You may try <https langium org |Langium framework >if you need it in the JS world

Denis Kuniß · Answer

Sorry hit the enter button too fast I ve some more to say For the Java environment <https www eclipse org Xtext |Xtext> is a good choice historically the predecessor of Langium both are sharing the same idea approach The main advantage for your requirement is I guess that by defining the concrete syntax grammar implicitly a tree data algebra is defined what the parser is using to create the tree representation of a sentence of your language You may see this as a Concrete Syntax Tree and process it that way Or did I interpret your CST wrongly

Nicholas Yang · Answer

Interesting Yeah I like the idea of something that is explicitly integrated with language servers and therefore IDEs I m writing a blog post about these precise tools what I call tooling for tooling that I ll probably post here soon
