ScriptForge - (scriptforge.py) Python-Basic machinery
Python scripts can now invoke usual Basic builtin functions
Example:
from ScriptForge import CreateScriptService
bas = CreateScriptService('Basic')
bas.MsgBox('This is the text to be displayed', bas.MB_ICONEXCLAMATION)
Python scripts can use most ScriptForge services written in Basic
Example:
from scriptforge import CreateScriptService
FSO = CreateScriptService('FileSystem')
a = FSO.BuildPath('/tmp', 'xyz')
Syntax and semantic are as close as possible to the Basic syntax
Implemented are a SFServices class and its subclasses representing each
a ScriptForge service and where the interfaces are defined (properties,
methods and arguments)
Their execution goes through the "machinery", i.e. a set of python
and basic routines that manage the call from the python process to
the appropriate service in an as much agnostic and generic way
Only a limited set of services are implemented so far: SF_FileSystem
(partially) and SF_Timer: they served as prototypes and initial tests
