config.txt

CONFIGURATION FILE
------------------

The Git configuration file contains a number of variables that affect
the Git commands' behavior. The `.git/config` file in each repository
is 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 (doublequote `"` and backslash can be included by escaping them
as `\"` and `\\`, respectively).  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
~~~~~~~~

You can include a config file from another by setting the special
`include.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. `include.path` can be given multiple times.

The included file is expanded immediately, as if its contents had been
found at the location of the include directive. If the value of the
`include.path` 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.<condition>.path` variable to the name of the file to be
included. The variable's value is treated the same way as
`include.path`. `includeIf.<condition>.path` can be given multiple times.

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.

 * 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 ; expand "foo" relative to the current file
		path = ~/foo ; expand "foo" 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

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 can be spelled as `yes`, `on`, `true`,
		or `1`.  Also, a variable defined without `= <value>`
		is taken as true.

       false;; Boolean false can be spelled as `no`, `off`,
		`false`, or `0`.
+
When converting value to the canonical form using `--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.


advice.*::
	These variables control various optional help messages designed to
	aid new users. All 'advice.*' variables default to 'true', and you
	can tell Git that you do not need help by setting these to 'false':
+
--
	pushUpdateRejected::
		Set this variable to 'false' if you want to disable
		'pushNonFFCurrent',
		'pushNonFFMatching', 'pushAlreadyExists',
		'pushFetchFirst', and 'pushNeedsForce'
		simultaneously.
	pushNonFFCurrent::
		Advice shown when linkgit:git-push[1] fails due to a
		non-fast-forward update to the current branch.
	pushNonFFMatching::
		Advice shown when you ran linkgit:git-push[1] and pushed
		'matching refs' explicitly (i.e. you used ':', or
		specified a refspec that isn't your current branch) and
		it resulted in a non-fast-forward error.
	pushAlreadyExists::
		Shown when linkgit:git-push[1] rejects an update that
		does not qualify for fast-forwarding (e.g., a tag.)
	pushFetchFirst::
		Shown when linkgit:git-push[1] rejects an update that
		tries to overwrite a remote ref that points at an
		object we do not have.
	pushNeedsForce::
		Shown when linkgit:git-push[1] rejects an update that
		tries to overwrite a remote ref that points at an
		object that is not a commit-ish, or make the remote
		ref point at an object that is not a commit-ish.
	statusHints::
		Show directions on how to proceed from the current
		state in the output of linkgit:git-status[1], in
		the template shown when writing commit messages in
		linkgit:git-commit[1], and in the help message shown
		by linkgit:git-checkout[1] when switching branch.
	statusUoption::
		Advise to consider using the `-u` option to linkgit:git-status[1]
		when the command takes more than 2 seconds to enumerate untracked
		files.
	commitBeforeMerge::
		Advice shown when linkgit:git-merge[1] refuses to
		merge to avoid overwriting local changes.
	resolveConflict::
		Advice shown by various commands when conflicts
		prevent the operation from being performed.
	implicitIdentity::
		Advice on how to set your identity configuration when
		your information is guessed from the system username and
		domain name.
	detachedHead::
		Advice shown when you used linkgit:git-checkout[1] to
		move to the detach HEAD state, to instruct how to create
		a local branch after the fact.
	amWorkDir::
		Advice that shows the location of the patch file when
		linkgit:git-am[1] fails to apply it.
	rmHints::
		In case of failure in the output of linkgit:git-rm[1],
		show directions on how to proceed from the current state.
--

core.fileMode::
	Tells Git if the executable bit of files in the working tree
	is to be honored.
+
Some filesystems lose the executable bit when a file that is
marked as executable is checked out, or checks out an
non-executable file with executable bit on.
linkgit:git-clone[1] or linkgit:git-init[1] probe the filesystem
to see if it handles the executable bit correctly
and this variable is automatically set as necessary.
+
A repository, however, may be on a filesystem that handles
the filemode correctly, and this variable is set to 'true'
when created, but later may be made accessible from another
environment that loses the filemode (e.g. exporting ext4 via
CIFS mount, visiting a Cygwin created repository with
Git for Windows or Eclipse).
In such a case it may be necessary to set this variable to 'false'.
See linkgit:git-update-index[1].
+
The default is true (when core.filemode is not specified in the config file).

core.hideDotFiles::
	(Windows-only) If true, mark newly-created directories and files whose
	name starts with a dot as hidden.  If 'dotGitOnly', only the `.git/`
	directory is hidden, but no other files starting with a dot.  The
	default mode is 'dotGitOnly'.

core.ignoreCase::
	If true, this option enables various workarounds to enable
	Git to work better on filesystems that are not case sensitive,
	like FAT. For example, if a directory listing finds
	"makefile" when Git expects "Makefile", Git will assume
	it is really the same file, and continue to remember it as
	"Makefile".
+
The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
will probe and set core.ignoreCase true if appropriate when the repository
is created.

core.precomposeUnicode::
	This option is only used by Mac OS implementation of Git.
	When core.precomposeUnicode=true, Git reverts the unicode decomposition
	of filenames done by Mac OS. This is useful when sharing a repository
	between Mac OS and Linux or Windows.
	(Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7).
	When false, file names are handled fully transparent by Git,
	which is backward compatible with older versions of Git.

core.protectHFS::
	If set to true, do not allow checkout of paths that would
	be considered equivalent to `.git` on an HFS+ filesystem.
	Defaults to `true` on Mac OS, and `false` elsewhere.

core.protectNTFS::
	If set to true, do not allow checkout of paths that would
	cause problems with the NTFS filesystem, e.g. conflict with
	8.3 "short" names.
	Defaults to `true` on Windows, and `false` elsewhere.

core.trustctime::
	If false, the ctime differences between the index and the
	working tree are ignored; useful when the inode change time
	is regularly modified by something outside Git (file system
	crawlers and some backup systems).
	See linkgit:git-update-index[1]. True by default.

core.splitIndex::
	If true, the split-index feature of the index will be used.
	See linkgit:git-update-index[1]. False by default.

core.untrackedCache::
	Determines what to do about the untracked cache feature of the
	index. It will be kept, if this variable is unset or set to
	`keep`. It will automatically be added if set to `true`. And
	it will automatically be removed, if set to `false`. Before
	setting it to `true`, you should check that mtime is working
	properly on your system.
	See linkgit:git-update-index[1]. `keep` by default.

core.checkStat::
	Determines which stat fields to match between the index
	and work tree. The user can set this to 'default' or
	'minimal'. Default (or explicitly 'default'), is to check
	all fields, including the sub-second part of mtime and ctime.

core.quotePath::
	Commands that output paths (e.g. 'ls-files', 'diff'), will
	quote "unusual" characters in the pathname by enclosing the
	pathname in double-quotes and escaping those characters with
	backslashes in the same way C escapes control characters (e.g.
	`\t` for TAB, `\n` for LF, `\\` for backslash) or bytes with
	values larger than 0x80 (e.g. octal `\302\265` for "micro" in
	UTF-8).  If this variable is set to false, bytes higher than
	0x80 are not considered "unusual" any more. Double-quotes,
	backslash and control characters are always escaped regardless
	of the setting of this variable.  A simple space character is
	not considered "unusual".  Many commands can output pathnames
	completely verbatim using the `-z` option. The default value
	is true.

core.eol::
	Sets the line ending type to use in the working directory for
	files that have the `text` property set when core.autocrlf is false.
	Alternatives are 'lf', 'crlf' and 'native', which uses the platform's
	native line ending.  The default value is `native`.  See
	linkgit:gitattributes[5] for more information on end-of-line
	conversion.

core.safecrlf::
	If true, makes Git check if converting `CRLF` is reversible when
	end-of-line conversion is active.  Git will verify if a command
	modifies a file in the work tree either directly or indirectly.
	For example, committing a file followed by checking out the
	same file should yield the original file in the work tree.  If
	this is not the case for the current setting of
	`core.autocrlf`, Git will reject the file.  The variable can
	be set to "warn", in which case Git will only warn about an
	irreversible conversion but continue the operation.
+
CRLF conversion bears a slight chance of corrupting data.
When it is enabled, Git will convert CRLF to LF during commit and LF to
CRLF during checkout.  A file that contains a mixture of LF and
CRLF before the commit cannot be recreated by Git.  For text
files this is the right thing to do: it corrects line endings
such that we have only LF line endings in the repository.
But for binary files that are accidentally classified as text the
conversion can corrupt data.
+
If you recognize such corruption early you can easily fix it by
setting the conversion type explicitly in .gitattributes.  Right
after committing you still have the original file in your work
tree and this file is not yet corrupted.  You can explicitly tell
Git that this file is binary and Git will handle the file
appropriately.
+
Unfortunately, the desired effect of cleaning up text files with
mixed line endings and the undesired effect of corrupting binary
files cannot be distinguished.  In both cases CRLFs are removed
in an irreversible way.  For text files this is the right thing
to do because CRLFs are line endings, while for binary files
converting CRLFs corrupts data.
+
Note, this safety check does not mean that a checkout will generate a
file identical to the original file for a different setting of
`core.eol` and `core.autocrlf`, but only for the current one.  For
example, a text file with `LF` would be accepted with `core.eol=lf`
and could later be checked out with `core.eol=crlf`, in which case the
resulting file would contain `CRLF`, although the original file
contained `LF`.  However, in both work trees the line endings would be
consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
file with mixed line endings would be reported by the `core.safecrlf`
mechanism.

core.autocrlf::
	Setting this variable to "true" is the same as setting
	the `text` attribute to "auto" on all files and core.eol to "crlf".
	Set to true if you want to have `CRLF` line endings in your
	working directory and the repository has LF line endings.
	This variable can be set to 'input',
	in which case no output conversion is performed.

core.symlinks::
	If false, symbolic links are checked out as small plain files that
	contain the link text. linkgit:git-update-index[1] and
	linkgit:git-add[1] will not change the recorded type to regular
	file. Useful on filesystems like FAT that do not support
	symbolic links.
+
The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
will probe and set core.symlinks false if appropriate when the repository
is created.

core.gitProxy::
	A "proxy command" to execute (as 'command host port') instead
	of establishing direct connection to the remote server when
	using the Git protocol for fetching. If the variable value is
	in the "COMMAND for DOMAIN" format, the command is applied only
	on hostnames ending with the specified domain string. This variable
	may be set multiple times and is matched in the given order;
	the first match wins.
+
Can be overridden by the `GIT_PROXY_COMMAND` environment variable
(which always applies universally, without the special "for"
handling).
+
The special string `none` can be used as the proxy command to
specify that no proxy be used for a given domain pattern.
This is useful for excluding servers inside a firewall from
proxy use, while defaulting to a common proxy for external domains.

core.sshCommand::
	If this variable is set, `git fetch` and `git push` will
	use the specified command instead of `ssh` when they need to
	connect to a remote system. The command is in the same form as
	the `GIT_SSH_COMMAND` environment variable and is overridden
	when the environment variable is set.

core.ignoreStat::
	If true, Git will avoid using lstat() calls to detect if files have
	changed by setting the "assume-unchanged" bit for those tracked files
	which it has updated identically in both the index and working tree.
+
When files are modified outside of Git, the user will need to stage
the modified files explicitly (e.g. see 'Examples' section in
linkgit:git-update-index[1]).
Git will not normally detect changes to those files.
+
This is useful on systems where lstat() calls are very slow, such as
CIFS/Microsoft Windows.
+
False by default.

core.preferSymlinkRefs::
	Instead of the default "symref" format for HEAD
	and other symbolic reference files, use symbolic links.
	This is sometimes needed to work with old scripts that
	expect HEAD to be a symbolic link.

core.bare::
	If true this repository is assumed to be 'bare' and has no
	working directory associated with it.  If this is the case a
	number of commands that require a working directory will be
	disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
+
This setting is automatically guessed by linkgit:git-clone[1] or
linkgit:git-init[1] when the repository was created.  By default a
repository that ends in "/.git" is assumed to be not bare (bare =
false), while all other repositories are assumed to be bare (bare
= true).

core.worktree::
	Set the path to the root of the working tree.
	If `GIT_COMMON_DIR` environment variable is set, core.worktree
	is ignored and not used for determining the root of working tree.
	This can be overridden by the `GIT_WORK_TREE` environment
	variable and the `--work-tree` command-line option.
	The value can be an absolute path or relative to the path to
	the .git directory, which is either specified by --git-dir
	or GIT_DIR, or automatically discovered.
	If --git-dir or GIT_DIR is specified but none of
	--work-tree, GIT_WORK_TREE and core.worktree is specified,
	the current working directory is regarded as the top level
	of your working tree.
+
Note that this variable is honored even when set in a configuration
file in a ".git" subdirectory of a directory and its value differs
from the latter directory (e.g. "/path/to/.git/config" has
core.worktree set to "/different/path"), which is most likely a
misconfiguration.  Running Git commands in the "/path/to" directory will
still use "/different/path" as the root of the work tree and can cause
confusion unless you know what you are doing (e.g. you are creating a
read-only snapshot of the same index to a location different from the
repository's usual working tree).

core.logAllRefUpdates::
	Enable the reflog. Updates to a ref <ref> is logged to the file
	"`$GIT_DIR/logs/<ref>`", by appending the new and old
	SHA-1, the date/time and the reason of the update, but
	only when the file exists.  If this configuration
	variable is set to `true`, missing "`$GIT_DIR/logs/<ref>`"
	file is automatically created for branch heads (i.e. under
	`refs/heads/`), remote refs (i.e. under `refs/remotes/`),
	note refs (i.e. under `refs/notes/`), and the symbolic ref `HEAD`.
	If it is set to `always`, then a missing reflog is automatically
	created for any ref under `refs/`.
+
This information can be used to determine what commit
was the tip of a branch "2 days ago".
+
This value is true by default in a repository that has
a working directory associated with it, and false by
default in a bare repository.

core.repositoryFormatVersion::
	Internal variable identifying the repository format and layout
	version.

core.sharedRepository::
	When 'group' (or 'true'), the repository is made shareable between
	several users in a group (making sure all the files and objects are
	group-writable). When 'all' (or 'world' or 'everybody'), the
	repository will be readable by all users, additionally to being
	group-shareable. When 'umask' (or 'false'), Git will use permissions
	reported by umask(2). When '0xxx', where '0xxx' is an octal number,
	files in the repository will have this mode value. '0xxx' will override
	user's umask value (whereas the other options will only override
	requested parts of the user's umask value). Examples: '0660' will make
	the repo read/write-able for the owner and group, but inaccessible to
	others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
	repository that is group-readable but not group-writable.
	See linkgit:git-init[1]. False by default.

core.warnAmbiguousRefs::
	If true, Git will warn you if the ref name you passed it is ambiguous
	and might match multiple refs in the repository. True by default.

core.compression::
	An integer -1..9, indicating a default compression level.
	-1 is the zlib default. 0 means no compression,
	and 1..9 are various speed/size tradeoffs, 9 being slowest.
	If set, this provides a default to other compression variables,
	such as `core.looseCompression` and `pack.compression`.

core.looseCompression::
	An integer -1..9, indicating the compression level for objects that
	are not in a pack file. -1 is the zlib default. 0 means no
	compression, and 1..9 are various speed/size tradeoffs, 9 being
	slowest.  If not set,  defaults to core.compression.  If that is
	not set,  defaults to 1 (best speed).

core.packedGitWindowSize::
	Number of bytes of a pack file to map into memory in a
	single mapping operation.  Larger window sizes may allow
	your system to process a smaller number of large pack files
	more quickly.  Smaller window sizes will negatively affect
	performance due to increased calls to the operating system's
	memory manager, but may improve performance when accessing
	a large number of large pack files.
+
Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
be reasonable for all users/operating systems.  You probably do
not need to adjust this value.
+
Common unit suffixes of 'k', 'm', or 'g' are supported.

core.packedGitLimit::
	Maximum number of bytes to map simultaneously into memory
	from pack files.  If Git needs to access more than this many
	bytes at once to complete an operation it will unmap existing
	regions to reclaim virtual address space within the process.
+
Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
This should be reasonable for all users/operating systems, except on
the largest projects.  You probably do not need to adjust this value.
+
Common unit suffixes of 'k', 'm', or 'g' are supported.

core.deltaBaseCacheLimit::
	Maximum number of bytes to reserve for caching base objects
	that may be referenced by multiple deltified objects.  By storing the
	entire decompressed base objects in a cache Git is able
	to avoid unpacking and decompressing frequently used base
	objects multiple times.
+
Default is 96 MiB on all platforms.  This should be reasonable
for all users/operating systems, except on the largest projects.
You probably do not need to adjust this value.
+
Common unit suffixes of 'k', 'm', or 'g' are supported.

core.bigFileThreshold::
	Files larger than this size are stored deflated, without
	attempting delta compression.  Storing large files without
	delta compression avoids excessive memory usage, at the
	slight expense of increased disk usage. Additionally files
	larger than this size are always treated as binary.
+
Default is 512 MiB on all platforms.  This should be reasonable
for most projects as source code and other text files can still
be delta compressed, but larger binary media files won't be.
+
Common unit suffixes of 'k', 'm', or 'g' are supported.

core.excludesFile::
	Specifies the pathname to the file that contains patterns to
	describe paths that are not meant to be tracked, in addition
	to '.gitignore' (per-directory) and '.git/info/exclude'.
	Defaults to `$XDG_CONFIG_HOME/git/ignore`.
	If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/ignore`
	is used instead. See linkgit:gitignore[5].

core.askPass::
	Some commands (e.g. svn and http interfaces) that interactively
	ask for a password can be told to use an external program given
	via the value of this variable. Can be overridden by the `GIT_ASKPASS`
	environment variable. If not set, fall back to the value of the
	`SSH_ASKPASS` environment variable or, failing that, a simple password
	prompt. The external program shall be given a suitable prompt as
	command-line argument and write the password on its STDOUT.

core.attributesFile::
	In addition to '.gitattributes' (per-directory) and
	'.git/info/attributes', Git looks into this file for attributes
	(see linkgit:gitattributes[5]). Path expansions are made the same
	way as for `core.excludesFile`. Its default value is
	`$XDG_CONFIG_HOME/git/attributes`. If `$XDG_CONFIG_HOME` is either not
	set or empty, `$HOME/.config/git/attributes` is used instead.

core.hooksPath::
	By default Git will look for your hooks in the
	'$GIT_DIR/hooks' directory. Set this to different path,
	e.g. '/etc/git/hooks', and Git will try to find your hooks in
	that directory, e.g. '/etc/git/hooks/pre-receive' instead of
	in '$GIT_DIR/hooks/pre-receive'.
+
The path can be either absolute or relative. A relative path is
taken as relative to the directory where the hooks are run (see
the "DESCRIPTION" section of linkgit:githooks[5]).
+
This configuration variable is useful in cases where you'd like to
centrally configure your Git hooks instead of configuring them on a
per-repository basis, or as a more flexible and centralized
alternative to having an `init.templateDir` where you've changed
default hooks.

core.editor::
	Commands such as `commit` and `tag` that lets you edit
	messages by launching an editor uses the value of this
	variable when it is set, and the environment variable
	`GIT_EDITOR` is not set.  See linkgit:git-var[1].

core.commentChar::
	Commands such as `commit` and `tag` that lets you edit
	messages consider a line that begins with this character
	commented, and removes them after the editor returns
	(default '#').
+
If set to "auto", `git-commit` would select a character that is not
the beginning character of any line in existing commit messages.

core.packedRefsTimeout::
	The length of time, in milliseconds, to retry when trying to
	lock the `packed-refs` file. Value 0 means not to retry at
	all; -1 means to try indefinitely. Default is 1000 (i.e.,
	retry for 1 second).

sequence.editor::
	Text editor used by `git rebase -i` for editing the rebase instruction file.
	The value is meant to be interpreted by the shell when it is used.
	It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
	When not configured the default commit message editor is used instead.

core.pager::
	Text viewer for use by Git commands (e.g., 'less').  The value
	is meant to be interpreted by the shell.  The order of preference
	is the `$GIT_PAGER` environment variable, then `core.pager`
	configuration, then `$PAGER`, and then the default chosen at
	compile time (usually 'less').
+
When the `LESS` environment variable is unset, Git sets it to `FRX`
(if `LESS` environment variable is set, Git does not change it at
all).  If you want to selectively override Git's default setting
for `LESS`, you can set `core.pager` to e.g. `less -S`.  This will
be passed to the shell by Git, which will translate the final
command to `LESS=FRX less -S`. The environment does not set the
`S` option but the command line does, instructing less to truncate
long lines. Similarly, setting `core.pager` to `less -+F` will
deactivate the `F` option specified by the environment from the
command-line, deactivating the "quit if one screen" behavior of
`less`.  One can specifically activate some flags for particular
commands: for example, setting `pager.blame` to `less -S` enables
line truncation only for `git blame`.
+
Likewise, when the `LV` environment variable is unset, Git sets it
to `-c`.  You can override this setting by exporting `LV` with
another value or setting `core.pager` to `lv +c`.

core.whitespace::
	A comma separated list of common whitespace problems to
	notice.  'git diff' will use `color.diff.whitespace` to
	highlight them, and 'git apply --whitespace=error' will
	consider them as errors.  You can prefix `-` to disable
	any of them (e.g. `-trailing-space`):
+
* `blank-at-eol` treats trailing whitespaces at the end of the line
  as an error (enabled by default).
* `space-before-tab` treats a space character that appears immediately
  before a tab character in the initial indent part of the line as an
  error (enabled by default).
* `indent-with-non-tab` treats a line that is indented with space
  characters instead of the equivalent tabs as an error (not enabled by
  default).
* `tab-in-indent` treats a tab character in the initial indent part of
  the line as an error (not enabled by default).
* `blank-at-eof` treats blank lines added at the end of file as an error
  (enabled by default).
* `trailing-space` is a short-hand to cover both `blank-at-eol` and
  `blank-at-eof`.
* `cr-at-eol` treats a carriage-return at the end of line as
  part of the line terminator, i.e. with it, `trailing-space`
  does not trigger if the character before such a carriage-return
  is not a whitespace (not enabled by default).
* `tabwidth=<n>` tells how many character positions a tab occupies; this
  is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent`
  errors. The default tab width is 8. Allowed values are 1 to 63.

core.fsyncObjectFiles::
	This boolean will enable 'fsync()' when writing object files.
+
This is a total waste of time and effort on a filesystem that orders
data writes properly, but can be useful for filesystems that do not use
journalling (traditional UNIX filesystems) or that only journal metadata
and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").

core.preloadIndex::
	Enable parallel index preload for operations like 'git diff'
+
This can speed up operations like 'git diff' and 'git status' especially
on filesystems like NFS that have weak caching semantics and thus
relatively high IO latencies.  When enabled, Git will do the
index comparison to the filesystem data in parallel, allowing
overlapping IO's.  Defaults to true.

core.createObject::
	You can set this to 'link', in which case a hardlink followed by
	a delete of the source are used to make sure that object creation
	will not overwrite existing objects.
+
On some file system/operating system combinations, this is unreliable.
Set this config setting to 'rename' there; However, This will remove the
check that makes sure that existing object files will not get overwritten.

core.notesRef::
	When showing commit messages, also show notes which are stored in
	the given ref.  The ref must be fully qualified.  If the given
	ref does not exist, it is not an error but means that no
	notes should be printed.
+
This setting defaults to "refs/notes/commits", and it can be overridden by
the `GIT_NOTES_REF` environment variable.  See linkgit:git-notes[1].

core.sparseCheckout::
	Enable "sparse checkout" feature. See section "Sparse checkout" in
	linkgit:git-read-tree[1] for more information.

core.abbrev::
	Set the length object names are abbreviated to.  If
	unspecified or set to "auto", an appropriate value is
	computed based on the approximate number of packed objects
	in your repository, which hopefully is enough for
	abbreviated object names to stay unique for some time.

add.ignoreErrors::
add.ignore-errors (deprecated)::
	Tells 'git add' to continue adding files when some files cannot be
	added due to indexing errors. Equivalent to the `--ignore-errors`
	option of linkgit:git-add[1].  `add.ignore-errors` is deprecated,
	as it does not follow the usual naming convention for configuration
	variables.

alias.*::
	Command aliases for the linkgit:git[1] command wrapper - e.g.
	after defining "alias.last = cat-file commit HEAD", the invocation
	"git last" is equivalent to "git cat-file commit HEAD". To avoid
	confusion and troubles with script usage, aliases that
	hide existing Git commands are ignored. Arguments are split by
	spaces, the usual shell quoting and escaping is supported.
	A quote pair or a backslash can be used to quote them.
+
If the alias expansion is prefixed with an exclamation point,
it will be treated as a shell command.  For example, defining
"alias.new = !gitk --all --not ORIG_HEAD", the invocation
"git new" is equivalent to running the shell command
"gitk --all --not ORIG_HEAD".  Note that shell commands will be
executed from the top-level directory of a repository, which may
not necessarily be the current directory.
`GIT_PREFIX` is set as returned by running 'git rev-parse --show-prefix'
from the original current directory. See linkgit:git-rev-parse[1].

am.keepcr::
	If true, git-am will call git-mailsplit for patches in mbox format
	with parameter `--keep-cr`. In this case git-mailsplit will
	not remove `\r` from lines ending with `\r\n`. Can be overridden
	by giving `--no-keep-cr` from the command line.
	See linkgit:git-am[1], linkgit:git-mailsplit[1].

am.threeWay::
	By default, `git am` will fail if the patch does not apply cleanly. When
	set to true, this setting tells `git am` to fall back on 3-way merge if
	the patch records the identity of blobs it is supposed to apply to and
	we have those blobs available locally (equivalent to giving the `--3way`
	option from the command line). Defaults to `false`.
	See linkgit:git-am[1].

apply.ignoreWhitespace::
	When set to 'change', tells 'git apply' to ignore changes in
	whitespace, in the same way as the `--ignore-space-change`
	option.
	When set to one of: no, none, never, false tells 'git apply' to
	respect all whitespace differences.
	See linkgit:git-apply[1].

apply.whitespace::
	Tells 'git apply' how to handle whitespaces, in the same way
	as the `--whitespace` option. See linkgit:git-apply[1].

branch.autoSetupMerge::
	Tells 'git branch' and 'git checkout' to set up new branches
	so that linkgit:git-pull[1] will appropriately merge from the
	starting point branch. Note that even if this option is not set,
	this behavior can be chosen per-branch using the `--track`
	and `--no-track` options. The valid settings are: `false` -- no
	automatic setup is done; `true` -- automatic setup is done when the
	starting point is a remote-tracking branch; `always` --
	automatic setup is done when the starting point is either a
	local branch or remote-tracking
	branch. This option defaults to true.

branch.autoSetupRebase::
	When a new branch is created with 'git branch' or 'git checkout'
	that tracks another branch, this variable tells Git to set
	up pull to rebase instead of merge (see "branch.<name>.rebase").
	When `never`, rebase is never automatically set to true.
	When `local`, rebase is set to true for tracked branches of
	other local branches.
	When `remote`, rebase is set to true for tracked branches of
	remote-tracking branches.
	When `always`, rebase will be set to true for all tracking
	branches.
	See "branch.autoSetupMerge" for details on how to set up a
	branch to track another branch.
	This option defaults to never.

branch.<name>.remote::
	When on branch <name>, it tells 'git fetch' and 'git push'
	which remote to fetch from/push to.  The remote to push to
	may be overridden with `remote.pushDefault` (for all branches).
	The remote to push to, for the current branch, may be further
	overridden by `branch.<name>.pushRemote`.  If no remote is
	configured, or if you are not on any branch, it defaults to
	`origin` for fetching and `remote.pushDefault` for pushing.
	Additionally, `.` (a period) is the current local repository
	(a dot-repository), see `branch.<name>.merge`'s final note below.

branch.<name>.pushRemote::
	When on branch <name>, it overrides `branch.<name>.remote` for
	pushing.  It also overrides `remote.pushDefault` for pushing
	from branch <name>.  When you pull from one place (e.g. your
	upstream) and push to another place (e.g. your own publishing
	repository), you would want to set `remote.pushDefault` to
	specify the remote to push to for all branches, and use this
	option to override it for a specific branch.

branch.<name>.merge::
	Defines, together with branch.<name>.remote, the upstream branch
	for the given branch. It tells 'git fetch'/'git pull'/'git rebase' which
	branch to merge and can also affect 'git push' (see push.default).
	When in branch <name>, it tells 'git fetch' the default
	refspec to be marked for merging in FETCH_HEAD. The value is
	handled like the remote part of a refspec, and must match a
	ref which is fetched from the remote given by
	"branch.<name>.remote".
	The merge information is used by 'git pull' (which at first calls
	'git fetch') to lookup the default branch for merging. Without
	this option, 'git pull' defaults to merge the first refspec fetched.
	Specify multiple values to get an octopus merge.
	If you wish to setup 'git pull' so that it merges into <name> from
	another branch in the local repository, you can point
	branch.<name>.merge to the desired branch, and use the relative path
	setting `.` (a period) for branch.<name>.remote.

branch.<name>.mergeOptions::
	Sets default options for merging into branch <name>. The syntax and
	supported options are the same as those of linkgit:git-merge[1], but
	option values containing whitespace characters are currently not
	supported.

branch.<name>.rebase::
	When true, rebase the branch <name> on top of the fetched branch,
	instead of merging the default branch from the default remote when
	"git pull" is run. See "pull.rebase" for doing this in a non
	branch-specific manner.
+
When preserve, also pass `--preserve-merges` along to 'git rebase'
so that locally committed merge commits will not be flattened
by running 'git pull'.
