=head1 NAME lemonbar - Featherweight lemon-scented bar =for HTML <a href="https://travis-ci.org/LemonBoy/bar"><img src="https://travis-ci.org/LemonBoy/bar.svg?branch=master"></a> =head1 SYNOPSIS I<lemonbar> [-h | -g I<width>B<x>I<height>B<+>I<x>B<+>I<y> | -b | -d | -f I<font> | -p | -n I<name> | -u I<pixel> | -B I<color> | -F I<color> | -r I<size> | -o I<offset> | -l I<path> | -s | -S ] =head1 DESCRIPTION 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. =head1 OPTIONS =over =item B<-h> Display the help and exit. =item B<-g> I<width>B<x>I<height>B<+>I<x>B<+>I<y> 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. =item B<-b> Dock the bar at the bottom of the screen. =item B<-d> Force docking without asking the window manager. This is needed if the window manager isn't EWMH compliant. =item B<-f> I<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). =item B<-a> I<number> Set number of clickable areas (default is 10) =item B<-p> Make the bar permanent, don't exit after the standard input is closed. =item B<-n> I<name> Set the WM_NAME atom value for the bar. =item B<-u> I<pixel> Sets the underline width in pixels. The default is 1. =item B<-B> I<color> 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. =item B<-F> I<color> Set the foreground color of the bar. Accepts the same color formats as B<-B>. =item B<-R> I<color> Set the border color of the bar. Accepts the same color formats as B<-B>. =item B<-r> I<size> Add a border with the specified size. I<size> must be a number in pixels. =item B<-s> Rotate text 90deg to the right =item B<-S> Rotate text 90deg to the left =item B<-o> I<offset> Add a vertical offset to the text. I<offset> must be a number and can be negative. I<-o -3> will push the text 3 pixels up. =item B<-l> I<path> Set the path of the file to read text from =back =head1 FORMATTING lemonbar provides a screenrc-inspired formatting syntax to allow full customization at runtime. Every formatting block is opened with B<%{> and closed by B<}> and accepts the following commands, the parser tries it's best to handle malformed input. =over =item B<R> Swap the current background and foreground colors. =item B<l> Aligns the following text to the left side of the screen. =item B<c> Aligns the following text to the center of the screen. =item B<r> Aligns the following text to the right side of the screen. =item B<B>I<color> 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. =item B<T>I<index> 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 =item B<U>I<color> 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. =item B<A>I<button>:I<command>: Create a clickable area starting from the current position, when the area is clicked I<command> is executed. The area is closed when a B<A> token, not followed by : is encountered. Eg. I<%{A:reboot:} Click here to reboot %{A}> 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. Nested clickable areas can trigger different commands. Eg. I<%{A:reboot:}%{A3:halt:} Left click to reboot, right click to shutdown %{A}%{A}> =item B<S>I<dir> Change the monitor the bar is rendered to. I<dir> can be either =over =item B<+>/B<-> Next/previous monitor. =item B<f>/B<l> First/last monitor. =item I<0-9> Nth monitor. =back =back B<Attribute modifiers> =over =item B<+>I<attribute> Set the attribute I<attribute> for the following text. =item B<->I<attribute> Unset the attribute I<attribute> for the following text. =item B<!>I<attribute> Toggle the attribute I<attribute> for the following text. =back Where I<attribute> is one of the following =over =item B<o> Draw a line over the text. =item B<u> Draw a line under the text. =back =head1 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. =head1 WWW Original (LemonBoy) L<git repository|https://github.com/LemonBoy/bar> =head1 AUTHOR 2012-2015 (C) The Lemon Man Xinerama support was kindly contributed by Stebalien RandR support was kindly contributed by jvvv Clickable areas support was heavily based off u-ra contribution Xft support was added by krypt-n Borders support was added by dark-yux Rotatable text was added by venam
