Add git-for-each-ref: helper for language bindings
This adds a new command, git-for-each-ref. You can have it iterate over refs and have it output various aspects of the objects they refer to. Signed-off-by: Junio C Hamano <junkio@cox.net>

NAME

||||||
|
----
|
||||||
|
git-for-each-ref - Output information on each ref
|
||||||
|
|
||||||
|
SYNOPSIS
|
||||||
|
--------
|
||||||
|
'git-for-each-ref' [--count=<count>]* [--shell|--perl|--python] [--sort=<key>]* [--format=<format>] [<pattern>]
|
||||||
|
|
||||||
|
DESCRIPTION
|
||||||
|
-----------
|
||||||
|
|
||||||
|
Iterate over all refs that match `<pattern>` and show them
|
||||||
|
according to the given `<format>`, after sorting them according
|
||||||
|
to the given set of `<key>`s. If `<max>` is given, stop after
|
||||||
|
showing that many refs. The interporated values in `<format>`
|
||||||
|
can optionally be quoted as string literals in the specified
|
||||||
|
host language.
|
||||||
|
|
||||||
|
OPTIONS
|
||||||
|
-------
|
||||||
|
<count>::
|
||||||
|
By default the command shows all refs that match
|
||||||
|
`<pattern>`. This option makes it stop after showing
|
||||||
|
that many refs.
|
||||||
|
|
||||||
|
<key>::
|
||||||
|
A field name to sort on. Prefix `-` to sort in
|
||||||
|
descending order of the value. When unspecified,
|
||||||
|
`refname` is used. More than one sort keys can be
|
||||||
|
given.
|
||||||
|
|
||||||
|
<format>::
|
||||||
|
A string that interpolates `%(fieldname)` from the
|
||||||
|
object pointed at by a ref being shown. If `fieldname`
|
||||||
|
is prefixed with an asterisk (`*`) and the ref points
|
||||||
|
at a tag object, the value for the field in the object
|
||||||
|
tag refers is used. When unspecified, defaults to
|
||||||
|
`%(refname)`.
|
||||||
|
|
||||||
|
<pattern>::
|
||||||
|
If given, the name of the ref is matched against this
|
||||||
|
using fnmatch(3). Refs that do not match the pattern
|
||||||
|
are not shown.
|
||||||
|
|
||||||
|
--shell, --perl, --python::
|
||||||
|
If given, strings that substitute `%(fieldname)`
|
||||||
|
placeholders are quoted as string literals suitable for
|
||||||
|
the specified host language. This is meant to produce
|
||||||
|
a scriptlet that can directly be `eval`ed.
|
||||||
|
|
||||||
|
|
||||||
|
FIELD NAMES
|
||||||
|
-----------
|
||||||
|
|
||||||
|
Various values from structured fields in referenced objects can
|
||||||
|
be used to interpolate into the resulting output, or as sort
|
||||||
|
keys.
|
||||||
|
|
||||||
|
For all objects, the following names can be used:
|
||||||
|
|
||||||
|
refname::
|
||||||
|
The name of the ref (the part after $GIT_DIR/refs/).
|
||||||
|
|
||||||
|
objecttype::
|
||||||
|
The type of the object (`blob`, `tree`, `commit`, `tag`).
|
||||||
|
|
||||||
|
objectsize::
|
||||||
|
The size of the object (the same as `git-cat-file -s` reports).
|
||||||
|
|
||||||
|
objectname::
|
||||||
|
The object name (aka SHA-1).
|
||||||
|
|
||||||
|
In addition to the above, for commit and tag objects, the header
|
||||||
|
field names (`tree`, `parent`, `object`, `type`, and `tag`) can
|
||||||
|
be used to specify the value in the header field.
|
||||||
|
|
||||||
|
Fields that have name-email-date tuple as its value (`author`,
|
||||||
|
`committer`, and `tagger`) can be suffixed with `name`, `email`,
|
||||||
|
and `date` to extract the named component.
|
||||||
|
|
||||||
|
The first line of the message in a commit and tag object is
|
||||||
|
`subject`, the remaining lines are `body`. The whole message
|
||||||
|
is `contents`.
|
||||||
|
|
||||||
|
For sorting purposes, fields with numeric values sort in numeric
|
||||||
|
order (`objectsize`, `authordate`, `committerdate`, `taggerdate`).
|
||||||
|
All other fields are used to sort in their byte-value order.
|
||||||
|
|
||||||
|
In any case, a field name that refers to a field inapplicable to
|
||||||
|
the object referred by the ref does not cause an error. It
|
||||||
|
returns an empty string instead.
|
||||||
|
|
||||||

||||||
