==================================

Butch - The free Batch interpreter

==================================



.. |butch| replace:: Butch Coolidge

.. _butch: https://pulpfiction.fandom.com/wiki/Butch_Coolidge



Named after the famous Pulp Fiction boxer |butch|_ from Tennessee.



* Chat: ``__

How to run

**********



Installation

============



.. code::



   pip install butch



Post-Installation

-----------------



.. |sitepkgs| replace:: ``site.getsitepackages()``

.. _sitepkgs: https://docs.python.org/3/library/site.html#site.getsitepackages



Make sure to run the test suite after the installation to verify everything

works as it should. The test suite is included in the package itself, so it

should be located in the first ``site-packages`` folder found via |sitepkgs|_.



.. code::



   python -m unittest discover \

       $(python -c "import site;print(site.getsitepackages()[0])")/butch



Development

-----------



Get the latest version:



.. code::



   pip install https://github.com/KeyWeeUsr/butch/zipball/master



Running

=======



Butch is available as a standalone executable as well as a Python module,

therefore it can be invoked by any of these commands if installed properly::



   butch

   python -m butch



which will launch the REPL (console) directly.



Use ``butch /C "echo Hello, Batch"`` for interpreting a Batch command from a

string or use ``butch /C hello.bat`` to run Batch from a file.



Use ``/K`` switch instead of ``/C`` to jump into the console after a command or

a file finishes.



Use ``butch /h`` to display help for other switches.
