I'm enjoying using ncurses, which work great. Question/bug report
Am I understanding function keyname correctly?
It returns the internal variable name as a string. That is, a
will return the string
But to be useful for a program presenting key prompts to a user,
the programmer would want this function to return a string like "F1".
Related issue, keyname does not seem to use the entries in terminfo
for key labels, eg
etc. (Or, l1=, l2= in termcap). These are described in "Termcap &
book as, e.g., "lf1= The label on the first function key, if
I've written a routine to clean up the returned key labels, but I was
wondering if there's another ncurses function I'm missing, or if
this is the intended behavior, or I this might get changed in the
Incidentally, my routine:
1. Strips off the initial "KEY_"
2. Strip out "(" and ")"
3. If its in the range ([KEY_SBEG .. KEY_SUNDO] (except for
then trim the S and put in place "Shift-".
Thus we get, for example, "F1" rather than "KEY_F(1)", and
"Shift-UNDO" rather than "KEY_SUNDO".
Do you think it would be desirable for keyname to behave more
