w3m

ELinks
Lynx

w3m はテキストベースの Web ブラウザであり、more や [ [less]] w3m を使用すると、ターミナルエミュレータウィンドウを通じて Web ページを閲覧できます。さらに、w3m は、HTML をプレーンテキストにタイプセットするテキスト整形ツールとしても使用できます。

インストール

w3m パッケージをインストールして下さい。

使い方

こちらを参照 w3m(1)

設定

w3m は、ブラウザ内の設定メニューを使用するか、設定ファイルを直接変更することによって構成できます。

より高度なオプションの一部は設定メニューを使用して使用できないため、設定ファイル自体を編集することをお勧めします。

デフォルトでは、すべての設定ファイルは ~/.w3m にあります。

Tips and tricks

Vim keybinds

Replace ~/.w3m/keymap with a custom configuration.

URL hints

w3m supports qutebrowser-like link navigation, simply navigate to your config file and change the following line from display_link_number 0 to display_link_number 1.

And add keymap f COMMAND "RESHAPE ; LINK_BEGIN ; GOTO_LINK" and keymap F COMMAND "RESHAPE ; LINK_BEGIN ; TAB_LINK" to ~/.w3m/keymap.

ノート: While qutebrowser supports a variety of keys to select hints, in w3m you can only select links using the number keys.

Using kittens image protocol

Users of the kitty terminal emulator may chose to use its own graphics protocol.

To do so simply change the following lines in ~/.w3m/config:

inline_img_protocol 0
imgdisplay w3mimgdisplay

to:

inline_img_protocol 4
imgdisplay kitty

Searching

You can set wrap_search to 1, to allow searches to jump to the top after they have hit the bottom of all matches within a page.

You can set ignorecase_search to 1 to enable case insensitive searching.

ノート: Unlike other browsers and text editors, w3m has no option for smartcase searching.

Custom search engines

You can map keys to launch a CGI script that will capture your input and pass it onto a custom search engine, to do so first create a keybind inside ~/.w3m/keymap to launch your script:

keymap s COMMAND "SET_OPTION dictcommand=file:///cgi-bin/omnibar_google.cgi ; DICT_WORD"

And place omnibar_google.cgi inside your ~/.w3m/cgi-bin directory and giving it execute permission.

While the above script will return a Google result, you can use these kinds of scripts to search StackOverflow, GitHub, DuckDuckGo, Reddit and a bunch of other websites.

You can view similar scripts on GitHub.

Reader mode

Some webpages do not work well with w3m, be it because they use a lot of javascript or CSS to display most of their content. Very often you will have to scroll multiple pages just to get to the start of an article.

This can be mitigated by first passing the webpages through a reader mode program such as rdrview-git^AUR.

To do so add the following to ~/.w3m/keymap:

keymap R COMMAND "READD_SHELL 'rdrview $W3M_URL -H 2> /dev/null 1> /tmp/readable.html' ; LOAD /tmp/readdable.html"

Redirect URLs

~/.w3m/siteconf file is used to set some preferences depending on the website, such as: referrer and user agent.

It can also be used to redirect to lighter (both in terms of layout and bandwidth), more privacy respecting alternatives to websites.

In addition to this it can also be used to run certain CGI scripts.

~/.w3m/siteconf

url m!^https?://([a-z]+\.)?twitter\.com/!
substitute_url "https://nitter.net/"

url m!^https?://([a-z]+\.)?reddit\.com/!
substitute_url "https://safereddit.com/"

#url m!^https?://([a-z]+\.)?google\.com/!
#substitute_url "https://duckduckgo.com/lite/"

url m!^https?://([a-z]+\.)?imgur\.com/!
substitute_url "https://rimgo.pussthecat.org/"

url m!^https?://([a-z]+\.)?wikipedia\.com/!
substitute_url "https://wl.vern.cc/"

url "https://www.youtube.com/" exact
substitute_url "file:/cgi-bin/video.cgi?"
#substitute_url "https://yewtu.be/"

url "https://stackoverflow.com/" exact
substitute_url "https://ao.bloatcat.tk/"

url "https://www.reuters.com/" exact
substitute_url "https://neuters.de/"

url "https://fandom.com/" exact
substitute_url "https://breezewiki.pussthecat.org/"

url "https://medium.com/" exact
substitute_url "https://scribe.rip/"

url "https://web.archive.org/" exact
substitute_url "https://wayback-classic.net/"

Restore closed windows

Default w3m cannot reopen closed tabs, this can be added by binding the close tab button to echo the current URL of the tab to be closed to a text file, and binding another key to restore the latest URL added to the file, using a CGI script.

Inside ~/.w3m/keymap add:

keymap d COMMAND "EXTERN 'echo %s >> ~/.w3m/RestoreTab.txt' ; CLOSE_TAB"
keymap u COMMAND TAB_GOTO file:/cgi-bin/restore_tab.cgi

Then place the following file inside ~/.w3m/cgi-bin and make it executable.

restore_tab.cgi

Opening magnet links

magnet.cgi can be used to make w3m auto open magnet links using Transmission.

Fingerprinting

Using tor

You can use torify(1) to route w3m traffic through tor.

$ torify w3m -v

User agent and headers

By default w3m uses its own user agent, meaning w3m users stand out amongst other users.

Fingerprint can be reduced by using a more generic user agent, language and http_accept header.

~/.w3m/config

user_agent Mozilla/5.0 (Windows NO 10.0; rev:91.0) Gecko/20100101 Firefox91.0
no_referer 1
cross_origin_referer 0
accept_language en-US,en;q=0.5
accept_encoding gzip, deflate
accept_media text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

Disable cookies

To disable cookies set use_cookie to 0 in ~/.w3m/config.

Disable cache

To disable cookies set no_cache to 1 in ~/.w3m/config.

Troubleshooting

Images flickering/causing lag

Unfortunately, sometimes w3m lags when trying to scroll past an image, to the point where the browser can become unresponsive for multiple seconds.

A solution to this is outright disabling images, but this breaks some websites (for example, hacker news relies on GIFs for comment indentation).

A more elegant solution would be to make a keybind to toggle images on or off, to do so add the following line to ~/.w3m/keymap:

keymap i COMMAND "SET_OPTION display_image=toggle ; RESHAPE"

w3m
