Forgot to include pd-list and l2ork-dev list...

So, I am about to commit a 'fix' in pd-l2ork where one can now have labels (for gatoms and arrays as well) where escaped $ is converted into ASCII 0x01 (SOH). This seems to side-step the issue for the time-being. Does this affect other objects?
The ideal fix would be using negative ascii values (e.g. -0x80) but those don't seem to cut the mustard once they are received by tcl/tk...
Best,

This does need fixing... it's a primitive escaping mechanism which needs to be replaced with a "correct" one. Unfortunately there are various places in the code that escape stuff in various ways (to get strings past the TCL parser or the Pd parser) and it's never been thought about in a unified way.

Right, but this function does not do that, it explicitly replaces # with

What does # have to do with anything? Are you saying # is being
substituted
for $ to preserve it? Even so, this still makes no sense because if you create an iemgui object (pick one), then add a label with only a "#" in
it.
Once you click apply, you get $ on the label instead. Reopening
properties
provides you with a label that is equal to $, so this sounds like a bug
to
me that does some sort of one-way mangling that needs to be fixed and
more
so, it seems to me there should be a different ascii character used to preserve $, one that does not exist in the regular text-based ascii chars... e.g. in pd-l2ork we use \t to substitute for \n and thus
preserve
endlines in comments and other places.

Because Pd's parser is likely to eat up a "$" followed by a number as a banking fee to pay the cost of sending messages. :)
Send this from the GUI: (canvas_addy) obj 0 0 clip $1 $2
and it becomes this in Pd: [clip 0 0]
There's also sys_decodeddialog/sys_encodedialog that is used for canvas_find.
Additionally, I think you may have added another parser inside s_main to separate filenames in Pd-l2ork (although that one doesn't have
anything
to do with dollarsigns).
I have not yet decided where I want to add my own parser for the GUI
port.
I think a Pratt parser for message-box math would be neat.

I presume this may pertain primarily to IOhannes and Miller,
I am trying to figure out what is the purpose of raute2dollar in iemgui objects? On an obvious level the function replaces # with an $ in a
send,
receive, and label symbols. Why is this necessary? Personally, I cannot think of a reason why it would be, but then again, I may very well be missing something...
