When I wanted to search in English on Google, I used bookmarks to access it, but I thought it would be convenient to do it with a plugin, so I created one.

This plugin might be somewhat useful for niche users who hide the default bookmarks and use a plugin called Bookolio (which makes bookmarks easier to see) ← me.

Environment

• Google Chrome
• JavaScript

Specifications

There are various types of plugins, but what I am creating this time is this:

When you click the plugin icon, it simply opens the English version of Google in a new tab.

Since it's super simple, there is room for improvement in the specifications. ()

Preparation

First, create the folder and files.

└── search_by_english
    ├── background.js
    ├── icons
    │   ├── icon128.png
    │   ├── icon16.png
    │   └── icon48.png
    └── manifest.json

Please prepare the icons as needed.

The background.js is the JavaScript that runs in the background. For more details, please refer to the Developer's Guide.

Edit manifest.json

manifest.json

{
  "name": "Open A Google English Edition In A New Tab",
  "version": "1.0",
  "manifest_version": 2,
  "description": "Open a Google English Edition in a new tab.",
  "icons": {
    "16": "icons/icon16.png",
    "48": "icons/icon48.png",
    "128": "icons/icon128.png"
  },
  "browser_action": {
      "default_icon": "icons/icon48.png"
  },
  "background": {
    "scripts": [
      "background.js"
    ]
  }
}

The description varies depending on the type of plugin. It's not particularly difficult, so for details, please refer to the Developer's Guide.

Edit background.js

background.js

I referred to the code from Chrome extension: open link in new tab?. You should get a general idea by looking at it.

For more details, please refer to the documentation (ry) Developer's Guide.

chrome.browserAction.onClicked.addListener(function(activeTab){
  var newURL = "https://www.google.co.jp/?hl=en&gws_rd=cr&ei=O2OgV4jODcS30gSs1Ihw";
  chrome.tabs.create({ url: newURL });
});

Basically, you write in JavaScript, but you will be utilizing the API provided by Google regarding browser operations.

Thoughts

I would also like to try developing plugins for Atom.
