Vim, how to reload syntax highlighting

Vim Problem Overview

When I execute Rmodel, Rcontroller and others in Vim. I see only white text. But when I go to next buffer and then go back by :bn and :bl, colors are working.

This is my .vim folder https://github.com/regedarek/dotvim

Vim Solutions

Solution 1 - Vim

Use :syntax sync fromstart

I got that tip from http://vim.wikia.com/wiki/Fix_syntax_highlighting

That article also suggests creating a mapping for that command e.g. to map F12:

noremap <F12> <Esc>:syntax sync fromstart<CR>
inoremap <F12> <C-o>:syntax sync fromstart<CR>

Solution 2 - Vim

Try:

:e

If you have no unsaved changes to the file.

Or:

:syn off | syn on

Solution 3 - Vim

Tried all the above - none worked for me.

The only thing that does work is: :filetype detect so I remapped a quick shortcut :noremap <Leader>,ftd :filetype detect

Solution 4 - Vim

Sometimes syntax is OK, but all that is getting broken are foldings. In that case zx helps alot.

From VIM documentation:

> zx > > Update folds: Undo manually opened and closed folds: re-apply > 'foldlevel', then do "zv": View cursor line. > Also forces recomputing folds. This is useful when using > 'foldexpr' and the buffer is changed in a way that results in > folds not to be updated properly.

Solution 5 - Vim

Another option is:

doautocmd Syntax

Solution 6 - Vim

You can also try:

CTRL-L

From the VIM docs (:h CTRL-L): > Clear and redraw the screen. The redraw may happen later, after processing typeahead.
