  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         The special value "all" enables all snapshot formats.
 433         Default value: none.
 434
 435 source-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
 443 summary-branches::
 444         Specifies the number of branches to display in the repository "summary"
 445         view. Default value: "10".
 446
 447 summary-log::
 448         Specifies the number of log entries to display in the repository
 449         "summary" view. Default value: "10".
 450
 451 summary-tags::
 452         Specifies the number of tags to display in the repository "summary"
 453         view. Default value: "10".
 454
 455 strict-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
 462 virtual-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.
 469

 540
 541 repo.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
 546 repo.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
 550 repo.logo-link::
 551         Url loaded when clicking on the cgit logo image. If unspecified the

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

 569         of the submodule commit. Default value: none.
 570
 571 repo.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
 576 repo.name::
 577         The value to show as repository name. Default value: <repo.url>.
 578
 579 repo.owner::
 580         A value used to identify the owner of the repository. Default value:
 581         none.
 582
 583 repo.path::
 584         An absolute path to the repository directory. For non-bare repositories
 585         this is the .git-directory. Default value: none.
 586
 587 repo.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
 598 repo.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
 603 repo.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
 610 repo.section::
 611         Override the current section name for this repository. Default value:
 612         none.
 613
 614 repo.source-filter::
 615         Override the default source-filter. Default value: none. See also:
 616         "enable-filter-overrides". See also: "FILTER API".
 617
 618 repo.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
 623 REPOSITORY-SPECIFIC CGITRC FILE
 624 -------------------------------
 625 When the option "scan-path" is used to auto-discover git repositories, cgit
 626 will try to parse the file "cgitrc" within any found repository. Such a
 627 repo-specific config file may contain any of the repo-specific options
 628 described above, except "repo.url" and "repo.path". Additionally, the "filter"
 629 options are only acknowledged in repo-specific config files when
 630 "enable-filter-overrides" is set to "1".
 631
 632 Note: the "repo." prefix is dropped from the option names in repo-specific
 633 config files, e.g. "repo.desc" becomes "desc".
 634
 635
 636 FILTER API
 637 ----------
 638 By default, filters are separate processes that are executed each time they
 639 are needed.  Alternative technologies may be used by prefixing the filter
 640 specification 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
 677 Parameters are provided to filters as follows.
 678
 679 about 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
 686 commit 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
 691 email 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
 698 owner 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
 703 source 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
 710 auth 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
 737 All 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
 747 If a setting is not defined for a repository and the corresponding global
 748 setting is also not defined (if applicable), then the corresponding
 749 environment variable will be unset.
 750
 751
 752 MACRO EXPANSION
 753 ---------------
 754 The following cgitrc options support a simple macro expansion feature,
 755 where tokens prefixed with "$" are replaced with the value of a similarly
 756 named environment variable:
 757
 758 - cache-root
 759 - include
 760 - project-list
 761 - scan-path
 762
 763 Macro expansion will also happen on the content of $CGIT_CONFIG, if
 764 defined.
 765
 766 One usage of this feature is virtual hosting, which in its simplest form
 767 can be accomplished by adding the following line to /etc/cgitrc:
 768
 769         include=/etc/cgitrc.d/$HTTP_HOST
 770
 771 The following options are expanded during request processing, and support
 772 the environment variables defined in "FILTER API":
 773
 774 - clone-url
 775 - repo.clone-url
 776
 777
 778 CACHE
 779 ------
 780
 781 All cache ttl values are in minutes. Negative ttl values indicate that a page
 782 type will never expire, and thus the first time a URL is accessed, the result
 783 will be cached indefinitely, even if the underlying git repository changes.
 784 Conversely, when a ttl value is zero, the cache is disabled for that
 785 particular page type, and the page type is never cached.
 786
