=head1 SYNOPSIS
I<bar> [-h | -g I<width>B<x>I<height>B<+>I<x>B<+>I<y> | -b | -d | -f I<font> | -p | -u I<pixel> | -B I<color> | -F I<color>]
=head1 DESCRIPTION
B<bar> is a lightweight bar entirely based on XCB. Provides full UTF-8 support, basic formatting, RandR and Xinerama support and EWMH compliance without wasting your precious memory.
=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<-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>
Comma separated list of fonts, bar supports a maximum of five fonts (the limit can be tweaked by changing the MAX_FONT_COUNT parameter in the source).
=item B<-p>
Make bar permanent, don't exit after the standard input is closed.
=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> might be either in hex format (#aarrggbb) or in the symbolic name format (eg. white, indianred, darkgray). 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>.
=back
=head1 FORMATTING
bar provides a screenrc-inspired formatting syntax to allow full customization at runtime. Every formatting block is opened with B<%{> and closed by B<}> and accepts the following commands, the parser tries it's best to handle malformed input.
=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<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> is a 1-based index of the font list supplied to bar. Any other value (for example I<->) resets bar to normal behaviour (matching the first font that can be used for that character). If the selected font can't be used to draw a character, bar will fall back to normal behaviour 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 executed. 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 bar is rendering 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.
=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 bar 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.
