SARAH Manager

SARAH is a global proxy for other manager. It also handle communication with Client.

  • run(name, options, callback): Run standard plugin script
  • call(name, options, callback): Like run() but DO NOT trigger RuleEngine
  • last(): Run last run command again with options
  • find(name): Retrieve the plugin object according to it's name
  • exists(name): Check if the plugin is available
  • speak(tts, callbackSync): Ask client text to speech
  • answer(callbackSync): Like (speak) with predefined answers
  • shutup(once): Ask client to stop ALL (or once) speaking
  • play(path, callbackSync): Play given path
  • stop(path): Stop given path
  • run(path, options): launch process with given path and parameters
  • activate(name): set to foreground given application name
  • keyText(text): send key stroke with modifier
  • keyUp(char, mod): send key stroke with modifier
  • keyDown(char, mod): send key stroke with modifier
  • keyPress(char, mod): send key stroke with modifier
  • face(pause): start/stop face recognition
  • gesture(pause): start/stop gesture recognition
  • listen(pause): start/stop listening
  • picture(device, path): take a picture and store
  • recognize(path): perform speech recognition on given file / upload
  • context([names]): set the context grammar
  • grammar(xml): Send a XML (inside a rule) to override a grammar
  • askme(tts, grammar, timeout, callback): Speak TTS, Set a dynamic grammar (key/value), ask twice if there is timeout, then call callback(answer, next)
  • listen(event, callback): Listen to a given event
  • trigger(event, data): Send a given event
  • asknext(rule, options): Call given rule's example with options

AskNext

The SARAH.AskNext() build a dynamic grammar and wait for an answer. Use '*' for wildcards.

SARAH.askme("What is your favorite sound", {

  "I feel good"     : 'feelgood',
  "Highway to hell" : 'ACDC',
  "*"               : '*'

}, 10000, function(answer, end){
  SARAH.call('xbmc', { 'song' : answer }, function(options){ end(); });
});

LangManager

The i18n() function is a global translate feature that relies on /locales JSON translation.

  • Plugins can have a /locale/fr.js for their translations
  • Use answer() to move answers to an XML grammar

Portal Manager

Portal Manager handle all Web GUI features. It also handle the Dashboard.

Libraries

Layouts

The site render pages templates using EJS engine. New pages should relies on layout.ejs template.

Modal

Confirm

A little help that popup to confirm an action if the DOM element contains .confirm class

<button type="submit" class="btn btn-default confirm">Click Me</button>

Ajax

TBW.

Config Manager

Config Manager handle configuration of core and plugins.

  • server/server.prop are root properties
  • {plugins}/{plugin}/{plugin}.prop are plugin's root properties
  • data/custom.prop are user properties

Config is a global JSON object merging all property files. DO NOT put password in server.prop or {plugin}.prop ONLY custom.prop.

Update and Save

Configuration object should NEVER be cloned but only updated and saved using following code:

Config.bot.name = 'J.A.R.V.I.S';
SARAH.ConfigManager.save();

A POST to /plugin/config/:name?modules.param=value can peform a plugin update.

Plugin Manager

Plugin Manager handle plugin life cycle, marketplace and installation. Plugins folder is defined by Shell ENV var: PATH_PLUGINS

Install

Use the Store to download or install plugins from marketplace. Otherwise create plugin from a template.

  • {plugin}.xml : The client XML grammar
  • {plugin}_en_US.xml : The client XML grammar in english
  • {plugin}.js : The server script
  • {plugin}.prop : The script properties

Plugin's Server libraries

  • node_modules/ : All the nodejs custom libraries (use NPM)

Plugin's WWW

  • portlet.ejs : Custom portlet template
  • index.ejs : Custom documentation opened in a modal
  • {plugin}.ejs : Custom dynamic webpage
  • www/ : Contains all web resources served as static files

Plugin's locale

  • locales/ : All the translations
  • locales/en.js : English translations for i18n()
  • locales/fr.js : French translation for i18n()

Life cycle

TBW.

Migration SARAH 3.x to 4.x

All plugin's static web resources MUST be in /{plugin}/www/*.

{plugin}.js

SARAH and Config are now global variables.

Rename exports.action(data, callback, config, SARAH) to exports.action(data, next). (In JavaScript function parameter can be named as you want)

portlet.ejs

The portlet.ejs will replace portlet.html. Name is different for backward compatibility. The portlet_back.html is no more...

index.ejs

The index.ejs will replace index.html. Name is different for backward compatibility. It's now a modal ! Bootstrap grid is no longer required. Use <h3> and <h4> for title.

{plugin}.css

Portal DOM has changed. There is no more gridster. SARAH v4.x provides LESS compilator. The /www/less/{plugin}.less will replace the {plugin}.css.

{plugin}.xml

  • Remove <example> tags that are now a new way to speak using SARAH.asknext().
  • Remove weight no longer relevant
  • There is to DTD: semantics/1.0 and semantics-ms/1.0 the first one use out.* the second use $. It seems to be the same code but semantics-ms may have access to windows built-in grammars...

Profile Manager

Manage profiling of current users

  • Clean and attach Profile JSON object to request
  • Store latest used profile
