The Vim Code

"You can use <c-j> to goto the next <++> - it is pretty smart.

"Press c-q insted of space (or other key) to complete the snippet
imap <C-q> <C-]>

Explanation

If you in a Javascript document type cfun<C-q> then this will be unfolded to (| is the cursor position).

function |(<++>) {
<++>;
return <++>;
}

<++> are place-holders. You can press <C-j> to get to the next <++> and edit there.

This approach makes it very fast to create new functions, if-else statements etc. It reduces the movement and you get pretty addicted to these snippets. It's very easy to create similar snippets for other languages.

Requirement

I have used the modified version of imaps.vim.

The modified version of imaps.vim is found in the LaTeX-Suite package and it can be downloaded from my own site (http://amix.dk/vim/imaps.vim). This script gives the needed functionality.

My vimrc

I have also uploaded my very good documented vimrc (about 800 lines). Check it out at http://www.amix.dk/vim/vimrc.html

Comments

Here is one for Java:

autocmd BufRead,BufNewFile *.java inorea <buffer> cfun <c-r>=IMAP_PutTextWithMovement("public <++> <++>(<++>) {\n<++>;\nreturn <++>;\n}")<CR>
autocmd BufRead,BufNewFile *.java inorea <buffer> cfunpr <c-r>=IMAP_PutTextWithMovement("private <++> <++>(<++>) {\n<++>;\nreturn <++>;\n}")<CR>
autocmd BufRead,BufNewFile *.java inorea <buffer> cfor <c-r>=IMAP_PutTextWithMovement("for(<++>; <++>; <++>) {\n<++>;\n}")<CR>
autocmd BufRead,BufNewFile *.java inorea <buffer> cif <c-r>=IMAP_PutTextWithMovement("if(<++>) {\n<++>;\n}")<CR>
autocmd BufRead,BufNewFile *.java inorea <buffer> cifelse <c-r>=IMAP_PutTextWithMovement("if(<++>) {\n<++>;\n}\nelse {\n<++>;\n}")<CR>

I think things like this sould be made plugins. This is no way a tip.

Arkanus: I don't know, but adding the imap plugin isn't enough, I got a "function X" only and not the complete snippet; but with your .vim directory I get the complete snippet Nevermind i've figured it out; you need to add "set laststatus=2" to your .vimrc I don't know why, but without it the thing doesn't work
