bug#40269: Emacs should recognize "file:" when opening files

[積丹尼 Dan Jacobson]

Emacs should recognize file:///home/bla/bla/h.html
That way users could do
$ set file:///home/bla/bla/h.html
$ $BROWSER $@
$ emacs $@
etc. and they would all work the same!
No I don't want to use extensions.

What should it do with this input?  Start eww?  Edit h.html?

Well emacs is an editor so I suppose it should edit it.
But OK it could also browse if it insists.
Anything is better than the current behavior of totally not being
prepared for file:/// .

I don't know whether that makes sense at all.  I just don't see the use
case of feeding an URL to Emacs and then expecting to be able to start
editing it.  It's a pretty obscure thing to want to happen.

So I'm closing this bug report.

Is there an actual use case here, or are we inventing it as we go?

Sure:
$ emacs file:///etc/motd

Use M-x make-directory RET RET to create the directory and its parents

What a "outdated" response from emacs.

It should at least say "I am emacs. I know you used a file: URL. I know
file URL have more meaning than arbitrary zzzz: URLs. But I currently
don't have a consensus about what to do with them right now." At least.

That's not a use case.  A use case would be when you describe that you
have this-and-that problem or need, and the natural solution is to use
the file:// URL to access a local file (instead of just naming the
file as usual).

bug#40269: Emacs should recognize "file:" when opening files

[積丹尼 Dan Jacobson]

Let's say I browse a local file in a browser.
Now I want to edit it in emacs.
Well if you let me just copy the whole URL, including the file:///
things would be great.
But just because emacs was born in the 1970s or something,
I have to remove the file:/// else emacs totally can't deal with it.
Everything else can deal with it, except emacs.
For emacs I have to do DEL DEL DEL DEL DEL DEL DEL each time.
That's because emacs hasn't been updated since 1970, the user feels.

That already works: "M-x eww RET" in Emacs, copy the file:// URL to
respond to the prompt, and voilà!  If you actually need to modify the
file, type "C-x C-q" and proceed editing to your heart's content.

Actually, the latest change to Emacs were today.

I want
$ emacs file:///... to do something, anything (non-dumb).

How about having to do M-x find-file instead of being able to enter
things from the command line? Yuck.

And what "major savings" is "breaking" file:/// buying emacs anyway?

I already have enough
$ typeset
emacs_w3m ()
{
    emacsclient -e "(w3m \"$@\")" && wmctrl -a macs
}

And yes I can hit E there to edit the file. That's not the point.

I saying that if chrome, firefox, can deal with emacs' /nurds/burg
then it is only fair that emacs should be able to deal with
chrome, firefox's file:///nurds/burg .

Also I bet emacs isn't "RFC compliant".
I'm sure there is a RFC that says
"Programs MUST translate file:///nurds/burg to a local resource" or something.

Emacs _can_ deal with file://, you just need to invoke "M-x eww"
instead of "M-x find-file".

Why are you insisting on using the latter?
