Fortran

Declarative tree-sitter query plugin powered by QueryLanguagePlugin (rgctl-lang-runtime) and crates/rgctl-lang-fortran/queries/tags.scm. Compiles once at startup, validates captures against the Tier-2 vocabulary gate, and extracts symbols, container hierarchy (Container::member), imports, and call edges.

Grammar Crate: tree-sitter-fortran
Plugin: QueryLanguagePlugin (rgctl-lang-fortran)
Extensions: .f90, .f95, .f03, .f08, .F90
Discover: rgctl discover . -l fortran
Function Kinds: function, subroutine
Class / Container Kinds: derived_type_definition

Capture summary

Capture	Patterns	Graph mapping
@definition.class	1	Emits SymbolType::Class (acts as enclosing container).
@definition.function	2	Emits SymbolType::Function (acts as caller scope & container).
@definition.module	1	Emits SymbolType::Module (acts as enclosing container).
@import.path	1	Emits SymbolType::Import with normalized import_path metadata.
@name	6	Symbol identifier or target callee/type name.
@reference.call	2	Emits RelationType::Calls from innermost enclosing function to @name.
