B<lemonbar> (formerly known as 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> 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.
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<%>).
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> 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
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 printed on stdout. 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 up and scroll down movements. Your mileage may vary.
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.
