In Vim how I can set a local match only for a specific filetype?

In Vim I can set local configuration as:

 setlocal number

How I can set a local match only for a specific filetype?

I use this:

 autocmd! BufEnter *.py,.vimrc,*.sh,*.c* :match ColorColumn /\%>80v.\+/

But when I open a file of another filetype, in the same session, this gives me the match ColorColumn.

This might no longer be useful to the author, but I put the following in .vim/ftplugin/python.vim:

if exists('+colorcolumn')
    setlocal colorcolumn=81
else
    au! BufEnter <buffer> match ColorColumn /\%81v.*/
endif

Since it's in ftplugin, it only occurs for python files, and BufEnter keeps it local to the buffer that the python file is in.

I solved it with this:

augroup longLines
    autocmd! BufEnter *.py,.vimrc,*.sh,*.c* :match ColorColumn /\%>80v.\+/                      
augroup END

I didn't actually understand your question to the detail, but that doesn't exactly do what you asked for. – Rook – 13 years ago

my question is, if I open many files, how activate the match only in some files? – juanpablo – 13 years ago

"many files" ?? Many files of a certain filetype or by extension or ... ? Filetype is activated by autocmd FileType, BufEnter by opening a buffer. Depends on what you want. Could you try to explain it a bit further? – Rook – 13 years ago

many files, some *.py, some *.c, some *.txt – juanpablo – 13 years ago

See my answer. Is that what you wanted? – Rook – 13 years ago

This will make the highlighting active when Python or C filetypes are open (feel free to add the others in there. I didn't know what filetype *.sh extension belongs to), and make it go away for all the others.

augroup LongLines
    autocmd!
    autocmd FileType * match none
    autocmd FileType python,c,sh match ColorColumn /\%>80v.\+/
augroup END

*.sh is a bash file, a sh filetype – juanpablo – 13 years ago
