Cursive

Cursive is a TUI library - it lets you easily build rich interfaces for use in a terminal.

Getting started

Every application should start with a Cursive object. It is the main entry-point to the library.
A declarative phase then describes the structure of the UI by adding views and configuring their behaviours.
Finally, the event loop is started by calling Cursive::run.

Examples

use cursive::{Cursive, CursiveExt};
use cursive::views::TextView;

let mut siv = Cursive::new();

siv.add_layer(TextView::new("Hello World!\nPress q to quit."));

siv.add_global_callback('q', |s| s.quit());

siv.run();

Views

Views are the main components of a cursive interface. The views module contains many views to use in your application; if you don’t find what you need, you may also implement the View trait and build your own.

Callbacks

Cursive is callback-driven: it reacts to events generated by user input.

During the declarative phase, callbacks are set to trigger on specific events. These functions usually take an &mut Cursive argument, allowing them to modify the view tree at will.

Debugging

The Cursive root initializes the terminal on creation, and does cleanups on drop. While it is alive, printing to the terminal will not work as expected, making debugging a bit harder.

One solution is to redirect stderr to a file when running the application, and log to it instead of stdout.

Or you can use gdb as usual.

Themes

Cursive supports configuring the feels and looks of your application with custom themes and colors. For details see documentation of the cursive::theme module.
