Markdown

Markdown, is a plain text format that can be used to express stylized text. Often other programs or tools will render markdown as html (or even pdf). It is also commonly used in platforms, such as Github, to format issues, and homepages for repositories. You can mix and match html with markdown, but there are limits, as tags such as <script></script> are often stripped.

How about an example. The following markdown syntax, would appear as follows:

##### Example Header (like <h5>Header</h5>)

Paragraphs are separated by a blank line.  A hard break can be created by adding two spaces after a sentance.

2nd paragraph. *Italic*, **bold**, and `monospace` (inline code).

➡️ Renders as: ➡️

Lists, Blockquotes, Hrefs, and Images

You can do more advanced things, such as creating lists.

Itemized lists look like:

  * this one
  * that one
  * the other one

Hrefs have an anchor in brackets [] and (link in parens): See [Markdown format](https://daringfireball.net/projects/markdown/)

Code

You can also create code using "code fences".

```python
n = 50 # We want to find prime numbers between 2 and 50

print sorted(set(range(2,n+1)).difference(set((p * f) for p in range(2,int(n**0.5) + 2) for f in range(2,(n/p)+1))))
```

Tables

There are many different "flavors" of markdown. Github-flavored markdown supports "tables". Which can be nice to report data results:

| Parameters     | 5% tfidf scores - 34 nodes | 10 % tfidf score - 34 nodes | original result for 2 GB - 34 nodes |
| ------------- |:-------------:|:-------------:|:-------------:|

| Total Token size for training | 256469820 | 238648536 | 211167796 |

Markdown editors

Integrated development environments (IDEs)

If you're still opening and editing files in Notepad.exe, let's show you a better way!

IDEs are an important part of a professional programming environment. You can perform many tasks such as editing, refactoring, compiling, testing, and debugging. IDEs also usually support an extensive set of plugins that help you integrate with other tools, such as maven, or performing style checking of your code.

Lightweight IDEs/editors

While traditional IDEs such as Visual Studio or Eclipse are industry standards, that's not the only option out there!

If you need to quickly edit code scripts, html, or markdown, features such as syntax highlighting, autocomplete, and advanced find and replace tools are essential! However, you may not want to fire up Eclipse to change just one character. Here are some alternative IDEs to consider.

  • Code
  • Atom
  • Level up vim: Put some of these stuff in your vimrc.
  • ... Missing something? Send a pull request.

Exercise: Install VSCode!

choco install vscode -y

brew install visual-studio-code

Practice: Create an About Me Page

Update your README.md in 'Basics/' in your favorite editor. Using your new markdown skills, include the following details:

  • Something about you.
  • Where you are from.
  • A picture.
  • A list of skills
  • If brave, a table and a favorite code snippet.

Commit and push the code to your remote repository.

Advanced: Creating a WebPage using GitHub Pages

You can use GitHub Pages to host static (generated) web content. A typical pattern is to keep your source materials (markdown/templates) on your master branch, while keeping your generated content (html/js/css) on a gh-pages branch.

Let's practice creating a hosted version of your site. Bonus: It is also great practice of your git knowledge.

Pandoc

First, let's download a simple tool that can help us translate markdown => html. Using a package manager, download pandoc. e.g. for Windows, choco install pandoc.

Test out using pandoc on your README.md

pandoc README.md

You should see html output on the console. Before we try keeping this content, let's prepare our gh-pages branch.

Creating gh-pages

You can create a new branch using git branch gh-pages. Do you remember which command we should use to switch branches?

Use git switch gh-pages. You should see that you have switched to the gh-pages branch. Confirm with git branch. You should see an asterisk next to gh-pages.

Using the stdout redirect operator >, you should be able to run pandoc again, but write to a new file index.html. Stage and commit the new file.

Let's get dangerous. Remember, we do not want source content in our gh-pages, so that means you can delete your README.md when you are in the gh-pages branch.

Push your changes.

Viewing GitHub Pages

You should now be able to see your html file on GitHub!

For GitHub, your page will be available at the following url:

http://<user>.github.io/<repo>/index.html

For example, see:

For GitHub Enterprise, your page will be available at the following url:

http://pages.github.ncsu.edu/<user>/<repo>/index.html
