.Sh DESCRIPTION
.Nm
is a minimalistic web browser that tries to stay out of the way so that
valuable screen real estate can be used for much more important stuff.
It has sane defaults and does not require one to learn a language to do any
configuration.
It was written by hackers for hackers
and it strives to be small, compact, and fast.
.Pp
.Nm
is very simple in its use.
Most actions are initiated via key or mouse bindings.
Key bindings are based on those of the
.Xr vi 1
text editor,
giving web browsing a similar feel to navigating a text document.
The
.Sx KEY BINDINGS
section below documents the various defaults and possible customizations.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl f Ar file
Specify an alternative configuration file.
.It Fl n
Open a new tab in a running
.Nm
for each specified URL.
This option requires
.Cm enable_socket
to be enabled.
.It Fl e Ar command
Execute arbitrary command (see the
.Sx COMMAND MODE
section below) in a running
.Nm
instance. This option requires
.Cm enable_socket
to be enabled. Example run: xxxterm -e "tabnew openbsd.org"; xxxterm -e
tabclose; xxxterm -e wq.
.It Fl S
Disable the toolbar.
.It Fl s Ar session_name
Open session that was saved with ":session save" command.
.It Fl T
Disable visualization of tabs.
.It Fl t
Disable tabs.
.It Fl V
Display version and exit.
.El
.Sh FAST STARTUP
The following notation is used throughout this page:
.Pp
.Bl -tag -width Ds -offset indent -compact
.It Cm C-
Control
.It Cm S-
Shift
.It Cm M1-
Meta 1 (sometimes marked Alt)
.It Cm M2-
Meta 2
.It Cm M3-
Meta 3
.It Cm M4-
Meta 4 (sometimes marked Windows)
.It Cm M5-
Meta 2
.It Cm MB1
Mouse button 1
.El
.Pp
To browse to a specific address,
either use the mouse to click on the address bar
or press
.Cm F6
to shift the keyboard focus to the address bar.
The address is then entered manually.
.Pp
The mouse can be used to navigate the page in the traditional manner,
or the keyboard can be used instead.
For example,
.Cm PageUp
and
.Cm PageDown
will scroll up and down the page.
.Pp
To follow a link,
either click on it or use the
.Cm f
key and have
.Nm
assign numbers to each link on the page;
entering that number on the keyboard will prompt
.Nm
to follow the link.
.Sh KEY BINDINGS
.Nm
provides many actions accessed via key or mouse bindings.
Most can be reprogrammed using a
.Cm keybinding
entry in the configuration file.
Each keyboard shortcut requires exactly one entry in the configuration file.
A shortcut can have multiple entries in the configuration file.
The format of the keybinding entry is as follows:
.Pp
.D1 keybinding = action,(!)keystroke(s)
.Pp
For example, "keybinding = tabnew,C-t" where
.Cm tabnew
is the action and
.Cm C-t
are
the keystrokes.
GTK has some default keybindings for manipulating text inside input
fields, such as the URI or search entry widget, for example
.Cm C-w
deletes a word. To override these defaults prefix your key with an
exclamation mark, like this: "keybinding = tabclose,!C-w".
The
.Cm clearall
key word is special and is meant to reset the key binding list to the GTK+
and WebKit defaults.
This keyword should be the first
.Cm keybinding
entry in the configuration file.
.Pp
Shift should be used sparingly since it gets in the way of non-USA keyboards.
See the accompanying configuration file for examples.
.Pp
The various bindings are documented below.
The relevant keybinding action is given afterwards, in parentheses.

provides buffer commands. Buffer commands are short, multi character
vi-like commands, often requiring an argument. Partial buffer commands
are
displayed in the buffer command statusbar element (see
.Cm statusbar_elems ) .
Pressing Esc or switching to another tab cancels a partially entered
buffer command. In the following list
.Cm arg
denotes the argument a buffer command accepts. Buffer commands are
defined as extended regular experssions.
Note that if a character is used as a shortcut it will not be interpreted
as the beginning of a buffer command. This is the case with
.Cm 0 .
.Pp
.Bl -tag -width "['][a-zA-Z0-9]XXX" -offset indent -compact
.It Cm gg
go to the top of the page
.It Cm gG
go to the bottom of the page
.It Cm [0-9]+%
go to the
.Cm arg

is missing, 1 is assumed. Going a
level up means going to a uri obtained from the current one by removing
the last slash ('/') character and everything that follows it
.It Cm gh
open the home page in the current tab
.It Cm m[a-zA-Z0-9]
set a mark denoted by
.Cm arg
at the current page position. These marks behave like those in vi or
less.

character (a letter or a digit), instead of a longer name. See the
.Cm M[a-zA-Z0-9] ,
.Cm go[a-zA-Z0-9]
and
.Cm gn[a-zA-Z0-9]
buffer commands for usage. Quickmarks are stored in
.Pa ~/.xxxterm/quickmarks
and are saved automatically after each
.Cm M[a-zA-Z0-9]
buffer command.
.Sh ABOUT SCREENS
The about screens are internally generated web pages by
.Nm
for user interaction.
These are entered in the address bar and the format is
.Cm about:screen
where screen is the desired screen to display.
For example about:favorites.
Any about screen can be used as the home page as specified by
.Cm home
in the configuration file.
.Pp
.Bl -tag -width "downloadsXXX" -offset indent -compact

.El
.Sh WHITELISTS
This section describes advanced usage settings.
Most users should use
.Cm browser_mode
instead to setup
.Nm
and skip over this section.
.Pp
.Nm
has a number of whitelists to control blocking cookies and Java Script
execution for FQDNs or domains.
When properly enabled these whitelists require either the FQDN or top level
domain to exist in the whitelists in order to allow cookies to be stored or
Java Script to execute.
Both Java Script and cookies have two whitelists associated with them.
The whitelists are called session and persistent.
Items in the session whitelists are only allowed for the lifetime of the
.Nm
instance.
Items in the persistent whitelists are stored on disk and are restored
upon restarting.
.Pp
Setting up the whitelists is a little tricky due to intricacies of WebKit.
In fact the semantics are different for cookies and Java Script.
.Pp
Cookie whitelist requires the following configuration to be set:
.Pp
.Bl -tag -width "enable_cookie_whitelistXXX" -offset indent -compact
.It Cm cookies_enabled
This is a WebKit setting and must be set to
.Pa 1
(ENABLED)
in order to be able to use a
cookie whitelist.
.It Cm enable_cookie_whitelist
This needs to be set to
.Pa 1
to enable the cookie whitelist functionality.
.It Cm cookie_wl
These entries in the configuration file are the actual domains names in the
cookie whitelist.
.El
.Pp
Java Script whitelist requires the following configuration to be set:
.Pp
.Bl -tag -width "enable_js_whitelistXXX" -offset indent -compact
.It Cm enable_scripts
This is a WebKit setting and must be set to
.Pa 0
(DISABLED)
in order to be able to use a
Java Script whitelist.
.It Cm enable_js_whitelist
This needs to be set to
.Pa 1
to enable the Java Script whitelist functionality.
.It Cm js_wl
These entries in the configuration file are the actual domains names in the
Java Script whitelist.
.El
.Pp
Plugin whitelist requires the following configuration to be set:
.Pp
.Bl -tag -width "enable_plugin_whitelistXXX" -offset indent -compact
.It Cm enable_plugins
This is a WebKit setting and must be set to
.Pa 1
(ENABLED)
in order to be able to use a
plugin whitelist.
.It Cm enable_plugin_whitelist
This needs to be set to
.Pa 1
to enable the plugin whitelist functionality.
.It Cm pl_wl
These entries in the configuration file are the actual domains names in the
plugin whitelist.
.El
.Pp
See the
.Pa FILES
section for additional configuration file entries and details
that alter runtime behavior.
.Sh FILES
.Bl -tag -width "/etc/xxxterm.confXXX" -compact
.It Pa ~/.xxxterm.conf
.Nm
user specific settings.
.It Pa ~/.xxxterm
.Nm
scratch directory.
.El
.Pp
.Nm
tries to open the user specific file,
.Pa ~/.xxxterm.conf .
If that file is unavailable,
it then uses built-in defaults.
.Pp
The format of the file is \*(Ltkeyword\*(Gt = \*(Ltsetting\*(Gt.
For example:
.Pp
.Dl http_proxy = http://127.0.0.1:8080
.Pp
Enabling or disabling an option is done by using 1 or 0 respectively.
.Pp
The file supports the following keywords:
.Pp
.Bl -tag -width "enable_cookie_whitelistXXX" -offset indent -compact
.It Cm alias
Defines an alias for a given URL, so that the URL is loaded when the alias is
entered in the address bar.
If the aliased URL includes a %s format specifier, then any argument given after
the alias on the address bar is substituted.
For example, if g,http://www.google.com/search?q=%s is defined as an alias,
then the URL http://www.google.com/search?q=foo is loaded when navigating to
"g foo".
.It Cm allow_volatile_cookies
If set cookies are stored in the session cache but will be discarded once
.Nm
exits.
Unfortunately enabling this does allow for some limited tracking on the web.
.It Cm append_next
When set a new tab is appended after the current tab instead of being appended
as the last tab.
.It Cm browser_mode
The
.Nm
browser has 3 default operating modes:
.Pa normal
(the default),
.Pa whitelist
and
.Pa kiosk .
In the
.Pa normal
mode the browser allows all cookies, plugins and Java Script as any other
browser would.
This means that all cookies are saved to persistent storage and that all
Java Script and plugins run.
.Pp
On the other hand, using the
.Pa whitelist
mode enables whitelists.
This requires the user to add all the required
.Pa cookie_wl ,
.Pa js_wl
and
.Pa pl_wl
items.
If a domain does not appear in the whitelists
.Nm
disallows cookies, Java Script and plugin execution.
.Pp
In
.Pa kiosk
mode the browse works just like
.Pa normal
mode however the toolbar only has the backward, forward and home button.
.Pp
This setting must be the first entry in
.Pa ~/.xxxterm.conf
because it sets advanced settings that can be overridden later in the file.
See the default config file for more details.
.It Cm cmd_font
Set the command prompt font.
E.g.
.Pa cmd_font = monospace normal 9 .
.It Cm cookie_policy
This field delineates the cookie policy.
Possible values are: no3rdparty, reject 3rd party cookies.
accept, accept all cookies.
reject, reject all cookies.
.It Cm cookie_wl
This is a cookie whitelist item.
Use multiple times to add multiple entries.
Valid entries are for example *.moo.com and the equivalent .moo.com.
A fully qualified host is also valid and is for example www.moo.com.
.It Cm cookies_enabled
Enable cookies.
.It Cm ctrl_click_focus
Give focus in newly created tab instead of opening it in the background.
.It Cm default_script
Path to the script used as the default value for the run_script
command.
.It Cm default_zoom_level
Set the default browsing zoom level.
.It Cm download_dir
Locations where files are downloaded to.
This directory must exist and
.Nm
validates that during startup.
.It Cm enable_cookie_whitelist
When enabled all cookies must be in the whitelist or they are rejected.
Additionally whitelisted cookies also enable HTML5 local storage for the
domain.
.It Cm enable_js_whitelist
When enabled all domains must be in the js whitelist in order to run Java
Script.
NOTE: Make sure
.Cm enable_scripts
is set to 0.
.It Cm enable_plugin_whitelist

the command widget, is term you want to search for using search_string

If the string does not contain a dot nor a slash, is not a
path to a local file and does not resolves to an IP then it is assumed

It has been reported that tsocks works with
.Nm .

For example, to download and view a pdf using kpdf set
.Pa mime_type = application/pdf,kpdf .
To set a default value use *, for example,
.Pa mime_type = video/*,mplayer .
Note that the action is only passed the URL and not all applications are
capable of dealing with a URL and therefore one might have to create a wrapper
script to download the content first.  Alternatively one can add the
.Pa @
in front of the MIME type to indicate "download first".
For example,
.Pa mime_type = @application/pdf,xpdf .
When
.Pa @
is use the file will be downloaded to the
.Pa download_dir
before the MIME handler is called.

is not set then the URL bar will color all HTTPS connections red.
.Pp
WebKit only supports a single PEM file.
Many OS' or distributions have many PEM files.
One can simply concatenate all separate files into one large one.
E.g.
.Cm for i in `ls`; do cat $i >> cert.pem; done
and use the resulting cert.pem file as the input to
.Cm ssl_ca_file .
It is advisable to periodically recreate the cert.pem file.

This value is only used if
.Cm ssl_ca_file
is set.
.It Cm statusbar_elems

.Sh BUGS
When
.Cm save_global_history
is enabled
.Nm
is supposed to, in addition to restoring the global history, color the
visited links accordingly; however due to bug #51747 in WebKit this does
not happen.
