69 @dfn{EWW}, the Emacs Web Wowser, is a web browser for GNU Emacs. It
70 can load, parse, and display various web pages using @dfn{shr.el}.
71 However a GNU Emacs with @code{libxml2} support is required.
78 @vindex eww-search-prefix
81 You can open a URL or search the web with the command @kbd{M-x eww}.
82 If the input doesn't look like a URL or domain name the web will be
83 searched via @code{eww-search-prefix}. The default search engine is
84 @url{https://duckduckgo.com, DuckDuckGo}. If you want to open a file
85 either prefix the file name with @code{file://} or use the command
86 @kbd{M-x eww-open-file}.
90 @findex eww-copy-page-url
94 If loading the URL was successful the buffer @file{*eww*} is opened
95 and the web page is rendered in it. You can leave EWW by pressing
96 @kbd{q} or exit the browser by calling @kbd{eww-quit}. To reload the
97 web page hit @kbd{g} (@code{eww-reload}). Pressing @kbd{w}
98 (@code{eww-copy-page-url}) will copy the current URL to the kill ring.
101 @vindex eww-download-directory
104 A URL under the point can be downloaded with @kbd{d}
105 (@code{eww-download}). The file will be written to the directory
106 specified in @code{eww-download-directory} (Default: @file{~/Downloads/}).
109 @findex eww-forward-url
110 @findex eww-list-histories
115 EWW remembers the URLs you have visited to allow you to go back and
116 forth between them. By pressing @kbd{l} (@code{eww-back-url}) you go
117 to the previous URL. You can go forward again with @kbd{r}
118 (@code{eww-forward-url}). If you want an overview of your browsing
119 history press @kbd{H} (@code{eww-list-histories}) to open the history
120 buffer @file{*eww history*}. The history is lost when EWW is quit.
121 If you want to remember websites you can use bookmarks.
123 @findex eww-add-bookmark
124 @findex eww-list-bookmarks
128 EWW allows you to @dfn{bookmark} URLs. Simply hit @kbd{b}
129 (@code{eww-add-bookmark}) to store a bookmark for the current website.
130 You can view stored bookmarks with @kbd{B}
131 (@code{eww-list-bookmarks}). This will open the bookmark buffer
132 @file{*eww bookmarks*}.
134 @findex eww-browse-with-external-browser
135 @vindex shr-external-browser
136 @vindex eww-use-external-browser-for-content-type
138 @cindex External Browser
139 Although EWW and shr.el do their best to render webpages in GNU
140 Emacs some websites use features which can not be properly represented
141 or are not implemented (E.g., JavaScript). If you have trouble
142 viewing a website with EWW then hit @kbd{&}
143 (@code{eww-browse-with-external-browser}) inside the EWW buffer to
144 open the website in the external browser specified by
145 @code{shr-external-browser}. Some content types, such as video or
146 audio content, do not make sense to display in GNU Emacs at all. You
147 can tell EWW to open specific content automatically in an external
148 browser by customizing
149 @code{eww-use-external-browser-for-content-type}.
154 @findex eww-view-source
156 @cindex Viewing Source
157 You can view the source of a website with @kbd{v}
158 (@code{eww-view-source}). This will open a new buffer
159 @file{*eww-source*} and insert the source. The buffer will be set to
160 @code{html-mode} if available.
162 @findex url-cookie-list
165 EWW handles cookies through the @ref{Top, url package, ,url}.
166 You can list existing cookies with @kbd{C} (@code{url-cookie-list}).
167 For details about the Cookie handling @xref{Cookies,,,url}.
169 @vindex eww-header-line-format
171 The header line of the EWW buffer can be changed by customizing
172 @code{eww-header-line-format}. The format replaces @code{%t} with the
173 title of the website and @code{%u} with the URL.
175 @c @vindex shr-bullet
176 @c @vindex shr-hr-line
177 @c @vindex eww-form-checkbox-selected-symbol
178 @c @vindex eww-form-checkbox-symbol
179 @c EWW and the rendering engine shr.el use ASCII characters to
180 @c represent some graphical elements, such as bullet points
181 @c (@code{shr-bullet}), check boxes
182 @c (@code{eww-form-checkbox-selected-symbol} and
183 @c @code{eww-form-checkbox-symbol}), and horizontal rules
184 @c @code{shr-hr-line}). Depending on your fonts these characters can be
185 @c replaced by Unicode glyphs to achieve better looking results.
187 @vindex shr-max-image-proportion
188 @vindex shr-blocked-images
189 @cindex Image Display
190 Loading random images from the web can be problematic due to their
191 size or content. By customizing @code{shr-max-image-proportion} you
192 can set the maximal image proportion in relation to the window they
193 are displayed in. E.g., 0.7 means an image is allowed to take up 70%
194 of the width and height. If Emacs supports image scaling (ImageMagick
195 support required) then larger images are scaled down. You can block
196 specific images completely by customizing @code{shr-blocked-images}.
198 @vindex shr-color-visible-distance-min
199 @vindex shr-color-visible-luminance-min
201 EWW (or rather its HTML renderer @code{shr}) uses the colors declared
202 in the HTML page, but adjusts them if needed to keep a certain minimum
203 contrast. If that is still too low for you, you can customize the
204 variables @code{shr-color-visible-distance-min} and
205 @code{shr-color-visible-luminance-min} to get a better contrast.
207 @node History and Acknowledgments
208 @appendix History and Acknowledgments
210 EWW was originally written by Lars Ingebrigtsen, known for his work on
211 Gnus. He started writing an Emacs HTML rendering library,
212 @code{shr.el}, to read blogs in Gnus. He eventually added a web
213 browser front end and HTML form support. Which resulted in EWW, the
214 Emacs Web Wowser. EWW was announced on 16 June 2013:
215 @url{http://lars.ingebrigtsen.no/2013/06/16/eww/}.
217 EWW was then moved from the Gnus repository to GNU Emacs and several
218 developers started contributing to it as well.
