termenv is a Go library for safely adding colour and styling to terminal output. It detects the terminal’s capabilities and selects compatible ANSI colours and control sequences, avoiding the need to handle escape sequences and colour conversions directly.
The library supports applications running across terminals with different colour capabilities, automatically converting colours to the closest available alternative.
This is free and open source software.

- Converts colours to the closest match supported by the terminal.
- Detects light and dark terminal themes.
- Provides a chainable syntax for combining colours and text styles.

- Offers cursor positioning, screen management and scrolling controls.
- Supports alternate screens, bracketed paste and mouse tracking.
- Can set terminal colours, window titles and cursor visibility.
