;;; Introduction
|
|
|
|
;; Invoking the magit-status function will show a buffer with the
|
|
;; current status of the current git repository and its checkout.
|
|
;; That buffer offers key bindings for manipulating the status in
|
|
;; simple ways.
|
|
;;
|
|
;; The status buffer mainly shows the difference between the working
|
|
;; tree and the index, and the difference between the index and the
|
|
;; current HEAD. You can add individual hunks from the working tree
|
|
;; to the index, and you can commit the index.
|
|
|
|
;;; TODO
|
|
|
|
;; - Diffing between branches
|
|
;; - Polish history browsing. Scroll when leaning on RET, etc.
|
|
;; - Indicate active command in modeline. Show progress in message area?
|
|
;; - Detect and handle renames and copies.

\\<magit-mode-map>
|
|
The buffer shows your changes (in the form of 'diff hunks') on
|
|
their way into the local and remote repository. Normally, you
|
|
collect a set of changes into the staging area that you want to
|
|
commit as a unit, and then you commit them.
|
|
|
|
Typing `\\[magit-stage-thing-at-point]' will move the diff hunk
|
|
that point is in into the staging area. Typing
|
|
`\\[magit-unstage-thing-at-point]' will remove it from the staging
|
|
area. When point is on a diff header for a file when you type
|
|
`\\[magit-stage-thing-at-point]' or
|
|
`\\[magit-unstage-thing-at-point]', all changes belonging to the
|
|
file will move together. You can also type `\\[magit-stage-all]'
|
|
to stage all unstaged changes in one go.
|
|
|
|
To commit the staged changes, type `\\[magit-log-edit]'. A
|
|
buffer will pop up where you can describe the changes. Typing
|
|
`C-c C-c' in that buffer will peform the commit. The content of
|
|
that buffer is preserved until you finally do commit it, so you
|
|
can go back and forth between your source files, the status
|
|
buffer, and the commit message buffer until you are ready to
|
|
commit.
|
|
|
|
The status buffer also lists untracked files; you should either
|
|
start tracking them by typing `\\[magit-stage-thing-at-point]' when
|
|
point is on one of them, or tell git to ignore them by typing
|
|
`\\[magit-ignore-thing-at-point]'.
|
|
|
|
If you make changes to your git status outside of Emacs, type
|
|
`\\[magit-status]' to refresh the status buffer. You also need
|
|
to do this after saving one or more files. For performance
|
|
reasons, the status buffer is not updated every time you save.
|
|
Instead, you should run `magit-status' whenever you want to look
|
|
at the status buffer. Of course, you can bind `magit-status' to
|
|
a key to make this convenient.
|
|
|
|
If you want to remove or rename tracked files, use \"git rm\" or
|
|
\"git mv\" directly (and then refresh the status buffer to see
|
|
the changes).
|
|
|
|
Type `\\[magit-switch-branch]' to switch to another branch. To
|
|
create a new branch, type `\\[magit-create-branch]'.
|
|
|
|
There are two commands for merging a branch into the current
|
|
branch. Type `\\[magit-manual-merge]' to initiate a `manual'
|
|
merge: the changes resulting from the merge will not be
|
|
committed, even when there are no conflicts. You can review them
|
|
and make modifications until you are ready to commit them.
|
|
Typing `\\[magit-automatic-merge]' will initiate a `automatic'
|
|
merge which will automatically commit the merged changes when
|
|
there are no conflicts.
|
|
|
|
While a merge is ongoing (i.e., until the merge commit has been
|
|
added to the repository), the status buffer shows the branches
|
|
that are being merged at the top.
|
|
|
|
You can `soft reset' your repository by typing
|
|
`\\[magit-reset-soft]'. The current head will be set to the
|
|
commit that you specify, but your working tree and the staging
|
|
area are not changed. Typing `\\[magit-reset-hard]' will do a
|
|
`hard reset': all of the current head, your working tree, and the
|
|
the index will be reverted to the commit that you specify. Doing
|
|
a hard reset without actually changing the current head will thus
|
|
throw away all your uncommitted changes. You can do this to
|
|
abort a merge, for example.
|
|
|
|
When you have a remote repository configured for the current
|
|
branch (such as when \"git clone\" has done this for you
|
|
automatically), it is shown at the top of the status buffer. You
|
|
can type `\\[magit-pull]' to run \"git pull\" and
|
|
`\\[magit-push]' to run \"git push\". Typing
|
|
`\\[magit-display-process]' will pop up a buffer with a
|
|
transcript of these commands. There is also a section at the
|
|
bottom that gives a summary of the changes that you have not yet
|
|
pushed.
