Formatting

lemonbar provides a screenrc-inspired formatting syntax to allow full customization at runtime. Every formatting block is opened with %{ and closed by } and accepts the following commands, the parser tries its best to handle malformed input. Use %% to get a literal percent sign (%).

• R: Swap the current background and foreground colors.
• l: Aligns the following text to the left side of the screen.
• c: Aligns the following text to the center of the screen.
• r: Aligns the following text to the right side of the screen.
• Owidth: Offset the current position by width pixels in the alignment direction.
• Bcolor: Set the text background color. The parameter color can be - or a color in one of the formats mentioned before. The special value - resets the color to the default one.
• FColor: Set the text foreground color. The parameter color can be - or a color in one of the formats mentioned before. The special value - resets the color to the default one.
• Tindex: Set the font used to draw the following text. The parameter index can either be - or the 1-based index of the slot which contains the desired font. If the parameter is - 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
• Ucolor: Set the text underline color. The parameter color can be - or a color in one of the formats mentioned before. The special value - resets the color to the default one.
• Sdir: Change the monitor the bar is rendered to. dir can be either
• +/-: Next/previous monitor.
• f/l: First/last monitor.
• 0-9: Nth monitor.
• nNAME: Named monitor. Eg. %{SnHDMI-0} This text will show up on the HDMI-0 output

Attribute modifiers

• +attribute: Set the attribute attribute for the following text.
• -attribute: Unset the attribute attribute for the following text.
• !attribute: Toggle the attribute attribute for the following text.

Where attribute is one of the following

• o: Draw a line over the text.
• u: Draw a line under the text.

Clickable buttons

• Abutton:command:

Create a clickable area starting from the current position, when the area is clicked command is printed on stdout. The area is closed when a A token, not followed by : is encountered.

Eg. %{A:reboot:} Click here to reboot %{A}

The 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. %{A:reboot:}%{A3:halt:} Left click to reboot, right click to shutdown %{A}%{A}
