Support for fish/gdscript

[CaptainJawZ]

Hello, I was wondering if support for fish and gdscript could be added?
I noticed that highlight.js has support at least for gdscript, fish is a bit confusing (I could go ask), I am not too familiar with the source code, but looking around i think it would only be a matter of modifying these 2 files
https://github.com/pawelmalak/snippet-box/tree/master/client/src/data
which are just two json files, if you could point me as to where you got a list of all the aliases, I could probably make a quick shell script that updates those two json files to include whatever new languages highlight.js adds.
