Git

The easy way

Use Gitlab's WebIDE. You won't be able to 100% accurately preview the result until you commit and the servers are updated.

The powerful way

Run the website locally and preview your changes instantly. Head over to the sources of the server instance to learn how to set it up.

File Structure

Each page is a directory.

File names

We define as slug-case what some call kebab-case.

• lowercase
• alphanumeric
• joined with -
• a-z, no diacritics
• starts with a letter (probably best)

Directories

[<NN>.]<slug>

The numbers prefix can be ignored when building links, its purpose is to order sibling pages.

Set the english slug ; localized slugs can be set in frontmatters like so:

title: Joyeux Noël!
slug: joyeux-noel

Markdown files

<template>[.<lang>].md

The name of the file will define the template of the page, that is how the content will appear.

For example, the template columns will display the children of the page as columns.

The available templates are :

• default
• portal
• topics
• topic
• columns
• textbook
• cheatsheet
• annex

Right now there are not many differences between the various templates but there may be later.

Other files

• Use slug-case with the occasional snake between slugs.
• Be expressive. This is an exercise in aphorisms. fig-a_rays-through-convex-lens.png
• use a ISO 639-1 code as suffix like an extension like so: textbook.fr.md.

LateX

You can use LateX in the courses :

$`E = m \cdot c^2`$

yields $E = m \cdot c^2$

You can omit the backticks (`) but the preview in gitlab won't work.

Mermaid

You can display flowcharts in the courses :

``` mermaid
graph LR
    subgraph Course
        File[File]
    end

    Student((Student))

    Student --> |reads| File
```

yields

graph LR
  subgraph Course
    File[File]
  end

  Student((Student))

  Student --> |reads| File

LR is for Left to Right. You could use TB for Top to Bottom.

GANTT diagrams and sequence diagrams are also available. Read on mermaid's documentation for more information.
