1. Intro *GundoIntro*
|
||||||
|
|
||||||
|
You know that Vim lets you undo changes like any text editor. What you might
|
||||||
|
not know is that it doesn't just keep a list of your changes -- it keeps
|
||||||
|
a goddamed |:undo-tree| of them.
|
||||||
|
|
||||||
|
Say you make a change (call it X), undo that change, and then make another
|
||||||
|
change (call it Y). With most editors, change X is now gone forever. With Vim
|
||||||
|
you can get it back.
|
||||||
|
|
||||||
|
The problem is that trying to do this in the real world is painful. Vim gives
|
||||||
|
you an |:undolist| command that shows you the leaves of the tree. Good luck
|
||||||
|
finding the change you want in that list.
|
||||||
|
|
||||||
|
Gundo is a plugin to make browsing this ridiculously powerful undo tree less
|
||||||
|
painful.
|
||||||
|
|
||||||
|
==============================================================================
|
||||||
|
2. Usage *GundoUsage*
|
||||||
|
|
||||||
|
We'll get to the technical details later, but if you're a human the first
|
||||||
|
thing you need to do is add a mapping to your |:vimrc| to toggle the undo
|
||||||
|
graph: >
|
||||||
|
|
||||||
|
nnoremap <F5> :GundoToggle<CR>
|
||||||
|
|
||||||
|
Change the mapped key to suit your taste. We'll stick with F5 because that's
|
||||||
|
what the author uses.
|
||||||
|
|
||||||
|
Now you can press F5 to toggle the undo graph and preview pane, which will
|
||||||
|
look something like this: >
|
||||||

|
||||||
|

Preview pane
|
||||||
|
|
||||||
|
Your current position in the undo tree is marked with an '@' character. Other
|
||||||
|
nodes are marked with an 'o' character.
|
||||||
|
|
||||||
|
When you toggle open the graph Gundo will put your cursor on your current
|
||||||
|
position in the tree. You can move up and down the graph with the j and
|
||||||
|
k keys.
|
||||||
|
|
||||||
|
You can move to the top of the graph (the newest state) with gg and to the
|
||||||
|
bottom of the graph (the oldest state) with G.
|
||||||
|
|
||||||
|
As you move between undo states the preview pane will show you a unified diff
|
||||||
|
of the change that state made.
|
||||||
|
|
||||||
|
Pressing enter on a state (or double clicking on it) will revert the contents
|
||||||
|
of the file to match that state.
|
||||||
|
|
||||||
|
You can use p on a state to make the preview window show the diff between
|
||||||
|
your current state and the selected state, instead of a preview of what the
|
||||||
|
selected state changed.
|
||||||
|
|
||||||
|
Pressing P while on a state will initiate "play to" mode targeted at that
|
||||||
|
state. This will replay all the changes between your current state and the
|
||||||
|
target, with a slight pause after each change. It's mostly useless, but can be
|
||||||
|
fun to watch and see where your editing lags -- that might be a good place to
|
||||||
|
define a new mapping to speed up your editing.
|
||||||
|
|
||||||
|
Pressing q while in the undo graph will close it. You can also just press your
|
||||||
|
toggle mapping key.
|
||||||
|
|
||||||
|
==============================================================================
|
||||||
|
3. Configuration *GundoConfig*
|
||||||
|
|
||||||
|
You can tweak the behavior of Gundo by setting a few variables in your :vimrc
|
||||||
|
file. For example: >
|
||||||
|
|
||||||
|
let g:gundo_width = 60
|
||||||
|
let g:gundo_preview_height = 40
|
||||||
|
let g:gundo_right = 1
|
||||||
|
|
||||||
|
------------------------------------------------------------------------------
|
||||||
|
3.1 g:gundo_width *gundo_width*
|
||||||
|
|
||||||
|
Set the horizontal width of the Gundo graph (and preview).
|
||||||
|
|
||||||
|
Default: 45
|
||||||
|
|
||||||
|
------------------------------------------------------------------------------
|
||||||
|
3.2 g:gundo_preview_height *gundo_preview_height*
|
||||||
|
|
||||||
|
Set the vertical height of the Gundo preview.
|
||||||
|
|
||||||
|
Default: 15
|
||||||
|
|
||||||
|
------------------------------------------------------------------------------
|
||||||
|
3.3 g:gundo_preview_bottom *gundo_preview_bottom*
|
||||||
|
|
||||||
|
Force the preview window below current windows instead of below the graph.
|
||||||
|
This gives the preview window more space to show the unified diff.
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
+--------+ +--------+
|
||||||
|
!g! ! ! !g!
|
||||||
|
!g! ! or ! !g!
|
||||||
|
!g!______! !______!g!
|
||||||
|
!g!pppppp! !pppppp!g!
|
||||||
|
+--------+ +--------+
|
||||||
|
|
||||||
|
Default: 0
|
||||||
|
|
||||||
|
------------------------------------------------------------------------------
|
||||||
|
3.4 g:gundo_right *gundo_right*
|
||||||
|
|
||||||
|
Set this to 1 to make the Gundo graph (and preview) open on the right side
|
||||||
|
instead of the left.
|
||||||
|
|
||||||
|
Default: 0 (off, open on the left side)
|
||||||
|
|
||||||
|
------------------------------------------------------------------------------
|
||||||
|
3.5 g:gundo_help *gundo_help*
|
||||||
|
|
||||||
|
Set this to 0 to disable the help text in the Gundo graph window.
|
||||||
|
|
||||||
|
Default: 1 (show the help)
|
||||||
|
|
||||||
|
------------------------------------------------------------------------------
|
||||||
|
3.6 g:gundo_disable *gundo_disable*
|
||||||
|
|
||||||
|
Set this to 1 to disable Gundo entirely.
|
||||||
|
|
||||||
|
Useful if you use the same ~/.vim folder on multiple machines, and some of
|
||||||
|
them may not have Python support.
|
||||||
|
|
||||||
|
Default: 0 (Gundo is enabled as usual)
|
||||||
|
|
||||||
|
------------------------------------------------------------------------------
|
||||||
|
3.7 g:gundo_map_move_older, g:gundo_map_move_newer *gundo_map_move_older*
|
||||||
|
*gundo_map_move_newer*
|
||||||
|
|
||||||
|
These options let you change the keys that navigate the undo graph. This is
|
||||||
|
useful if you use a Dvorak keyboard and have changed your movement keys.
|
||||||
|
|
||||||
|
Default: gundo_map_move_older = "j"
|
||||||
|
gundo_map_move_newer = "k"

The graphing code was all taken from Mercurial, hence the GPLv2+ license.
|
||||||
|
|
||||||
|
The plugin was heavily inspired by histwin.vim, and the code for scratch.vim
|
||||||
|
helped the author get started.
