- I got the pd-ksh from John MacMillan after he indicated that he
- had a version of it that had vi editing (I'd seen various versions
- with emacs-editing, but none with vi).
-
- It had a few bugs and areas which were not quite complete. I fixed
- (or at least tried) to fix several; there are still some things
- which I plan on doing (or at least looking into).
-
- Bugs fixed (or at least abated):
-
- vi-mode changes:
- - Changed memcpy() to memmove(), which fixed the trashing of
- the end of the edit buffer while inserting in the middle
- of a line or with use of '#'
- - using 'r' replacing the current character with ^@
- - typing ctrl-c resulting in next command being garbled
- - lack of support for '-' and '+' (pretty trivial)
- - finish adding support for '*' (not entirely sure I'm freeing
- malloc'ed memory correctly here, but I haven't had any problems)
- - treats '_' as end of a word
-
- general changes:
- - reporting "not found" when a file actually doesn't have
- the appropriate execute bit set (now says "cannot execute"
- or "not found", as appropriate)
-
-
- Still to do:
-
- vi changes:
- - fix ctrl-r (I've come up with a hack, but it involves
- redrawing the screen a lot when it isn't necessary; I
- really wouldn't consider this a fix)
- - add support for 'v'
-
- general changes:
- - seems to be a memory leak when executing shells in the
- current shell; repeatedly executing ". /etc/profile"
- increased the size of the program as reported in the
- "SZ" field of "ps -l"
- - don't give a file its complete pathname in argv[0]; only
- its filename (religious issue?)
- - history recall should start at the previous command, not
- the current one (typing "r r" causes an infinite loop)
