[9fans] hack for acme

[9fans] hack for acme

[paurea]

Following the suggestions made in the list, we made some changes for
acme in order to be able to navigate directories reusing windows.
First we used the exec button, but didn't work well (for example
inferno in /usr can be a directory or a program).  After that we tried
the chord 3-1 which seems to work well.  diff is attached.


          A mouse chord of buttons 3 and 1 (clicking 1 while holding
          down button 3) opens a new file/directory in the current window.
          This chord works only when the window tag corresponds to a
          directory. It is useful to navigate through deep file hier-
          archies without opening each directory in a different win-
          dow.

[9fans] Hack for acme

[paurea]

Nemo included the changed files on sources.  You can pull them from
nemos directory.

Re: [9fans] Hack for acme

[Russ Cox]

We did not include the 3-1 change in our acme, mainly because 3-1
cancels a 3 that you've started and want to back out.  In other
words, as Rob pointed out before, 3-1 is already taken.

It might be reasonable to use 2 to ``exec'' a directory by opening it
in the same window, but then there is the inconsistency that 2 on a
directory and 2 on a file behave differently.  

I think that if I had the ability to open a directory in the same window,
I might use it a fair amount.  I'm not sure how much I would use the
open a file in the same window capability.  I'm still thinking about 2.
But 3-1 won't happen.

Paurea and Nemo, how much do you use your 3-1 on files vs. directories?

Not to be argumentative, but so does 3-2.  Not including a seemingly
useful feature because you don't want to change the behaviour of your
fingers under a seldom used mechanism seems foolish.  If you want
1 to cancel a 3 click then it should be across the board and cancel
a 2 click as well.  Regularity shouldn't be an option.

Since 1 is useful for X with args, it can be useful for open with args.
Suppose the concept whereby the user highlights a string
representative of the window he/she wants the open to occur in.
If you highlight, say, `.' you mean ``open here.''  Otherwise,
you could open all docs in one particular window.  Perhaps there
are other uses.

I'm not certain of acme's internal window naming organisation,
but this seems doable.

I'd like to see this to be an option that modifies the nav behavior
for directories (like -b is for selecting windows).  3 is more
natural.  If window is a directory, and you click-3 on a directory
inside of it, reuse the window.  If the window is some random buffer
and I type in the directory name and click-3 on it, that should open a
new window. my 2¢

What we do is to make our changes and after experience says if
we are using them or not, we keep them or delete them. I just deleted
the Ignore command I added time ago to acme because we found that we
have seldom used it.

Regarding 3-1, paurea is using it a lot on directories, I've used it
several times these days, but I still don't know if that's really useful
for me or not. If after some time we find that we seldom use it, we'll
delete that feature; but I think that we'll be using it a lot (at least
paurea is doing so, and I think I'm going the same way).

On files, I *never* used 3-1. Well, I used it once when I first tried
acme, just to play with undoing buttons. I don't know for sure, but I
think paurea never used it either.

Most times, I notice that I used 3 to open a wrong file (eg /dev/zero and
alike) after I released the button (which makes 3-1 no longer useful as
a cancel).

On the other hand, we had 2 on directories instead of 3-1 some time ago.
It was confusing because some directories correspond to program names in
/bin. That's why we decided to move to 3-1 instead of keep on using 2.

Or, you used it a lot, by default..

You can do that with 3-2. One of the two chords is expendable... Anyway
this is limited for dir tag windows.

Yes, we already tried that and it was difficult to know what the user
wants.  For example with src on /usr or changing to the directory of
inferno.  My first choice was to execute and go into directories and it
had a very bad result. I then tried execute everywhere, go into directories
just on windows with dir tag and it was frustrating. If something is
a file you can execute (without path) and a local directory without path
I haven't found an easy way to decide what you want to do. I didn't try
the selected dot strategy though, which may be an alternative, because
I found it a little bit awkward.

I use it almost mainly on directories and almost always I open a dir buffer I
use it at least once. That is quite often.

I missed it on both for a long time. Thanks 4 "hacme", folks!
PS: I would vote for a history filke for acme windows, too ;-)

oooops, no, no, NO! (I just didn't think for a moment).  there's a tag, of course...

I pulled 3-1 acme from sources/nemo and yes, it is convenient! I only miss the same functionality on files....

It should be easy to add, but I don't find it as useful.
