macal 3.0.5

Specialized scripting language

Macal Package

This is the installation package for Macal, a Python script Language by Marco Caspers.

Macal was developed for a limited and specific use.

Creating a human and machine readable configuration file that loads data, transforms the data and emits the data. Loading happens by calling functions from libraries specific to a particular (Rest/XML) API.

Emitting data is currently limited to the console and SysLog.

In the tests folder find the test.py utility that contains several tests.
