Module patterns 

Common patterns for TUI applications

This module provides reusable patterns discovered while building multiple TUI apps (jira-revue, jenkins-tui, sshfs-tui, todo-tui). These patterns follow Clean Code and Single Responsibility Principle.

Modules

Module	Description
colors	GitHub Dark theme color constants
message	Message display with auto-timeout
confirm	Confirmation dialog state
async_ops	Async polling patterns with mpsc channels
config	TOML config loading utilities
keys	Layered key handling pattern

Example

use revue::patterns::*;

struct App {
    message: MessageState,
    confirm: ConfirmState,
    async_task: Option<AsyncTask<Vec<Item>>>,
}

impl App {
    fn poll(&mut self) -> bool {
        let mut needs_redraw = false;

        // Check message timeout
        needs_redraw |= self.message.check_timeout();

        // Poll async task
        if let Some(task) = &mut self.async_task {
            if let Some(result) = task.try_recv() {
                self.handle_result(result);
                self.async_task = None;
                needs_redraw = true;
            }
        }

        needs_redraw
    }
}
