--
--We use java ServiceLoader to register stuff. Here is a small example how a LanguageServerExtension is registered via a ServiceLoader and how it is used:
--
--== Register LanguageServerExtensions (ServiceLoader Example) ==
--
--This is a LanguageServerExtension. It has to be used in the de.cau.cs.kieler.language.server plugin. Since the language-server-plugin should not have dependencies to all plugins that define a language server extension dependency inversion is used to prevent that. A ServiceLoader does exactly that.
--
--Here is such an example extension, the KiCoolLanguageServerExtension:
--
--{{code}}
--package de.cau.cs.kieler.kicool.ide.language.server
--
--
--/**
-- * @author really fancy name
-- *
-- */
--@Singleton
--class KiCoolLanguageServerExtension implements ILanguageServerExtension, CommandExtension, ILanguageClientProvider {
--	// fancy extension stuff
--
--	var KeithLanguageClient client
--	// A language server extension must implement the initialize method,
--	// it is however only called if the extension is registered via a language.
--	// This should never be the case, so this is never called.
--    override initialize(ILanguageServerAccess access) {
--        this.languageServerAccess = access
--    }
--
--	// implement ILanguageClientProvider
--    override setLanguageClient(LanguageClient client) {
--        this.client = client as KeithLanguageClient
--    }
--
--	// implement ILanguageClientProvider
--    override getLanguageClient() {
--        return this.client
--    }
--
--}
--{{/code}}
--
--The CommandExtension defines all commands (requests or notifications) that are send from client to server. An example how this looks like can be seen in the code snippet Example CommandExtension is an example how to [[define a server side extension interface.>>doc:||anchor="Registeranextension(onserverside)"]]
--
--The ILanguageClientProvider should be implemented by an extension that plans to send [[messages from the server to the client>>doc:||anchor="ServerClientcommunicationinterface"]].
--
--This language server extension is provided by a corresponding contribution, which is later used to access it:
--
--{{code}}
--package de.cau.cs.kieler.kicool.ide.language.server
--
--import com.google.inject.Injector
--import de.cau.cs.kieler.language.server.ILanguageServerContribution
--
--/**
-- * @author really fancy name
-- *
-- */
--class KiCoolLanguageServerContribution implements ILanguageServerContribution {
--
--    override getLanguageServerExtension(Injector injector) {
--        return injector.getInstance(KiCoolLanguageServerExtension)
--    }
--}
--{{/code}}
--
--Create a file called de.cau.cs.kieler.language.server.ILanguageServerContribution in <plugin>/META-INF/services/ (in this example this is de.cau.cs.kieler.kicool.ide). The name of the file refers to the contribution interface that should be used to provide the contribution. The content of the file is the following:
--
--{{code}}
--de.cau.cs.kieler.kicool.ide.language.server.KiCoolLanguageServerContribution
--{{/code}}
--
--This is the fully qualified name of the contribution written earlier.
--
--The language server uses all LanguageServerExtensions like this:
--
--{{code}}
--var iLanguageServerExtensions = <Object>newArrayList(languageServer) // list of all language server extensions
--for (lse : KielerServiceLoader.load(ILanguageServerContribution)) { // load all contributions
--	iLanguageServerExtensions.add(lse.getLanguageServerExtension(injector))
--}
--{{/code}}
--
--The resulting list of implementions is used to add the extensions to the language server.
--
--== Register an extension (on server side) ==
--
--See example above for ServiceLoader and initial stuff.
--
--What is still missing are the contents of the CommandExtension implemented by the KiCoolLanguageServerExtension. This is an interface defining all additional commands. The CommandExtension looks like this.
--
--{{code title="Example CommandExtension"}}
--package de.cau.cs.kieler.kicool.ide.language.server

--This defines three json-rpc commands: "keith/kicool/compile", "keith/kicool/show", "keith/kicool/get-systems". These are implemented in KiCoolLanguageServerExtension.

--You can send a request or a notification to the language server like this:

--client.languageClient.then(lClient => {
--lClient.sendRequest("keith/kicool/compile").then((snapshotsDescriptions: CodeContainer) => {
--	// very important stuff
--}
--// await is preferred, since it is shorter.

In another console you run yarn run socket in keith-app-electron. Now refreshing your browser is enough to apply the changes.

++)))
--Add "keith-<your extension name>(% style="color: rgb(0,0,0);" %)": (%%)"0.1.0"(% style="color: rgb(0,0,0);" %) to the dependencies in the top level package.json and the product package.json files (e.g. the package.json in keith-app).
--
--=== What is in the src directory? ===
--
--The source directory has three optional subfolders.
--
--* node: Holds all backend related classes. This does currently only exist in the [[keith-language package>>url:https://git.rtsys.informatik.uni-kiel.de/projects/KIELER/repos/keith/browse/keith-language||shape="rect"]].
--* common: Holds general helper methods, string constants and some data classes
--* browser: Holds all widgets, contribution for commands, menus, and widgets, and the frontend-extension.
--
--==== The frontend-extension ====
--
--This binds all necessary classes. Look at existing frontend extension in [[KEITH>>url:https://git.rtsys.informatik.uni-kiel.de/projects/KIELER/repos/keith/browse||shape="rect"]] or [[Theia>>url:https://github.com/theia-ide/theia/tree/master/packages||shape="rect"]] to see how this is done.
--
--==== More examples for stuff ====
--
--See [[Theia examples>>url:https://www.theia-ide.org/doc/Commands_Keybindings.html||shape="rect"]].
--
--== How to write a widget ==
--
--There are different kinds of widgets that are commonly used in [[KEITH>>url:https://git.rtsys.informatik.uni-kiel.de/projects/KIELER/repos/keith/browse||shape="rect"]] or in existing [[Theia packages>>url:https://github.com/theia-ide/theia/tree/master/packages||shape="rect"]].
--
--* BaseWidget: Very basic
--* ReactWidget: A render method has to be implemented that redraws the widget on demand. Additionally several on* event methods can beimplemented.
--* TreeWidget: Extends the ReactWidget and draws the contents of the widget in a tree view.
--
--If a widget has a state it should implement the StatefulWidget interface, which allows to imlement a store and restore method.
--
--Look at examples in KEITH or Theia to see how this is done.
--
--== How to make a new module for sprotty (see actionModule, ...) ==
--
--WIP
