: you do have "ordinary" scrolling - just use the middle button,
: as it says in the manual.


sorry, but this doesn't work for me! middle button doesn't scroll at all-- just sweeps and executes.
I tried to find it man 1 acme, but there is nothing like
please, tell me *how* do you scroll the tagline w button2 ???



>as someone else said, if you want more text than will fit in a tag,

try |wc in [new] frame (not in tag) and it will apply to itself, not to the dot in the last active frame! And what about |sed 's/blahblahblah.....long/BLAHBLAH/g' ? 
(As I mentioned some time ago, I dont like hardwiring the 'Edit' cmd into Acme: what about [better sed | stream sam] instead? maybe I am wrong all the time, but isnt it (Edit) against plan9 ideas?)

You could try using the old edit interface
as described in the acme paper.  It was clunky.
Piping things through sed or just running sam 
to do what you wanted was much better.

In contrast, I use Edit almost every day, to do
things that you can't do with sed.

Thank you, rob.  Anyway, 2-1 chord solved
the narrowness of taglines for most part of mine
(html and c source editting).

By the way, I changed the return key to execute the
selected commond in a tagline, i.e type a command
in a tagline, press ESC to highlight it then RET to
execute it.  I will see how I like this or not.

As someone else said, Edit commands typed in the New'ly
created scratch window can't be applied to contents in
other windows, if I'm correct.  And when everytime I want
to execute one of them, snarf&paste it into the intended
tagline and execute it is painful.

Rather, I have something like this at the top of a Zerox'ed
window and use them.

Agreed. But autoscrolling horizontaly without any scrollbar
when typing past the right end of a tagline could be helpful.

It would be great to have a `blessed' (non-hack) solution to make the
filenames less obtrusive. With unix acme the filename is regularly
longer than the width of the tag, meaning one would have to scroll
in the tag even to Put or Un/Redo - this takes away much of the joy
of using acme.
The env var hack makes acme usable for me on unix, and I'm happy to
use it until a better way of dealing with long filenames comes along.

> does acme use existing environment variables, like wily does?

No, but, for the unix acme you can find a patch in the
plan9 ports CVS repository (no idea how hard it would be to
back port it to plan 9).
I slightly patched that for even more comfort, see below.


Axel.


One thing I noticed: the sorting in mkruneenv pays
special attention to the env var names: case and length.
For me, even more important is that I get the env var
for the longest file name, so, if I have

	home=/home/me
	fo=/home/me/fo
	fofoo=/home/me/fo/foo

then when I'm in directory /home/me/fo/foo/bar
I would like to see $fofoo/bar and not
$fo/foo/bar, and certainly not $home/fo/foo/bar .

I cooked up the following patch, just tested to
see if it works, not used long enough to notice
I overlooked something, nor to know whether it
works as comfortable as in wily.

does acme use existing environment variables, like wily does?

from the idioms webpage (http://www.cs.yorku.ca/~oz/wily/idioms.html):

Short-cut Environment Variables
Set environment variables to make window labels shorter and easier to 
type, e.g.

	h = $HOME
	wilysrc = $h/src/wily/wily
	wilybin = $h/obj/$cputype/wily/wily

Re: [9fans] acme design

[a]

// the list will always take you to the correct 
// place [current window?], won't it? 

i just don't see how. i mean at a functional level - like, what's the thing
*do*? highlight the file my cursor's over? what's the behavior?

// cursor position | highlighting in "listing/tag window" not sufficient?

nope. i want to know by looking at the window i'm typing in, or as close
to it as possible. not some (mentally) unrelated window in another Col.
it's not so much an issue while i'm typing, but when i'm switching from
one win to another, how do i know where to move my mouse?

// use last "ordinary window" [for execution] ... i think 

i don't think that'll work. if i'm editing a window at the top of a Col and
the "tag" window is at the botom of the Col, or two Cols over, how do i
get to it without mousing over another normal window? or do i have to
make some manual change before i can edit that window?

// isn't a tag "line" a special frame that [currently] behaves 
// differently from "normal" one?? 

yes, which is exactly why i said it was a reasonable thing to question. i'd
be interested in ways to structure things that don't have this modality in
them. but i certainly can't come up with one.

// my "tag frame" i think could behave just normal 

except for auto-highlighting or some other indication method, and
automatically updating itself for the list of open files (hopefully!). and how
would i refer to it? how would i Put it?

// as much as you wish, of course, as normal ones... 

this is space-ineffecient. i'd always be resizing it. the current window
tags are (intentionally or no) optimized for the small data they contain
(perhaps too much, hence the splinter-thread about scrolling).

this would only rarely be useful to me.  (although it would be nice to
have some visual indiciation of the "current" window - i was quite
perplexed recently when clicking on Zerox in a window's tag Zeroxed
some *other* window...  at least Edit doesn't work like this)

it's the fact that i can't have narrow columns when i'm working with
deep filenames that gets to me.

I wonder if it would help any to keep the name of the most recently
active window in the top tag bar and allow commands in that tag bar to
apply to the window it indexes.  Keeping focus is then harder, of
course, but that has always been controversial anyway.

as someone else said, if you want more text than will fit in a tag,

there's not enough space in a tag for scrollbars.

you do have "ordinary" scrolling - just use the middle button,

Re: [9fans] acme design

[rog]

i been thinking that one way to make the filenames less obtrusive in
acme would be to allow grouping of windows with a common path prefix.

i quite often find myself working in, say
/n/dump/2004/0529/usr/inferno/appl/cmd/scheduler/...  and that really
doesn't give much space for tag commands.

i could imagine some kind of directory-tagged super-window in acme
that contained other windows.  windows inside it whose names were
prefixed by their super-window's tag would show only a pathname
relative to that directory.  dragging a window outside would show the
whole pathname again.

looking at the acme window i'm writing this email in, this would save
much space, and provide a reasonable way of organising windows too (i
quite often find myself doing a Sort, or typing a full pathname and
right-clicking on it, just to find a particular window).

at least with something like this it would be possible to look at an
acme window and work out where all the files are, something that's not
possible with the env var hack, for instance.

no. have as many cols as you wish [see Newcol] . New frame, like new column,
could appear just at the end, and zou could drag it anywhere.

The direction which we took for our marsv. ☺

By the way, I don't want to make debate here, however, I could
recommend you to forget the acme's way if you want to make
something new user interface for Plan 9.   Acme's way is good
for text things, I know.  If you are thinking of an extension of
acme for text thing, I think it's not so interesting to me.   Acme is
good enough to me.

Apologies if this sounds flippant, but your comment above makes me
want to ask: What do you keep in your tags?  Whole scripts or
paragraphs of text?  I use middle click on New and type in the new
pane for stuff like that.

The only times I have difficulties with text length in tags is when
using acme under Unix, as I have less control over most of the
absolute filenames.  And files under Unix tend to live in very deep
directory hierarchies.  Which incidentally, led to the introduction of
the special way environment variables are used by wily.

isn't a tag "line" a special frame that [currently] behaves differently from "normal" one??
my "tag frame" i think could behave just normal, bringing up the frame named bz text as it
does in usual frame, so does the "command frame" with ,maybe, one exception that it must not 
apply commands to itself, but to the last touched frame, which it must know ... however, it doesn't need to differ from
current behavior of a tagline, does it?

Re: [9fans] acme design

[a]

maybe, but i still don't get it. :-)

or maybe i do and i'm in denial. i see two "content" frames, a tag
frame, and a command frame. what determines which content frame
the commands operate on? how do i know which "content" frame is
which in the tag list?

this model seems to eliminate the tag bar as distinct from the

"normal" frames (which seems good - they break the "all text is
equal" theme that's present elsewhere) but then introduces several
(at least two, possibly more i can't see) new types of "special"
frames. this adds more modes to the operation of the interface,
which is bad. it also significantly increases the amount of mouse
motion needed to execute Tag items (even assuming some magic AI
for tracking which frame you're talking about).

what is it you think this model gains you?

(i'd like to see either multi-line or scrolling Tags, to avoid loosing
bits when the Tag gets too long, and the ability to create Rows at
the top-level like i can with Cols. these are certainly more
incremental (an thus possibly less exciting) than your suggestion,
but i'm pretty sure i can clearly show the benefits.)
