I'm using LESS CSS (PHP version). I'm also using Geany in Linux. Is there a LESS syntax file for Geany out there, or how I can go about editing the CSS one to suit LESS?

This should work. Just update your configuration file filetype_extension.conf.

  1. Open ~/.config/geany/filetype_extensions.conf
  2. Change this line: CSS=*.css; to this: CSS=*.css;*.less;
  3. Save configuration file.

You can also edit directly from geany with Tools > Configuration Files > filetype_extensions.conf – Azmisov Oct 7 '15 at 23:34

You can also add following into your ~/.config/geany/filedefs/filetypes.css - file

It works! At last, nested rules are highlighted, awesome :). To make it work, I created the file filetypes.css, copied the two lines in it, saved it, logged out and logged in again. – rom Apr 24 '15 at 17:50
Thanks! I wonder why this setting is not the default. – Prahlad Yeri Dec 3 '15 at 12:05

This might be due to a different version, but from within Geany 0.20 you can go to the

main menu > Tools > Configuration Files > filetype_extensions.conf

Prior to accessing the filetype_extensions.conf file in this way the file did not exist in the above mentioned location. Once the changes are saved the file can be found there.
