Tree-Sitter parses programming languages based mostly mostly into a concrete syntaxtree. From there, now not supreme can syntax highlighting might perchance even be executed at excessivedisappear, nonetheless an spectacular deeper analysis of the code is possible and actionscorresponding to syntax manipulation can additionally be accomplished for the rationale that syntax treeitself is on hand as an object that is also manipulated!
In case you admire to possess some more records on Tree-Sitter itself, you might perchance per chancecheck out the legit Tree-Sitter net siteotherwise you might perchance per chance even check thisfocus on out given by Tree-Sitter’s creator, Max Brunsfeld.
Successfully, here is now a local resolution in Emacs! Currently, Emacs’Tree-Sitter helps the most modern foremost modes :
