gobook's Introduction

"Learning Go" is now available online.

See https://miek.nl/go and this github repo.

Note this book's source has been rewritten in mmark and that source is available at https://github.com/miekg/learninggo.

THIS REPO IS DEPRECATED.

`Learning Go` - a free PDF for learning the Go language.

The book currently consists of the following chapters:

Introduction: Details the lineage of the language Go and shows the types, variables and control structures.
Functions: How to make and use functions.
Packages: Functions and data are grouped together in packages. Here you will see how to make your own package. How to unit test your package is also described.
Beyond the basics: Learn how to create your own data types and define functions on them (called methods in Go).
Interfaces: Go does not support Object Orientation in the traditional sense. In Go the central concept is interfaces.
Concurrency: With the go keyword functions can be started in separate routines (called goroutines). Communication with these goroutines is done via channels.
Communication : How to create/read/write from and to files. And how to do networking.

Each chapter concludes with a number of exercises with answers to help you get some hands-on experience. Currently there are more than 30 exercises.

See http://www.golang.org for the homepage of Go.

gobook's Issues

Converted Kindle tex is overlapping

The first line on each content page is overriding the heading. I tried to fix this but I do not know Latex.
And Kindle is arranged in portrait by default.

Site for the book gives 404s

In the README file all the links to the project page, and page to download the latest PDF gives 404 errors.

ePub / Mobi version

Hello,

is there a way to compile this with a mobi for kindle target?

Answer for Chapter 1 Q4-3

Exercise: "Extend the program from the previous question to replace the three runes at po- sition 4 with ’abc’."

How about this:

package main

import "fmt"

func main() {
  s := "asSASA ddd dsjkdsjs dk";

  // convert to array of runes
  chars := []rune(s)

  // allocate space for the head
  head := make([]rune, 3)

  // grab the head and store
  copy(head, chars[0:3]);

  // generate our new substring
  middle := []rune("abc");

  // make a new head: which is original head plus our new substring
  head = append(head, middle...);

  // grab the rest of the string
  tail := chars[4:]

  // combine our new head with the rest of the string
  combined := append(head, tail...);

  fmt.Printf("Initial: %s\n", s);
  fmt.Printf("Final: %s\n", string(combined))
}

About Leaning Go PDF deployment

Thanks for your Learning Go book 👍

To make it easy to find the lastest version, it would be better to create symbolic link to 20130612-go.pdf.

$ ln -s 20130612-go.pdf learning-go-lastest.pdf

What do you think about?

Package xkeyval Error: `Path' undefined in families `options'.

When trying to build the book following the instructions in the readme I get the above error. I had first run the package-install script as suggested. I have posted the full terminal output in this gist.

Godoc v. go doc in Go 1.14

I am a novice at Go, so this might have an obvious reason/solution, however I have run into a problem on the first page of the book. It says to use godoc hash to read about the hash package. I tried that and it says this:

Unexpected arguments. Use "go doc" for command-line help output instead. For example, "go doc fmt.Printf".
usage: godoc -http=localhost:6060

When using go doc hash, everything works as expected. Should go doc hash be the recommended command to run instead?

I am not sure why the difference in Godoc and go doc. I installed godoc using go get golang.org/x/tools/cmd/godoc which is a command I just got somewhere, I didn't find any "official" way to do it and the highest ranked Google result (some reddit post) contained a command which didn't work for me (it hung). So I settled at this command.

I am using Go 1.14 so it's possible things have changed between when this (and others books and resources I've been using) were written and today.

"Object Orientation in the traditional sense"

This struck me as weird. Object orientation does not require inheritance. Go has objects which interact over clearly defined interfaces and hence is object oriented. I feel like saying it's not really object-oriented gives the wrong message and throws a bad light on an actually very nice language design.

The lack of inheritance is a "feature" i regularly point out to people new to go - as a good thing.
