  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

 140         Flag which, when set to "1", will make cgit generate a html fragment
 141         suitable for embedding in other html pages. Default value: none. See
 142         also: "noheader".
 143
 144 enable-commit-graph::
 145         Flag which, when set to "1", will make cgit print an ASCII-art commit
 146         history graph to the left of the commit messages in the repository

 156
 157 enable-http-clone::
 158         If set to "1", cgit will act as an dumb HTTP endpoint for git clones.
 159         You can add "http://$HTTP_HOST$SCRIPT_NAME/$CGIT_REPO_URL" to clone-url
 160         to expose this feature. If you use an alternate way of serving git
 161         repositories, you may wish to disable this. Default value: "1".
 162
 163 enable-index-links::
 164         Flag which, when set to "1", will make cgit generate extra links for
 165         each repo in the repository index (specifically, to the "summary",

 186
 187 enable-subject-links::
 188         Flag which, when set to "1", will make cgit use the subject of the
 189         parent commit as link text when generating links to parent commits
 190         in commit view. Default value: "0". See also:
 191         "repo.enable-subject-links".
 192

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

 222         The content of the file specified with this option will be included
 223         verbatim at the top of all pages. Default value: none.
 224
 225 include::
 226         Name of a configfile to include before the rest of the current config-
 227         file is parsed. Default value: none. See also: "MACRO EXPANSION".
 228
 229 index-header::
 230         The content of the file specified with this option will be included
 231         verbatim above the repository index. This setting is deprecated, and
 232         will not be supported by cgit-1.0 (use root-readme instead). Default
 233         value: none.
 234
 235 index-info::
 236         The content of the file specified with this option will be included
 237         verbatim below the heading on the repository index page. This setting
 238         is deprecated, and will not be supported by cgit-1.0 (use root-desc
 239         instead). Default value: none.
 240
 241 local-time::
 242         Flag which, if set to "1", makes cgit print commit and tag times in the

 252         value: none.
 253
 254 owner-filter::
 255         Specifies a command which will be invoked to format the Owner
 256         column of the main page.  The command will get the owner on STDIN,
 257         and the STDOUT from the command will be included verbatim in the
 258         table.  This can be used to link to additional context such as an
 259         owners home page.  When active this filter is used instead of the
 260         default owner query url.  Default value: none.
 261         See also: "FILTER API".
 262
 263 max-atom-items::

 295
 296 mimetype-file::
 297         Specifies the file to use for automatic mimetype lookup. If specified
 298         then this field is used as a fallback when no "mimetype.<ext>" match is
 299         found. If unspecified then no such lookup is performed. The typical file
 300         to use on a Linux system is /etc/mime.types. The format of the file must
 301         comply to:
 302         - a comment line is an empty line or a line starting with a hash (#),
 303           optionally preceded by whitespace
 304         - a non-comment line starts with the mimetype (like image/png), followed
 305           by one or more file extensions (like jpg), all separated by whitespace
 306         Default value: none. See also: "mimetype.<ext>".
 307
 308 module-link::
 309         Text which will be used as the formatstring for a hyperlink when a

 331         EXPANSION".
 332
 333 readme::
 334         Text which will be used as default value for "repo.readme". Multiple
 335         config keys may be specified, and cgit will use the first found file

 337         value: none. See also: scan-path, repo.readme.
 338
 339 remove-suffix::
 340         If set to "1" and scan-path is enabled, if any repositories are found
 341         with a suffix of ".git", this suffix will be removed for the url and
 342         name. This must be defined prior to scan-path. Default value: "0".
 343         See also: scan-path.
 344
 345 renamelimit::
 346         Maximum number of files to consider when detecting renames. The value
 347          "-1" uses the compiletime value in git (for further info, look at

 375         "Git Repository Browser".
 376
 377 scan-hidden-path::
 378         If set to "1" and scan-path is enabled, scan-path will recurse into
 379         directories whose name starts with a period ('.'). Otherwise,
 380         scan-path will stay away from such directories (considered as
 381         "hidden"). Note that this does not apply to the ".git" directory in
 382         non-bare repos. This must be defined prior to scan-path.
 383         Default value: 0. See also: scan-path.
 384
 385 scan-path::
 386         A path which will be scanned for repositories. If caching is enabled,
 387         the result will be cached as a cgitrc include-file in the cache
 388         directory. If project-list has been defined prior to scan-path,
 389         scan-path loads only the directories listed in the file pointed to by
 390         project-list. Be advised that only the global settings taken
 391         before the scan-path directive will be applied to each repository.
 392         Default value: none. See also: cache-scanrc-ttl, project-list,
 393         "MACRO EXPANSION".
 394
 395 section::
 396         The name of the current repository section - all repositories defined
 397         after this option will inherit the current section name. Default value:
 398         none.
 399
 400 section-sort::
 401         Flag which, when set to "1", will sort the sections on the repository
 402         listing by name. Set this flag to "0" if the order in the cgitrc file should
 403         be preserved. Default value: "1". See also: section,
 404         case-sensitive-sort, repository-sort.
 405
 406 section-from-path::
 407         A number which, if defined prior to scan-path, specifies how many
 408         path elements from each repo path to use as a default section name.
 409         If negative, cgit will discard the specified number of path elements
 410         above the repo directory. Default value: "0".
 411
 412 side-by-side-diffs::
 413         If set to "1" shows side-by-side diffs instead of unidiffs per
 414         default. Default value: "0".
 415
 416 snapshots::
 417         Text which specifies the default set of snapshot formats that cgit
 418         generates links for. The value is a space-separated list of zero or
 419         more of the values "tar", "tar.gz", "tar.bz2", "tar.xz" and "zip".
 420         Default value: none.
 421
 422 source-filter::
 423         Specifies a command which will be invoked to format plaintext blobs
 424         in the tree view. The command will get the blob content on its STDIN
 425         and the name of the blob as its only command line argument. The STDOUT
 426         from the command will be included verbatim as the blob contents, i.e.
 427         this can be used to implement e.g. syntax highlighting. Default value:
 428         none. See also: "FILTER API".
 429
 430 summary-branches::
 431         Specifies the number of branches to display in the repository "summary"
 432         view. Default value: "10".
 433
 434 summary-log::
 435         Specifies the number of log entries to display in the repository
 436         "summary" view. Default value: "10".
 437
 438 summary-tags::
 439         Specifies the number of tags to display in the repository "summary"
 440         view. Default value: "10".
 441
 442 strict-export::
 443         Filename which, if specified, needs to be present within the repository
 444         for cgit to allow access to that repository. This can be used to emulate
 445         gitweb's EXPORT_OK and STRICT_EXPORT functionality and limit cgit's
 446         repositories to match those exported by git-daemon. This option must
 447         be defined prior to scan-path.
 448
 449 virtual-root::
 450         Url which, if specified, will be used as root for all cgit links. It
 451         will also cause cgit to generate 'virtual urls', i.e. urls like
 452         '/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
 453         value: none.
 454         NOTE: cgit has recently learned how to use PATH_INFO to achieve the
 455         same kind of virtual urls, so this option will probably be deprecated.
 456

 543         value: <module-link>
 544
 545 repo.module-link.<path>::
 546         Text which will be used as the formatstring for a hyperlink when a

 566
 567 repo.readme::
 568         A path (relative to <repo.path>) which specifies a file to include
 569         verbatim as the "About" page for this repo. You may also specify a
 570         git refspec by head or by hash by prepending the refspec followed by
 571         a colon. For example, "master:docs/readme.mkd". If the value begins
 572         with a colon, i.e. ":docs/readme.rst", the default branch of the
 573         repository will be used. Sharing any file will expose that entire
 574         directory tree to the "/about/PATH" endpoints, so be sure that there
 575         are no non-public files located in the same directory as the readme
 576         file. Default value: <readme>.
 577
 578 repo.snapshots::

 590
 591 repo.url::
 592         The relative url used to access the repository. This must be the first
 593         setting specified for each repo. Default value: none.
 594
 595
 596 REPOSITORY-SPECIFIC CGITRC FILE
 597 -------------------------------
 598 When the option "scan-path" is used to auto-discover git repositories, cgit
 599 will try to parse the file "cgitrc" within any found repository. Such a
 600 repo-specific config file may contain any of the repo-specific options
 601 described above, except "repo.url" and "repo.path". Additionally, the "filter"
 602 options are only acknowledged in repo-specific config files when
 603 "enable-filter-overrides" is set to "1".
 604
 605 Note: the "repo." prefix is dropped from the option names in repo-specific
 606 config files, e.g. "repo.desc" becomes "desc".
 607
 608
 609 FILTER API
 610 ----------
 611 By default, filters are separate processes that are executed each time they
 612 are needed.  Alternative technologies may be used by prefixing the filter
 613 specification with the relevant string; available values are:
 614
 615 'exec:'::
 616         The default "one process per filter" mode.
 617
 618 'lua:'::
 619         Executes the script using a built-in Lua interpreter. The script is
 620         loaded once per execution of cgit, and may be called multiple times
 621         during cgit's lifetime, making it a good choice for repeated filters
 622         such as the 'email filter'. It responds to three functions:
 623
 624         'filter_open(argument1, argument2, argument3, ...)'::
 625                 This is called upon activation of the filter for a particular
 626                 set of data.
 627         'filter_write(buffer)'::
 628                 This is called whenever cgit writes data to the webpage.
 629         'filter_close()'::
 630                 This is called when the current filtering operation is
 631                 completed. It must return an integer value. Usually 0
 632                 indicates success.
 633
 634         Additionally, cgit exposes to the Lua the following built-in functions:
 635
 636         'html(str)'::
 637                 Writes 'str' to the webpage.
 638         'html_txt(str)'::
 639                 HTML escapes and writes 'str' to the webpage.
 640         'html_attr(str)'::
 641                 HTML escapes for an attribute and writes "str' to the webpage.
 642         'html_url_path(str)'::
 643                 URL escapes for a path and writes 'str' to the webpage.
 644         'html_url_arg(str)'::
 645                 URL escapes for an argument and writes 'str' to the webpage.
 646         'html_include(file)'::
 647                 Includes 'file' in webpage.
 648
 649
 650 Parameters are provided to filters as follows.
 651
 652 about filter::
 653         This filter is given a single parameter: the filename of the source
 654         file to filter. The filter can use the filename to determine (for
 655         example) the type of syntax to follow when formatting the readme file.
 656         The about text that is to be filtered is available on standard input
 657         and the filtered text is expected on standard output.
 658
 659 commit filter::
 660         This filter is given no arguments. The commit message text that is to
 661         be filtered is available on standard input and the filtered text is
 662         expected on standard output.
 663
 664 email filter::
 665         This filter is given two parameters: the email address of the relevent
 666         author and a string indicating the originating page. The filter will
 667         then receive the text string to format on standard input and is
 668         expected to write to standard output the formatted text to be included
 669         in the page.
 670
 671 owner filter::
 672         This filter is given no arguments.  The owner text is avilable on
 673         standard input and the filter is expected to write to standard
 674         output.  The output is included in the Owner column.
 675
 676 source filter::
 677         This filter is given a single parameter: the filename of the source
 678         file to filter. The filter can use the filename to determine (for
 679         example) the syntax highlighting mode. The contents of the source
 680         file that is to be filtered is available on standard input and the
 681         filtered contents is expected on standard output.
 682
 683 auth filter::
 684         The authentication filter receives 12 parameters:
 685           - filter action, explained below, which specifies which action the
 686             filter is called for
 687           - http cookie
 688           - http method
 689           - http referer
 690           - http path
 691           - http https flag
 692           - cgit repo
 693           - cgit page
 694           - cgit url
 695           - cgit login url
 696         When the filter action is "body", this filter must write to output the
 697         HTML for displaying the login form, which POSTs to the login url. When
 698         the filter action is "authenticate-cookie", this filter must validate
 699         the http cookie and return a 0 if it is invalid or 1 if it is invalid,
 700         in the exit code / close function. If the filter action is
 701         "authenticate-post", this filter receives POST'd parameters on
 702         standard input, and should write a complete CGI response, preferably
 703         with a 302 redirect, and write to output one or more "Set-Cookie"
 704         HTTP headers, each followed by a newline.
 705
 706         Please see `filters/simple-authentication.lua` for a clear example
 707         script that may be modified.
 708
 709
 710 All filters are handed the following environment variables:
 711
 712 - CGIT_REPO_URL (from repo.url)
 713 - CGIT_REPO_NAME (from repo.name)
 714 - CGIT_REPO_PATH (from repo.path)
 715 - CGIT_REPO_OWNER (from repo.owner)
 716 - CGIT_REPO_DEFBRANCH (from repo.defbranch)
 717 - CGIT_REPO_SECTION (from repo.section)
 718 - CGIT_REPO_CLONE_URL (from repo.clone-url)
 719
 720 If a setting is not defined for a repository and the corresponding global
 721 setting is also not defined (if applicable), then the corresponding
 722 environment variable will be unset.
 723
 724
 725 MACRO EXPANSION
 726 ---------------
 727 The following cgitrc options support a simple macro expansion feature,
 728 where tokens prefixed with "$" are replaced with the value of a similarly
 729 named environment variable:
 730
 731 - cache-root
 732 - include
 733 - project-list
 734 - scan-path
 735
 736 Macro expansion will also happen on the content of $CGIT_CONFIG, if
 737 defined.
 738
 739 One usage of this feature is virtual hosting, which in its simplest form
 740 can be accomplished by adding the following line to /etc/cgitrc:
 741
 742         include=/etc/cgitrc.d/$HTTP_HOST
 743
 744 The following options are expanded during request processing, and support
 745 the environment variables defined in "FILTER API":
 746
 747 - clone-url
 748 - repo.clone-url
 749
 750
 751 CACHE
 752 ------
 753
 754 All cache ttl values are in minutes. Negative ttl values indicate that a page
 755 type will never expire, and thus the first time a URL is accessed, the result
 756 will be cached indefinitely, even if the underlying git repository changes.
 757 Conversely, when a ttl value is zero, the cache is disabled for that
 758 particular page type, and the page type is never cached.
 759
