Improve Vedic CLI Tooling, Add Pre-commit Hooks, and Format Codebase

[PtPrashantTripathi]

This PR includes a series of enhancements and refactors aimed at improving the development workflow, code quality, and CLI tooling for the vedic project. Key areas of focus include:

• CLI refactoring for reliability and usability
• Pre-commit hook integration (Black, isort, pyupgrade, etc.)
• Auto-formatting and code cleanup (Python and Rust)
• Git diff/patch tooling support

Key Changes

CLI Improvements (tools/cli.py)

• Refactored the CLI for clarity, modularity, and correctness

• Fixed malformed argparse argument definitions

• Added:

  • Clear-screen command (cross-platform)
  • Rust tool checks (cargo, wasm-pack, pre-commit)
  • Format command that runs cargo fmt and pre-commit
  • --verbose mode with unified logging

• Improved subprocess handling and output

Code Formatting and Cleanup

• Applied Black, isort, and pyupgrade on all Python files
• Fixed inconsistent import orders and trailing whitespace
• Renamed or removed unused variables where appropriate
• Ran cargo fmt on Rust code for consistent formatting

Pre-commit Integration

• Added .pre-commit-config.yaml with:

  • black, isort, pyupgrade
  • YAML, JSON, TOML validators
  • Trailing whitespace + newline fixers

• Hook autoupdate metadata included (autoupdate_schedule, commit_msg)

• Configured Python hooks to run using Python 3

Git Utilities

• Documented and tested commands for:

  • Viewing staged diffs: git diff --cached --color-words
  • Creating patch files for unstaged changes
  • Setting file executable bits recursively and cleanly:
    chmod -x $(find tests/ -type f)
git add --chmod=-x $(find tests/ -type f)

---

How to Test

1. Run: python tools/cli.py --help to check all CLI options
2. Run: python tools/cli.py -f to format and run hooks
3. Ensure pre-commit run --all-files succeeds

Dependencies

• Pre-commit should be installed:
  pip install pre-commit

• Rust environment tools required:

  • cargo, rustc, wasm-pack
