[Qgis-developer] Processing scripts in stand-alone Python scripts

[Victor Olaya]

does Processing.getAlgorithm("script:helloworld") work in a normal
QGIS Python console?

Just in case, the name of the script is the name of the file (without
the extension)

Maybe you can try Processing.alghelp("script") to get the name of
available algorithms from the script provider

Hope this helps
