 # fugitive.vim
 
-I'm not going to lie to you; fugitive.vim may very well be the best
-Git wrapper of all time.  Check out these features:
+Fugitive is the premier Vim plugin for Git.  Or maybe it's the premier Git
+plugin for Vim?  Either way, it's "so awesome, it should be illegal".  That's
+why it's called Fugitive.
 
-Bring up an enhanced version of `git status` with `:G` (also known as
-`:Gstatus`).  Press `g?` to bring up a list of maps for numerous operations
-including diffing, staging, committing, rebasing, and stashing.
+The crown jewel of Fugitive is `:Git` (or just `:G`), which calls any
+arbitrary Git command.  If you know how to use Git at the command line, you
+know how to use `:Git`.  It's vaguely akin to `:!git` but with numerous
+improvements:
 
-View any blob, tree, commit, or tag in the repository with `:Gedit` (and
-`:Gsplit`, `:Gvsplit`, `:Gtabedit`, ...).  Edit a file in the index and
-write to it to stage the changes.  Use `:Gdiffsplit` to bring up the staged
-version of the file side by side with the working tree version and use
-Vim's diff handling capabilities to stage a subset of the file's
-changes.
+* The default behavior is to directly echo the command's output.  Quiet
+  commands like `:Git add` avoid the dreaded "Press ENTER or type command to
+  continue" prompt.
+* `:Git commit`, `:Git rebase -i`, and other commands that invoke an editor do
+  their editing in the current Vim instance.
+* `:Git diff`, `:Git log`, and other verbose, paginated commands have their
+  output loaded into a temporary buffer.  Force this behavior for any command
+  with `:Git --paginate` or `:Git -p`.
+* `:Git blame` uses a temporary buffer with maps for additional triage.  Press
+  enter on a line to view the commit where the line changed, or `g?` to see
+  other available maps.  Omit the filename argument and the currently edited
+  file will be blamed in a vertical, scroll-bound split.
+* `:Git mergetool` and `:Git difftool` load their changesets into the quickfix
+  list.
+* Called with no arguments, `:Git` opens a summary window with dirty files and
+  unpushed and unpulled commits.  Press `g?` to bring up a list of maps for
+  numerous operations including diffing, staging, committing, rebasing, and
+  stashing.  (This is the successor to the old `:Gstatus`.)
+* This command (along with all other commands) always uses the current
+  buffer's repository, so you don't need to worry about the current working
+  directory.
 
-Commit, merge, and rebase with `:Gcommit`, `:Gmerge`, and `:Grebase`, using
-the current Vim instance to edit commit messages and the rebase todo list.
-Use `:Gpush`, `:Gfetch`, and `:Gpull` to send and retrieve upstream changes.
+Additional commands are provided for higher level operations:
 
-`:Gblame` brings up an interactive vertical split with `git blame`
-output.  Press enter on a line to edit the commit where the line
-changed, or `o` to open it in a split.  When you're done, use `:Gedit`
-in the historic buffer to go back to the work tree version.
-
-`:Gmove` does a `git mv` on a file and simultaneously renames the
-buffer.  `:Gdelete` does a `git rm` on a file and simultaneously deletes
-the buffer.
-
-Use `:Ggrep` to search the work tree (or any arbitrary commit) with
-`git grep`, skipping over that which is not tracked in the repository.
-`:Gclog` and `:Gllog` load all previous commits into the quickfix or location
-list.  Give them a range (e.g., using visual mode and `:'<,'>Gclog`) to
-iterate over every change to that portion of the current file.
-
-`:Git mergetool` loads conflicts into the quickfix list.  `:Git difftool` does
-the same for any arbitrary set of changes.
-
-`:Gread` is a variant of `git checkout -- filename` that operates on the
-buffer rather than the filename.  This means you can use `u` to undo it
-and you never get any warnings about the file changing outside Vim.
-`:Gwrite` writes to both the work tree and index versions of a file,
-making it like `git add` when called from a work tree file and like
-`git checkout` when called from the index or a blob in history.
-
-Use `:Gbrowse` to open the current file on the web front-end of your favorite
-hosting provider, with optional line range (try it in visual mode).  Plugins
-are available for popular providers such as [GitHub][rhubarb.vim],
-[GitLab][fugitive-gitlab.vim], [Bitbucket][fubitive.vim],
-[Gitee][fugitive-gitee.vim], [Pagure][pagure], and
-[Phabricator][vim-phabricator].
+* View any blob, tree, commit, or tag in the repository with `:Gedit` (and
+  `:Gsplit`, etc.).  For example, `:Gedit HEAD~3:%` loads the current file as
+  it existed 3 commits ago.
+* `:Gdiffsplit` (or `:Gvdiffsplit`) brings up the staged version of the file
+  side by side with the working tree version.  Use Vim's diff handling
+  capabilities to apply changes to the staged version, and write that buffer
+  to stage the changes.  You can also give an arbitrary `:Gedit` argument to
+  diff against older versions of the file.
+* `:Gread` is a variant of `git checkout -- filename` that operates on the
+  buffer rather than the file itself.  This means you can use `u` to undo it
+  and you never get any warnings about the file changing outside Vim.
+* `:Gwrite` writes to both the work tree and index versions of a file, making
+  it like `git add` when called from a work tree file and like `git checkout`
+  when called from the index or a blob in history.
+* `:Ggrep` is `:grep` for `git grep`.  `:Glgrep` is `:lgrep` for the same.
+* `:GMove` does a `git mv` on the current file and changes the buffer name to
+  match.  `:GRename` does the same with a destination filename relative to the
+  current file's directory.
+* `:GDelete` does a `git rm` on the current file and simultaneously deletes
+  the buffer.  `:GRemove` does the same but leaves the (now empty) buffer
+  open.
+* `:GBrowse` to open the current file on the web front-end of your favorite
+  hosting provider, with optional line range (try it in visual mode).  Plugins

 ## FAQ
 
-> Why can't I enter my password when I `:Gpush`?
+> What happened to the dispatch.vim backed asynchronous `:Gpush` and
+> `:Gfetch`?
 
-It is highly recommended to use SSH keys or [credentials caching][] to avoid
-entering your password on every upstream interaction.  If this isn't an
-option, the official solution is to use the `core.askPass` Git option to
-request the password via a GUI.  Fugitive will configure this for you
-automatically if you have `ssh-askpass` or `git-gui` installed; otherwise it's
-your responsibility to set this up.
+This behavior was divisive, confusing, and complicated inputting passwords, so
+it was removed.  Use `:Git! push` to use Fugitive's own asynchronous
+execution, or retroactively make `:Git push` asynchronous by pressing
+`CTRL-D`.
 
-If you absolutely must type in your password by hand, sidestep Fugitive and
-use `:terminal git push`.
+> Why am I getting `core.worktree is required when using an external Git dir`?
 
-[credentials caching]: https://help.github.com/en/articles/caching-your-github-password-in-git
+Git generally sets `core.worktree` for you automatically when necessary, but
+if you're doing something weird, or using a third-party tool that does
+something weird, you may need to set it manually:
+
+    git config core.worktree "$PWD"
+
+This may be necessary even when simple `git` commands seem to work fine
+without it.
+
+> So I have a symlink and...
+
+Stop.  Just stop.  If Git won't deal with your symlink, then Fugitive won't
+either.  Consider using a [plugin that resolves
+symlinks](https://github.com/aymericbeaumet/symlink.vim), or even better,
+using fewer symlinks.

+Fugitive used to support `:autocmd User Fugitive` to run an autocommand after
+loading any buffer belonging to a Git repository, but this is being phased
+out.  Instead, one can leverage regular autocommand events like |BufNewFile|
+and |BufReadPost|, and check !empty(FugitiveGitDir()) to confirm Fugitive has
+found a repository.  See also |fugitive-autocommands| for other, more
+selective events.
