Adds a way change which grammars get built and included by adding an
override
function to the helix package that takes anincludeGrammarIf
attribute which is a function that decided whether the grammar should be included (true
) or not (false
). This also avoid fetching all of the grammars if you don't need them (like me) which speeds up fetching stuff when you are fetching when the sources aren't cached already. I also addedmakeWrapperArgs
to theoverride
function so it can be set there, I think @nrdxp asked about this.
