So I learned yet another awesome feature in vim today - code folding.
For those of you who don’t know what I’m talking about, code folding lets you shrink the contents of multiple lines of code into 1 line. A lot of the better code editors out there do it, like Dreamweaver and ZendStudio. It’s a handy feature when you have scripts with hundreds of lines of code.
There are several
ways you can fold a portion of code in vim. You could type
for instance, and the 10 lines under the cursor would be folded.
You could also specify the start and end lines manually with
:[start line],[end line]fold
An easy way I saw to do this, is to use Shift+V in command mode. This will
let you highlight lines of code. So it’s as simple as pressing
then the down arrow until you’ve highlighted a section of code.
Then you can press zf to fold (or type in
Cool right? There’s one more thing I did to keep these folds from session to
session - normally folds will disappear after you close vim unless you
create what is called a view. I found a page
on vim.org that explains how to do this automatically. Just add these lines
autocmd BufWinLeave *.* mkview autocmd BufWinEnter *.* silent loadview
This will save your folds when you exit a document and load them when you open it.
