541	Text which will be used as the formatstring for a hyperlink when a
542	submodule with the specified subdirectory path is printed in a
543	directory listing. The only argument for the formatstring is the SHA1
544	of the submodule commit. Default value: none.
545
546repo.max-stats::
547	Override the default maximum statistics period. Valid values are equal
548	to the values specified for the global "max-stats" setting. Default
549	value: none.
550
551repo.name::
552	The value to show as repository name. Default value: <repo.url>.
553
554repo.owner::
555	A value used to identify the owner of the repository. Default value:
556	none.
557
558repo.owner-filter::
559	Override the default owner-filter. Default value: none. See also:
560	"enable-filter-overrides". See also: "FILTER API".
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.section::
578	Override the current section name for this repository. Default value:
579	none.
580
581repo.snapshots::
582	A mask of snapshot formats for this repo that cgit generates links for,
583	restricted by the global "snapshots" setting. Default value:
584	<snapshots>.
585
586repo.snapshot-prefix::
587	Prefix to use for snapshot links instead of the repository basename.
588	For example, the "linux-stable" repository may wish to set this to
589	"linux" so that snapshots are in the format "linux-3.15.4" instead
590	of "linux-stable-3.15.4".  Default value: <empty> meaning to use
591	the repository basename.
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
665auth filter::
666	The authentication filter receives 12 parameters:
667	  - filter action, explained below, which specifies which action the
668	    filter is called for
669	  - http cookie
670	  - http method
671	  - http referer
672	  - http path
673	  - http https flag
674	  - cgit repo
675	  - cgit page
676	  - cgit url
677	  - cgit login url
678	When the filter action is "body", this filter must write to output the
679	HTML for displaying the login form, which POSTs to the login url. When
680	the filter action is "authenticate-cookie", this filter must validate
681	the http cookie and return a 0 if it is invalid or 1 if it is invalid,
682	in the exit code / close function. If the filter action is
683	"authenticate-post", this filter receives POST'd parameters on
684	standard input, and should write a complete CGI response, preferably
685	with a 302 redirect, and write to output one or more "Set-Cookie"
686	HTTP headers, each followed by a newline.
687
688	Please see `filters/simple-authentication.lua` for a clear example
689	script that may be modified.
690
691commit filter::
692	This filter is given no arguments. The commit message text that is to
693	be filtered is available on standard input and the filtered text is
694	expected on standard output.
695
696email filter::
697	This filter is given two parameters: the email address of the relevant
698	author and a string indicating the originating page. The filter will
699	then receive the text string to format on standard input and is
700	expected to write to standard output the formatted text to be included
701	in the page.
702
703owner filter::
704	This filter is given no arguments.  The owner text is available on
705	standard input and the filter is expected to write to standard
706	output.  The output is included in the Owner column.
707
708source filter::
709	This filter is given a single parameter: the filename of the source
710	file to filter. The filter can use the filename to determine (for
711	example) the syntax highlighting mode. The contents of the source
712	file that is to be filtered is available on standard input and the
713	filtered contents is expected on standard output.
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
