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.
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.
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.
Set the foreground color of the bar. Accepts the same color formats as B<-B>.

=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.
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.
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.
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.
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 down and scroll up movements. Your mileage may vary.
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.
