What parsing techniques do you use to support a good language server?

• TypeScript

  1,302 97,832 9.9 TypeScript

  TypeScript is a superset of JavaScript that compiles to clean JavaScript output.

  

The situation I want to avoid is one which I've encountered in some hobby languages that I've tried, which is that any syntax error anywhere in the file causes the entire file to red squiggly. IMO, this is worse than nothing at all. TypeScript handles this problem very well; you can have multiple syntax errors in different places in the file, and each of them will report errors at a local scope. (I assume this has to do with balancing brackets, because unbalanced parenthesis seem like the easiest way to cause non-local syntax errors.) Problem is, at 9.5k lines of imperative code, trying to read the TypeScript parser hasn't made anything click for me.

I made a toy language awhile back that might help. It's mostly based on the "crafting interpreters" series but more functional (with types). There's a simple language server as well as a debugger. It's all in typescript. Github repo

It must be a fairly large echo chamber since it has room for Clang, GCC, V8, OpenJDK, Roslyn, etc. (The Zend parser for PHP seems to use some flavor of YACC, but given PHP, I don't know if that strengthens or weakens my point.)

  JDK main-line development https://openjdk.org/projects/jdk
