Add GUI option to import .lang files

GarkGarcia commented 4 years ago

Prerequisites

[x] I have searched open and closed issues for duplicates.

Feature

As far as I can tell, Code uses gtk-sourceview for syntax highlighting. Therefore, it should be easy to add new language definitions by simply placing the .lang and a mimetype file in the appropriate folders. However, Code does not offer a way to it through it's GUI. Instead, users have to manually install the language definition, or file a Github issue to get their favourite languages supported.

My solution is simple. Include an option for the user to import .lang files. It could be placed in the Syntax Highlighting menu. If there is already a mimetype file installed that references the new language definition, then that mimetype would be used. Otherwise the user would be prompted to create a new mimetype.

Alternatives

Have the user manually install new language definitions.
Have the user file an issue in this repo to get official support for his language of choice.

I agree, this would be much nicer than telling developers to go manually drop a file into the filesystem.
