Parsing the node tree

1

I would like to programmatically parse and search the node tree for specific synths.

s.queryAllNodes

This will print the node tree in the post window, but I am having trouble capturing that reply as a string. Any help in this matter is appreciated!

2

My suggestion would be to look at the implementation of queryAllNodes in Server.sc

Apparently it sends an OSC message “/g_dumpTree” to the local server (or “/g_queryTree” for remote server) and then receives the reply via an OSCfunc waiting for a “’/g_queryTree.reply’” OSC message.

Take a look at the NodeSnapshot quark - it does this exact thing.

Hello,

By trying the example in the help of TreeSnapshotView, I’ve got several errors.
Don’t know why exactly…

I just pushed a fix for this, the help should be working now - thanks for the heads up!
You’ll need to do something like this (and recompile) to get the newest:

Quark("https://github.com/scztt/NodeSnapshot.quark.git").update

Many thanks, Scott.
Just for the info, I could not update the Quark via :

Quark(“GitHub - scztt/NodeSnapshot.quark”).update;

WARNING: Quark NodeSnapshot.quark was not installed using git, cannot update.

but it is ok with :

Quark(“NodeSnapshot”).update;

Quark ‘NodeSnapshot’ updated to version: 0.3.2 tag: tags/0.3.2 refspec: tags/0.3.2
