- Use octal escape sequences (e.g. "\302\242"), not hexadecimal (e.g.
"\xc2\xa2") in printf format strings, since hexadecimal escape
sequences are not portable.
- Prefer succinctness and matter-of-factly describing functionality
in the abstract. E.g.
- --short:: Emit output in the short-format.
+ `--short`:: Emit output in the short-format.
and avoid something like these overly verbose alternatives:
- --short:: Use this to emit output in the short-format.
- --short:: You can use this to get output in the short-format.
- --short:: A user who prefers shorter output could....
- --short:: Should a person and/or program want shorter output, he

This practice often eliminates the need to involve human actors in
your description, but it is a good practice regardless of the
addressing the hypothetical user, and possibly "we" when
discussing how the program might react to the user. E.g.
- You can use this option instead of --xyz, but we might remove

- A few commented examples follow to provide reference when writing or
- modifying command usage strings and synopsis sections in the manual

- Placeholders are spelled in lowercase and enclosed in angle brackets:
- <file>
- --sort=<key>
- --abbrev[=<n>]
+Markup:
+
+ Literal parts (e.g. use of command-line options, command names,
+ branch names, URLs, pathnames (files and directories), configuration and
+ environment variables) must be typeset as verbatim (i.e. wrapped with
+ backticks):
+ `--pretty=oneline`
+ `git rev-list`
+ `remote.pushDefault`
+ `http://git.example.com`
+ `.git/config`
+ `GIT_DIR`
+ `HEAD`
+ `umask`(2)
+
+ An environment variable must be prefixed with "$" only when referring to its
+ value and not when referring to the variable itself, in this case there is
+ nothing to add except the backticks:
+ `GIT_DIR` is specified
+ `$GIT_DIR/hooks/pre-receive`
+
+ Word phrases enclosed in `backtick characters` are rendered literally
+ and will not be further expanded. The use of `backticks` to achieve the
+ previous rule means that literal examples should not use AsciiDoc
+ escapes.
+ Correct:
+ `--pretty=oneline`
+ Incorrect:
+ `\--pretty=oneline`
+
+ Placeholders are spelled in lowercase and enclosed in
+ angle brackets surrounded by underscores:
+ _<file>_
+ _<commit>_
If a placeholder has multiple words, they are separated by dashes:
- <new-branch-name>
- --template=<template-directory>
+ _<new-branch-name>_
+ _<template-directory>_
+
+ A placeholder is not enclosed in backticks, as it is not a literal.
- When a placeholder is cited in text paragraph, it is enclosed in angle
- brackets to remind the reader the reference in the synopsis section.
- For better visibility, the placeholder is typeset in italics:
- The _<file>_ to be added.
+ When needed, use a distinctive identifier for placeholders, usually
+ made of a qualification and a type:
+ _<git-dir>_
+ _<key-id>_
+
+ When literal and placeholders are mixed, each markup is applied for
+ each sub-entity. If they are stuck, a special markup, called
+ unconstrained formatting is required.
+ Unconstrained formating for placeholders is __<like-this>__
+ Unconstrained formatting for literal formatting is ++like this++
+ `--jobs` _<n>_
+ ++--sort=++__<key>__
+ __<directory>__++/.git++
+ ++remote.++__<name>__++.mirror++
+
+ caveat: ++ unconstrained format is not verbatim and may expand
+ content. Use Asciidoc escapes inside them.
+
+Synopsis Syntax
+
+ Syntax grammar is formatted neither as literal nor as placeholder.
+
+ A few commented examples follow to provide reference when writing or
+ modifying command usage strings and synopsis sections in the manual
+ pages:
Possibility of multiple occurrences is indicated by three dots:
- <file>...
+ _<file>_...
(One or more of <file>.)
Optional parts are enclosed in square brackets:
- [<file>...]
+ [_<file>_...]
(Zero or more of <file>.)
- --exec-path[=<path>]
+ ++--exec-path++[++=++__<path>__]
(Option with an optional argument. Note that the "=" is inside the
brackets.)
- [<patch>...]
+ [_<patch>_...]
(Zero or more of <patch>. Note that the dots are inside, not
outside the brackets.)
Multiple alternatives are indicated with vertical bars:
- [-q | --quiet]
- [--utf8 | --no-utf8]
+ [`-q` | `--quiet`]
+ [`--utf8` | `--no-utf8`]
Use spacing around "|" token(s), but not immediately after opening or
before closing a [] or () pair:
- Do: [-q | --quiet]
- Don't: [-q|--quiet]
+ Do: [`-q` | `--quiet`]
+ Don't: [`-q`|`--quiet`]
Don't use spacing around "|" tokens when they're used to separate the
alternate arguments of an option:
- Do: --track[=(direct|inherit)]
- Don't: --track[=(direct | inherit)]
+ Do: ++--track++[++=++(`direct`|`inherit`)]`
+ Don't: ++--track++[++=++(`direct` | `inherit`)]
Parentheses are used for grouping:
- [(<rev> | <range>)...]
+ [(_<rev>_ | _<range>_)...]
(Any number of either <rev> or <range>. Parens are needed to make
it clear that "..." pertains to both <rev> and <range>.)
- [(-p <parent>)...]
+ [(`-p` _<parent>_)...]
(Any number of option -p, each with one <parent> argument.)
- git remote set-head <name> (-a | -d | <branch>)
+ `git remote set-head` _<name>_ (`-a` | `-d` | _<branch>_)
(One and only one of "-a", "-d" or "<branch>" _must_ (no square
brackets) be provided.)
And a somewhat more contrived example:
- --diff-filter=[(A|C|D|M|R|T|U|X|B)...[*]]
+ `--diff-filter=[(A|C|D|M|R|T|U|X|B)...[*]]`
Here "=" is outside the brackets, because "--diff-filter=" is a
valid usage. "*" has its own pair of brackets, because it can
(optionally) be specified only when one or more of the letters is
the user would type into a shell and use 'Git' (uppercase first letter)
when talking about the version control system and its properties.
- A few commented examples follow to provide reference when writing or
- modifying paragraphs or option/command explanations that contain options
- or commands:
-
- Literal examples (e.g. use of command-line options, command names,
- branch names, URLs, pathnames (files and directories), configuration and
- environment variables) must be typeset in monospace (i.e. wrapped with
- backticks):
- `--pretty=oneline`
- `git rev-list`
- `remote.pushDefault`
- `http://git.example.com`
- `.git/config`
- `GIT_DIR`
- `HEAD`
-
- An environment variable must be prefixed with "$" only when referring to its
- value and not when referring to the variable itself, in this case there is
- nothing to add except the backticks:
- `GIT_DIR` is specified
- `$GIT_DIR/hooks/pre-receive`
-
- Word phrases enclosed in `backtick characters` are rendered literally
- and will not be further expanded. The use of `backticks` to achieve the
- previous rule means that literal examples should not use AsciiDoc
- escapes.
- Correct:
- `--pretty=oneline`
- Incorrect:

-A placeholder is not enclosed in backticks, as it is not a literal.

OPTIONS
-------
--l::
---local::
+`-l`::
+`--local`::
When the repository to clone from is on a local machine,
this flag bypasses the normal "Git aware" transport
mechanism and clones the repository by making a copy of
- HEAD and everything under objects and refs directories.
+ `HEAD` and everything under objects and refs directories.
The files under `.git/objects/` directory are hardlinked
to save space when possible.
+
source repository, similar to running `cp -r src dst` while modifying
`src`.
---no-hardlinks::
+`--no-hardlinks`::
Force the cloning process from a repository on a local
filesystem to copy the files under the `.git/objects`
directory instead of using hardlinks. This may be desirable
if you are trying to make a back-up of your repository.
--s::
---shared::
+`-s`::
+`--shared`::
When the repository to clone is on the local machine,
instead of using hard links, automatically setup
`.git/objects/info/alternates` to share the objects
its source repository, you can simply run `git repack -a` to copy all
objects from the source repository into a pack in the cloned repository.
---reference[-if-able] <repository>::
+`--reference`[`-if-able`] _<repository>_::
If the reference _<repository>_ is on the local machine,
automatically setup `.git/objects/info/alternates` to
obtain objects from the reference _<repository>_. Using
*NOTE*: see the NOTE for the `--shared` option, and also the
`--dissociate` option.
---dissociate::
+`--dissociate`::
Borrow the objects from reference repositories specified
with the `--reference` options only to reduce network
transfer, and stop borrowing from them after a clone is made
same repository, and this option can be used to stop the
borrowing.
--q::
---quiet::
+`-q`::
+`--quiet`::
Operate quietly. Progress is not reported to the standard
error stream.
--v::
---verbose::
+`-v`::
+`--verbose`::
Run verbosely. Does not affect the reporting of progress status
to the standard error stream.
---progress::
+`--progress`::
Progress status is reported on the standard error stream
by default when it is attached to a terminal, unless `--quiet`
is specified. This flag forces progress status even if the
standard error stream is not directed to a terminal.
---server-option=<option>::
+++--server-option=++__<option>__::
Transmit the given string to the server when communicating using
protocol version 2. The given string must not contain a NUL or LF
character. The server's handling of server options, including
unknown ones, is server-specific.
- When multiple `--server-option=<option>` are given, they are all
+ When multiple ++--server-option=++__<option>__ are given, they are all
sent to the other side in the order listed on the command line.
--n::
---no-checkout::
+`-n`::
+`--no-checkout`::
No checkout of HEAD is performed after the clone is complete.
---[no-]reject-shallow::
+`--`[`no-`]`reject-shallow`::
Fail if the source repository is a shallow repository.
The `clone.rejectShallow` configuration variable can be used to
specify the default.
---bare::
+`--bare`::
Make a 'bare' Git repository. That is, instead of
creating _<directory>_ and placing the administrative
- files in `<directory>/.git`, make the _<directory>_
+ files in _<directory>_`/.git`, make the _<directory>_
itself the `$GIT_DIR`. This obviously implies the `--no-checkout`
because there is nowhere to check out the working tree.
Also the branch heads at the remote are copied directly
used, neither remote-tracking branches nor the related
configuration variables are created.
---sparse::
+`--sparse`::
Employ a sparse-checkout, with only files in the toplevel
directory initially being present. The
linkgit:git-sparse-checkout[1] command can be used to grow the
working directory as needed.
---filter=<filter-spec>::
+++--filter=++__<filter-spec>__::
Use the partial clone feature and request that the server sends
a subset of reachable objects according to a given object filter.
When using `--filter`, the supplied _<filter-spec>_ is used for
the partial clone filter. For example, `--filter=blob:none` will
filter out all blobs (file contents) until needed by Git. Also,
- `--filter=blob:limit=<size>` will filter out all blobs of size
+ ++--filter=blob:limit=++__<size>__ will filter out all blobs of size
at least _<size>_. For more details on filter specifications, see
the `--filter` option in linkgit:git-rev-list[1].
---also-filter-submodules::
+`--also-filter-submodules`::
Also apply the partial clone filter to any submodules in the repository.
Requires `--filter` and `--recurse-submodules`. This can be turned on by
default by setting the `clone.filterSubmodules` config option.
---mirror::
+`--mirror`::
Set up a mirror of the source repository. This implies `--bare`.
Compared to `--bare`, `--mirror` not only maps local branches of the
source to local branches of the target, it maps all refs (including
that all these refs are overwritten by a `git remote update` in the
target repository.
--o <name>::
---origin <name>::
+`-o` _<name>_::
+`--origin` _<name>_::
Instead of using the remote name `origin` to keep track of the upstream
repository, use _<name>_. Overrides `clone.defaultRemoteName` from the
config.
--b <name>::
---branch <name>::
+`-b` _<name>_::
+`--branch` _<name>_::
Instead of pointing the newly created HEAD to the branch pointed
to by the cloned repository's HEAD, point to _<name>_ branch
instead. In a non-bare repository, this is the branch that will
`--branch` can also take tags and detaches the HEAD at that commit
in the resulting repository.
--u <upload-pack>::
---upload-pack <upload-pack>::
+`-u` _<upload-pack>_::
+`--upload-pack` _<upload-pack>_::
When given, and the repository to clone from is accessed
via ssh, this specifies a non-default path for the command
run on the other end.
---template=<template-directory>::
+++--template=++__<template-directory>__::
Specify the directory from which templates will be used;
(See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
--c <key>=<value>::
---config <key>=<value>::
+`-c` __<key>__++=++__<value>__::
+`--config` __<key>__++=++__<value>__::
Set a configuration variable in the newly-created repository;
this takes effect immediately after the repository is
initialized, but before the remote history is fetched or any
Due to limitations of the current implementation, some configuration
variables do not take effect until after the initial fetch and checkout.
Configuration variables known to not take effect are:
-`remote.<name>.mirror` and `remote.<name>.tagOpt`. Use the
+++remote.++__<name>__++.mirror++ and ++remote.++__<name>__++.tagOpt++. Use the
corresponding `--mirror` and `--no-tags` options instead.
---depth <depth>::
+`--depth` _<depth>_::
Create a 'shallow' clone with a history truncated to the
specified number of commits. Implies `--single-branch` unless
`--no-single-branch` is given to fetch the histories near the
tips of all branches. If you want to clone submodules shallowly,
also pass `--shallow-submodules`.
---shallow-since=<date>::
+++--shallow-since=++__<date>__::
Create a shallow clone with a history after the specified time.
---shallow-exclude=<revision>::
+++--shallow-exclude=++__<revision>__::
Create a shallow clone with a history, excluding commits
reachable from a specified remote branch or tag. This option
can be specified multiple times.
---[no-]single-branch::
+`--`[`no-`]`single-branch`::
Clone only the history leading to the tip of a single branch,
either specified by the `--branch` option or the primary
branch remote's `HEAD` points at.
branch when `--single-branch` clone was made, no remote-tracking
branch is created.
---no-tags::
+`--no-tags`::
Don't clone any tags, and set
`remote.<remote>.tagOpt=--no-tags` in the config, ensuring
that future `git pull` and `git fetch` operations won't follow
branch. This is useful e.g. to maintain minimal clones of the default
branch of some repository for search indexing.
---recurse-submodules[=<pathspec>]::
+`--recurse-submodules`[`=`{empty}__<pathspec>__]::
After the clone is created, initialize and clone submodules
within based on the provided _<pathspec>_. If no _=<pathspec>_ is
provided, all submodules are initialized and cloned.
not have a worktree/checkout (i.e. if any of `--no-checkout`/`-n`, `--bare`,
or `--mirror` is given)
---[no-]shallow-submodules::
+`--`[`no-`]`shallow-submodules`::
All submodules which are cloned will be shallow with a depth of 1.
---[no-]remote-submodules::
+`--`[`no-`]`remote-submodules`::
All submodules which are cloned will use the status of the submodule's
remote-tracking branch to update the submodule, rather than the
superproject's recorded SHA-1. Equivalent to passing `--remote` to
`git submodule update`.
---separate-git-dir=<git-dir>::
+`--separate-git-dir=`{empty}__<git-dir>__::
Instead of placing the cloned repository where it is supposed
to be, place the cloned repository at the specified directory,
then make a filesystem-agnostic Git symbolic link to there.
The result is Git repository can be separated from working
tree.
---ref-format=<ref-format>::
+`--ref-format=`{empty}__<ref-format>__::
Specify the given ref storage format for the repository. The valid values are:
+
include::ref-storage-format.txt[]
--j <n>::
---jobs <n>::
+`-j` _<n>_::
+`--jobs` _<n>_::
The number of submodules fetched at the same time.
Defaults to the `submodule.fetchJobs` option.
-<repository>::
+_<repository>_::
The (possibly remote) _<repository>_ to clone from. See the
<<URLS,GIT URLS>> section below for more information on specifying
repositories.
-<directory>::
+_<directory>_::
The name of a new directory to clone into. The "humanish"
part of the source repository is used if no _<directory>_ is
explicitly given (`repo` for `/path/to/repo.git` and `foo`
for `host.xz:foo/.git`). Cloning into an existing directory
is only allowed if the directory is empty.
---bundle-uri=<uri>::
+`--bundle-uri=`{empty}__<uri>__::
Before fetching from the remote, fetch a bundle from the given
_<uri>_ and unbundle the data into the local repository. The refs
in the bundle will be stored under the hidden `refs/bundle/*`

+t/Makefile defines a target for each test file, such that you can also use
+shell pattern matching to run a subset of the tests:
+
+ make *checkout*
+
+will run all tests with 'checkout' in their filename.
+
Since the tests all output TAP (see https://testanything.org) they can
be run with any TAP harness. Here's an example of parallel testing
powered by a recent version of prove(1):
Note that we still &&-chain the loop to propagate failures from
earlier commands.
+ - Repeat tests with slightly different arguments in a loop.
+
+ In some cases it may make sense to re-run the same set of tests with
+ different options or commands to ensure that the command behaves
+ despite the different parameters. This can be achieved by looping
+ around a specific parameter:
+
+ for arg in '' "--foo"
+ do
+ test_expect_success "test command ${arg:-without arguments}" '
+ command $arg
+ '
+ done
+
+ Note that while the test title uses double quotes ("), the test body
+ should continue to use single quotes (') to avoid breakage in case the
+ values contain e.g. quoting characters. The loop variable will be
+ accessible regardless of the single quotes as the test body is passed
+ to `eval`.
+
And here are the "don'ts:"
/\bgrep\b.*--file\b/ and err 'grep --file FILE is not portable (use grep -f FILE)';
/\b[ef]grep\b/ and err 'egrep/fgrep obsolescent (use grep -E/-F)';
/\bexport\s+[A-Za-z0-9_]*=/ and err '"export FOO=bar" is not portable (use FOO=bar && export FOO)';
+ /\blocal\s+[A-Za-z0-9_]*=\$([A-Za-z0-9_{]|[(][^(])/ and
+ err q(quote "$val" in 'local var=$val');
/^\s*([A-Z0-9_]+=(\w*|(["']).*?\3)\s+)+(\w+)/ and exists($func{$4}) and
err '"FOO=bar shell_func" assignment extends beyond "shell_func"';
