eww and bookmarks

eww and bookmarks

[Boruch Baum]

For tinfoil-hat reasons, I'm hesitant about the idea of having a single
bookmark list for both local and network resources, and both emacs and
non-emacs launching. I don't want a situation where there might be
uncertainty which program is about to be launched or whether the network
is going to accessed and what follow-on 'stuff' my device will end up
doing.

That doesn't mean I oppose the notion of a single 'grand unified'
bookmark list, just that I would want some clear indication in advance
of what is about to happen should I open any specific link.

Maybe what would be sufficient for those concerns would be a pair of
visual cues: one for 'local/network', and a second for 'emacs/external'.
Then an interested user could query a bookmark's details for further
information, or just click-through. The visual cues might not even need
to take up additional screen space: maybe it would be sufficient to
underline network bookmarks, and to italicize bookmarks that launch
external programs.

I'm not sure just what you're replying to,
but different bookmark types can be created.

So sure, you could have any number of different
kinds of bookmarks for URLs or whatever.  And,
at least with Bookmark+, you can have different
types look different in the displayed bookmark
list.  And you can sort that list by type.

eww and bookmarks

Is there any reason why eww doesn't use bookmark.el? I could not 
found any explanation in eww.el nor the info documentation of 
Emacs. 

I'd prefer to have all my bookmarks available in a single buffer 
and managed in a single place; And I am happy so far with 
bookmark.el for usual bookmarks. Are you interested in eww to 
support bookmark.el (could be through a customization variable for 
example)?

This has come up before.  See thread "EWW improvements:
open in new buffer, tags, quickmarks, search engines, ..."

If you use Bookmark+ then you can create and use
ordinary Emacs bookmarks for EWW, not the EWW
pseudo-bookmarks.  By "ordinary" I mean that they
are like other bookmarks, show up in your bookmarks
list, are jumped to in the usual way, etc.

BTW, have you had a look at the discussion there?  Any opinion?

How should the bookmarks behave?  Should they be exact counterparts of
eww bookmarks?  Should they be linked to eww, or should it be possible
to open them also with another browser (e.g. w3m).

Finally, what should I specify as `defaults' list for the name
suggestions available when you are prompted for a name for a new
bookmark?  Just the url?

TIA,

Michael.

Yes, I read that thread. My use case is the same as the one of the 
OP of the thread you referenced: Being able to bookmark a web page 
and visit that page again in a different Emacs session, using the 
usual commands defined in bookmark.el (if using eww bookmarks, I 
would have to learn new kebindings and list bookmarks in different 
buffer than *Bookmark List*).
 
By the way, I can't imagine installing a third-party library for 
such a simple feature.
 
> How should the bookmarks behave?  Should they be exact

I went through what eww info manual says on bookmarks and used 
those bookmarks once to understand what is the provided feature; I 
can't find anything not available from standard bookmarks. Can you 
give details on what would be lost if eww used bookmarks.el?

May be use `browse-url-default-browser`, but it's a different 
discussion IMOH; The current need is to make the user life simpler 
with a single place to search their bookmarks and don't ask them 
to learn a second set of key bindings, manage a new file 
containing bookmarks and configure news hooks in case they want to 
customize their bookmark list appearance...

Note that in the same direction there's a proposal to base 
bookmark list on `tabulated-list-mode` 
https://lists.gnu.org/archive/html/bug-gnu-emacs/2020-01/msg01319.html.

An HTML document may have a "title" element; Isn't it possible to 
use the value of that element when available? And the URL 
otherwise.

I apologize I've not found time to check your patch right now; 
I'll try it in the forthcoming days.

Re: eww and bookmarks

[Alfred M. Szmidt]

I haven't followed the discussion closely, so might have missed things
-- the addition of bookmarks for URLs would be very nice.

Isn't this very easily done though, both so that it works for the case
of eww, but also (which I think is important, in the generic case),
simple untested hackery, in .emacs.bmk we have:

("The GNU Operating System and the Free Software Movement"
 (url . "http://www.gnu.org/")
 (handler . browse-url-bookmark-jump))

Then browse-url-bookmark-jump is simply:

(defun browse-url-bookmark-jump (bmk)
  (let* ((url (bookmark-prop-get bmk 'url))
         (buf (save-window-excursion (browse-url url) (current-buffer))))
    (bookmark-default-handler
     `("" (buffer . ,buf) . ,(bookmark-get-bookmark-record bmk)))))

Those that like EWW would already be doing:

  (setq browse-url-browser-function 'eww-browse-url)

And then the equivalent browse-url-bookmark-make-record (e.g,
Info-Info-bookmark-make-record) function for setting, which is left as
a excersie for the reader -- or I can make a patch.  This might not
work of course if you are outside of the context of Emacs.

It would be strange if eww implemented its own bookmarking
functionality, when all of this is already simple to add.

I've been watching this thread, trying to determine if any new functionality would need to be added to bookmark.el in order to support EWW bookmarks.

So far, it looks like it can all be implemented using existing functionality in bookmark.el, using `bookmark-make-record-function' and a handler function, as per above.

If it turns out that anything new is needed, please say so.  bookmark.el should be able to supply generic bookmarking functionality to other packages, and I'm happy to help with that if further extension is needed.

Best regards,
-Karl

No one said it is hard ;-)  It's only left to decide how the handler

Is there really a generic case that creates bookmarks with an url field?

Ok, so you would make the handler call `browse-url-browser-function',
and not eww unconditionally.  I think I would prefer that behavior, too.

I already have one, but thanks for your input.

Just to be clear: this is where we are, eww has it's own bookmarking
mechanism, for a long time.

   No one said it is hard ;-)  It's only left to decide how the handler
   should behave.

The most natural behaviour would be to use browse-url-browser-function
-- since that is what everything else in GNU Emacs would normally use
to browse URL's.

   Is there really a generic case that creates bookmarks with an url
   field?

I'm not sure what you mean generic here?

Adding a new entry is possible, and even a supported case by
bookmark-make-record.  Any web browser that can set a bookmark
(i.e. anything in Emacs) would ofcourse need to agree on using that
specific entry.

   Just to be clear: this is where we are, eww has it's own
   bookmarking mechanism, for a long time.

That is a pity, but not one that is impossible to change.  The
bookmarking code in eww, could be replaced with the same functionality
as used in rest of Emacs and still I think be compatible with the
current way eww does bookmarks from a users point of view.

Some sort of hackery maybe to convert existing bookmarks to
bookmark.el format might be useful though.

Lars, we are wondering why you implemented a separate bookmarking
mechanism for eww instead of relying on the existing Emacs bookmarks.
Could you give us some background?  Do eww bookmarks offer some feature
that vanilla bookmarks don't support?  Or did you just want to have
something separate?

TIA,

Michael.

There's two reasons -- I had no idea that bookmark.el existed.  Well,
OK, that's the main reason.

The other is that ever web browser has a bookmark facility, and that's
not usually mixed in with, well, other stuff.

FWIW, I would like to use bookmarks for EWW, and I'd like those
bookmarks to *always* use EWW, and my `browse-url-browser-function` is
definitely not EWW but Firefox.

Emacs bookmarks don't just refer to a particular "page" but also
remember the place within that page (by remembering surrounding text)
and I think this part can only work if we go back with EWW.

Since the page was originally viewed in EWW the corresponding bookmark
*by default* should use EWW as well.  We can add a configuration option
to make it obey `browse-url-browser-function` if you want, but it should
not be the default behavior: a bookmark is supposed to bring you back to
where it was created, so if it was created in EWW it shouldn't send you
to Firefox.

+1

I was one of the people who asked for this feature at all.  My main
browser is Firefox, but in this particular case, I prefer eww because of
the incremental search/swiper (the page is a poorly formatted
documentation for certain library).

Opening the bookmark in firefox would completely defeat the purpose of
having it at all.

It's not the question whether I like eww or not (in fact, I don't).  The
thing is that I want to view some pages in firefox and others in eww.

Wouldn't defadvice with browse-url-browser-function bound to

That sounds like confusing behaviour, you would never know what your

Firefox, sometimes it might be a third thing?

AFAIK we currently don't have any code which generates bookmarks that
are passed to Firefox.  [ And Firefox has its own bookmarks for that.  ]

If we add this, this new vanilla Emacs bookmark type would be the only
kind of Emacs bookmarks including an url, so the behavior would be
always the same, it would just be configurable - or do I miss something?

What do you others think?  Do you want to see some of those features in
Emacs (apart from 1, which I think is not controversial and definitely
"must have")?

I think for w3m it could work as well, no?

But here we have a difference to eww bookmarks: AFAIK they don't save a
position along with the url.

I don't think anything would be lost.  My setup is very different (I'm
saving Internet-related bookmarks in firefox and consult them from
Emacs), so I want to find out what a behavior users expect/prefer.

Yes, but we need to specify some handler for the bookmarks, so it's
something to decide now.

I had installed something that treated a different problem that appeared

Coming back to this: I've got a problem with the implementation: because
eww retrieves asynchronously, jumping to the bookmark's position does
not work, because when that is done, the buffer is not yet filled and
rendered.  I don't see a way to make this work that is not either an
ugly hack or would involve changing and refactoring parts of the eww
code.  I don't really feel qualified.

What would be needed at least would be to replace the hardcoded
#'eww-render in the `url-retrieve' call in `eww' with a newly introduced
variable `eww-render-function' I could bind.  Or is there a better way?

Here is what I have so far:

Yes, I know about the hook.  But just binding it will not be enough
because the binding will be gone when it is consulted.  We would have to
add a self-removing function at least to the local binding of the hook.
That's what I would call a hack.

Didn't yet look at your other points, but thank you so far.

eww-after-render-hook does not seem to be useable because it runs in the
wrong buffer at the wrong time.

I hit the issue when implementing the following use-case:

1) Open login page URL
2) Automatically fill in username and password
3) Automatically submit the login form

My workaround something like this:

(defun login-fn-delayed ()
  (with-current-buffer "*eww*"
    (fill-in-username-and-password)
    (submit-login-form)))

(defun login-fn ()
  (interactive)
  (eww some-url)
  (run-with-timer "1 sec" nil 'login-fn-delayed))

It would be nice, if there was no need for run-with-timer and no need
for (with-current-buffer "*eww*"...).

Why?  It's what minibuffer-with-setup-hook does, for example.

If you really wanted to you could add a new hook/variable to provide the
desired semantics directly, but it's not absolutely necessary.

That can use `unwind-protect' because it has not to wait an undefined
period of time (until the page has been retrieved asynchronously).

So we would have to consider what could happen if the user aborts
loading the page, the url can't be retrieved, there is an intermediate
error, and such.  That's why I think using the callback of
`url-retrieve' would be better/cleaner.

Could you store the desired callback or other values in eww-data?

I guess.  But it's not the solution I would prefer.

BTW, `eww-render' already has a POINT argument.  Not quite enough for
our purpose, though.

Another alternative: we could make the callback arg of the
`url-retrieve' call in `eww' a closure remembering the value of
`eww-after-render-hook'.  That would make binding the hook variable work
as expected.

Okay, but that's not consistently followed.  C-h f eww RET:

  If called with a prefix ARG, use a new buffer instead of reusing
  the default EWW buffer.

Is the proposed bookmark.el support not meant to supersede EWW's current
bookmark system?

Anyway, what about eww-browse-bookmark-function?

That's what it looks like to me, but you can obviously leave it alone
for now.

In the long run, maybe.  I will not do that now.  Personally, I
don't feel bad about eww having a separate bookmarking mechanism like
any other browser.

Re: eww and bookmarks

[Adam Porter]

Hi,

Having recently put together a new package that uses bookmarks to
restore windows and buffers, Burly[0], I tested bookmarks with EWW
buffers, expecting them to be bookmarkable with Emacs bookmarks, but I
found that they aren't.  Then I found this thread[1] from June about
Michael's patch, which sounds great, but it doesn't seem to have been
applied yet.

Is there any chance it can make it into Emacs 28?  It seems a shame for
EWW buffers to not work with Emacs's own bookmark system.

Thanks to Michael, et al for your work on this patch.

FWIW, Bookmark+ provides normal bookmarking with EWW.

It sounded like a good idea to me, but looking at the thread, there were
some problems with an async callback?  I've just skimmed it.  But I'm
for using the normal Emacs bookmark regime in eww, if possible.

AIUI the issue is with restoring the position within a restored EWW
buffer.  That's certainly desirable, but IMHO it needn't prevent the
patch from being merged; not all major modes even have bookmark support,
and not all bookmark handlers always restore the buffer position
correctly, anyway (e.g. if the file has changed sufficiently since being
bookmarked).

As for fixing that issue, I have two thoughts:

1.  In Burly I faced a similar problem.  I used a solution similar to
one mentioned in the thread: I added a self-removing function to a hook
that's run after the bookmark is loaded.  In the thread, that solution
was not exactly rejected[0]; I think it's probably a good-enough
solution, especially by adding to the hook buffer-locally and wrapping
the hook-removal in an unwind-protect.

2. An alternative mentioned in the thread[1] was to use url-retrieve's
callback to move point after the buffer is rendered.  If there are any
problems with that solution, it doesn't seem that any were mentioned.

(+1 to the "Thanks to Michael" there!)

From what I see of the thread, Michael's patch doesn't seem ready to apply yet.  The most recent version is in this message...

...but in that message he refers to some problems it still has.  There is followup discussion in the thread in which he mentions further improvements, but no revised patch as far as I can see.

So currently I'm not sure what patch we would review.  Michael, if you have a newest & working version, please post.  (Or if you already have posted it, then please let me know.  The way I searched was by looking at every subsequent post from you, in that thread, since the above message.)

Best regards,

Would string-trim for this?
