| 9 | +I'm having some trouble with either of the line editing libraries available |
| 10 | +to me. If I build Python with libreadline, I get "staircases" in my |
| 11 | +interpreter output: |
| 12 | + |
| 13 | + >>> s = 1 |
| 14 | + >>> a = 3 |
| 15 | + >>> etc. |
| 16 | + |
| 17 | +So I figured I'd give Rich Salz's editline a try. It seems to be missing a |
| 18 | +couple readline functions. When I link I get: |
| 19 | + |
| 20 | + myreadline.o: Undefined symbol _rl_insert referenced from text segment |
| 21 | + myreadline.o: Undefined symbol _rl_bind_key referenced from text segment |
| 22 | + |
| 23 | +I'm running on BSD/OS 2.0 with GCC 2.6.3 as the compiler. My configure line |
| 24 | +was |
| 25 | + |
| 26 | + ./configure --with-readline=/home/dolphin/skip/src/editline \ |
| 27 | + --with-dl-dld=/home/dolphin/skip/src/dl-dld,/home/dolphin/skip/src/dld |
| 28 | + |
| 29 | +For editline I tried several things before arriving at something that does |
| 30 | +work ... sort of. First I commented out the tab key binding in Python's |
| 31 | +Parser/myreadline.c then had to fiddle with editline.c to get tabs to |
| 32 | +insert. The diffs below seem to work, but have no notion of tab stops (I |
| 33 | +like 4-char tab stops). |
| 34 | + |
| 35 | +I'd be grateful if anybody had a solution to the readline staircases or a |
| 36 | +better solution for making editline work. |
