[git/git.git] / Documentation / config.txt
2 ------------------
4 The git configuration file contains a number of variables that affect
5 the git command's behavior. `.git/config` file for each repository
6 is used to store the information for that repository, and
7 `$HOME/.gitconfig` is used to store per user information to give
8 fallback values for `.git/config` file. The file `/etc/gitconfig`
9 can be used to store system-wide defaults.
11 They can be used by both the git plumbing
12 and the porcelains. The variables are divided into sections, where
13 in the fully qualified variable name the variable itself is the last
14 dot-separated segment and the section name is everything before the last
15 dot. The variable names are case-insensitive and only alphanumeric
16 characters are allowed. Some variables may appear multiple times.
18 Syntax
19 ~~~~~~
21 The syntax is fairly flexible and permissive; whitespaces are mostly
22 ignored. The '#' and ';' characters begin comments to the end of line,
23 blank lines are ignored.
25 The file consists of sections and variables. A section begins with
26 the name of the section in square brackets and continues until the next
27 section begins. Section names are not case sensitive. Only alphanumeric
28 characters, '`-`' and '`.`' are allowed in section names. Each variable
29 must belong to some section, which means that there must be section
30 header before first setting of a variable.
32 Sections can be further divided into subsections. To begin a subsection
33 put its name in double quotes, separated by space from the section name,
34 in the section header, like in example below:
36 --------
37 [section "subsection"]
39 --------
41 Subsection names can contain any characters except newline (doublequote
42 '`"`' and backslash have to be escaped as '`\"`' and '`\\`',
43 respectively) and are case sensitive. Section header cannot span multiple
44 lines. Variables may belong directly to a section or to a given subsection.
45 You can have `[section]` if you have `[section "subsection"]`, but you
46 don't need to.
48 There is also (case insensitive) alternative `[section.subsection]` syntax.
49 In this syntax subsection names follow the same restrictions as for section
50 name.
52 All the other lines are recognized as setting variables, in the form
53 'name = value'. If there is no equal sign on the line, the entire line
54 is taken as 'name' and the variable is recognized as boolean "true".
55 The variable names are case-insensitive and only alphanumeric
56 characters and '`-`' are allowed. There can be more than one value
57 for a given variable; we say then that variable is multivalued.
59 Leading and trailing whitespace in a variable value is discarded.
60 Internal whitespace within a variable value is retained verbatim.
62 The values following the equals sign in variable assign are all either
63 a string, an integer, or a boolean. Boolean values may be given as yes/no,
64 0/1 or true/false. Case is not significant in boolean values, when
65 converting value to the canonical form using '--bool' type specifier;
66 'git-config' will ensure that the output is "true" or "false".
68 String values may be entirely or partially enclosed in double quotes.
69 You need to enclose variable value in double quotes if you want to
70 preserve leading or trailing whitespace, or if variable value contains
71 beginning of comment characters (if it contains '#' or ';').
72 Double quote '`"`' and backslash '`\`' characters in variable value must
73 be escaped: use '`\"`' for '`"`' and '`\\`' for '`\`'.
75 The following escape sequences (beside '`\"`' and '`\\`') are recognized:
76 '`\n`' for newline character (NL), '`\t`' for horizontal tabulation (HT, TAB)
77 and '`\b`' for backspace (BS). No other char escape sequence, nor octal
78 char sequences are valid.
80 Variable value ending in a '`\`' is continued on the next line in the
81 customary UNIX fashion.
83 Some variables may require special value format.

107 Variables
108 ~~~~~~~~~
110 Note that this list is non-comprehensive and not necessarily complete.
111 For command-specific variables, you will find a more detailed description
112 in the appropriate manual page. You will find a description of non-core
113 porcelain configuration variables in the respective porcelain documentation.
115 core.fileMode::
116 If false, the executable bit differences between the index and
117 the working copy are ignored; useful on broken filesystems like FAT.
118 See linkgit:git-update-index[1]. True by default.
120 core.trustctime::
121 If false, the ctime differences between the index and the
122 working copy are ignored; useful when the inode change time
123 is regularly modified by something outside Git (file system
124 crawlers and some backup systems).
125 See linkgit:git-update-index[1]. True by default.
127 core.quotepath::
128 The commands that output paths (e.g. 'ls-files',
129 'diff'), when not given the `-z` option, will quote
130 "unusual" characters in the pathname by enclosing the
131 pathname in a double-quote pair and with backslashes the
132 same way strings in C source code are quoted. If this
133 variable is set to false, the bytes higher than 0x80 are
134 not quoted but output as verbatim. Note that double
135 quote, backslash and control characters are always
136 quoted without `-z` regardless of the setting of this
137 variable.
139 core.autocrlf::
140 If true, makes git convert `CRLF` at the end of lines in text files to
141 `LF` when reading from the filesystem, and convert in reverse when
142 writing to the filesystem. The variable can be set to
143 'input', in which case the conversion happens only while
144 reading from the filesystem but files are written out with
145 `LF` at the end of lines. Currently, which paths to consider
146 "text" (i.e. be subjected to the autocrlf mechanism) is
147 decided purely based on the contents.
149 core.safecrlf::
150 If true, makes git check if converting `CRLF` as controlled by
151 `core.autocrlf` is reversible. Git will verify if a command
152 modifies a file in the work tree either directly or indirectly.
153 For example, committing a file followed by checking out the
154 same file should yield the original file in the work tree. If
155 this is not the case for the current setting of
156 `core.autocrlf`, git will reject the file. The variable can
157 be set to "warn", in which case git will only warn about an
158 irreversible conversion but continue the operation.
159 +
160 CRLF conversion bears a slight chance of corrupting data.
161 autocrlf=true will convert CRLF to LF during commit and LF to
162 CRLF during checkout. A file that contains a mixture of LF and
163 CRLF before the commit cannot be recreated by git. For text
164 files this is the right thing to do: it corrects line endings
165 such that we have only LF line endings in the repository.
166 But for binary files that are accidentally classified as text the
167 conversion can corrupt data.
168 +
169 If you recognize such corruption early you can easily fix it by
170 setting the conversion type explicitly in .gitattributes. Right
171 after committing you still have the original file in your work
172 tree and this file is not yet corrupted. You can explicitly tell
173 git that this file is binary and git will handle the file
174 appropriately.
175 +
176 Unfortunately, the desired effect of cleaning up text files with
177 mixed line endings and the undesired effect of corrupting binary
178 files cannot be distinguished. In both cases CRLFs are removed
179 in an irreversible way. For text files this is the right thing
180 to do because CRLFs are line endings, while for binary files
181 converting CRLFs corrupts data.
182 +
183 Note, this safety check does not mean that a checkout will generate a
184 file identical to the original file for a different setting of
185 `core.autocrlf`, but only for the current one. For example, a text
186 file with `LF` would be accepted with `core.autocrlf=input` and could
187 later be checked out with `core.autocrlf=true`, in which case the
188 resulting file would contain `CRLF`, although the original file
189 contained `LF`. However, in both work trees the line endings would be
190 consistent, that is either all `LF` or all `CRLF`, but never mixed. A
191 file with mixed line endings would be reported by the `core.safecrlf`
192 mechanism.
194 core.symlinks::
195 If false, symbolic links are checked out as small plain files that
196 contain the link text. linkgit:git-update-index[1] and
197 linkgit:git-add[1] will not change the recorded type to regular
198 file. Useful on filesystems like FAT that do not support
199 symbolic links. True by default.
201 core.gitProxy::
202 A "proxy command" to execute (as 'command host port') instead
203 of establishing direct connection to the remote server when
204 using the git protocol for fetching. If the variable value is
205 in the "COMMAND for DOMAIN" format, the command is applied only
206 on hostnames ending with the specified domain string. This variable
207 may be set multiple times and is matched in the given order;
208 the first match wins.
209 +
210 Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
211 (which always applies universally, without the special "for"
212 handling).
214 core.ignoreStat::
215 If true, commands which modify both the working tree and the index
216 will mark the updated paths with the "assume unchanged" bit in the
217 index. These marked files are then assumed to stay unchanged in the
218 working copy, until you mark them otherwise manually - Git will not
219 detect the file changes by lstat() calls. This is useful on systems
220 where those are very slow, such as Microsoft Windows.
221 See linkgit:git-update-index[1].
222 False by default.
224 core.preferSymlinkRefs::
225 Instead of the default "symref" format for HEAD
226 and other symbolic reference files, use symbolic links.
227 This is sometimes needed to work with old scripts that
228 expect HEAD to be a symbolic link.
230 core.bare::
231 If true this repository is assumed to be 'bare' and has no
232 working directory associated with it. If this is the case a
233 number of commands that require a working directory will be
234 disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
235 +
236 This setting is automatically guessed by linkgit:git-clone[1] or
237 linkgit:git-init[1] when the repository was created. By default a
238 repository that ends in "/.git" is assumed to be not bare (bare =
239 false), while all other repositories are assumed to be bare (bare
240 = true).
242 core.worktree::
243 Set the path to the working tree. The value will not be
244 used in combination with repositories found automatically in
245 a .git directory (i.e. $GIT_DIR is not set).
246 This can be overridden by the GIT_WORK_TREE environment
247 variable and the '--work-tree' command line option. It can be
248 a absolute path or relative path to the directory specified by
249 --git-dir or GIT_DIR.
250 Note: If --git-dir or GIT_DIR are specified but none of
251 --work-tree, GIT_WORK_TREE and core.worktree is specified,
252 the current working directory is regarded as the top directory
253 of your working tree.
255 core.logAllRefUpdates::
256 Enable the reflog. Updates to a ref <ref> is logged to the file
257 "$GIT_DIR/logs/<ref>", by appending the new and old
258 SHA1, the date/time and the reason of the update, but
259 only when the file exists. If this configuration
260 variable is set to true, missing "$GIT_DIR/logs/<ref>"
261 file is automatically created for branch heads.
262 +
263 This information can be used to determine what commit
264 was the tip of a branch "2 days ago".
265 +
266 This value is true by default in a repository that has
267 a working directory associated with it, and false by
268 default in a bare repository.
270 core.repositoryFormatVersion::
271 Internal variable identifying the repository format and layout
272 version.
274 core.sharedRepository::
275 When 'group' (or 'true'), the repository is made shareable between
276 several users in a group (making sure all the files and objects are
277 group-writable). When 'all' (or 'world' or 'everybody'), the
278 repository will be readable by all users, additionally to being
279 group-shareable. When 'umask' (or 'false'), git will use permissions
280 reported by umask(2). When '0xxx', where '0xxx' is an octal number,
281 files in the repository will have this mode value. '0xxx' will override
282 user's umask value, and thus, users with a safe umask (0077) can use
283 this option. Examples: '0660' is equivalent to 'group'. '0640' is a
284 repository that is group-readable but not group-writable.
285 See linkgit:git-init[1]. False by default.
287 core.warnAmbiguousRefs::
288 If true, git will warn you if the ref name you passed it is ambiguous
289 and might match multiple refs in the .git/refs/ tree. True by default.
291 core.compression::
292 An integer -1..9, indicating a default compression level.
293 -1 is the zlib default. 0 means no compression,
294 and 1..9 are various speed/size tradeoffs, 9 being slowest.
295 If set, this provides a default to other compression variables,
296 such as 'core.loosecompression' and 'pack.compression'.
298 core.loosecompression::
299 An integer -1..9, indicating the compression level for objects that
300 are not in a pack file. -1 is the zlib default. 0 means no
301 compression, and 1..9 are various speed/size tradeoffs, 9 being
302 slowest. If not set, defaults to core.compression. If that is
303 not set, defaults to 1 (best speed).
305 core.packedGitWindowSize::
306 Number of bytes of a pack file to map into memory in a
307 single mapping operation. Larger window sizes may allow
308 your system to process a smaller number of large pack files
309 more quickly. Smaller window sizes will negatively affect
310 performance due to increased calls to the operating system's
311 memory manager, but may improve performance when accessing
312 a large number of large pack files.
313 +
314 Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
315 MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should
316 be reasonable for all users/operating systems. You probably do
317 not need to adjust this value.
318 +
319 Common unit suffixes of 'k', 'm', or 'g' are supported.
321 core.packedGitLimit::
322 Maximum number of bytes to map simultaneously into memory
323 from pack files. If Git needs to access more than this many
324 bytes at once to complete an operation it will unmap existing
325 regions to reclaim virtual address space within the process.
326 +
327 Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
328 This should be reasonable for all users/operating systems, except on
329 the largest projects. You probably do not need to adjust this value.
330 +
331 Common unit suffixes of 'k', 'm', or 'g' are supported.
333 core.deltaBaseCacheLimit::
334 Maximum number of bytes to reserve for caching base objects
335 that multiple deltafied objects reference. By storing the
336 entire decompressed base objects in a cache Git is able
337 to avoid unpacking and decompressing frequently used base
338 objects multiple times.
339 +
340 Default is 16 MiB on all platforms. This should be reasonable
341 for all users/operating systems, except on the largest projects.
342 You probably do not need to adjust this value.
343 +
344 Common unit suffixes of 'k', 'm', or 'g' are supported.
346 core.excludesfile::
347 In addition to '.gitignore' (per-directory) and
348 '.git/info/exclude', git looks into this file for patterns
349 of files which are not meant to be tracked. See
350 linkgit:gitignore[5].
352 core.editor::
353 Commands such as `commit` and `tag` that lets you edit
354 messages by launching an editor uses the value of this
355 variable when it is set, and the environment variable
356 `GIT_EDITOR` is not set. The order of preference is
357 `GIT_EDITOR` environment, `core.editor`, `VISUAL` and
358 `EDITOR` environment variables and then finally `vi`.
360 core.pager::
361 The command that git will use to paginate output. Can be overridden
362 with the `GIT_PAGER` environment variable.
364 core.whitespace::
365 A comma separated list of common whitespace problems to
366 notice. 'git-diff' will use `color.diff.whitespace` to
367 highlight them, and 'git-apply --whitespace=error' will
368 consider them as errors. You can prefix `-` to disable
369 any of them (e.g. `-trailing-space`):
370 +
371 * `trailing-space` treats trailing whitespaces at the end of the line
372 as an error (enabled by default).
373 * `space-before-tab` treats a space character that appears immediately
374 before a tab character in the initial indent part of the line as an
375 error (enabled by default).
376 * `indent-with-non-tab` treats a line that is indented with 8 or more
377 space characters as an error (not enabled by default).
378 * `cr-at-eol` treats a carriage-return at the end of line as
379 part of the line terminator, i.e. with it, `trailing-space`
380 does not trigger if the character before such a carriage-return
381 is not a whitespace (not enabled by default).
383 core.fsyncobjectfiles::
384 This boolean will enable 'fsync()' when writing object files.
385 +
386 This is a total waste of time and effort on a filesystem that orders
387 data writes properly, but can be useful for filesystems that do not use
388 journalling (traditional UNIX filesystems) or that only journal metadata
389 and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
391 alias.*::
392 Command aliases for the linkgit:git[1] command wrapper - e.g.
393 after defining "alias.last = cat-file commit HEAD", the invocation
394 "git last" is equivalent to "git cat-file commit HEAD". To avoid
395 confusion and troubles with script usage, aliases that
396 hide existing git commands are ignored. Arguments are split by
397 spaces, the usual shell quoting and escaping is supported.
398 quote pair and a backslash can be used to quote them.
399 +
400 If the alias expansion is prefixed with an exclamation point,
401 it will be treated as a shell command. For example, defining
402 " = !gitk --all --not ORIG_HEAD", the invocation
403 "git new" is equivalent to running the shell command
404 "gitk --all --not ORIG_HEAD".
406 apply.whitespace::
407 Tells 'git-apply' how to handle whitespaces, in the same way
408 as the '--whitespace' option. See linkgit:git-apply[1].
410 branch.autosetupmerge::
411 Tells 'git-branch' and 'git-checkout' to setup new branches
412 so that linkgit:git-pull[1] will appropriately merge from the
413 starting point branch. Note that even if this option is not set,
414 this behavior can be chosen per-branch using the `--track`
415 and `--no-track` options. The valid settings are: `false` -- no
416 automatic setup is done; `true` -- automatic setup is done when the
417 starting point is a remote branch; `always` -- automatic setup is
418 done when the starting point is either a local branch or remote
419 branch. This option defaults to true.
421 branch.autosetuprebase::
422 When a new branch is created with 'git-branch' or 'git-checkout'
423 that tracks another branch, this variable tells git to set
424 up pull to rebase instead of merge (see "branch.<name>.rebase").
425 When `never`, rebase is never automatically set to true.
426 When `local`, rebase is set to true for tracked branches of
427 other local branches.
428 When `remote`, rebase is set to true for tracked branches of
429 remote branches.
430 When `always`, rebase will be set to true for all tracking
431 branches.
432 See "branch.autosetupmerge" for details on how to set up a
433 branch to track another branch.
434 This option defaults to never.
436 branch.<name>.remote::
437 When in branch <name>, it tells 'git-fetch' which remote to fetch.
438 If this option is not given, 'git-fetch' defaults to remote "origin".
440 branch.<name>.merge::
441 When in branch <name>, it tells 'git-fetch' the default
442 refspec to be marked for merging in FETCH_HEAD. The value is
443 handled like the remote part of a refspec, and must match a
444 ref which is fetched from the remote given by
445 "branch.<name>.remote".
446 The merge information is used by 'git-pull' (which at first calls
447 'git-fetch') to lookup the default branch for merging. Without
448 this option, 'git-pull' defaults to merge the first refspec fetched.
449 Specify multiple values to get an octopus merge.
450 If you wish to setup 'git-pull' so that it merges into <name> from
451 another branch in the local repository, you can point
452 branch.<name>.merge to the desired branch, and use the special setting
453 `.` (a period) for branch.<name>.remote.
455 branch.<name>.mergeoptions::
456 Sets default options for merging into branch <name>. The syntax and
457 supported options are equal to that of linkgit:git-merge[1], but
458 option values containing whitespace characters are currently not
459 supported.
461 branch.<name>.rebase::
462 When true, rebase the branch <name> on top of the fetched branch,
463 instead of merging the default branch from the default remote when
464 "git pull" is run.
465 *NOTE*: this is a possibly dangerous operation; do *not* use
466 it unless you understand the implications (see linkgit:git-rebase[1]
467 for details).
469 browser.<tool>.cmd::
470 Specify the command to invoke the specified browser. The
471 specified command is evaluated in shell with the URLs passed
472 as arguments. (See linkgit:git-web--browse[1].)
474 browser.<tool>.path::
475 Override the path for the given tool that may be used to
476 browse HTML help (see '-w' option in linkgit:git-help[1]) or a
477 working repository in gitweb (see linkgit:git-instaweb[1]).
479 clean.requireForce::
480 A boolean to make git-clean do nothing unless given -f
481 or -n. Defaults to true.
483 color.branch::
484 A boolean to enable/disable color in the output of
485 linkgit:git-branch[1]. May be set to `always`,
486 `false` (or `never`) or `auto` (or `true`), in which case colors are used
487 only when the output is to a terminal. Defaults to false.
489 color.branch.<slot>::
490 Use customized color for branch coloration. `<slot>` is one of
491 `current` (the current branch), `local` (a local branch),
492 `remote` (a tracking branch in refs/remotes/), `plain` (other
493 refs).
494 +
495 The value for these configuration variables is a list of colors (at most
496 two) and attributes (at most one), separated by spaces. The colors
497 accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
498 `magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
499 `blink` and `reverse`. The first color given is the foreground; the
500 second is the background. The position of the attribute, if any,
501 doesn't matter.
503 color.diff::
504 When set to `always`, always use colors in patch.
505 When false (or `never`), never. When set to `true` or `auto`, use
506 colors only when the output is to the terminal. Defaults to false.
508 color.diff.<slot>::
509 Use customized color for diff colorization. `<slot>` specifies
510 which part of the patch to use the specified color, and is one
511 of `plain` (context text), `meta` (metainformation), `frag`
512 (hunk header), `old` (removed lines), `new` (added lines),
513 `commit` (commit headers), or `whitespace` (highlighting
514 whitespace errors). The values of these variables may be specified as
515 in color.branch.<slot>.
517 color.interactive::
518 When set to `always`, always use colors for interactive prompts
519 and displays (such as those used by "git-add --interactive").
520 When false (or `never`), never. When set to `true` or `auto`, use
521 colors only when the output is to the terminal. Defaults to false.
523 color.interactive.<slot>::
524 Use customized color for 'git-add --interactive'
525 output. `<slot>` may be `prompt`, `header`, or `help`, for
526 three distinct types of normal output from interactive
527 programs. The values of these variables may be specified as
528 in color.branch.<slot>.
530 color.pager::
531 A boolean to enable/disable colored output when the pager is in
532 use (default is true).
534 color.status::
535 A boolean to enable/disable color in the output of
536 linkgit:git-status[1]. May be set to `always`,
537 `false` (or `never`) or `auto` (or `true`), in which case colors are used
538 only when the output is to a terminal. Defaults to false.
540 color.status.<slot>::
541 Use customized color for status colorization. `<slot>` is
542 one of `header` (the header text of the status message),
543 `added` or `updated` (files which are added but not committed),
544 `changed` (files which are changed but not added in the index),
545 `untracked` (files which are not tracked by git), or
546 `nobranch` (the color the 'no branch' warning is shown in, defaulting
547 to red). The values of these variables may be specified as in
548 color.branch.<slot>.
550 commit.template::
551 Specify a file to use as the template for new commit messages.
553 color.ui::
554 When set to `always`, always use colors in all git commands which
555 are capable of colored output. When false (or `never`), never. When
556 set to `true` or `auto`, use colors only when the output is to the
557 terminal. When more specific variables of color.* are set, they always
558 take precedence over this setting. Defaults to false.
560 diff.autorefreshindex::
561 When using 'git-diff' to compare with work tree
562 files, do not consider stat-only change as changed.
563 Instead, silently run `git update-index --refresh` to
564 update the cached stat information for paths whose
565 contents in the work tree match the contents in the
566 index. This option defaults to true. Note that this
567 affects only 'git-diff' Porcelain, and not lower level
568 'diff' commands, such as 'git-diff-files'.
570 diff.suppress-blank-empty::
571 A boolean to inhibit the standard behavior of printing a space
572 before each empty output line. Defaults to false.
574 diff.external::
575 If this config variable is set, diff generation is not
576 performed using the internal diff machinery, but using the
577 given command. Can be overridden with the `GIT_EXTERNAL_DIFF'
578 environment variable. The command is called with parameters
579 as described under "git Diffs" in linkgit:git[1]. Note: if
580 you want to use an external diff program only on a subset of
581 your files, you might want to use linkgit:gitattributes[5] instead.
583 diff.renameLimit::
584 The number of files to consider when performing the copy/rename
585 detection; equivalent to the 'git-diff' option '-l'.
587 diff.renames::
588 Tells git to detect renames. If set to any boolean value, it
589 will enable basic rename detection. If set to "copies" or
590 "copy", it will detect copies, as well.
592 fetch.unpackLimit::
593 If the number of objects fetched over the git native
594 transfer is below this
595 limit, then the objects will be unpacked into loose object
596 files. However if the number of received objects equals or
597 exceeds this limit then the received pack will be stored as
598 a pack, after adding any missing delta bases. Storing the
599 pack from a push can make the push operation complete faster,
600 especially on slow filesystems. If not set, the value of
601 `transfer.unpackLimit` is used instead.
603 format.numbered::
604 A boolean which can enable sequence numbers in patch subjects.
605 Setting this option to "auto" will enable it only if there is
606 more than one patch. See --numbered option in
607 linkgit:git-format-patch[1].
609 format.headers::
610 Additional email headers to include in a patch to be submitted
611 by mail. See linkgit:git-format-patch[1].
613 format.suffix::
614 The default for format-patch is to output files with the suffix
615 `.patch`. Use this variable to change that suffix (make sure to
616 include the dot if you want it).
618 format.pretty::
619 The default pretty format for log/show/whatchanged command,
620 See linkgit:git-log[1], linkgit:git-show[1],
621 linkgit:git-whatchanged[1].
623 gc.aggressiveWindow::
624 The window size parameter used in the delta compression
625 algorithm used by 'git-gc --aggressive'. This defaults
626 to 10.
629 When there are approximately more than this many loose
630 objects in the repository, `git gc --auto` will pack them.
631 Some Porcelain commands use this command to perform a
632 light-weight garbage collection from time to time. The
633 default value is 6700. Setting this to 0 disables it.
635 gc.autopacklimit::
636 When there are more than this many packs that are not
637 marked with `*.keep` file in the repository, `git gc
638 --auto` consolidates them into one larger pack. The
639 default value is 50. Setting this to 0 disables it.
641 gc.packrefs::
642 'git-gc' does not run `git pack-refs` in a bare repository by
643 default so that older dumb-transport clients can still fetch
644 from the repository. Setting this to `true` lets 'git-gc'
645 to run `git pack-refs`. Setting this to `false` tells
646 'git-gc' never to run `git pack-refs`. The default setting is
647 `notbare`. Enable it only when you know you do not have to
648 support such clients. The default setting will change to `true`
649 at some stage, and setting this to `false` will continue to
650 prevent `git pack-refs` from being run from 'git-gc'.
652 gc.pruneexpire::
653 When 'git-gc' is run, it will call 'prune --expire 2.weeks.ago'.
654 Override the grace period with this config variable.
656 gc.reflogexpire::
657 'git-reflog expire' removes reflog entries older than
658 this time; defaults to 90 days.
660 gc.reflogexpireunreachable::
661 'git-reflog expire' removes reflog entries older than
662 this time and are not reachable from the current tip;
663 defaults to 30 days.
665 gc.rerereresolved::
666 Records of conflicted merge you resolved earlier are
667 kept for this many days when 'git-rerere gc' is run.
668 The default is 60 days. See linkgit:git-rerere[1].
670 gc.rerereunresolved::
671 Records of conflicted merge you have not resolved are
672 kept for this many days when 'git-rerere gc' is run.
673 The default is 15 days. See linkgit:git-rerere[1].
675 rerere.autoupdate::
676 When set to true, `git-rerere` updates the index with the
677 resulting contents after it cleanly resolves conflicts using
678 previously recorded resolution. Defaults to false.
680 rerere.enabled::
681 Activate recording of resolved conflicts, so that identical
682 conflict hunks can be resolved automatically, should they
683 be encountered again. linkgit:git-rerere[1] command is by
684 default enabled if you create `rr-cache` directory under
685 `$GIT_DIR`, but can be disabled by setting this option to false.
687 gitcvs.enabled::
688 Whether the CVS server interface is enabled for this repository.
689 See linkgit:git-cvsserver[1].
691 gitcvs.logfile::
692 Path to a log file where the CVS server interface well... logs
693 various stuff. See linkgit:git-cvsserver[1].
695 gitcvs.usecrlfattr
696 If true, the server will look up the `crlf` attribute for
697 files to determine the '-k' modes to use. If `crlf` is set,
698 the '-k' mode will be left blank, so cvs clients will
699 treat it as text. If `crlf` is explicitly unset, the file
700 will be set with '-kb' mode, which suppresses any newline munging
701 the client might otherwise do. If `crlf` is not specified,
702 then 'gitcvs.allbinary' is used. See linkgit:gitattributes[5].
704 gitcvs.allbinary::
705 This is used if 'gitcvs.usecrlfattr' does not resolve
706 the correct '-kb' mode to use. If true, all
707 unresolved files are sent to the client in
708 mode '-kb'. This causes the client to treat them
709 as binary files, which suppresses any newline munging it
710 otherwise might do. Alternatively, if it is set to "guess",
711 then the contents of the file are examined to decide if
712 it is binary, similar to 'core.autocrlf'.
714 gitcvs.dbname::
715 Database used by git-cvsserver to cache revision information
716 derived from the git repository. The exact meaning depends on the
717 used database driver, for SQLite (which is the default driver) this
718 is a filename. Supports variable substitution (see
719 linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
720 Default: '%Ggitcvs.%m.sqlite'
722 gitcvs.dbdriver::
723 Used Perl DBI driver. You can specify any available driver
724 for this here, but it might not work. git-cvsserver is tested
725 with 'DBD::SQLite', reported to work with 'DBD::Pg', and
726 reported *not* to work with 'DBD::mysql'. Experimental feature.
727 May not contain double colons (`:`). Default: 'SQLite'.
728 See linkgit:git-cvsserver[1].
730 gitcvs.dbuser, gitcvs.dbpass::
731 Database user and password. Only useful if setting 'gitcvs.dbdriver',
732 since SQLite has no concept of database users and/or passwords.
733 'gitcvs.dbuser' supports variable substitution (see
734 linkgit:git-cvsserver[1] for details).
736 gitcvs.dbTableNamePrefix::
737 Database table name prefix. Prepended to the names of any
738 database tables used, allowing a single database to be used
739 for several repositories. Supports variable substitution (see
740 linkgit:git-cvsserver[1] for details). Any non-alphabetic
741 characters will be replaced with underscores.
743 All gitcvs variables except for 'gitcvs.usecrlfattr' and
744 'gitcvs.allbinary' can also be specified as
745 'gitcvs.<access_method>.<varname>' (where 'access_method'
746 is one of "ext" and "pserver") to make them apply only for the given
747 access method.
749 gui.commitmsgwidth::
750 Defines how wide the commit message window is in the
751 linkgit:git-gui[1]. "75" is the default.
753 gui.diffcontext::
754 Specifies how many context lines should be used in calls to diff
755 made by the linkgit:git-gui[1]. The default is "5".
757 gui.matchtrackingbranch::
758 Determines if new branches created with linkgit:git-gui[1] should
759 default to tracking remote branches with matching names or
760 not. Default: "false".
762 gui.newbranchtemplate::
763 Is used as suggested name when creating new branches using the
764 linkgit:git-gui[1].
766 gui.pruneduringfetch::
767 "true" if linkgit:git-gui[1] should prune tracking branches when
768 performing a fetch. The default value is "false".
770 gui.trustmtime::
771 Determines if linkgit:git-gui[1] should trust the file modification
772 timestamp or not. By default the timestamps are not trusted.
774 gui.spellingdictionary::
775 Specifies the dictionary used for spell checking commit messages in
776 the linkgit:git-gui[1]. When set to "none" spell checking is turned
777 off.
779 help.browser::
780 Specify the browser that will be used to display help in the
781 'web' format. See linkgit:git-help[1].
783 help.format::
784 Override the default help format used by linkgit:git-help[1].
785 Values 'man', 'info', 'web' and 'html' are supported. 'man' is
786 the default. 'web' and 'html' are the same.
788 http.proxy::
789 Override the HTTP proxy, normally configured using the 'http_proxy'
790 environment variable (see linkgit:curl[1]). This can be overridden
791 on a per-remote basis; see remote.<name>.proxy
793 http.sslVerify::
794 Whether to verify the SSL certificate when fetching or pushing
795 over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
796 variable.
798 http.sslCert::
799 File containing the SSL certificate when fetching or pushing
800 over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
801 variable.
803 http.sslKey::
804 File containing the SSL private key when fetching or pushing
805 over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
806 variable.
808 http.sslCAInfo::
809 File containing the certificates to verify the peer with when
810 fetching or pushing over HTTPS. Can be overridden by the
811 'GIT_SSL_CAINFO' environment variable.
813 http.sslCAPath::
814 Path containing files with the CA certificates to verify the peer
815 with when fetching or pushing over HTTPS. Can be overridden
816 by the 'GIT_SSL_CAPATH' environment variable.
818 http.maxRequests::
819 How many HTTP requests to launch in parallel. Can be overridden
820 by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
822 http.lowSpeedLimit, http.lowSpeedTime::
823 If the HTTP transfer speed is less than 'http.lowSpeedLimit'
824 for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
825 Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
826 'GIT_HTTP_LOW_SPEED_TIME' environment variables.
828 http.noEPSV::
829 A boolean which disables using of EPSV ftp command by curl.
830 This can helpful with some "poor" ftp servers which don't
831 support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
832 environment variable. Default is false (curl will use EPSV).
834 i18n.commitEncoding::
835 Character encoding the commit messages are stored in; git itself
836 does not care per se, but this information is necessary e.g. when
837 importing commits from emails or in the gitk graphical history
838 browser (and possibly at other places in the future or in other
839 porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
841 i18n.logOutputEncoding::
842 Character encoding the commit messages are converted to when
843 running 'git-log' and friends.
845 instaweb.browser::
846 Specify the program that will be used to browse your working
847 repository in gitweb. See linkgit:git-instaweb[1].
849 instaweb.httpd::
850 The HTTP daemon command-line to start gitweb on your working
851 repository. See linkgit:git-instaweb[1].
853 instaweb.local::
854 If true the web server started by linkgit:git-instaweb[1] will
855 be bound to the local IP (
857 instaweb.modulepath::
858 The module path for an apache httpd used by linkgit:git-instaweb[1].
860 instaweb.port::
861 The port number to bind the gitweb httpd to. See
862 linkgit:git-instaweb[1].
865 Set default date-time mode for the log command. Setting
866 value is similar to using 'git-log'\'s --date option. The value is one of the
867 following alternatives: {relative,local,default,iso,rfc,short}.
868 See linkgit:git-log[1].
870 log.showroot::
871 If true, the initial commit will be shown as a big creation event.
872 This is equivalent to a diff against an empty tree.
873 Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
874 normally hide the root commit will now show it. True by default.
876 man.viewer::
877 Specify the programs that may be used to display help in the
878 'man' format. See linkgit:git-help[1].
880 include::merge-config.txt[]
882 man.<tool>.cmd::
883 Specify the command to invoke the specified man viewer. The
884 specified command is evaluated in shell with the man page
885 passed as argument. (See linkgit:git-help[1].)
887 man.<tool>.path::
888 Override the path for the given tool that may be used to
889 display help in the 'man' format. See linkgit:git-help[1].
891 mergetool.<tool>.path::
892 Override the path for the given tool. This is useful in case
893 your tool is not in the PATH.
895 mergetool.<tool>.cmd::
896 Specify the command to invoke the specified merge tool. The
897 specified command is evaluated in shell with the following
898 variables available: 'BASE' is the name of a temporary file
899 containing the common base of the files to be merged, if available;
900 'LOCAL' is the name of a temporary file containing the contents of
901 the file on the current branch; 'REMOTE' is the name of a temporary
902 file containing the contents of the file from the branch being
903 merged; 'MERGED' contains the name of the file to which the merge
904 tool should write the results of a successful merge.
906 mergetool.<tool>.trustExitCode::
907 For a custom merge command, specify whether the exit code of
908 the merge command can be used to determine whether the merge was
909 successful. If this is not set to true then the merge target file
910 timestamp is checked and the merge assumed to have been successful
911 if the file has been updated, otherwise the user is prompted to
912 indicate the success of the merge.
914 mergetool.keepBackup::
915 After performing a merge, the original file with conflict markers
916 can be saved as a file with a `.orig` extension. If this variable
917 is set to `false` then this file is not preserved. Defaults to
918 `true` (i.e. keep the backup files).
920 pack.window::
921 The size of the window used by linkgit:git-pack-objects[1] when no
922 window size is given on the command line. Defaults to 10.
924 pack.depth::
925 The maximum delta depth used by linkgit:git-pack-objects[1] when no
926 maximum depth is given on the command line. Defaults to 50.
928 pack.windowMemory::
929 The window memory size limit used by linkgit:git-pack-objects[1]
930 when no limit is given on the command line. The value can be
931 suffixed with "k", "m", or "g". Defaults to 0, meaning no
932 limit.
934 pack.compression::
935 An integer -1..9, indicating the compression level for objects
936 in a pack file. -1 is the zlib default. 0 means no
937 compression, and 1..9 are various speed/size tradeoffs, 9 being
938 slowest. If not set, defaults to core.compression. If that is
939 not set, defaults to -1, the zlib default, which is "a default
940 compromise between speed and compression (currently equivalent
941 to level 6)."
943 pack.deltaCacheSize::
944 The maximum memory in bytes used for caching deltas in
945 linkgit:git-pack-objects[1].
946 A value of 0 means no limit. Defaults to 0.
948 pack.deltaCacheLimit::
949 The maximum size of a delta, that is cached in
950 linkgit:git-pack-objects[1]. Defaults to 1000.
952 pack.threads::
953 Specifies the number of threads to spawn when searching for best
954 delta matches. This requires that linkgit:git-pack-objects[1]
955 be compiled with pthreads otherwise this option is ignored with a
956 warning. This is meant to reduce packing time on multiprocessor
957 machines. The required amount of memory for the delta search window
958 is however multiplied by the number of threads.
959 Specifying 0 will cause git to auto-detect the number of CPU's
960 and set the number of threads accordingly.
962 pack.indexVersion::
963 Specify the default pack index version. Valid values are 1 for
964 legacy pack index used by Git versions prior to 1.5.2, and 2 for
965 the new pack index with capabilities for packs larger than 4 GB
966 as well as proper protection against the repacking of corrupted
967 packs. Version 2 is the default. Note that version 2 is enforced
968 and this config option ignored whenever the corresponding pack is
969 larger than 2 GB.
970 +
971 If you have an old git that does not understand the version 2 `{asterisk}.idx` file,
972 cloning or fetching over a non native protocol (e.g. "http" and "rsync")
973 that will copy both `{asterisk}.pack` file and corresponding `{asterisk}.idx` file from the
974 other side may give you a repository that cannot be accessed with your
975 older version of git. If the `{asterisk}.pack` file is smaller than 2 GB, however,
976 you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
977 the `{asterisk}.idx` file.
979 pack.packSizeLimit::
980 The default maximum size of a pack. This setting only affects
981 packing to a file, i.e. the git:// protocol is unaffected. It
982 can be overridden by the `\--max-pack-size` option of
983 linkgit:git-repack[1].
985 pager.<cmd>::
986 Allows to set your own pager preferences for each command, overriding
987 the default. If `\--pager` or `\--no-pager` is specified on the command
988 line, it takes precedence over this option.
990 pull.octopus::
991 The default merge strategy to use when pulling multiple branches
992 at once.
994 pull.twohead::
995 The default merge strategy to use when pulling a single branch.
997 remote.<name>.url::
998 The URL of a remote repository. See linkgit:git-fetch[1] or
999 linkgit:git-push[1].
1001 remote.<name>.proxy::
1002 For remotes that require curl (http, https and ftp), the URL to
1003 the proxy to use for that remote. Set to the empty string to
1004 disable proxying for that remote.
1006 remote.<name>.fetch::
1007 The default set of "refspec" for linkgit:git-fetch[1]. See
1008 linkgit:git-fetch[1].
1010 remote.<name>.push::
1011 The default set of "refspec" for linkgit:git-push[1]. See
1012 linkgit:git-push[1].
1014 remote.<name>.mirror::
1015 If true, pushing to this remote will automatically behave
1016 as if the `\--mirror` option was given on the command line.
1018 remote.<name>.skipDefaultUpdate::
1019 If true, this remote will be skipped by default when updating
1020 using the update subcommand of linkgit:git-remote[1].
1022 remote.<name>.receivepack::
1023 The default program to execute on the remote side when pushing. See
1024 option \--receive-pack of linkgit:git-push[1].
1026 remote.<name>.uploadpack::
1027 The default program to execute on the remote side when fetching. See
1028 option \--upload-pack of linkgit:git-fetch-pack[1].
1030 remote.<name>.tagopt::
1031 Setting this value to \--no-tags disables automatic tag following when
1032 fetching from remote <name>
1034 remotes.<group>::
1035 The list of remotes which are fetched by "git remote update
1036 <group>". See linkgit:git-remote[1].
1038 repack.usedeltabaseoffset::
1039 By default, linkgit:git-repack[1] creates packs that use
1040 delta-base offset. If you need to share your repository with
1041 git older than version 1.4.4, either directly or via a dumb
1042 protocol such as http, then you need to set this option to
1043 "false" and repack. Access from old git versions over the
1044 native protocol are unaffected by this option.
1046 showbranch.default::
1047 The default set of branches for linkgit:git-show-branch[1].
1048 See linkgit:git-show-branch[1].
1050 status.relativePaths::
1051 By default, linkgit:git-status[1] shows paths relative to the
1052 current directory. Setting this variable to `false` shows paths
1053 relative to the repository root (this was the default for git
1054 prior to v1.5.4).
1056 status.showUntrackedFiles::
1057 By default, linkgit:git-status[1] and linkgit:git-commit[1] show
1058 files which are not currently tracked by Git. Directories which
1059 contain only untracked files, are shown with the directory name
1060 only. Showing untracked files means that Git needs to lstat() all
1061 all the files in the whole repository, which might be slow on some
1062 systems. So, this variable controls how the commands displays
1063 the untracked files. Possible values are:
1064 +
1065 --
1066 - 'no' - Show no untracked files
1067 - 'normal' - Shows untracked files and directories
1068 - 'all' - Shows also individual files in untracked directories.
1069 --
1070 +
1071 If this variable is not specified, it defaults to 'normal'.
1072 This variable can be overridden with the -u|--untracked-files option
1073 of linkgit:git-status[1] and linkgit:git-commit[1].
1075 tar.umask::
1076 This variable can be used to restrict the permission bits of
1077 tar archive entries. The default is 0002, which turns off the
1078 world write bit. The special value "user" indicates that the
1079 archiving user's umask will be used instead. See umask(2) and
1080 linkgit:git-archive[1].
1082 url.<base>.insteadOf::
1083 Any URL that starts with this value will be rewritten to
1084 start, instead, with <base>. In cases where some site serves a
1085 large number of repositories, and serves them with multiple
1086 access methods, and some users need to use different access
1087 methods, this feature allows people to specify any of the
1088 equivalent URLs and have git automatically rewrite the URL to
1089 the best alternative for the particular user, even for a
1090 never-before-seen repository on the site. When more than one
1091 insteadOf strings match a given URL, the longest match is used.
1094 Your email address to be recorded in any newly created commits.
1095 Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
1096 'EMAIL' environment variables. See linkgit:git-commit-tree[1].
1099 Your full name to be recorded in any newly created commits.
1100 Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
1101 environment variables. See linkgit:git-commit-tree[1].
1103 user.signingkey::
1104 If linkgit:git-tag[1] is not selecting the key you want it to
1105 automatically when creating a signed tag, you can override the
1106 default selection with this variable. This option is passed
1107 unchanged to gpg's --local-user parameter, so you may specify a key
1108 using any method that gpg supports.
1110 imap::
1111 The configuration variables in the 'imap' section are described
1112 in linkgit:git-imap-send[1].
1114 receive.fsckObjects::
1115 If it is set to true, git-receive-pack will check all received
1116 objects. It will abort in the case of a malformed object or a
1117 broken link. The result of an abort are only dangling objects.
1118 Defaults to false.
1120 receive.unpackLimit::
1121 If the number of objects received in a push is below this
1122 limit then the objects will be unpacked into loose object
1123 files. However if the number of received objects equals or
1124 exceeds this limit then the received pack will be stored as
1125 a pack, after adding any missing delta bases. Storing the
1126 pack from a push can make the push operation complete faster,
1127 especially on slow filesystems. If not set, the value of
1128 `transfer.unpackLimit` is used instead.
1130 receive.denyNonFastForwards::
1131 If set to true, git-receive-pack will deny a ref update which is
1132 not a fast forward. Use this to prevent such an update via a push,
1133 even if that push is forced. This configuration variable is
1134 set when initializing a shared repository.
1136 transfer.unpackLimit::
1137 When `fetch.unpackLimit` or `receive.unpackLimit` are
1138 not set, the value of this variable is used instead.
1139 The default value is 100.
1141 web.browser::
1142 Specify a web browser that may be used by some commands.
1143 Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
1144 may use it.
