In a new post to his site Christian Weiske shares an update he contributed to the PHP_CodeSniffer functionality to make working with and checking the validity of local PHP code easier - a notifier for PHP_CodeSniffer using the "notify-send" commonly installed in most Linux distributions.
I use emacs as IDE, and wanted to have direct feedback about the validity of my .php files when writing them. The most easy way was to add a save hook that runs PHP_CodeSniffer - but the results should be displayed in a nice, unobtrusive way. phpcs has multiple reporting modes - xml, checkstyle, csv etc. - but nothing for the desktop. I thought that notify-send would be the right fit since it is able to display pretty popup messages without getting in the way.
He also includes the details on his original objective - including it in a "on save" hook as well as providing it in a keystroke shortcut, making checking his code even easier.
