If you need help with something or have some cool ideas to share, please post it here instead of the issue, this is more like forum page for EAF! ;)

in every page (forum, blog, microblog...) where you can input text there's the same problem

if you don't have a zeronet installation you can access through proxy and try "Filter: site name" on the top-left side of the first aggregative page

an introduction on zeronet structure is on ZeroNet Developer Documentation » https://zeronet.io/docs/site_development/getting_started/

Hi guys! I could not find how to visit a new url within the same tab, i.e. without opening a new tab. eaf-open-browser always opens a new tab (if the new url does not match a url of a currently open buffer). You have an idea?

open_url in core/browser.el

dalanicolai Jan 16, 2021

Ah, I guess you were mistaking. The command I was looking for is (insert_or_)edit_url. Don't know how I overlooked that one. Anyway, thanks to your hint I finally found it.

Should the pdf-viewer work with djvu? Because here, although the eaf pdf-viewer opens djvu (and the the extension is in the default eaf-pdf-extension-list), it does not show anything.

@luhuaei any ideas?

I see the pymupdf support extensions don't has djvu, and use mupdf open djvu file failed.

So use pdf-viewer open djvu file will not show anything. @dalanicolai

Sounds good, I've removed djvu from eaf-pdf-extension-list to prevent future confusion.

Hello again!

I am a Spacemacs user, and I have noticed that since the witch to epc, ESC does not work anymore to exit from insert state (e.g. in the browser). Can you (help me to) fix that?

dalanicolai Feb 8, 2021

Okay, so this part is fixed by not requiring eaf-evil (as suggested here)

Also beside the SPC-leader key, Spacemacs uses , as a major-mode leader key.

I had added functionality to emulate the leader key in EAF, similar to how you achieve that for SPC.
So the code looks like this:

      (setq eaf-evil-leader-for-major-keymap (make-sparse-keymap))
      (define-key eaf-evil-leader-for-major-keymap (kbd "h") 'eaf-open-browser-with-history)
      (define-key eaf-evil-leader-for-major-keymap (kbd "d") 'eaf-toggle-dark-mode)
      (define-key eaf-evil-leader-for-major-keymap (kbd "s") 'eaf-search-it)
      (add-hook 'evil-normal-state-entry-hook
                (lambda ()
                  (when (derived-mode-p 'eaf-mode)
                    (define-key eaf-mode-map (kbd "C-,") eaf-evil-leader-for-major-keymap))))

      (define-key key-translation-map (kbd ",")
        (lambda (prompt)
          (if (derived-mode-p 'eaf-mode)
              (if (and (string= eaf--buffer-app-name "browser")
                       (eaf-call-sync "call_function" eaf--buffer-id "is_focus"))
                  (kbd ",")
                (kbd "C-,"))))))))

This worked when using dbus (when I used just eaf-call without the -sync). However, currently when I use describe-key for , in an EAF app, it tells me it is bound to eaf-send-key.

So I hope you could (help me also with) get this functionality back. 🙏

dalanicolai Feb 8, 2021

Ah, okay I found this problem also. I see you have changed the condition in the if clause:

  ("browser" (if (string= (eaf-call-sync "call_function" eaf--buffer-id "is_focus") "True")
                           (kbd "SPC")
                         (kbd eaf-evil-leader-key)))

So by changing mine similarly, it does work now.

There is a dependency on f.el (http://github.com/rejeep/f.el) since the following commit

commit 81b59fc02f9c2f3b74afb63e096af448a9a5b06f

    add eaf-open-pdf-with-history function (#690)

as it has introduced a call to (f-write-text "" 'utf-8 pdf-history-file-path)
So there is a need to download and install f.el from melpa (or other repository).

install_eaf.sh on Ubuntu failed with the error: ./install-eaf.sh: 9: Syntax error: "(" unexpected

The error was due to POSITIONAL=() at line number 9 in install-eaf.sh

Hi, thanks for writing EAF! I'm using the browser and pdf viewer and they are working really well! The only problem I have experienced so far is that the browser buffer sometimes stops responds to any keybindings at all. Even C-x and C-c do not work. I have to click on the modeline with my mouse in order to get out of this mysterious state, and then the keybindings start working again. Is this a bug or a feature that I don't understand?

Thanks!

You can uncomment this line

emacs-application-framework/core/view.py

Line 111 in 249b6c9

# print(time.time(), event.type())

to debug what's wrong. ;)

Sorry for the radio silence. I tried uncommenting that line and reinstalling eaf. However, I don't see any output in the terminal I launched emacs from. Where is the output supposed to show up?

Thanks for your continued help so far, Andy and Matthew! I've spent a long time debugging and haven't gotten anywhere. Since both XFCE and KDE are listed as supported window managers, I don't understand why I can't get the keyboard focus to work without using the eaf-wm-focus-fix-wms workaround (the mouse warping behavior of this workaround is IMHO more annoying than not getting keyboard events at all). I wonder if it has something to do with the versions of the libraries I am using?

pyqt5: 5.15.4
xserver: 1.20.11
XFCE: 4.16
KDE: 5:112

Just for reference I'm also including what I did for debugging, in case it is useful somehow.

I used "xwininfo -tree" to print all windows associated with emacs. I managed to find the window ids for the EAF browser window and the normal emacs window this way.

I used "xev -id -event keyboard" to monitor the keyboard events for the emacs window and the EAF window. I confirmed that I do indeed see the keyboard events for each window this way. It also seems like the id of the EAF window changes every once in a while.

What I observe in this setup is that I don't even need to click on the EAF window for the focus to switch to it. I simply have to hover my mouse over the EAF window, and then all keyboard events will go to it. If I then move the mouse back to a regular emacs window, emacs starts getting keyboard events again. I guess you guys are already aware of this as it's the basis for the mouse warping work-around.

I tried to change the line "(shell-command-to-string (format "wmctrl -i -a $(wmctrl -lp | awk '$3==%s {print $1; exit}')" (emacs-pid)))" in eaf.el to several other approaches to change window focus. I first passed an explicit window id to "wmctrl -i -a" to rule out any possibility that the window id wasn't computed correctly. I also tried "xdotool windowactivate" and "xdotool windowfocus" with explicit window ids. None of this worked.

I finally figured out why my emacs was never capturing keyboard events when my mouse cursor is over an EAF buffer. It had nothing to do with my window manager. My emacs is compiled from the git repo and I had used the option "--with-x-toolkit=lucid" in the configure script. Once I removed that option (which means using the default gtk3 toolkit) and recompiled, EAF started working as expected. I don't have to use the eaf-wm-focus-fix-wms workaround either.

My guess is that EAF probably won't work with anything other than --with-x-toolkit=gtk3? You can actually check for this using the elisp variable "system-configuration-features". It will contain the string "GTK3" if using gtk3 x-toolkit, otherwise it will contain "LUCID" or "ATHENA". It would be good to warn the user in the latter case so that they won't go on a wild goose chase like I did.

Hi! I'm a relatively new user to Emacs, having migrated over from Neovim a few months ago. I quickly took to seeing how many of my old customizations I in Neovim I could bring over to Emacs, with Evil-mode and things associated with it. I can safely say that I've fallen head over heels for Emacs and can't see myself going back to Neovim any time soon. EAF is incredible (though I have some questions/issues(?) to report, which is part of why I came here) and I am excited beyond words to see where this amazing piece of software goes next.

Hello, I am not sure how to modify eaf-mode-map*. I want my setting for M-o not be touched by EAF. So I have, in my init.el

 (setq eaf-mode-map*
		  (let ((map (make-sparse-keymap)))
		    (define-key map (kbd "M-o") #'ace-window)
		    (define-key map (kbd "C-h m") #'eaf-describe-bindings)
...
)

However, under eaf-browser, M-o still gives eaf-py-proxy-eval_js.

I've checked and C-h v eaf-mode-map* correctly shows my binding:

eaf-mode-map* is a variable defined in ‘eaf.el’.

Its value is shown below.

Keymap for default bindings available in all apps.

Value:
(keymap
 (return . eaf-send-key)
 (backspace . eaf-send-key)
...
 (27 keymap
     (91 . eaf-share-path-or-url)
     (47 . eaf-get-path-or-url)
     (39 . eaf-toggle-fullscreen)
     (111 . ace-window)))
