Pyth

Pyth, an extremely concise language.

Installing Pyth

On Windows, add %APPDATA%\Python\Scripts to your PATH. On linux add ~/.local/bin/ to your PATH.

Then, to install or update Pyth as a user from PyPi, use:

pip3 install --user --upgrade pyth-lang

To use the latest development version:

git clone https://github.com/orlp/pyth5
cd pyth5
pip3 install --user --upgrade .

If you want to help develop Pyth, install the package as editable, so your changes become active immediately:

git clone https://github.com/orlp/pyth5
cd pyth5
pip3 install --user --editable .

For all of the above, to uninstall Pyth run:

pip3 uninstall pyth-lang

Using Pyth

Pyth is invoked using the pyth command. Use pyth --help to see its usage.

To run the Pyth testsuite run python3 -m unittest from the source directory, or python3 -m unittest pyth_lang.test from anywhere. You can run only the tests for, say, + by running python3 -m unittest pyth_lang.test.Add.

Or even better, use nose (pip3 install nose) and run nosetests. nose has all kinds of amazing plugins and tools, for example if you install Ned Batchelder’s coverage plugin (pip3 install coverage) and run nosetests --with-coverage you get a code coverage summary for the testsuite.
