How do you do that ?
DD has sys_mgui(), which operates at a level similar to
binbuf_addv(), but constructs Tcl function calls. It still called
sys_vgui() under the hood. However, if sys_vgui() had been
completely replaced by sys_mgui(), then it would have become easy to
replace that Tcl eval-based protocol by, for example, OSC-over-TCP.
But what do _you_ have in mind, specifically ?
Here's a good example of what I mean: the drawing commands for
obj,msg, etc boxes should not be in 'pd'. 'pd' should tell 'pd-gui':
"draw an object on this canvas, at this x,y with these inlets and
outlets". "pd-gui" should also handle the mouse clicks, selection
coloration, change of line style from dashed to solid, etc. So
something like:
draw_object .x230ad0.c "osc~ 500" 10 500 inlet~ inlet outlet~
That would replace this block of raw Tcl:
