Re: [9fans] how to undo in Rio shell window and Acme editor?

[Ethan A. Gardener]

As a small extra hint if you ever need to work outside Acme, any delete of 
selected text is effectively a cut. You can paste it back in. I used to use 
that like undo all the time.

Thank you very much, these combinations do work well!

A little supplement,  Command-z works in acme but not 9term, anyway, that's 
fine, I can embed term in acme.

Alt+Click does a middle click (button 2), Command+Click does a right click
(button 3). Also, Command+Z does what's expected.

Re: [9fans] how to undo in Rio shell window and Acme editor?

[刘宇宝]

Yes, "win rc" embeds a rc shell window in Acme, I can undo in the shell window, 
 that's perfect!

But the edit in tag line can't be undo,  I find the Undo command has no effect 
if it's on the top main tag line or the column tag line,  it only works on 
window tag line and only undo editing in the text window.

I tried p9p Acme on Mac OS X, seems the mouse button emulation with trackpad is 
broken, p9p Acme doesn't response to Shift + Secondary Click,  this is probably 
my problem, won't play it now until I'm more familiar with 9front in Virtualbox.

Thanks a lot!

Re: [9fans] how to undo in Rio shell window and Acme editor?

[刘宇宝]

Excellent! This indeed gives an rc shell window embed into Acme editor, and I 
can undo editing in it,  right what I want!

Thank you very much!

Re: [9fans] how to undo in Rio shell window and Acme editor?

[Raingloom]

Even if you are not in a `win` window (eg. if you are in an +Error one) you can 
use Undo. Sometimes Acme doesn't actually put Undo in the tag line, but if you 
type it out yourself it will still work. Well, at least on p9p Acme, I'm not 
sure about Plan 9 Acme.

Re: [9fans] how to undo in Rio shell window and Acme editor?

[Chris McGee]

There’s a ‘win’ command you can executed in acme to get an interactive rc shell 
window.

 Both the Ctrl key and the z key are fully supported on 9front Systems.
 To remove undesired characters from the screen, the Backspace key is
 also automatically provisioned, free of charge.

Re: [9fans] how to undo in Rio shell window and Acme editor?

[刘宇宝]

Great thanks for your idea,  file oriented design is very flexible! The prompt 
function may be used to automatically backup the output of previous command,  a 
poor man's undo buffer :-D

I tried to execute "rc" in Acme, seems Acme always execution command with 
/dev/null as stdin, I can't embed an interactive rc session into Acme and 
leverage the undo buffer of Acme window.

Re: [9fans] how to undo in Rio shell window and Acme editor?

[刘宇宝]

I often messed the output of previous command by accident, either by typing or 
mouse chords to cut or paste, then I can't copy original text :-(

ACME focuses the window under mouse cusor by default, I also often wrongly edit 
the tag line...

Indeed need some time to get used to it.

Re: [9fans] how to undo in Rio shell window and Acme editor?

[Steve Simon]

hi.

i think it is humour of a kind.

i cannot speak for acme but rio has no undo buffer, so what you ask for is not 
possible.

you can save a windows content (including history). e.g. /dev/wsys/11/text /tmp 
(assuming the window you want is number 11, cat /dev/winid to get the current 
windows id)

[9fans] how to undo in Rio shell window and Acme editor?

[刘宇宝]

Hi all,

Recently I started an adventure to 9front and found Plan 9 very 
interesting.  I have thoroughly read the FQA and manual pages at 
9front.org, and searched the web, but still don't know how to undo wrong 
typing in Rio shell window and Acme editor's tag line,  I'm surprised 
and not so used to the facts that:


* I can edit the output of a command in shell window, no way to undo

* I can change or delete the tags for Acme editor and its column, no way 
to undo,   although the tags for Acme window can't be edited.


I miss much the *universal* shortcut Ctrl-z on Window and Command-z on 
macOS,  does Rio and Acme have the equivalent?



And one more question about Acme: how to quickly enter command? In VIM, 
I can enter ...comand, in Acme I have to move cursor to 
command area and click, input command, press ,  click middle mouse 
button on the highlighted command, is this the fastest way to input 
command in Acme?



Thanks,

Yubao Liu
