quilt - tool to manage series of patches

SYNOPSIS

quilt [-h] command [options]

DESCRIPTION

Quilt is a tool to manage large sets of patches by keeping track of the changes each patch
makes. Patches can be applied, un-applied, refreshed, etc. The key philosophical concept
is that your primary output is patches.

With quilt, all work occurs within a single directory tree. Commands can be invoked from
anywhere within the source tree. They are of the form quilt cmd similar to CVS, svn or git
commands. They can be abbreviated as long as the specified part of the command is unique.
All commands print some help text with quilt cmd -h.

Quilt manages a stack of patches. Patches are applied incrementally on top of the base
tree plus all preceding patches. They can be pushed on top of the stack (quilt push), and
popped off the stack (quilt pop). Commands are available for querying the contents of the
series file (quilt series, see below), the contents of the stack (quilt applied, quilt
previous, quilt top), and the patches that are not applied at a particular moment (quilt
next, quilt unapplied). By default, most commands apply to the topmost patch on the
stack.

Patch files are located in the patches sub-directory of the source tree (see EXAMPLE OF
WORKING TREE below). The QUILT_PATCHES environment variable can be used to override this
location. When not found in the current directory, that subdirectory is searched
recursively in the parent directories (this is similar to the way git searches for its
configuration files). The patches directory may contain sub-directories. It may also be a
symbolic link instead of a directory.

A file called series contains a list of patch file names that defines the order in which
patches are applied. Unless there are means by which series files can be generated
automatically, it is usually provided along with a set of patches. In this file, each
patch file name is on a separate line. Patch files are identified by path names that are
relative to the patches directory; patches may be in sub-directories below this directory.
Lines in the series file that start with a hash character (#) are ignored. You can also
add a comment after each patch file name, introduced by a space followed by a hash
character. When quilt adds, removes, or renames patches, it automatically updates the
series file. Users of quilt can modify series files while some patches are applied, as
long as the applied patches remain in their original order.

Different series files can be used to assemble patches in different ways, corresponding
for example to different development branches.

Before a patch is applied (or ``pushed on the stack''), copies of all files the patch
modifies are saved to the .pc/patch directory. The patch is added to the list of currently
applied patches (.pc/applied-patches). Later when a patch is regenerated (quilt refresh),
the backup copies in .pc/patch are compared with the current versions of the files in the
source tree using GNU diff.

Documentation related to a patch can be put at the beginning of a patch file. Quilt is
careful to preserve all text that precedes the actual patch when doing a refresh. (This is
limited to patches in unified format; see diff documentation).

The series file is looked up in the .pc directory, in the root of the source tree, and in
the patches directory. The first series file that is found is used. This may also be a
symbolic link, or a file with multiple hard links. Usually, only one series file is used
for a set of patches, so the patches sub-directory is a convenient location.

The .pc directory and its sub-directories cannot be relocated, but it can be a symbolic
link. While patches are applied to the source tree, this directory is essential for many
operations, including taking patches off the stack (quilt pop), and refreshing patches
(quilt refresh). Files in the .pc directory are automatically removed when they are no
longer needed, so there is no need to clean up manually.

QUILT COMMANDS REFERENCE

add [-P patch] {file} ...

Add one or more files to the topmost or named patch. Files must be added to the patch
before being modified. Files that are modified by patches already applied on top of
the specified patch cannot be added.

-P patch

Patch to add files to.

annotate [-P patch] {file}

Print an annotated listing of the specified file showing which patches modify which
lines. Only applied patches are included.

-P patch

Stop checking for changes at the specified rather than the topmost patch.

applied [patch]

Print a list of applied patches, or all patches up to and including the specified
patch in the file series.

delete [-r] [--backup] [patch|-n]

Remove the specified or topmost patch from the series file. If the patch is applied,
quilt will attempt to remove it first. (Only the topmost patch can be removed right
now.)

-n Delete the next patch after topmost, rather than the specified or topmost patch.

-r Remove the deleted patch file from the patches directory as well.

--backup

Rename the patch file to patch~ rather than deleting it. Ignored if not used with
`-r'.

diff [-p n|-p ab] [-u|-U num|-c|-C num] [--combine patch|-z] [-R] [-P patch] [--snapshot]
[--diff=utility] [--no-timestamps] [--no-index] [--sort] [--color[=always|auto|never]]
[file ...]

Produces a diff of the specified file(s) in the topmost or specified patch. If no
files are specified, all files that are modified are included.

-p n
Create a -p n style patch (-p0 or -p1 are supported).

-p ab
Create a -p1 style patch, but use a/file and b/file as the original and new
filenames instead of the default dir.orig/file and dir/file names.

-u, -U num, -c, -C num

Create a unified diff (-u, -U) with num lines of context. Create a context diff
(-c, -C) with num lines of context. The number of context lines defaults to 3.

--no-timestamps

Do not include file timestamps in patch headers.

--no-index

Do not output Index: lines.

-z Write to standard output the changes that have been made relative to the topmost
or specified patch.

-R Create a reverse diff.

-P patch

Create a diff for the specified patch. (Defaults to the topmost patch.)

--combine patch

Create a combined diff for all patches between this patch and the patch specified
with -P. A patch name of `-' is equivalent to specifying the first applied patch.

--snapshot

Diff against snapshot (see `quilt snapshot -h').

--diff=utility

Use the specified utility for generating the diff. The utility is invoked with the
original and new file name as arguments.

--color[=always|auto|never]

Use syntax coloring (auto activates it only if the output is a tty).

--sort
Sort files by their name instead of preserving the original order.

edit file ...

Edit the specified file(s) in $EDITOR after adding it (them) to the topmost patch.

files [-v] [-a] [-l] [--combine patch] [patch]

Print the list of files that the topmost or specified patch changes.

-a List all files in all applied patches.

-l Add patch name to output.

-v Verbose, more user friendly output.

--combine patch

Create a listing for all patches between this patch and the topmost or specified
patch. A patch name of `-' is equivalent to specifying the first applied patch.

fold [-R] [-q] [-f] [-p strip-level]

Integrate the patch read from standard input into the topmost patch: After making sure
that all files modified are part of the topmost patch, the patch is applied with the
specified strip level (which defaults to 1).

-R Apply patch in reverse.

-q Quiet operation.

-f Force apply, even if the patch has rejects. Unless in quiet mode, apply the patch
interactively: the patch utility may ask questions.

-p strip-level

The number of pathname components to strip from file names when applying
patchfile.

fork [new_name]

Fork the topmost patch. Forking a patch means creating a verbatim copy of it under a
new name, and use that new name instead of the original one in the current series.
This is useful when a patch has to be modified, but the original version of it should
be preserved, e.g. because it is used in another series, or for the history. A
typical sequence of commands would be: fork, edit, refresh.

If new_name is missing, the name of the forked patch will be the current patch name,
followed by `-2'. If the patch name already ends in a dash-and-number, the number is
further incremented (e.g., patch.diff, patch-2.diff, patch-3.diff).

graph [--all] [--reduce] [--lines[=num]] [--edge-labels=files] [-T ps] [patch]

Generate a dot(1) directed graph showing the dependencies between applied patches. A
patch depends on another patch if both touch the same file or, with the --lines
option, if their modifications overlap. Unless otherwise specified, the graph includes
all patches that the topmost patch depends on. When a patch name is specified,
instead of the topmost patch, create a graph for the specified patch. The graph will
include all other patches that this patch depends on, as well as all patches that
depend on this patch.

--all
Generate a graph including all applied patches and their dependencies. (Unapplied
patches are not included.)

--reduce

Eliminate transitive edges from the graph.

--lines[=num]

Compute dependencies by looking at the lines the patches modify. Unless a
different num is specified, two lines of context are included.

--edge-labels=files

Label graph edges with the file names that the adjacent patches modify.

-T ps
Directly produce a PostScript output file.

grep [-h|options] {pattern}

Grep through the source files, recursively, skipping patches and quilt meta-
information. If no filename argument is given, the whole source tree is searched.
Please see the grep(1) manual page for options.

-h Print this help. The grep -h option can be passed after a double-dash (--). Search
expressions that start with a dash can be passed after a second double-dash (--
--).

header [-a|-r|-e] [--backup] [--dep3] [--strip-diffstat] [--strip-trailing-whitespace]
[patch]

Print or change the header of the topmost or specified patch.

-a, -r, -e

Append to (-a) or replace (-r) the exiting patch header, or edit (-e) the header
in $EDITOR. If none of these options is given, print the patch header.

--strip-diffstat

Strip diffstat output from the header.

--strip-trailing-whitespace

Strip trailing whitespace at the end of lines of the header.

--backup

Create a backup copy of the old version of a patch as patch~.

--dep3

When editing (-e), insert a template with DEP-3 headers. DEP-3 is
http://dep.debian.net/deps/dep3/ Patch Tagging Guidelines.

import [-p num] [-R] [-P patch] [-f] [-d {o|a|n}] patchfile ...

Import external patches. The patches will be inserted following the current top
patch, and must be pushed after import to apply them.

-p num

Number of directory levels to strip when applying (default=1)

-R

Apply patch in reverse.

-P patch

Patch filename to use inside quilt. This option can only be used when importing a
single patch.

-f Overwrite/update existing patches.

-d {o|a|n}

When overwriting in existing patch, keep the old (o), all (a), or new (n) patch
header. If both patches include headers, this option must be specified. This
option is only effective when -f is used.

The quilt meta-data is now initialized.

mail {--mbox file|--send} [-m text] [-M file] [--prefix prefix] [--sender ...] [--from
...] [--to ...] [--cc ...] [--bcc ...] [--subject ...] [--reply-to message] [first_patch
[last_patch]]

Create mail messages from a specified range of patches, or all patches in the series
file, and either store them in a mailbox file, or send them immediately. The editor is
opened with a template for the introduction. Please see
/usr/share/doc/quilt/README.MAIL for details. When specifying a range of patches, a
first patch name of `-' denotes the first, and a last patch name of `-' denotes the
last patch in the series.

-m text

Text to use as the text in the introduction. When this option is used, the editor
will not be invoked, and the patches will be processed immediately.

-M file

Like the -m option, but read the introduction from file.

--prefix prefix

Use an alternate prefix in the bracketed part of the subjects generated. Defaults
to `patch'.

--mbox file

Store all messages in the specified file in mbox format. The mbox can later be
sent using formail, for example.

--send

Send the messages directly.

--sender

The envelope sender address to use. The address must be of the form
`[email protected]'. No display name is allowed.

--from, --subject

The values for the From and Subject headers to use. If no --from option is given,
the value of the --sender option is used.

--to, --cc, --bcc

Append a recipient to the To, Cc, or Bcc header.

--signature file

Append the specified signature to messages (defaults to ~/.signature if found; use
`-' for no signature).

--reply-to message

Add the appropriate headers to reply to the specified message.

new [-p n|-p ab] {patchname}

Create a new patch with the specified file name, and insert it after the topmost
patch. The name can be prefixed with a sub-directory name, allowing for grouping
related patches together.

-p n
Create a -p n style patch (-p0 or -p1 are supported).

-p ab
Create a -p1 style patch, but use a/file and b/file as the original and new
filenames instead of the default dir.orig/file and dir/file names.

Quilt can be used in sub-directories of a source tree. It determines the root of a
source tree by searching for a patches directory above the current working
directory. Create a patches directory in the intended root directory if quilt
chooses a top-level directory that is too high up in the directory tree.

next [patch]

Print the name of the next patch after the specified or topmost patch in the series
file.

patches [-v] [--color[=always|auto|never]] {file} [files...]

Print the list of patches that modify any of the specified files. (Uses a heuristic to
determine which files are modified by unapplied patches. Note that this heuristic is
much slower than scanning applied patches.)

-v Verbose, more user friendly output.

--color[=always|auto|never]

Use syntax coloring (auto activates it only if the output is a tty).

pop [-afRqv] [num|patch]

Remove patch(es) from the stack of applied patches. Without options, the topmost
patch is removed. When a number is specified, remove the specified number of patches.
When a patch name is specified, remove patches until the specified patch end up on top
of the stack. Patch names may include the patches/ prefix, which means that filename
completion can be used.

-a Remove all applied patches.

-f Force remove. The state before the patch(es) were applied will be restored from
backup files.

-R Always verify if the patch removes cleanly; don't rely on timestamp checks.

-q Quiet operation.

-v Verbose operation.

previous [patch]

Print the name of the previous patch before the specified or topmost patch in the
series file.

push [-afqv] [--merge[=merge|diff3]] [--leave-rejects] [--color[=always|auto|never]]
[num|patch]

Apply patch(es) from the series file. Without options, the next patch in the series
file is applied. When a number is specified, apply the specified number of patches.
When a patch name is specified, apply all patches up to and including the specified
patch. Patch names may include the patches/ prefix, which means that filename
completion can be used. The mtime of all touched files will be exactly the same to
prevent time skews.

-a Apply all patches in the series file.

-q Quiet operation.

-f Force apply, even if the patch has rejects. Unless in quiet mode, apply the patch
interactively: the patch utility may ask questions.

-v Verbose operation.

--fuzz=N

Set the maximum fuzz factor (default: 2).

-m, --merge[=merge|diff3]

Merge the patch file into the original files (see patch(1)).

--leave-rejects

Leave around the reject files patch produced, even if the patch is not actually
applied.

--color[=always|auto|never]

Use syntax coloring (auto activates it only if the output is a tty).

refresh [-p n|-p ab] [-u|-U num|-c|-C num] [-z[new_name]] [-f] [--no-timestamps] [--no-
index] [--diffstat] [--sort] [--backup] [--strip-trailing-whitespace] [patch]

Refreshes the specified patch, or the topmost patch by default. Documentation that
comes before the actual patch in the patch file is retained.

It is possible to refresh patches that are not on top. If any patches on top of the
patch to refresh modify the same files, the script aborts by default. Patches can
still be refreshed with -f. In that case this script will print a warning for each
shadowed file, changes by more recent patches will be ignored, and only changes in
files that have not been modified by any more recent patches will end up in the
specified patch.

-p n
Create a -p n style patch (-p0 or -p1 supported).

-p ab
Create a -p1 style patch, but use a/file and b/file as the original and new
filenames instead of the default dir.orig/file and dir/file names.

-u, -U num, -c, -C num

Create a unified diff (-u, -U) with num lines of context. Create a context diff
(-c, -C) with num lines of context. The number of context lines defaults to 3.

-z[new_name]

Create a new patch containing the changes instead of refreshing the topmost patch.
If no new name is specified, `-2' is added to the original patch name, etc. (See
the fork command.)

--no-timestamps

Do not include file timestamps in patch headers.

--no-index

Do not output Index: lines.

--diffstat

Add a diffstat section to the patch header, or replace the existing diffstat
section.

-f Enforce refreshing of a patch that is not on top.

--backup

Create a backup copy of the old version of a patch as patch~.

--sort
Sort files by their name instead of preserving the original order.

--strip-trailing-whitespace

Strip trailing whitespace at the end of lines.

remove [-P patch] {file} ...

Remove one or more files from the topmost or named patch. Files that are modified by
patches on top of the specified patch cannot be removed.

-P patch

Remove named files from the named patch.

rename [-P patch] new_name

Rename the topmost or named patch.

-P patch

Patch to rename.

revert [-P patch] {file} ...

Revert uncommitted changes to the topmost or named patch for the specified file(s):
after the revert, 'quilt diff -z' will show no differences for those files. Changes to
files that are modified by patches on top of the specified patch cannot be reverted.

-P patch

Revert changes in the named patch.

series [--color[=always|auto|never]] [-v]

Print the names of all patches in the series file.

--color[=always|auto|never]

Use syntax coloring (auto activates it only if the output is a tty).

-v Verbose, more user friendly output.

setup [-d path-prefix] [-v] [--sourcedir dir] [--fuzz=N] {specfile|seriesfile}

Initializes a source tree from an rpm spec file or a quilt series file.

-d Optional path prefix for the resulting source tree.

--sourcedir

Directory that contains the package sources. Defaults to `.'.

-v Verbose debug output.

--fuzz=N

Set the maximum fuzz factor (needs rpm 4.6 or later).

shell [command]

Launch a shell in a duplicate environment. After exiting the shell, any modifications
made in this environment are applied to the topmost patch.

If a command is specified, it is executed instead of launching the shell.

snapshot [-d]

Take a snapshot of the current working state. After taking the snapshot, the tree can
be modified in the usual ways, including pushing and popping patches. A diff against
the tree at the moment of the snapshot can be generated with `quilt diff --snapshot'.

-d Only remove current snapshot.

top

Print the name of the topmost patch on the current stack of applied patches.

unapplied [patch]

Print a list of patches that are not applied, or all patches that follow the specified
patch in the series file.

upgrade

Upgrade the meta-data in a working tree from an old version of quilt to the current
version. This command is only needed when the quilt meta-data format has changed, and
the working tree still contains old-format meta-data. In that case, quilt will request
to run `quilt upgrade'.

COMMON OPTIONS TO ALL COMMANDS

--trace

Runs the command in bash trace mode (-x). For internal debugging.

--quiltrc file

Use the specified configuration file instead of ~/.quiltrc (or /etc/quilt.quiltrc
if ~/.quiltrc does not exist). See the pdf documentation for details about its
possible contents. The special value "-" causes quilt not to read any
configuration file.

--version

Print the version number and exit immediately.

EXIT STATUS

The exit status is 0 if the sub-command was successfully executed, and 1 in case of error.

An exit status of 2 denotes that quilt did not do anything to complete the command. This
happens in particular when asking to push when the whole stack is already pushed, or
asking to pop when the whole stack is already popped. This behavior is intended to ease
the scripting around quilt.

EXAMPLE OF WORKING TREE

work/

The patches/ directory is precious as it contains all your patches as well as the order in
which it should be applied.

The .pc/ directory contains some metadata about the current state of your patch serie.
Changing its content is not advised. This directory can usually be regenerated from the
initial files and the content of the patches/ directory (provided that all patches were
regenerated before the removal).

EXAMPLE

Please refer to the pdf documentation for a full example of use.

CONFIGURATION FILE

Upon startup, quilt evaluates the file .quiltrc in the user's home directory, or the file
specified with the --quiltrc option. This file is a regular bash script. Default options
can be passed to any COMMAND by defining a QUILT_${COMMAND}_ARGS variable. For example,
QUILT_DIFF_ARGS="--color=auto" causes the output of quilt diff to be syntax colored when
writing to a terminal.

In addition to that, quilt recognizes the following variables:

EDITOR

The program to run to edit files. If it isn't redefined in the configuration file,
$EDITOR as defined in the environment will be used.

LESS

The arguments used to invoke the pager. Inherits the existing value of $LESS if LESS
is already set in the environment, otherwise defaults to "-FRSX".

QUILT_DIFF_OPTS

Additional options that quilt shall pass to GNU diff when generating patches. A useful
setting for C source code is "-p", which causes GNU diff to show in the resulting
patch which function a change is in.

QUILT_PATCH_OPTS

Additional options that quilt shall pass to GNU patch when applying patches. For
example, recent versions of GNU patch support the "--reject-format=unified" option for
generating reject files in unified diff style (older patch versions used "--unified-
reject-files" for that).

You may also want to add the "-E" option if you have issues with quilt not deleting
empty files when you think it should. The documentation of GNU patch says that
"normally this option is unnecessary", but when patch is in POSIX mode or if the patch
format doesn't allow to distinguish empty files from deleted files, patch deletes
empty files only if the -E option is given. Beware that when passing -E to patch,
quilt will no longer be able to deal with empty files, which is why using -E is no
longer the default.

QUILT_DIFFSTAT_OPTS

Additional options that quilt shall pass to diffstat when generating patch statistics.
For example, "-f0" can be used for an alternative output format. Recent versions of
diffstat also support alternative rounding methods ("-r1", "-r2").

QUILT_PATCHES

The location of patch files, defaulting to "patches".

QUILT_SERIES

The name of the series file, defaulting to "series". Unless an absolute path is used,
the search algorithm described above applies.

QUILT_PATCHES_PREFIX

If set to anything, quilt will prefix patch names it prints with their directory
(QUILT_PATCHES).

QUILT_NO_DIFF_INDEX

By default, quilt prepends an Index: line to the patches it generates. If this
variable is set to anything, no line is prepended. This is a shortcut to adding --no-
index to both QUILT_DIFF_ARGS and QUILT_REFRESH_ARGS.

QUILT_NO_DIFF_TIMESTAMPS

By default, quilt includes timestamps in headers when generating patches. If this
variable is set to anything, no timestamp will be included. This is a shortcut to
adding --no-timestamps to both QUILT_DIFF_ARGS and QUILT_REFRESH_ARGS.

QUILT_PAGER

The pager quilt shall use for commands which produce paginated output. If unset, the
values of GIT_PAGER or PAGER is used. If none of these variables is set, "less -R" is
used. An empty value indicates that no pager should be used.

QUILT_COLORS

By default, quilt uses its predefined color set in order to be more comprehensible
when distiguishing various types of patches, eg. applied/unapplied, failed, etc.

To override one or more color settings, set the QUILT_COLORS variable in following
syntax - colon (:) separated list of elements, each being of the form <format
name>=<foreground color>[;<background color>]

Format names with their respective default values are listed below, along with their
usage(s). Color codes(values) are standard bash coloring escape codes. See more at
http://tldp.org/LDP/abs/html/colorizing.html#AEN20229

diff_hdr Used in 'quilt diff' to color the index line. Defaults to 32 (green).

diff_add Used in 'quilt diff' to color added lines. Defaults to 36 (azure).

diff_mod Used in 'quilt diff' to color modified lines. Defaults to 35 (purple).

diff_rem Used in 'quilt diff' to color removed lines. Defaults to 35 (purple).

diff_hunk Used in 'quilt diff' to color hunk header. Defaults to 33 (brown/orange).

diff_ctx Used in 'quilt diff' to color the text after end of hunk header (diff
--show-c-function generates this). Defaults to 35 (purple).

diff_cctx Used in 'quilt diff' to color the 15-asterisk sequence before or after a
hunk. Defaults to 33 (brown/orange).

patch_fuzz
Used in 'quilt push' to color the patch fuzz information. Defaults to 35
(purple).

patch_fail
Used in 'quilt push' to color the fail message. Defaults to 31 (red).

series_app
Used in 'quilt series' and 'quilt patches' to color the applied patch names.
Defaults to 32 (green).

series_top
Used in 'quilt series' and 'quilt patches' to color the top patch name.
Defaults to 33 (brown/orange).

series_una
Used in 'quilt series' and 'quilt patches' to color unapplied patch names.
Defaults to 0 (no special color).

In addition, the clear format name is used to turn off special coloring. Its value is
0; it is not advised to modify it.

The content of QUILT_COLORS supersedes default values. So the value diff_hdr=35;44
will get you the diff headers in magenta over blue instead of the default green over
unchanged background. For that, add the following content to ~/.quiltrc (or
/etc/quilt.quiltrc):

QUILT_DIFF_ARGS="--color"
QUILT_COLORS='diff_hdr=35;44'

AUTHORS

Quilt started as a series of scripts written by Andrew Morton (patch-scripts). Based on
Andrew's ideas, Andreas Gruenbacher completely rewrote the scripts, with the help of
several other contributors (see AUTHORS file in the distribution).

This man page was written by Martin Quinson, based on information found in the pdf
documentation, and in the help messages of each commands.
