Re: Incremental search don't append wrongly typed characters

[Dmitry Gusev]

Drew, thanks for the answer. Unfortunately I need a different behavior in my particular case. I was proposed with similar work-around also on stack overflow. Though, I'm often using incremental search for query specific tags in a large text file which is used like database system with help of some configuration and scripts. Before each incremental search there is a macro which places me to BOF and afterwards starts incremental search. For this scheme it would be very convenient just not to append mismatched part at all. I understand that it's not that standard feature and I use different approach when let's say coding or typing text but again for this particular case I need the mentioned behavior. It will save me some additional clicks to backspace and/or c-s  c-g. In other words: I'm  looking for a way of not showing mismatched characters during incremental search. Thanks a lot for your time.

I don't have an answer for you, but the suggestion is an interesting one.

A variant that could be useful (which I also don't have a recipe for):

Type `keyz'.
The `z' is highlighted as a mismatch (this is already available).
Hit a key to delete the mismatched part (in this case, just `z'.
Type `s' and continue.

When I introduced highlighting of the mismatch part, I took it from Icicles
highlighting of completion input mismatch.  There, you can hit `C-l' twice to
remove the mismatched part.  (The first `C-l' just moves the cursor to the
mismatch beginning, so you can insert there.)

In Isearch there is no equivalent - no key that removes the mismatched part.
Maybe I'll add that possibility.  What you can do is hit `M-e', which puts you
in editing mode and moves the cursor to the mismatch beginning.  Then hit `C-k'
to kill the mismatch portion, then `C-s' to resume searching.  So `M-e C-k C-s'.
