Hello:


I try newest xwidget feature today, and show error:

This could happen if the version of WebKitGTK installed on your system
is buggy, and errors out trying to start a subprocess through
Bubblewrap sandboxing.  You can avoid the crash by setting the
environment variables SNAP, SNAP_NAME and SNAP_REVISION, which will
make WebKit use GLib to launch subprocesses instead.

What does SNAP mean?  any suggest value to three variables?

It tricks WebKitGTK into thinking it's running in Snap, which prevents
it from going down the buggy code path.

Any value should suffice, but all three variables must be set.  For
instance, you can do:

  $ SNAP=1 SNAP_NAME=1 SNAP_REVISION=1 emacs

Thanks.

By the way:
1. header-line looks ugly when tab-line is enabled, what about add a custom variable.
2. I can not open a link when left-click with mouse,  any way to deal with it ?
3. right-click mouse will pop menu, but it's position can outside emacs.

Could you give me a link to the site you are using?  Thanks.

That problem is something I've been trying to solve, but so far haven't
come up with a solution for yet.

I'll keep you posted on the progress though.

Open:

1. http://cn.bing.com/search?q=emacs 
2. https://www.baidu.com/s?ie=utf-8&f=8&rsv_bp=1&rsv_idx=1&tn=baidu&wd=emacs

and I can not click most search results links

Thanks.  The links in those pages work here, but this stuff tends to
vary a great deal depending on the version and configuration of
WebKitGTK being used, so I suspect some kind of behind-the-scenes
filtering of the type that WebKit likes to do by default.

Can you tell me if these links open on your system with another
WebKitGTK based browser such as Epiphany?  (In Epiphany, also verify
that Settings -> General -> Block Popup Windows is enabled before
performing this test, as this is the default setting of a
WebKitWebView.)

Alternatively, could you try this patch and see if it resolves your
problem?

That's intended behavior.  You'll notice that Baidu also opens search
results in a new tab, in other browsers.

Lars, could you install this patch?  Thanks.

How to remove fringes of xwidget window? I try the below code, seem to not work.

(add-hook 'xwidget-webkit-mode-hook
          #'eh-xwidget-webkit-mode-hook)

(defun eh-xwidget-webkit-mode-hook ()
  (setq-local left-fringe-width 0)
  (setq-local right-fringe-width 0))

You should call `set-window-buffer' after changing `left-fringe-width'
or something.

I don't remember the details, but those variables don't take effect
immediately!  Thanks.

The below code works, thanks!

(defun eh-xwidget-webkit-mode-hook ()
  (setq-local left-fringe-width 0)
  (setq-local right-fringe-width 0)
  (set-window-buffer (selected-window) (current-buffer)))

It will open links in new tab, no matter Block Popup Windows is enable or not.
