In this repo you will find the step-by-step, test-driven development of the runes example: a command-line utility to find Unicode characters by name.

Each step in the development is documented explaining the Go language features used in the code.

Only a very basic knowdledge of Go is required to follow.

By the end of this tutorial, we'll have a command-line utility which works like this:

$ runes face eyes
U+1F601	😁	GRINNING FACE WITH SMILING EYES
U+1F604	😄	SMILING FACE WITH OPEN MOUTH AND SMILING EYES
U+1F606	😆	SMILING FACE WITH OPEN MOUTH AND TIGHTLY-CLOSED EYES
U+1F60A	😊	SMILING FACE WITH SMILING EYES
U+1F60D	😍	SMILING FACE WITH HEART-SHAPED EYES
U+1F619	😙	KISSING FACE WITH SMILING EYES
U+1F61A	😚	KISSING FACE WITH CLOSED EYES
U+1F61D	😝	FACE WITH STUCK-OUT TONGUE AND TIGHTLY-CLOSED EYES
U+1F638	😸	GRINNING CAT FACE WITH SMILING EYES
U+1F63B	😻	SMILING CAT FACE WITH HEART-SHAPED EYES
U+1F63D	😽	KISSING CAT FACE WITH CLOSED EYES
U+1F644	🙄	FACE WITH ROLLING EYES

You give runes one or more words as arguments, and it displays a list of Unicode characters whose names contains all the words you provided.

This tutorial is based in the charfinder example from chapter 18 of Fluent Python, by Luciano Ramalho. The Go version named runefinder, was started in the Garoa Gophers, study group by Afonso Coutinho (@afonso), Alexandre Souza (@alexandre), Andrews Medina (@andrewsmedina), João "JC" Martins (@jcmartins), Luciano Ramalho (@ramalho), Marcio Ribeiro (@mmr), and Michael Howard.
