I find it useful to have an "Exit" menu entry, sometimes.
An opt-in option seems reasonable.

The one I miss was the Look option from 9term,

that was very handy on occasion, to find a previous
command that was lost in voluminous output.

Marvelous!

don't shoot me I am still in the land of the labs
code with some bits of 9front, rio will now be one of those.

That's why I included the commit info, so you could grab the code if you
wanted.  I'm a big fan of Look in rio!

Look was added to 9front rio years ago.

I implemented rio exit with confirmation in exactly the same way as mothra; same "ok?" icon and everything.  Does this sound good?  If so, I'll update my patch, health permitting.

Re: [9front] rio exit menu

no, that's horrible. if i want to exit i want to exit.
(now i can see this will never get anywhere. give up hope everybody)

Well, everyone always did maintain their own rio. :)  I have no objections whatever anyone wants to do, any more.  I have just discovered my old code is buried on the old FS I couldn't be bothered with any more.  (Quite liberating, forgetting about all the things you once wanted to save.)  I could dig it out or I could re-create it, but frankly, if I could create it in the first place, so could just-about anybody else. :)

cursor source:
/sys/src/cmd/mothra/mothra.c:/confirmcursor

that goes in rio/data.c; then I think you want to pull a very short function from mothra too, and assign it as callback for the exit menu entry.  It then should probably call rio's own exit menu callback which can be invoked if rio is started as 8.out or whatever.  Something like that!  Huh... I could have done the work in the time it took to type that! lol not really.

Re: [9front] rio exit menu

I decided to post my patch to 9front contrib, when it's redone.  I'm thinking it might be best if all these patches were put on contrib.

Re: [9front] rio exit menu

[Ethan Gardener]

More complete patch, only because it turned up as a preliminary to what I intended to do.  I can't post it on my contrib now although I do think that's the best place for such patches.  I'm too stressed to look up how.

I used it to close the window, being tidier and sometimes more accessible than selecting Delete in the parent.  Come to think of it, I didn't close subrios very often.  It only got used when I was shutting down to get the window out of the way so I didn't think its contents (extra editors) still needed to be closed properly.

I'm starting to think that old patch of mine shouldn't have worked when it did, calling emouse from a program which doesn't normally include event.h.  Yay for blundering into functionality.  I remember doing that & then fixing it at a later date, but can't remember how (or how well) I fixed it.

Re: [9front] rio exit menu

[qwx]

Fair enough.  Calling off the paratroops.

Fwiw, I use subrios a lot, and it comes handy.

Thanks!

when you want to reuse the window.

Re: [9front] rio exit menu

I agree with Julius.

Serious question: When and why do you need to kill rio cleanly?

I'm opposed to this change.
I would kill too many rios by accident :)
