Assignment 1
… to shave a yak
Goal
Submit coursework in a way that:

  Has something to do with software development practice
  Makes it possible to automate marking

Git…

  is a “distributed version control system”
  started as a tool for coordinating the Linux kernel development
  keeps your files and their change history

  has a terrible user interface but is ubiquitous

Git repositories
A repository is a collection of changes to files.
You create a repository on your computer.
You keep a copy of the repository on a hosting service.
A popular hosting service is Github (Microsoft).
For this course, will use the department’s service,
  https://gitlab.cis.strath.ac.uk/
Push, pull and clone
The word for “making a copy of a repository” is “clone”.
To send changes from your computer to a remote repository, you “push”
  them.
To get changes from a remote repository to your computer, you “pull”
  them.
More yak shaving
Command line terminals

  Prompt, command, output
  Sort of an antique chatbot that doesn’t even bother to try to speak
    English!
  Somewhat cryptic commands…

Command line basics

  pwd
where am I? (what directory)
  hostname
where am I? (which computer)
  ls
list files
  cd
change directory
  mkdir
make directory
  cat
show what is in a file
  git
the git tool
  ssh
get a terminal on a different computer

Yet more yak shaving
Text editors

  pico / nano (easy, terminal)
  
mousepad, gedit, kate (easy, graphical)
  emacs, vi / vim (not easy)
  Notepad (on Windows)
  TextEdit (on MacOS)
  Many more, pluma, xed, Visual Studio Code, Atom, Pulsar, Spyder, Sublime Text,
    Notepad++, CudaText, Textadept…

Putting it together

  make a directory
mkdir cs101-coursework
  change to it
cd cs101-coursework
  make it a git repo
git init .
  create / edit a file
$EDITOR assignment-1.txt
  add that file to git
git add assignment-1.txt
  commit the changes
=git commit -m “first assignment”=

Now you have a git repository with one file in it on your computer.
Sharing your repository (1)
Go to https://gitlab.cis.strath.ac.uk/
web browser interlude

  Create a repository
  Create an access token (note it down, you will need it)
  Share it with me (xgb21195) as “reviewer”

Sharing your repository (2)
Join the hosted repository to your local one
git remote add gitlab
     https://oauth2:XXXX@gitlab.cis.strath.ac.uk/...

Push your work to the hosted repository
git push -u gitlab

Sharing your repository (3)
Now you have a git repository with a file in it, and a copy on the CIS
  gitlab server.
But I still do not know where it is! So I wrote a little program for
  you to tell me. Run the program,
/home/xgb21195/bin/cs101 https://gitlab.cis.strath.ac.uk/...
Finished yak shaving!
A classic psychotherapist chatbot
A clone of Joseph Weizenbaum’s ELIZA chatbot from the late 1960s

  Open emacs

  Type M-x doctor


(M-x means “meta-x”. The “meta” key is ESC or Alt)
You can save a session to a file with C-x C-s, control-x and then
  control-s. Using this file for assignment 1 will get top marks.
