Thanks Hans, this looks good and seems to be a similar way than the one
proposed by Christof.

a small trick I learned the last days - if you use coords
instead of donecanvasdialog, it won't trigger the edit mode
issue in vanilla. For the parameters you use, it should work.

I could leave a couple of theoretical suggestions:
- one disadvantage of data-s is that to move the marker, it's
necessary to drag it from one of its corners. A click in a blank
space won't have any effect. This might be circumvented using
[mousestate] or a similar external, but it won't be vanilla code
anymore.
- it's a pity that the variable limits in a struct can't be
themselves assigned to variables. It's still not possible to
reduce the size of the canvas but have different boundaries for
the square. I guess a dynamically-created template would be an
idea, but I didn't try with it yet.

Best,

Joao

See [touch] in droidparty abstractions which is built using
data structures.. I've been working with it for a while.

Hi list,

what's the current recommendation for a simple x-y Pd GUI
controller
type of thing? Like a slider but horizontal and vertical.
There are probably a few externals providing this, which
one is the
best/most compatible/future proof?
In vanilla this can be emulated with an object reporting
its position on
a canvas, but to use it one must change to the edit mode
which is kind
of counter-intuitive.

Anything I'm missing?

i have this vanilla abstraction based on a patch by johannes, which gives 1 for

maybe thats for you?

Re: [PD] Abstraction arguments: tell apart symbols from floats from no argument at all

[Christof Ressi]

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 $@.

Re: [PD] Abstraction arguments: tell apart symbols from floats from no argument at all

[João Pais]

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. I'm sure there are more ways, this is just one that I remembered.

And it is a nice one, Thanks Christof!

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. 
I'm sure there are more ways, this is just one that I remembered.

If you're ok with using an external library, then there is [pofutil] in the pof 
library which outputs a list of arguments when sent a [dollarg( message.
 
so, like:

[dollarg(
|
[pofutil]
 
You can then just use pd's list functions (list length, list split, etc) to 
pull that list apart and check its length, etc. 
 
[route symbol float] should do the last bit you wanted,

[PD] Abstraction arguments: tell apart symbols from floats from no argument at all

[Peter P.]

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!
P
