retrieve an extensions textbox input as a list?

Postby draftman » Wed Jun 01, 2016 8:23 am

Is it possible to retrieve an extensions textbox input as a list?
Tried this and got this error ,( ValueError: invalid literal for int() with base 10: '6 , 2').

inx

Code: Select all

<param name=" List " type="string"  _gui-text=" List ">0</param>



py

Code: Select all

        self.OptionParser.add_option("--List",
                        action="store", type="string",
                        dest="List ", default="0",
                        help="i need it")

                width = [self.options.List]
                W = int(width[0]) * 22.5

Well, you could either use two (or more) float boxes in your .inx file: good and safe, only useful if the number of inputs is limited (looks like you're asking for width and height, so ...)

or you could do
your_list = your_string.split(separator)

on the string you got (but if a user enters something weird, then it won't work): only useful if the number of list items is not bounded, because it's more or less error prone, so will need some good exception handling. See also: https://docs.python.org/2/library/stdty ... #str.split

Or you might be looking for eval() or some json format. At least eval() is a 'dangerous' option, too, and you should have good error handling in place.

Thanks, Moini.
I did not know about split. Looks very useful.
I'll have to give it a try and see how it works.
