# Comprehensive Rust 🦀 Style Guide
The course has been expanded and improved by tons of volunteers like you! Thank
you for that! To help ensure a consistent style throughout the course, we have
written down some guidelines for you to follow.
## Course Slides
Please take the following into account when updating the course material.
### Vertical Space
What looks like pages in a browser, are actually slides in a presentation. It is
important to keep this in mind when adding content: we only have limited
vertical space. Scrolling up and down should be avoided since it is very jarring
for people who attend the class.
You can test the amount of space available using a simple tool. This tool can be
used by clicking a toggle button next to the search button on left side of the
navbar.
The rectangle has an aspect ratio similar to what you can see when you share
your screen on a 16:9 display or projector.
Use the rectangle as a rough guide for how much you can fit on a single slide.
If you find yourself adding too much detail, move the details to the speaker
notes (see below).
### Rust Code
When showing Rust code, please use the same spacing as `rustfmt`: `3 * x`
instead of `3*x`. However, feel free to remove newlines when it can make the
code more compact and easier to understand, e.g., you can use
<!-- dprint-ignore-start -->
```rust
struct Person { name: String }
```
<!-- dprint-ignore-end -->
if the `Person` struct is not important for your example. Please use this
sparingly: enclose the code block in `<!-- dprint-ignore-start -->` and
`<!-- dprint-ignore-end -->` to suppress warnings about the formatting.
## Speaker Notes
We have extended `mdbook` with support for speaker notes: content added between
`<details> ... </details>` tags is rendered in a special box that can be
collapsed or removed entirely from the slide.
- The speaker notes should expand on the topic of the slide. Use them to provide
interesting background information for both the instructor and for students
who look at the material outside of a class. Remember that many more people
will read the course by themselves, so make the notes complete and useful even
when there is no Rust expert around.
- Avoid using speaker notes as a script for the instructor. When teaching the
course, instructors will only have time to glance at the notes so it is not
useful to include full paragraphs which the instructor should read out loud.
### More to Explore
Move extended explanations in the notes to a "More to Explore" section:
```markdown
<details>
...
## More to Explore
...
</details>
```
The material there is outside the scope of the regular class.
## Translations
This section is about what you write in the translation. We describe
[how to create or update translations elsewhere](TRANSLATIONS.md).
When translating the course, please take the following into account:
- Do not translate:
- The course name ("Comprehensive Rust 🦀"). If the name is not easily
understood in your language, please add the translated version after the
original name.
- Variable names (you _should_ translate the comments, though.)
- If the Rust Book has been
[translated into your language](https://doc.rust-lang.org/book/appendix-06-translation.html),
please use the same vocabulary.
- The text you write is in Markdown format. Make sure to preserve the original
formatting in the translation by marking text as `` `code` ``, `_emphasis_`
and `**strong emphasis**` like in the original.
- If you find mistakes or things that sound awkward in the original English
text, please submit PRs to fix them! Fixing typos in the translation is great,
but we want everybody to benefit from the fixes and that is why we need the
fix to be made in the English text too.
