b(ar) a(in't) r(ecursive)
=========================
2012-2013 (C) The Lemon Man
A lightweight bar based on XCB (yay). Provides foreground/background color
switching along with text alignment (screw you dzen!), full utf8 support
and reduced memory footprint. It also supports transparency when using a
compositor such as compton. Nothing less and nothing more.
Xinerama support
----------------
Thanks to @Stebalien now bar is Xinerama compliant, just compile it with
XINERAMA=1 and you're good to go!
Options
-------
bar accepts a couple of command line switches.
```
-h Show the help and bail out.
-p Make the bar permanent.
-f Force docking (use this if your WM isn't EWMH compliant)
-b Show the bar at the bottom of the screen.
```
Configuration
-------------
Change the config.h file and you're good to go!
The text background and foreground are respectively the first and the second
entries in the palette (COLOR0 and COLOR1).
Colors
------
Attached there's palette.pl, an handy tool that extracts a palette from your
X colors and returns it ready to be pasted in the configuration file.
```
palette.pl <.Xresources / .Xdefaults path>
```
If you keep your colors in a separate file just feed that file and you're good
to go.
Text formatting
---------------
All the format commands are preceded by a backslash (\\).
To draw a backslash just backslash escape it (\\\\).
```
f<0-9> Selects the text foreground color from the palette.
b<0-9> Selects the text background color from the palette.
u<0-9> Selects the underline color from the palette.
To reset the bg/fg/underline color just pass 'r' as the color index.
l Aligns the text to the left.
c Aligns the text to the center.
r Aligns the text to the right.
```
The options below are valid only if compiled with Xinerama support.
```
s<0-9> Switches to screen 0-9
sn Switches to next screen
sp Switches to previous screen
sr Switches to the rightmost screen (the latest)
sl Switches to the leftmost screen (the first)
```

=head1 NAME
bar - bar ain't recursive
=head1 SYNOPSIS
I<bar> [-h | -g I<width>B<x>I<height> | -b | -d | -f I<font> | -a I<alpha>| -p | -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>
Set the window geometry. Both the parameters can be omitted, bar defaults the former to the whole width and the height to the font height + 1 pixel.
=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 two fonts.
=item B<-a> I<alpha>
Set the bar alpha in range 0.0 to 1.0. This requires a compositor manager such as Compton.
=item B<-p>
Make bar permanent, don't exit after the standard input is closed.
=item B<-B> I<color>
Set the background color of the bar. I<color> might be either in hex format (#rrggbb) or in the symbolic name format (eg. white, brightred, darkgray).
=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<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<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.
