Documentation

Overview

Package parse turns .sel source into the high-level material model (hir). It generates the Selena tree-sitter language from grammar.SelenaGrammar via grammargen (the same engine as .gsx), parses the source, and walks the tree into a hir.Material. This is the front-end: with it, materials are authored as .sel files rather than hand-built HIR.
