Fields

Field	Type	Required	Description
description General	string		describe this step.
condition General	lua-expression (string)		Expression evaluated before anything else; when it returns false neither the optional run logic nor any let pairs execute for that event. Examples: 2 * count()
overwrite Output	boolean (bool)		Overwrite a field if it already exists.
let Script	map (string)		field-expression pairs, evaluated sequentially after the optional run snippet; each expression sees fields created earlier in the list.
load Runtime	path (string)		Load a file containing Lua functions into the current context ‘init.lua’ is loaded by default. Examples: /path/to/file, c:\users\joe\data\file.txt
run Script	multiline-text (string)		Per-event logic executed after the condition passes but before the let pairs run; it can set up state but no longer short-circuits the lets.
