CONFIGURATION FILE ------------------ The Git configuration file contains a number of variables that affect the Git commands' behavior. The files `.git/config` and optionally `config.worktree` (see `extensions.worktreeConfig` below) in each repository are used to store the configuration for that repository, and `$HOME/.gitconfig` is used to store a per-user configuration as fallback values for the `.git/config` file. The file `/etc/gitconfig` can be used to store a system-wide default configuration. The configuration variables are used by both the Git plumbing and the porcelains. The variables are divided into sections, wherein the fully qualified variable name of the variable itself is the last dot-separated segment and the section name is everything before the last dot. The variable names are case-insensitive, allow only alphanumeric characters and `-`, and must start with an alphabetic character. Some variables may appear multiple times; we say then that the variable is multivalued. Syntax ~~~~~~ The syntax is fairly flexible and permissive; whitespaces are mostly ignored. The '#' and ';' characters begin comments to the end of line, blank lines are ignored. The file consists of sections and variables. A section begins with the name of the section in square brackets and continues until the next section begins. Section names are case-insensitive. Only alphanumeric characters, `-` and `.` are allowed in section names. Each variable must belong to some section, which means that there must be a section header before the first setting of a variable. Sections can be further divided into subsections. To begin a subsection put its name in double quotes, separated by space from the section name, in the section header, like in the example below: -------- [section "subsection"] -------- Subsection names are case sensitive and can contain any characters except newline and the null byte. Doublequote `"` and backslash can be included by escaping them as `\"` and `\\`, respectively. Backslashes preceding other characters are dropped when reading; for example, `\t` is read as `t` and `\0` is read as `0` Section headers cannot span multiple lines. Variables may belong directly to a section or to a given subsection. You can have `[section]` if you have `[section "subsection"]`, but you don't need to. There is also a deprecated `[section.subsection]` syntax. With this syntax, the subsection name is converted to lower-case and is also compared case sensitively. These subsection names follow the same restrictions as section names. All the other lines (and the remainder of the line after the section header) are recognized as setting variables, in the form 'name = value' (or just 'name', which is a short-hand to say that the variable is the boolean "true"). The variable names are case-insensitive, allow only alphanumeric characters and `-`, and must start with an alphabetic character. A line that defines a value can be continued to the next line by ending it with a `\`; the backquote and the end-of-line are stripped. Leading whitespaces after 'name =', the remainder of the line after the first comment character '#' or ';', and trailing whitespaces of the line are discarded unless they are enclosed in double quotes. Internal whitespaces within the value are retained verbatim. Inside double quotes, double quote `"` and backslash `\` characters must be escaped: use `\"` for `"` and `\\` for `\`. The following escape sequences (beside `\"` and `\\`) are recognized: `\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB) and `\b` for backspace (BS). Other char escape sequences (including octal escape sequences) are invalid. Includes ~~~~~~~~ The `include` and `includeIf` sections allow you to include config directives from another source. These sections behave identically to each other with the exception that `includeIf` sections may be ignored if their condition does not evaluate to true; see "Conditional includes" below. You can include a config file from another by setting the special `include.path` (or `includeIf.*.path`) variable to the name of the file to be included. The variable takes a pathname as its value, and is subject to tilde expansion. These variables can be given multiple times. The contents of the included file are inserted immediately, as if they had been found at the location of the include directive. If the value of the variable is a relative path, the path is considered to be relative to the configuration file in which the include directive was found. See below for examples. Conditional includes ~~~~~~~~~~~~~~~~~~~~ You can include a config file from another conditionally by setting a `includeIf..path` variable to the name of the file to be included. The condition starts with a keyword followed by a colon and some data whose format and meaning depends on the keyword. Supported keywords are: `gitdir`:: The data that follows the keyword `gitdir:` is used as a glob pattern. If the location of the .git directory matches the pattern, the include condition is met. + The .git location may be auto-discovered, or come from `$GIT_DIR` environment variable. If the repository is auto discovered via a .git file (e.g. from submodules, or a linked worktree), the .git location would be the final location where the .git directory is, not where the .git file is. + The pattern can contain standard globbing wildcards and two additional ones, `**/` and `/**`, that can match multiple path components. Please refer to linkgit:gitignore[5] for details. For convenience: * If the pattern starts with `~/`, `~` will be substituted with the content of the environment variable `HOME`. * If the pattern starts with `./`, it is replaced with the directory containing the current config file. * If the pattern does not start with either `~/`, `./` or `/`, `**/` will be automatically prepended. For example, the pattern `foo/bar` becomes `**/foo/bar` and would match `/any/path/to/foo/bar`. * If the pattern ends with `/`, `**` will be automatically added. For example, the pattern `foo/` becomes `foo/**`. In other words, it matches "foo" and everything inside, recursively. `gitdir/i`:: This is the same as `gitdir` except that matching is done case-insensitively (e.g. on case-insensitive file sytems) A few more notes on matching via `gitdir` and `gitdir/i`: * Symlinks in `$GIT_DIR` are not resolved before matching. * Both the symlink & realpath versions of paths will be matched outside of `$GIT_DIR`. E.g. if ~/git is a symlink to /mnt/storage/git, both `gitdir:~/git` and `gitdir:/mnt/storage/git` will match. + This was not the case in the initial release of this feature in v2.13.0, which only matched the realpath version. Configuration that wants to be compatible with the initial release of this feature needs to either specify only the realpath version, or both versions. * Note that "../" is not special and will match literally, which is unlikely what you want. Example ~~~~~~~ # Core variables [core] ; Don't trust file modes filemode = false # Our diff algorithm [diff] external = /usr/local/bin/diff-wrapper renames = true [branch "devel"] remote = origin merge = refs/heads/devel # Proxy settings [core] gitProxy="ssh" for "kernel.org" gitProxy=default-proxy ; for the rest [include] path = /path/to/foo.inc ; include by absolute path path = foo.inc ; find "foo.inc" relative to the current file path = ~/foo.inc ; find "foo.inc" in your `$HOME` directory ; include if $GIT_DIR is /path/to/foo/.git [includeIf "gitdir:/path/to/foo/.git"] path = /path/to/foo.inc ; include for all repositories inside /path/to/group [includeIf "gitdir:/path/to/group/"] path = /path/to/foo.inc ; include for all repositories inside $HOME/to/group [includeIf "gitdir:~/to/group/"] path = /path/to/foo.inc ; relative paths are always relative to the including ; file (if the condition is true); their location is not ; affected by the condition [includeIf "gitdir:/path/to/group/"] path = foo.inc Values ~~~~~~ Values of many variables are treated as a simple string, but there are variables that take values of specific types and there are rules as to how to spell them. boolean:: When a variable is said to take a boolean value, many synonyms are accepted for 'true' and 'false'; these are all case-insensitive. true;; Boolean true literals are `yes`, `on`, `true`, and `1`. Also, a variable defined without `= ` is taken as true. false;; Boolean false literals are `no`, `off`, `false`, `0` and the empty string. + When converting a value to its canonical form using the `--type=bool` type specifier, 'git config' will ensure that the output is "true" or "false" (spelled in lowercase). integer:: The value for many variables that specify various sizes can be suffixed with `k`, `M`,... to mean "scale the number by 1024", "by 1024x1024", etc. color:: The value for a variable that takes a color is a list of colors (at most two, one for foreground and one for background) and attributes (as many as you want), separated by spaces. + The basic colors accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan` and `white`. The first color given is the foreground; the second is the background. + Colors may also be given as numbers between 0 and 255; these use ANSI 256-color mode (but note that not all terminals may support this). If your terminal supports it, you may also specify 24-bit RGB values as hex, like `#ff0ab3`. + The accepted attributes are `bold`, `dim`, `ul`, `blink`, `reverse`, `italic`, and `strike` (for crossed-out or "strikethrough" letters). The position of any attributes with respect to the colors (before, after, or in between), doesn't matter. Specific attributes may be turned off by prefixing them with `no` or `no-` (e.g., `noreverse`, `no-ul`, etc). + An empty color string produces no color effect at all. This can be used to avoid coloring specific elements without disabling color entirely. + For git's pre-defined color slots, the attributes are meant to be reset at the beginning of each item in the colored output. So setting `color.decorate.branch` to `black` will paint that branch name in a plain `black`, even if the previous thing on the same output line (e.g. opening parenthesis before the list of branch names in `log --decorate` output) is set to be painted with `bold` or some other attribute. However, custom log formats may do more complicated and layered coloring, and the negated forms may be useful there. pathname:: A variable that takes a pathname value can be given a string that begins with "`~/`" or "`~user/`", and the usual tilde expansion happens to such a string: `~/` is expanded to the value of `$HOME`, and `~user/` to the specified user's home directory. Variables ~~~~~~~~~ Note that this list is non-comprehensive and not necessarily complete. For command-specific variables, you will find a more detailed description in the appropriate manual page. Other git-related tools may and do use their own variables. When inventing new variables for use in your own tool, make sure their names do not conflict with those that are used by Git itself and other popular tools, and describe them in your documentation. include::config/advice.txt[] include::config/core.txt[] include::config/add.txt[] include::config/alias.txt[] include::config/am.txt[] include::config/apply.txt[] include::config/blame.txt[] include::config/branch.txt[] include::config/browser.txt[] include::config/checkout.txt[] include::config/clean.txt[] include::config/color.txt[] include::config/column.txt[] include::config/commit.txt[] include::config/credential.txt[] include::config/completion.txt[] include::config/diff.txt[] include::config/difftool.txt[] include::config/fastimport.txt[] include::config/fetch.txt[] include::config/format.txt[] include::config/filter.txt[] include::config/fsck.txt[] include::config/gc.txt[] include::config/gitcvs.txt[] include::config/gitweb.txt[] include::config/grep.txt[] include::config/gpg.txt[] include::config/gui.txt[] include::config/guitool.txt[] include::config/help.txt[] include::config/http.txt[] include::config/i18n.txt[] include::config/imap.txt[] include::config/index.txt[] include::config/init.txt[] include::config/instaweb.txt[] include::config/interactive.txt[] include::config/log.txt[] include::config/mailinfo.txt[] include::config/mailmap.txt[] include::config/man.txt[] include::config/merge.txt[] include::config/mergetool.txt[] include::config/notes.txt[] include::config/pack.txt[] include::config/pager.txt[] include::config/pretty.txt[] include::config/protocol.txt[] include::config/pull.txt[] include::config/push.txt[] include::config/rebase.txt[] include::config/receive.txt[] include::config/remote.txt[] include::config/remotes.txt[] include::config/repack.txt[] include::config/rerere.txt[] include::config/reset.txt[] include::config/sendemail.txt[] include::config/sequencer.txt[] include::config/showbranch.txt[] include::config/splitindex.txt[] include::config/ssh.txt[] include::config/status.txt[] include::config/stash.txt[] include::config/submodule.txt[] include::config/tag.txt[] include::config/trace2.txt[] include::config/transfer.txt[] include::config/uploadarchive.txt[] include::config/uploadpack.txt[] include::config/url.txt[] include::config/user.txt[] include::config/versionsort.txt[] include::config/web.txt[] include::config/worktree.txt[]
