I got it a bit mixed up the first time, -lib and -stdlib change the canvas-local path, and -path and -stdpath change the global path. According to the C code, that is what it does. Check out canvas_declare(), starting at line 1478: http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/pd/src/ g_canvas.c?view=markup This means append to the canvas-local search path(e->ce_path): e->ce_path = namelist_append(e->ce_path, strbuf, 0); .hc > >> Tcl has namespaces that can be used across procedure/class, provided >> you import them into procedure/class.
