I've successfully created a new custom filetype using the Geany guide, however upon opening the file itself later I find I always have to manually set the filetype (Document > Set Filetype) instead of Geany auto-detecting it (the way it usually does with pre-configured filetypes like .md, .cs, etc).
Is there a reason for this? How can I get Geany to autodetect the filetype of a new custom filetype without having to manually set it everytime?
Thank you everyone.
