[myhdl-list] Characterstringhandling

[Thomas T. <tho...@de...>]

Here comes an explanation of my bug report about improper character 
string handling.

The following does not work:

	a = Signal(intbv()[8:])
	a.next = "y"
	if a == "n":
		...

IMO should myhdl at least character strings with length of one like an 
integer ( ord(character) ).

I use this charcter handling for a simple command parser.

I have attached a demonstration code and the verilog output - as it 
should be, e.g. is on my installation. I also attached the diff of my 
installation - it is incomplete, but works for my current porposes, 
including conversion to Verilog.

For strings with more than one character things are more difficult...

BTW:
This "//pass" lines in stringbugfunc.v are caused by another simple 
patch to avoid the print-with-more-than-one-argument warning.
