To actually interface with the terminal, Cursive uses a backend library. While this currently defaults to crossterm, a few other backends are available and can be enabled with cargo features.

• crossterm-backend (default starting in cursive 0.21): uses the pure-rust crossterm library. Works crossplatform, even for windows systems down to version 7.

• ncurses-backend (was the default up to cursive 0.20 included): uses the ncurses-rs library directly. Currently only compatible on Linux and macOS. Requires ncurses to be installed on the system.

• pancurses-backend: uses the pancurses library, which forwards calls to ncurses-rs on Linux/macOS or pdcurses-sys on Windows. Requires ncurses to be installed on the system.

• termion-backend: uses the pure-rust termion library. Works on Linux, macOS, and Redox.

• blt-backend: uses the cross-platform BearLibTerminal.rs binding. Works on Linux and Windows.

  Note: BearLibTerminal is a graphical application emulating a terminal. There is an archlinux package, or you can download a release.

To use a different backend, you will have to disable the default features and enable the desired backend feature.

To run an example from the cursive source code, you can run:

cargo run -v --no-default-features --features pancurses-backend --example select

To select a specific backend in your application:

# Cargo.toml

[dependencies.cursive]
version = "0.20"
default-features = false
features = ["blt-backend"]

Or you can leave the choice to compilation time, forwarding cursive's features to your own application:

# Cargo.toml

[dependencies.cursive]
version = "0.20"
default-features = false

[features]
default = ["ncurses-backend"]
ncurses-backend = ["cursive/ncurses-backend"]
pancurses-backend = ["cursive/pancurses-backend"]
termion-backend = ["cursive/termion-backend"]
crossterm-backend = ["cursive/crossterm-backend"]
blt-backend = ["cursive/blt-backend"]

You need BearLibTerminal.lib file (to be downloaded on BearLibTerminal homepage) and copy it to
