Automatically check PHP / Ruby syntax on file save
One of the wicked things about VIm is that you learn a new trick every day; well, I do anyway.
I program day to day in either PHP or Ruby, and I normally run a quick syntax check when I save a file. Previously, I would save the file and run the following from the terminal
php -l filename.php
ruby -cw filename.rb
Then I copped that I could run it without leaving VIm by entering the follwowing commands
:! php -l %
:! ruby -cw %
So the next nicety was to have VIm run the check automatically when I save either a PHP or Ruby file.
Simple pop the following in your vimrc and away you go.
au BufWritePost *.php !php -l % au BufWritePost *.rb !ruby -cw %
This simple instructs VIM that when saving a file with either extension, run the required command. Dead handy,…. and you can swap out the extension and command required for your language of choice. Enjoy,
