dwb is an extremely fast, lightweight and flexible web browser using the webkit engine. It is customizable through its web interface and fully usable with keyboard shortcuts.

Installation

The dwb package can be found in the official repositories and can be installed with pacman.

# pacman -S dwb

There are also other versions in the AUR: dwb-gitAUR, dwb-gtk3AUR, and dwb-gtk3-gitAUR.

Basic usage

Starting from a fresh configuration, use Template:KeypressTemplate:Keypress to open the Keys page. As you can see from there, most bindings are borrowed from Vim and Emacs.

Use Template:Keypress to access the command prompt. You can use Template:Keypress to auto-complete.

Read the man page for more details and enable the auto-completion option in the settings to help you learn the bindings.

$ man dwb

Navigation

o         = enter url
O         = enter url in new tab
f        = spawn hints next to each hyperlink. Type the letter to follow the link.
F        = spawn hints in new tab
H         = back
L         = forward
J        = go to next tab
K        = go to previous tab
'n'+T      = goto 'n' tab
d         = close tab
u         = undo close tab
ctrl+S         = stop
r         = reload
R         = reload ignoring cache
i         = toggle_insert_mode   (Esc works to go back to command mode much like vim)
gi        = go to the first input field and enter insert mode
ctrl+e = open editable field in external editor
;d      = download via hints

Page Movement

j         = scroll down
k         = scroll up
h         = scroll left
l         = scroll right
ctrl+b    = scroll page up
ctrl+f    = scroll page down
gg     = go to top
G         = go to bottom
/         = find in page
n         = repeat find forward
N         = repeat find backwards
+         = zoom_in
-         = zoom_out
=         = reset to 100%

Other

M         = save bookmark (bookmarks are saved in ~/.config/dwb/default/bookmarks
xb        = show/hide status bar
ZZ        = exit
:         = enter command
Esc       = back to normal mode
ctrl+n    = back to normal mode

dwb features some interesting bindings:

Configuration

Almost everything can be configured from the Settings page. You can access it with Template:KeypressTemplate:Keypress by default.

The configuration files are stored in $XDG_CONFIG_HOME/dwb/ (usually ~/.config/dwb/).

Search engines

Use Template:KeypressTemplate:Keypress to create a search engine from the first input field on the web page. Use Template:Keypress to switch between fields. Then enter a keyword.

Now you can use the keyword in the URI prompt to search directly on the corresponding website.

The first entry in $XDG_CONFIG_HOME/dwb/searchengines will be the default search engine.

Custom keybinds

You can create custom key bindings by editing file custom_keys in the profile directory. This is ~/.config/dwb/default by default. All keysyms which don't emit (multi)byte characters, must be enclosed in @. One keybind can execute multiple dwb commands. These commands execute in same order as they are defined in bind, and must be separated by ;; separator. If the keybind's chord is already bound by dwb, it might be ignored (behaviour is not consistent). In such case one can try to check, whether there is collison with binds defined in ~/.config/dwb/keys and try to unbind the chord there (eg set it to nothing). Any running dwb instance will owerwrite keys file on exit, so remember to do your modifications while dwb is not runing or use default dwb interface (S k).

~/.config/dwb/default/custom_keys
Control w           :close_tab
Control @Page_Up@   :focus_prev
Control @Page_Down@ :focus_next


Extensions

dwb features an extension manager as a separate executable, dwbem. To list all officially available extensions, use:

dwbem -a
   Available extensions:
   - adblock_subscriptions
   - autoquvi
   - contenthandler
   - downloadhandler
   - formfiller
   - googlebookmarks
   - googledocs
   - grabscrolling
   - multimarks
   - perdomainsettings
   - pwdhash
   - requestpolicy
   - simplyread
   - speeddial
   - supergenpass
   - unique_tabs
   - userscripts
   - whitelistshortcuts

Read the man page for more details.

Adblock

dwb features an Adblock extension. Install it with

$ dwbem -i adblock_subscriptions

Restart dwb, use the adblock_subscribe command and choose your favorite filter (avoid using more than one filter to prevent duplicate entries that make the adblocker much slower).

Userscripts

dwb can execute .js or .sh scripts put in ~/.config/dwb/userscripts/. Make sure they are executable:

chmod +x ~/.config/dwb/userscripts/myscript.js

Below are some example scripts, see dwb userscripts snippets for more:

Fast-forward

Opera features a neat key binding which allows users to load to ne next/previous logical page by incrementing/decrementing the last URI digit. This is very useful for forum threads, documentation, and articles spread over several pages.

This feature can be implemented with a simple javascript function and bound to custom keys:

custom_keys
]:exja (function(){var e=document.querySelector("[rel='next']");if(e){location=e.href;}else{var f=document.getElementsByTagName("a");var i=f.length;while((e=f[--i])){if(e.text.search(/(\bnext\b|^>$|^(>>|»)$|^(>|»)|(>|»)$|\bmore\b)/i)>-1){location=e.href; break;}}}})();
[:exja (function(){var e=document.querySelector("[rel='prev']");if(e){location=e.href;}else{var f=document.getElementsByTagName("a");var i=f.length;while((e=f[--i])){if(e.text.search(/(\b(prev|previous)\b|^<$|^(<<|«)$|^(<|«)|(<|«)$)/i)>-1){location=e.href;break;}}}})();

Alternatively, the navtools extension provides the same functionality and more, such as going up one directory, or loading the root URI.

startup-noautoreload

Prevents previously-opened tabs from reloading all at once after a restart.

~/.config/dwb/userscripts/startup-noautoreload.js
//!javascript
// prevents previously-opened tabs from reloading all at once after a restart.
execute("set load-on-focus true");

var sigId = signals.connect("navigation", function(wv) {
        if (wv == tabs.current)
        {
                    execute("set load-on-focus false");
                            signals.disconnect(sigId);
                                }
});

youtube-mplayer

Opens YouTube videos with mplayer (requires mplayer and youtube-dl).

~/.config/dwb/userscripts/youtube-mplayer.js
//!javascript 
// opens YouTube videos with mplayer.
var regex = new RegExp("http(.*)://www.youtube.com/watch\\?(.*&)*v=.*");

signals.connect("navigation", function (wv, frame, request) {
  if (wv.mainFrame == frame && regex.test(request.uri)) 
    system.spawn("sh -c 'mplayer \"$(youtube-dl -g " + request.uri + ")\"'");
  return false;
});

Stylesheets

Stylesheets can be defined in the Settings page under user-stylesheet-uri file:///home/tux/.config/dwb/stylesheet.css

Troubleshooting

HTML5 audio and video does not work

Make sure you have the following GStreamer packages installed:

# pacman -S --needed gstreamer0.10 gstreamer0.10-bad gstreamer0.10-bad-plugins gstreamer0.10-base gstreamer0.10-base-plugins gstreamer0.10-good gstreamer0.10-good-plugins gstreamer0.10-ugly gstreamer0.10-ugly-plugins

Search engines always search for undefined

If you are always searching for undefined even with the searchengine-submit-pattern option set, then you should edit $XDG_CONFIG_HOME/dwb/searchengines and adapt the URIs to match your searchengine-submit-pattern.

Fuzzy font in Github

Add this in your ~/.config/fontconfig/fonts.conf inside the fontconfig-tags:

 <selectfont>
   <rejectfont>
     <pattern>
       <patelt name="family">
         <string>Clean</string>
       </patelt>
     </pattern>
   </rejectfont>
 </selectfont>
