Introduction to GO CS240 20/8/2017 1
Course overview ● Course website: http://web.kaust.edu.sa/Faculty/MarcoCanini/classes/CS240/F17/ ● Piazza: https://piazza.com/kaust.edu.sa/fall2017/cs240/home ● Grades are based on lab assignments and exams ● We will use Go as the programming language for the assignments ● Prof. Canini is away this week; he will expand more on the class overview next week ● Today we will re-introduce version control and go over the basics of Go (golang) 2
Version control It is a way to manage different versions or revisions of the files. Examples: ● Undo/redo buffers ● Google docs ● Overleaf (online Latex) ● Multiple versions sibyani@kaust:~$ ls assignment1-1.go assignment1-2.go assignment1-3_work_in_progress.go 3
Example: finished 1-1 finished 1-2 working 1-3 sibyani assignment1.go assignment1.go assignment1.go 4 Local Versioning
finished 1-1 sibyani assignment1.go github/sibyani Remote Versioning 5
finished 1-1 sibyani assignment1.go finished 1-1 github/hsibyani assignment1.go Remote Versioning 6

Git ● Git is a version control system (not the only one) ● Most common commands ○ git init : create git repository ○ git add : add a file to be tracked in the repository https://education.github.com/pack ○ git commit : commit the current tracked files ○ git push : push the local files to the cloud ○ git pull : pull the cloud files locally ● Start with git at: https://try.github.io 11
Why Go? ● Simpler, cleaner, and faster programming ● Fast compilation ● Easier interface abstractions ● Garbage collection ● Concurrency as a goal ● Read more in: https://golang.org/doc/faq#Origins source: xkcd 12
Who uses Go? and many more ... 13
Installation ● Usually straightforward (package manager or source) ◦ apt (Ubuntu) ◦ yum / dnf (RedHat) ◦ brew (macOS) ● Pay special attention to environment variables ● You may need to make sure you configure some of them ( GOPATH and GOROOT ) 14
Demo: Basics and declarations 15
Demo: Packages 16
Demo: Control flow 17
Demo: Extras 18
To do before next class Join Piazza Install Go Go tour – up to the concurrency: https://tour.golang.org Do some exercises And if you have time: • How to write Go code: https://golang.org/doc/code.html • Effective Go: https://golang.org/doc/effective_go.html 19
