Summary

This PR addresses Issue #146 by:

  • Reorganizing the JavaScript codebase into a js/ folder structure
  • Adding a complete Rust translation of the library

Changes

Codebase Reorganization

  • Moved JavaScript source files from src/ to js/src/
  • Updated all import paths in tests and examples
  • Updated package.json exports to point to js/src/

Rust Translation (rust/ folder)

  • Shell Parser (shell_parser.rs): Complete tokenizer and parser supporting &&, ||, ;, |, (), and redirections
  • Utilities (utils.rs): Tracing, command results, ANSI handling, path utilities
  • Virtual Commands: All 21 commands translated:
    • File operations: cat, cp, mv, rm, touch, mkdir, ls
    • Navigation: cd, pwd
    • Text: echo, yes, seq
    • Utilities: sleep, env, which, test, exit, basename, dirname, true, false
  • ProcessRunner (lib.rs): Main execution engine with:
    • Async command execution with tokio
    • Shell detection (Unix/Windows)
    • Virtual command routing
    • Streaming output support
  • Unit Tests: Included with each module

Documentation

  • Added case study in docs/case-studies/issue-146/README.md:
    • Detailed translation patterns (JS async → Rust async)
    • Challenges encountered
    • Lessons learned
    • Architecture comparison

Test Plan

  • JavaScript tests pass with new js/ structure
  • Rust code compiles (pending CI Rust setup)
  • All virtual commands have unit tests
  • Import paths updated correctly in all 400+ example/test files

Notes

  • ESLint warnings in js/src/ are pre-existing and were not introduced by this PR
  • The Rust version is a functional port but may need additional work for full feature parity

Fixes #146

Root ./tests folder is also related to ./js, and Rust version should have its own tests in Rust with the same content.

Ensure all changes are correct, consistent and fully meet the requirements.
