Re: Scripting the enter key

Thanks for the tip on <expr>, I hadn't known about it!

Long story short, I was using 'autoclose' to do what delimitmate does, and was looking to add the CR expansion myself.  It turns out that delimitmate does everything that autoclose does, with smarter handling of matching (e.g. dm: I'm versus ac: I''m), and adds the functionality as you've mentioned.

The only caveat was that SuperTab (which I don't use, but was hanging around in my bundle directory) conflicts with delimitmate, and so I had to remove it.

In any case, I've got exactly what I was looking for, so thanks!

Cheers,

Doug

Here's a few pointers:

1. If you use an <expr> map (or if start your mapping with <C-R>= instead of :), you can remain in insert mode when the mapping completes, without need for the <C-\><C-O>
2. Whenever you leave insert mode, and the line has nothing but whitespace, and you have made no changes to the line in insert mode other than whitespace, Vim will automatically remove the whitespace on the line. I think this (combined with temporarily leaving insert mode) may be why your indent is not what you expect it to be.
3. There are plugins which can do your desired task already. For example, DelimitMate. http://www.vim.org/scripts/script.php?script_id=2754 Note this plugin is primarily for inserting matched pairs together, but it also does balanced insertion of spaces and line breaks within empty matched pairs. See http://vim.wikia.com/wiki/Automatically_append_closing_characters#Plugins

Were I doing what you ask by hand, I'd have a mapping which basically does one of these (starting from insert mode):

<CR><Esc>O
<CR><CR><Esc>kcc
