bug#16258: 24.3.50;[PATCH] eww: Add new function of region-search.

[Kenjiro NAKAYAMA]

I think the function to search the selected word withought any input is useful.
But it might be a good idea to set this function in .emacs.el or init.el by
users. So please judge this function should apply or reject.
I send the patch.

Sorr, since this is new functionality, I should have sent after the feature
freeze is over.

Hm...  so this would just use the default search engine to search for
whatever is in the region?  I'm not sure that that's a useful eww mode
command, but it might be a useful global command...

Yes, that's right. It is not big function, sorry...

Then, how about delete the key map and include the eww-search-region?
I want to know how much eww should provide its utilities like this function.

Emacs is in a feature freeze, but I think it sounds like a very useful
thing to be able to just set a point and mark in any buffer, hit
`M-s M-s', and then be presented with the eww search results.  Others
will have to comment on the keystroke, though.

I would use this happily.  The default keystroke doesn't matter too
much: I'll probably use `F2' and I imagine most people will want it on a
single key.  So please commit something like it after the feature freeze.

Does anybody have an opinion on this feature?  I think it sounds useful,
but I have no idea what global keystroke we would want to bind this to.

We have the M-s prefix specifically for search-related commands, so
there's a lot of key-binding room.

I have no opinion on the feature.  But it should not be named `*-region-search'.  It does not search the region (IIUC).  It searches for the selected text.

This has now been tweaked slightly and bound globally to `M-s M-s'.

Although perhaps something more should be done for Emacsen that doesn't
have eww available (i.e., without libxml2 support), but I don't know what.

A binding in M-s, yes, but M-s M-s should be kept for a "very common
kind of search", and I'm not convinced "pass it to eww" is
common enough.

Sure.  Uhm...  what would be a good mnemonic?  `M-s M-w' for "web"?  And
it's kinda easy to type.

Again, please rename the command.  The name is misleading.
The command neither searches the region nor searches for the
region (which would anyway be meaningless, from point).
It searches a buffer (I assume) for the text in the region.

People checking command names (via apropos commands or
completion matching, for example) looking for commands
that do something to the region can stumble on this.
(And people looking for a command that searches for the
selected text are unlikely to find it.)

A guess is that this was named by someone for whom
English is not the first language.  "Search X" is not
the same as "search for X".

It's not called that.

Great.

(I just saw that this thread is cc'd to emacs-devel.  Why?)
