#backtick #bytes #multiline #printf #quotes #raw #string

This is an especially useful technique when working with large strings like SQL, HTML or XML within Go. Instead of using either the double quote (“) or single quote symbols (‘), instead use back-ticks to define the start and end of the string. You can then wrap it across lines. If you indent the string though, remember that the white space will count.

package main

import "fmt"

func main() {

	message := `This is a 
Multi-line Text String
Because it uses the raw-string back ticks 
instead of quotes.
`

	fmt.Printf("%s", message)
}

Perform Sentiment Analysis on Sentences – Jan 11, 2020
Sentiment analysis is an interesting technique of judging whether a sentence, word or paragraph is considered a positive or negative thing. It’s often used against datasets like tweets as it allows you to summarize a mass of small sentences into an easy to understand stat. In our example, we’re using a package called sentiment - which was trained against IMDB comment data - to judge whether our example sentences are positive or negative.
Convert iota List to String in JSON – Sep 29, 2019
Constants in Go, when combined with iota, can be a nice way to use options and settings as a list. We have an example below using genders to show this in action. The problem comes if you want to encode/decode structs to JSON, then the constant will be encoded into an int - sometimes it would be nice to convert this to a string to make it easier to represent what it is.
Read a File to String – Aug 8, 2019
This is a matching post to “Writing to a File” and explains how to simply get the contents of a file as text and print it to screen. There are different ways to achieve this in Go - all valid. In this guide though we’ve gone for the simple approach. Using ioutil makes this easy for us by not having to worry about closing files or using buffers. At the cost though of not having flexibility over which parts of the file we need.
