  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".

 133         address of committers, authors, and taggers, as represented in various
 134         places throughout the cgit interface. This command will receive an
 135         email address and an origin page string as its command line arguments,

 155         You can add "http://$HTTP_HOST$SCRIPT_NAME/$CGIT_REPO_URL" to clone-url
 156         to expose this feature. If you use an alternate way of serving git
 157         repositories, you may wish to disable this. Default value: "1".
 158
 159 enable-index-links::
 160         Flag which, when set to "1", will make cgit generate extra links for

 182
 183 enable-subject-links::
 184         Flag which, when set to "1", will make cgit use the subject of the
 185         parent commit as link text when generating links to parent commits

 197         settings. The keys gitweb.owner, gitweb.category, and gitweb.description
 198         will map to the cgit keys repo.owner, repo.section, and repo.desc,
 199         respectively. All git config keys that begin with "cgit." will be mapped
 200         to the corresponding "repo." key in cgit. Default value: "0". See also:
 201         scan-path, section-from-path.
 202
 203 favicon::
 204         Url used as link to a shortcut icon for cgit. It is suggested to use
 205         the value "/favicon.ico" since certain browsers will ignore other
 206         values. Default value: "/favicon.ico".
 207
 208 footer::
 209         The content of the file specified with this option will be included

 229         value: none.
 230
 231 index-info::
 232         The content of the file specified with this option will be included
 233         verbatim below the heading on the repository index page. This setting

 324         value: none. See also: scan-path, repo.readme.
 325
 326 remove-suffix::
 327         If set to "1" and scan-path is enabled, if any repositories are found
 328         with a suffix of ".git", this suffix will be removed for the url and
 329         name. This must be defined prior to scan-path. Default value: "0".
 330         See also: scan-path.
 331
 332 renamelimit::
 333         Maximum number of files to consider when detecting renames. The value

 362         "Git Repository Browser".
 363
 364 scan-hidden-path::
 365         If set to "1" and scan-path is enabled, scan-path will recurse into
 366         directories whose name starts with a period ('.'). Otherwise,
 367         scan-path will stay away from such directories (considered as
 368         "hidden"). Note that this does not apply to the ".git" directory in
 369         non-bare repos. This must be defined prior to scan-path.
 370         Default value: 0. See also: scan-path.
 371
 372 scan-path::
 373         A path which will be scanned for repositories. If caching is enabled,
 374         the result will be cached as a cgitrc include-file in the cache
 375         directory. If project-list has been defined prior to scan-path,
 376         scan-path loads only the directories listed in the file pointed to by
 377         project-list. Be advised that only the global settings taken
 378         before the scan-path directive will be applied to each repository.
 379         Default value: none. See also: cache-scanrc-ttl, project-list,
 380         "MACRO EXPANSION".
 381
 382 section::
 383         The name of the current repository section - all repositories defined
 384         after this option will inherit the current section name. Default value:
 385         none.
 386
 387 section-sort::
 388         Flag which, when set to "1", will sort the sections on the repository
 389         listing by name. Set this flag to "0" if the order in the cgitrc file should
 390         be preserved. Default value: "1". See also: section,
 391         case-sensitive-sort, repository-sort.
 392
 393 section-from-path::
 394         A number which, if defined prior to scan-path, specifies how many
 395         path elements from each repo path to use as a default section name.
 396         If negative, cgit will discard the specified number of path elements
 397         above the repo directory. Default value: "0".
 398
 399 side-by-side-diffs::
 400         If set to "1" shows side-by-side diffs instead of unidiffs per
 401         default. Default value: "0".

 406         more of the values "tar", "tar.gz", "tar.bz2", "tar.xz" and "zip".
 407         Default value: none.
 408
 409 source-filter::
 410         Specifies a command which will be invoked to format plaintext blobs
 411         in the tree view. The command will get the blob content on its STDIN
 412         and the name of the blob as its only command line argument. The STDOUT
 413         from the command will be included verbatim as the blob contents, i.e.
 414         this can be used to implement e.g. syntax highlighting. Default value:
 415         none. See also: "FILTER API".
 416
 417 summary-branches::
 418         Specifies the number of branches to display in the repository "summary"
 419         view. Default value: "10".
 420
 421 summary-log::
 422         Specifies the number of log entries to display in the repository
 423         "summary" view. Default value: "10".
 424
 425 summary-tags::
 426         Specifies the number of tags to display in the repository "summary"
 427         view. Default value: "10".
 428
 429 strict-export::
 430         Filename which, if specified, needs to be present within the repository
 431         for cgit to allow access to that repository. This can be used to emulate
 432         gitweb's EXPORT_OK and STRICT_EXPORT functionality and limit cgit's
 433         repositories to match those exported by git-daemon. This option must
 434         be defined prior to scan-path.
 435
 436 virtual-root::
 437         Url which, if specified, will be used as root for all cgit links. It
 438         will also cause cgit to generate 'virtual urls', i.e. urls like
 439         '/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
 440         value: none.
 441         NOTE: cgit has recently learned how to use PATH_INFO to achieve the
 442         same kind of virtual urls, so this option will probably be deprecated.
 443

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

 539
 540 repo.readme::
 541         A path (relative to <repo.path>) which specifies a file to include
 542         verbatim as the "About" page for this repo. You may also specify a
 543         git refspec by head or by hash by prepending the refspec followed by
 544         a colon. For example, "master:docs/readme.mkd". If the value begins
 545         with a colon, i.e. ":docs/readme.rst", the default branch of the
 546         repository will be used. Sharing any file will expose that entire
 547         directory tree to the "/about/PATH" endpoints, so be sure that there
 548         are no non-public files located in the same directory as the readme
 549         file. Default value: <readme>.
 550

 566         setting specified for each repo. Default value: none.
 567
 568
 569 REPOSITORY-SPECIFIC CGITRC FILE
 570 -------------------------------
 571 When the option "scan-path" is used to auto-discover git repositories, cgit
 572 will try to parse the file "cgitrc" within any found repository. Such a
 573 repo-specific config file may contain any of the repo-specific options
 574 described above, except "repo.url" and "repo.path". Additionally, the "filter"
 575 options are only acknowledged in repo-specific config files when
 576 "enable-filter-overrides" is set to "1".
 577
 578 Note: the "repo." prefix is dropped from the option names in repo-specific
 579 config files, e.g. "repo.desc" becomes "desc".
 580
 581
 582 FILTER API
 583 ----------
 584 By default, filters are separate processes that are executed each time they
 585 are needed.  Alternative technologies may be used by prefixing the filter
 586 specification with the relevant string; available values are:
 587
 588 'exec:'::
 589         The default "one process per filter" mode.
 590
 591 'lua:'::
 592         Executes the script using a built-in Lua interpreter. The script is
 593         loaded once per execution of cgit, and may be called multiple times
 594         during cgit's lifetime, making it a good choice for repeated filters
 595         such as the 'email filter'. It responds to three functions:
 596
 597         'filter_open(argument1, argument2, argument3, ...)'::
 598                 This is called upon activation of the filter for a particular
 599                 set of data.
 600         'filter_write(buffer)'::
 601                 This is called whenever cgit writes data to the webpage.
 602         'filter_close()'::
 603                 This is called when the current filtering operation is
 604                 completed. It must return an integer value. Usually 0
 605                 indicates success.
 606
 607         Additionally, cgit exposes to the Lua the following built-in functions:
 608
 609         'html(str)'::
 610                 Writes 'str' to the webpage.
 611         'html_txt(str)'::
 612                 HTML escapes and writes 'str' to the webpage.
 613         'html_attr(str)'::
 614                 HTML escapes for an attribute and writes "str' to the webpage.
 615         'html_url_path(str)'::
 616                 URL escapes for a path and writes 'str' to the webpage.
 617         'html_url_arg(str)'::
 618                 URL escapes for an argument and writes 'str' to the webpage.
 619         'html_include(file)'::
 620                 Includes 'file' in webpage.
 621
 622
 623 Parameters are provided to filters as follows.
 624
 625 about filter::
 626         This filter is given a single parameter: the filename of the source
 627         file to filter. The filter can use the filename to determine (for
 628         example) the type of syntax to follow when formatting the readme file.
 629         The about text that is to be filtered is available on standard input
 630         and the filtered text is expected on standard output.
 631
 632 commit filter::
 633         This filter is given no arguments. The commit message text that is to
 634         be filtered is available on standard input and the filtered text is
 635         expected on standard output.
 636
 637 email filter::
 638         This filter is given two parameters: the email address of the relevent
 639         author and a string indicating the originating page. The filter will
 640         then receive the text string to format on standard input and is
 641         expected to write to standard output the formatted text to be included
 642         in the page.
 643
 644 source filter::
 645         This filter is given a single parameter: the filename of the source
 646         file to filter. The filter can use the filename to determine (for
 647         example) the syntax highlighting mode. The contents of the source
 648         file that is to be filtered is available on standard input and the
 649         filtered contents is expected on standard output.
 650
 651 auth filter::
 652         The authentication filter receives 12 parameters:
 653           - filter action, explained below, which specifies which action the
 654             filter is called for
 655           - http cookie
 656           - http method
 657           - http referer
 658           - http path
 659           - http https flag
 660           - cgit repo
 661           - cgit page
 662           - cgit url
 663           - cgit login url
 664         When the filter action is "body", this filter must write to output the
 665         HTML for displaying the login form, which POSTs to the login url. When
 666         the filter action is "authenticate-cookie", this filter must validate
 667         the http cookie and return a 0 if it is invalid or 1 if it is invalid,
 668         in the exit code / close function. If the filter action is
 669         "authenticate-post", this filter receives POST'd parameters on
 670         standard input, and should write a complete CGI request, preferably
 671         with a 302 redirect, and write to output one or more "Set-Cookie"
 672         HTTP headers, each followed by a newline.
 673
 674         Please see `filters/simple-authentication.lua` for a clear example
 675         script that may be modified.
 676
 677
 678 All filters are handed the following environment variables:
 679
 680 - CGIT_REPO_URL (from repo.url)
 681 - CGIT_REPO_NAME (from repo.name)
 682 - CGIT_REPO_PATH (from repo.path)
 683 - CGIT_REPO_OWNER (from repo.owner)
 684 - CGIT_REPO_DEFBRANCH (from repo.defbranch)
 685 - CGIT_REPO_SECTION (from repo.section)
 686 - CGIT_REPO_CLONE_URL (from repo.clone-url)
 687
 688 If a setting is not defined for a repository and the corresponding global
 689 setting is also not defined (if applicable), then the corresponding
 690 environment variable will be unset.
 691
 692
 693 MACRO EXPANSION
 694 ---------------
 695 The following cgitrc options support a simple macro expansion feature,
 696 where tokens prefixed with "$" are replaced with the value of a similarly
 697 named environment variable:
 698
 699 - cache-root
 700 - include
 701 - project-list
 702 - scan-path
 703
 704 Macro expansion will also happen on the content of $CGIT_CONFIG, if
 705 defined.
 706
 707 One usage of this feature is virtual hosting, which in its simplest form
 708 can be accomplished by adding the following line to /etc/cgitrc:
 709
 710         include=/etc/cgitrc.d/$HTTP_HOST
 711
 712 The following options are expanded during request processing, and support
 713 the environment variables defined in "FILTER API":
 714
 715 - clone-url
 716 - repo.clone-url
 717
 718
 719 CACHE
 720 ------
 721
 722 All cache ttl values are in minutes. Negative ttl values indicate that a page
 723 type will never expire, and thus the first time a URL is accessed, the result
 724 will be cached indefinitely, even if the underlying git repository changes.
 725 Conversely, when a ttl value is zero, the cache is disabled for that
 726 particular page type, and the page type is never cached.
 727
