Re: [PD] What is the purpose of iemgui_raute2dollar

[Miller Puckette]

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.

Re: [PD] What is the purpose of iemgui_raute2dollar

[Ivica Bukvic]

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.

Doesn't m_binbuf.c have a full set of functions to handle that for you?

What's the problem with simply backslashing the dollar sign before sending 
the message to Pd?
