Many Git porcelainish commands take mixture of flags
|
2005-09-07 21:08:38 +00:00
|
|
|
(i.e. parameters that begin with a dash '-') and parameters
|
2010-01-09 23:33:00 +00:00
|
|
|
meant for the underlying 'git rev-list' command they use internally
|
2008-06-30 18:56:34 +00:00
|
|
|
and flags and parameters for the other commands they use
|
2010-01-09 23:33:00 +00:00
|
|
|
downstream of 'git rev-list'. This command is used to
|
2005-09-07 21:08:38 +00:00
|
|
|
distinguish between them.

Operation Modes
|
|
|
|
~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
Each of these options must appear first on the command line.
|
|
|
|
|
2007-11-04 10:30:53 +00:00
|
|
|
--parseopt::
|
2010-01-09 23:33:00 +00:00
|
|
|
Use 'git rev-parse' in option parsing mode (see PARSEOPT section below).
|
2007-11-04 10:30:53 +00:00
|
|
|
|
2013-07-21 12:49:27 +00:00
|
|
|
--sq-quote::
|
|
|
|
Use 'git rev-parse' in shell quoting mode (see SQ-QUOTE
|
|
|
|
section below). In contrast to the `--sq` option below, this
|
|
|
|
mode does only quoting. Nothing else is done to command input.
|
|
|
|
|
|
|
|
Options for --parseopt
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
2009-04-28 20:29:24 +00:00
|
|
|
--keep-dashdash::
|
2007-11-04 10:30:53 +00:00
|
|
|
Only meaningful in `--parseopt` mode. Tells the option parser to echo
|
|
|
|
out the first `--` met instead of skipping it.
|
|
|
|
|
2009-06-13 23:58:43 +00:00
|
|
|
--stop-at-non-option::
|
|
|
|
Only meaningful in `--parseopt` mode. Lets the option parser stop at
|
|
|
|
the first non-option argument. This can be used to parse sub-commands
|
2010-01-31 13:24:39 +00:00
|
|
|
that take options themselves.
|
2009-06-13 23:58:43 +00:00
|
|
|
|
2013-10-31 11:08:29 +00:00
|
|
|
--stuck-long::
|
|
|
|
Only meaningful in `--parseopt` mode. Output the options in their
|
|
|
|
long form if available, and with their arguments stuck.

|
|
|
'git rev-list' command.

Options for Output
|
|
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
|
2005-09-07 21:08:38 +00:00
|
|
|
--default <arg>::
|
|
|
|
If there is no parameter given by the user, use `<arg>`
|
|
|
|
instead.
|
|
|
|
|
2013-06-16 14:18:17 +00:00
|
|
|
--prefix <arg>::
|
|
|
|
Behave as if 'git rev-parse' was invoked from the `<arg>`
|
|
|
|
subdirectory of the working tree. Any relative filenames are
|
|
|
|
resolved as if they are prefixed by `<arg>` and will be printed
|
|
|
|
in that form.
|
|
|
|
+
|
|
|
|
This can be used to convert arguments to a command run in a subdirectory
|
|
|
|
so that they can still be used after moving to the top-level of the
|
|
|
|
repository. For example:
|
|
|
|
+
|
|
|
|
----
|
|
|
|
prefix=$(git rev-parse --show-prefix)
|
|
|
|
cd "$(git rev-parse --show-toplevel)"
|
|
|
|
eval "set -- $(git rev-parse --sq --prefix "$prefix" "$@")"
|
|
|
|
----
|
|
|
|
|
2005-09-07 21:08:38 +00:00
|
|
|
--verify::
|
2013-03-30 06:44:25 +00:00
|
|
|
Verify that exactly one parameter is provided, and that it
|
|
|
|
can be turned into a raw 20-byte SHA-1 that can be used to
|
|
|
|
access the object database. If so, emit it to the standard
|
|
|
|
output; otherwise, error out.
|
|
|
|
+
|
|
|
|
If you want to make sure that the output actually names an object in
|
|
|
|
your object database and/or can be used as a specific type of object
|
2015-05-13 04:58:06 +00:00
|
|
|
you require, you can add the `^{type}` peeling operator to the parameter.
|
2013-03-30 06:44:25 +00:00
|
|
|
For example, `git rev-parse "$VAR^{commit}"` will make sure `$VAR`
|
|
|
|
names an existing object that is a commit-ish (i.e. a commit, or an
|
|
|
|
annotated tag that points at a commit). To make sure that `$VAR`
|
|
|
|
names an existing object of any type, `git rev-parse "$VAR^{object}"`
|
|
|
|
can be used.
|
2005-09-07 21:08:38 +00:00

|
|
2008-06-08 01:36:09 +00:00
|
|
|
-q::
|
|
|
|
--quiet::
|
2008-04-26 11:57:23 +00:00
|
|
|
Only meaningful in `--verify` mode. Do not output an error
|
|
|
|
message if the first argument is not a valid object name;
|
|
|
|
instead exit with non-zero status silently.
|
2014-09-15 19:07:39 +00:00
|
|
|
SHA-1s for valid object names are printed to stdout on success.
|
2008-04-26 11:57:23 +00:00
|
|
|
|
2005-09-07 21:08:38 +00:00
|
|
|
--sq::
|
|
|
|
Usually the output is made one line per flag and
|
|
|
|
parameter. This option makes output a single line,
|
|
|
|
properly quoted for consumption by shell. Useful when
|
|
|
|
you expect your parameter to contain whitespaces and
|
|
|
|
newlines (e.g. when using pickaxe `-S` with
|
2010-08-20 10:35:03 +00:00
|
|
|
'git diff-{asterisk}'). In contrast to the `--sq-quote` option,
|
2009-04-25 04:55:26 +00:00
|
|
|
the command input is still interpreted as usual.
|
2005-09-07 21:08:38 +00:00

|
|
|
|
|
|
--not::
|
2005-10-05 23:56:31 +00:00
|
|
|
When showing object names, prefix them with '{caret}' and
|
|
|
|
strip '{caret}' prefix from the object names that already have
|
2005-09-07 21:08:38 +00:00
|
|
|
one.
|
|
|
|
|
2013-07-21 12:49:27 +00:00
|
|
|
--abbrev-ref[=(strict|loose)]::
|
|
|
|
A non-ambiguous short name of the objects name.
|
|
|
|
The option core.warnAmbiguousRefs is used to select the strict
|
|
|
|
abbreviation mode.
|
|
|
|
|
|
|
|
--short::
|
|
|
|
--short=number::
|
|
|
|
Instead of outputting the full SHA-1 values of object names try to
|
|
|
|
abbreviate them to a shorter unique name. When no length is specified
|
|
|
|
7 is used. The minimum length is 4.
|
|
|
|
|
2005-09-07 21:08:38 +00:00
|
|
|
--symbolic::
|
2013-04-15 17:49:04 +00:00
|
|
|
Usually the object names are output in SHA-1 form (with
|
2005-10-05 23:56:31 +00:00
|
|
|
possible '{caret}' prefix); this option makes them output in a
|
2005-09-07 21:08:38 +00:00
|
|
|
form as close to the original input as possible.
|
|
|
|
|
2008-01-05 20:09:55 +00:00
|
|
|
--symbolic-full-name::
|
2015-05-13 05:01:38 +00:00
|
|
|
This is similar to --symbolic, but it omits input that
|
2008-01-05 20:09:55 +00:00
|
|
|
are not refs (i.e. branch or tag names; or more
|
|
|
|
explicitly disambiguating "heads/master" form, when you
|
|
|
|
want to name the "master" branch when there is an
|
|
|
|
unfortunately named tag "master"), and show them as full
|
|
|
|
refnames (e.g. "refs/heads/master").

docs: don't talk about $GIT_DIR/refs/ everywhere
It is misleading to say that we pull refs from $GIT_DIR/refs/*, because we
may also consult the packed refs mechanism. These days we tend to treat
the "refs hierarchy" as more of an abstract namespace that happens to be
represented as $GIT_DIR/refs. At best, this is a minor inaccuracy, but at
worst it can confuse users who then look in $GIT_DIR/refs and find that it
is missing some of the refs they expected to see.
This patch drops most uses of "$GIT_DIR/refs/*", changing them into just
"refs/*", under the assumption that users can handle the concept of an
abstract refs namespace. There are a few things to note:
- most cases just dropped the $GIT_DIR/ portion. But for cases where
that left _just_ the word "refs", I changed it to "refs/" to help
indicate that it was a hierarchy. I didn't do the same for longer
paths (e.g., "refs/heads" remained, instead of becoming
"refs/heads/").
- in some cases, no change was made, as the text was explicitly about
unpacked refs (e.g., the discussion in git-pack-refs).
- In some cases it made sense instead to note the existence of packed
refs (e.g., in check-ref-format and rev-parse).

docs: stop using asciidoc no-inline-literal
In asciidoc 7, backticks like `foo` produced a typographic
effect, but did not otherwise affect the syntax. In asciidoc
8, backticks introduce an "inline literal" inside which markup
is not interpreted. To keep compatibility with existing
documents, asciidoc 8 has a "no-inline-literal" attribute to
keep the old behavior. We enabled this so that the
documentation could be built on either version.
It has been several years now, and asciidoc 7 is no longer
in wide use. We can now decide whether or not we want
inline literals on their own merits, which are:
1. The source is much easier to read when the literal
contains punctuation. You can use `master~1` instead
of `master{tilde}1`.
2. They are less error-prone. Because of point (1), we
tend to make mistakes and forget the extra layer of
quoting.
This patch removes the no-inline-literal attribute from the
Makefile and converts every use of backticks in the
documentation to an inline literal (they must be cleaned up,
or the example above would literally show "{tilde}" in the
output).
Problematic sites were found by grepping for '`.*[{\\]' and
examined and fixed manually. The results were then verified
by comparing the output of "html2text" on the set of
generated html pages. Doing so revealed that in addition to
making the source more readable, this patch fixes several
formatting bugs:
- HTML rendering used the ellipsis character instead of
literal "..." in code examples (like "git log A...B")
- some code examples used the right-arrow character
instead of '->' because they failed to quote
- api-config.txt did not quote tilde, and the resulting
HTML contained a bogus snippet like:
<tt><sub></tt> foo <tt></sub>bar</tt>
which caused some parsers to choke and omit whole
sections of the page.
- git-commit.txt confused ``foo`` (backticks inside a
literal) with ``foo'' (matched double-quotes)
- mentions of `A U Thor <author@example.com>` used to
erroneously auto-generate a mailto footnote for
author@example.com
- the description of --word-diff=plain incorrectly showed
the output as "[-removed-] and {added}", not "{+added+}".
- using "prime" notation like:
commit `C` and its replacement `C'`
confused asciidoc into thinking that everything between
the first backtick and the final apostrophe were meant
to be inside matched quotes
- asciidoc got confused by the escaping of some of our
asterisks. In particular,
`credential.\*` and `credential.<url>.\*`
properly escaped the asterisk in the first case, but
literally passed through the backslash in the second
case.

PARSEOPT
|
|
|
|
--------
|
|
|
|
|
2010-01-09 23:33:00 +00:00
|
|
|
In `--parseopt` mode, 'git rev-parse' helps massaging options to bring to shell
|
2007-11-04 10:30:53 +00:00
|
|
|
scripts the same facilities C builtins have. It works as an option normalizer
|
|
|
|
(e.g. splits single switches aggregate values), a bit like `getopt(1)` does.
|
|
|
|
|
|
|
|
It takes on the standard input the specification of the options to parse and
|
2010-07-30 15:01:50 +00:00
|
|
|
understand, and echoes on the standard output a string suitable for `sh(1)` `eval`
|
2007-11-04 10:30:53 +00:00
|
|
|
to replace the arguments with normalized ones. In case of error, it outputs
|
|
|
|
usage on the standard error stream, and exits with code 129.
|
|
|
|
|
2010-07-30 15:01:50 +00:00
|
|
|
Note: Make sure you quote the result when passing it to `eval`. See
|
|
|
|
below for an example.

Input Format
|
|

|
|
|
|
|
2010-01-09 23:33:00 +00:00
|
|
|
'git rev-parse --parseopt' input format is fully text based. It has two parts,
|
2007-11-04 10:30:53 +00:00
|
|
|
separated by a line that contains only `--`. The lines before the separator
|
2014-03-22 09:47:34 +00:00
|
|
|
(should be one or more) are used for the usage.
|
2007-11-04 10:30:53 +00:00
|
|
|
The lines after the separator describe the options.
|
|
|
|
|
|
|
|
Each line of options has this format:
|
|
|
|
|
|
|
|
------------
|
2014-03-23 22:58:12 +00:00
|
|
|
<opt-spec><flags>*<arg-hint>? SP+ help LF
|
2007-11-04 10:30:53 +00:00
|
|
|
------------
|
|
|
|
|
2014-03-23 22:58:12 +00:00
|
|
|
`<opt-spec>`::
|
2007-11-04 10:30:53 +00:00
|
|
|
its format is the short option character, then the long option name
|
|
|
|
separated by a comma. Both parts are not required, though at least one
|
2015-07-14 08:17:44 +00:00
|
|
|
is necessary. May not contain any of the `<flags>` characters.
|
|
|
|
`h,help`, `dry-run` and `f` are examples of correct `<opt-spec>`.
|
2007-11-04 10:30:53 +00:00
|
|
|
|
2008-03-02 08:21:38 +00:00
|
|
|
`<flags>`::
|
|
|
|
`<flags>` are of `*`, `=`, `?` or `!`.
|
|
|
|
* Use `=` if the option takes an argument.
|
|
|
|
|
2013-10-31 11:08:29 +00:00
|
|
|
* Use `?` to mean that the option takes an optional argument. You
|
|
|
|
probably want to use the `--stuck-long` mode to be able to
|
|
|
|
unambiguously parse the optional argument.
|
2008-03-02 08:21:38 +00:00
|
|
|
|
|
|
|
* Use `*` to mean that this option should not be listed in the usage
|
|
|
|
generated for the `-h` argument. It's shown for `--help-all` as
|
2008-05-02 03:30:47 +00:00
|
|
|
documented in linkgit:gitcli[7].
|
2008-03-02 08:21:38 +00:00
|
|
|
|
|
|
|
* Use `!` to not make the corresponding negated long option available.
|
2007-11-04 10:30:53 +00:00
|
|
|
|
2014-03-23 22:58:12 +00:00
|
|
|
`<arg-hint>`::
|
|
|
|
`<arg-hint>`, if specified, is used as a name of the argument in the
|
|
|
|
help output, for options that take arguments. `<arg-hint>` is
|
|
|
|
terminated by the first whitespace. It is customary to use a
|
|
|
|
dash to separate words in a multi-word argument hint.
|
2014-03-22 09:47:34 +00:00
|
|
|
|
2007-11-04 10:30:53 +00:00
|
|
|
The remainder of the line, after stripping the spaces, is used
|
|
|
|
as the help associated to the option.
|
|
|
|
|
|
|
|
Blank lines are ignored, and lines that don't match this specification are used
|
|
|
|
as option group headers (start the line with a space to create such
|
|
|
|
lines on purpose).

SQ-QUOTE
|
|
|
|
--------
|
|
|
|
|
2010-01-09 23:33:00 +00:00
|
|
|
In `--sq-quote` mode, 'git rev-parse' echoes on the standard output a
|
2009-04-25 04:55:26 +00:00
|
|
|
single line suitable for `sh(1)` `eval`. This line is made by
|
|
|
|
normalizing the arguments following `--sq-quote`. Nothing other than
|
|
|
|
quoting the arguments is done.
|
|
|
|
|
|
|
|
If you want command input to still be interpreted as usual by
|
2010-01-09 23:33:00 +00:00
|
|
|
'git rev-parse' before the output is shell quoted, see the `--sq`
|
2009-04-25 04:55:26 +00:00
|
|
|
option.

|
$ git rev-parse --verify HEAD
|
|
|
|
------------
|
|
|
|

|
|
|
------------
|
|
|
|
+
|
|
|
|
This will error out if $REV is empty or not a valid revision.
|
|
|
|
|
2013-03-30 06:44:25 +00:00
