Split windows and syntax highlighting

[Matthias Pitzl]

Hi there!

Is it somehow possible to do a :syn off only for one specific window?

Thanks in advance!

Yes, if you use :setl syntax=off
:syn off will turn off syntax highlighting globally.

or just :setl syntax= (with nothing after the = sign)

If by any chance you had downloaded a syntax/off.vim in one of the
directory trees part of 'runtimepath', ":setl syntax=off" would apply it
to the current editfile.

Considering, that the advised method of disabling syntax highlighting
in the help is using :set syntax=OFF we should probably prevent loading a
syntax file with the name OFF and handle this in synload.vim (as it is
already done for the value 'ON')

Here is a patch, that does that (and additionally makes the check for
the syntax item ignore case):
--- syntax\synload.vim Tue Sep 25 08:09:53 2012
+++ syntax\synload.vim.new Tue Sep 25 08:09:43 2012

let s = expand("<amatch>")

echohl None
endif
let s = &filetype
+ elseif s ==? "OFF"

endif

if s != ""

Hi Christian,

Works like a charm! Thanks a lot!

Somehow :setl syn=ON (or even :setl syn=on) seems to set the syntax
highlighting according to the value of 'filetype', but :setl syn?
answers " syntax=ON" or " syntax=on" respectively. From what I see
above it sems to be the intended behaviour. Didn't know that.

As long as there is _no_ off.vim syntax script (and who would install a
syntax script of that name?), the behaviour for an "unknown" syntax is
to highlight everything like the Normal group anyway.


Best regards,
Tony.

I guess, that is what is meant by :h 'syntax':
