Two questions I've come up with while doing this: 1. Is there a way to get the unescaped commandline?
'commandline' returns the escaped commandline, which is great if you want to evaluate it, but not so good if you need to edit it or manipulate the cursor based on the content in it. commandline -C returns the cursor position of the unescaped version, which is therefore inconsistent with commandline. In my bindings this subtle difference can cause some minor issues with the B, E and W commands (i.e. move FULL word, which no builtin command provided). You can see how my script uses the difference between commandline -C and the length of the string returned by commandline -c to work out how many characters have been escaped. Obviously that isn't a perfect solution, but it is close enough for now. Directional commands may be more of a challenge as they will need the ability to manipulate substrings of the commandline, and processing an escaped version of the commandline won't really work very well at all. 2. Is there a way to get the key that was pressed to trigger a binding? It seems that the only function that can do this is the builtin self-insert. I wanted this to implement a mode that changes the behaviour of all keys (replace mode causes the next key pressed to replace a character and return to normal mode for instance). At the moment I implement this by binding all the keys in the range 0x20..0x7e when entering replace mode, which is kind of nasty and not very locale friendly.
