Genmon

About

This plugin cyclically spawns the indicated script/program, captures its output (stdout) and displays the resulting string into the panel.

The string can also contain markup to displayed an image, a bar, a button and a personalized tooltip.

Usage

If you want the plugin to display only text (original version), enter the command in the Command field of the Properties section of the plugin.

XML Tags

If you want the plugin to display a personalized Image or Tooltip or Bar or Button, you should develop (or get) a script returning a XML string, and enter the path of this script in the Command field of the Property section of the plugin.

The XML tags which can be used:

  • <txt>Text to display</txt>
  • <img>Path to the image to display</img>
  • <tool>Tooltip text</tool>
  • <bar>Pourcentage to display in the bar</bar>
  • <click>The command to be executed when clicking on the image</click>
  • <txtclick>The command to be executed when clicking on the text</txtclick>

If None of the tags are detected in the result of the command, the plugin returns to its original behaviour (displaying the result of the command).

Example Script

Here's a simple example of a plugin displaying the Temp of the CPU in the panel (with an icon) and the Freq in a Tooltip:

#!/bin/bash
echo "<img>/usr/share/icons/Bluecurve/16x16/apps/gnome-monitor.png</img>"
declare -i cpuFreq
cpuFreq=$(cat /proc/cpuinfo | grep "cpu MHz" | sed 's/\ \ */ /g' | cut -f3 -d" " | cut -f1 -d".")
if [ $cpuFreq -ge 1000 ]
then
  cpu=$(echo $cpuFreq | cut -c1).$(echo $cpuFreq | cut -c2)GHz
else
  cpu=${cpuFreq}MHz
fi
echo "<txt>"$(cat /proc/acpi/thermal_zone/THM/temperature | sed 's/\ \ */ /g' | cut -f2 -d" ")" C</txt>"
echo "<tool>Freq: "$cpu"</tool>"

PS: Depending on your configuration, you should change the image path.

More scripts are available at: http://git.xfce.org/panel-plugins/xfce4-genmon-plugin/tree/scripts.

Pango Markups in the <txt> tag

The <txt> tag supports Pango Markups. See: https://developer.gnome.org/pango/stable/PangoMarkupFormat.html. With Pango markups, you can change text attributes like font colour, weight, size, etc, in your output string. To do so, use the <span></span> tag within the <txt></txt> tags. For example, to display the output in bold red, you could use something like:

echo "<txt><span weight='Bold' fgcolor='Red'>Test</span></txt>"

Refer to the previous link for information on all of the properties that can be set.

Refreshing the plugin

The xfce4-genmon-plugin now supports xfce4-panel plugin-event functionality. Currently it only supports the “refresh” action which resets the timer and causes the associated command to execute again. You can use this command remotely or at the end of a script to force the panel plugin to refresh.

To refresh the plugin, issue the command:

xfce4-panel --plugin-event=genmon-X:refresh:bool:true    

where “genmon-X” is the widget name of the particular genmon instance. To get this name, go to the panel properties screen and on the Items tab, hover your mouse over the genmon plugin to get it's internal name.

Enhanced Gtk3 CSS Styling Capabilities (dev-only)

CSS styling capabilities have been enhanced by providing style classes for all elements of the plugin that can be styled via themes or individual overrides (~/.config/gtk-3.0/gtk.css). For more information, see: https://git.xfce.org/panel-plugins/xfce4-genmon-plugin/tree/CSS%20Styling.txt.

(*dev-only) functionality is currently only available in the git tree and has not yet been officially released
