Blessed is a thin, practical wrapper around terminal capabilities in Python.
Blessed is a more simplified wrapper around curses, providing :
- 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_
- 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
Blessed does not provide...
- Windows command prompt support. A PDCurses_ build of python for windows
provides only partial support at this time -- there are plans to merge with
the ansi module in concert with colorama to resolve this.
