  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".

  64         version of repository pages accessed without a fixed SHA1. See also:
  65         "CACHE". Default value: "5".
  66
  67 cache-repo-ttl::
  68         Number which specifies the time-to-live, in minutes, for the cached
  69         version of the repository summary page. See also: "CACHE". Default
  70         value: "5".

 113
 114 commit-filter::
 115         Specifies a command which will be invoked to format commit messages.
 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
 124         ordering. If unset, the default ordering of "git log" is used. Default
 125         value: unset.
 126
 127 css::
 128         Url which specifies the css document to include in all cgit pages.
 129         Default value: "/cgit.css".
 130
 131 email-filter::
 132         Specifies a command which will be invoked to format names and email
 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,
 136         and the text to format on STDIN. It is to write the formatted text back
 137         out onto STDOUT. Default value: none. See also: "FILTER API".
 138
 139 embedded::
 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-blame::
 145         Flag which, when set to "1", will allow cgit to provide a "blame" page
 146         for files, and will make it generate links to that page in appropriate
 147         places. Default value: "0".
 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".

 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-git-config::
 163         Flag which, when set to "1", will allow cgit to use git config to set
 164         any repo specific settings. This option is used in conjunction with
 165         "scan-path", and must be defined prior, to augment repo-specific
 166         settings. The keys gitweb.owner, gitweb.category, gitweb.description,
 167         and gitweb.homepage will map to the cgit keys repo.owner, repo.section,
 168         repo.desc, and repo.homepage respectively. All git config keys that begin
 169         with "cgit." will be mapped to the corresponding "repo." key in cgit.
 170         Default value: "0". See also: scan-path, section-from-path.
 171
 172 enable-http-clone::
 173         If set to "1", cgit will act as a dumb HTTP endpoint for git clones.
 174         You can add "http://$HTTP_HOST$SCRIPT_NAME/$CGIT_REPO_URL" to clone-url
 175         to expose this feature. If you use an alternate way of serving git
 176         repositories, you may wish to disable this. Default value: "1".
 177
 178 enable-html-serving::
 179         Flag which, when set to "1", will allow the /plain handler to serve
 180         mimetype headers that result in the file being treated as HTML by the
 181         browser. When set to "0", such file types are returned instead as
 182         text/plain or application/octet-stream. Default value: "0". See also:
 183         "repo.enable-html-serving".
 184
 185 enable-index-links::
 186         Flag which, when set to "1", will make cgit generate extra links for
 187         each repo in the repository index (specifically, to the "summary",
 188         "commit" and "tree" pages). Default value: "0".
 189

 197         value: "0".
 198
 199 enable-log-linecount::
 200         Flag which, when set to "1", will make cgit print the number of added
 201         and removed lines for each commit on the repository log page. Default
 202         value: "0".
 203
 204 enable-remote-branches::
 205         Flag which, when set to "1", will make cgit display remote branches
 206         in the summary and refs views. Default value: "0". See also:
 207         "repo.enable-remote-branches".
 208
 209 enable-subject-links::
 210         Flag which, when set to "1", will make cgit use the subject of the
 211         parent commit as link text when generating links to parent commits
 212         in commit view. Default value: "0". See also:
 213         "repo.enable-subject-links".
 214
 215 enable-tree-linenumbers::
 216         Flag which, when set to "1", will make cgit generate linenumber links
 217         for plaintext blobs printed in the tree view. Default value: "1".
 218
 219 favicon::
 220         Url used as link to a shortcut icon for cgit. It is suggested to use
 221         the value "/favicon.ico" since certain browsers will ignore other
 222         values. Default value: "/favicon.ico".
 223
 224 footer::
 225         The content of the file specified with this option will be included
 226         verbatim at the bottom of all pages (i.e. it replaces the standard
 227         "generated by..." message. Default value: none.

 268         "log" view. Default value: "80".
 269
 270 max-repo-count::
 271         Specifies the number of entries to list per page on the repository
 272         index page. Default value: "50".
 273
 274 max-repodesc-length::
 275         Specifies the maximum number of repo description characters to display
 276         on the repository index page. Default value: "80".
 277
 278 max-stats::
 279         Set the default maximum statistics period. Valid values are "week",
 280         "month", "quarter" and "year". If unspecified, statistics are
 281         disabled. Default value: none. See also: "repo.max-stats".
 282
 283 mimetype.<ext>::
 284         Set the mimetype for the specified filename extension. This is used
 285         by the `plain` command when returning blob content.
 286
 287 mimetype-file::
 288         Specifies the file to use for automatic mimetype lookup. If specified
 289         then this field is used as a fallback when no "mimetype.<ext>" match is
 290         found. If unspecified then no such lookup is performed. The typical file
 291         to use on a Linux system is /etc/mime.types. The format of the file must
 292         comply to:
 293         - a comment line is an empty line or a line starting with a hash (#),
 294           optionally preceded by whitespace
 295         - a non-comment line starts with the mimetype (like image/png), followed
 296           by one or more file extensions (like jpg), all separated by whitespace
 297         Default value: none. See also: "mimetype.<ext>".
 298

 302         formatstring are the path and SHA1 of the submodule commit. Default
 303         value: none.
 304
 305 noplainemail::
 306         If set to "1" showing full author email addresses will be disabled.

 308
 309 noheader::
 310         Flag which, when set to "1", will make cgit omit the standard header
 311         on all pages. Default value: none. See also: "embedded".
 312
 313 owner-filter::
 314         Specifies a command which will be invoked to format the Owner
 315         column of the main page.  The command will get the owner on STDIN,
 316         and the STDOUT from the command will be included verbatim in the
 317         table.  This can be used to link to additional context such as an
 318         owners home page.  When active this filter is used instead of the
 319         default owner query url.  Default value: none.
 320         See also: "FILTER API".
 321
 322 project-list::
 323         A list of subdirectories inside of scan-path, relative to it, that
 324         should loaded as git repositories. This must be defined prior to

 326         EXPANSION".
 327
 328 readme::
 329         Text which will be used as default value for "repo.readme". Multiple
 330         config keys may be specified, and cgit will use the first found file
 331         in this list. This is useful in conjunction with scan-path. Default
 332         value: none. See also: scan-path, repo.readme.
 333
 334 remove-suffix::
 335         If set to "1" and scan-path is enabled, if any repositories are found
 336         with a suffix of ".git", this suffix will be removed for the url and
 337         name. This must be defined prior to scan-path. Default value: "0".
 338         See also: scan-path.
 339
 340 renamelimit::
 341         Maximum number of files to consider when detecting renames. The value
 342          "-1" uses the compiletime value in git (for further info, look at
 343           `man git-diff`). Default value: "-1".
 344
 345 repository-sort::
 346         The way in which repositories in each section are sorted. Valid values
 347         are "name" for sorting by the repo name or "age" for sorting by the

 357         value: "a fast webinterface for the git dscm".
 358
 359 root-readme::
 360         The content of the file specified with this option will be included
 361         verbatim below the "about" link on the repository index page. Default
 362         value: none.
 363
 364 root-title::
 365         Text printed as heading on the repository index page. Default value:
 366         "Git Repository Browser".
 367
 368 scan-hidden-path::
 369         If set to "1" and scan-path is enabled, scan-path will recurse into
 370         directories whose name starts with a period ('.'). Otherwise,
 371         scan-path will stay away from such directories (considered as
 372         "hidden"). Note that this does not apply to the ".git" directory in
 373         non-bare repos. This must be defined prior to scan-path.
 374         Default value: 0. See also: scan-path.
 375
 376 scan-path::
 377         A path which will be scanned for repositories. If caching is enabled,
 378         the result will be cached as a cgitrc include-file in the cache
 379         directory. If project-list has been defined prior to scan-path,
 380         scan-path loads only the directories listed in the file pointed to by
 381         project-list. Be advised that only the global settings taken
 382         before the scan-path directive will be applied to each repository.
 383         Default value: none. See also: cache-scanrc-ttl, project-list,
 384         "MACRO EXPANSION".
 385
 386 section::
 387         The name of the current repository section - all repositories defined
 388         after this option will inherit the current section name. Default value:
 389         none.
 390
 391 section-sort::
 392         Flag which, when set to "1", will sort the sections on the repository
 393         listing by name. Set this flag to "0" if the order in the cgitrc file should
 394         be preserved. Default value: "1". See also: section,
 395         case-sensitive-sort, repository-sort.
 396
 397 section-from-path::
 398         A number which, if defined prior to scan-path, specifies how many
 399         path elements from each repo path to use as a default section name.
 400         If negative, cgit will discard the specified number of path elements
 401         above the repo directory. Default value: "0".
 402
 403 side-by-side-diffs::
 404         If set to "1" shows side-by-side diffs instead of unidiffs per
 405         default. Default value: "0".
 406
 407 snapshots::
 408         Text which specifies the default set of snapshot formats that cgit
 409         generates links for. The value is a space-separated list of zero or
 410         more of the values "tar", "tar.gz", "tar.bz2", "tar.xz" and "zip".
 411         The special value "all" enables all snapshot formats.
 412         Default value: none.
 413
 414 source-filter::
 415         Specifies a command which will be invoked to format plaintext blobs
 416         in the tree view. The command will get the blob content on its STDIN
 417         and the name of the blob as its only command line argument. The STDOUT
 418         from the command will be included verbatim as the blob contents, i.e.
 419         this can be used to implement e.g. syntax highlighting. Default value:
 420         none. See also: "FILTER API".
 421
 422 summary-branches::
 423         Specifies the number of branches to display in the repository "summary"
 424         view. Default value: "10".
 425
 426 summary-log::
 427         Specifies the number of log entries to display in the repository
 428         "summary" view. Default value: "10".
 429
 430 summary-tags::
 431         Specifies the number of tags to display in the repository "summary"
 432         view. Default value: "10".
 433
 434 strict-export::
 435         Filename which, if specified, needs to be present within the repository
 436         for cgit to allow access to that repository. This can be used to emulate
 437         gitweb's EXPORT_OK and STRICT_EXPORT functionality and limit cgit's
 438         repositories to match those exported by git-daemon. This option must
 439         be defined prior to scan-path.
 440
 441 virtual-root::
 442         Url which, if specified, will be used as root for all cgit links. It
 443         will also cause cgit to generate 'virtual urls', i.e. urls like
 444         '/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
 445         value: none.
 446         NOTE: cgit has recently learned how to use PATH_INFO to achieve the
 447         same kind of virtual urls, so this option will probably be deprecated.
 448

 538         Url loaded when clicking on the cgit logo image. If unspecified the
 539         calculated url of the repository index page will be used. Default
 540         value: global logo-link.
 541
 542 repo.module-link::
 543         Text which will be used as the formatstring for a hyperlink when a
 544         submodule is printed in a directory listing. The arguments for the
 545         formatstring are the path and SHA1 of the submodule commit. Default
 546         value: <module-link>
 547
 548 repo.module-link.<path>::
 549         Text which will be used as the formatstring for a hyperlink when a
 550         submodule with the specified subdirectory path is printed in a
 551         directory listing. The only argument for the formatstring is the SHA1
 552         of the submodule commit. Default value: none.
 553
 554 repo.max-stats::
 555         Override the default maximum statistics period. Valid values are equal
 556         to the values specified for the global "max-stats" setting. Default
 557         value: none.
 558
 559 repo.name::
 560         The value to show as repository name. Default value: <repo.url>.
 561
 562 repo.owner::
 563         A value used to identify the owner of the repository. Default value:
 564         none.
 565
 566 repo.owner-filter::
 567         Override the default owner-filter. Default value: none. See also:
 568         "enable-filter-overrides". See also: "FILTER API".
 569
 570 repo.path::
 571         An absolute path to the repository directory. For non-bare repositories
 572         this is the .git-directory. Default value: none.
 573
 574 repo.readme::
 575         A path (relative to <repo.path>) which specifies a file to include
 576         verbatim as the "About" page for this repo. You may also specify a
 577         git refspec by head or by hash by prepending the refspec followed by
 578         a colon. For example, "master:docs/readme.mkd". If the value begins
 579         with a colon, i.e. ":docs/readme.rst", the default branch of the
 580         repository will be used. Sharing any file will expose that entire
 581         directory tree to the "/about/PATH" endpoints, so be sure that there
 582         are no non-public files located in the same directory as the readme
 583         file. Default value: <readme>.
 584
 585 repo.section::
 586         Override the current section name for this repository. Default value:
 587         none.
 588
 589 repo.snapshots::
 590         A mask of snapshot formats for this repo that cgit generates links for,
 591         restricted by the global "snapshots" setting. Default value:
 592         <snapshots>.
 593
 594 repo.snapshot-prefix::
 595         Prefix to use for snapshot links instead of the repository basename.
 596         For example, the "linux-stable" repository may wish to set this to
 597         "linux" so that snapshots are in the format "linux-3.15.4" instead
 598         of "linux-stable-3.15.4".  Default value: <empty> meaning to use
 599         the repository basename.
 600
 601 repo.source-filter::
 602         Override the default source-filter. Default value: none. See also:
 603         "enable-filter-overrides". See also: "FILTER API".
 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 auth filter::
 674         The authentication filter receives 12 parameters:
 675           - filter action, explained below, which specifies which action the
 676             filter is called for
 677           - http cookie
 678           - http method
 679           - http referer
 680           - http path
 681           - http https flag
 682           - cgit repo
 683           - cgit page
 684           - cgit url
 685           - cgit login url
 686         When the filter action is "body", this filter must write to output the
 687         HTML for displaying the login form, which POSTs to the login url. When
 688         the filter action is "authenticate-cookie", this filter must validate
 689         the http cookie and return a 0 if it is invalid or 1 if it is invalid,
 690         in the exit code / close function. If the filter action is
 691         "authenticate-post", this filter receives POST'd parameters on
 692         standard input, and should write a complete CGI response, preferably
 693         with a 302 redirect, and write to output one or more "Set-Cookie"
 694         HTTP headers, each followed by a newline.
 695
 696         Please see `filters/simple-authentication.lua` for a clear example
 697         script that may be modified.
 698
 699 commit filter::
 700         This filter is given no arguments. The commit message text that is to
 701         be filtered is available on standard input and the filtered text is
 702         expected on standard output.
 703
 704 email filter::
 705         This filter is given two parameters: the email address of the relevant
 706         author and a string indicating the originating page. The filter will
 707         then receive the text string to format on standard input and is
 708         expected to write to standard output the formatted text to be included
 709         in the page.
 710
 711 owner filter::
 712         This filter is given no arguments.  The owner text is available on
 713         standard input and the filter is expected to write to standard
 714         output.  The output is included in the Owner column.
 715
 716 source filter::
 717         This filter is given a single parameter: the filename of the source
 718         file to filter. The filter can use the filename to determine (for
 719         example) the syntax highlighting mode. The contents of the source
 720         file that is to be filtered is available on standard input and the
 721         filtered contents is expected on standard output.
 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
 774 SIGNATURES
 775 ----------
 776
 777 Cgit can host .asc signatures corresponding to various snapshot formats,
 778 through use of git notes. For example, the following command may be used to
 779 add a signature to a .tar.xz archive:
 780
 781     git notes --ref=refs/notes/signatures/tar.xz add -C "$(
 782         gpg --output - --armor --detach-sign cgit-1.1.tar.xz |
 783         git hash-object -w --stdin
 784     )" v1.1
 785
 786 If it is instead desirable to attach a signature of the underlying .tar, this
 787 will be linked, as a special case, beside a .tar.* link that does not have its
 788 own signature. For example, a signature of a tarball of the latest tag might
 789 be added with a similar command:
 790
 791     tag="$(git describe --abbrev=0)"
 792     git notes --ref=refs/notes/signatures/tar add -C "$(
 793         git archive --format tar --prefix "cgit-${tag#v}/" "$tag" |
 794         gpg --output - --armor --detach-sign |
 795         git hash-object -w --stdin
 796     )" "$tag"
 797
 798 Since git-archive(1) is expected to produce stable output between versions,
 799 this allows one to generate a long-term signature of the contents of a given
 800 tag.
