 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

195	in commit view. Default value: "0". See also:
196	"repo.enable-subject-links".
197
198enable-html-serving::
199	Flag which, when set to "1", will allow the /plain handler to serve
200	mimetype headers that result in the file being treated as HTML by the

306	by the `plain` command when returning blob content.
307
308mimetype-file::
309	Specifies the file to use for automatic mimetype lookup. If specified

342	scan-path. Default value: none. See also: scan-path, "MACRO
343	EXPANSION".
344
345readme::
346	Text which will be used as default value for "repo.readme". Multiple

396
397scan-path::
398	A path which will be scanned for repositories. If caching is enabled,
399	the result will be cached as a cgitrc include-file in the cache
400	directory. If project-list has been defined prior to scan-path,
401	scan-path loads only the directories listed in the file pointed to by
402	project-list. Be advised that only the global settings taken
403	before the scan-path directive will be applied to each repository.
404	Default value: none. See also: cache-scanrc-ttl, project-list,
405	"MACRO EXPANSION".
406
407section::

422	above the repo directory. Default value: "0".
423
424side-by-side-diffs::
425	If set to "1" shows side-by-side diffs instead of unidiffs per
426	default. Default value: "0".
427

432	The special value "all" enables all snapshot formats.
433	Default value: none.
434
435source-filter::
436	Specifies a command which will be invoked to format plaintext blobs
437	in the tree view. The command will get the blob content on its STDIN
438	and the name of the blob as its only command line argument. The STDOUT
439	from the command will be included verbatim as the blob contents, i.e.
440	this can be used to implement e.g. syntax highlighting. Default value:
441	none. See also: "FILTER API".
442
443summary-branches::

453	view. Default value: "10".
454
455strict-export::
456	Filename which, if specified, needs to be present within the repository
457	for cgit to allow access to that repository. This can be used to emulate
458	gitweb's EXPORT_OK and STRICT_EXPORT functionality and limit cgit's
459	repositories to match those exported by git-daemon. This option must
460	be defined prior to scan-path.
461
462virtual-root::
463	Url which, if specified, will be used as root for all cgit links. It
464	will also cause cgit to generate 'virtual urls', i.e. urls like
465	'/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
466	value: none.
467	NOTE: cgit has recently learned how to use PATH_INFO to achieve the
468	same kind of virtual urls, so this option will probably be deprecated.

533	A flag which can be used to override the global setting
534	`enable-html-serving`. Default value: none.
535
536repo.hide::
537	Flag which, when set to "1", hides the repository from the repository
538	index. The repository can still be accessed by providing a direct path.
539	Default value: "0". See also: "repo.ignore".
540
541repo.ignore::
542	Flag which, when set to "1", ignores the repository. The repository
543	is not shown in the index and cannot be accessed by providing a direct
544	path. Default value: "0". See also: "repo.hide".
545
546repo.logo::
547	Url which specifies the source of an image which will be used as a logo
548	on this repo's pages. Default value: global logo.
549
550repo.logo-link::
551	Url loaded when clicking on the cgit logo image. If unspecified the
552	calculated url of the repository index page will be used. Default
553	value: global logo-link.
554
555repo.owner-filter::
556	Override the default owner-filter. Default value: none. See also:
557	"enable-filter-overrides". See also: "FILTER API".
558
559repo.module-link::
560	Text which will be used as the formatstring for a hyperlink when a
561	submodule is printed in a directory listing. The arguments for the
562	formatstring are the path and SHA1 of the submodule commit. Default
563	value: <module-link>
564
565repo.module-link.<path>::
566	Text which will be used as the formatstring for a hyperlink when a
567	submodule with the specified subdirectory path is printed in a
568	directory listing. The only argument for the formatstring is the SHA1
569	of the submodule commit. Default value: none.
570
571repo.max-stats::
572	Override the default maximum statistics period. Valid values are equal
573	to the values specified for the global "max-stats" setting. Default
574	value: none.
575
576repo.name::
577	The value to show as repository name. Default value: <repo.url>.
578
579repo.owner::
580	A value used to identify the owner of the repository. Default value:
581	none.
582
583repo.path::
584	An absolute path to the repository directory. For non-bare repositories
585	this is the .git-directory. Default value: none.
586
587repo.readme::
588	A path (relative to <repo.path>) which specifies a file to include
589	verbatim as the "About" page for this repo. You may also specify a
590	git refspec by head or by hash by prepending the refspec followed by
591	a colon. For example, "master:docs/readme.mkd". If the value begins
592	with a colon, i.e. ":docs/readme.rst", the default branch of the
593	repository will be used. Sharing any file will expose that entire
594	directory tree to the "/about/PATH" endpoints, so be sure that there
595	are no non-public files located in the same directory as the readme
596	file. Default value: <readme>.
597
598repo.snapshots::
599	A mask of snapshot formats for this repo that cgit generates links for,
600	restricted by the global "snapshots" setting. Default value:
601	<snapshots>.
602
603repo.snapshot-prefix::
604	Prefix to use for snapshot links instead of the repository basename.
605	For example, the "linux-stable" repository may wish to set this to
606	"linux" so that snapshots are in the format "linux-3.15.4" instead
607	of "linux-stable-3.15.4".  Default value: <empty> meaning to use
608	the repository basename.
609
610repo.section::
611	Override the current section name for this repository. Default value:
612	none.
613
614repo.source-filter::
615	Override the default source-filter. Default value: none. See also:
616	"enable-filter-overrides". See also: "FILTER API".
617
618repo.url::
619	The relative url used to access the repository. This must be the first
620	setting specified for each repo. Default value: none.
621
622
623REPOSITORY-SPECIFIC CGITRC FILE
624-------------------------------
625When the option "scan-path" is used to auto-discover git repositories, cgit
626will try to parse the file "cgitrc" within any found repository. Such a
627repo-specific config file may contain any of the repo-specific options
628described above, except "repo.url" and "repo.path". Additionally, the "filter"
629options are only acknowledged in repo-specific config files when
630"enable-filter-overrides" is set to "1".
631
632Note: the "repo." prefix is dropped from the option names in repo-specific
633config files, e.g. "repo.desc" becomes "desc".
634
635
636FILTER API
637----------
638By default, filters are separate processes that are executed each time they
639are needed.  Alternative technologies may be used by prefixing the filter
640specification with the relevant string; available values are:
641
642'exec:'::
643	The default "one process per filter" mode.
644
645'lua:'::
646	Executes the script using a built-in Lua interpreter. The script is
647	loaded once per execution of cgit, and may be called multiple times
648	during cgit's lifetime, making it a good choice for repeated filters
649	such as the 'email filter'. It responds to three functions:
650
651	'filter_open(argument1, argument2, argument3, ...)'::
652		This is called upon activation of the filter for a particular
653		set of data.
654	'filter_write(buffer)'::
655		This is called whenever cgit writes data to the webpage.
656	'filter_close()'::
657		This is called when the current filtering operation is
658		completed. It must return an integer value. Usually 0
659		indicates success.
660
661	Additionally, cgit exposes to the Lua the following built-in functions:
662
663	'html(str)'::
664		Writes 'str' to the webpage.
665	'html_txt(str)'::
666		HTML escapes and writes 'str' to the webpage.
667	'html_attr(str)'::
668		HTML escapes for an attribute and writes "str' to the webpage.
669	'html_url_path(str)'::
670		URL escapes for a path and writes 'str' to the webpage.
671	'html_url_arg(str)'::
672		URL escapes for an argument and writes 'str' to the webpage.
673	'html_include(file)'::
674		Includes 'file' in webpage.
675
676
677Parameters are provided to filters as follows.
678
679about filter::
680	This filter is given a single parameter: the filename of the source
681	file to filter. The filter can use the filename to determine (for
682	example) the type of syntax to follow when formatting the readme file.
683	The about text that is to be filtered is available on standard input
684	and the filtered text is expected on standard output.
685
686commit filter::
687	This filter is given no arguments. The commit message text that is to
688	be filtered is available on standard input and the filtered text is
689	expected on standard output.
690
691email filter::
692	This filter is given two parameters: the email address of the relevant
693	author and a string indicating the originating page. The filter will
694	then receive the text string to format on standard input and is
695	expected to write to standard output the formatted text to be included
696	in the page.
697
698owner filter::
699	This filter is given no arguments.  The owner text is available on
700	standard input and the filter is expected to write to standard
701	output.  The output is included in the Owner column.
702
703source filter::
704	This filter is given a single parameter: the filename of the source
705	file to filter. The filter can use the filename to determine (for
706	example) the syntax highlighting mode. The contents of the source
707	file that is to be filtered is available on standard input and the
708	filtered contents is expected on standard output.
709
710auth filter::
711	The authentication filter receives 12 parameters:
712	  - filter action, explained below, which specifies which action the
713	    filter is called for
714	  - http cookie
715	  - http method
716	  - http referer
717	  - http path
718	  - http https flag
719	  - cgit repo
720	  - cgit page
721	  - cgit url
722	  - cgit login url
723	When the filter action is "body", this filter must write to output the
724	HTML for displaying the login form, which POSTs to the login url. When
725	the filter action is "authenticate-cookie", this filter must validate
726	the http cookie and return a 0 if it is invalid or 1 if it is invalid,
727	in the exit code / close function. If the filter action is
728	"authenticate-post", this filter receives POST'd parameters on
729	standard input, and should write a complete CGI response, preferably
730	with a 302 redirect, and write to output one or more "Set-Cookie"
731	HTTP headers, each followed by a newline.
732
733	Please see `filters/simple-authentication.lua` for a clear example
734	script that may be modified.
735
736
737All filters are handed the following environment variables:
738
739- CGIT_REPO_URL (from repo.url)
740- CGIT_REPO_NAME (from repo.name)
741- CGIT_REPO_PATH (from repo.path)
742- CGIT_REPO_OWNER (from repo.owner)
743- CGIT_REPO_DEFBRANCH (from repo.defbranch)
744- CGIT_REPO_SECTION (from repo.section)
745- CGIT_REPO_CLONE_URL (from repo.clone-url)
746
747If a setting is not defined for a repository and the corresponding global
748setting is also not defined (if applicable), then the corresponding
749environment variable will be unset.
750
751
752MACRO EXPANSION
753---------------
754The following cgitrc options support a simple macro expansion feature,
755where tokens prefixed with "$" are replaced with the value of a similarly
756named environment variable:
757
758- cache-root
759- include
760- project-list
761- scan-path
762
763Macro expansion will also happen on the content of $CGIT_CONFIG, if
764defined.
765
766One usage of this feature is virtual hosting, which in its simplest form
767can be accomplished by adding the following line to /etc/cgitrc:
768
769	include=/etc/cgitrc.d/$HTTP_HOST
770
771The following options are expanded during request processing, and support
772the environment variables defined in "FILTER API":
773
774- clone-url
775- repo.clone-url
776
777
778CACHE
779------
780
781All cache ttl values are in minutes. Negative ttl values indicate that a page
782type will never expire, and thus the first time a URL is accessed, the result
783will be cached indefinitely, even if the underlying git repository changes.
784Conversely, when a ttl value is zero, the cache is disabled for that
785particular page type, and the page type is never cached.
786
