Struct Config 

pub struct Config {
    pub auto_reload: bool,
    pub debounce_ms: u32,
    pub image_viewer: Option<String>,
    pub plot_viewer: Option<String>,
    pub show_timings: bool,
    pub clear_on_run: bool,
}

Configuration options for a cellbook.

Pass to the cellbook!() macro to customize behavior:

// Using struct literal
cellbook!(Config {
    auto_reload: false,
    ..Default::default()
});

// Using builder methods
cellbook!(Config::default()
    .auto_reload(false)
    .image_viewer("feh"));

// Using defaults
cellbook!();

Fields

auto_reload: bool

Watch for file changes and rebuild automatically. Default: true

debounce_ms: u32

Debounce delay for file watcher in milliseconds. Default: 500

image_viewer: Option<String>

External command to view images (e.g., “feh”, “open”, “xdg-open”). If None, uses platform default.

plot_viewer: Option<String>

External command to view plots. If None, uses image_viewer or platform default.

show_timings: bool

Show timing information for cell execution. Default: false

clear_on_run: bool

Clear output between cell runs. Default: false
