yachalk is a feature-complete clone of the Chalk (JavaScript) library.
Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
This is free and open source software.
Key Features
- Fluent, auto-complete-friendly API for maximum coding efficiency.
- Ability to nest styles.
- Proper handling of styling edge cases (same test cases as Chalk).
- Auto-detection of terminal color capabilities.
- 256/Truecolor color support, with fallback to basic colors depending on capabilities.
- Same conventions as Chalk to manually control color modes via FORCE_COLOR.
- No dependencies.
- Fully typed (mypy strict), no stubs required.
