Re: [9fans] acme Put doesn't save

While learning some of acme's basic commands I was also shocked by
this, and I agree with Ruda that executing a Put with a non-existent
file (e.g.  '/home/ruda/a' ;-) should save the contents of the window
in that file.
Probably there are other ways to do it, like Edit w /home/ruda/a, but
the ones I've seen so far involve a little more typing. Is it just out
of the question to implement Ruda's suggestion? (if it was a
suggestion at all)
It is just a little more comfortable, and it fits very natural into
acme, if you ask me.

this isn't true.  if you click on New and then type something
for a filename you will notice that the tag line box becomes
filled and then click on Put, the file *will* be saved, even if the
file does not exist.

if on the other hand you try to modify the name of a directory
listing frame, the tag line box is not filled.  this is a hint
that you're doing something wrong.  also there is no Put option.
this is a bigger hint that you're doing something wrong.

the reason that directories behave differently is that in acme
programs are allowed to take over a window.  while the directory
listing is built in, it operates on the same principle, and it does
not make sense to write a directory through acme's interface.

It is, if you considered the fact that I was talking about adding a
file name into an already existing window tag showing the contents of
the directory, and not about using Put in conjuction with New to
create an empty file (which is the case if you execute New with a
non-existing file and then you inmediatly execute Put, but why would
one do this is unknow to me)

not really - +Errors windows fulfil both of those criteria,
but Put works fine in those.

i agree it doesn't make sense to write a directory, but
you can't anyway, even if the interface allowed it,
and the resulting error message would be self-expanatory.

personally, i think that Put should work on any non-application
window, and that re-columnation should only take place if
the textual content hasn't been modified by the user. (and
probably also that if you change the name of a window to a directory
name and do "Get", that it would get a directory listing).

but YMMV as always.

You may call it a hint. I noticed the 'Put' doesn't appear there. But
(non-)existence of sth in the tag line doesn't mean it can't be
issued.

Moreover, I still can't see why it can't work. If I change the tag
line by appending a name (which is not, say, a name of a directory
within the current directory), I don't understand why this couldn't be
saved... and the window couldn't represent the new (or changed) file
from now on.

Re: [9fans] acme Put doesn't save

[Rudolf Sykora]

It really seems that acme-sac does save in the described way (at least
it saves). That makes me wonder. Do plan9 acme, p9p acme and acme-sac
have more similar differences? Are the programs separate in their
development?

Acme-sac is based on the Inferno Acme, which is written in limbo and
has a few minor discrepancies to the P9 acme (for example, backspace
with text selected only deletes the selected text, it doesn't delete
the character prior to it).

Acme-sac is a life saver on windows. I couldn't live without it. Big

I think the attached patch is what you are proposing. If you apply it,
when you edit dir windows, the file menu will be added (Undo, Put will
only appear when the window name changes), and columnate won't be
called for that window. If you execute Put in that window it will be
saved, if the window name is a directory there will be an error.
Another changes I did is that now if you edit the title of +Error
windows the file menu will appear, and Get will appear when the window
name finishes with '/'. I haven't tested it too much, but it is
working here.

what command is to be performed?

The easier solution that comes to my mind now is Edit w filename.
I haven't looked into it, but I think you lost the content of your
window because when directory windows are resized acme columnates them
again (which is a nice thing, if you ask me).
It would be good that the isdir flag of a window changed when you edit
its name. I will have a look (playing with acme source is like my new
hobby...). It is not too consistent now: you can remove the basename
and then do 'Get', but you cannot add it again and do 'Put' (I'm
talking by memory. BTW, everything works as expected in acme-sac, the
only acme I can use at work).

Well, I had some text in in-this-way created window and I only grabbed
the window trying to place it in another column and suddenly it was
all empty... :( All my text not only not saved, but lost completely...
This isn't nice.

So is there a workaround other than 1) make a new window, 2) copy &
past the text there 3) save from the new window?

I thought that the decision when it saves and when not should be
directed by the name format: ending with / then not save, ending with
sth sane, save...

Because at the beginning of the put function in exec.c you have:
	if(et==nil || et->w==nil || et->w->isdir)
		return;
and et->w->isdir is true. But there are workarounds if you want to
save the contents of the window.
