Code styling

This presentation shows how to:

  • Left-align code blocks.
  • Have code blocks without background.
  • Execute code snippets.
rust
pub struct Greeter {
    prefix: &'static str,
}

impl Greeter {
    /// Greet someone.
    pub fn greet(&self, name: &str) -> String {
        let prefix = self.prefix;
        format!("{prefix} {name}!")
    }
}

fn main() {
    let greeter = Greeter { prefix: "Oh, hi" };
    let greeting = greeter.greet("Mark");
    println!("{greeting}");
}
<!-- end_slide -->

Column layouts

The same code as the one before but split into two columns to split the API definition with its usage:

<!-- column_layout: [1, 1] --> <!-- column: 0 -->

The Greeter type

rust
pub struct Greeter {
    prefix: &'static str,
}

impl Greeter {
    /// Greet someone.
    pub fn greet(&self, name: &str) -> String {
        let prefix = self.prefix;
        format!("{prefix} {name}!")
    }
}
<!-- column: 1 -->

Using the Greeter

rust
fn main() {
    let greeter = Greeter {
      prefix: "Oh, hi"
    };
    let greeting = greeter.greet("Mark");
    println!("{greeting}");
}
<!-- end_slide -->

Snippet execution

Run code snippets from the presentation and display their output dynamically.

python
/// import time
for i in range(0, 5):
    print(f"count is {i}")
    time.sleep(0.5)
<!-- end_slide -->

Snippet execution - stderr

Output from stderr will also be shown as output.

bash
echo "This is a successful command"
sleep 0.5
echo "This message redirects to stderr" >&2
sleep 0.5
echo "This is a successful command again"
sleep 0.5
