Go Price Parser

Don't you find it frustrating that whenever you are trying to parse price from scraped data, you can never just use one simple regex and be done with it?

Wouldn't be great, right?

Every website (and country) deciding to now use a comma, now a dot, and why not a space?!

Well, I was fed up with it and made this little library that just does one thing: you feed it a string with a price, and it gives you back a nicely formatted int.

Why an int, you might wonder?

Well, that's easy to deal with and not get crazy with all those float shenanigans.

Features 🚀

Parses a "dirty" price string into an integer (e.g. "42,069.23 USD" => 4206923)
Returns values as either directly integer or as Price struct (allows some extra formatting features)

Installation 📦

Install it as usual with:

  go get github.com/alexferrari88/go-price-parser

Usage/Examples 🔧

You can have the return values as either int or as the Price struct defined in this library

Return value as int

This is handy if you want to pipe the parsed price in a library such as Money.

scrapedPrice := "42.99 USD"
price, err := priceParser.IntFromString(scrapedPrice)
if err != nill {
    panic(err)
}

fmt.Println(price) // Output: 4299

Return value as Price struct

You can use this if you want to keep the currency or for some formatting (see below).

scrapedPrice := "42.99 USD"
price, err := priceParser.PriceFromString(scrapedPrice)
if err != nill {
    panic(err)
}

fmt.Println(price.Amount) // Output: 4299

Other handy functions in the package

If you keep the result of the function as Price struct, you can also use the functions String() and Float().

Examples

scrapedPrice := "42.99 USD"
price, err := priceParser.PriceFromString(scrapedPrice)
if err != nill {
    panic(err)
}

fmt.Println(price.Amount.String()) // Output: "42.99 USD"
fmt.Println(price.Amount.Float()) // Output: "42.99"
