Re: [PD] Abstraction arguments: tell apart symbols from floats from no argument at all
unfortunately, this doesn't work. missing arguments will become 0 and therefore can't be differentiated from a float arg with with the same value. I think it's only dollarsyms (e.g. "_$1") where the missing argument doesn't become 0. I think Pd vanilla really needs a mechanism to retreive the creation arguments as a list. personally I quite like $@. > Gesendet: Samstag, 22.

Re: [PD] Abstraction arguments: tell apart symbols from floats from no argument at all
another way to do it might be the following. I don't have now the time to test it: - loadbang a list with all the arguments (maybe initiated by something like [list $1 $2 $3 ... $16 or whatever]) - use an abstraction from list-abs to drip the list - send the output through a route to test the type If you know beforehand that 0s won't be part of the arguments, it will be even easier, just filter out the 0s when detecting the argument type. * Christof Ressi [2018-12-22 17:15]: if you're ok with externals you can also use [dollarg] from iemlib or [canvasargs] from iemguts. for a hacky vanilla solution, see attached patch.

if you're ok with externals you can also use [dollarg] from iemlib or [canvasargs] from iemguts. for a hacky vanilla solution, see attached patch.

[PD] Abstraction arguments: tell apart symbols from floats from no argument at all
Hi list, please excuse me if this has been discussed numerous times, but the search engine at https://lists.puredata.info/pipermail/pd-list/ does not give me reasonable answers. I am writing an abstraction and for one of its numeric arguments I would like to detect if it has been not specified, or if it has been set to a float including 0. How can I do this? I would also like to detect if another argument is a float or a symbol and process these two differently without causing Pd error messages. Is this possible? Thank you!
