NAME

lemonbar - Featherweight lemon-scented bar

SYNOPSIS

DESCRIPTION

lemonbar (formerly known as 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.

OPTIONS

-h: Display the help and exit.
-g widthxheight+x+y: Set the window geometry. If a parameter is omitted it's filled with the default value. If the y parameter is specified along with the -b switch then the position is relative to the bottom of the screen.
-b: Dock the bar at the bottom of the screen.
-d: Force docking without asking the window manager. This is needed if the window manager isn't EWMH compliant.
-f font: Define the font to load into one of the five slots (the number of slots is hardcoded and can be tweaked by changing the MAX_FONT_COUNT parameter in the source code).
-a number: Set number of clickable areas (default is 10)
-p: Make the bar permanent, don't exit after the standard input is closed.
-n name: Set the WM_NAME atom value for the bar.
-u pixel: Sets the underline width in pixels. The default is 1.
-B color: Set the background color of the bar. 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.
-F color: Set the foreground color of the bar. Accepts the same color formats as -B.
-R color: Set the border color of the bar. Accepts the same color formats as -B.
-r size: Add a border with the specified size. size must be a number in pixels.
-o offset: Add a vertical offset to the text. offset must be a number and can be negative. -o -3 will push the text 3 pixels up.

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 it's best to handle malformed input.

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.

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.

Abutton:command:

Create a clickable area starting from the current position, when the area is clicked command is executed. 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}

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.

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.

OUTPUT

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.
