Vim how to reload syntax highlighting

Question

When I run Rmodel, Rcontroller and others in Vim. I see only white text. But when I go to the next buffer and then return to :bn and :bl , the colors work.

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

Answer 1

Use :syntax sync fromstart

I got this advice from http://vim.wikia.com/wiki/Fix_syntax_highlighting

This article also suggests creating a mapping for this command, for example. to display F12:

 noremap <F12> <Esc>:syntax sync fromstart<CR> inoremap <F12> <Co>:syntax sync fromstart<CR> 

Answer 2

Try:

 :e 

If you do not have unsaved changes to the file.

Or:

 :syn off | syn on 

Answer 3

Sometimes the syntax is fine, but all that breaks is the folds. In this case, zx helps a lot.

From the VIM documentation:

gh

Refresh folds: cancel open and closed folds manually: re-apply 'foldlevel', then do “zv”: view the cursor line. Also makes recount folds. This is useful when using 'foldexpr', and the buffer is changed in such a way that causes wrinkles to not be updated properly.

Answer 4

Another variant:

 doautocmd Syntax 

Answer 5

I tried all of the above - no one worked for me.

The only thing that works:: :filetype detect so I redid the quick shortcut :noremap <Leader> :filetype detect

Answer 6

Try:

 :Rrefresh! 

This command updates certain cached settings and also reloads rails.vim .
This will help me update the syntax highlighting in Rails.
