Hi all,
I'd like to use the [Hare](https://harelang.org/) programming language with Geany. I see that the C syntax highlighting works ok so far (and it appears that [Lexilla](https://github.com/ScintillaOrg/lexilla) (which I understand Geany makes use of) supports C, C++, Java, and JS all using the same lexer: https://github.com/ScintillaOrg/lexilla/blob/master/lexers/LexCPP.cxx
Anyhow, when I open a .ha file (Hare source file) with Geany, I'd like for it to just use the C syntax highlighting automatically, so I don't have to manually select it each time. How can I get that to work?
You also need to specify the filetype in `filetype_extensions.conf` and note the filetype name you use there and the filetype name used in the `filetype.XXX.conf` filename are case sensitive and must match exactly.
Note that you can open `filetype_extension.conf` in the menu `Tools->Configuration Files` and it will open the one in your user config, or the system one if no user one yet, but always saves to your user config.
I'm on GNU/Linux, and I see that I've got a ~/.config/geany directory.
Looking at the manual, I don't understand the different axes of filetype def files vs config files ...
I see that I have a /usr/share/geany/filedefs/filetypes.c file. Do I copy that to my ~/.config/geany/filedefs dir? After that, what do I change in that file?
Correct target directory, but what you need is a "custom filetype" which can specify which lexer and/or existing parser to use, see https://www.geany.org/manual/current/index.html#custom-filetypes. There are examples of custom filetypes in the system filedefs directory, eg Scala.
Also, why do some of the files in /usr/share/geany/filedefs end in .conf while others don't?
Custom filetypes vs builtin filetypes.
Cheers Lex
