I'm having some trouble with either of the line editing libraries available
|
|
to me. If I build Python with libreadline, I get "staircases" in my
|
|
interpreter output:
|
|
|
|
>>> s = 1
|
|
>>> a = 3
|
|
>>> etc.
|
|
|
|
So I figured I'd give Rich Salz's editline a try. It seems to be missing a
|
|
couple readline functions. When I link I get:
|
|
|
|
myreadline.o: Undefined symbol _rl_insert referenced from text segment
|
|
myreadline.o: Undefined symbol _rl_bind_key referenced from text segment
|
|
|
|
I'm running on BSD/OS 2.0 with GCC 2.6.3 as the compiler. My configure line
|
|
was
|
|
|
|
./configure --with-readline=/home/dolphin/skip/src/editline \
|
|
--with-dl-dld=/home/dolphin/skip/src/dl-dld,/home/dolphin/skip/src/dld
|
|
|
|
For editline I tried several things before arriving at something that does
|
|
work ... sort of. First I commented out the tab key binding in Python's
|
|
Parser/myreadline.c then had to fiddle with editline.c to get tabs to
|
|
insert. The diffs below seem to work, but have no notion of tab stops (I
|
|
like 4-char tab stops).
|
|
|
|
I'd be grateful if anybody had a solution to the readline staircases or a
|
|
better solution for making editline work.
