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.

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. + +*** editline.c~ Tue Nov 15 08:53:01 1994 +--- editline.c Sun Nov 19 09:15:16 1995 +*************** +*** 142,145 **** +--- 142,148 ---- + TTYput('?'); + } ++ else if (c == '\t') { ++ TTYput('\t'); ++ } + else if (ISCTL(c)) { + TTYput('^'); +*************** +*** 1326,1329 **** +--- 1329,1338 ---- + } + ++ STATIC STATUS ++ tab() ++ { ++ return insert_char('\t'); ++ } ++ + STATIC KEYMAP Map[33] = { + { CTL('@'), ring_bell }, +*************** +*** 1335,1339 **** + { CTL('G'), ring_bell }, + { CTL('H'), bk_del_char }, +! { CTL('I'), c_complete }, + { CTL('J'), accept_line }, + { CTL('K'), kill_line }, +--- 1344,1348 ---- + { CTL('G'), ring_bell }, + { CTL('H'), bk_del_char }, +! { CTL('I'), tab }, + { CTL('J'), accept_line }, + { CTL('K'), kill_line }, +-- +Skip Montanaro skip@automatrix.com (518)372-5583 +Musi-Cal: http://www.calendar.com/concerts/ or mailto:concerts@calendar.com +Internet Conference Calendar: http://www.calendar.com/conferences/ + >>> ZLDF: http://www.netresponse.com/zldf <<< |
