Simpleafier 0.1.0

A command line tool to help improve the quality of Lean code by converting any "simp" to "simp only".

Simpleafier

Simpleafier is a command line tool to help improve the quality of Lean code by converting any simp to simp only. This can help make Lean proofs more robust and maintainable by restricting the set of lemmas used by simp.

Requirements

• Python 3.6+
• Lean 4
• lake must be installed and available in your PATH.

Installation

Simpleafier is available on PyPI and can be installed using pip.

python -m pip install simpleafier

Usage

To convert all simp calls in a Lean file to simp only:

simpleafier path/to/your/file.lean --simponly

simpleafier must be invoked from the root of your lake project. The lean file provided must be compilable without any errors. simpleafier will create a temporary file in the same directory as the original file for processing. At the end of the process, the temporary file will be deleted and the original file will be replaced with the modified version.
