Board Kata

A simple kata to emulate Twitter text transformation behaviour.

Exercise details

This excersise want to simulate the Twitter text transformation behaviour, it does it means that you'll recieve a csv file with multiples texts, you need to have in consideration that these texts could contains "," into them.

You need to create a parse function who is responsible of all transformations.

// Parse fomating the text into a valid output text
func Parse(msg string) (output string) {
	// code here
	return output
}

The rules of transformations are:

• Each url must be parsed into a html form -> https://friendsofgo.tech (<a href="https://friendsofgo.tech">https://friendsofgo.tech</a>)
• Each mention must be parsed into a author link -> @FriendsOfGoTech (<a href="https://fogo-parser.dev/FriendsOfGoTech">@FriendsOfGoTech</a>)
• Each hashtag must be parsed into a hashtag link -> #friendsofgo (<a href="https://fogo-parser.dev/hash/friendsofgo">#friendsofgo</a>)

Furthermore you'll have to detect on you can apply errors by behaviour and create the test for the package parser

Boilerplate

In this excersise we give you the csv reader that read the data/input.csv file and we give you the main.go and you need the complete with all necessary

func main() {
	msg, err := board.ReadInput("data/input.csv")
	if err != nil {
		log.Fatal(err)
	}

	// TODO: Parse each message
	fmt.Println(msg)

	//TODO: Print output into an html file

	fmt.Println("done!")
}

Run

First of all we use go modules for this boilerplate

$ go mod tidy

And then you can run your application

$ go run cmd/board/main.go

Bonus

• Use only errors by behaviour
• Use table driven tests
• Get >90% coverage into parser package
• Print output of all files into a html file
