Thank you Marcus I'll give it a try :)

Hi George,

you could go into gnuradio/grc/blocks, change parameter.xml to have

		<option>
			<name>Boolean</name>
			<key>bool</key>
			<opt>type:bool</opt>
		</option>

and then change grc/core/generator/flow_graph.tmpl and in the

    #for $param in $parameters

loop add an if type == "bool": clause that adds a binary option (something with ..action="" see [1]). great chance to contribute :) .

Alternatively, just use an int parameter, and use bool(parameter_id) whereever you need a true or false. You'll have to pass 0 for False, and any other int for True, then.

Best regards,

Marcus

Hi all!

I need to give the user the option to pass a boolean parameter when executing my script from command line, something like '--split-image=True', where split_image is a parameter of a block. What is the way to do that from gnuradio without needing to translate inside my code the 'True' string to the boolean True? The 'parameter' block in gnuradio does not support boolean type as i saw...

Thank you!
