Flow Scripts

Creating a Script

Each script must have the following a starting comment block describing the script and a Script function that will be the entry point of the script.

Script Comment Block

/**
 * Requires a 7Zip tool to be configured and will zip files
 * @author John Andrews
 * @version 0.6.1.900
 * @param {string} ArchiveFile The name of the zip file to create, if empty a random name will be used
 * @param {string} Pattern The filename pattern to use, eg *.txt
 * @param {bool} SetWorkingFileToZip If the working file in the flow should be set to the newly created zip file
 * @output Zip file created
 */

• The text before the first @ is the description of the Script
• @author [optional] and it is the person who created the script
• @version [optional] the version of the script
• @param {type} [name][description]
  • Type: tells the UI what type of input this is, available options are "string", "bool", "int"
  • Name: The variable name passed in to the function, no spaces are allowed
  • Description: everything after name
• @output these the possible output connections this function has. The order is import, the first @ouput will be "Output 1", 2nd will be "Output 2" etc.

Entry Point

• The script must have a "Script" function as the entry point
• The script will have the variables defined in the comments passed into the script when called

function Script(ArchiveFile, Pattern, SetWorkingFileToZip)

    return -1;
    }

    if(SetWorkingFileToZip)
    Flow.SetWorkingFile(output);
    return 1;
