Progress and status updates on terminals
========================================
`ttystatus` is a Python library for showing progress reporting and status
updates on terminals, for (Unix) command line programs. Output is
automatically adapted to the width of the terminal: truncated if it does
not fit, and re-sized if the terminal size changes.
Output is provided via widgets. Each widgets formats some data into
a suitable form for output. It gets the data either via its initializer,
or from key/value pairs maintained by the master object. The values are
set by the user. Every time a value is updated, widgets get updated
(although the terminal is only updated every so often to give user time
to actually read the output).
The output from ttystatus goes to the terminal (`/dev/tty`) and is
restricted to a single line.
See example.py for an example of how to use the library.
Installation
------------
* Use Python distutils (setup.py) as usual.
* If possible, use the Debian packaging when you can.
You will need some other stuff to run automatic tests:
* http://liw.fi/coverage-test-runner/ for unit tests.
Hacking
-------
See <http://liw.fi/ttystatus/> for information about version control
trees, etc.
Run `./check` for unit tests. If you make any changes, run it
first, and don't stop fixing things until coverage is 100% again.
If you do make any improvements, I would welcome patches. Send me
(see http://liw.fi/contact/ for details) a patch, a bzr bundle, or
a link to a bzr branch I can merge from. Thanks!

See also
--------
* http://pypi.python.org/pypi/progressbar/ is another library for this.
It is older and more well-established, but, I think, a bit less
flexible. For example, it seems to assume there is only one percentage
value that gets reported.
