buggy paste highlight with backward-extend-paste

buggy paste highlight with backward-extend-paste

[Vincent Lefevre]

When using:

  autoload -Uz bracketed-paste-magic
  zle -N bracketed-paste bracketed-paste-magic
  zstyle :bracketed-paste-magic paste-init backward-extend-paste

if I type:

% echo foo

with the cursor just after "foo", and paste "a", then the whole
"fooa" gets highlighted instead of just "a".

That's intentional, not a bug.  The paste was extended backward.

But I don't want to extend the paste backward!

Note that I have the zstyle above just to make the paste correct in
the following case:

# Helper/example paste-init for exposing a word prefix inside PASTED.
# Useful with url-quote-magic if you have http://... on the line and
# are pasting additional text on the end of the URL.
#
# Usage:
#       zstyle :bracketed-paste-magic paste-init backward-extend-paste

But affected the highlight is not expected.

So I gather, but I did name it that way for a reason. :-)

This is one reason that Mikael keeps pushing his simplified variant where
you have no choice but to paste the entire URL rather than just a suffix
of it.

To "fix up" the highlighting, you'd also need a paste-finish action to
coordinate with backward-extend-paste.  E.g.:

- In backward-extend-paste, save $bep_words[-1] in a global variable.

- In the paste-finish function, compare that saved global to the
leftmost part of $PASTED, and if they match, delete it from $PASTED
and append it to $LBUFFER.

- Also in paste-finish, possibly fix up the position of MARK.

If you come up with something that works, I'd be happy to look at it.
Otherwise it may be a while before I make an attempt.

backward-extend-paste is needed even when pasting full URL's.
For instance:

$ wget '

then paste: http://localhost/foo&bar
