get comment or message box content within a js ?
I would need to get (and set) the content of (named) comment and message box within a js.
is it possible ?
couldn’t find info about it in the doc.
any help is very welcome !
thanks in advance
Setting is as easy as sending a message to the named object with the set or message functions, but retrieving the current information is much more difficult. One idea is to script a [grab] object into place and connect it to a [message] box and back to a dedicated inlet of your [js] object. If you only need this to work in a patching environment you can even parse the JSON text of your patch as demonstrated in this article. However this won’t work with anything other than a maxpat file so if you need it to function in a standalone application this method will not work.
Thanks Luke for your reply.
unfortunately, this won’t help me much, because i need to get the content of a comment box, and grab can’t get it ; (and my js isn’t in the same patch…)
ok, I’ll find a workaround !
Mathieu, did you ever resolve this issue? I am trying to do something similar, retrieving the text of a comment box with JS. Any info of your process or solution would be appreciated!
no, sorry, I never found a solution, and finally had to give up retrieving content of comment box.
One way to do this is to load up the patcher as JSON and then parse it for comment boxes.
Please excuse the roughly hacked out code – hopefully you will get the idea
var patcher_file = new File(this.patcher.filepath);
while (patcher_file.position != patcher_file.eof)
lines += patcher_file.readline();
var parsed_patcher = JSON.parse(lines);
if (parsed_patcher["patcher"]["boxes"]["box"]["maxclass"] === "comment")
