Peon works for you while you are developing.

It runs any command you tell it and execute the command when some file that matches a pattern is changed.

Just install using:

python setup.py install

You can install from pip:

pip install peon

If you intend using this in Mac, you need to install py-Growl for Growl Notification

To use Growl, you need to configure him to allow listening incoming notification (Network)

By default Peon looks for changes in python files (*.py) and if no command is specified, it run nosetests.

Peon will keep running that command whenever a file changes.

For example, take the following directory tree as example:

.
|-- Makefile
|-- peon
|   |-- __init__.py
|   |-- peon.py
|   |-- stop.png
|   `-- tick.png
|-- setup.py
`-- tests
    |-- base.py
    |-- checksum_spec.py
    |-- something_has_changed_spec.py

If I want Peon watches for changes in all my "*.py" files and run "make" when something changes, I could do simply:

$ peon make # run make in the current dir, looking for changes in *.py files

It is possible to specify the directory to watch (-d or --directory option):

$ peon make -d peon

It is possible to tell peon what is your pattern too, through -p or --patern option:

$ peon make -p '*.png' -d peon

If you do not want peon to reset/clear your terminal before each run, you may use the --no-reset option:

$ peon make --no-reset
