Ah thanks, I always forget private is the default in bitbucket.

yep.

you commited only the final version; it'd be easier to read if you commited
first vanilla and then your changes.

please explain: how's your Rev command better than searching via :-/REGEX? Is
Rev the equivalent of Look?

[Mathieu Lonjaret]

As the description says:
"I found I want to quickly look for something upwards often enough
that it was getting annoying to have to type :-/ or :? everytime. With
this I just have to exec Rev in the tag bar to reverse the search
direction."
Furthermore, with :-/foobar, you have to go back with your mouse to
the tag bar where you typed this for every subsequent search.

missed that one, thanks. looks good.

that depends. if you first select the whole :-/REGEX with left mouse button
and then right-click, the cursor remains over the expression and you don't
have to return to the tag bar.

Ah, yes. scratch my last remark then.

[Peter A. Cejchan]

would it run on native plan9, too?

I haven't tried, but I don't see why not.

[roger peppe]

i'm not sure about adding more invisible state to acme
windows.

i've sometimes imagined a version of acme where shift-right-click
would reverse the search. no way of implementing it under
plan 9 itself though.

if `hidden' is the keyword, then let's have some new files in acme's control
file hierarchy for various bits of state.

aside of Rev, also paths from the Include command, the `dirty bit' that affects
behavior of Del, Delcol, and Exit, and any other elements of hidden state. a
few new files per window.

privately i think the Rev command is redundant, but meh.

For example, if the first thing in the file is:
<?kzy irefvba="1.0" rapbqvat="ebg13"?>
an XML parser will recognize that the document is stored in the traditional
ROT13 encoding.

Well I needed to do that in a hurry, but I'll gladly reimplement it
later better if you have a nice suggestion.

Yeah my first idea was with ctrl+right click but I figured it was
easier/faster to just add it as a text command.

Another option is to use a right-click on Look to search backwards.
Then, you will need a workaround to look for Look, but I guess you can
live with that. The exception is not pretty, but it could be
convenient.

making the state available to programs doesn't really cut it for me.
for it to be useful in moment-to-moment interactions with acme,
it must be visible on screen, in the same way that the dirty
bit has the top left indicator (well, mostly).

> privately i think the Rev command is redundant, but meh.

well, i've gone all these years without it, so it is redundant in that
sense, but it still feels a bit awkward when browsing a large file
and right clicking one-too-many times, that i have to copy the
text to the tag, insert :-/, reselect and/or quote metacharacters,
and click. it's a sequence i often get slightly wrong too
by getting the selection slightly out.

a single-click reverse search would quickly internalise and be
very useful i think. the difficulty is coming up with the right way of
doing it.

Maybe a chorded 3-1 click (not 1-3).

+1
3-2 and 3-1 both do the same thing currently AFAIK,
so one could go.

[Rob Pike]

i don't think either does anything.

indeed, but it's a useful nothing - they cancel an impending b3 action,
useful if you're sweeping with b3 and started in the wrong place.

rio doesn't have button 3 search. acme does.

Old (pre-p9p) 9terms had it, in the menu as "fwd" and "bkwd".
