//JW Lua// can be user configured to send specific parameters to the script. The user handles the parameters from JW Lua's //Manager// and the parameters will then be sent to the script both from JW Lua's //Explorer//, Finale's plug-in menu or in a //Group Script//. Script Parameters are optional.

==== Setting the Definition ====

//JW Lua// must know if the plug-in can handle parameters. This is done in the plug-in definition.

{{:wiki:jwlua:scriptparameterssetup.png?nolink|}}

Put each info parameter on a separate line. The syntax is almost identical to [[jwlua:uservalueinput|finenv.UserInputValue() dialog boxes]], except that there's generally no quotation marks around the strings and no ''{}'' around lists.

//Lists// (except for ''NumberedList'' items) and //init values// are optional for parameters. 
==== Handle Parameter in the Script ====

A few lines of code are required to handle parameters sent to the script. Always make sure that the script can run without sent parameters as well.

<code lua>-- Default values, if no parameters were sent to the script
local resizestyle = 2
local relativeresize = true

-- Check if parameters were sent to the script.
-- If that's the case, use those values instead.
local parameters = {...}
if parameters[1] then resizestyle = parameters[1] end
if parameters[2] then relativeresize = parameters[2] end</code>
