GiggleLiu Date: Sun, 11 Jan 2026 01:17:18 +0800 Subject: [PATCH 02/10] Refactor to use type-based dispatch and cleanup unused code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Created QASMCommon module for shared type conversions - Used typename customization to avoid method collisions - QASM2_ prefix for v2.0 parser - QASM3_ prefix for v3.0 parser - Removed 115 lines of unused code from qasm_common.jl - Removed unused token patterns that weren't being used - Removed grammar rule functions (RBNF doesn't support function interpolation) - Added CX gate support to v3 parser for full QASM 2.0 compatibility - Fixed multi-character operators (==, !=, <=, >=, &&, ||, **) - Match as character sequences since lexer splits them - All 185 tests passing (133 v2.0 + 52 v3.0) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- src/parse_v3.jl | 5 +- src/qasm_common.jl | 137
