About this website
How to use/edit this site
This is a static website automatically generated with Jekyll by GitHub Pages. The source code is available on GitHub and you are allowed to use it under the terms of the Creative Commons BY-NC-SA 4.0.
You are a teacher, a student, or a casual visitor and want to learn how to improve this site, this help page is for you!
You can edit any page by clicking on the Edit link in the top menu.
This will drop you in GitHub’s file editing interface, where you can modify the source code, preview it, and save your changes, by giving a short description of what you modified. If you are a collaborator to this website, and have write access to the GitHub repository, your modifications will be published rightaway. If you do not have right access, you will be asked to fork the repository and make a pull request. See also the next section.
CAVEATS: The Markdown engine used by this site is Kramdown. Its syntax definitions are slightly different form GitHub Flavored Markdown, thus the preview feature in GitHub might not render source as in the final result.
Other reasons why GitHub’s preview may not correspond to the final results are:
- Use of Liquid templates in the source. This is seldom used, but some pages (like this one) use them to access site-wide configuration variables.
- Use of special purpose markup, HTML, and scripts, such as mathematical excerpts written in MathJax.
Forking the website for your own use
You want to get a copy of the website and its source code to analyze it, or make your own derivative of it, this is very easily done, even if you’re not (yet!) the technical type.
Now you can make changes to your own copy of the site. Edit some files, save the changes, and examine the result. The compiled static site will be served at http://username.github.io/lmdsio-si1.github.io (replace username by your GitHub user name).
Note: the website will not be compiled when you first fork the repository. If you want your fork to be served on github.io before committing any changes, you will have to create a local clone of your fork, then push. This will not create any new commit, but will force GitHub to compile your copy of the site. In a Unix shell, this is
git clone firstname.lastname@example.org:username/lmdsio-si1.github.io.git cd lmdsio-si1.github.io git push
Contributing your changes back to this site
You have forked the repository, made your changes, and now want to contribute them back to the site, but you do not have write access.
Pull requests are GitHub’s standard way of contributing changes back to the original repository. You can make a pull request for this repository, your changes will be reviewed and integrated back once they are accepted.
You want to do more than the occasional editing, or you want to deeply modify the code to make your own site. GitHub’s editor and preview are too limited for this, and handling git history via GitHub’s web interface becomes too clumsy at this point. You need to work locally on your computer.
At some point, you will need to preview your work, but pushing to GitHub each time you want to preview is clumsy. Your best option is to install Jekyll and the required dependencies on your machine. It is recommended to install the GitHub pages gem which provides you with the exact same versions used by GitHub to compile your site.
If you already have Ruby
install part should be as easy as
gem install github-pages
Note that you will need Ruby headers (
ruby-dev package on Ubuntu) in
order to compile C dependencies.
Now you can
cd into your local clone of the repository and launch
the compilation by
jekyll serve -w -b''
Your site will be generated in a
_site sub-directory, and served
live at http://localhost:4000/. Any changes to the sources will
trigger an automatic recompilation!
Have fun coding!
Note: you will notice that the source for the site is in a branch
gh-pages. If you are familiar with Git, this
will surprise you as the usual branch name for Git repositories is
master. This special name is where all the GitHub pages magic comes
from: name your branch
gh-pages, and GitHub will automatically
compile it when you push.
Starting from scratch
This website was created from an empty template ate https://github.com/defeo/class-boilerplate/. You can start from there if you want to create a website for your own class.
