ECMA Script Interaction With Plasma Shells

It is possible to control and interact with a Plasma user interface shell such as a plasma-desktop or (starting in KDE SC 4.5) plasma-netbook session using ECMA Script (aka JavaScript). This scripting mechanism exposes containments (Desktop Activities and Panels), widgets and various other aspects of plasma-desktop configuration using the widely known and used ECMA Script language. The QtScript engine is used for the runtime environment.

This document describes the API that is provided along with how to run such scripts in plasma-desktop.

Examples

A set of examples can be found here that demonstrate the use of various aspects of Plasma shell scripting.

Contributions of additional examples are welcome and can be sent to the Plasma development mailing list (plasma-devel at kde.org) for inclusion if you do not have commit rights to the kdeexamples module.

Advanced example: Adding a widget to the System Tray

var widgetName = "org.kde.plasma.printmanager";

for (i = 0; i < panelIds.length; ++i) { //search through the panels
    panel = panelById(pids[i]);
    if (!panel) continue;

    for (tmpIndex = 0; tmpIndex < panel.widgetIds.length; tmpIndex ++) {
        appletWidget = panel.widgetById(panel.widgetIds[tmpIndex]);

        if (appletWidget.type == "org.kde.plasma.systemtray") {
            systemtrayId = appletWidget.readConfig("SystrayContainmentId");
            if (systemtrayId) {
               print("systemtray id: " + systemtrayId)
               var systray = desktopById(systemtrayId);
               systray.currentConfigGroup = ["General"];
               var extraItems = systray.readConfig("extraItems").split(",");
               if (extraItems.indexOf(widgetName) === -1) {
                   extraItems.push(widgetName)
                   systray.writeConfig("extraItems", extraItems);
                   systray.reloadConfig();
               }
            }          
        }
    }
}

Running Scripts

There are three ways that scripts can be executed in plasma-desktop:

  • on first run: when plasma-desktop is started without any pre-existing configuration, any scripts in $APPDATA/plasma-desktop/init/ with a ".js" suffix are run. If there is more than one script, they are run sequentially in the alphabetical order of the file names.

Note

For security reasons, scripts located in the user's home directory will not be run during this phase.


  • on update: when plasma-desktop is started, it will check in
`kde4-config --path data`/plasma-desktop/updates/

with a ".js" suffix for scripts that have not yet been run. If there is more than one script which has not been run yet they will be executed serially in the alphabetical order of the file names.

A record of which update scripts have been run is kept in the application's config file in the [Updates] group. This means that if the plasma-desktop configuration file is removed, all the update scripts will be run again.

Note

For security reasons, scripts located in the user's home directory will not be run during this phase.


  • interactively: an interactive scripting dialog can be requested either via the KRunner window (Alt+F2, by default, or via the "Run Command" entry in various desktop menus) by entering "desktop console" as the search term. It can also be triggered directly via dbus with 
    qdbus org.kde.plasma-desktop /MainApplication showInteractiveConsole
    In Plasma 5 use 
    qdbus org.kde.plasmashell /PlasmaShell org.kde.PlasmaShell.showInteractiveConsole


Note

This method is not available for plasma-netbook.


ECMA Script may be entered directly into this window for execution and output appears in the lower half of the window. Ctrl+E is a shortcut to run scripts, and scripts can be saved to and loaded from disk.
Scripts from files can also be loaded using KRunner with "desktop console /path/to/file" or via dbus with
qdbus org.kde.plasma-desktop /MainApplication loadScriptInInteractiveConsole /path/to/file

Templates

Templates are named packages that contain scripts. This provides a way for common functionality to be easily reused, helping to increase consistency and lower maintenance costs. Templates can be loaded from other scripts by name and they are also used to populate some parts of the user interface, such as the entries in the Add Panels menu.

A template is a small set of files in a specified file hierarchy (or, in Plasma terms, a "Package"). In particular, a Template package contains the following files:

  • metadata.desktop: a .desktop file describing the template
  • contents/layout.js: a Javascript file containing the actual script

Templates are stored under share/apps/plasma/layout-templates and may be installed using `plasmapkg -t layout-template -i /path/to/package`. Template packages may also be provided as a .zip file with a .plasmalayout suffix.

The metadata.desktop file contains the usual .desktop entries such as Name and Icon but must also contain Type=Service and ServiceTypes=Plasma/LayoutTemplate entries. If the layout is specific to a given Plasma application, such as plasma-desktop, this can be specific using X-Plasma-Shell. X-Plasma-ContainmentCategories defines what kind of layout it is with possible values being panel and desktop. Finally a X-KDE-PluginInfo-Name entry is required to provide a globally unique internal name for the Template. Here is an example of a Template that provides a Panel layout for Plasma Netbook: 

[Desktop Entry]
Encoding=UTF-8
Name=Cool Panel
Type=Service
ServiceTypes=Plasma/LayoutTemplate
X-Plasma-Shell=plasma-netbook
X-Plasma-ContainmentCategories=panel
X-KDE-PluginInfo-Author=Aaron Seigo
X-KDE-PluginInfo-Email=aseigo@kde.org
X-KDE-PluginInfo-Name=org.kde.CoolNetbookPanel
X-KDE-PluginInfo-Version=1.0
X-KDE-PluginInfo-Website=http://plasma.kde.org/
X-KDE-PluginInfo-Category=
X-KDE-PluginInfo-Depends=
X-KDE-PluginInfo-License=GPL
X-KDE-PluginInfo-EnabledByDefault=true

When running a template, two global variables will be accessible in read-only mode: templateName and templateComment. They will contain the Name and Comment fields of the above desktop file, and are translated if a localization is available.

Examples of Usage

Creating panels

A good example of the use of templates is the use case that triggered the creation of this feature: the desire to make it easy for users to re-create the default panel that is created on the first start. There is a Template called org.kde.plasma-desktop.defaultPanel that ships with the KDE Plasma Workspace which contains the layout for the initial default panel. This is referenced by the default Plasma Desktop init script and because it is marked as a Panel Template in the metadata.desktop file it also shows up to the user in the Add Panels menu. When selected by the user from the menu, the exact same panel that is created on desktop start up is created for them, complete with Plasma Widgets and configuration.

Automating tasks

Another example of the usefulness of templates is the "Find Widgets" template. This template, which first shipped with Plasma Desktop v4.5, provides a function for finding widgets by name. It appears in the toolbar "Load" and "Use" menus in the Desktop Console in plasma-desktop, and makes finding widgets as simple as: 

var template = loadTemplate('org.kde.plasma-desktop.findWidgets')
template.findWidgets('systemtray')


Since just finding the widget is not enough, you can connect a callback to do additional operations, such as removing the widget : 

removeWidget = function(widget, containment)
{
  widget.remove()
}

var template = loadTemplate('org.kde.plasma-desktop.findWidgets')
template.findWidgets('systemtray', removeWidget)


Activity templates

Probably the most user visible use of templates are "Activity templates". The structure of Activity templates is similar to the other use of templates, but a few extra features are provided in the metadata.desktop file. Here is an example of such an activity template: 

[Desktop Entry]
Encoding=UTF-8
Name=Cool Activity Template
Icon=user-desktop
Type=Service
ServiceTypes=Plasma/LayoutTemplate
X-Plasma-Shell=plasma-desktop
X-Plasma-ContainmentCategories=desktop
X-Plasma-ContainmentLayout-ExecuteOnCreation=dolphin $desktop, gwenview $pictures
X-Plasma-ContainmentLayout-ShowAsExisting=true
X-KDE-PluginInfo-Author=John Doe
X-KDE-PluginInfo-Email=john@doe.org
X-KDE-PluginInfo-Name=org.kde.plasma-desktop.CoolTemplate
X-KDE-PluginInfo-Version=1.0
X-KDE-PluginInfo-Website=http://john.doe.org
X-KDE-PluginInfo-Category=
X-KDE-PluginInfo-Depends=
X-KDE-PluginInfo-License=GPL
X-KDE-PluginInfo-EnabledByDefault=true

The layout itself is still created from the layout.js file as usual, but this template also shows as a precreated activity to the user thanks to the X-Plasma-ContainmentLayout-ShowAsExisting key. Additionally, it starts applications in the newly created activity using the X-Plasma-ContainmentLayout-ExecuteOnCreation key.

That key is a list of commands to execute, and it supports the following variables:

  • $desktop
  • $autostart
  • $documents
  • $music
  • $video
  • $downloads
  • $pictures

They all expand into the path toward the user corresponding default folder.

Update scripts

Update javascript scripts can be added per-shell at the location 

  share/plasma/shells/org.kde.plasma.desktop/updates/

The API available from those config files is the same available from the normal init.js file. from there is possible to add or remove applets or modify config values.

Look and Feel dependent default setup for applets

The look and feel package can contain JavaScript files to override the default configuration for applets, if distributions or system integrators want to have a different default setup. The JS files are located under the L&F package folder, for instance 

  /opt/kde5/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/plasmoidsetupscripts/org.kde.plasma.analogclock.js

The API available is the same as the init.js script, with the addition of the global variables applet and containment that point to the instance of the applet and the instance of the containment the applet is in. In the case of a containment, the variables applet and containment will be the same.

API

In addition to the normal ECMA Script API and the Qt-specific extensions (such as signal/slot support) provided by QtScript, the following API is provided for use by scripts.

All of the API below, unless otherwise noted with a version noticed, appear as below in the KDE Software Compilation v4.4.0 and later. API that is not noted as being part of a given class or object is part of the global namespace.

Note

API compatibility is guaranteed from version to version starting with KDE Software Compilation v4.4.0.


Version Numbers

Starting with KDE SC 4.5, the version number of both the scripting API and the application is available to the script via the following read-only properties:

  • String applicationVersion: the version of the application, e.g. 0.3
  • String platformVersion: the version of the KDE Platform, e.g. 0.3
  • number scriptingVersion: the version of the scripting API; e.g. in KDE SC 4.5 this is 2

Activities and desktops

Desktop are the desktop layer in a plasma-desktop session and may contain widgets. In sightly more technical terms, they are desktop containments. Activities can be created, enumerated, modified and destroyed.

New Activities can be created using the newActivity function, like this: 

var activityId = newActivity("org.kde.plasma.folderview")

it returns the activity string Id (to not be confused from the numerical id of the Deskop object) The string passed into the constructor maps to the X-KDE-PluginInfo-Name= entry in the plugin's .desktop file). See the documentation on the Containment object class below.

Read-only properties:

  • Array[number] activityIds: returns a list of integer ids of all existing Plasma activities
  • Array[String] knownActivityTypes: (scripting version >= 2) a list of types of activities that can be created. This is useful to check if an Activity type is available on the system before trying to construct one.

Functions:

  • Array[Desktop] desktopsForActivity(string id): return all the desktops associated to a specific activity id (one per phisical screen)
  • Desktop desktopById(number id): return an object representing the activity with the given id
  • Desktop desktopForScreen(number screen[, number dekstop]): returns an object representing the activity currently associated with the given screen and, optionally, the given desktop.
  • Array[Desktop] desktops(): returns an array of all desktops that currently exist
  • Array[string] activities(): returns an array of all activity ids of the activities that currently exist

Panels

Panels can be created, enumerated, modified and destroyed. A panel object combines both a containment as well as the container itself, allowing for full control of things such as where it appears on the screen and the hiding features associated with them.

New Panels can be created using the Panel constructor, like this: 

var panel = new Panel("dock")

The string passed into the constructor maps to the X-KDE-PluginInfo-Name= entry in the plugin's .desktop file).

Read-only properties:

  • Array[number] panelIds: returns a list of integer ids of all existing Plasma panels
  • Array[String] knownPanelTypes: (scripting version >= 2) a list of types of panels that can be created. This is useful to check if a Panel type is available on the system before trying to construct one.

Functions:

  • Panel panelById(int id): returns an object representing the Panel that matches the given id
  • Array[Panels] panels(): returns an array of all panels that currently exist

Activities and Panels

Activity and Panel objects, once created by the script, or as returned by activityById, activityForScreen, or panelById) provide the following read-only properties:

  • number id: the integer id of this activity
  • String formFactor: returns the form factor of the activity, e.g. "planar" for most desktop activities,"mediacenter" for media centers and either "horizontal" or "vertical" for panels.
  • Array[number] widgetIds: a list of integer ids of all the widgets in this Activity
  • Array[String] configKeys: (scriptingVersion >= 2) a list of all keys that are set in the current configuration group
  • Array[String] configGroups: (scriptingVersion >= 2) a list of all the groups in the current configuration group
  • Array[String] globalConfigKeys: (scriptingVersion >= 2) a list of all keys that are set in the current global configuration group
  • Array[String] globalConfigGroups: (scriptingVersion >= 2) a list of all the groups in the current global configuration group

as well as the following read/write properties:

  • number desktop: the virtual desktop this activity is associated with, or -1 for none
  • number screen: the screen this activity is associated with, or -1 for none
  • String name: the name of this activity
  • String wallpaperPlugin: (scriptingVersion >= 2) the wallpaper plugin to use with the Activity
  • String wallpaperMode: (scriptingVersion >= 2) the wallpaper plugin mode to use with the Activity
  • Array[String] currentConfigGroup: (scriptingVersion >= 2) the current configuration group path, with each entry in the array representing a sub-group. This allows one to access trees of groups with code such as: widget.currentConfigGroup = new Array('topGroup', 'subGroupOfTopGroup'). An empty Array means the default (top-level) configuration group for the widget
  • String version: (scriptingVersion >= 2) the version of the Activity or Panel

and the following methods:

  • remove(): deletes this activity and all widgets inside of it
  • Widget widgetById(number id): returns an object representing the widget with the given id
  • Widget addWidget(String name): adds a new widget to the activity; the name maps to the X-KDE-PluginInfo-Name= entry in the widget's .desktop file
  • Widget addWidget(Widget widget): adds an existing widget to this activity; useful for moving widgets between Activities and Panels
  • showConfigurationInteface(): shows the configuration user interface for this Activity or Panel on the screen
  • readConfig(String key, any default): (scriptingVersion >= 2) reads the value of key in the config with default for the default value
  • writeConfig(String key, any value): (scriptingVersion >= 2) sets key to value in the config
  • readGlobalConfig(String key, any default): (scriptingVersion >= 2) reads the value of key in the global config with default for the default value
  • writeGlobalConfig(String key, any value): (scriptingVersion >= 2) sets key to value in the global config
  • reloadConfig(): (scriptingVersion >= 2) causes the Activity or Panel to reload its configuration; reaction to configuration changes made using readConfig are usually activated on script exit, but this can be triggered earlier on a per-widget basis using this method
  • Array[String] currentGlobalConfigGroup: (scriptingVersion >= 2) the current global configuration group path, with each entry in the array representing a sub-group, similar to currentConfigGroup. However, global configuration is shared by all instances of panels and activities of the same type.
  • Array[Widget] widgets([String type]): (scriptingVersion >= 2) returns all the widgets in the Panel or Activity. If the optional type is specified, only widgets matching that type will be returned.

In addition to all of the above properties and functions, Panel objects also provide the folowing read/write properties:

  • number length: the number of pixels along the screen edge used
  • number minimumLength: (scriptingVersion >= 7) the minimum number of pixels along the screen edge used (auto-resize panels)
  • number maximumLength: (scriptingVersion >= 7) the maximum number of pixels along the screen edge used (auto-resize panels)
  • number height: the height (or for vertical panels, the width) of the panel
  • String hiding: the hiding mode of the panel, one of "none" (for no hiding), "autohide", "windowscover" or "windowsbelow"
  • String alignment: right, left or center alignment of the panel (for vertical panels, right corrsponds to top and left to bottom)
  • String location: returns the location of the activity (only relevant for Panels); valid values include "top", "bottom", "left", "right" and "floating"

Widgets

Widgets may be enumerated by calling the widgetIds property on an Activity or Panel object. With a widget id in hand, a Widget object can be retrieved by calling widgetById(id) on an Activity or Panel object. New Widgets can be created with add addWidget(String) function provided by Activity and Panel objects.

Checking if a widget is installed

A list of all installed widget types can be retrieved the following read-only property:

  • Array[String] knownWidgetTypes (scripting version >= 2)

This can be used most conveniently with the indexOf() method, like this: 

if (knownWidgetTypes.indexOf('someWidgetPluginName') > -1) {
    print("It is installed on this system!");
} else {
    print("It is not installed :(");
}

Widget Object API

A Widget object provides the following read-only properties:

  • number id: the id of the widget
  • String type: the plugin type of this widget
  • Array[String] configKeys: a list of all keys that are set in the current configuration
  • Array[String] configGroups: a list of all the groups in the current configuration
  • Array[String] globalConfigKeys: (scriptingVersion >= 2) a list of all keys that are set in the current global configuration group
  • Array[String] globalConfigGroups: (scriptingVersion >= 2) a list of all the groups in the current global configuration group
  • String version: (scriptingVersion >= 2) the version of the Activity or Panel

as well as the following read-write properties:

  • Array[String] currentConfigGroup: the current configuration group path, with each entry in the array representing a sub-group. This allows one to access trees of groups with code such as: widget.currentConfigGroup = new Array('topGroup', 'subGroupOfTopGroup'). An empty Array means the default (top-level) configuration group for the widget
  • Array[String] currentGlobalConfigGroup: (scriptingVersion >= 2) the current global configuration group path, with each entry in the array representing a sub-group, similar to currentConfigGroup. However, global configuration is shared by all instances of widgets of the same type.
  • QRectF geometry: the geometry of the widget (settable)
  • String globalShortcut: the shortcut sequence (in the format used by QKeySequence, e.g. "Alt+F1") associated with this widget
  • number index: the layout index of the widget; in a Panel this corresponds to the order the widget appears in. Changing the value of the index will change the position of the widget in Panels and may do so in some Activities as well.

and the following methods:

  • remove(): deletes this widget
  • readConfig(String key, any default): reads the value of key in the config with default for the default value
  • writeConfig(String key, any value): sets key to value in the config
  • readGlobalConfig(String key, any default): (scriptingVersion >= 2) reads the value of key in the global config with default for the default value
  • writeGlobalConfig(String key, any value): (scriptingVersion >= 2) sets key to value in the global config
  • reloadConfig(): causes the widget to reload its configuration; reaction to configuration changes made using readConfig are usually activated on script exit, but this can be triggered earlier on a per-widget basis using this method
  • showConfigurationInteface(): shows the configuration user interface for this widget on the screen

Screen Geometry

Read-only properties:

  • number screenCount: returns the number of screens connected to the computer

Functions:

  • QRectF screenGeometry(number screen): returns a rect object representing the geometry of a screen

Wallpaper Plugins

  • Array[String => Array[String]] knownWallpaperPlugins(): (scripting version >= 4) returns a list of all installed wallpaper plugins. The keys of the array are the wallpaper plugin names. The values are arrays containing the modes available for that wallpaper plugin. The mode array may be empty, as most wallpaper plugins only offer one mode.

Locating Applications and Paths

  • boolean applicationExists(String name): (scripting version >= 4) searches $PATH first, then tries in the application menu system by application storage name (aka the .desktop file name), then Name= entries for apps with installed .desktop files, then GenericName= entries for same
  • mixed defaultApplication(String kind [, boolean storageId = false]): (scripting version >= 4) returns the executable (or if storageId is true, then the app menu system id, e.g. its .desktop file name) of the default app. The "kind" parameter may be a well-known application type including "browser", "mailer", "filemanager", "terminal", "imClient" and "windowmanager" (or any other entry in share/apps/kcm_componentchooser/kcm_*.desktop); it may also be a mimetype (e.g. "application/pdf"). On failure, it returns false.
  • String applicationPath(String name): (scripting version >= 4) returns the full local path to a given application or .desktop file if it exists. Example:
var desktopfile = "firefox.desktop"
var executable  = "firefox"
if (applicationExists(executable)) {  
    print (executable + " exists " + " with this path:  " + applicationPath(executable))
    print (executable + " .desktop file is located here :    " + applicationPath(desktopfile))
} else{
    print (executable + " does not exist ")
}
  • String userDataPath([String type, String path]): (scripting version >= 4) returns the default path for user data. Called with no parameters, it returns the user's home directory.

    • documents
    • music
    • video
    • downloads
    • pictures
    • autostart
    • desktop (should be considered deprecated for Plasma workspaces)

If a second string is passed in, it is considered a request for a specific path and the following types are recognized:

    • apps - Applications menu (.desktop files).
    • autostart - Autostart directories (both XDG and kde-specific)
    • cache - Cached information (e.g. favicons, web-pages)
    • cgi - CGIs to run from kdehelp.

    • icon - Icons, see KIconLoader.
    • kcfg - KConfigXT config files.
    • lib - Libraries.
    • locale - Translation files for KLocale.
    • mime - Mime types defined by KDE-specific .desktop files.
    • module - Module (dynamically loaded library).
    • qtplugins - Qt plugins (dynamically loaded objects for Qt)
    • services - Services.
    • servicetypes - Service types.
    • sound - Application sounds.
    • templates - Templates for the "Create new file" functionality.
    • wallpaper - Wallpapers.

    • xdgdata-icon - Freedesktop.org standard location for icons.
    • xdgdata-pixmap - Gnome-compatibility location for pixmaps.

The second parameter should be a specific resource to find the path to. An example might be userDataPath("data", "plasma-desktop").

External Configuration Files

Scripting version >=6

Access to configuration files outside of the application's appletsrc file is provided by the ConfigFile object which has the following constructors:

  • ConfigFile(ConfigFile other): creates a new ConfigFile object with the first as its parent, which automatically makes all groups of this object child groups of that parent
  • ConfigFile(string file[, string group]): creates a new ConfigFile object for file and optionally set to group group

ConfigFile has the following functions:

  • writeEntry(string key, any value): writes value for key in the current group
  • readEntry(string key): returns the value of key in the current group
  • deleteEntry(key): deletes key in the current group

ConfigFile has the following read/write properties:

  • file: the name of the configuration file. May be an absolute path or just a file name to be located automatically in the system's configuration repository.
  • group: the name of the current group. To get to child groups, create a new ConfigFile with another ConfigFile as its parent.

ConfigFile has the follow read-only properties:

  • entryList: all the keys in the current group
  • groupList: all the child groups in the current group

Example usage: 

// open the kickoffrc file
var config = ConfigFile('kickoffrc');
// switch to the RecentlyUsed group
config.group = 'RecentlyUsed';
// write an entry into it
config.writeEntry('MaxApplications', 25);

// now put Yes=20 into RecentlyUsed/Test
var config2 = ConfigFile(config, 'Test);
config2.writeEntry('Yes', 20);
