[9fans] acme search backwards

[Rudolf Sykora]

Hi,

by chance, hasn't somebody changed acme so that one can easily,
say with a ctrl key, change the direction of the search done by the
3rd mouse button? I find it very missing.

Thanks
Ruda

I had done https://bitbucket.org/mpl/acme-with-easy-backwards-search , but
since I wasn't bright enough to host it as a diff I don't really remember
how it works or what I changed. I think I had added a Rev command to the
tag bar of the window. Although it wasn't useful enough for me to keep on
maintaining it, I'm pretty sure it was working.

Also there was a discussion on 9fans about it with other
suggestions/solutions.

is what I remember Russ recommending,  It's not perfect, but it does help.

Page 4 of A Tutorial for Sam Command Language, by Rob Pike, suggests
the following usage:
>>>
Just precede the pattern with a minus
sign, which reverses the direction of the search:
-/Emacs/

Similarly,
$-/Emacs/
finds the last occurrence in the file, so
0/Emacs/,$-/Emacs/
selects the text from the first to last Emacs, inclusive.

I actually know all of what you write, and the question
was meant explicitly differently.
I.e., the suggestions you mention are still far from reciprocal
to a b3-click on any word in the text file.
Copying (or even selecting a whole portion of) a word to get
it into a formula like :-/.../ somewhere is ugly, to say the least.

Thanks anyway!

It's just one of those Pandora's boxes, once it's open it can't be
closed.  I have continual trouble with unintentionlly pressing the
Cape-Lock key at the same time as the letter A and finding myself
typing text at the beginning of the line (which could be a paragraph,
in Acme) instead of the place I was at one Ctrl-A earlier.

Still, you could set an indicator that reverses the direction of B3's
search.  It's just not all that useful and programming it and testing
it may be more effort than you gain from the trouble.  Also, knowing
which way you're going next time you click B3 may not be very clear
and you further need to decide whether it is a window-wide or global
setting.

No, I meant other implementation suggestions.

Since you're all as lazy as I am, here it is:

Thanks for the link!
I wonder, why is it that they claim that implementing the functionality
of:
3b = search forward, shift+3b = search backward
is not feasible on plan9...

because the keyboard doesn't pass modal presses to user space, and devmouse
already takes shift+right -> middle, for insufficient mice.

There has been solved in 9front in 2011: http://man.cat-v.org/9front/8/kbdfs

somehow I thought that was going to be the response, but that's not really true unless acme has been rewritten on the lower level kbd model.

that model also introduces user space kbd control, so good luck using it in the event of panic.

Sorry, I don't orient.
Does it all mean that I could nowadays possibly get the wanted behaviour
(using, say, ctrl+3b for the purpose) on 9front while I cannot on
the original plan9?

Thanks
