<div class="content"><h1>Teacher Notes</h1>
<h2>Slides</h2>
<p>Some slides are in test-first-teaching/ruby_notes. They're in Markdown+Showoff format, which means they should be usable either as slides</p>
<pre><code>cd ruby_notes
showoff ruby_notes
</code></pre>
<p>or plain HTML</p>
<pre><code>cd ruby_notes
rdiscount *.md > index.html
</code></pre>
<h2>Rules (for students)</h2>
<ul>
<li>Always read the error!</li>
</ul>
<h2>Solutions</h2>
<p>The <code>solutions</code> branch is dead; long live the <code>solution</code> directory.</p>
<p>To add a solution, you must put your Ruby file(s) in a directory <strong>inside</strong> the lab directory with the name <code>solution</code>, e.g. <code>learn_ruby/hello/solution/hello.rb</code>.</p>
<p>Solutions only appear in the teacher repository (<code>test-first-teaching</code>) not the generated student repo (<code>learn_ruby</code>). When you run <code>rake</code> the tests will be run against the solutions, to assure that your code is correct.</p>
<p>Make sure not to check in any cruft in the lab directory, since that will be seen by (and surely befuddle) students.</p>
<p>Multiple solutions aren't supported yet.</p>
<h2>Notes and instructions</h2>
<p>Every lab has (or can have) a <code>index.md</code> file that the students can read. This is a good place for background, instructions and hints for solving the exercises.</p>
<p>Files ending with <code>.md</code> (Markdown) are converted to HTML and given a <code>.html</code> suffix, and files ending with <code>.scss</code> (Sass/SCSS) are converted to CSS and given a <code>.css</code> suffix. Any other files will be copied over to the student repo as is.</p>
<p>Lab directories become numbered; e.g. <code>hello</code> will become <code>00_hello</code>.</p>
<p>Each curriculum contains an <code>assets</code> directory, which is a good place to put shared files like <code>.js</code> and <code>.css</code> and images. You can refer to them using <code>..</code> in your markdown files, e.g.</p>
<pre><code>
</code></pre>
<p>This works in "preview mode" too, though it's a little weird, since <code>.scss</code> isn't converted into <code>.css</code> until the course is built using <code>rake build</code>.</p>
<p>There's also a <code>ubiquitous</code> directory, whose contents are copied into each and every generated lab directory.</p>
<h2>Tricks</h2>
<p>Here are some nice git config settings:</p>
<pre><code>git config --global alias.st status
git config --global alias.ci commit
git config --global alias.co checkout
git config --global alias.br branch
git config --global alias.unadd "reset HEAD"
git config --global alias.l "log --oneline --decorate --graph"
git config --global push.default matching
git config --global color.branch=auto
git config --global color.diff=auto
git config --global color.interactive=auto
git config --global color.status=auto
</code></pre>
<p>Or, you can edit <code>$HOME/.gitconfig</code> -- you should have sections like this:</p>
<pre><code>[color]
branch = auto
diff = auto
interactive = auto
status = auto
[alias]
st = status
ci = commit
co = checkout
br = branch
unadd = reset HEAD
l = log --oneline --decorate --graph
[push]
default = matching
</code></pre>
