vim-latex suite, how to open a file without folding the text by default

Question

I have downloaded and successfully installed the Vim-LaTeX Suite from http://vim-latex.sf.net.

It is a great tool, but slightly annoying that when you open a file it folds all of the text and puts the folds in a collapsed state, as this page of the manual states:

http://vim-latex.sf.net/documentation/latex-suite/latex-folding.html

So you have to type zR to expand everything each time you open a LaTeX file.

Typing zR is obviously not hugely annoying, but I was wondering if there was an easy way to disable this functionality, so that the file is displayed with the folds uncollapsed by default?

Answer 1

Put the following into ~/.vim/after/ftplugin/tex.vim:

setlocal foldlevel=999

This way, folding is kept intact, and all folds are only opened for Latex files. You can close all folds with zM.

_{(This requires that you have :filetype plugin on; use of the after directory allows you to override any default filetype settings done by $VIMRUNTIME/ftplugin/<filetype>.vim.) Alternatively, you could define an :autocmd FileType <filetype> setlocal directly in your ~/.vimrc, but this tends to become unwieldy once you have many customizations.}

Answer 2

Add the following line to your ~/.vimrc:

set nofoldenable

Answer 3

or set foldlevel to a higher value, e.g. 999

actually, the zM, zR was setting this option too.
