I'm unable to reproduce that here.  Do you mean that in an arbitrary
buffer simply enabling `url-handler-mode' and `ido-mode' impedes you
typing that URL?  Couly you please give a precise step by step
description with emacs -Q?

Forward from where?

Hi Kim,

Here's a bug report about ido-mode.  Do you have time to take a look at
it?  If not, suggestions about how to fix the problem would be welcome.

Hi Chong

Ido already has code to deal sensibly with tramp syntax.  It does this
by calling tramp to return completions for a given input matching a
tramp-like filename.

Maybe there is a similar way to do that for the url package, by
checking the input against url-handler-regexp, and calling the
url package's completion functions.

Unfortunately, those are unimplemented, so there really isn't much
ido can do to "improve" url-handler-mode:

(defun url-file-name-completion (url directory)
  (error "Unimplemented"))

(defun url-file-name-all-completions (file directory)
  (error "Unimplemented"))



This is a major reason why ido provides the C-f fallback to standard
"find-file"; then you can enter stuff which doesn't have a reasonable
ido semantics.

So really there is no bug here - it's one of the IMO very minor
problems of using ido.

I intend to close this bug if no one objects.

No, it should be fixed instead.  The fix is pretty simple: make
url-file-name-completion and url-file-name-all-completions return
a valid value which represents the fact that we don't know what could be
the completions ("everything could be a valid completion") instead of
signaling an error.

Do you mean removing all of the following in url-handlers.el?

,----
| (defun url-file-name-completion (url directory &optional predicate)
|   (error "Unimplemented"))
| (put 'file-name-completion 'url-file-handlers 'url-file-name-completion)
|

|   (error "Unimplemented"))
| (put 'file-name-all-completions
|      'url-file-handlers 'url-file-name-all-completions)
`----

Also, url-handler-regexp and tramp's syntax seems colliding.

You could start with that and see how it behaves (maybe it won't work
right either since it would presumably call those functions with the URL
as if it were a local file, better might be to keep the code but make
the functions return a "correct" value).

Never had a problem with that.

url-handler-mode is awesome!  ido-mode is too, but they are not
compatible with each other.

With url-handler-mode and ido-mode enabled, try typing
http://www.google.com.  ido-mode will not let you type in that url.
You need to use C-f to enter "normal" url handler mode.

If the long-term plan now is to phase out the entire url library,
perhaps we should close this as wontfix?

url-handler-mode is something I haven't examined closely, but I think
it's something that's kinda separate from the main url.el, and should be
reimplemented on top of the new URL interface in Emacs 28-ish.  As such,
this bug sounds like it would still be a bug then, so it's something
that should be fixed.
