  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".
  51
  52 branch-sort::
  53         Flag which, when set to "age", enables date ordering in the branch ref
  54         list, and when set to "name" enables ordering by branch name. Default
  55         value: "name".
  56

  63         version of repository pages accessed with a fixed SHA1. Negative
  64         values have infinite ttl. Default value: -1".
  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. Negative
  69         values have infinite ttl. Default value: "5".
  70
  71 cache-repo-ttl::
  72         Number which specifies the time-to-live, in minutes, for the cached

  97         See also: repository-sort, section-sort.
  98
  99 clone-prefix::
 100         Space-separated list of common prefixes which, when combined with a
 101         repository url, generates valid clone urls for the repository. This
 102         setting is only used if `repo.clone-url` is unspecified. Default value:

 114         be used to implement bugtracker integration. Default value: none.
 115         See also: "FILTER API".
 116
 117 commit-sort::
 118         Flag which, when set to "date", enables strict date ordering in the
 119         commit log, and when set to "topo" enables strict topological

 121         value: unset.
 122
 123 css::
 124         Url which specifies the css document to include in all cgit pages.
 125         Default value: "/cgit.css".

 127 email-filter::
 128         Specifies a command which will be invoked to format names and email
 129         address of committers, authors, and taggers, as represented in various
 130         places throughout the cgit interface. This command will receive an
 131         email address and an origin page string as its command line arguments,
 132         and the text to format on STDIN. It is to write the formatted text back
 133         out onto STDOUT. Default value: none. See also: "FILTER API".

 148
 149 enable-http-clone::
 150         If set to "1", cgit will act as an dumb HTTP endpoint for git clones.
 151         You can add "http://$HTTP_HOST$SCRIPT_NAME/$CGIT_REPO_URL" to clone-url
 152         to expose this feature. If you use an alternate way of serving git
 153         repositories, you may wish to disable this. Default value: "1".
 154
 155 enable-index-links::
 156         Flag which, when set to "1", will make cgit generate extra links for
 157         each repo in the repository index (specifically, to the "summary",

 175         Flag which, when set to "1", will make cgit display remote branches
 176         in the summary and refs views. Default value: "0". See also:
 177         "repo.enable-remote-branches".
 178
 179 enable-subject-links::
 180         Flag which, when set to "1", will make cgit use the subject of the
 181         parent commit as link text when generating links to parent commits

 193         settings. The keys gitweb.owner, gitweb.category, and gitweb.description
 194         will map to the cgit keys repo.owner, repo.section, and repo.desc,
 195         respectively. All git config keys that begin with "cgit." will be mapped
 196         to the corresponding "repo." key in cgit. Default value: "0". See also:
 197         scan-path, section-from-path.
 198
 199 favicon::
 200         Url used as link to a shortcut icon for cgit. It is suggested to use
 201         the value "/favicon.ico" since certain browsers will ignore other
 202         values. Default value: "/favicon.ico".
 203
 204 footer::
 205         The content of the file specified with this option will be included

 225         value: none.
 226
 227 index-info::
 228         The content of the file specified with this option will be included
 229         verbatim below the heading on the repository index page. This setting

 320         value: none. See also: scan-path, repo.readme.
 321
 322 remove-suffix::
 323         If set to "1" and scan-path is enabled, if any repositories are found
 324         with a suffix of ".git", this suffix will be removed for the url and
 325         name. This must be defined prior to scan-path. Default value: "0".
 326         See also: scan-path.
 327
 328 renamelimit::
 329         Maximum number of files to consider when detecting renames. The value

 358         "Git Repository Browser".
 359
 360 scan-hidden-path::
 361         If set to "1" and scan-path is enabled, scan-path will recurse into
 362         directories whose name starts with a period ('.'). Otherwise,
 363         scan-path will stay away from such directories (considered as
 364         "hidden"). Note that this does not apply to the ".git" directory in
 365         non-bare repos. This must be defined prior to scan-path.
 366         Default value: 0. See also: scan-path.
 367
 368 scan-path::
 369         A path which will be scanned for repositories. If caching is enabled,
 370         the result will be cached as a cgitrc include-file in the cache
 371         directory. If project-list has been defined prior to scan-path,
 372         scan-path loads only the directories listed in the file pointed to by
 373         project-list. Be advised that only the global settings taken
 374         before the scan-path directive will be applied to each repository.
 375         Default value: none. See also: cache-scanrc-ttl, project-list,
 376         "MACRO EXPANSION".
 377
 378 section::
 379         The name of the current repository section - all repositories defined
 380         after this option will inherit the current section name. Default value:
 381         none.
 382
 383 section-sort::
 384         Flag which, when set to "1", will sort the sections on the repository
 385         listing by name. Set this flag to "0" if the order in the cgitrc file should
 386         be preserved. Default value: "1". See also: section,
 387         case-sensitive-sort, repository-sort.
 388
 389 section-from-path::
 390         A number which, if defined prior to scan-path, specifies how many
 391         path elements from each repo path to use as a default section name.
 392         If negative, cgit will discard the specified number of path elements
 393         above the repo directory. Default value: "0".
 394
 395 side-by-side-diffs::
 396         If set to "1" shows side-by-side diffs instead of unidiffs per

 402         more of the values "tar", "tar.gz", "tar.bz2", "tar.xz" and "zip".
 403         Default value: none.
 404
 405 source-filter::
 406         Specifies a command which will be invoked to format plaintext blobs
 407         in the tree view. The command will get the blob content on its STDIN
 408         and the name of the blob as its only command line argument. The STDOUT
 409         from the command will be included verbatim as the blob contents, i.e.
 410         this can be used to implement e.g. syntax highlighting. Default value:
 411         none. See also: "FILTER API".
 412
 413 summary-branches::
 414         Specifies the number of branches to display in the repository "summary"
 415         view. Default value: "10".

 422         Specifies the number of tags to display in the repository "summary"
 423         view. Default value: "10".
 424
 425 strict-export::
 426         Filename which, if specified, needs to be present within the repository
 427         for cgit to allow access to that repository. This can be used to emulate
 428         gitweb's EXPORT_OK and STRICT_EXPORT functionality and limit cgit's
 429         repositories to match those exported by git-daemon. This option must
 430         be defined prior to scan-path.
 431
 432 virtual-root::
 433         Url which, if specified, will be used as root for all cgit links. It
 434         will also cause cgit to generate 'virtual urls', i.e. urls like
 435         '/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
 436         value: none.
 437         NOTE: cgit has recently learned how to use PATH_INFO to achieve the
 438         same kind of virtual urls, so this option will probably be deprecated.
 439

 509         Text which will be used as the formatstring for a hyperlink when a
 510         submodule is printed in a directory listing. The arguments for the
 511         formatstring are the path and SHA1 of the submodule commit. Default
 512         value: <module-link>
 513
 514 repo.module-link.<path>::
 515         Text which will be used as the formatstring for a hyperlink when a
 516         submodule with the specified subdirectory path is printed in a
 517         directory listing. The only argument for the formatstring is the SHA1
 518         of the submodule commit. Default value: none.

 535
 536 repo.readme::
 537         A path (relative to <repo.path>) which specifies a file to include
 538         verbatim as the "About" page for this repo. You may also specify a
 539         git refspec by head or by hash by prepending the refspec followed by
 540         a colon. For example, "master:docs/readme.mkd". If the value begins
 541         with a colon, i.e. ":docs/readme.rst", the default branch of the
 542         repository will be used. Sharing any file will expose that entire
 543         directory tree to the "/about/PATH" endpoints, so be sure that there
 544         are no non-public files located in the same directory as the readme
 545         file. Default value: <readme>.
 546

 562         setting specified for each repo. Default value: none.
 563
 564
 565 REPOSITORY-SPECIFIC CGITRC FILE
 566 -------------------------------
 567 When the option "scan-path" is used to auto-discover git repositories, cgit
 568 will try to parse the file "cgitrc" within any found repository. Such a
 569 repo-specific config file may contain any of the repo-specific options
 570 described above, except "repo.url" and "repo.path". Additionally, the "filter"
 571 options are only acknowledged in repo-specific config files when
 572 "enable-filter-overrides" is set to "1".
 573
 574 Note: the "repo." prefix is dropped from the option names in repo-specific
 575 config files, e.g. "repo.desc" becomes "desc".
 576
 577
 578 FILTER API
 579 ----------
 580 By default, filters are separate processes that are executed each time they
 581 are needed.  Alternative technologies may be used by prefixing the filter
 582 specification with the relevant string; available values are:
 583
 584 'exec:'::
 585         The default "one process per filter" mode.
 586
 587 'lua:'::
 588         Executes the script using a built-in Lua interpreter. The script is
 589         loaded once per execution of cgit, and may be called multiple times
 590         during cgit's lifetime, making it a good choice for repeated filters
 591         such as the 'email filter'. It responds to three functions:
 592
 593         'filter_open(argument1, argument2, argument3, ...)'::
 594                 This is called upon activation of the filter for a particular
 595                 set of data.
 596         'filter_write(buffer)'::
 597                 This is called whenever cgit writes data to the webpage.
 598         'filter_close()'::
 599                 This is called when the current filtering operation is
 600                 completed. It must return an integer value. Usually 0
 601                 indicates success.
 602
 603         Additionally, cgit exposes to the Lua the following built-in functions:
 604
 605         'html(str)'::
 606                 Writes 'str' to the webpage.
 607         'html_txt(str)'::
 608                 HTML escapes and writes 'str' to the webpage.
 609         'html_attr(str)'::
 610                 HTML escapes for an attribute and writes "str' to the webpage.
 611         'html_url_path(str)'::
 612                 URL escapes for a path and writes 'str' to the webpage.
 613         'html_url_arg(str)'::
 614                 URL escapes for an argument and writes 'str' to the webpage.
 615         'html_include(file)'::
 616                 Includes 'file' in webpage.
 617
 618
 619 Parameters are provided to filters as follows.
 620
 621 about filter::
 622         This filter is given a single parameter: the filename of the source
 623         file to filter. The filter can use the filename to determine (for
 624         example) the type of syntax to follow when formatting the readme file.
 625         The about text that is to be filtered is available on standard input
 626         and the filtered text is expected on standard output.
 627
 628 commit filter::
 629         This filter is given no arguments. The commit message text that is to
 630         be filtered is available on standard input and the filtered text is
 631         expected on standard output.
 632
 633 email filter::
 634         This filter is given two parameters: the email address of the relevent
 635         author and a string indicating the originating page. The filter will
 636         then receive the text string to format on standard input and is
 637         expected to write to standard output the formatted text to be included
 638         in the page.
 639
 640 source filter::
 641         This filter is given a single parameter: the filename of the source
 642         file to filter. The filter can use the filename to determine (for
 643         example) the syntax highlighting mode. The contents of the source
 644         file that is to be filtered is available on standard input and the
 645         filtered contents is expected on standard output.
 646
 647 auth filter::
 648         The authentication filter receives 12 parameters:
 649           - filter action, explained below, which specifies which action the
 650             filter is called for
 651           - http cookie
 652           - http method
 653           - http referer
 654           - http path
 655           - http https flag
 656           - cgit repo
 657           - cgit page
 658           - cgit url
 659           - cgit login url
 660         When the filter action is "body", this filter must write to output the
 661         HTML for displaying the login form, which POSTs to the login url. When
 662         the filter action is "authenticate-cookie", this filter must validate
 663         the http cookie and return a 0 if it is invalid or 1 if it is invalid,
 664         in the exit code / close function. If the filter action is
 665         "authenticate-post", this filter receives POST'd parameters on
 666         standard input, and should write a complete CGI request, preferably
 667         with a 302 redirect, and write to output one or more "Set-Cookie"
 668         HTTP headers, each followed by a newline.
 669
 670         Please see `filters/simple-authentication.lua` for a clear example
 671         script that may be modified.
 672
 673
 674 All filters are handed the following environment variables:
 675
 676 - CGIT_REPO_URL (from repo.url)
 677 - CGIT_REPO_NAME (from repo.name)
 678 - CGIT_REPO_PATH (from repo.path)
 679 - CGIT_REPO_OWNER (from repo.owner)
 680 - CGIT_REPO_DEFBRANCH (from repo.defbranch)
 681 - CGIT_REPO_SECTION (from repo.section)
 682 - CGIT_REPO_CLONE_URL (from repo.clone-url)
 683
 684 If a setting is not defined for a repository and the corresponding global
 685 setting is also not defined (if applicable), then the corresponding
 686 environment variable will be unset.
 687
 688
 689 MACRO EXPANSION
 690 ---------------
 691 The following cgitrc options support a simple macro expansion feature,
 692 where tokens prefixed with "$" are replaced with the value of a similarly
 693 named environment variable:
 694
 695 - cache-root
 696 - include
 697 - project-list
 698 - scan-path
 699
 700 Macro expansion will also happen on the content of $CGIT_CONFIG, if
 701 defined.
 702
 703 One usage of this feature is virtual hosting, which in its simplest form
 704 can be accomplished by adding the following line to /etc/cgitrc:
 705
 706         include=/etc/cgitrc.d/$HTTP_HOST
 707
 708 The following options are expanded during request processing, and support
 709 the environment variables defined in "FILTER API":
 710
 711 - clone-url
 712 - repo.clone-url
 713
