The nvim-treesitter highlights files that we're using for most of our

supported languages make use of several custom predicates and

directives.


This change implements the following:


    

  • any-contains?
    • 

  • contains?
    • 

  • gsub!
    • 

  • has-ancestor?
    • 

  • has-parent?
    • 

  • not-has-ancestor?
    • 

  • not-has-parent?
    • 



Directives used in queries files which are not (yet) implemented here:


    

  • offset!
    • 



Predicates and directives implemented in neovim but which are not used

in any of the query files we are using:


    

  • any-lua-match?
    • 

  • any-vim-match?
    • 

  • not-vim-match?
    • 

  • vim-match?
    • 

  • trim!
    • 


 








  


 
 

  
    

  • Ran unit tests.
    • 

  • Verified that syntax highlighting that used these predicates and
    
  directives worked as expected.
    •
