Ocawari

Fetches the images from supported domains, primarily where images of Japanese idols can be found such as Twitter or Instagram and less commonly social media sites like 755 and Google Plus. Since this was developed for personal scripting use, features are added sporadically and may not be suitable for production.

Requirements

Ruby 2.5 or higher

Installation

Add this line to your application's Gemfile:

gem 'ocawari'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ocawari

Usage

Ocawari accepts either an array of urls or a string through a public #parse class method through the top level Ocawari module. The #parse method can take either an array of urls or a single string. In the case that it receives no valid arguments (empty Array, empty String, nil, invalid string url, failed network requests), it will return an empty Array.

require "ocawari"

# With url as argument
urls = [
  "https://twitter.com/kayoyon213/status/853480124875919360",

Ocawari.parse(urls)

Ocawari also comes with a command line interface via the oca command. It takes any number of arguments and then outputs the urls to the images to STDOUT.

By doing this, I am usually running the following commands or something similar at least several times a days
