# Some background
Terminus is an Electron app, with the frontend written in Typescript with the help of Angular framework. It's built using Webpack.
# Getting started
First of all, clone this repository. You'll also need a recent version of Node installed.
First, install the dependencies:
```
# macOS/Linux:
npm install
./scripts/install-deps.js
./scripts/build-native.js
# Windows:
npm -g install windows-build-tools
npm install
node scripts\install-deps.js
node scripts\build-native.js
```
Now, check if your build is working:
```
npm run build
```
Start Terminus with
```
npm start
```

# Plugins
The app will load all plugins from the source checkout in the dev mode, from the user's plugins directory at all times (click `Open Plugins Directory` under `Settings` > `Plugins`) and from the directory specified by the `TERMINUS_PLUGINS` environment var.
Only modules whose `package.json` file contains a `terminus-plugin` keyword will be loaded.
If you're currently in your plugin's directory, start Terminus as `TERMINUS_PLUGINS=$(pwd) terminus --debug`
A plugin should only provide a default export, which should be a `NgModule` class (or a `NgModuleWithDependencies` where applicable). This module will be injected as a dependency to the app's root module.
```javascript
import { NgModule } from '@angular/core'
@NgModule()
export default class MyModule {
constructor () {
console.log('Angular engaged, cap\'n.')
}
}
```
Plugins provide functionality by exporting singular or multi providers:
```javascript
import { NgModule, Injectable } from '@angular/core'
import { ToolbarButtonProvider, ToolbarButton } from 'terminus-core'
@Injectable()
export class MyButtonProvider extends ToolbarButtonProvider {
provide (): ToolbarButton[] {
return [{
icon: 'star',
title: 'Foobar',
weight: 10,
click: () => {
alert('Woohoo!')
}
}]
}
}
@NgModule({
providers: [
{ provide: ToolbarButtonProvider, useClass: MyButtonProvider, multi: true },
],
})
export default class MyModule { }
```
See `terminus-core/src/api.ts`, `terminus-settings/src/api.ts` and `terminus-terminal/src/api.ts` for the available extension points.
Publish your plugin on NPM with a `terminus-plugin` keyword to make it appear in the Plugin Manager.
