Struct AppOptions 

pub struct AppOptions {
    pub left_dir: PathBuf,
    pub right_dir: PathBuf,
    pub extensions: Vec<String>,
    pub show_hidden: bool,
    pub theme_idx: usize,
    pub show_theme_panel: bool,
    pub single_pane: bool,
    pub sort_mode: SortMode,
    pub cd_on_exit: bool,
    pub editor: Editor,
    pub verbose: bool,
    pub startup_log: Vec<String>,
}

Startup configuration passed to App::new.

Grouping all constructor parameters into a single struct keeps the call sites readable and avoids the clippy::too_many_arguments limit.

Example

let app = App::new(AppOptions {
    left_dir: PathBuf::from("/home/user"),
    right_dir: PathBuf::from("/tmp"),
    ..AppOptions::default()
});

Fields

left_dir: PathBuf

Starting directory for the left pane.

right_dir: PathBuf

Starting directory for the right pane.

extensions: Vec<String>

File-extension filter (empty = show all).

show_hidden: bool

Show hidden (dot-prefixed) entries on startup.

theme_idx: usize

Index into the theme catalogue to use on startup.

show_theme_panel: bool

Whether the theme-picker side-panel should be open on startup.

single_pane: bool

Whether to start in single-pane mode.

sort_mode: SortMode

Active sort mode.

cd_on_exit: bool

Whether cd-on-exit is enabled.

editor: Editor

Which editor to open when the user presses e on a file.

verbose: bool

When true, show a debug log panel in the TUI and write logs to a file. Activated by --verbose / -v.

startup_log: Vec<String>

Pre-App log lines collected during startup (before the App existed). These are drained into App::debug_log on construction.
