Does it strike anybody as annoying that control-E takes you to
the end of a commented line (ie to the end of the comment) rather
than just the end of the final s-expr on the line? I know I sure
Personally, I couldn't do without this functionality. My Lispm-Init
loads the following nifty function, by JWalker:
"Goes to the end of the last /"real/" character on the line.
This provides a way to get positioned on a line so you can add to or modify
the code, not the comment. A numeric argument specifies how many lines to move.
I don't see how people live without this. Maybe if you never comment your code
you don't notice that this is missing. " ()
(let* ((the-line (bp-line (forward-line (point) ;find the line wanted
(if *numeric-arg-p* *numeric-arg* 0))))
(index (find-comment-start the-line t))) ;index for comment
(cond ((null index) ;no comment on line
(move-to-bp (end-line (create-bp the-line 0)))) ;so just go to end
(move-to-bp (backward-over *blanks* (create-bp the-line index))))))
My init file does a login binding of this function to s-E, which isn't
quite kosher, but has mnemonic value.
How about a control-E that takes you to the end of the final bit
of CODE on the line, then, if another control-E is done, you can
access the end of the comment text?
c-E is very strongly entrenched in all modes as meaning end-of-line. I
am against changing the meaning of c-E for this purpose. Better to let
c-E still always mean end-of-LINE, and some other key binding like s-E
