.SH NAME
neovimb - Vim Browser - A modal web browser based on WebKit, inspired by vimb.
.
.
.SH SYNOPSIS
.B neovimb
.OP OPTIONS
.RI [ URI "|" file "|" - ]
.
.
.SH DESCRIPTION
neovimb is a WebKit based web browser that behaves like the Vimperator
plugin for Firefox and has usage paradigms from the great editor, Vim.
The goal of neovimb is to build a completely keyboard-driven, efficient
and pleasurable browsing-experience.
.
.
.SH OPTIONS
If no \fIURI\fP or \fIfile\fP is given, neovimb will open the configured
home-page.
If \fIURI\fP is '-', neovimb reads the HTML to display from stdin.
.P
Mandatory arguments to long options are mandatory for short options too.
.TP
.BI "\-C, \-\-cmd " "CMD"
Run \fICMD\fP as ex command line right before the first page is loaded.
If the flag is used more than one time, the commands are called in order they
are given.
You could also pass several ex commands in one \fICMD\fP,
if they are separated by "|".
.sp
.EX
neovimb --cmd "set dark-mode=on|set header=Referer,DNT=1"
.EE
.TP
.BI "\-c, \-\-config " "FILE"
Use custom configuration given as \fIFILE\fP.
This will also be applied on new spawned instances.
.TP
.BI "\-e, \-\-embed " "WINID"
.I WINID
of an XEmbed-aware application, that neovimb will use as its parent.
.TP
.B "\-h, \-\-help"
Show help options.
.TP
.BI "\-p, \-\-profile " "PROFILE-NAME"
Create or open specified configuration profile.
Configuration data for the profile is stored in a directory named
\fIPROFILE-NAME\fP under default directory for configuration data.
.TP
.B "\-v, \-\-version"
Print build and version information and then quit.
.TP
.B "\-\-no-maximize"
Do no attempt to maximize window.
.TP
.B "\-\-bug-info"
Prints information about used libraries for bug reports and then quit.
.
.
.SH MODES
neovimb is modal and has the following main modes:
.IP "Normal Mode"
The default mode.
Pressing Escape always enter normal mode.
.IP "Input Mode"
Used for editing text elements in a webpage.
.IP "Command Mode"
Execute `ex` commands from the builtin inputbox (commandline).
.IP "Pass-Through Mode"
In Pass-Through mode only the `<Esc>` and `<C-[>` keybindings are interpreted
by neovimb, all other keystrokes are given to the webview to handle them.
This allows the use of a website's configured keybindings, that might otherwise
be swallowed by neovimb.
.
.
.SH NORMAL MODE COMMANDS
Some of the Normal Model Commands can have a numeric count to multiply the
effect of the command.
If a command supports the count this is shown as [\fBN\fP].

.SS Hinting
Hinting in neovimb is how you accomplish the tasks that you would do with the
mouse in common mouse-driven browsers: open a URI, yank a URI, save a page and
so on. When hinting is started, the relevant elements on the page will
be marked by labels generated from configured `hint-keys'.
Hints can be selected by using <Tab>, <C-I> or <C-Tab>, <C-O>,
by typing the chars of the label, or filtering the elements by some text
that is part of the hinted element (like URI, link text, button label)
or any combination of these methods.
If <enter> is pressed, the current active hint will be fired.
If only one possible hint remains, this will be fired automatically.
.P
.BR Syntax: " ;{mode}{hint}"
.P
Start Hints mode.
Different elements depending on \fImode\fP are highlighted and `numbered'.
Elements can be selected either by typing their label, or by typing part
of their text (\fIhint\fP) to narrow down the result.
When an element has been selected, it is automatically clicked
or used (depending on \fImode\fP) and hint mode ends.
.P
The filtering of hints by text splits the query at ' ' and use the single parts
as separate queries to filter the hints.
This is useful for hints that have a lot of filterable chars in common
and many chars are required to make a distinct selection.
For example ';over tw' will easily select the second hint out of
{'very long link text one', 'very long link text two'}.
.P
The following keys have special meanings in Hints modes:
.PD 0
.TP
.B <CR>
Selects the first highlighted element, or the current focused.
.TP
.B <Tab>
Moves the focus to the next hint element.
.TP
.B <S-Tab>
Moves the focus to the previous hint element.
.TP
.B <Esc>, CTRL\-C, CTRL\-[
Exits Hints mode without selecting an element.

This is only available if neovimb was compiled with the QUEUE feature.
.TP
.B ;P
Push the hint's URI to the beginning of the Read It Later queue like the
`:qunshift' command.
This is only available if neovimb was compiled with the QUEUE feature.
.TP

.PD
.RE
.TP
.BR Syntax: " g;{mode}{hint}"
Start an extended hints mode and stay there until <Esc> is pressed.
Like normal hinting, except that after a hint is selected, hints
remain visible so that another one can be selected with the same action
as the first.

.SH COMMAND MODE
Commands that are listed below are ex-commands like in Vim, that are typed
into the inputbox (the command line of neovimb).
The commands may vary in their syntax or in the parts they allow,
but in general they follow a simple syntax.
.P
.BR Syntax: " :[:| ][N]cmd[name][!][ lhs][ rhs]"
.sp
Where \fIlhs\fP (left hand side) must not contain any unescaped space.
The syntax of the rhs (right hand side) if this is available depends on the
command.
At the moment the count parts [N] of commands is parsed, but currently there is
no command that uses the count.
.sp
To avoid this, the commands can be prefixed by one or more additional `:' or
whitespace.
.P
Multiple commands, separated by a `|' can be given in a single command line
and will be executed consecutively.
The pipe can be included as an argument to a command by escaping it with a
backslash.
.br
Following commands process the entire command-line string literally.
These commands will include any `|' as part of their argument string and so
can not be followed by another command.

.BI ":t[abopen] [" URI ]
Open the give \fIURI\fP in a new window.
If \fIURI\fP is empty, the configured 'home-page' is opened.
.
.SS Key Mapping
Key mappings allow users to alter the actions of key presses.
Each key mapping is associated with a mode and only has effect
when the mode is active.
The following commands allow the user to substitute one sequence
of key presses by another.
.P
.BR Syntax: " :{m}map {lhs} {rhs}"
.P
Note that the \fIlhs\fP ends with the first found space.
If you want to use space also in the {lhs} you have to escape this
with a single `\\', as shown in the examples.
.sp
The \fIrhs\fP starts with the first non-space char. If you want a \fIrhs\fP
that starts with a space, you have to use "<Space>".
.P
Standard key mapping commands are provided for these modes \fIm\fP:
.PD 0
.TP
.B n
Normal mode: when browsing normally.
.TP
.B i
Insert mode: when interacting with text fields on a website.
.TP
.B c
Command Line mode: when typing into neovimb's command line.
.PD
.P
Most keys in key sequences are represented simply by the character that you
see on the screen when you type them.
However, as a number of these characters have special meanings, and a
number of keys have no visual representation, a special notation is required.
.P
As special key names have the format \fI<...>\fP.
The following special keys can be used: <Left>, <Up>, <Right>, <Down>
for the cursor keys, <Tab>, <Esc>, <CR>, <Space>, <BS>, <F1>-<F12> and <C-A>-<C-Z>.
.TP
.PD 0

.TP
.BI ":im[ap] {" lhs "} {" rhs }
.TP
.BI ":cm[ap] {" lhs "} {" rhs }
Map the key sequence \fIlhs\fP to \fIrhs\fP for the modes where the map
command applies.
The result, including \fIrhs\fP, is then further scanned for mappings.
This allows for nested and recursive use of mappings.
.RS
.sp
.IP ":cmap <C-G>h /home/user/downloads/"
Adds a keybind to insert a file path into the input box.
This could be useful for the `:save' command
that could be used as ":save ^Gh".
.IP ":nmap <F1> :set scripts=on<CR>:open !glib<Tab><CR>"
This will enable scripts and lookup the first bookmarked URI with the tag
`glib' and open it immediately if F1 key is pressed.
.IP ":nmap \e \e  50G"
Example which maps two spaces to go to 50% of the page.
.RE

.SS Handlers
Handlers allow specifying external scripts to handle alternative URI methods.
.TP
.BI ":handler-add " "handler" "=" "cmd"
Adds a handler to direct \fIhandler\fP links to the external \fIcmd\fP.
The \fIcmd\fP can contain one placeholder `%s` that will be filled by the
full URI given when the command is called.
.RS
.P
.PD 0

to handle ftp downloads via wget.
.PD
.RE
.TP
.BI ":handler-remove " "handler"
Remove the handler for the given URI \fIhandler\fP.
.
.SS Shortcuts
Shortcuts allow the opening of an URI built up from a named template with additional
parameters.
If a shortcut named 'dd' is defined, you can use it with `:open dd
list of parameters' to open the generated URI.
.P
Shortcuts are convenient to use with search engines where the URI is standardised
and a single parameter is user defined.
.TP
.BI ":shortcut-add " shortcut = URI
Adds a shortcut with the \fIshortcut\fP and \fIURI\fP template.
The \fIURI\fP can contain multiple placeholders $0-$9 that will be
filled by the parameters given when the shortcut is called.
The parameters given when the shortcut is called will be split
into as many parameters like the highest used placeholder.
.sp
To use spaces within the parameters, the parameters can be grouped by
surrounding them with single-or double quotes-as shown in example shortcut
`map'.
.RS
.P
.PD 0
.IP ":shortcut-add dl=https://duckduckgo.com/lite/?q=$0"

.RE
.TP
.BI ":shortcut-remove " shortcut
Remove the search engine to the given \fIshortcut\fP.
.TP
.BI ":shortcut-default " shortcut
Set the shortcut for given \fIshortcut\fP as the default, that is the shortcut
to be used if no shortcut is given and the string to open is not an URI. It
doesn't matter if the \fIshortcut\fP is already in use or not to be able to set
it.
.
.SS Settings
.TP
.BI ":se[t] " var = value
Set configuration values named by \fIvar\fP.
To set boolean variable you should use 'on', 'off' or 'true' and 'false'.
Colors are given as hexadecimal value like '#f57700'. Spaces or more equals
signs in \fIvalue\fP just work without quotes: for example,
":set sans-serif-font=Some Sans Font".
.TP
.BI ":se[t] " var += value
Add the \fIvalue\fP to a number option, or append the \fIvalue\fP to a string
option.

.SS Automatic commands
An autocommand is a command that is executed automatically in response to some
event, such as a URI being opened.
Autocommands are very powerful.
Use them with care and they will help you avoid typing many commands.
.P
Autocommands are built with following properties.
.TP
.I group
When the [\fIgroup\fP] argument is not given, neovimb uses the current group as
defined with ':augroup', otherwise, neovimb uses the group defined with
[\fIgroup\fP].
Groups are useful to remove multiple grouped autocommands.
.TP
.I event
You can specify a comma separated list of event names.
No white space can be used in this list.

No data has been sent or received yet, the load may still fail for transport issues.
.TP
.B LoadStarted
Fired if a new page is going to be opened.
No data has been received yet, the load may still fail for transport issues.
.TP
.B LoadCommitted
Fired if first data chunk has arrived, meaning that the necessary transport
requirements are established, and the load is being performed.
This is the right event to toggle content related setting
like 'scripts', 'plugins' and such things.
.TP
.B LoadFinished
Fires when everything that was required to display on the page has been loaded.
.TP
.B DownloadStarted
Fired right after a download is started.
.TP

Patterns:
.IP "\fB*\fP"
Matches any sequence of characters.
This includes also '/' in contrast to shell patterns.
.IP "\fB?\fP"
Matches any single character except of '/'.
.IP "\fB{one,two}\fP"
Matches 'one' or 'two'.
Any '{', ',' and '}' within this pattern must be escaped by a '\\'.
\&'*' and '?' have no special meaning within the curly braces.
.IP "\fB\e\fP"
Use backslash to escape the special meaning of '?*{},' in the pattern or
pattern list.
.PD
.RE
.TP
.I cmd
Any `ex` command neovimb understands.
The leading ':' is not required.
Multiple commands can be separated by '|'.
.TP
.BI ":au[tocmd] [" group "] {" event "} {" pat "} {" cmd "}"
Add \fIcmd\fP to the list of commands that neovimb will execute automatically on
\fIevent\fP for a URI matching \fIpat\fP autocmd-patterns.
neovimb always adds the \fIcmd\fP after existing autocommands, so that the
autocommands are executed in the order in which they were given.
.TP
.BI ":au[tocmd]! [" group "] {" event "} {" pat "} {" cmd "}"
Remove all autocommands associated with \fIevent\fP and which pattern match
\fIpat\fP, and add the command \fIcmd\fP.
Note that the pattern is not matches literally to find autocommands
to remove, like Vim does.

If there is no '=' after the header name, then the complete header
will be removed from the request, if the '=' is present means that
the header value is set to empty value.

Note that webkit reused already set headers in case of a reload of a page.
So if there are headers removed that where previously use to access a certain
page and the page is reloaded or opened via back/forward history the header
will still be sent.
