In my current vim setup I have set foldmethod=syntax , however whenever I save my file it refolds anything I had opened. Any ideas?
FWIW this is my current vimrc
This behavior is normal. Vim's default is not to remember which code you had folded vs. unfolded from one session to the next. You can save your current folds; when you finish editing a file, before exiting vim, enter the command :mkview. When you next open the file, if you enter :loadview, it will restore your folds. If you want this to happen automatically, add this code to your vimrc
augroup remember_folds
autocmd!
autocmd BufWinLeave * mkview
autocmd BufWinEnter * silent! loadview
augroup END
If you want more features, this plugin does the same thing http://www.vim.org/scripts/script.php?script_id=4021.
Update: sorry, my original code didn't work. It should work now.
