on Ubuntu 18.04.
What is python-blessed
python-blessed is:
Blessed is a thin, practical wrapper around terminal capabilities in Python. It provides:
- Styles, color, and maybe a little positioning without necessarily clearing the whole screen first.
- Works great with standard Python string formatting.
- Provides up-to-the-moment terminal height and width, so you can respond to terminal size changes.
- Avoids making a mess if the output gets piped to a non-terminal: outputs to any file-like object such as StringIO, files, or pipes.
- Uses the terminfo(5) database so it works with any terminal type and supports any terminal capability: No more C-like calls to tigetstr and tparm.
- Keeps a minimum of internal state, so you can feel free to mix and match with calls to curses or whatever other terminal libraries you like.
- Provides plenty of context managers to safely express terminal modes, automatically restoring the terminal to a safe state on exit.
- Act intelligently when somebody redirects your output to a file, omitting all of the terminal sequences such as styling, colors, or positioning. Dead-simple keyboard handling: safely decoding unicode input in your system’s preferred locale and supports application/arrow keys.
- Allows the printable length of strings containing sequences to be determined.
