Re: Switching syntax highlighting

Hello all!
I'm trying to write a function for switching between the current buffer syntax highlighting and whitespace, but I'm really new to vim scripting and such and am having a hard time.
I switch to whitespace syntax highlighting and back quite frequently. However, it's not as simple as switching back to the buffer's filetype syntax because there are times when I've changed it to something else. For instance, data in .txt files that I visualize with different syntax highlighting formats depending on the situation.

What I've tried is creating a buffer variable on buffer creation and then updating it, this is what I have so far:

au BufEnter * let b:current_syntax=&syntax
fu! SwitchHLwhitespace()
    if &syntax == "whitespace"
        let &syntax=b:current_syntax
    else
        let tmp=&syntax
        set syntax=whitespace
        let b:current_syntax=tmp
    endif
endfunction



Didn't quite follow what you are tying to do with whitespace.

I know at times you want to see "invisible" stuff, like tabs, whitespace, special codes and so on.

I use this plugin:

cream-showinvisibles : Toggle view of invisible tabs, returns, trailing spaces 


Anytime I want to see that stuff, I just hit F4 (that is the default mapping for the plugin).

HTH,
David
