From 797126514963c751d15edfe2b1e0c5fb8627917a Mon Sep 17 00:00:00 2001 From: slotThe Date: Wed, 9 Dec 2020 19:03:07 +0100 Subject: Split out contributing and quick-start part from readme The contributing.org file also contains information on how to write a new monitor for xmobar. The quick-start guide got reworked a bit to inline similar parts. --- readme.org | 348 +------------------------------------------------------------ 1 file changed, 5 insertions(+), 343 deletions(-) (limited to 'readme.org') diff --git a/readme.org b/readme.org index 0407bce..159c8da 100644 --- a/readme.org +++ b/readme.org @@ -204,351 +204,13 @@ Since 0.14 xmobar reacts to SIGUSR1 and SIGUSR2: - After receiving SIGUSR2 xmobar repositions itself on the current screen. -* Configuration -** Quick Start +* Configuration and Further Links -See [[http://github.com/jaor/xmobar/raw/master/examples/xmobar.config][examples/xmobar.config]] for an example. +- If you want to jump straight into configuring xmobar, head over to the + [[./doc/quick-start.org][quick-start]] guide. -For the output template: - -- =%command%= will execute command and print the output. The output may - contain markups to change the characters' color. - -- =string= will print =string= with =#FF0000= color - (red). =string= will print =string= in red - with a black background (=#000000=). Background absolute offsets can - be specified for XFT fonts. =string= will - have a background matching the bar's height. - -- =string= will print string surrounded by a box in the - foreground color. The =box= tag accepts several optional arguments to - tailor its looks: - - - =type=: =Top=, =Bottom=, =VBoth= (a single line above or below - string, or both), =Left=, =Right=, =HBoth= (single vertical lines), - =Full= (a rectangle, the default). - - =color=: the color of the box lines. - - =width=: the width of the box lines. - - =offset=: an alignment char (L, C or R) followed by the amount of - pixels to offset the box lines; the alignment denotes the position - of the resulting line, with L/R meaning top/bottom for the vertical - lines, and left/right for horizontal ones. - - =mt=, =mb=, =ml=, =mr= specify margins to be added at the top, - bottom, left and right lines. - - For example, a box underlining its text with a red line of width 2: - - #+begin_src shell - string - #+end_src - - and if you wanted an underline and an overline with a margin of 2 - pixels either side: - - #+begin_src shell - string - #+end_src - -- =string= will print =string= with the first font from - =additionalFonts=. The index =0= corresponds to the standard font. - -- == will insert the given bitmap. XPM image - format is also supported when compiled with the =with_xpm= flag. - -- == will execute given command when - clicked with specified buttons. If not specified, button is equal to 1 - (left mouse button). Using old syntax (without backticks surrounding - =command=) will result in =button= attribute being ignored. - -- == allows the encapsulation of arbitrary text =str= - (which must be =len= =Char=s long, where =len= is encoded as a decimal - sequence). Careful use of this and =UnsafeStdinReader=, for example, - permits window managers to feed xmobar strings with == tags - mixed with un-trusted content (e.g. window titles). For example, if - xmobar is invoked as - - #+begin_src shell - xmobar -c "[Run UnsafeStdinReader]" -t "%UnsafeStdinReader%" - #+end_src - - and receives on standard input the line - - #+begin_src shell - foo/>` - #+end_src - - then it will display the text - =foo=, which, when clicked, will - cause =test= to be echoed. - -Other configuration options: - -- =font= Name of the font to be used. Use the =xft:= prefix for XFT - fonts. - -- =additionalFonts= Haskell-style list of fonts to be used with the - =fn=-template. Use the =xft:= prefix for XFT fonts. See also - =textOffsets= below. - -- =bgColor= Background color. - -- =fgColor= Default font color. - -- =alpha= The transparency. 0 is transparent, 255 is opaque. - -- =position= Top, TopP, TopW, TopSize, Bottom, BottomP, BottomW, - BottomSize or Static (with x, y, width and height). - - TopP and BottomP take 2 arguments: left padding and right padding. - - TopW and BottomW take 2 arguments: an alignment parameter (L for left, - C for centered, R for Right) and an integer for the percentage width - xmobar window will have in respect to the screen width. - - TopSize and BottomSize take 3 arguments: an alignment parameter, an - integer for the percentage width, and an integer for the minimum pixel - height that the xmobar window will have. - - For example: - - #+begin_src haskell - position = BottomW C 75 - #+end_src - - to place xmobar at the bottom, centered with the 75% of the screen - width. Or - - #+begin_src haskell - position = BottomP 120 0 - #+end_src - - to place xmobar at the bottom, with 120 pixel indent of the left. Or - - #+begin_src haskell - position = Static { xpos = 0 , ypos = 0, width = 1024, height = 15 } - #+end_src - - or - - #+begin_src haskell - position = Top - #+end_src - -- =textOffset= The vertical offset, in pixels, for the text baseline. If - negative or not given, xmobar will try to center text vertically. - -- =textOffsets= A list of vertical offsets, in pixels, for the text - baseline, to be used with the each of the fonts in =additionalFonts= - (if any). If negative or not given, xmobar will try to center text - vertically for that font. - -- =iconOffset= The vertical offset, in pixels, for icons bottom line. If - negative or not given, xmobar will try to center icons vertically. - -- =lowerOnStart= When True the window is sent the bottom of the window - stack initially. - -- =hideOnStart= When set to True the window is initially not mapped, - i.e. hidden. It then can be toggled manually (for example using the - dbus interface) or automatically (by a plugin) to make it reappear. - -- =allDesktops= When set to True (the default), xmobar will tell the - window manager explicitly to be shown in all desktops, by setting - =_NET_WM_DESKTOP= to 0xffffffff. - -- =overrideRedirect= If you're running xmobar in a tiling window - manager, you might need to set this option to =False= so that it - behaves as a docked application. Defaults to =True=. - -- =pickBroadest= When multiple displays are available, xmobar will - choose by default the first one to place itself. With this flag set to - =True= (the default is =False=) it will choose the broadest one - instead. - -- =persistent= When True the window status is fixed i.e. hiding or - revealing is not possible. This option can be toggled at runtime. - Defaults to False. - -- =border= TopB, TopBM, BottomB, BottomBM, FullB, FullBM or NoBorder - (default). - - TopB, BottomB, FullB take no arguments, and request drawing a border - at the top, bottom or around xmobar's window, respectively. - - TopBM, BottomBM, FullBM take an integer argument, which is the margin, - in pixels, between the border of the window and the drawn border. - -- =borderColor= Border color. - -- =borderWidth= Border width in pixels. - -- =iconRoot= Root folder where icons are stored. For == if - path start with =/=, =./= or =../= it is interpreted as it is. - Otherwise it will have - - #+begin_src haskell - iconRoot ++ "/" - #+end_src - - prepended to it. Default is =.=. - -- =commands= For setting the options of the programs to run (optional). - -- =sepChar= The character to be used for indicating commands in the - output template (default '%'). - -- =alignSep= a 2 character string for aligning text in the output - template. The text before the first character will be align to left, - the text in between the 2 characters will be centered, and the text - after the second character will be align to the right. - -- =template= The output template. - -- =wmClass= The value for the window's X11 WM_CLASS property. Defaults - to "xmobar". - -- =wmName= The value for the window's X11 WM_NAME property. Defaults to - "xmobar". - -*** Running xmobar with i3status - -xmobar can be used to display information generated by [[http://i3wm.org/i3status/][i3status]], a small -program that gathers system information and outputs it in formats -suitable for being displayed by the dzen2 status bar, wmii's status bar -or xmobar's =StdinReader=. See [[http://i3wm.org/i3status/manpage.html#_using_i3status_with_xmobar][i3status manual]] for further details. - -*** Dynamically sizing xmobar - -See [[https://github.com/jaor/xmobar/issues/239#issuecomment-233206552][this idea]] by Jonas Camillus Jeppensen for a way of adapting -dynamically xmobar's size and run it alongside a system tray widget such -as trayer or stalonetray (although the idea is not limited to trays, -really). For your convenience, there is a version of Jonas' script in -[[./examples/padding-icon.sh][examples/padding-icon.sh]]. - -** Command Line Options - -xmobar can be either configured with a configuration file or with -command line options. In the second case, the command line options will -overwrite the corresponding options set in the configuration file. - -Example: - -#+begin_src shell - xmobar -B white -a right -F blue -t '%LIPB%' -c '[Run Weather "LIPB" [] 36000]' -#+end_src - -This is the list of command line options (the output of xmobar --help): - -#+begin_src shell - Usage: xmobar [OPTION...] [FILE] - Options: - -h, -? --help This help - -v --verbose Emit verbose debugging messages - -r --recompile Force recompilation - -V --version Show version information - -f font name --font=font name Font name - -N font name --add-font=font name Add to the list of additional fonts - -w class --wmclass=class X11 WM_CLASS property - -n name --wmname=name X11 WM_NAME property - -B bg color --bgcolor=bg color The background color. Default black - -F fg color --fgcolor=fg color The foreground color. Default grey - -i path --iconroot=path Root directory for icon pattern paths. Default '.' - -A alpha --alpha=alpha Transparency: 0 is transparent, 255 is opaque. Default: 255 - -o --top Place xmobar at the top of the screen - -b --bottom Place xmobar at the bottom of the screen - -d --dock Don't override redirect from WM and function as a dock - -a alignsep --alignsep=alignsep Separators for left, center and right text - alignment. Default: '}{' - -s char --sepchar=char Character used to separate commands in - the output template. Default '%' - -t template --template=template Output template - -c commands --commands=commands List of commands to be executed - -C command --add-command=command Add to the list of commands to be executed - -x screen --screen=screen On which X screen number to start - -p position --position=position Specify position of xmobar. Same syntax as in config file - - Mail bug reports and suggestions to -#+end_src - -** The Output Template - -The output template must contain at least one command. xmobar will parse -the template and will search for the command to be executed in the -=commands= configuration option. First an =alias= will be searched -(plugins such as Weather or Network have default aliases, see below). -After that, the command name will be tried. If a command is found, the -arguments specified in the =commands= list will be used. - -If no command is found in the =commands= list, xmobar will ask the -operating system to execute a program with the name found in the -template. If the execution is not successful an error will be reported. - -It's possible to insert in the global templates icon directives of the -form: - -#+begin_src shell - -#+end_src - -which will produce the expected result. Accepted image formats are XBM -and XPM (when =with_xpm= flag is enabled). If path does not start with -=/=, =./=, =../= it will have - -#+begin_src haskell - iconRoot ++ "/" -#+end_src - -prepended to it. - -It's also possible to use action directives of the form: - -#+begin_src shell - -#+end_src - -which will be executed when clicked on with specified mouse buttons. -This tag can be nested, allowing different commands to be run depending -on button clicked. - -** The =commands= Configuration Option - -The =commands= configuration option is a list of commands information -and arguments to be used by xmobar when parsing the output template. -Each member of the list consists in a command prefixed by the =Run= -keyword. Each command has arguments to control the way xmobar is going -to execute it. - -The option consists in a list of commands separated by a comma and -enclosed by square parenthesis. - -Example: - -#+begin_src haskell - [Run Memory ["-t","Mem: %"] 10, Run Swap [] 10] -#+end_src - -to run the Memory monitor plugin with the specified template, and the -swap monitor plugin, with default options, every second. And here's an -example of a template for the commands above using an icon: - -#+begin_src haskell - template=" " -#+end_src - -This example will run "xclock" command when date is clicked: - -#+begin_src haskell - template="%date% -#+end_src - -The only internal available command is =Com= (see below Executing -External Commands). All other commands are provided by plugins. xmobar -comes with some plugins, providing a set of system monitors, a standard -input reader, an Unix named pipe reader, a configurable date plugin, and -much more: we list all available plugins below. - -Other commands can be created as plugins with the Plugin infrastructure. -See below. +- If you want to know how to write your own plugin, or how to contribute + to the xmobar project, check out [[contributing.org][contributing]]. * Authors and credits -- cgit v1.2.3
