Few days ago I've created a script for the project I'm working on. It was an ugly script with hardcoded values, but it did ther job - create tokens on request. But I've decided to improve it a bit, because sometimes I needed to change params and I've added ability to submit params from the command line. Of course, there are a lot of awesome libraries such as dry-cli, TTY Toolkit or cli-kit from Shopify, but in most cases you can use standard ruby libraries like OptionParser or GetoptLong. Lets see how you can create a CLI utils with those libraries just in few minutes.
We will start with GetoptLong library.
Next stop - OptionParser. Similar with GetoptLong we create an instance of OptionParser class with list of available params. There are an opts.banner option which allow us to add some text before list of available params.
