restructure-solutions

Restructuring a Lean file with multiple solution variants isolates each solution into a self-contained group with Implementation, Tests, and Verification sections. The tool automatically numbers these sections when multiple solutions exist, while preserving top-of-file imports, opens, and options for easier maintenance.

Organizing Lean4 code for testing preserves existing imports, opens, and options at the top of the file. Helper lemmas are kept in the first Verification section where they are initially needed, ensuring each restructured solution group remains valid and self-contained for verification.

Separating multiple Lean solutions in a single file for independent verification involves breaking down a single problem's variants (e.g., solution, solution') into dedicated section groups. Each group receives its own Implementation, Tests, and Verification blocks, maintaining the original Prompt section at the end for reference.

This refactoring tool can process single-solution Lean files, but its core numbering and grouping logic is designed for files with multiple variants. It will reorganize the file structure while preserving imports, options, and the final Prompt section, though automatic section numbering primarily targets multiple solution sets.

Lean code reorganization keeps the Prompt section at the end of the file to preserve the original problem context for reference. This ensures the restructured solution variants, now separated into Implementation, Tests, and Verification groups, remain connected to their original problem statement.

You need to restructure Lean solution files for code organization when a single human-eval problem contains multiple solution variants that are difficult to test or maintain. Restructuring isolates each variant into self-contained section groups, enabling easier independent verification and cleaner code organization.
