Having a bit of trouble here with the color formatting. The
BPythonFormatter works (mostly, had to fix it up a bit) but there's
another issue.
When Oranj prints error messages, it'd be nice if they were colored.
They already are when using the console, but I need to use the curses
color codes for printing in the bpython.
What I'm doing is this:
msg = "\x01r\x03%s\x01d\x03%s" % (type(e).__name__, ("" if not e.args
else (": " + " ".join(map(str, e.args)))))
Ideally, this should make the first bit (type(e).__name__) red and the
other bit normal gray colored (Its the error message). This isn't
working, however - the entire line is red.
Anything I'm doing wrong? I could send complete, (sorta) working code
if you want, but in any case, is there anything obviously wrong?
