numd 0.3.0

Breaking Changes

• Simplified configuration API: Replaced --config-path (YAML) with --eval flag that accepts inline Nushell code or sourced .nu files

  # Before: numd run file.md --config-path config.yaml
  # After:
  numd run file.md --eval '$env.numd.table-width = 80'
  numd run file.md --eval (open -r numd_config.nu)

• Removed flags: --result-md-path, --save-ansi, --no-backup, --no-save (simplified API)
• Renamed test commands: testing → test, testing-unit → test-unit, testing-integration → test-integration

New Features

• Reproducible output by default: Runs intermediate scripts with nu -n (no config files) for consistent output across systems. Use --use-host-config to load host environment when needed
• Git safety check: Errors on uncommitted changes before overwriting. Use --ignore-git-check to bypass
• CI support: Added --fail flag to toolkit.nu test for non-zero exit on test failures
• Test update mode: Added --update flag to automatically stage changed integration test files
• Plumbing commands: New low-level composable commands in numd/plumbing.nu:
  • parse-file, strip-outputs, execute-blocks, to-markdown, to-numd-script
• Command examples: Added @example attributes to commands for better discoverability

Bug Fixes

• Fixed clear-outputs without --echo creating empty files
• Fixed $env.numd fields being overwritten instead of merged in config loading

Improvements

• Standardized terminology to "fence options" throughout codebase
• Reorganized module structure: moved capture and parse-help to separate files
• --echo now outputs only markdown without stats for cleaner piping
• Added pipe-to helper for cleaner pipeline generation
• Added unit tests for plumbing commands using nutest framework

CI/Infrastructure

• Added Windows testing to GitHub Actions
• Improved workflow with git diff reporting after integration tests
