NAME
|
||||
----
|
||||
git-quiltimport - Applies a quilt patchset onto the current branch
|
||||
|
||||
|
||||
SYNOPSIS
|
||||
--------
|
||||
[verse]
|
||||
'git-quiltimport' [--dry-run] [--author <author>] [--patches <dir>]
|
||||
|
||||
|
||||
DESCRIPTION
|
||||
-----------
|
||||
Applies a quilt patchset onto the current git branch, preserving
|
||||
the patch boundaries, patch order, and patch descriptions present
|
||||
in the quilt patchset.
|
||||
|
||||
For each patch the code attempts to extract the author from the
|
||||
patch description. If that fails it falls back to the author
|
||||
specified with --author. If the --author flag was not given
|
||||
the patch description is displayed and the user is asked to
|
||||
interactively enter the author of the patch.
|
||||
|
||||
If a subject is not found in the patch description the patch name is
|
||||
preserved as the 1 line subject in the git description.
|
||||
|
||||
OPTIONS
|
||||
-------
|
||||
--dry-run::
|
||||
Walk through the patches in the series and warn
|
||||
if we cannot find all of the necessary information to commit
|
||||
a patch. At the time of this writing only missing author
|
||||
information is warned about.
|
||||
|
||||
--author Author Name <Author Email>::
|
||||
The author name and email address to use when no author
|
||||
information can be found in the patch description.
|
||||
|
||||
--patches <dir>::
|
||||
The directory to find the quilt patches and the
|
||||
quilt series file.
|
||||
|
||||
The default for the patch directory is patches
|
||||
or the value of the $QUILT_PATCHES environment
|
||||
variable.
