=head1 NAME
lemonbar - Featherweight lemon-scented bar
=for HTML <img src="https://github.com/LemonBoy/bar/workflows/Does%20this%20build%20look%20infected%3F/badge.svg">
=head1 SYNOPSIS
I<lemonbar> [-h | -g I<width>B<x>I<height>B<+>I<x>B<+>I<y> | -o | -b | -d | -f I<font> | -p | -n I<name> | -u I<pixel> | -B I<color> | -F I<color> | -U I<color>]
=head1 DESCRIPTION
B<lemonbar> (formerly known as B<bar>) is a lightweight statusbar based on XCB.
Provides full UTF-8 support, basic formatting, RandR and Xinerama support and
EWMH compliance without wasting your precious memory.
=head1 INPUT
The data to be parsed is read from the standard input, parsing and printing the
input data are delayed until a newline is found.
=head1 OPTIONS
=over
=item B<-h>
Display the help and exit.
=item B<-g> I<width>B<x>I<height>B<+>I<x>B<+>I<y>
Set the window geometry. If a parameter is omitted it's filled with the default value. If the I<y> parameter is specified along with the B<-b> switch then the position is relative to the bottom of the screen.
=item B<-o> I<name>
Set next output to I<name>. May be used multiple times; order is significant. If any B<-o> options are given, only B<-o> specified monitors will be used. Invalid output names are silently ignored. (only supported on randr configurations at this time)
=item B<-b>
Dock the bar at the bottom of the screen.
=item B<-d>
Force docking without asking the window manager. This is needed if the window manager isn't EWMH compliant.
=item B<-f> I<font>
Specifies a font to use. Can be used multiple times to load more than a single
font.
=item B<-p>
Make the bar permanent, don't exit after the standard input is closed.
=item B<-n> I<name>
Set the WM_NAME atom value for the bar.
=item B<-u> I<pixel>
Sets the underline width in pixels. The default is 1.
=item B<-B> I<color>
Set the background color of the bar. I<color> must be specified in the hex format (#aarrggbb, #rrggbb, #rgb). If no compositor such as compton or xcompmgr is running the alpha channel is silently ignored.
=item B<-F> I<color>
Set the foreground color of the bar. Accepts the same color formats as B<-B>.
=item B<-U> I<color>
Set the underline color of the bar. Accepts the same color formats as B<-B>.
=back
=head1 FORMATTING
lemonbar provides a screenrc-inspired formatting syntax to allow full customization at runtime. Every formatting block is opened with C<%{> and closed by C<}> and accepts the following commands, the parser tries its best to handle malformed input. Use C<%%> to get a literal percent sign (C<%>).
=over
=item B<R>
Swap the current background and foreground colors.
=item B<l>
Aligns the following text to the left side of the screen.
=item B<c>
Aligns the following text to the center of the screen.
=item B<r>
Aligns the following text to the right side of the screen.
=item B<O>I<width>
Offset the current position by I<width> pixels in the alignment direction.
=item B<B>I<color>
Set the text background color. The parameter I<color> can be I<-> or a color in one of the formats mentioned before. The special value I<-> resets the color to the default one.
=item B<F>I<color>
Set the text foreground color. The parameter I<color> can be I<-> or a color in one of the formats mentioned before. The special value I<-> resets the color to the default one.
=item B<T>I<index>
Set the font used to draw the following text. The parameter I<index> can either be I<-> or the 1-based index of the slot which contains the desired font. If the parameter is I<-> lemonbar resets to the normal behavior (matching the first font that can be used for the character). If the selected font can't be used to draw a character, lemonbar will fall back to normal behavior for that character
=item B<U>I<color>
Set the text underline color. The parameter I<color> can be I<-> or a color in one of the formats mentioned before. The special value I<-> resets the color to the default one.
=item B<A>I<button>:I<command>:
Create a clickable area starting from the current position, when the area is clicked I<command> is printed on stdout. The area is closed when a B<A> token, not followed by : is encountered.
Eg. I<%{A:reboot:} Click here to reboot %{A}>
The I<button> field is optional, it defaults to the left button, and it's a number ranging from 1 to 5 which maps to the left, middle, right, scroll up and scroll down movements. Your mileage may vary.
Nested clickable areas can trigger different commands.
Eg. I<%{A:reboot:}%{A3:halt:} Left click to reboot, right click to shutdown %{A}%{A}>
=item B<S>I<dir>
Change the monitor the bar is rendered to. I<dir> can be either
=over
=item B<+>/B<->
Next/previous monitor.
=item B<f>/B<l>
First/last monitor.
=item I<0-9>
Nth monitor.
=item I<n>B<NAME>
Named monitor.
Eg. I<%{SnHDMI-0} This text will show up on the HDMI-0 output>
=back
=back
B<Attribute modifiers>
=over
=item B<+>I<attribute>
Set the attribute I<attribute> for the following text.
=item B<->I<attribute>
Unset the attribute I<attribute> for the following text.
=item B<!>I<attribute>
Toggle the attribute I<attribute> for the following text.
=back
Where I<attribute> is one of the following
=over
=item B<o>
Draw a line over the text.
=item B<u>
Draw a line under the text.
=back
=head1 OUTPUT
Clicking on an area makes lemonbar output the command to stdout, followed by a newline, allowing the user to pipe it into a script, execute it or simply ignore it. Simple and powerful, that's it.
