Some background

Tabby 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 Node.js 14 or newer and Yarn.

First, install the dependencies:

# macOS:
yarn
./scripts/build-native.js

# Linux (Debian/Ubuntu here as an example)
sudo apt install libfontconfig-dev libsecret-1-dev libarchive-tools libnss3 libatk1.0-0 libatk-bridge2.0-0 libgdk-pixbuf2.0-0 libgtk-3-0 libgbm1 cmake
yarn
./scripts/build-native.js

# Windows:
npm -g install windows-build-tools
yarn
node scripts\build-native.js

Now, check if your build is working:

yarn run build

Start Tabby with

yarn start

Building an installer

To build an installer, first complete a "normal" build as described above and then run:

node scripts/prepackage-plugins.js

node scripts/build-windows.js
# or
node scripts/build-linux.js
# or
node scripts/build-macos.js

The artifacts will be produced in the dist folder.

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 TABBY_PLUGINS environment var.

Only modules whose package.json file contains a tabby-plugin keyword will be loaded.

If you're currently in your plugin's directory, start Tabby as TABBY_PLUGINS=$(pwd) tabby --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.

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:

import { NgModule, Injectable } from '@angular/core'
import { ToolbarButtonProvider, ToolbarButton } from 'tabby-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 tabby-core/src/api.ts, tabby-settings/src/api.ts, tabby-local/src/api.ts and tabby-terminal/src/api.ts for the available extension points.

Publish your plugin on NPM with a tabby-plugin keyword to make it appear in the Plugin Manager.
