Question

In my .vimrc I\'ve put set foldmethod=syntax to enable folding of methods etc. However, I don\'t like the default that everytime I open a file, the who

Answer 1

You can put this in your .vimrc: au BufRead * normal zR

It declares an automatic command (au), triggered when a buffer is read (BufRead), matching all files (*) and executes the zR (opens all folds) command in normal mode.

Answer 2

You could map it to keys to enable it. For example,

nmap ,f :set foldmethod=syntax<CR>

Then while in normal mode hit the ",f" key combination

Answer 3

In .vimrc add an autocmd for BufWinEnter to open all folds automatically like this:

autocmd BufWinEnter * silent! :%foldopen!

That tell vim to execute the silent :%foldopen! after opening BunWinEnter event (see :h BufWinEnter). The silent %foldopen! will execute foldopen on the whole buffer thanks to the % and will open all folds recursively because of the !. Any eventual error message will be suppressed by silent. (You could get error messages like E490: No fold found if the buffer actually didn't contain any fold yet)

Note: You could use BufRead instead of BufWinEnter but then if the file has a modeline that enables the folding that will override this autocmd. I mean BufRead autocmds run before the modeline is processed and BufWinEnter will run them after. I find the later to be more useful

Answer 4

set foldlevel=99

should open all folds, regardless of method used for folding. With foldlevel=0 all folded, foldlevel=1 only somes, ... higher numbers will close fewer folds.

Answer 5

set nofoldenable

Adding this to your .vimrc will temporarily disable folding when you open the file, but folds can still be restored with zc

Answer 6

You can open unfolded file when you put set nofoldenable into your .vimrc file.
