Magit User Manual
*****************
Magit is an interface to the version control system Git, implemented as
an extension to Emacs. Magit supports GNU Emacs version 22 or later.
It may work with other emacsen, but Magit developers do not intend to
investigate and fix bugs that only appear in unsupported versions.
Patches to fix bugs in other emacsen or volunteers to maintain
compatibility are still welcome.

1 Introduction
**************
With Magit, you can inspect and modify your Git repositories with
Emacs. You can review and commit the changes you have made to the
tracked files, for example, and you can browse the history of past
changes. There is support for cherry picking, reverting, merging,
rebasing, and other common Git operations.
Magit is not a complete interface to Git; it just aims to make the
most common Git operations convenient. Thus, Magit will likely not
save you from learning Git itself.
This manual provides a tour of all Magit features. It does not give
an introduction to version control in general, or to Git in particular.
The main entry point to Magit is `M-x magit-status', which will put
you in Magit's status buffer. You will be using it frequently, so it
is probably a good idea to bind `magit-status' to a key of your choice.
In addition to the status buffer, Magit will also create buffers that
show lists of commits, buffers with diffs, and other kinds of buffers.
All these buffers are in `magit-mode' and have the same key bindings.
Not all commands make sense in all contexts, but a given key will
always do the same thing in all Magit buffers.
Naturally, Magit runs the `git' command to do most of the work. The
`*magit-process*' buffer contains the transcript of the most recent
command. You can switch to it with `$'.

3 Sections
**********
All Magit buffers are structured into nested 'sections'. These
sections can be hidden and shown individually. When a section is
hidden, only its first line is shown and all its children are
completely invisible.
The most fine-grained way to control the visibility of sections is
the `TAB' key. It will to toggle the current section (the section that
contains point) between being hidden and being shown.
Typing `S-TAB' toggles the visibility of the children of the current
section. When all of them are shown, they will all be hidden.
Otherwise, when some or all are hidden, they will all be shown.
The digit keys `1', `2', `3', and `4' control the visibility of
sections based on levels. Hitting `2', for example, will show sections
on levels one and two, and will hide sections on level 3. However,
only sections that are a parent or child of the current section are
affected.
For example, when the current section is on level 3 and you hit `1',
the grand-parent of the current section (which is on level one) will be
shown, and the parent of the current section (level 2) will be hidden.
The visibility of no other section will be changed.
This sounds a bit complicated, but you'll figure it out.
Using `M-1', `M-2', `M-3', and `M-4' is similar to the unmodified
digits, but now all sections on the respective level are affected,
regardless of whether or not they are related to the current section.
For example, `M-1' will only show the first lines of the top-level
sections and will hide everything else. Typing `M-4' on the other hand
will show everything.
Because of the way the status buffer is set up, some changes to
section visibility are more common than others. Files are on level 2
and diff hunks are on level 4. Thus, you can type `2' to collapse the
diff of the current file, and `M-2' to collapse all files. This
returns the status buffer to its default setup and is a quick way to
unclutter it after drilling down into the modified files.
Because `2' and `M-2' are so common in the status buffer, they are
bound to additional, more mnemonic keys: `M-h' (hide) and `M-H' (hide
all). Likewise `4' and `M-4' are also available as `M-s' (show) and
`M-S' (show all).
In other buffers than the status buffer, `M-h', `M-H', `M-s', and
`M-S' might work on different levels than on 2 and 4, but they keep
their general meaning: `M-H' hides all detail, and `M-S' shows
everything.

File: magit.info, Node: Status, Next: Untracked files, Prev: Sections, Up: Top
4 Status
********
Running `M-x magit-status' displays the main interface of Magit, the
status buffer. You can have multiple status buffers active at the same
time, each associated with its own Git repository.
When invoking `M-x magit-status' from within a Git repository, it
will switch to the status buffer of that repository. Otherwise, it
will prompt for a directory. With a prefix argument, it will always
prompt.
You can set `magit-repo-dirs' to customize how `magit-status' asks
for the repository to work on. When `magit-repo-dirs' is nil,
`magit-status' will simply ask for a directory.
If you specify a directory that is not a Git repository, `M-x
magit-status' will offer to initialize it as one.
When `magit-repo-dirs' is not nil, it is treated as a list of
directory names, and `magit-status' will find all Git repositories in
those directories and offer them for completion. (Magit will only look
`magit-repo-dirs-depth' levels deep, however.)
With two prefix arguments, `magit-status' will always prompt for a
raw directory.
Thus, you would normally set `magit-repo-dirs' to the places where
you keep most of your Git repositories and switch between them with
`C-u M-x magit-status'. If you want to go to a repository outside of
your normal working areas, or if you want to create a new repository,
you would use `C-u C-u M-x magit-status'.
You need to explicitly refresh the status buffer when you have made
changes to the repository from outside of Emacs. You can type `g' in
the status buffer itself, or just use `M-x magit-status' instead of
`C-x b' when switching to it. You also need to refresh the status
buffer in this way after saving a file in Emacs.
The header at the top of the status buffer shows a short summary of
the repository state: where it is located, which branch is checked out,
etc. Below the header are a number of sections that show details about
the working tree and the staging area. You can hide and show them as
described in the previous section.
The first section shows _Untracked files_, if there are any. See
*note Untracked files:: for more details.
The next two sections show your local changes. They are explained
fully in the next chapter, *note Staging and Committing::.
If the current branch is associated with a remote tracking branch,
the status buffer shows the differences between the current branch and
the tracking branch. See *note Pushing and Pulling:: for more
information.
During a history rewriting session, the status buffer shows the
_Pending changes_ and _Pending commits_ sections. See *note
Rewriting:: for more details.

File: magit.info, Node: Untracked files, Next: Staging and Committing, Prev: Status, Up: Top
5 Untracked files
*****************
Untracked files are shown in the _Untracked files_ section.
You can add an untracked file to the staging area with `s'. If
point is on the _Untracked files_ section title when you hit `s', all
untracked files are staged.
Typing `C-u S' anywhere will also stage all untracked files,
together with all changes to the tracked files.
You can instruct Git to ignore them by typing `i'. This will add
the filename to the `.gitignore' file. Typing `C-u i' will ask you for
the name of the file to ignore. This is useful to ignore whole
directories, for example. The `I' command is similar to `i' but will
add the file to `.git/info/exclude' instead.
To delete an untracked file forever, use `k'. If point is on the
_Untracked files_ section title when you hit `k', all untracked files
are deleted.

File: magit.info, Node: Staging and Committing, Next: History, Prev: Untracked files, Up: Top
6 Staging and Committing
************************
Comitting with Git is a two step process: first you add the changes you
want to commit to a 'staging area', and then you commit them to the
repository. This allows you to only commit a subset of your local
changes.
Magit allows you to ignore the staging area if you wish. As long as
your staging area is unused, Magit will show your uncomitted changes in
a section named _Changes_.
When the staging area is in use, Magit uses two sections: _Unstaged
changes_ and _Staged changes_. The _Staged changes_ section shows the
changes that will be included in the next commit, while the _Unstaged
changes_ section shows the changes that will be left out.
To move an unstaged hunk into the staging area, move point into the
hunk and type `s'. Likewise, to unstage a hunk, move point into it and
type `u'. If point is in a diff header when you type `s' or `u', all
hunks belonging to that diff are moved at the same time.
If the region is active when you type `s' or `u', only the changes
in the region are staged or unstaged. (This works line by line: if the
beginning of a line is in the region it is included in the changes,
otherwise it is not.)
To change the size of the hunks, you can type `+' or `-' to increase
and decrease, respectively. Typing `0' will reset the hunk size to the
default.
Typing `C-u s' will ask you for a name of a file to be staged, for
example to stage files that are hidden.
To move all hunks of all diffs into the staging area in one go, type
`S'. To unstage everything, type `U'.
Typing `C-u S' will stage all untracked files in addition to the
changes to tracked files.
You can discard uncommitted changes by moving point into a hunk and
typing `k'. The changes to discard are selected as with `s' and `u'.
Before committing, you should write a short description of the
changes.
Type `c' to pop up a buffer where you can write your change
description. Once you are happy with the description, type `C-c C-c'
in that buffer to perform the commit.
If you want to write changes in a `ChangeLog' file, you can use `C-x
4 a' on a diff hunk.
Typing `c' when the staging area is unused is a special situation.
Normally, the next commit would be empty, but you can configure Magit
to do something more useful by customizing the
`magit-commit-all-when-nothing-staged' variable. One choice is to
instruct the subsequent `C-c C-c' to commit all changes. Another
choice is stage everything at the time of hitting `c'.
You can type `C-c C-a' in the buffer with the change description to
toggle a flag that determines whether the next commit will _amend_ the
current commit in HEAD.
Typing `C-c C-s' will toggle the `--signoff' option. The default is
determined by the `magit-commit-signoff' customization variable.
Typing `C-c C-e' will toggle the `--allow-empty' option. This
allows you to make commits that serve as notes, without including any
changes.
Typing `C-c C-t' will toggle the option to specify the name and
email address for the commit's author. The default is determined by
the `user.name' and `user.email' git configuration settings.
If you change your mind and don't want to go ahead with your commit
while you are in the `*magit-log-edit*' buffer, you can just switch to
another buffer, continue editing there, staging and unstaging things
until you are happy, and then return to the `*magit-log-edit*' buffer,
maybe via `C-x b', or by hitting `c' again in a Magit buffer.
If you want to erase the `*magit-log-edit*' buffer and bury it, you
can hit `C-c C-k' in it.
Typing `C' will also pop up the change description buffer, but in
addition, it will try to insert a ChangeLog-style entry for the change
that point is in.

File: magit.info, Node: History, Next: Reflogs, Prev: Staging and Committing, Up: Top
7 History
*********
To show the repository history of your current head, type `l l'. A new
buffer will be shown that displays the history in a terse form. The
first paragraph of each commit message is displayed, next to a
representation of the relationships between commits.
To show the repository history between two branches or between any
two points of the history, type `l r l'. You will be prompted to enter
references for starting point and ending point of the history range; you
can use auto-completion to specify them. A typical use case for ranged
history log display would be `l r l master RET new-feature RET' that
will display commits on the new-feature branch that are not in master;
these commits can then be inspected and cherry-picked, for example.
More thorough filtering can be done by supplying `l' with one or
more suffix arguments, as displayed in its popup. `=g' ('Grep') for
example, limits the output to commits of which the log message matches
a specific string/regex.
Typing `l L' (or `l C-u L') will show the log in a more verbose form.
Magit will show only `magit-log-cutoff-length' entries. `e' will
show twice as many entries. `C-u e' will show all entries, and given a
numeric prefix argument, `e' will add this number of entries.
You can move point to a commit and then cause various things to
happen with it. (The following commands work in any list of commits,
such as the one shown in the _Unpushed commits_ section.)
Typing `RET' will pop up more information about the current commit
and move point into the new buffer. *Note Commit Buffer::. Typing
`SPC' and `DEL' will also show the information, but will scroll the new
buffer up or down (respectively) when typed again.
Typing `a' will apply the current commit to your current branch.
This is useful when you are browsing the history of some other branch
and you want to `cherry-pick' some changes from it. A typical
situation is applying selected bug fixes from the development version
of a program to a release branch. The cherry-picked changes will not
be committed automatically; you need to do that explicitly.
Typing `A' will cherry-pick the current commit and will also commit
the changes automatically when there have not been any conflicts.
Typing `v' will revert the current commit. Thus, it will apply the
changes made by that commit in reverse. This is obviously useful to
cleanly undo changes that turned out to be wrong. As with `a', you
need to commit the changes explicitly.
Typing `C-w' will copy the sha1 of the current commit into the kill
ring.
Typing `=' will show the differences from the current commit to the
"marked" commit.
You can mark the current commit by typing `.'. When the current
commit is already marked, typing `.' will unmark it. To unmark the
marked commit no matter where point is, use `C-u .'.
Some commands, such as `=', will use the current commit and the
marked commit as implicit arguments. Other commands will offer the
marked commit as a default when prompting for their arguments.

File: magit.info, Node: Reflogs, Next: Commit Buffer, Prev: History, Up: Top
8 Reflogs
*********
You can use `l h' and `l H' to browse your _reflog_, the local history
of changes made to your repository heads. Typing `H' will ask for a
head, while `l h' will show the reflog of `HEAD'.
The resulting buffer is just like the buffer produced by `l l' and
`l L' that shows the commit history.

File: magit.info, Node: Commit Buffer, Next: Diffing, Prev: Reflogs, Up: Top
9 Commit Buffer
***************
When you view a commit (perhaps by selecting it in the log buffer,
*note History::), the "commit buffer" is displayed, showing you
information about the commit and letting you interact with it.
By placing your cursor within the diff or hunk and typing `a', you
can apply the same patch to your working copy. This is useful when you
want to copy a change from another branch, but don't necessarily want
to cherry-pick the whole commit.
By typing `v' you can apply the patch in reverse, removing all the
lines that were added and adding all the lines that were removed. This
is a convenient way to remove a change after determining that it
introduced a bug.
If the commit message refers to any other commits in the repository
by their unique hash, the hash will be highlighted and you will be able
to visit the referenced commit either by clicking on it or by moving
your cursor onto it and pressing `RET'.
The commit buffer maintains a history of the commits it has shown.
After visiting a referenced commit you can type `C-c C-b' to get back
to where you came from. To go forward in the history, type `C-c C-f'.
There are also `[back]' and `[forward]' buttons at the bottom of the
buffer.

File: magit.info, Node: Diffing, Next: Tagging, Prev: Commit Buffer, Up: Top
10 Diffing
**********
Magit typically shows diffs in the "unified" format.
In any buffer that shows a diff, you can type `e' anywhere within
the diff to show the two versions of the file in Ediff. If the diff is
of a file in the status buffer that needs to be merged, you will be
able to use Ediff as an interactive merge tool. Otherwise, Ediff will
simply show the two versions of the file.
To show the changes from your working tree to another revision, type
`d'. To show the changes between two arbitrary revisions, type `D'.
You can use `a' within the diff output to apply the changes to your
working tree. As usual when point is in a diff header for a file, all
changes for that file are applied, and when it is in a hunk, only that
hunk is. When the region is active, the applied changes are restricted
to that region.
Typing `v' will apply the selected changes in reverse.

File: magit.info, Node: Tagging, Next: Resetting, Prev: Diffing, Up: Top
11 Tagging
**********
Typing `t t' will make a lighweight tag. Typing `t a' will make an
annotated tag. It will put you in the normal `*magit-log-edit' buffer
for writing commit messages, but typing `C-c C-c' in it will make the
tag instead. This is controlled by the `Tag' field that will be added
to the `*magit-log-edit*' buffer. You can edit it, if you like.

File: magit.info, Node: Resetting, Next: Stashing, Prev: Tagging, Up: Top
12 Resetting
************
Once you have added a commit to your local repository, you can not
change that commit anymore in any way. But you can reset your current
head to an earlier commit and start over.
If you have published your history already, rewriting it in this way
can be confusing and should be avoided. However, rewriting your local
history is fine and it is often cleaner to fix mistakes this way than
by reverting commits (with `v', for example).
Typing `x' will ask for a revision and reset your current head to
it. No changes will be made to your working tree and staging area.
Thus, the _Staged changes_ section in the status buffer will show the
changes that you have removed from your commit history. You can commit
the changes again as if you had just made them, thus rewriting history.
Typing `x' while point is in a line that describes a commit will
offer this commit as the default revision to reset to. Thus, you can
move point to one of the commits in the _Unpushed commits_ section and
hit `x RET' to reset your current head to it.
Type `X' to reset your working tree and staging area to the most
recently committed state. This will discard your local modifications,
so be careful.
You can give a prefix to `x' if you want to reset both the current
head and your working tree to a given commit. This is the same as
first using an unprefixed `x' to reset only the head, and then using
`X'.

File: magit.info, Node: Stashing, Next: Branching, Prev: Resetting, Up: Top
13 Stashing
***********
You can create a new stash with `z z'. Your stashes will be listed in
the status buffer, and you can apply them with `a' and pop them with
`A'. To drop a stash, use `k'.
With a prefix argument, both `a' and `A' will attempt to reinstate
the index as well as the working tree from the stash.
Typing `z -k z' will create a stash just like `z z', but will leave
the changes in your working tree and index. This makes it easier to,
for example, test multiple variations of the same change.
If you just want to make quick snapshots in between edits, you can
use `z s', which automatically enters a timestamp as description, and
keeps your working tree and index intact by default.
You can visit and show stashes in the usual way: Typing `SPC' and
`DEL' will pop up a buffer with the description of the stash and scroll
it, typing `RET' will move point into that buffer. Using `C-u RET' will
move point into that buffer in other window.

File: magit.info, Node: Branching, Next: The Branch Manager, Prev: Stashing, Up: Top
14 Branching
************
The current branch is indicated in the header of the status buffer.
You can switch to a different branch by typing `b b'. This will
immediately checkout the branch into your working copy, so you
shouldn't have any local modifications when switching branches.
If you try to switch to a remote branch, Magit will offer to create a
local tracking branch for it instead. This way, you can easily start
working on new branches that have appeared in a remote repository.
Typing `b b' while point is at a commit description will offer that
commit as the default to switch to. This will result in a detached
head.
Typing `b m' will let you rename a branch. Unless a branch with the
same name already exists, obviously...
To create a new branch and switch to it immediately, type `b n'.
To delete a branch, type `b d'. If you're currently on that branch,
Magit will offer to switch to the 'master' branch.
Deleting a branch is only possible if it's already fully merged into
HEAD or its upstream branch. Unless you type `b D', that is. Here be
dragons...
Typing `b v' will list the local and remote branches in a new buffer
called `*magit-branches*' from which you can work with them. See *note
The Branch Manager:: for more details.

File: magit.info, Node: The Branch Manager, Next: Wazzup, Prev: Branching, Up: Top
15 The Branch Manager
*********************
The Branch Manager is a separate buffer called `*magit-branches*' with
its own local key map. The buffer contains both local and remote
branches. The current local branch is marked by a "*" in front of the
name.
To check out a branch, move your cursor to the desired branch and
press `RET'.
Typing `k' will delete the branch in the current line, and `C-u k'
deletes it even if it hasn't been merged into the current local branch.
Deleting works for both local and remote branches.
By typing `T' on a local branch, you can change which remote branch
it's set to track.

File: magit.info, Node: Wazzup, Next: Merging, Prev: The Branch Manager, Up: Top
16 Wazzup
*********
Typing `w' will show a summary of how your other branches relate to the
current branch.
For each branch, you will get a section that lists the commits in
that branch that are not in the current branch. The sections are
initially collapsed; you need to explicitly open them with `TAB' (or
similar) to show the lists of commits.
When point is on a _N unmerged commits in ..._ title, the
corresponding branch will be offered as the default for a merge.
Hitting `i' on a branch title will ignore this branch in the wazzup
view. You can use `C-u w' to show all branches, including the ignored
ones. Hitting `i' on an already ignored branch in that view will
unignore it.

File: magit.info, Node: Merging, Next: Rebasing, Prev: Wazzup, Up: Top
17 Merging
**********
Magit offers two ways to merge branches: manual and automatic. A
manual merge will apply all changes to your working tree and staging
area, but will not commit them, while an automatic merge will go ahead
and commit them immediately.
Type `m m' to initiate merge.
After initiating a merge, the header of the status buffer might
remind you that the next commit will be a merge commit (with more than
one parent). If you want to abort a manual merge, just do a hard reset
to HEAD with `X'.
Merges can fail if the two branches you want to merge introduce
conflicting changes. In that case, the automatic merge stops before the
commit, essentially falling back to a manual merge. You need to resolve
the conflicts for example with `e' and stage the resolved files, for
example with `S'.
You can not stage individual hunks one by one as you resolve them,
you can only stage whole files once all conflicts in them have been
resolved.

File: magit.info, Node: Rebasing, Next: Rewriting, Prev: Merging, Up: Top
18 Rebasing
***********
Typing `R' in the status buffer will initiate a rebase or, if one is
already in progress, ask you how to continue.
When a rebase is stopped in the middle because of a conflict, the
header of the status buffer will indicate how far along you are in the
series of commits that are being replayed. When that happens, you
should resolve the conflicts and stage everything and hit `R c' to
continue the rebase. Alternatively, hitting `c' or `C' while in the
middle of a rebase will also ask you whether to continue the rebase.
Of course, you can initiate a rebase in any number of ways, by
configuring `git pull' to rebase instead of merge, for example. Such a
rebase can be finished with `R' as well.

File: magit.info, Node: Rewriting, Next: Pushing and Pulling, Prev: Rebasing, Up: Top
19 Rewriting
************
As hinted at earlier, you can rewrite your commit history. For
example, you can reset the current head to an earlier commit with `x'.
This leaves the working tree unchanged, and the status buffer will show
all the changes that have been made since that new value of the current
head. You can commit these changes again, possibly splitting them into
multiple commits as you go along.
Amending your last commit is a common special case of rewriting
history like this.
Another common way to rewrite history is to reset the head to an
earlier commit, and then to cherry pick the previous commits in a
different order. You could pick them from the reflog, for example.
Magit has several commands that can simplify the book keeping
associated with rewriting. These commands all start with the `r'
prefix key.
Typing `r b' will start a rewrite operation. You will be prompted
for a _base_ commit. This commit and all subsequent commits up until
the current head are then put in a list of _Pending commits_, after
which the current head will be reset to the _parent_ of the base
commit. This can be configured to behave like `git rebase', i.e.
exclude the selected base commit from the rewrite operation, with the
`magit-rewrite-inclusive' variable.
You would then typically use `a' and `A' to cherry pick commits from
the list of pending commits in the desired order, until all have been
applied. Magit shows which commits have been applied by changing their
marker from `*' to `.'.
Using `A' will immediately commit the commit (as usual). If you
want to combine multiple previous commits into a single new one, use
`a' to apply them all to your working tree, and then commit them
together.
Magit has no explicit support for rewriting merge commits. It will
happily include merge commits in the list of pending commits, but there
is no way of replaying them automatically. You have to redo the merge
explicitly.
You can also use `v' to revert a commit when you have changed your
mind. This will change the `.' mark back to `*'.
Once you are done with the rewrite, type `r s' to remove the book
keeping information from the status buffer.
If you rather wish to start over, type `r a'. This will abort the
rewriting, resetting the current head back to the value it had before
the rewrite was started with `r s'.
Typing `r f' will _finish_ the rewrite: it will apply all unused
commits one after the other, as if you would us `A' with all of them.
You can change the `*' and `.' marks of a pending commit explicitly
with `r *' and `r .'.
In addition to a list of pending commits, the status buffer will show
the _Pending changes_. This section shows the diff between the
original head and the current head. You can use it to review the
changes that you still need to rewrite, and you can apply hunks from
it, like from any other diff.

20 Pushing and Pulling
**********************
Magit will run `git push' when you type `P P'. If you give a prefix
argument to `P P', you will be prompted for the repository to push to.
When no default remote repository has been configured yet for the
current branch, you will be prompted as well. Typing `P P' will only
push the current branch to the remote. In other words, it will run
`git push <remote> <branch>'. The branch will be created in the remote
if it doesn't exist already. The local branch will be configured so
that it pulls from the new remote branch. If you give a double prefix
argument to `P P', you will be prompted in addition for the target
branch to push to. In other words, it will run `git push <remote>
<branch>:<target>'.
Typing `f f' will run `git fetch'. It will prompt for the name of
the remote to update if there is no default one. Typing `f o' will
always prompt for the remote. Typing `F F' will run `git pull'. When
you don't have a default branch configured to be pulled into the
current one, you will be asked for it.
If there is a default remote repository for the current branch, Magit
will show that repository in the status buffer header.
In this case, the status buffer will also have a _Unpushed commits_
section that shows the commits on your current head that are not in the
branch named `<remote>/<branch>'. This section works just like the
history buffer: you can see details about a commit with `RET', compare
two of them with `.' and `=', and you can reset your current head to
one of them with `x', for example. If you want to push the changes then
type `P P'.
When the remote branch has changes that are not in the current
branch, Magit shows them in a section called _Unpulled changes_. Typing
`F F' will fetch and merge them into the current branch.

22 Bisecting
************
Magit supports bisecting by showing how many revisions and steps are
left to be tested in the status buffer. You can control the bisect
session from both the status and from log buffers with the `B' key menu.
Typing `B s' will start a bisect session. You will be prompted for
a revision that is known to be bad (defaults to _HEAD_) and for a
revision that is known to be good (defaults to the revision at point if
there is one). git will select a revision for you to test, and Magit
will update its status buffer accordingly.
You can tell git that the current revision is good with `B g', that
it is bad with `B b' or that git should skip it with `B k'. You can
also tell git to go into full automatic mode by giving it the name of a
script to run for each revision to test with `B u'.
The current status can be shown as a log with `B l'. It contains the
revisions that have already been tested and your decisions about their
state.
The revisions left to test can be visualized in gitk with `B v'.
When you're finished bisecting you have to reset the session with `B
r'.

File: magit.info, Node: Activating extensions, Next: Interfacing with Subversion, Up: Using Magit Extensions
23.1 Activating extensions
==========================
Magit comes with a couple of shipped extensions that allow interaction
with `git-svn', `topgit' and `stgit'. See following sections for
specific details on how to use them.
Extensions can be activated globally or on a per-repository basis.
Since those extensions are implemented as minor modes, one can use for
example `M-x magit-topgit-mode' to toggle the `topgit' extension,
making the corresponding section and commands (un)available.
In order to do that automatically (and for every repository), one can
use for example:
(add-hook 'magit-mode-hook 'turn-on-magit-topgit)
Magit also allows configuring different extensions, based on the git
repository configuration.
(add-hook 'magit-mode-hook 'magit-load-config-extensions)
This will read git configuration variables and activate the relevant
extensions.
For example, after running the following commands, the `topgit'
extension will be loaded for every repository, while the `svn' one will
be loaded only for the current one.
$ git config --global --add magit.extension topgit
$ git config --add magit.extension svn
Note the `--add' flag, which means that each extension gets its own
line in the `config' file.

File: magit.info, Node: Interfacing with Subversion, Next: Interfacing with Topgit, Prev: Activating extensions, Up: Using Magit Extensions
23.2 Interfacing with Subversion
================================
Typing `N r' runs `git svn rebase', typing `N c' runs `git svn dcommit'
and typing `N f' runs `git svn fetch'.
`N s' will prompt you for a (numeric, Subversion) revision and then
search for a corresponding Git sha1 for the commit. This is limited to
the path of the remote Subversion repository. With a prefix (`C-u N s'
the user will also be prompted for a branch to search in.

File: magit.info, Node: Interfacing with Topgit, Next: Interfacing with StGit, Prev: Interfacing with Subversion, Up: Using Magit Extensions
23.3 Interfacing with Topgit
============================
Topgit (http://repo.or.cz/r/topgit.git) is a patch queue manager that
aims at being close as possible to raw Git, which makes it easy to use
with Magit. In particular, it does not require to use a different set of
commands for "commit", "update",… operations.
`magit-topgit.el' provides basic integration with Magit, mostly by
providing a "Topics" section.
Topgit branches can be created the regular way, by using a "t/"
prefix by convention. So, creating a "t/foo" branch will actually
populate the "Topics" section with one more branch after committing
`.topdeps' and `.topmsg'.
Also, the way we pull (see *note Pushing and Pulling::) such a
branch is slightly different, since it requires updating the various
dependencies of that branch. This should be mostly transparent, except
in case of conflicts.

File: magit.info, Node: Interfacing with StGit, Next: Developing Extensions, Prev: Interfacing with Topgit, Up: Using Magit Extensions
23.4 Interfacing with StGit
===========================
StGit (http://www.procode.org/stgit) is a Python application providing
similar functionality to Quilt (i.e. pushing/popping patches to/from a
stack) on top of Git. These operations are performed using Git commands
and the patches are stored as Git commit objects, allowing easy merging
of the StGit patches into other repositories using standard Git
functionality.
`magit-stgit.el' provides basic integration with Magit, mostly by
providing a "Series" section, whose patches can be seen as regular
commits through the "visit" action.
You can change the current patch in a series with the "apply" action,
as well as you can delete them using the "discard" action.
Additionally, the `magit-stgit-refresh' and `magit-stgit-rebase'
commands let you perform the respective StGit operations.

File: magit.info, Node: Developing Extensions, Prev: Interfacing with StGit, Up: Using Magit Extensions
23.5 Developing Extensions
==========================
Magit provides a generic mechanism to allow cooperation with Git-related
systems, such as foreign VCS, patch systems,…
In particular it allows to:
* Define sections to display specific informations about the current
state of the repository, and place them relatively to existing
sections.
`magit-define-inserter' automagically defines two hooks called
`magit-before-insert-SECTION-hook' and
`magit-after-insert-SECTION-hook' that allow to generate and place
more sections.
In the following example, we use the builtin "stashes" section to
place our own "foo" one.
(magit-define-inserter foo ()
(magit-git-section 'foo
"Foo:" 'foo-wash-function
"foo" "arg1" "arg2"))
(add-hook 'magit-after-insert-stashes-hook 'magit-insert-foo)
* Define new types of objects in those sections.
The function `foo-wash-function' defined above post-processes each
line of the output of the "git foo arg1 arg2" command, and is able
to associate a type to certain lines.
A simple implementation could be:
(defun foo-wash-function ()
(let ((foo (buffer-substring (line-beginning-position) (line-end-position))))
(goto-char (line-beginning-position))
(magit-with-section foo 'foo
(magit-set-section-info foo)
(forward-line))))
In this case, every line of the command output is transformed into
an object of type `'foo'.
* Alter behavior of generic commands to dispatch them correctly to
the relevant system, optionally making use of the newly defined
types.
(magit-add-action (item info "discard")
((foo)
(do-something-meaningful-for-discarding-a-foo)))
This will alter the behavior of `k', when applied to those objects.
* Plug a different logic into basic commands, to reflect the
presence of the extension.
`magit-define-command' automagically defines a
`magit-CMD-command-hook' that can contain a list of functions to
call before the actual core code. Execution stops after the first
hook that returns a non-nil value. This leaves room for extension
logic.
(add-hook 'magit-create-branch-command-hook 'foo-create-branch)
The function `foo-create-branch' will be called each time an
attempt is made to create a branch, and can, for example, react to
a certain name convention.
* Define new commands and associated menu.
This part is not really specific to extensions, except that menus
take place in the "Extensions" submenu.
It is suggested that Magit extensions authors stick to the
convention of making extensions minor modes. This has many advantages,
including the fact that users are able to toggle extensions, and that
it's easy to configure a specific set of extensions for a given
repository.
Shipped extensions can serve as an example of how to develop new
extensions.
Basically a `foo' extension should provide a `magit-foo-mode' minor
mode, as well as a `turn-on-magit-foo' function. The main task of the
minor mode is to register/unregister the various hooks that the
extension requires. The registered actions on the other hand can be
left alone and activated globally, since they can be run only on
displayed items, which won't happen when the minor mode is off.
Don't forget to call `magit-refresh' when the minor mode is toggled
interactively, so that the relevant sections can be shown or hidden.

24 Using Git Directly
*********************
For situations when Magit doesn't do everything you need, you can run
raw Git commands using `:'. This will prompt for a Git command, run
it, and refresh the status buffer. The output can be viewed by typing
`$'.

File: magit.info, Node: Customization, Next: Frequently Asked Questions, Prev: Using Git Directly, Up: Top
25 Customization
****************
The following variables can be used to adapt Magit to your workflow:
`magit-git-executable'
The name of the Git executable.
`magit-git-standard-options'
Standard options when running Git.
`magit-repo-dirs'
Directories containing Git repositories.
Magit will look into these directories for Git repositories and
offer them as choices for `magit-status'.
`magit-repo-dirs-depth'
The maximum depth to look for Git repos.
When looking for a Git repository below the directories in
`magit-repo-dirs', Magit will only descend this many levels deep.
`magit-save-some-buffers'
Non-nil means that `magit-status' will save modified buffers
before running. Setting this to `t' will ask which buffers to
save, setting it to `'dontask' will save all modified buffers
without asking.
`magit-save-some-buffers-predicate'
Specifies a predicate function on `magit-save-some-buffers' to
determine which unsaved buffers should be prompted for saving.
`magit-commit-all-when-nothing-staged'
Determines what `magit-log-edit' does when nothing is staged.
Setting this to `nil' will make it do nothing, setting it to `t'
will arrange things so that the actual commit command will use the
`--all' option, setting it to `'ask' will first ask for
confirmation whether to do this, and setting it to `'ask-stage'
will cause all changes to be staged, after a confirmation.
`magit-commit-signoff'
When performing `git commit' adds `--signoff'.
`magit-log-cutoff-length'
The maximum number of commits to show in the `log' and `whazzup'
buffers.
`magit-log-infinite-length'
Number of log used to show as maximum for
`magit-log-cutoff-length'.
`magit-log-auto-more'
Insert more log entries automatically when moving past the last
entry.
Only considered when moving past the last entry with
`magit-goto-next-section'.
`magit-process-popup-time'
Popup the process buffer if a command takes longer than this many
seconds.
`magit-revert-item-confirm'
Require acknowledgment before reverting an item.
`magit-log-edit-confirm-cancellation'
Require acknowledgment before canceling the log edit buffer.
`magit-remote-ref-format'
What format to use for autocompleting refs, in pariticular for
remotes.
Autocompletion is used by functions like `magit-checkout',
`magit-interactive-rebase' and others which offer branch name
completion.
The value `'name-then-remote' means remotes will be of the form
`name (remote)', while the value `'remote-slash-name' means that
they'll be of the form `remote/name'. I.e. something that's listed
as `remotes/upstream/next' by `git branch -l -a' will be
`upstream/next'.
`magit-process-connection-type'
Connection type used for the git process.
`nil' mean pipe, it is usually faster and more efficient, and work
on cygwin. `t' mean pty, it enable magit to prompt for passphrase
when needed.
`magit-completing-read-function'
Function to be called when requesting input from the user.
`magit-create-branch-behaviour'
Where magit will create a new branch if not supplied a branchname
or ref.
The value `'at-head' means a new branch will be created at the tip
of your current branch, while the value `'at-point' means magit
will try to find a valid reference at point...
`magit-status-buffer-switch-function'
Function for `magit-status' to use for switching to the status
buffer.
The function is given one argument, the status buffer.
`magit-rewrite-inclusive'
Whether magit includes the selected base commit in a rewrite
operation.
`t' means both the selected commit as well as any subsequent
commits will be rewritten. This is magit's default behaviour,
equivalent to `git rebase -i ${REV~1}'
A'---B'---C'---D'
^
`nil' means the selected commit will be literally used as `base',
so only subsequent commits will be rewritten. This is consistent
with git-rebase, equivalent to `git rebase -i ${REV}', yet more
cumbersome to use from the status buffer.
A---B'---C'---D'
^
`magit-topgit-executable'
The name of the TopGit executable.
`magit-topgit-branch-prefix'
Convention prefix for topic branch creation.

26.3.1 Question 2.1
-------------------
How do I fix international characters display?
Answer
......
Please make sure your Magit buffer uses a compatible coding system. In
the particular case of file names, git itself quotes them by default.
You can disable this with one of the following approaches:
$ git config core.quotepath false
or
(setq magit-git-standard-options (append magit-git-standard-options
'("-c" "core.quotepath=false")))
The latter might not work in old versions of git.
