How to undo specific line in vim

vim

I have lots of modifications in a file, but I want to undo specific line to initial state which keep other lines at current state.

Is there a way to do it in vim?

Best Answer

There is no built in way to undo a line.

What I usually do is to undo u until I am at the changes I want to keep, copy the line or block of text and then do a :e! to reset the file and paste the changes.

A great plugin that I use for more complex changes is Undo Tree

Make Vim display a line at the edge of the set textwidth

for (g)vim, use the following:

set colorcolumn=80

or whatever width you wish. Works in both vim & gvim. I have mine within an IF so it's conditional based on which type of files I edit.

You may also use a +x/-x to base position of the column +/- from &textwidth.

set textwidth=80
set colorcolumn=-2

would effective draw the colored bar at char position 78. Of course, you may or may not set textwidth yourself, so it might be 0 (default). I use the absolute position form.

You may also change the color used if you wish:

highlight ColorColumn ctermbg=green guibg=orange

(I don't recommend THOSE colors though)

This option was added in (g)vim 7.3.

Vim line wrap with indent

UPDATE: This functionality landed in vim 7.4.338, though you'll want 7.4.354 or later.

So apparently this requires a patch to Vim. There is a patch by Vaclav Smilauer from back in 2007. I updated the patch to work with Vim 7.2.148 from Fedora 11. But it does seem to do the job.
