(sadly editing isn't obvious with the box/non emboss version..) you have to leftclick and drag on the text to be able to select it for editing.. (or ctrl + left double click)

    def draw_buttons(self, context, layout):
        b = layout.box()
        col = b.column(align=True)
        col.prop(self,  "str1", text="", emboss=False)
        col.prop(self,  "str2", text="", emboss=False)
        col.prop(self,  "str3", text="", emboss=False)

zeffii · 2016-12-24T15:40:20Z

@Kosvor2 maybe make

    def process(self):
        v1,v2,v3 = self.inputs
        V1, V2, V3 = v1.sv_get(0), v2.sv_get(0), v3.sv_get(0)
        out = []
        extend = out.extend    # make these available (and makes the code faster )
        append = out.append     
        exec(self.str1+"\n"+self.str2+"\n"+self.str3)
        
        self.outputs[0].sv_set(out)

zeffii · 2016-12-24T15:58:48Z

also i'm using a slightly older version of blender for windows, because of a bug in the windows ID / objects code.. that's why the X isn't there i think?

Kosvor2 · 2016-12-24T18:10:29Z

Yeah, this X is only waste of space in a text box... and no way to turn it off as far as i know.

zeffii · 2016-12-24T18:16:59Z

Would be neat to make the string variables dynamically created, starting out with 3 -- and if user needs more then press + . i'm not sure if it's possible to make a collection / group for Strings .. i have feeling it should be possible..

but that's low priority..

not sure the nesting is working right there.. but that's all for now.

fixed update wrapper, issue with nesting remains..

yeah :)

zeffii · 2016-12-24T21:44:12Z

i quite like this form of exec node, the multi line solution is something that might replace the simpler node-scripts..

Kosvor2 · 2016-12-25T12:10:38Z

https://github.com/nortikin/sverchok/tree/exec_node

zeffii · 2016-12-26T09:20:41Z

might have to include a variety of imports too , some of the math module perhaps

zeffii · 2016-12-26T11:49:15Z

with the dynamic strings I think the iojson code probably needs a dedicated encode/decode part..

iojson doesn't know about propertygroups../ collectionproperty

zeffii · 2016-12-27T18:37:31Z

iojson support added now #1064

The second method avoids IF-ELSE statement within a Process that would make the node slower, so i will use it.

A single if-else statement wouldn't contribute to significant speed fluctuation inside the process function, I wouldn't worry about that.

can add a listener to text editors ctrl+enter operator, to update a current ExecNodeMod straight from text editor too..

Just wondering, with this Multi-Exec, what is the convenient or the special Sverchok functions in the node that allows for wrapping and putting list inside list inside list and stay sane?

We have Script Node already and this one also can be super useful, but not sure where to start? @Kosvor2 Maybe Video tutorial?

@zeffii I like the SN Lite for example and at some point you said it can do "vectorization" and although excited, but I was scared: is this going to be difficult?

@enzyme69 snlite can already to vectorization, the snlite thread has examples.

but I was scared: is this going to be difficult?

jimmy, its difficulty is going to be directly proportional to your level of python-fu. But as it stands I think it's about as simple as it gets for snlite, maybe as it will ever get for code-based vectorization.

Ok, interesting, in that case I'll do. Feels motivated!

before you go nuts on snlite, it's still beta. consider it broken ( but it works for my needs ) .

*reloading a .blend still doesn't pick up 'current' param values, * but this thread is not the place to talk about snlite.
