You can set variables +using "`our $variable = value`"; text from a "#" character until the +end of a line is ignored. See *perlsyn*(1) for details. + +An example: + + # gitweb configuration file for http://git.example.org + # + our $projectroot = "/srv/git"; # FHS recommendation + our $site_name = 'Example.org >> Repos'; + + +The configuration file is used to override the default settings that +were built into gitweb at the time the 'gitweb.cgi' script was generated. + +While one could just alter the configuration settings in the gitweb +CGI itself, those changes would be lost upon upgrade. Configuration +settings might also be placed into a file in the same directory as the +CGI script with the default name 'gitweb_config.perl' -- allowing +one to have multiple gitweb instances with different configurations by +the use of symlinks. + +Note that some configuration can be controlled on per-repository rather than +gitweb-wide basis: see "Per-repository gitweb configuration" subsection on +linkgit:gitweb[1] manpage. + + +DISCUSSION +---------- +Gitweb reads configuration data from the following sources in the +following order: + + * built-in values (some set during build stage), + + * common system-wide configuration file (defaults to + '/etc/gitweb-common.conf'), + + * either per-instance configuration file (defaults to 'gitweb_config.perl' + in the same directory as the installed gitweb), or if it does not exists + then fallback system-wide configuration file (defaults to '/etc/gitweb.conf'). + +Values obtained in later configuration files override values obtained earlier +in the above sequence. + +Locations of the common system-wide configuration file, the fallback +system-wide configuration file and the per-instance configuration file +are defined at compile time using build-time Makefile configuration +variables, respectively `GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM` +and `GITWEB_CONFIG`. + +You can also override locations of gitweb configuration files during +runtime by setting the following environment variables: +`GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM` and `GITWEB_CONFIG` +to a non-empty value. + + +The syntax of the configuration files is that of Perl, since these files are +handled by sourcing them as fragments of Perl code (the language that +gitweb itself is written in). Variables are typically set using the +`our` qualifier (as in "`our $variable = <value>;`") to avoid syntax +errors if a new version of gitweb no longer uses a variable and therefore +stops declaring it. + +You can include other configuration file using read_config_file() +subroutine. For example, one might want to put gitweb configuration +related to access control for viewing repositories via Gitolite (one +of git repository management tools) in a separate file, e.g. in +'/etc/gitweb-gitolite.conf'. To include it, put + +-------------------------------------------------- +read_config_file("/etc/gitweb-gitolite.conf"); +-------------------------------------------------- + +somewhere in gitweb configuration file used, e.g. in per-installation +gitweb configuration file. Note that read_config_file() checks itself +that the file it reads exists, and does nothing if it is not found. +It also handles errors in included file. + + +The default configuration with no configuration file at all may work +perfectly well for some installations. Still, a configuration file is +useful for customizing or tweaking the behavior of gitweb in many ways, and +some optional features will not be present unless explicitly enabled using +the configurable `%features` variable (see also "Configuring gitweb +features" section below). + + +CONFIGURATION VARIABLES +----------------------- +Some configuration variables have their default values (embedded in the CGI +script) set during building gitweb -- if that is the case, this fact is put +in their description. See gitweb's 'INSTALL' file for instructions on building +and installing gitweb. + + +Location of repositories +~~~~~~~~~~~~~~~~~~~~~~~~ +The configuration variables described below control how gitweb finds +git repositories, and how repositories are displayed and accessed. + +See also "Repositories" and later subsections in linkgit:gitweb[1] manpage. + +$projectroot:: + Absolute filesystem path which will be prepended to project path; + the path to repository is `$projectroot/$project`. Set to + `$GITWEB_PROJECTROOT` during installation. This variable has to be + set correctly for gitweb to find repositories. ++ +For example, if `$projectroot` is set to "/srv/git" by putting the following +in gitweb config file: ++ +---------------------------------------------------------------------------- +our $projectroot = "/srv/git"; +---------------------------------------------------------------------------- ++ +then ++ +------------------------------------------------ +http://git.example.com/gitweb.cgi?p=foo/bar.git +------------------------------------------------ ++ +and its path_info based equivalent ++ +------------------------------------------------ +http://git.example.com/gitweb.cgi/foo/bar.git +------------------------------------------------ ++ +will map to the path '/srv/git/foo/bar.git' on the filesystem. + +$projects_list:: + Name of a plain text file listing projects, or a name of directory + to be scanned for projects. ++ +Project list files should list one project per line, with each line +having the following format ++ +----------------------------------------------------------------------------- +<URI-encoded filesystem path to repository> SP <URI-encoded repository owner> +----------------------------------------------------------------------------- ++ +The default value of this variable is determined by the `GITWEB_LIST` +makefile variable at installation time. If this variable is empty, gitweb +will fall back to scanning the `$projectroot` directory for repositories. + +$project_maxdepth:: + If `$projects_list` variable is unset, gitweb will recursively + scan filesystem for git repositories. The `$project_maxdepth` + is used to limit traversing depth, relative to `$projectroot` + (starting point); it means that directories which are further + from `$projectroot` than `$project_maxdepth` will be skipped. ++ +It is purely performance optimization, originally intended for MacOS X, +where recursive directory traversal is slow. Gitweb follows symbolic +links, but it detects cycles, ignoring any duplicate files and directories. ++ +The default value of this variable is determined by the build-time +configuration variable `GITWEB_PROJECT_MAXDEPTH`, which defaults to +2007. + +$export_ok:: + Show repository only if this file exists (in repository). Only + effective if this variable evaluates to true. Can be set when + building gitweb by setting `GITWEB_EXPORT_OK`. This path is + relative to `GIT_DIR`. git-daemon[1] uses 'git-daemon-export-ok', + unless started with `--export-all`. By default this variable is + not set, which means that this feature is turned off. + +$export_auth_hook:: + Function used to determine which repositories should be shown. + This subroutine should take one parameter, the full path to + a project, and if it returns true, that project will be included + in the projects list and can be accessed through gitweb as long + as it fulfills the other requirements described by $export_ok, + $projects_list, and $projects_maxdepth. Example: ++ +---------------------------------------------------------------------------- +our $export_auth_hook = sub { return -e "$_[0]/git-daemon-export-ok"; }; +---------------------------------------------------------------------------- ++ +though the above might be done by using `$export_ok` instead ++ +---------------------------------------------------------------------------- +our $export_ok = "git-daemon-export-ok"; +---------------------------------------------------------------------------- ++ +If not set (default), it means that this feature is disabled. ++ +See also more involved example in "Controlling access to git repositories" +subsection on linkgit:gitweb[1] manpage. + +$strict_export:: + Only allow viewing of repositories also shown on the overview page. + This for example makes `$gitweb_export_ok` file decide if repository is + available and not only if it is shown. If `$gitweb_list` points to + file with list of project, only those repositories listed would be + available for gitweb. Can be set during building gitweb via + `GITWEB_STRICT_EXPORT`. By default this variable is not set, which + means that you can directly access those repositories that are hidden + from projects list page (e.g. the are not listed in the $projects_list + file). + + +Finding files +~~~~~~~~~~~~~ +The following configuration variables tell gitweb where to find files. +The values of these variables are paths on the filesystem. + +$GIT:: + Core git executable to use. By default set to `$GIT_BINDIR/git`, which + in turn is by default set to `$(bindir)/git`. If you use git installed + from a binary package, you should usually set this to "/usr/bin/git". + This can just be "git" if your web server has a sensible PATH; from + security point of view it is better to use absolute path to git binary. + If you have multiple git versions installed it can be used to choose + which one to use. Must be (correctly) set for gitweb to be able to + work. + +$mimetypes_file:: + File to use for (filename extension based) guessing of MIME types before + trying '/etc/mime.types'. *NOTE* that this path, if relative, is taken + as relative to the current git repository, not to CGI script. If unset, + only '/etc/mime.types' is used (if present on filesystem). If no mimetypes + file is found, mimetype guessing based on extension of file is disabled. + Unset by default. + +$highlight_bin:: + Path to the highlight executable to use (it must be the one from + http://www.andre-simon.de[] due to assumptions about parameters and output). + By default set to 'highlight'; set it to full path to highlight + executable if it is not installed on your web server's PATH. + Note that 'highlight' feature must be set for gitweb to actually + use syntax hightlighting. ++ +*NOTE*: if you want to add support for new file type (supported by +"highlight" but not used by gitweb), you need to modify `%highlight_ext` +or `%highlight_basename`, depending on whether you detect type of file +based on extension (for example "sh") or on its basename (for example +"Makefile"). The keys of these hashes are extension and basename, +respectively, and value for given key is name of syntax to be passed via +`--syntax <syntax>` to highlighter. ++ +For example if repositories you are hosting use "phtml" extension for +PHP files, and you want to have correct syntax-highlighting for those +files, you can add the following to gitweb configuration: ++ +--------------------------------------------------------- +our %highlight_ext; +$highlight_ext{'phtml'} = 'php'; +--------------------------------------------------------- + + +Links and their targets +~~~~~~~~~~~~~~~~~~~~~~~ +The configuration variables described below configure some of gitweb links: +their target and their look (text or image), and where to find page +prerequisites (stylesheet, favicon, images, scripts). Usually they are left +at their default values, with the possible exception of `@stylesheets` +variable. + +@stylesheets:: + List of URIs of stylesheets (relative to the base URI of a page). You + might specify more than one stylesheet, for example to use "gitweb.css" + as base with site specific modifications in a separate stylesheet + to make it easier to upgrade gitweb. For example, you can add + a `site` stylesheet by putting ++ +---------------------------------------------------------------------------- +push @stylesheets, "gitweb-site.css"; +---------------------------------------------------------------------------- ++ +in the gitweb config file. Those values that are relative paths are +relative to base URI of gitweb. ++ +This list should contain the URI of gitweb's standard stylesheet. The default +URI of gitweb stylesheet can be set at build time using the `GITWEB_CSS` +makefile variable. Its default value is 'static/gitweb.css' +(or 'static/gitweb.min.css' if the `CSSMIN` variable is defined, +i.e. if CSS minifier is used during build). ++ +*Note*: there is also a legacy `$stylesheet` configuration variable, which was +used by older gitweb. If `$stylesheet` variable is defined, only CSS stylesheet +given by this variable is used by gitweb. + +$logo:: + Points to the location where you put 'git-logo.png' on your web + server, or to be more the generic URI of logo, 72x27 size). This image + is displayed in the top right corner of each gitweb page and used as + a logo for the Atom feed. Relative to the base URI of gitweb (as a path). + Can be adjusted when building gitweb using `GITWEB_LOGO` variable + By default set to 'static/git-logo.png'. + +$favicon:: + Points to the location where you put 'git-favicon.png' on your web + server, or to be more the generic URI of favicon, which will be served + as "image/png" type. Web browsers that support favicons (website icons) + may display them in the browser's URL bar and next to the site name in + bookmarks. Relative to the base URI of gitweb. Can be adjusted at + build time using `GITWEB_FAVICON` variable. + By default set to 'static/git-favicon.png'. + +$javascript:: + Points to the location where you put 'gitweb.js' on your web server, + or to be more generic the URI of JavaScript code used by gitweb. + Relative to the base URI of gitweb. Can be set at build time using + the `GITWEB_JS` build-time configuration variable. ++ +The default value is either 'static/gitweb.js', or 'static/gitweb.min.js' if +the `JSMIN` build variable was defined, i.e. if JavaScript minifier was used +at build time. *Note* that this single file is generated from multiple +individual JavaScript "modules". + +$home_link:: + Target of the home link on the top of all pages (the first part of view + "breadcrumbs"). By default it is set to the absolute URI of a current page + (to the value of `$my_uri` variable, or to "/" if `$my_uri` is undefined + or is an empty string). + +$home_link_str:: + Label for the "home link" at the top of all pages, leading to `$home_link` + (usually the main gitweb page, which contains the projects list). It is + used as the first component of gitweb's "breadcrumb trail": + `<home link> / <project> / <action>`. Can be set at build time using + the `GITWEB_HOME_LINK_STR` variable. By default it is set to "projects", + as this link leads to the list of projects. Other popular choice it to + set it to the name of site. + +$logo_url:: +$logo_label:: + URI and label (title) for the Git logo link (or your site logo, + if you chose to use different logo image). By default, these both + refer to git homepage, http://git-scm.com[]; in the past, they pointed + to git documentation at http://www.kernel.org[]. + + +Changing gitweb's look +~~~~~~~~~~~~~~~~~~~~~~ +You can adjust how pages generated by gitweb look using the variables described +below. You can change the site name, add common headers and footers for all +pages, and add a description of this gitweb installation on its main page +(which is the projects list page), etc. + +$site_name:: + Name of your site or organization, to appear in page titles. Set it + to something descriptive for clearer bookmarks etc. If this variable + is not set or is, then gitweb uses the value of the `SERVER_NAME` + CGI environment variable, setting site name to "$SERVER_NAME Git", + or "Untitled Git" if this variable is not set (e.g. if running gitweb + as standalone script). ++ +Can be set using the `GITWEB_SITENAME` at build time. Unset by default. + +$site_html_head_string:: + HTML snippet to be included in the <head> section of each page. + Can be set using `GITWEB_SITE_HTML_HEAD_STRING` at build time. + No default value. + +$site_header:: + Name of a file with HTML to be included at the top of each page. + Relative to the directory containing the 'gitweb.cgi' script. + Can be set using `GITWEB_SITE_HEADER` at build time. No default + value. + +$site_footer:: + Name of a file with HTML to be included at the bottom of each page. + Relative to the directory containing the 'gitweb.cgi' script. + Can be set using `GITWEB_SITE_FOOTER` at build time. No default + value. + +$home_text:: + Name of a HTML file which, if it exists, is included on the + gitweb projects overview page ("projects_list" view). Relative to + the directory containing the gitweb.cgi script. Default value + can be adjusted during build time using `GITWEB_HOMETEXT` variable. + By default set to 'indextext.html'. + +$projects_list_description_width:: + The width (in characters) of the "Description" column of the projects list. + Longer descriptions will be truncated (trying to cut at word boundary); + the full description is available in the 'title' attribute (usually shown on + mouseover). The default is 25, which might be too small if you + use long project descriptions. + +$default_projects_order:: + Default value of ordering of projects on projects list page, which + means the ordering used if you don't explicitly sort projects list + (if there is no "o" CGI query parameter in the URL). Valid values + are "none" (unsorted), "project" (projects are by project name, + i.e. path to repository relative to `$projectroot`), "descr" + (project description), "owner", and "age" (by date of most current + commit). ++ +Default value is "project". Unknown value means unsorted. + + +Changing gitweb's behavior +~~~~~~~~~~~~~~~~~~~~~~~~~~ +These configuration variables control _internal_ gitweb behavior. + +$default_blob_plain_mimetype:: + Default mimetype for the blob_plain (raw) view, if mimetype checking + doesn't result in some other type; by default "text/plain". + Gitweb guesses mimetype of a file to display based on extension + of its filename, using `$mimetypes_file` (if set and file exists) + and '/etc/mime.types' files (see *mime.types*(5) manpage; only + filename extension rules are supported by gitweb). + +$default_text_plain_charset:: + Default charset for text files. If this is not set, the web server + configuration will be used. Unset by default. + +$fallback_encoding:: + Gitweb assumes this charset when a line contains non-UTF-8 characters. + The fallback decoding is used without error checking, so it can be even + "utf-8". The value must be a valid encoding; see the *Encoding::Supported*(3pm) + man page for a list. The default is "latin1", aka. "iso-8859-1". + +@diff_opts:: + Rename detection options for git-diff and git-diff-tree. The default is + (\'-M'); set it to (\'-C') or (\'-C', \'-C') to also detect copies, + or set it to () i.e. empty list if you don't want to have renames + detection. ++ +*Note* that rename and especially copy detection can be quite +CPU-intensive. Note also that non git tools can have problems with +patches generated with options mentioned above, especially when they +involve file copies (\'-C') or criss-cross renames (\'-B'). + + +Some optional features and policies +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Most of features are configured via `%feature` hash; however some of extra +gitweb features can be turned on and configured using variables described +below. This list beside configuration variables that control how gitweb +looks does contain variables configuring administrative side of gitweb +(e.g. cross-site scripting prevention; admittedly this as side effect +affects how "summary" pages look like, or load limiting). + +@git_base_url_list:: + List of git base URLs. These URLs are used to generate URLs + describing from where to fetch a project, which are shown on + project summary page. The full fetch URL is "`$git_base_url/$project`", + for each element of this list. You can set up multiple base URLs + (for example one for `git://` protocol, and one for `http://` + protocol). ++ +Note that per repository configuration can be set in '$GIT_DIR/cloneurl' +file, or as values of multi-value `gitweb.url` configuration variable in +project config. Per-repository configuration takes precedence over value +composed from `@git_base_url_list` elements and project name. ++ +You can setup one single value (single entry/item in this list) at build +time by setting the `GITWEB_BASE_URL` built-time configuration variable. +By default it is set to (), i.e. an empty list. This means that gitweb +would not try to create project URL (to fetch) from project name. + +$projects_list_group_categories:: + Whether to enables the grouping of projects by category on the project + list page. The category of a project is determined by the + `$GIT_DIR/category` file or the `gitweb.category` variable in each + repository's configuration. Disabled by default (set to 0). + +$project_list_default_category:: + Default category for projects for which none is specified. If this is + set to the empty string, such projects will remain uncategorized and + listed at the top, above categorized projects. Used only if project + categories are enabled, which means if `$projects_list_group_categories` + is true. By default set to "" (empty string). + +$prevent_xss:: + If true, some gitweb features are disabled to prevent content in + repositories from launching cross-site scripting (XSS) attacks. Set this + to true if you don't trust the content of your repositories. + False by default (set to 0). + +$maxload:: + Used to set the maximum load that we will still respond to gitweb queries. + If the server load exceeds this value then gitweb will return + "503 Service Unavailable" error. The server load is taken to be 0 + if gitweb cannot determine its value. Currently it works only on Linux, + where it uses '/proc/loadavg'; the load there is the number of active + tasks on the system -- processes that are actually running -- averaged + over the last minute. ++ +Set `$maxload` to undefined value (`undef`) to turn this feature off. +The default value is 300. + +$per_request_config:: + If this is set to code reference, it will be run once for each request. + You can set parts of configuration that change per session this way. + For example, one might use the following code in a gitweb configuration + file ++ +-------------------------------------------------------------------------------- +our $per_request_config = sub { + $ENV{GL_USER} = $cgi->remote_user || "gitweb"; +}; +-------------------------------------------------------------------------------- ++ +If `$per_request_config` is not a code reference, it is interpreted as boolean +value. If it is true gitweb will process config files once per request, +and if it is false gitweb will process config files only once, each time it +is executed. True by default (set to 1). ++ +*NOTE*: `$my_url`, `$my_uri`, and `$base_url` are overwritten with their default +values before every request, so if you want to change them, be sure to set +this variable to true or a code reference effecting the desired changes. ++ +This variable matters only when using persistent web environments that +serve multiple requests using single gitweb instance, like mod_perl, +FastCGI or Plackup. + + +Other variables +~~~~~~~~~~~~~~~ +Usually you should not need to change (adjust) any of configuration +variables described below; they should be automatically set by gitweb to +correct value. + + +$version:: + Gitweb version, set automatically when creating gitweb.cgi from + gitweb.perl. You might want to modify it if you are running modified + gitweb, for example ++ +--------------------------------------------------- +our $version .= " with caching"; +--------------------------------------------------- ++ +if you run modified version of gitweb with caching support. This variable +is purely informational, used e.g. in the "generator" meta header in HTML +header. + +$my_url:: +$my_uri:: + Full URL and absolute URL of the gitweb script; + in earlier versions of gitweb you might have need to set those + variables, but now there should be no need to do it. See + `$per_request_config` if you need to set them still. + +$base_url:: + Base URL for relative URLs in pages generated by gitweb, + (e.g. `$logo`, `$favicon`, `@stylesheets` if they are relative URLs), + needed and used '<base href="$base_url">' only for URLs with nonempty + PATH_INFO. Usually gitweb sets its value correctly, + and there is no need to set this variable, e.g. to $my_uri or "/". + See `$per_request_config` if you need to override it anyway. + + +CONFIGURING GITWEB FEATURES +--------------------------- +Many gitweb features can be enabled (or disabled) and configured using the +`%feature` hash. Names of gitweb features are keys of this hash. + +Each `%feature` hash element is a hash reference and has the following +structure: +---------------------------------------------------------------------- +"<feature_name>" => { + "sub" => <feature-sub (subroutine)>, + "override" => <allow-override (boolean)>, + "default" => [ <options>... ] +}, +---------------------------------------------------------------------- +Some features cannot be overridden per project. For those +features the structure of appropriate `%feature` hash element has a simpler +form: +---------------------------------------------------------------------- +"<feature_name>" => { + "override" => 0, + "default" => [ <options>... ] +}, +---------------------------------------------------------------------- +As one can see it lacks the \'sub' element. + +The meaning of each part of feature configuration is described +below: + +default:: + List (array reference) of feature parameters (if there are any), + used also to toggle (enable or disable) given feature. ++ +Note that it is currently *always* an array reference, even if +feature doesn't accept any configuration parameters, and \'default' +is used only to turn it on or off. In such case you turn feature on +by setting this element to `[1]`, and torn it off by setting it to +`[0]`. See also the passage about the "blame" feature in the "Examples" +section. ++ +To disable features that accept parameters (are configurable), you +need to set this element to empty list i.e. `[]`. + +override:: + If this field has a true value then the given feature is + overriddable, which means that it can be configured + (or enabled/disabled) on a per-repository basis. ++ +Usually given "<feature>" is configurable via the `gitweb.<feature>` +config variable in the per-repository git configuration file. ++ +*Note* that no feature is overriddable by default. + +sub:: + Internal detail of implementation. What is important is that + if this field is not present then per-repository override for + given feature is not supported. ++ +You wouldn't need to ever change it in gitweb config file. + + +Features in `%feature` +~~~~~~~~~~~~~~~~~~~~~~ +The gitweb features that are configurable via `%feature` hash are listed +below. This should be a complete list, but ultimately the authoritative +and complete list is in gitweb.cgi source code, with features described +in the comments. + +blame:: + Enable the "blame" and "blame_incremental" blob views, showing for + each line the last commit that modified it; see linkgit:git-blame[1]. + This can be very CPU-intensive and is therefore disabled by default. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.blame` configuration variable (boolean). + +snapshot:: + Enable and configure the "snapshot" action, which allows user to + download a compressed archive of any tree or commit, as produced + by linkgit:git-archive[1] and possibly additionally compressed. + This can potentially generate high traffic if you have large project. ++ +The value of \'default' is a list of names of snapshot formats, +defined in `%known_snapshot_formats` hash, that you wish to offer. +Supported formats include "tgz", "tbz2", "txz" (gzip/bzip2/xz +compressed tar archive) and "zip"; please consult gitweb sources for +a definitive list. By default only "tgz" is offered. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.blame` configuration variable, which contains +a comma separated list of formats or "none" to disable snapshots. +Unknown values are ignored. + +grep:: + Enable grep search, which lists the files in currently selected + tree (directory) containing the given string; see linkgit:git-grep[1]. + This can be potentially CPU-intensive, of course. Enabled by default. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.grep` configuration variable (boolean). + +pickaxe:: + Enable the so called pickaxe search, which will list the commits + that introduced or removed a given string in a file. This can be + practical and quite faster alternative to "blame" action, but it is + still potentially CPU-intensive. Enabled by default. ++ +The pickaxe search is described in linkgit:git-log[1] (the +description of `-S<string>` option, which refers to pickaxe entry in +linkgit:gitdiffcore[7] for more details). ++ +This feature can be configured on a per-repository basis by setting +repository's `gitweb.pickaxe` configuration variable (boolean). + +show-sizes:: + Enable showing size of blobs (ordinary files) in a "tree" view, in a + separate column, similar to what `ls -l` does; see description of + `-l` option in linkgit:git-ls-tree[1] manpage. This costs a bit of + I/O. Enabled by default. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.showsizes` configuration variable (boolean). + +patches:: + Enable and configure "patches" view, which displays list of commits in email + (plain text) output format; see also linkgit:git-format-patch[1]. + The value is the maximum number of patches in a patchset generated + in "patches" view. Set the 'default' field to a list containing single + item of or to an empty list to disable patch view, or to a list + containing a single negative number to remove any limit. + Default value is 16. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.patches` configuration variable (integer). + +avatar:: + Avatar support. When this feature is enabled, views such as + "shortlog" or "commit" will display an avatar associated with + the email of each committer and author. ++ +Currently available providers are *"gravatar"* and *"picon"*. +Only one provider at a time can be selected ('default' is one element list). +If an unknown provider is specified, the feature is disabled. +*Note* that some providers might require extra Perl packages to be +installed; see 'gitweb/INSTALL' for more details. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.avatar` configuration variable. ++ +See also `%avatar_size` with pixel sizes for icons and avatars +("default" is used for one-line like "log" and "shortlog", "double" +is used for two-line like "commit", "commitdiff" or "tag"). If the +default font sizes or lineheights are changed (e.g. via adding extra +CSS stylesheet in `@stylesheets`), it may be appropriate to change +these values. + +highlight:: + Server-side syntax highlight support in "blob" view. It requires + `$highlight_bin` program to be available (see the description of + this variable in the "Configuration variables" section above), + and therefore is disabled by default. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.highlight` configuration variable (boolean). + +remote_heads:: + Enable displaying remote heads (remote-tracking branches) in the "heads" + list. In most cases the list of remote-tracking branches is an + unnecessary internal private detail, and this feature is therefore + disabled by default. linkgit:git-instaweb[1], which is usually used + to browse local repositories, enables and uses this feature. ++ +This feature can be configured on a per-repository basis via +repository's `gitweb.remote_heads` configuration variable (boolean). + + +The remaining features cannot be overridden on a per project basis. + +search:: + Enable text search, which will list the commits which match author, + committer or commit text to a given string; see the description of + `--author`, `--committer` and `--grep` options in linkgit:git-log[1] + manpage. Enabled by default. ++ +Project specific override is not supported. + +forks:: + If this feature is enabled, gitweb considers projects in + subdirectories of project root (basename) to be forks of existing + projects. For each project `$projname.git`, projects in the + `$projname/` directory and its subdirectories will not be + shown in the main projects list. Instead, a \'+' mark is shown + next to `$projname`, which links to a "forks" view that lists all + the forks (all projects in `$projname/` subdirectory). Additionally + a "forks" view for a project is linked from project summary page. ++ +If the project list is taken from a file (`$projects_list` points to a +file), forks are only recognized if they are listed after the main project +in that file. ++ +Project specific override is not supported. + +actions:: + Insert custom links to the action bar of all project pages. This + allows you to link to third-party scripts integrating into gitweb. ++ +The "default" value consists of a list of triplets in the form +`("<label>", "<link>", "<position>")` where "position" is the label +after which to insert the link, "link" is a format string where `%n` +expands to the project name, `%f` to the project path within the +filesystem (i.e. "$projectroot/$project"), `%h` to the current hash +(\'h' gitweb parameter) and `%b` to the current hash base +(\'hb' gitweb parameter); `%%` expands to \'%'. ++ +For example, at the time this page was written, the http://repo.or.cz[] +git hosting site set it to the following to enable graphical log +(using the third party tool *git-browser*): ++ +---------------------------------------------------------------------- +$feature{'actions'}{'default'} = + [ ('graphiclog', '/git-browser/by-commit.html?r=%n', 'summary')]; +---------------------------------------------------------------------- ++ +This adds a link titled "graphiclog" after the "summary" link, leading to +`git-browser` script, passing `r=<project>` as a query parameter. ++ +Project specific override is not supported. + +timed:: + Enable displaying how much time and how many git commands it took to + generate and display each page in the page footer (at the bottom of + page). For example the footer might contain: "This page took 6.53325 + seconds and 13 git commands to generate." Disabled by default. ++ +Project specific override is not supported. + +javascript-timezone:: + Enable and configure the ability to change a common timezone for dates + in gitweb output via JavaScript. Dates in gitweb output include + authordate and committerdate in "commit", "commitdiff" and "log" + views, and taggerdate in "tag" view. Enabled by default. ++ +The value is a list of three values: a default timezone (for if the client +hasn't selected some other timezone and saved it in a cookie), a name of cookie +where to store selected timezone, and a CSS class used to mark up +dates for manipulation. If you want to turn this feature off, set "default" +to empty list: `[]`. ++ +Typical gitweb config files will only change starting (default) timezone, +and leave other elements at their default values: ++ +--------------------------------------------------------------------------- +$feature{'javascript-timezone'}{'default'}[0] = "utc"; +--------------------------------------------------------------------------- ++ +The example configuration presented here is guaranteed to be backwards +and forward compatible. ++ +Timezone values can be "local" (for local timezone that browser uses), "utc" +(what gitweb uses when JavaScript or this feature is disabled), or numerical +timezones in the form of "+/-HHMM", such as "+0200". ++ +Project specific override is not supported. + + +EXAMPLES +-------- + +To enable blame, pickaxe search, and snapshot support (allowing "tar.gz" and +"zip" snapshots), while allowing individual projects to turn them off, put +the following in your GITWEB_CONFIG file: + + $feature{'blame'}{'default'} = [1]; + $feature{'blame'}{'override'} = 1; + + $feature{'pickaxe'}{'default'} = [1]; + $feature{'pickaxe'}{'override'} = 1; + + $feature{'snapshot'}{'default'} = ['zip', 'tgz']; + $feature{'snapshot'}{'override'} = 1; + +If you allow overriding for the snapshot feature, you can specify which +snapshot formats are globally disabled. You can also add any command line +options you want (such as setting the compression level). For instance, you +can disable Zip compressed snapshots and set *gzip*(1) to run at level 6 by +adding the following lines to your gitweb configuration file: + + $known_snapshot_formats{'zip'}{'disabled'} = 1; + $known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6']; + +ENVIRONMENT +----------- +The location of per-instance and system-wide configuration files can be +overridden using the following environment variables: + +GITWEB_CONFIG:: + Sets location of per-instance configuration file. +GITWEB_CONFIG_SYSTEM:: + Sets location of fallback system-wide configuration file. + This file is read only if per-instance one does not exist. +GITWEB_CONFIG_COMMON:: + Sets location of common system-wide configuration file. + + +FILES +----- +gitweb_config.perl:: + This is default name of per-instance configuration file.

It's features include: + +* Viewing multiple Git repositories with common root. +* Browsing every revision of the repository. +* Viewing the contents of files in the repository at any revision. +* Viewing the revision log of branches, history of files and directories, + see what was changed when, by who. +* Viewing the blame/annotation details of any file (if enabled). +* Generating RSS and Atom feeds of commits, for any branch. + The feeds are auto-discoverable in modern web browsers. +* Viewing everything that was changed in a revision, and step through + revisions one at a time, viewing the history of the repository. +* Finding commits which commit messages matches given search term. + +See http://git.kernel.org/?p=git/git.git;a=tree;f=gitweb[] or +http://repo.or.cz/w/git.git/tree/HEAD:/gitweb/[] for gitweb source code, +browsed using gitweb itself. + + +CONFIGURATION +------------- +Various aspects of gitweb's behavior can be controlled through the configuration +file 'gitweb_config.perl' or '/etc/gitweb.conf'. See the linkgit:gitweb.conf[5] +for details. + +Repositories +~~~~~~~~~~~~ +Gitweb can show information from one or more Git repositories. These +repositories have to be all on local filesystem, and have to share common +repository root, i.e. be all under a single parent repository (but see also +"Advanced web server setup" section, "Webserver configuration with multiple +projects' root" subsection). + +----------------------------------------------------------------------- +our $projectroot = '/path/to/parent/directory'; +----------------------------------------------------------------------- + +The default value for `$projectroot` is '/pub/git'. You can change it during +building gitweb via `GITWEB_PROJECTROOT` build configuration variable. + +By default all git repositories under `$projectroot` are visible and available +to gitweb. The list of projects is generated by default by scanning the +`$projectroot` directory for git repositories (for object databases to be +more exact; gitweb is not interested in a working area, and is best suited +to showing "bare" repositories). + +The name of repository in gitweb is path to it's `$GIT_DIR` (it's object +database) relative to `$projectroot`. Therefore the repository $repo can be +found at "$projectroot/$repo". + + +Projects list file format +~~~~~~~~~~~~~~~~~~~~~~~~~ +Instead of having gitweb find repositories by scanning filesystem +starting from $projectroot, you can provide a pre-generated list of +visible projects by setting `$projects_list` to point to a plain text +file with a list of projects (with some additional info). + +This file uses the following format: + +* One record (for project / repository) per line; does not support line +continuation (newline escaping). + +* Leading and trailing whitespace are ignored. + +* Whitespace separated fields; any run of whitespace can be used as field +separator (rules for Perl's "`split(" ", $line)`"). + +* Fields use modified URI encoding, defined in RFC 3986, section 2.1 +(Percent-Encoding), or rather "Query string encoding" (see +link:http://en.wikipedia.org/wiki/Query_string#URL_encoding[]), the difference +being that SP (" ") can be encoded as "{plus}" (and therefore "{plus}" has to be +also percent-encoded). ++ +Reserved characters are: "%" (used for encoding), "{plus}" (can be used to +encode SPACE), all whitespace characters as defined in Perl, including SP, +TAB and LF, (used to separate fields in a record). + +* Currently recognized fields are: +<repository path>:: + path to repository GIT_DIR, relative to `$projectroot` +<repository owner>:: + displayed as repository owner, preferably full name, or email, + or both + +You can generate the projects list index file using the project_index action +(the 'TXT' link on projects list page) directly from gitweb; see also +"Generating projects list using gitweb" section below. + +Example contents: +----------------------------------------------------------------------- +foo.git Joe+R+Hacker+<joe@example.com> +foo/bar.git O+W+Ner+<owner@example.org> +----------------------------------------------------------------------- + + +By default this file controls only which projects are *visible* on projects +list page (note that entries that do not point to correctly recognized git +repositories won't be displayed by gitweb). Even if a project is not +visible on projects list page, you can view it nevertheless by hand-crafting +a gitweb URL. By setting `$strict_export` configuration variable (see +linkgit:gitweb.conf[5]) to true value you can allow viewing only of +repositories also shown on the overview page (i.e. only projects explicitly +listed in projects list file will be accessible). + + +Generating projects list using gitweb +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +We assume that GITWEB_CONFIG has its default Makefile value, namely +'gitweb_config.perl'. Put the following in 'gitweb_make_index.perl' file: +---------------------------------------------------------------------------- +read_config_file("gitweb_config.perl"); +$projects_list = $projectroot; +---------------------------------------------------------------------------- + +Then create the following script to get list of project in the format +suitable for GITWEB_LIST build configuration variable (or +`$projects_list` variable in gitweb config): + +---------------------------------------------------------------------------- +#!/bin/sh + +export GITWEB_CONFIG="gitweb_make_index.perl" +export GATEWAY_INTERFACE="CGI/1.1" +export HTTP_ACCEPT="*/*" +export REQUEST_METHOD="GET" +export QUERY_STRING="a=project_index" + +perl -- /var/www/cgi-bin/gitweb.cgi +---------------------------------------------------------------------------- + +Run this script and save its output to a file. This file could then be used +as projects list file, which means that you can set `$projects_list` to its +filename. + + +Controlling access to git repositories +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +By default all git repositories under `$projectroot` are visible and +available to gitweb. You can however configure how gitweb controls access +to repositories. + +* As described in "Projects list file format" section, you can control which +projects are *visible* by selectively including repositories in projects +list file, and setting `$projects_list` gitweb configuration variable to +point to it. With `$strict_export` set, projects list file can be used to +control which repositories are *available* as well. + +* You can configure gitweb to only list and allow viewing of the explicitly +exported repositories, via `$export_ok` variable in gitweb config file; see +linkgit:gitweb.conf[5] manpage. If it evaluates to true, gitweb shows +repositories only if this file named by `$export_ok` exists in its object +database (if directory has the magic file named `$export_ok`). ++ +For example linkgit:git-daemon[1] by default (unless `--export-all` option +is used) allows pulling only for those repositories that have +'git-daemon-export-ok' file. Adding ++ +-------------------------------------------------------------------------- +our $export_ok = "git-daemon-export-ok"; +-------------------------------------------------------------------------- ++ +makes gitweb show and allow access only to those repositories that can be +fetched from via `git://` protocol. + +* Finally, it is possible to specify an arbitrary perl subroutine that will +be called for each repository to determine if it can be exported. The +subroutine receives an absolute path to the project (repository) as its only +parameter (i.e. "$projectroot/$project"). ++ +For example, if you use mod_perl to run the script, and have dumb +HTTP protocol authentication configured for your repositories, you +can use the following hook to allow access only if the user is +authorized to read the files: ++ +-------------------------------------------------------------------------- +$export_auth_hook = sub { + use Apache2::SubRequest (); + use Apache2::Const -compile => qw(HTTP_OK); + my $path = "$_[0]/HEAD"; + my $r = Apache2::RequestUtil->request; + my $sub = $r->lookup_file($path); + return $sub->filename eq $path + && $sub->status == Apache2::Const::HTTP_OK; +}; +-------------------------------------------------------------------------- + + +Per-repository gitweb configuration +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +You can configure individual repositories shown in gitweb by creating file +in the 'GIT_DIR' of git repository, or by setting some repo configuration +variable (in 'GIT_DIR/config', see linkgit:git-config[1]). + +You can use the following files in repository: + +README.html:: + A html file (HTML fragment) which is included on the gitweb project + "summary" page inside `<div>` block element. You can use it for longer + description of a project, to provide links (for example to project's + homepage), etc. This is recognized only if XSS prevention is off + (`$prevent_xss` is false, see linkgit:gitweb.conf[5]); a way to include + a README safely when XSS prevention is on may be worked out in the + future. + +description (or `gitweb.description`):: + Short (shortened to `$projects_list_description_width` in the projects + list page, which is 25 characters by default; see + linkgit:gitweb.conf[5]) single line description of a project (of a + repository). Plain text file; HTML will be escaped. By default set to ++ +------------------------------------------------------------------------------- +Unnamed repository; edit this file to name it for gitweb. +------------------------------------------------------------------------------- ++ +from the template during repository creation, usually installed in +'/usr/share/git-core/templates/'. You can use the `gitweb.description` repo +configuration variable, but the file takes precedence. + +category (or `gitweb.category`):: + Singe line category of a project, used to group projects if + `$projects_list_group_categories` is enabled. By default (file and + configuration variable absent), uncategorized projects are put in the + `$project_list_default_category` category. You can use the + `gitweb.category` repo configuration variable, but the file takes + precedence. ++ +The configuration variables `$projects_list_group_categories` and +`$project_list_default_category` are described in linkgit:gitweb.conf[5] + +cloneurl (or multiple-valued `gitweb.url`):: + File with repository URL (used for clone and fetch), one per line. + Displayed in the project summary page. You can use multiple-valued + `gitweb.url` repository configuration variable for that, but the file + takes precedence. ++ +This is per-repository enhancement / version of global prefix-based +`@git_base_url_list` gitweb configuration variable (see +linkgit:gitweb.conf[5]). + +gitweb.owner:: + You can use the `gitweb.owner` repository configuration variable to set + repository's owner. It is displayed in the project list and summary + page. ++ +If it's not set, filesystem directory's owner is used (via GECOS field, +i.e. real name field from *getpwuid*(3)) if `$projects_list` is unset +(gitweb scans `$projectroot` for repositories); if `$projects_list` +points to file with list of repositories, then project owner defaults to +value from this file for given repository. + +various `gitweb.*` config variables (in config):: + Read description of `%feature` hash for detailed list, and descriptions. + See also "Configuring gitweb features" section in linkgit:gitweb.conf[5] + + +ACTIONS, AND URLS +----------------- +Gitweb can use path_info (component) based URLs, or it can pass all necessary +information via query parameters. The typical gitweb URLs are broken down in to +five components: + +----------------------------------------------------------------------- +.../gitweb.cgi/<repo>/<action>/<revision>:/<path>?<arguments> +----------------------------------------------------------------------- + +repo:: + The repository the action will be performed on. ++ +All actions except for those that list all available projects, +in whatever form, require this parameter. + +action:: + The action that will be run. Defaults to 'projects_list' if repo + is not set, and to 'summary' otherwise. + +revision:: + Revision shown. Defaults to HEAD. + +path:: + The path within the <repository> that the action is performed on, + for those actions that require it. + +arguments:: + Any arguments that control the behaviour of the action. + +Some actions require or allow to specify two revisions, and sometimes even two +pathnames. In most general form such path_info (component) based gitweb URL +looks like this: + +----------------------------------------------------------------------- +.../gitweb.cgi/<repo>/<action>/<revision_from>:/<path_from>..<revision_to>:/<path_to>?<arguments> +----------------------------------------------------------------------- + + +Each action is implemented as a subroutine, and must be present in %actions +hash. Some actions are disabled by default, and must be turned on via feature +mechanism. For example to enable 'blame' view add the following to gitweb +configuration file: + +----------------------------------------------------------------------- +$feature{'blame'}{'default'} = [1]; +----------------------------------------------------------------------- + + +Actions: +~~~~~~~~ +The standard actions are: + +project_list:: + Lists the available Git repositories. This is the default command if no + repository is specified in the URL. + +summary:: + Displays summary about given repository. This is the default command if + no action is specified in URL, and only repository is specified. + +heads:: +remotes:: + Lists all local or all remote-tracking branches in given repository. ++ +The latter is not available by default, unless configured. + +tags:: + List all tags (lightweight and annotated) in given repository. + +blob:: +tree:: + Shows the files and directories in a given repository path, at given + revision. This is default command if no action is specified in the URL, + and path is given. + +blob_plain:: + Returns the raw data for the file in given repository, at given path and + revision. Links to this action are marked 'raw'. + +blobdiff:: + Shows the difference between two revisions of the same file. + +blame:: +blame_incremental:: + Shows the blame (also called annotation) information for a file. On a + per line basis it shows the revision in which that line was last changed + and the user that committed the change. The incremental version (which + if configured is used automatically when JavaScript is enabled) uses + Ajax to incrementally add blame info to the contents of given file. ++ +This action is disabled by default for performance reasons. + +commit:: +commitdiff:: + Shows information about a specific commit in a repository. The 'commit' + view shows information about commit in more detail, the 'commitdiff' + action shows changeset for given commit. + +patch:: + Returns the commit in plain text mail format, suitable for applying with + linkgit:git-am[1]. + +tag:: + Display specific annotated tag (tag object). + +log:: +shortlog:: + Shows log information (commit message or just commit subject) for a + given branch (starting from given revision). ++ +The 'shortlog' view is more compact; it shows one commit per line. + +history:: + Shows history of the file or directory in a given repository path, + starting from given revision (defaults to HEAD, i.e. default branch). ++ +This view is similar to 'shortlog' view. + +rss:: +atom:: + Generates an RSS (or Atom) feed of changes to repository. + + +WEBSERVER CONFIGURATION +----------------------- +This section explains how to configure some common webservers to run gitweb. In +all cases, `/path/to/gitweb` in the examples is the directory you ran installed +gitweb in, and contains `gitweb_config.perl`. + +If you've configured a web server that isn't listed here for gitweb, please send +in the instructions so they can be included in a future release. + +Apache as CGI +~~~~~~~~~~~~~ +Apache must be configured to support CGI scripts in the directory in +which gitweb is installed. Let's assume that it is '/var/www/cgi-bin' +directory. + +----------------------------------------------------------------------- +ScriptAlias /cgi-bin/ "/var/www/cgi-bin/" + +<Directory "/var/www/cgi-bin"> + Options Indexes FollowSymlinks ExecCGI + AllowOverride None + Order allow,deny + Allow from all +</Directory> +----------------------------------------------------------------------- + +With that configuration the full path to browse repositories would be: + + http://server/cgi-bin/gitweb.cgi + +Apache with mod_perl, via ModPerl::Registry +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +You can use mod_perl with gitweb. You must install Apache::Registry +(for mod_perl 1.x) or ModPerl::Registry (for mod_perl 2.x) to enable +this support. + +Assuming that gitweb is installed to '/var/www/perl', the following +Apache configuration (for mod_perl 2.x) is suitable. + +----------------------------------------------------------------------- +Alias /perl "/var/www/perl" + +<Directory "/var/www/perl"> + SetHandler perl-script + PerlResponseHandler ModPerl::Registry + PerlOptions +ParseHeaders + Options Indexes FollowSymlinks +ExecCGI + AllowOverride None + Order allow,deny + Allow from all +</Directory> +----------------------------------------------------------------------- + +With that configuration the full path to browse repositories would be: + + http://server/perl/gitweb.cgi + +Apache with FastCGI +~~~~~~~~~~~~~~~~~~~ +Gitweb works with Apache and FastCGI. First you need to rename, copy +or symlink gitweb.cgi to gitweb.fcgi. Let's assume that gitweb is +installed in '/usr/share/gitweb' directory. The following Apache +configuration is suitable (UNTESTED!) + +----------------------------------------------------------------------- +FastCgiServer /usr/share/gitweb/gitweb.cgi +ScriptAlias /gitweb /usr/share/gitweb/gitweb.cgi + +Alias /gitweb/static /usr/share/gitweb/static +<Directory /usr/share/gitweb/static> + SetHandler default-handler +</Directory> +----------------------------------------------------------------------- + +With that configuration the full path to browse repositories would be: + + http://server/gitweb + + +ADVANCED WEB SERVER SETUP +------------------------- +All of those examples use request rewriting, and need `mod_rewrite` +(or equivalent; examples below are written for Apache). + +Single URL for gitweb and for fetching +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +If you want to have one URL for both gitweb and your `http://` +repositories, you can configure Apache like this: + +----------------------------------------------------------------------- +<VirtualHost *:80> + ServerName git.example.org + DocumentRoot /pub/git + SetEnv GITWEB_CONFIG /etc/gitweb.conf + + # turning on mod rewrite + RewriteEngine on + + # make the front page an internal rewrite to the gitweb script + RewriteRule ^/$ /cgi-bin/gitweb.cgi + + # make access for "dumb clients" work + RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ \ + /cgi-bin/gitweb.cgi%{REQUEST_URI} [L,PT] +</VirtualHost> +----------------------------------------------------------------------- + +The above configuration expects your public repositories to live under +'/pub/git' and will serve them as `http://git.domain.org/dir-under-pub-git`, +both as cloneable GIT URL and as browseable gitweb interface. If you then +start your linkgit:git-daemon[1] with `--base-path=/pub/git --export-all` +then you can even use the `git://` URL with exactly the same path. + +Setting the environment variable `GITWEB_CONFIG` will tell gitweb to use the +named file (i.e. in this example '/etc/gitweb.conf') as a configuration for +gitweb. You don't really need it in above example; it is required only if +your configuration file is in different place than built-in (during +compiling gitweb) 'gitweb_config.perl' or '/etc/gitweb.conf'.

First, each unix user (`<user>`) of +the server will be able to browse through gitweb git repositories found in +'~/public_git/' with the following url: + + http://git.example.org/~<user>/ + +If you do not want this feature on your server just remove the second +rewrite rule. + +If you already use `mod_userdir` in your virtual host or you don't want to +use the \'~' as first character, just comment or remove the second rewrite +rule, and uncomment one of the following according to what you want. + +Second, repositories found in '/pub/scm/' and '/var/git/' will be accessible +through `http://git.example.org/scm/` and `http://git.example.org/var/`. +You can add as many project roots as you want by adding rewrite rules like +the third and the fourth. + + +PATH_INFO usage +~~~~~~~~~~~~~~~ +If you enable PATH_INFO usage in gitweb by putting +---------------------------------------------------------------------------- +$feature{'pathinfo'}{'default'} = [1]; +---------------------------------------------------------------------------- +in your gitweb configuration file, it is possible to set up your server so +that it consumes and produces URLs in the form + + http://git.example.com/project.git/shortlog/sometag + +i.e. without 'gitweb.cgi' part, by using a configuration such as the +following. This configuration assumes that '/var/www/gitweb' is the +DocumentRoot of your webserver, contains the gitweb.cgi script and +complementary static files (stylesheet, favicon, JavaScript): + +---------------------------------------------------------------------------- +<VirtualHost *:80> + ServerAlias git.example.com + + DocumentRoot /var/www/gitweb + + <Directory /var/www/gitweb> + Options ExecCGI + AddHandler cgi-script cgi + + DirectoryIndex gitweb.cgi + + RewriteEngine On + RewriteCond %{REQUEST_FILENAME} !-f + RewriteCond %{REQUEST_FILENAME} !-d + RewriteRule ^.* /gitweb.cgi/$0 [L,PT] + </Directory> +</VirtualHost> +---------------------------------------------------------------------------- +The rewrite rule guarantees that existing static files will be properly +served, whereas any other URL will be passed to gitweb as PATH_INFO +parameter. + +*Notice* that in this case you don't need special settings for +`@stylesheets`, `$my_uri` and `$home_link`, but you lose "dumb client" +access to your project .git dirs (described in "Single URL for gitweb and +for fetching" section). A possible workaround for the latter is the +following: in your project root dir (e.g. '/pub/git') have the projects +named *without* a .git extension (e.g. '/pub/git/project' instead of +'/pub/git/project.git') and configure Apache as follows: +---------------------------------------------------------------------------- +<VirtualHost *:80> + ServerAlias git.example.com + + DocumentRoot /var/www/gitweb + + AliasMatch ^(/.*?)(\.git)(/.*)?$ /pub/git$1$3 + <Directory /var/www/gitweb> + Options ExecCGI + AddHandler cgi-script cgi + + DirectoryIndex gitweb.cgi + + RewriteEngine On + RewriteCond %{REQUEST_FILENAME} !-f + RewriteCond %{REQUEST_FILENAME} !-d + RewriteRule ^.* /gitweb.cgi/$0 [L,PT] + </Directory> +</VirtualHost> +---------------------------------------------------------------------------- + +The additional AliasMatch makes it so that + + http://git.example.com/project.git + +will give raw access to the project's git dir (so that the project can be +cloned), while + + http://git.example.com/project + +will provide human-friendly gitweb access. + +This solution is not 100% bulletproof, in the sense that if some project has +a named ref (branch, tag) starting with 'git/', then paths such as + + http://git.example.com/project/command/abranch..git/abranch + +will fail with a 404 error. + + +BUGS +---- +Please report any bugs or feature requests to git@vger.kernel.org, +putting "gitweb" in the subject of email. + +SEE ALSO +-------- +linkgit:gitweb.conf[5], linkgit:git-instaweb[1] + +'gitweb/README', 'gitweb/INSTALL' + +GIT +--- +Part of the linkgit:git[1] suite diff --git a/Documentation/merge-options.txt b/Documentation/merge-options.txt index b613d4ed08..1a5c12e317 100644 --- a/Documentation/merge-options.txt +++ b/Documentation/merge-options.txt @@ -7,6 +7,11 @@ With --no-commit perform the merge but pretend the merge failed and do not autocommit, to give the user a chance to inspect and further tweak the merge result before committing. +--edit:: +-e:: + Invoke editor before committing successful merge to further + edit the default merge message. + --ff:: --no-ff:: Do not generate a merge commit if the merge resolved as diff --git a/Documentation/sequencer.txt b/Documentation/sequencer.txt new file mode 100644 index 0000000000..5747f442f2 --- /dev/null +++ b/Documentation/sequencer.txt @@ -0,0 +1,12 @@ +--continue:: + Continue the operation in progress using the information in + '.git/sequencer'.

Sometimes, though, when an old line and a new line are very +similar, it's hard to immediately see the difference. + +You can use "--color-words" to highlight only the changed portions of +lines. However, this can often be hard to read for code, as it loses +the line structure, and you end up with oddly formatted bits. + +Instead, this script post-processes the line-oriented diff, finds pairs +of lines, and highlights the differing segments. It's currently very +simple and stupid about doing these tasks. In particular: + + 1. It will only highlight a pair of lines if they are the only two + lines in a hunk. It could instead try to match up "before" and + "after" lines for a given hunk into pairs of similar lines. + However, this may end up visually distracting, as the paired + lines would have other highlighted lines in between them. And in + practice, the lines which most need attention called to their + small, hard-to-see changes are touching only a single line. + + 2. It will find the common prefix and suffix of two lines, and + consider everything in the middle to be "different". It could + instead do a real diff of the characters between the two lines and + find common subsequences. However, the point of the highlight is to + call attention to a certain area. Even if some small subset of the + highlighted area actually didn't change, that's OK. In practice it + ends up being more readable to just have a single blob on the line + showing the interesting bit. + +The goal of the script is therefore not to be exact about highlighting +changes, but to call attention to areas of interest without being +visually distracting.

For example, given a diff like this: + +------------------------------------ +diff --git a/foo.c b/foo.c +index a655540..5a59044 100644 +--- a/foo.c ++++ b/foo.c +@@ -1,3 +1,3 @@ + int main(void) { +- printf("hello word!\n"); ++ printf("hello world!\n"); + } +----------------------------------- + +git-jump will feed this to the editor: + +----------------------------------- +foo.c:2: printf("hello word!\n"); +----------------------------------- + +Obviously this trivial case isn't that interesting; you could just open +`foo.c` yourself. But when you have many changes scattered across a +project, you can use the editor's support to "jump" from point to point. + +Git-jump can generate three types of interesting lists: + + 1. The beginning of any diff hunks. + + 2. The beginning of any merge conflict markers. + + 3. Any grep matches. + + +Using git-jump +-------------- + +To use it, just drop git-jump in your PATH, and then invoke it like +this: + +-------------------------------------------------- +# jump to changes not yet staged for commit +git jump diff + +# jump to changes that are staged for commit; you can give +# arbitrary diff options +git jump diff --cached + +# jump to merge conflicts +git jump merge + +# jump to all instances of foo_bar +git jump grep foo_bar + +# same as above, but case-insensitive; you can give +# arbitrary grep options +git jump grep -i foo_bar +-------------------------------------------------- + + +Related Programs +---------------- + +You can accomplish some of the same things with individual tools. For +example, you can use `git mergetool` to start vimdiff on each unmerged +file. `git jump merge` is for the vim-wielding luddite who just wants to +jump straight to the conflict text with no fanfare. + +As of git v1.7.2, `git grep` knows the `--open-files-in-pager` option, +which does something similar to `git jump grep`. However, it is limited +to positioning the cursor to the correct line in only the first file, +leaving you to locate subsequent hits in that file or other files using +the editor or pager. By contrast, git-jump provides the editor with a +complete list of files and line numbers for each match. + + +Limitations +----------- + +This scripts was written and tested with vim. Given that the quickfix +format is the same as what gcc produces, I expect emacs users have a +similar feature for iterating through the list, but I know nothing about +how to activate it. + +The shell snippets to generate the quickfix lines will almost certainly +choke on filenames with exotic characters (like newlines). diff --git a/contrib/git-jump/git-jump b/contrib/git-jump/git-jump new file mode 100755 index 0000000000..a33674e47a --- /dev/null +++ b/contrib/git-jump/git-jump @@ -0,0 +1,69 @@ +#!/bin/sh + +usage() { + cat <<\EOF +usage: git jump <mode> [<args>] + +Jump to interesting elements in an editor. +The <mode> parameter is one of: + +diff: elements are diff hunks.

Set to - $GITWEB_LIST during installation.

See - $per_request_config if you need to set them still. - * $base_url - Base URL for relative URLs in pages generated by gitweb, - (e.g. $logo, $favicon, @stylesheets if they are relative URLs), - needed and used only for URLs with nonempty PATH_INFO via - <base href="$base_url">. Usually gitweb sets its value correctly, - and there is no need to set this variable, e.g. to $my_uri or "/". - See $per_request_config if you need to set it anyway. - * $home_link - Target of the home link on top of all pages (the first part of view - "breadcrumbs"). By default set to absolute URI of a page ($my_uri). - * @stylesheets - List of URIs of stylesheets (relative to base URI of a page). You - might specify more than one stylesheet, for example use gitweb.css - as base, with site specific modifications in separate stylesheet - to make it easier to upgrade gitweb. You can add 'site' stylesheet - for example by using - push @stylesheets, "gitweb-site.css"; - in the gitweb config file. - * $logo_url, $logo_label - URI and label (title) of GIT logo link (or your site logo, if you choose - to use different logo image). By default they point to git homepage; - in the past they pointed to git documentation at www.kernel.org. - * $projects_list_description_width - The width (in characters) of the projects list "Description" column. - Longer descriptions will be cut (trying to cut at word boundary); - full description is available as 'title' attribute (usually shown on - mouseover). By default set to 25, which might be too small if you - use long project descriptions. - * $projects_list_group_categories - Enables the grouping of projects by category on the project list page. - The category of a project is determined by the $GIT_DIR/category - file or the 'gitweb.category' variable in its repository configuration. - Disabled by default. - * $project_list_default_category - Default category for projects for which none is specified. If set - to the empty string, such projects will remain uncategorized and - listed at the top, above categorized projects. - * @git_base_url_list - List of git base URLs used for URL to where fetch project from, shown - in project summary page. Full URL is "$git_base_url/$project". - You can setup multiple base URLs (for example one for git:// protocol - access, and one for http:// "dumb" protocol access). Note that per - repository configuration in 'cloneurl' file, or as values of gitweb.url - project config. - * $default_blob_plain_mimetype - Default mimetype for blob_plain (raw) view, if mimetype checking - doesn't result in some other type; by default 'text/plain'. - * $default_text_plain_charset - Default charset for text files. If not set, web server configuration - would be used. - * $mimetypes_file - File to use for (filename extension based) guessing of MIME types before - trying /etc/mime.types. Path, if relative, is taken currently as - relative to the current git repository. - * $fallback_encoding - Gitweb assumes this charset if line contains non-UTF-8 characters. - Fallback decoding is used without error checking, so it can be even - 'utf-8'. Value must be valid encoding; see Encoding::Supported(3pm) man - page for a list. By default 'latin1', aka. 'iso-8859-1'. - * @diff_opts - Rename detection options for git-diff and git-diff-tree. By default - ('-M'); set it to ('-C') or ('-C', '-C') to also detect copies, or - set it to () if you don't want to have renames detection. - * $prevent_xss - If true, some gitweb features are disabled to prevent content in - repositories from launching cross-site scripting (XSS) attacks. Set this - to true if you don't trust the content of your repositories. The default - is false. - * $maxload - Used to set the maximum load that we will still respond to gitweb queries. - If server load exceed this value then return "503 Service Unavailable" error. - Server load is taken to be 0 if gitweb cannot determine its value. Set it to - undefined value to turn it off. The default is 300. - * $highlight_bin - Path to the highlight executable to use (must be the one from - http://www.andre-simon.de due to assumptions about parameters and output). - Useful if highlight is not installed on your webserver's PATH. - [Default: highlight] - * $per_request_config - If set to code reference, it would be run once per each request. You can - set parts of configuration that change per session, e.g. by setting it to - sub { $ENV{GL_USER} = $cgi->remote_user || "gitweb"; } - Otherwise it is treated as boolean value: if true gitweb would process - config file once per request, if false it would process config file only - once. Note: $my_url, $my_uri, and $base_url are overwritten with - their default values before every request, so if you want to change - them, be sure to set this variable to true or a code reference effecting - the desired changes. The default is true. - -Projects list file format -~~~~~~~~~~~~~~~~~~~~~~~~~ - -Instead of having gitweb find repositories by scanning filesystem starting -from $projectroot (or $projects_list, if it points to directory), you can -provide list of projects by setting $projects_list to a text file with list -of projects (and some additional info). This file uses the following -format: - -One record (for project / repository) per line, whitespace separated fields; -does not support (at least for now) lines continuation (newline escaping). -Leading and trailing whitespace are ignored, any run of whitespace can be -used as field separator (rules for Perl's "split(' ', $line)"). Keyed by -the first field, which is project name, i.e. path to repository GIT_DIR -relative to $projectroot. Fields use modified URI encoding, defined in -RFC 3986, section 2.1 (Percent-Encoding), or rather "Query string encoding" -(see http://en.wikipedia.org/wiki/Query_string#URL_encoding), the difference -being that SP (' ') can be encoded as '+' (and therefore '+' has to be also -percent-encoded). Reserved characters are: '%' (used for encoding), '+' -(can be used to encode SPACE), all whitespace characters as defined in Perl, -including SP, TAB and LF, (used to separate fields in a record). - -Currently list of fields is - * <repository path> - path to repository GIT_DIR, relative to $projectroot - * <repository owner> - displayed as repository owner, preferably full name, - or email, or both - -You can additionally use $projects_list file to limit which repositories -are visible, and together with $strict_export to limit access to -repositories (see "Gitweb repositories" section in gitweb/INSTALL). - - -Per-repository gitweb configuration -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -You can also configure individual repositories shown in gitweb by creating -file in the GIT_DIR of git repository, or by setting some repo configuration -variable (in GIT_DIR/config). - -You can use the following files in repository: - * README.html - A .html file (HTML fragment) which is included on the gitweb project - summary page inside <div> block element. You can use it for longer - description of a project, to provide links (for example to project's - homepage), etc. This is recognized only if XSS prevention is off - ($prevent_xss is false); a way to include a readme safely when XSS - prevention is on may be worked out in the future. - * description (or gitweb.description) - Short (shortened by default to 25 characters in the projects list page) - single line description of a project (of a repository). Plain text file; - HTML will be escaped. By default set to - Unnamed repository; edit this file to name it for gitweb. - from the template during repository creation. You can use the - gitweb.description repo configuration variable, but the file takes - precedence. - * category (or gitweb.category) - Singe line category of a project, used to group projects if - $projects_list_group_categories is enabled. By default (file and - configuration variable absent), uncategorized projects are put in - the $project_list_default_category category. You can use the - gitweb.category repo configuration variable, but the file takes - precedence. - * cloneurl (or multiple-valued gitweb.url) - File with repository URL (used for clone and fetch), one per line. - Displayed in the project summary page. You can use multiple-valued - gitweb.url repository configuration variable for that, but the file - takes precedence. - * gitweb.owner - You can use the gitweb.owner repository configuration variable to set - repository's owner. It is displayed in the project list and summary - page. If it's not set, filesystem directory's owner is used - (via GECOS field / real name field from getpwiud(3)). - * various gitweb.* config variables (in config) - Read description of %feature hash for detailed list, and some - descriptions. - - -Webserver configuration ------------------------ - -If you want to have one URL for both gitweb and your http:// -repositories, you can configure apache like this: - -<VirtualHost *:80> - ServerName git.example.org - DocumentRoot /pub/git - SetEnv GITWEB_CONFIG /etc/gitweb.conf - - # turning on mod rewrite - RewriteEngine on - - # make the front page an internal rewrite to the gitweb script - RewriteRule ^/$ /cgi-bin/gitweb.cgi - - # make access for "dumb clients" work - RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ /cgi-bin/gitweb.cgi%{REQUEST_URI} [L,PT] -</VirtualHost> - -The above configuration expects your public repositories to live under -/pub/git and will serve them as http://git.domain.org/dir-under-pub-git, -both as cloneable GIT URL and as browseable gitweb interface. -If you then start your git-daemon with --base-path=/pub/git --export-all -then you can even use the git:// URL with exactly the same path. - -Setting the environment variable GITWEB_CONFIG will tell gitweb to use -the named file (i.e. in this example /etc/gitweb.conf) as a -configuration for gitweb.
