I found this simple piece of js code, allowing to retrieve parentpatcher of a file.

What I need though is the highest parentpatcher (i.e. the main patcher, whatever it is, whatever it contains)

I know that if I keep nesting parentpatcher methods manually (parentpatcher.parentpatcher.parentpatcher.....)

I eventually find that name, but if I go too far I come up with an error I don't know how to handle.

js: NameFile.js: Javascript TypeError: this.patcher.parentpatcher.parentpatcher.parentpatcher.parentpatcher.parentpatcher is null, line 11

Any suggestions? Is there a way to nest object methods like this in a recursive way?

Apparently I lack the js vocabulary to find this on google :'(

Hi,

Salut Julien,
Quelque chose comme cela ?

if (this.patcher.parentpatcher)
    	outlet(0, this.patcher.parentpatcher.name);

Salut Jean-François ! (I continue in English :)

My question would be that if my subpatch is on level n, I'm able to retrieve the name of the main patch whatever n is.

if (this.patcher.parentpatcher.parentpatcher)

this.patcher.parentpatcher.parentpatcher.name

basically I can retrieve the main patch (level 0) name in levels 1 and 2,

but in level 3 I start getting the name of level 1, etc.

I can keep nesting else if expressions forever by hand but that's not really satisfying for me 😂

What I need is a way to append ".parentpatcher" recursively until level 0 is found. Does it make sense?

You could have a look at the applydeep method for thispatcher. Check out Leafcutter's patch on this thread: https://cycling74.com/forums/patch-hierarchy-viewtree

But that's pretty much the exact opposite of what I need, 

since applydeep dives in subpatchers, not higher :(

OK, I did what I should have done first: look at the patcher object's documentation.

Check out the "box" property, there lies a piece of code allowing you to get the top-level patcher's name...

Actually the API changed a little, it didn't work until I found this :

OOOOH thank you Jean-François !
I should have RTFM indeed...

Highest parentpatcher?
