.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBlemonbar\fR (formerly known as \fBbar\fR) is a lightweight bar entirely based on \s-1XCB.\s0 Provides full \s-1UTF\-8\s0 support, basic formatting, RandR and Xinerama support and \s-1EWMH\s0 compliance without wasting your precious memory.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-h\fR" 4
.IX Item "-h"
Display the help and exit.
.IP "\fB\-g\fR \fIwidth\fR\fBx\fR\fIheight\fR\fB+\fR\fIx\fR\fB+\fR\fIy\fR" 4
.IX Item "-g widthxheight+x+y"
Set the window geometry. If a parameter is omitted it's filled with the default value. If the \fIy\fR parameter is specified along with the \fB\-b\fR switch then the position is relative to the bottom of the screen.
.IP "\fB\-b\fR" 4
.IX Item "-b"
Dock the bar at the bottom of the screen.
.IP "\fB\-d\fR" 4
.IX Item "-d"
Force docking without asking the window manager. This is needed if the window manager isn't \s-1EWMH\s0 compliant.
.IP "\fB\-f\fR \fIfont\fR" 4
.IX Item "-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 \s-1MAX_FONT_COUNT\s0 parameter in the source code).
.IP "\fB\-a\fR \fInumber\fR" 4
.IX Item "-a number"
Set number of clickable areas (default is 10)
.IP "\fB\-p\fR" 4
.IX Item "-p"
Make the bar permanent, don't exit after the standard input is closed.
.IP "\fB\-n\fR \fIname\fR" 4
.IX Item "-n name"
Set the \s-1WM_NAME\s0 atom value for the bar.
.IP "\fB\-u\fR \fIpixel\fR" 4
.IX Item "-u pixel"
Sets the underline width in pixels. The default is 1.
.IP "\fB\-B\fR \fIcolor\fR" 4
.IX Item "-B color"
Set the background color of the bar. \fIcolor\fR 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.
.IP "\fB\-F\fR \fIcolor\fR" 4
.IX Item "-F color"
Set the foreground color of the bar. Accepts the same color formats as \fB\-B\fR.
.IP "\fB\-U\fR \fIcolor\fR" 4
.IX Item "-U color"
Set the underline color of the bar. Accepts the same color formats as \fB\-B\fR.
.SH "FORMATTING"
.IX Header "FORMATTING"
lemonbar provides a screenrc-inspired formatting syntax to allow full customization at runtime. Every formatting block is opened with \f(CW\*(C`%{\*(C'\fR and closed by \f(CW\*(C`}\*(C'\fR and accepts the following commands, the parser tries its best to handle malformed input. Use \f(CW\*(C`%%\*(C'\fR to get a literal percent sign (\f(CW\*(C`%\*(C'\fR).
.IP "\fBR\fR" 4
.IX Item "R"
Swap the current background and foreground colors.
.IP "\fBl\fR" 4
.IX Item "l"
Aligns the following text to the left side of the screen.
.IP "\fBc\fR" 4
.IX Item "c"
Aligns the following text to the center of the screen.
.IP "\fBr\fR" 4
.IX Item "r"
Aligns the following text to the right side of the screen.
.IP "\fBO\fR\fIwidth\fR" 4
.IX Item "Owidth"
Offset the current position by \fIwidth\fR pixels in the alignment direction.
.IP "\fBB\fR\fIcolor\fR" 4
.IX Item "Bcolor"
Set the text background color. The parameter \fIcolor\fR can be \fI\-\fR or a color in one of the formats mentioned before. The special value \fI\-\fR resets the color to the default one.
.IP "\fBF\fR\fIcolor\fR" 4
.IX Item "Fcolor"
Set the text foreground color. The parameter \fIcolor\fR can be \fI\-\fR or a color in one of the formats mentioned before. The special value \fI\-\fR resets the color to the default one.
.IP "\fBT\fR\fIindex\fR" 4
.IX Item "Tindex"
Set the font used to draw the following text. The parameter \fIindex\fR can either be \fI\-\fR or the 1\-based index of the slot which contains the desired font. If the parameter is \fI\-\fR 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
.IP "\fBU\fR\fIcolor\fR" 4
.IX Item "Ucolor"
Set the text underline color. The parameter \fIcolor\fR can be \fI\-\fR or a color in one of the formats mentioned before. The special value \fI\-\fR resets the color to the default one.
.IP "\fBA\fR\fIbutton\fR:\fIcommand\fR:" 4
.IX Item "Abutton:command:"
Create a clickable area starting from the current position, when the area is clicked \fIcommand\fR is printed on stdout. The area is closed when a \fBA\fR token, not followed by : is encountered.
.Sp
Eg. \fI%{A:reboot:} Click here to reboot %{A}\fR
.Sp
The \fIbutton\fR 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.
.Sp
Nested clickable areas can trigger different commands.
.Sp
Eg. \fI%{A:reboot:}%{A3:halt:} Left click to reboot, right click to shutdown %{A}%{A}\fR
.IP "\fBS\fR\fIdir\fR" 4
.IX Item "Sdir"
Change the monitor the bar is rendered to. \fIdir\fR can be either
.RS 4

.IX Item "+/-"
Next/previous monitor.
.IP "\fBf\fR/\fBl\fR" 4

.IX Item "u"
Draw a line under the text.
.SH "OUTPUT"
.IX Header "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.
