From 8286a944766c241bcfe0bde1108c2dc7ca798829 Mon Sep 17 00:00:00 2001 From: Edson Eddy Date: Sun, 18 Jan 2026 03:40:04 -0400 Subject: [PATCH 01/22] Updated README.md and parser_gen_guide.md with clearer, step-by-step instructions for setting up ANTLR. Corrected the antlr4 command to output generated files directly to the target directory, avoiding incorrect nested paths. Improved overall grammar and readability in the documentation. --- README.md | 20 +----- csim/CodeSimilarity.py | 8 +-- csim/{ => python}/PythonLexer.interp | 0 csim/{ => python}/PythonLexer.py | 2 +- csim/{ => python}/PythonLexer.tokens | 0 csim/{ => python}/PythonLexerBase.py | 0 csim/{ => python}/PythonParser.interp | 0 csim/{ => python}/PythonParser.py | 2 +- csim/{ => python}/PythonParser.tokens | 0 csim/{ => python}/PythonParserVisitor.py | 2 +- csim/python/__init__.py | 0 csim/python/py_utils.py | 89 +++++++++++++++++++++++ csim/utils.py | 90 ------------------------ grammars/README.md | 10 --- grammars/parser_gen_guide.md | 81 +++++++++++++++++++++ 15 files changed, 179 insertions(+), 125 deletions(-) rename csim/{ => python}/PythonLexer.interp (100%) rename csim/{ => python}/PythonLexer.py (99%) rename csim/{ => python}/PythonLexer.tokens (100%) rename csim/{ => python}/PythonLexerBase.py (100%) rename csim/{ => python}/PythonParser.interp (100%) rename csim/{ => python}/PythonParser.py (99%) rename csim/{ => python}/PythonParser.tokens (100%) rename csim/{ => python}/PythonParserVisitor.py (99%) create mode 100644 csim/python/__init__.py create mode 100644 csim/python/py_utils.py delete mode 100644 grammars/README.md create mode 100644 grammars/parser_gen_guide.md diff --git a/README.md b/README.md index 8a01f01..120ec07 100644 --- a/README.md +++ b/README.md @@ -46,24 +46,8 @@ similarity = Compare(code_a, code_b) print(f"Similarity: {similarity}") ``` -## Parser Generation - -This section describes how to regenerate the parser files using ANTLR 4.
