SCION tutorials page

The website is deployed on Github Pages.

About

SCION tutorial pages are written in markdown and they are placed in the content directory. The HTML website is generated using MkDocs.

The generated HTML website is placed in the docs directory.

Building pages

In order to build the website you will need to install MkDocs. Also, the pygments package should be installed to enable syntax highlighting of code snippets in the tutorials. Note that different versions of mkdocs can generating rather different output. To avoid this issue, prefer to use a virtual python environment and use the requirements.txt file to install the exact versions of the python packages.

virtualenv -p /usr/bin/python2.7 venv
source venv/bin/activate
pip install -r requirements.txt

In order to generate the website just run in the activated virtualenv:

mkdocs build

The newly generated website will be placed in the docs directory.

During the development phase, it is possible to run a local webserver and automatically refresh the website content. To do this, run:

mkdocs serve

Adding new page

Adding a new page consists of 2 steps:

1. Add a new markdown file in the content directory with the page's content
2. Add page information into the corresponding category with description in mkdocs.yml (at the end of the file)

mkdocs-material customisation

The mkdocs-material theme is used for the SCION tutorials page. To change the color palette used in this theme, the source code has to be edited (squidfunk/mkdocs-material#874).

Therefore the mkdocs-material source code was added as a git subtree, so we can add commits on top:

$ git subtree add -P mkdocs-material --squash https://github.com/squidfunk/mkdocs-material.git 3.0.4

Currently, the following customisations have been applied to the theme:

• Change primary/accent colors
• Set favicon
• Set font size and margin for title in navigation-panel
• Remove next/previous navigation links in footer

Using git subtree will (hopefully) allow to update to newer versions of mkdocs-material if necessary, by running e.g.

$ git subtree pull -P mkdocs-material --squash https://github.com/squidfunk/mkdocs-material.git <tag>

After updating the mkdocs-material version and re-applying the customisations, the theme has to be rebuilt; you'll need nodejs>=8 and npm installed, then simply run make and check in the rebuilt mkdocs-material/material folder.

Check links

You can always look for broken links in the tutorials by running:

wget --spider -r -nd -nv -l 3 -w 0 -o - https://netsec-ethz.github.io/scion-tutorials/ | grep -B1 'broken link!'

Prior to merge to master it is always nice to check against our own repository. For that you need to enable Github Pages in your clone of scion-tutorials, and remembering that Github Pages are available only for the master branch, your commits would have to be pushed to your master. E.g.:

git push myremotename HEAD:master
sleep 30
wget --spider -r -nd -nv -l 3 -w 0 -o - https://mygithubusername.github.io/scion-tutorials/ | grep -B1 'broken link!'
