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 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.
