autocmd

This is because I'd like to automatically run tests after each file save. I have looked at autocmd and BufWritePost but cannot make it work. Alex Howell This runs run_tests.sh after any file is saved, with the current filename as the only parameter: :autocmd BufWritePost * !run_tests.sh <afile> View the auto-command with: :autocmd BufWritePost * And remove all auto-commands from the previous with: :autocmd!

I have a Vim autocmd that removes trailing whitespace in files before write. I want this almost 100% of the time, but there are a few filetypes that I'd like it disabled. Conventional wisdom is to list the filetypes you want an autocmd to run against in a comma-separated list, eg: autocmd BufWritePre *.rb, *.js, *.pl But in this case that would be onerous. Is there a way to match an autocmd pattern against all files EXCEPT those matching the pattern? I cannot find the equivalent to a NOT matcher in the docs. *.rb isn't a filetype. It's a file pattern. ruby is the filetype and could even be set
