* Assignment 1

/... to shave a yak/

* Goal

Submit coursework in a way that:

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

We will not be using MyPlace, we will use the department Gitlab server
instead.
   
* 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 [[https://github.com/][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/

1. Create a repository
2. Create an access token (note it down, you will need it)    
3. Share it with me (xgb21195) as "reviewer"

* Sharing your repository (2)

Join the hosted repository to your local one

#+begin_src
git remote add gitlab
     https://oauth2:XXXX@gitlab.cis.strath.ac.uk/...
#+end_src

Push your work to the hosted repository

#+begin_src
git push -u gitlab
#+end_src

* 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

1. Open =emacs=
2. 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.
