Recursion syntax

[cpb]

what’s the correct way to use the *while commands?
with either lists or an integer (as a range)…
Also can each be used with an integer range?

[marcin.kostrzewa]

So for iterating over lists each is the way to go as described earlier.
For integers there’s an upto method generating a range, so you can write things like:

0 . upto 10 . each index:
      doSomething index

As for the real workflow, I like to have the whole body of my loop as a separate function, to be able to write things

list . each myFunc

This is also very nice with the collapse-to-function feature. Just build your flow around the first datapoint, then select the to-be-function nodes, press F and use the newly created function with an each.

tried it with this, no errors, but no results either…

now1 = Time.now
eom = now1.endOfMonth
dd = (eom . format "%d") . toInt
mm = (eom . format "%m") . toInt
yy = (eom . format "%y") . toInt 
wds = 1 . upto dd . each x: 
    (Time.getTimeOfYear yy mm x Nothing) . format "%a"

[marcin.kostrzewa]

I think at this point it’s just a compile error – you probably wanted to use fromTimeOfYear instead of getTimeOfYear in the last line.

[cpb]

same, no result, no visualizer available inside the function, no nodes present In main where the function is called…

@cpb can you paste the whole file here? Or at least the relevant parts? I’m going to need more information to help out with this one.

yep:

import Std.Time
«7»
«26»def getwd wd fol:
    «50»now1 = Time.now
    «51»eom = now1.endOfMonth
    «52»dd = (eom . format "%d") . toInt
    «53»mm = (eom . format "%m") . toInt
    «54»yy = (eom . format "%y") . toInt 
    «55»weds = 1 . upto dd . each x: 
        «56»(Time.fromTimeOfYear yy mm x Nothing) . format "%a"«48»
    weds
«49»
«9»def main:
    «37»weds = getwd "wed" 0
    None

@cpb Okay, this will sound strange, but this file works for me without any changes.

There is a single node inside main and it generates names of consecutive days like so:

If it’s not visible for you, you may try pressing H – maybe it just got in a strange place off-screen?
There aren’t any visualizers inside the getwd function and that’s something we’re working on. For the rule is: if there’s arguments to the function, there’s no visualizations.
However, since the args are not use anyway, you may remove them for now and enjoy the computed values below the nodes.

updated Luna, works now

Awesome, glad to hear that!
