Claude 225d40cea5 Language: struct types ... Adds composite \`struct\` types with field access: struct Vec2 { x: u8, y: u8 } var pos: Vec2 pos.x = 100 pos.y = pos.x + 5 - Lexer: \`struct\` keyword - AST: \`StructDecl\` with \`StructField\` list; \`NesType::Struct(name)\` for struct-typed variable declarations; \`Expr::FieldAccess\` and \`LValue::Field\` for reads/writes - Parser: top-level \`struct Name { field: type, ... }\` (optional trailing comma) and \`ident.field\` syntax in both expression and lvalue position - Analyzer: \`register_struct\` computes contiguous field offsets (no padding) and stores them in \`struct_layouts\`. Struct variables synthesize a \`VarAllocation\` per field under the name \`"struct_var.field"\`, and \`Expr::FieldAccess\` / \`LValue::Field\` resolve against those. Unknown struct types and unknown fields emit E0201. - IR lowering + AST codegen: treat struct field access as ordinary variable access against the synthetic per-field symbols. No new IR ops are needed. v1 structs only support primitive fields (u8/i8/bool). Nested structs, u16 fields, and array fields are not yet allowed. https://claude.ai/code/session_01W6eQFStA66EuMKHUFo2rx3		2026-04-12 16:18:05 +00:00
