Building an LSP Server in Zig
summary
A developer builds an HTML language server called SuperHTML language server and a static site generator called Zine static site generator using Zig, first trying TreeSitter then writing a custom HTML parser that treats unclosed tags as errors (trading spec compliance for useful diagnostics). The LSP is deployed on the VS Code marketplace, uses a Zig LSP kit for boilerplate, and hardens stability with coverage-guided fuzzing plus a generator tool (supergen); fuzzing finds real crashes in seconds and improves robustness.
