  10 cgitrc - runtime configuration for cgit
  11
  12
  13 SYNOPSIS
  14 --------
  15 Cgitrc contains all runtime settings for cgit, including the list of git
  16 repositories, formatted as a line-separated list of NAME=VALUE pairs. Blank
  17 lines, and lines starting with '#', are ignored.
  18
  19
  20 LOCATION
  21 --------
  22 The default location of cgitrc, defined at compile time, is /etc/cgitrc. At
  23 runtime, cgit will consult the environment variable CGIT_CONFIG and, if
  24 defined, use its value instead.
  25
  26
  27 GLOBAL SETTINGS
  28 ---------------
  29 about-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
  37 agefile::
  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
  45 auth-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".

  65
  66 cache-dynamic-ttl::
  67         Number which specifies the time-to-live, in minutes, for the cached
  68         version of repository pages accessed without a fixed SHA1. See also:
  69         "CACHE". Default value: "5".
  70

 116         The command will get the message on its STDIN, and the STDOUT from the
 117         command will be included verbatim as the commit message, i.e. this can
 118         be used to implement bugtracker integration. Default value: none.
 119         See also: "FILTER API".
 120
 121 commit-sort::
 122         Flag which, when set to "date", enables strict date ordering in the
 123         commit log, and when set to "topo" enables strict topological

 148
 149 enable-commit-graph::
 150         Flag which, when set to "1", will make cgit print an ASCII-art commit
 151         history graph to the left of the commit messages in the repository
 152         log page. Default value: "0".
 153
 154 enable-filter-overrides::
 155         Flag which, when set to "1", allows all filter settings to be
 156         overridden in repository-specific cgitrc files. Default value: none.
 157
 158 enable-follow-links::
 159         Flag which, when set to "1", allows users to follow a file in the log
 160         view.  Default value: "0".
 161
 162 enable-http-clone::
 163         If set to "1", cgit will act as an dumb HTTP endpoint for git clones.
 164         You can add "http://$HTTP_HOST$SCRIPT_NAME/$CGIT_REPO_URL" to clone-url
 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
 168 enable-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",

 200         mimetype headers that result in the file being treated as HTML by the
 201         browser. When set to "0", such file types are returned instead as
 202         text/plain or application/octet-stream. Default value: "0". See also:

 209 enable-git-config::
 210         Flag which, when set to "1", will allow cgit to use git config to set
 211         any repo specific settings. This option is used in conjunction with
 212         "scan-path", and must be defined prior, to augment repo-specific
 213         settings. The keys gitweb.owner, gitweb.category, gitweb.description,
 214         and gitweb.homepage will map to the cgit keys repo.owner, repo.section,
 215         repo.desc, and repo.homepage respectively. All git config keys that begin
 216         with "cgit." will be mapped to the corresponding "repo." key in cgit.
 217         Default value: "0". See also: scan-path, section-from-path.
 218
 219 favicon::
 220         Url used as link to a shortcut icon for cgit. It is suggested to use

 234         The content of the file specified with this option will be included
 235         verbatim at the top of all pages. Default value: none.
 236
 237 include::
 238         Name of a configfile to include before the rest of the current config-
 239         file is parsed. Default value: none. See also: "MACRO EXPANSION".
 240
 241 index-header::
 242         The content of the file specified with this option will be included
 243         verbatim above the repository index. This setting is deprecated, and
 244         will not be supported by cgit-1.0 (use root-readme instead). Default
 245         value: none.
 246
 247 index-info::
 248         The content of the file specified with this option will be included
 249         verbatim below the heading on the repository index page. This setting

 264         value: none.
 265
 266 owner-filter::
 267         Specifies a command which will be invoked to format the Owner
 268         column of the main page.  The command will get the owner on STDIN,
 269         and the STDOUT from the command will be included verbatim in the
 270         table.  This can be used to link to additional context such as an
 271         owners home page.  When active this filter is used instead of the
 272         default owner query url.  Default value: none.
 273         See also: "FILTER API".

 307
 308 mimetype-file::
 309         Specifies the file to use for automatic mimetype lookup. If specified
 310         then this field is used as a fallback when no "mimetype.<ext>" match is
 311         found. If unspecified then no such lookup is performed. The typical file
 312         to use on a Linux system is /etc/mime.types. The format of the file must
 313         comply to:
 314         - a comment line is an empty line or a line starting with a hash (#),
 315           optionally preceded by whitespace
 316         - a non-comment line starts with the mimetype (like image/png), followed
 317           by one or more file extensions (like jpg), all separated by whitespace
 318         Default value: none. See also: "mimetype.<ext>".
 319

 343         EXPANSION".
 344
 345 readme::
 346         Text which will be used as default value for "repo.readme". Multiple
 347         config keys may be specified, and cgit will use the first found file

 349         value: none. See also: scan-path, repo.readme.
 350
 351 remove-suffix::
 352         If set to "1" and scan-path is enabled, if any repositories are found
 353         with a suffix of ".git", this suffix will be removed for the url and
 354         name. This must be defined prior to scan-path. Default value: "0".
 355         See also: scan-path.
 356
 357 renamelimit::
 358         Maximum number of files to consider when detecting renames. The value

 387         "Git Repository Browser".
 388
 389 scan-hidden-path::
 390         If set to "1" and scan-path is enabled, scan-path will recurse into
 391         directories whose name starts with a period ('.'). Otherwise,
 392         scan-path will stay away from such directories (considered as
 393         "hidden"). Note that this does not apply to the ".git" directory in
 394         non-bare repos. This must be defined prior to scan-path.
 395         Default value: 0. See also: scan-path.
 396
 397 scan-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
 407 section::
 408         The name of the current repository section - all repositories defined
 409         after this option will inherit the current section name. Default value:
 410         none.
 411
 412 section-sort::
 413         Flag which, when set to "1", will sort the sections on the repository
 414         listing by name. Set this flag to "0" if the order in the cgitrc file should
 415         be preserved. Default value: "1". See also: section,
 416         case-sensitive-sort, repository-sort.
 417
 418 section-from-path::
 419         A number which, if defined prior to scan-path, specifies how many
 420         path elements from each repo path to use as a default section name.
 421         If negative, cgit will discard the specified number of path elements
 422         above the repo directory. Default value: "0".
 423
 424 side-by-side-diffs::
 425         If set to "1" shows side-by-side diffs instead of unidiffs per
 426         default. Default value: "0".
 427
 428 snapshots::
 429         Text which specifies the default set of snapshot formats that cgit
 430         generates links for. The value is a space-separated list of zero or
 431         more of the values "tar", "tar.gz", "tar.bz2", "tar.xz" and "zip".
 432         Default value: none.
 433
 434 source-filter::
 435         Specifies a command which will be invoked to format plaintext blobs
 436         in the tree view. The command will get the blob content on its STDIN
 437         and the name of the blob as its only command line argument. The STDOUT
 438         from the command will be included verbatim as the blob contents, i.e.
 439         this can be used to implement e.g. syntax highlighting. Default value:
 440         none. See also: "FILTER API".
 441
 442 summary-branches::
 443         Specifies the number of branches to display in the repository "summary"
 444         view. Default value: "10".
 445
 446 summary-log::
 447         Specifies the number of log entries to display in the repository
 448         "summary" view. Default value: "10".
 449
 450 summary-tags::
 451         Specifies the number of tags to display in the repository "summary"
 452         view. Default value: "10".
 453
 454 strict-export::
 455         Filename which, if specified, needs to be present within the repository
 456         for cgit to allow access to that repository. This can be used to emulate
 457         gitweb's EXPORT_OK and STRICT_EXPORT functionality and limit cgit's
 458         repositories to match those exported by git-daemon. This option must
 459         be defined prior to scan-path.
 460
 461 virtual-root::
 462         Url which, if specified, will be used as root for all cgit links. It
 463         will also cause cgit to generate 'virtual urls', i.e. urls like
 464         '/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
 465         value: none.
 466         NOTE: cgit has recently learned how to use PATH_INFO to achieve the
 467         same kind of virtual urls, so this option will probably be deprecated.
 468

 562         value: <module-link>
 563
 564 repo.module-link.<path>::
 565         Text which will be used as the formatstring for a hyperlink when a

 585
 586 repo.readme::
 587         A path (relative to <repo.path>) which specifies a file to include
 588         verbatim as the "About" page for this repo. You may also specify a
 589         git refspec by head or by hash by prepending the refspec followed by
 590         a colon. For example, "master:docs/readme.mkd". If the value begins
 591         with a colon, i.e. ":docs/readme.rst", the default branch of the
 592         repository will be used. Sharing any file will expose that entire
 593         directory tree to the "/about/PATH" endpoints, so be sure that there
 594         are no non-public files located in the same directory as the readme
 595         file. Default value: <readme>.
 596
 597 repo.snapshots::
 598         A mask of snapshot formats for this repo that cgit generates links for,

 607         Override the default source-filter. Default value: none. See also:
 608         "enable-filter-overrides". See also: "FILTER API".
 609
 610 repo.url::
 611         The relative url used to access the repository. This must be the first
 612         setting specified for each repo. Default value: none.
 613
 614
 615 REPOSITORY-SPECIFIC CGITRC FILE
 616 -------------------------------
 617 When the option "scan-path" is used to auto-discover git repositories, cgit
 618 will try to parse the file "cgitrc" within any found repository. Such a
 619 repo-specific config file may contain any of the repo-specific options
 620 described above, except "repo.url" and "repo.path". Additionally, the "filter"
 621 options are only acknowledged in repo-specific config files when
 622 "enable-filter-overrides" is set to "1".
 623
 624 Note: the "repo." prefix is dropped from the option names in repo-specific
 625 config files, e.g. "repo.desc" becomes "desc".
 626
 627
 628 FILTER API
 629 ----------
 630 By default, filters are separate processes that are executed each time they
 631 are needed.  Alternative technologies may be used by prefixing the filter
 632 specification with the relevant string; available values are:
 633
 634 'exec:'::
 635         The default "one process per filter" mode.
 636
 637 'lua:'::
 638         Executes the script using a built-in Lua interpreter. The script is
 639         loaded once per execution of cgit, and may be called multiple times
 640         during cgit's lifetime, making it a good choice for repeated filters
 641         such as the 'email filter'. It responds to three functions:
 642
 643         'filter_open(argument1, argument2, argument3, ...)'::
 644                 This is called upon activation of the filter for a particular
 645                 set of data.
 646         'filter_write(buffer)'::
 647                 This is called whenever cgit writes data to the webpage.
 648         'filter_close()'::
 649                 This is called when the current filtering operation is
 650                 completed. It must return an integer value. Usually 0
 651                 indicates success.
 652
 653         Additionally, cgit exposes to the Lua the following built-in functions:
 654
 655         'html(str)'::
 656                 Writes 'str' to the webpage.
 657         'html_txt(str)'::
 658                 HTML escapes and writes 'str' to the webpage.
 659         'html_attr(str)'::
 660                 HTML escapes for an attribute and writes "str' to the webpage.
 661         'html_url_path(str)'::
 662                 URL escapes for a path and writes 'str' to the webpage.
 663         'html_url_arg(str)'::
 664                 URL escapes for an argument and writes 'str' to the webpage.
 665         'html_include(file)'::
 666                 Includes 'file' in webpage.
 667
 668
 669 Parameters are provided to filters as follows.
 670
 671 about filter::
 672         This filter is given a single parameter: the filename of the source
 673         file to filter. The filter can use the filename to determine (for
 674         example) the type of syntax to follow when formatting the readme file.
 675         The about text that is to be filtered is available on standard input
 676         and the filtered text is expected on standard output.
 677
 678 commit filter::
 679         This filter is given no arguments. The commit message text that is to
 680         be filtered is available on standard input and the filtered text is
 681         expected on standard output.
 682
 683 email filter::
 684         This filter is given two parameters: the email address of the relevant
 685         author and a string indicating the originating page. The filter will
 686         then receive the text string to format on standard input and is
 687         expected to write to standard output the formatted text to be included
 688         in the page.
 689
 690 owner filter::
 691         This filter is given no arguments.  The owner text is available on
 692         standard input and the filter is expected to write to standard
 693         output.  The output is included in the Owner column.
 694
 695 source filter::
 696         This filter is given a single parameter: the filename of the source
 697         file to filter. The filter can use the filename to determine (for
 698         example) the syntax highlighting mode. The contents of the source
 699         file that is to be filtered is available on standard input and the
 700         filtered contents is expected on standard output.
 701
 702 auth filter::
 703         The authentication filter receives 12 parameters:
 704           - filter action, explained below, which specifies which action the
 705             filter is called for
 706           - http cookie
 707           - http method
 708           - http referer
 709           - http path
 710           - http https flag
 711           - cgit repo
 712           - cgit page
 713           - cgit url
 714           - cgit login url
 715         When the filter action is "body", this filter must write to output the
 716         HTML for displaying the login form, which POSTs to the login url. When
 717         the filter action is "authenticate-cookie", this filter must validate
 718         the http cookie and return a 0 if it is invalid or 1 if it is invalid,
 719         in the exit code / close function. If the filter action is
 720         "authenticate-post", this filter receives POST'd parameters on
 721         standard input, and should write a complete CGI response, preferably
 722         with a 302 redirect, and write to output one or more "Set-Cookie"
 723         HTTP headers, each followed by a newline.
 724
 725         Please see `filters/simple-authentication.lua` for a clear example
 726         script that may be modified.
 727
 728
 729 All filters are handed the following environment variables:
 730
 731 - CGIT_REPO_URL (from repo.url)
 732 - CGIT_REPO_NAME (from repo.name)
 733 - CGIT_REPO_PATH (from repo.path)
 734 - CGIT_REPO_OWNER (from repo.owner)
 735 - CGIT_REPO_DEFBRANCH (from repo.defbranch)
 736 - CGIT_REPO_SECTION (from repo.section)
 737 - CGIT_REPO_CLONE_URL (from repo.clone-url)
 738
 739 If a setting is not defined for a repository and the corresponding global
 740 setting is also not defined (if applicable), then the corresponding
 741 environment variable will be unset.
 742
 743
 744 MACRO EXPANSION
 745 ---------------
 746 The following cgitrc options support a simple macro expansion feature,
 747 where tokens prefixed with "$" are replaced with the value of a similarly
 748 named environment variable:
 749
 750 - cache-root
 751 - include
 752 - project-list
 753 - scan-path
 754
 755 Macro expansion will also happen on the content of $CGIT_CONFIG, if
 756 defined.
 757
 758 One usage of this feature is virtual hosting, which in its simplest form
 759 can be accomplished by adding the following line to /etc/cgitrc:
 760
 761         include=/etc/cgitrc.d/$HTTP_HOST
 762
 763 The following options are expanded during request processing, and support
 764 the environment variables defined in "FILTER API":
 765
 766 - clone-url
 767 - repo.clone-url
 768
 769
 770 CACHE
 771 ------
 772
 773 All cache ttl values are in minutes. Negative ttl values indicate that a page
 774 type will never expire, and thus the first time a URL is accessed, the result
 775 will be cached indefinitely, even if the underlying git repository changes.
 776 Conversely, when a ttl value is zero, the cache is disabled for that
 777 particular page type, and the page type is never cached.
 778
