** Tips
*** Start helm-ls-git
You can start with `helm-ls-git' but you can also use the generic
`helm-browse-project' which will use `helm-ls-git' if you are in
a git project (actually supported backends are git and hg though
helm-ls-hg is no more maintained).
Using the browse project action from `helm-find-files' allow
you to switch to another project easily (\\<helm-find-files-map>\\[helm-ff-run-browse-project]) .
See also the command `helm-projects-history' bound to
\\[helm-projects-history] to switch to one project to the other.
Also using bookmarks to switch projects is a good alternative.
*** Git status command
By default `helm-ls-git-status-command' is nil,
but you can set it if needed to `magit-status', `vc-dir' or whatever.
However helm-ls-git provides most of what you need to basically
manage your git repo so you may not need to use another tool,
here an overview of its features:
- Status of modified files
- List project branches
- List project files
- List project buffers
- List of Stashs
- Git log for each branches
- Create a new branch from current one
- Commit your changes from status source
- Rebase interactively
- Amend
- Diffs
- Pull and fetch
- Push
- Stash
- Revert
- Reset
- Format patches
- Git AM
- Cherry pick
etc...
Of course all these features are not enhanced as what you could
find in a Git specialized tool like Magit but it may fit most of
your needs.
*** Git branches
From this source you can see all locals branches and switch to them as needed.
The current branch is prefixed with a star.
You can toggle branches view (locales and remotes) with \\<helm-ls-git-branches-map>\\[helm-ls-git-branches-toggle-show-all].
See the action menu to see other available actions.
*** Git log
From branches source, you can launch git log. With a numeric
prefix arg specify the number of commits to show, once you are in
git log and you want more commits, use a numeric prefix arg with
\\<helm-map>\\[helm-refresh] to specify the number of commits to show.
When scrolling down with an empty pattern, helm can increase
automatically the number of candidates displayed when you reach
end of buffer if `helm-ls-git-auto-refresh-at-eob' is non nil.
NOTE: When searching in git log, Helm search in the candidates
computed initially, this mean that when you have 100 candidates
displayed (see `helm-ls-git-log-max-commits') and you search for
a commit containing \"foo\", this commit will not be found if it
is located in the 101 commit which is not displayed. So if you
don't find something you are looking for, increase the number of
commits with \\<global-map>\\[universal-argument] <n> \\<helm-map>\\[helm-refresh].
**** Specify a range of commits
Once you are in Git log you can specify with 2 marked
candidates a range of commits, specifying more than two marked
candidate for actions accepting only ranges will fail. When
specifying a range of commits, the top commit will be included in
range whereas the bottom commit will not be included, e.g. if you
mark commit-2 and commit-5, and use the format-patch action, git
will make 01-commit-4.patch, 02-commit-3.patch, and
03-commit-2.patch files taking care of naming files in the
reverse order for applying patches later, commit-5 beeing
excluded.
NOTE: For commodity, commits are specified as short hash for all actions, witch
may clash if more than one commit have the same short ID (rare
but may happen), you should have an error in such case.
**** Apply patches from one branch to current
You can apply patches from one branch to current
branch using git AM action.
Patches are specified as a range of commits, see [[Specify a range of commits][Specify a range of commits]].
**** Persistent action in git log
Persistent action in git log shows diff of selected commit, if you
want to always show diff while moving from one commit to the
other use follow-mode (C-c C-f).
*** Git commit
Commits will be done using emacsclient as GIT_EDITOR, with
major-mode `helm-ls-git-commmit-mode' which provide following commands:
\\<helm-ls-git-commit-mode-map>
|Keys|Description
|-------------+--------------|
|\\[helm-ls-git-server-edit]|Exit when done
|\\[helm-ls-git-server-edit-abort]|Abort
If you want to specify another author, use a prefix arg when
calling commit action, you will be prompted for author name and
email.
NOTE: This mode is based on diff-mode, this to show a colorized
diff of your commit, you can use any regular emacs editing
commands from there.
*** Git rebase
helm-ls-git provide two rebase actions, one that run
interactively from git log source and one that work
non-interactively from branches source. With the former you can
rebase interactively from a given commit you selected from git log
and this ONLY for current branch, once done you can rebase one
branch into the other from branches source. This is one workflow
that helm-ls-git provide, other workflows may not work, so for
more complex usage switch to command line or a more enhaced tool
like Magit. For editing the first file git rebase use for
rebasing (\"git-rebase-todo\") helm-ls-git use a major-mode
called `helm-ls-git-rebase-todo-mode' which provide several commands:
\\<helm-ls-git-rebase-todo-mode-map>
|Keys|Description
|-------------+--------------|
|p|pick
|r|reword
|e|edit
|s|squash
|f|fixup
|x|exec
|d|drop
|\\[helm-ls-git-rebase-todo-move-down]|Move line down
|\\[helm-ls-git-rebase-todo-move-up]|Move line up
|\\[helm-ls-git-server-edit]|Exit when done
|\\[helm-ls-git-server-edit-abort]|Abort
*** Git grep usage
The behavior is not exactly the same as what you have when you
launch git-grep from `helm-find-files', here in what it differ:
1) The prefix arg allow to grep only the `default-directory' whereas
with `helm-find-files' the prefix arg allow browsing the whole repo.
So with `helm-ls-git' the default is to grep the whole repo.
2) With `helm-ls-git', because you have the whole list of files of the repo
you can mark some of the files to grep only those, if no files are marked grep
the whole repo or the files under current directory depending of prefix arg.
NOTE: The previous behavior was prompting user for the file
extensions to grep, this is non sense because we have here the
whole list of files (recursive) of current repo and not only the
file under current directory, so we have better time
selectionning the files we want to grep.
**** Grep a subdirectory of current repository.
Switch to `helm-find-files' with `C-x C-f', navigate to your directory
and launch git-grep from there.
*** Problem with unicode filenames (chinese etc...)
See docstring of `helm-ls-git-ls-switches'.
