Thank you for help for the development of *Chat Overflow*.
While plugins live in their own project, source connections (e.g. to platform like Twitch or Discord) exist in the framework itself.
By this, we can make sure that everyone profits from the new possibilites.

This wiki entry tries to show you the different steps needed to implement a new connection.

1. Add new types to the API (Also register them in the requirement Input/Output section)
2. Create a new package in the framework services package and implement the source specific connector
3. Create a impl package and implement the types you added in the API
3. Create a impl package and implement the types you have added in the API

## Add new types to the API

Add all needed data transfer objects in `org.codeoverflow.chatoverflow.api.io.dto` and interfaces representing input / output to the correct API package. E.g. a chat input belongs to `org.codeoverflow.chatoverflow.api.io.input.chat` and should extend `ChatInput`.

We require you to also register your new type in the corresponding requirement class located in `org.codeoverflow.chatoverflow.api.plugin.configuration`. Yes, this step could be automated by using reflection. But by providing a clean interface to the plugin developer we protect type safety.

1. Execute the IntelliJ run configuration `[Deploy] Generate Bootstrap Launcher and deploy` or run the make target with `make bootstrap_deploy`. This updates the `dependencies.xml`-file in the bootstrap-project with the current dependencies, bundles everything and copies it along with start scripts, the license and a readme to the `deploy`-folder. Magic.
2. Navigate to the `deploy`-folder and run the bootstrap launcher with `java -jar ChatOverflow.jar`. After downloading all libraries, a standalone version of Chat Overflow should be started.

A release of chat overflow is simply a zip archive of the deploy folder, without configs or libraries. Don't forget to update Chat Overflow Framework and API Version before a public release.

## Create a new plugin project

Use the *Create Plugin* configuration or start the custom task `sbt create` directly. Enter the basic plugin information in the command promt. This includes the name, version and base plugin folder (e.g. `plugins-public`). The command creates the folder structure of the new plugin and adds a basic build file.

Here you can also add custom dependencies.

Next, run the custom task `sbt fetch` to let the framework look for new plugins and update the plugin reference file `plugins.sbt`. If you're using IntelliJ, you can now reload the framework by hand to register the plugin as new and custom project. You should also run `sbt reload` (Yes, both actions have different effects although they shouldn't).

## Implement the pluggable

Next, add your first class to the source folder of the new plugin. Supported languages are *Scala* and *Java*, but this guide will only show the scala way - development of java plugins is very similar.

The first class should extend the Pluggable-Interface from `org.codeoverflow.chatoverflow.api.plugin.Pluggable`. When the framework starts up, your plugin will be looked trough for a class implementing this interface to get an entry point to your work. A raw version might look like this:

**A short explanation**: The first 3 Methods `getName`, `getAuthor` and `getDescription` are simple: Just a return a String representing the meta information of your plugin. This inclucde it's name (please make sure to not name two plugins develeoped by yourself the same), your name or pseudonym and a brief topic of the plugins purpose.

The next two methods return the number of the API-Version, you developed the plugin with. These are evaluated in the loading process to ensure that your plugin works with the framework version from the user. You can get these numbers from `org.codeoverflow.chatoverflow.api.APIVersion`.

The last method `createNewPluginInstance` is the interesting one: After the framework checked your meta and version information, it will eventually load your plugin completely.

Let's talk about *Requirements* first: These are the way to retrieve data from the outside world and returning information to it. Basicaly, you can require everything from a single paramter, set by the user to full access to a users livestream chat.
Let's talk about *Requirements* first: These are used to retrieve data from the outside world and returning information to it. Basically, you can require everything from a single parameter set by the user to full access to a users livestream chat.

The `getRequirements` method is used by the framework to check what your plugin needs and to ask the user to specify which services or data he wants to give to your plugin. Here is a example:
The `getRequirements` method is used by the framework to check what your plugin needs and to ask the user to specify which services or data he wants to give to your plugin. Here is an example:

```
private val require = new Requirements
private val twitchChatInput = require.input.twitchChat("reqTwitch", "A twitch channel", false)
private val nameToSayHelloTo = require.parameter.string("reqHello", "Your name", false)
```

This code requires reading-access to a twitch livestream chat and a parameter ("*a name to say hello to"*). Note: You can obviously not specify, which channel the user might choose - but you can be sure, that you will get a working input. This is ensured by the framework. Please note, that the requirements element already exists, if you extend `PluginImpl`.

Please note that the requirements element already exists if you extend `PluginImpl`.

After this, the last step ist the `start` method. And it is as easy as you might think: Just add your own logic now, using the required parameters of your Requirement object. Here is a short example: This code will simply print out all messages from a twitch chat in the console. To access the chat, your required variable is used with the `getValue` method.

Of course, you can also add own classes and infrastrucutre by now - the important steps are done, happy coding!

*One last note: If your testing your plugin the first time, a full reload might be needed. Use the custom task `[Advanced] Full Reload and run ChatOverlfow` to do so. Afters this, you can configure the framework to start your plugin using the [CLI](usage/Using-the-CLI.md)!*
