  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".

 146         history graph to the left of the commit messages in the repository
 147         log page. Default value: "0".
 148
 149 enable-filter-overrides::
 150         Flag which, when set to "1", allows all filter settings to be
 151         overridden in repository-specific cgitrc files. Default value: none.
 152
 153 enable-follow-links::
 154         Flag which, when set to "1", allows users to follow a file in the log
 155         view.  Default value: "0".
 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",
 166         "commit" and "tree" pages). Default value: "0".
 167
 168 enable-index-owner::

 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".

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

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

 229         The content of the file specified with this option will be included
 230         verbatim at the top of all pages. Default value: none.
 231
 232 include::
 233         Name of a configfile to include before the rest of the current config-
 234         file is parsed. Default value: none. See also: "MACRO EXPANSION".
 235
 236 index-header::
 237         The content of the file specified with this option will be included
 238         verbatim above the repository index. This setting is deprecated, and
 239         will not be supported by cgit-1.0 (use root-readme instead). Default
 240         value: none.
 241
 242 index-info::
 243         The content of the file specified with this option will be included
 244         verbatim below the heading on the repository index page. This setting

 255
 256 logo-link::
 257         Url loaded when clicking on the cgit logo image. If unspecified the
 258         calculated url of the repository index page will be used. Default
 259         value: none.
 260
 261 owner-filter::
 262         Specifies a command which will be invoked to format the Owner
 263         column of the main page.  The command will get the owner on STDIN,
 264         and the STDOUT from the command will be included verbatim in the
 265         table.  This can be used to link to additional context such as an
 266         owners home page.  When active this filter is used instead of the
 267         default owner query url.  Default value: none.
 268         See also: "FILTER API".

 302
 303 mimetype-file::
 304         Specifies the file to use for automatic mimetype lookup. If specified
 305         then this field is used as a fallback when no "mimetype.<ext>" match is
 306         found. If unspecified then no such lookup is performed. The typical file
 307         to use on a Linux system is /etc/mime.types. The format of the file must
 308         comply to:
 309         - a comment line is an empty line or a line starting with a hash (#),
 310           optionally preceded by whitespace
 311         - a non-comment line starts with the mimetype (like image/png), followed
 312           by one or more file extensions (like jpg), all separated by whitespace
 313         Default value: none. See also: "mimetype.<ext>".
 314
 315 module-link::
 316         Text which will be used as the formatstring for a hyperlink when a
 317         submodule is printed in a directory listing. The arguments for the

 338         EXPANSION".
 339
 340 readme::
 341         Text which will be used as default value for "repo.readme". Multiple
 342         config keys may be specified, and cgit will use the first found file
 343         in this list. This is useful in conjunction with scan-path. Default
 344         value: none. See also: scan-path, repo.readme.
 345
 346 remove-suffix::
 347         If set to "1" and scan-path is enabled, if any repositories are found
 348         with a suffix of ".git", this suffix will be removed for the url and
 349         name. This must be defined prior to scan-path. Default value: "0".
 350         See also: scan-path.
 351
 352 renamelimit::
 353         Maximum number of files to consider when detecting renames. The value
 354          "-1" uses the compiletime value in git (for further info, look at

 382         "Git Repository Browser".
 383
 384 scan-hidden-path::
 385         If set to "1" and scan-path is enabled, scan-path will recurse into
 386         directories whose name starts with a period ('.'). Otherwise,
 387         scan-path will stay away from such directories (considered as
 388         "hidden"). Note that this does not apply to the ".git" directory in
 389         non-bare repos. This must be defined prior to scan-path.
 390         Default value: 0. See also: scan-path.
 391
 392 scan-path::
 393         A path which will be scanned for repositories. If caching is enabled,
 394         the result will be cached as a cgitrc include-file in the cache
 395         directory. If project-list has been defined prior to scan-path,
 396         scan-path loads only the directories listed in the file pointed to by
 397         project-list. Be advised that only the global settings taken
 398         before the scan-path directive will be applied to each repository.
 399         Default value: none. See also: cache-scanrc-ttl, project-list,
 400         "MACRO EXPANSION".
 401
 402 section::
 403         The name of the current repository section - all repositories defined
 404         after this option will inherit the current section name. Default value:
 405         none.
 406
 407 section-sort::
 408         Flag which, when set to "1", will sort the sections on the repository
 409         listing by name. Set this flag to "0" if the order in the cgitrc file should
 410         be preserved. Default value: "1". See also: section,
 411         case-sensitive-sort, repository-sort.
 412
 413 section-from-path::
 414         A number which, if defined prior to scan-path, specifies how many
 415         path elements from each repo path to use as a default section name.
 416         If negative, cgit will discard the specified number of path elements
 417         above the repo directory. Default value: "0".
 418
 419 side-by-side-diffs::
 420         If set to "1" shows side-by-side diffs instead of unidiffs per
 421         default. Default value: "0".
 422
 423 snapshots::
 424         Text which specifies the default set of snapshot formats that cgit
 425         generates links for. The value is a space-separated list of zero or
 426         more of the values "tar", "tar.gz", "tar.bz2", "tar.xz" and "zip".
 427         Default value: none.
 428
 429 source-filter::
 430         Specifies a command which will be invoked to format plaintext blobs
 431         in the tree view. The command will get the blob content on its STDIN
 432         and the name of the blob as its only command line argument. The STDOUT
 433         from the command will be included verbatim as the blob contents, i.e.
 434         this can be used to implement e.g. syntax highlighting. Default value:
 435         none. See also: "FILTER API".
 436
 437 summary-branches::
 438         Specifies the number of branches to display in the repository "summary"
 439         view. Default value: "10".
 440
 441 summary-log::
 442         Specifies the number of log entries to display in the repository
 443         "summary" view. Default value: "10".
 444
 445 summary-tags::
 446         Specifies the number of tags to display in the repository "summary"
 447         view. Default value: "10".
 448
 449 strict-export::
 450         Filename which, if specified, needs to be present within the repository
 451         for cgit to allow access to that repository. This can be used to emulate
 452         gitweb's EXPORT_OK and STRICT_EXPORT functionality and limit cgit's
 453         repositories to match those exported by git-daemon. This option must
 454         be defined prior to scan-path.
 455
 456 virtual-root::
 457         Url which, if specified, will be used as root for all cgit links. It
 458         will also cause cgit to generate 'virtual urls', i.e. urls like
 459         '/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
 460         value: none.
 461         NOTE: cgit has recently learned how to use PATH_INFO to achieve the
 462         same kind of virtual urls, so this option will probably be deprecated.
 463

 557         value: <module-link>
 558
 559 repo.module-link.<path>::
 560         Text which will be used as the formatstring for a hyperlink when a

 580
 581 repo.readme::
 582         A path (relative to <repo.path>) which specifies a file to include
 583         verbatim as the "About" page for this repo. You may also specify a
 584         git refspec by head or by hash by prepending the refspec followed by
 585         a colon. For example, "master:docs/readme.mkd". If the value begins
 586         with a colon, i.e. ":docs/readme.rst", the default branch of the
 587         repository will be used. Sharing any file will expose that entire
 588         directory tree to the "/about/PATH" endpoints, so be sure that there
 589         are no non-public files located in the same directory as the readme
 590         file. Default value: <readme>.
 591
 592 repo.snapshots::

 604
 605 repo.url::
 606         The relative url used to access the repository. This must be the first
 607         setting specified for each repo. Default value: none.
 608
 609
 610 REPOSITORY-SPECIFIC CGITRC FILE
 611 -------------------------------
 612 When the option "scan-path" is used to auto-discover git repositories, cgit
 613 will try to parse the file "cgitrc" within any found repository. Such a
 614 repo-specific config file may contain any of the repo-specific options
 615 described above, except "repo.url" and "repo.path". Additionally, the "filter"
 616 options are only acknowledged in repo-specific config files when
 617 "enable-filter-overrides" is set to "1".
 618
 619 Note: the "repo." prefix is dropped from the option names in repo-specific
 620 config files, e.g. "repo.desc" becomes "desc".
 621
 622
 623 FILTER API
 624 ----------
 625 By default, filters are separate processes that are executed each time they
 626 are needed.  Alternative technologies may be used by prefixing the filter
 627 specification with the relevant string; available values are:
 628
 629 'exec:'::
 630         The default "one process per filter" mode.
 631
 632 'lua:'::
 633         Executes the script using a built-in Lua interpreter. The script is
 634         loaded once per execution of cgit, and may be called multiple times
 635         during cgit's lifetime, making it a good choice for repeated filters
 636         such as the 'email filter'. It responds to three functions:
 637
 638         'filter_open(argument1, argument2, argument3, ...)'::
 639                 This is called upon activation of the filter for a particular
 640                 set of data.
 641         'filter_write(buffer)'::
 642                 This is called whenever cgit writes data to the webpage.
 643         'filter_close()'::
 644                 This is called when the current filtering operation is
 645                 completed. It must return an integer value. Usually 0
 646                 indicates success.
 647
 648         Additionally, cgit exposes to the Lua the following built-in functions:
 649
 650         'html(str)'::
 651                 Writes 'str' to the webpage.
 652         'html_txt(str)'::
 653                 HTML escapes and writes 'str' to the webpage.
 654         'html_attr(str)'::
 655                 HTML escapes for an attribute and writes "str' to the webpage.
 656         'html_url_path(str)'::
 657                 URL escapes for a path and writes 'str' to the webpage.
 658         'html_url_arg(str)'::
 659                 URL escapes for an argument and writes 'str' to the webpage.
 660         'html_include(file)'::
 661                 Includes 'file' in webpage.
 662
 663
 664 Parameters are provided to filters as follows.
 665
 666 about filter::
 667         This filter is given a single parameter: the filename of the source
 668         file to filter. The filter can use the filename to determine (for
 669         example) the type of syntax to follow when formatting the readme file.
 670         The about text that is to be filtered is available on standard input
 671         and the filtered text is expected on standard output.
 672
 673 commit filter::
 674         This filter is given no arguments. The commit message text that is to
 675         be filtered is available on standard input and the filtered text is
 676         expected on standard output.
 677
 678 email filter::
 679         This filter is given two parameters: the email address of the relevant
 680         author and a string indicating the originating page. The filter will
 681         then receive the text string to format on standard input and is
 682         expected to write to standard output the formatted text to be included
 683         in the page.
 684
 685 owner filter::
 686         This filter is given no arguments.  The owner text is available on
 687         standard input and the filter is expected to write to standard
 688         output.  The output is included in the Owner column.
 689
 690 source filter::
 691         This filter is given a single parameter: the filename of the source
 692         file to filter. The filter can use the filename to determine (for
 693         example) the syntax highlighting mode. The contents of the source
 694         file that is to be filtered is available on standard input and the
 695         filtered contents is expected on standard output.
 696
 697 auth filter::
 698         The authentication filter receives 12 parameters:
 699           - filter action, explained below, which specifies which action the
 700             filter is called for
 701           - http cookie
 702           - http method
 703           - http referer
 704           - http path
 705           - http https flag
 706           - cgit repo
 707           - cgit page
 708           - cgit url
 709           - cgit login url
 710         When the filter action is "body", this filter must write to output the
 711         HTML for displaying the login form, which POSTs to the login url. When
 712         the filter action is "authenticate-cookie", this filter must validate
 713         the http cookie and return a 0 if it is invalid or 1 if it is invalid,
 714         in the exit code / close function. If the filter action is
 715         "authenticate-post", this filter receives POST'd parameters on
 716         standard input, and should write a complete CGI response, preferably
 717         with a 302 redirect, and write to output one or more "Set-Cookie"
 718         HTTP headers, each followed by a newline.
 719
 720         Please see `filters/simple-authentication.lua` for a clear example
 721         script that may be modified.
 722
 723
 724 All filters are handed the following environment variables:
 725
 726 - CGIT_REPO_URL (from repo.url)
 727 - CGIT_REPO_NAME (from repo.name)
 728 - CGIT_REPO_PATH (from repo.path)
 729 - CGIT_REPO_OWNER (from repo.owner)
 730 - CGIT_REPO_DEFBRANCH (from repo.defbranch)
 731 - CGIT_REPO_SECTION (from repo.section)
 732 - CGIT_REPO_CLONE_URL (from repo.clone-url)
 733
 734 If a setting is not defined for a repository and the corresponding global
 735 setting is also not defined (if applicable), then the corresponding
 736 environment variable will be unset.
 737
 738
 739 MACRO EXPANSION
 740 ---------------
 741 The following cgitrc options support a simple macro expansion feature,
 742 where tokens prefixed with "$" are replaced with the value of a similarly
 743 named environment variable:
 744
 745 - cache-root
 746 - include
 747 - project-list
 748 - scan-path
 749
 750 Macro expansion will also happen on the content of $CGIT_CONFIG, if
 751 defined.
 752
 753 One usage of this feature is virtual hosting, which in its simplest form
 754 can be accomplished by adding the following line to /etc/cgitrc:
 755
 756         include=/etc/cgitrc.d/$HTTP_HOST
 757
 758 The following options are expanded during request processing, and support
 759 the environment variables defined in "FILTER API":
 760
 761 - clone-url
 762 - repo.clone-url
 763
 764
 765 CACHE
 766 ------
 767
 768 All cache ttl values are in minutes. Negative ttl values indicate that a page
 769 type will never expire, and thus the first time a URL is accessed, the result
 770 will be cached indefinitely, even if the underlying git repository changes.
 771 Conversely, when a ttl value is zero, the cache is disabled for that
 772 particular page type, and the page type is never cached.
 773
