Jansi is a small Java library that enables ANSI escape sequences for formatting console output, working even on Windows via bundled JNI libraries. It abstracts terminal capabilities, passing through, filtering, or emulating ANSI codes depending on the platform and output target.
Use cases
- print colored console output in java on windows
- strip ansi escape codes when output is redirected to a file
- format terminal text with colors in a java cli app
- access low-level console apis from java via jni
- make system.out support ansi sequences cross-platform
When to choose
- you need ANSI colors in Java console output on Windows or redirected streams
- you want a tiny dependency with an easy Ansi builder API
When to avoid
- starting a new project - the library is unmaintained and merged into org.jline:jansi
- you need full terminal interaction features rather than just output formatting
