Using Scripts
Scripts can be used to perform various operations, such as to manipulate data, for example.
PlanetPress Workflow can perform scripts written in four different scripting languages and also
provides an interface for editing scripts.
Warning
While this chapter provides some very useful and detailed information about scripting
within PlanetPress Workflow, its focus is to inform you about the features, variables and
functions unique to this environment. This chapter assumes that you have a working
knowledge of the scripting language you wish to use and does not purport to teaching
you anything about this language that you don't already know. Learning any of these
language is beyond the scope of this documentation.
Languages
There are four scripting languages available through the Run Script task: JavaScript, VBScript,
Python and Perl. Each language has its own strengths and weaknesses which we will not
cover in this documentation. While VBScript is the most used language at the moment, the
examples provided in this chapter are presented in all supported languages.
By default, the Run Script task expects VBScript. You can select another language via the
Language menu in the Script Editor that opens when you add the Run Script task to a process.
You can also set another language as the default for the Run Script task, in the Workflow
preferences (go to Behavior > Default Configuration).
Note
While JavaScript and VBScript are natively available on Windows operating systems.
Python and Perl require third-party tools to be functional. For Perl, ActivePerl can be
installed. For Python ActivePython (version 2.7.13 ) can be installed.
