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.
-b          Show the bar at the bottom of the screen.
-w <width>  Set width of the bar.
-s <height> Set height of the bar.
-o <offset> Set bar's offset from the left. 0 disables.
-f      Force docking (use this if your WM isn't EWMH compliant)
-u <line>   Choose between underline (1) or overline (0).
-t <thickness> Thickness of underline. 0 to disable.
-n <font>   Font used. In the form of '-*-*-' etc.
-k <width> Set font fallback width.
-c <opacity> Requires a compositor. 0: Invisible, 1: Opaque.
-p	    Make the bar permanent.

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)
