Cursive is a TUI (Text User Interface) library for rust. It uses ncurses by default, but [other backends are available](https://github.com/gyscos/cursive/wiki/Backends).
|
|
|
|
It allows you to build rich user interfaces for terminal applications.
|
|
|
|
# [Documentation](http://docs.rs/cursive)
|
|
|
|
It is designed to be safe and easy to use:
|
|
|
|
```toml
|
|
[dependencies]
|
|
cursive = "0.13"
|
|
```
|
|
|
|
Or to use the latest git version:
|
|
|
|
```toml
|
|
[dependencies]
|
|
cursive = { git = "https://github.com/gyscos/cursive" }
|
|
```
|
|
|
|
([You will also need ncurses installed.](https://github.com/gyscos/cursive/wiki/Install-ncurses))
|
|
|
|
```rust,no_run
|
|
use cursive::Cursive;
|
|
use cursive::views::{Dialog, TextView};
|
|
|
|
fn main() {
|
|
// Creates the cursive root - required for every application.
|
|
let mut siv = Cursive::default();
|
|
|
|
// Creates a dialog with a single "Quit" button
|
|
siv.add_layer(Dialog::around(TextView::new("Hello Dialog!"))
|
|
.title("Cursive")
|
|
.button("Quit", |s| s.quit()));
|
|
|
|
// Starts the event loop.
|
|
siv.run();
|
|
}
|
|
```

## Showcases
|
|
|
|
Here are some cool applications using cursive:
|
|
|
|
* [RustyChat](https://github.com/SambaDialloB/RustyChat): Chat client made using Rust and Cursive.
|
|
* [fui](https://github.com/xliiv/fui): Add CLI & form interface to your program.

|
|
* [ripasso](https://github.com/cortex/ripasso): A simple password manager written in Rust.
|
|
|
|
## Goals
|
|
|
|
* **Ease of use.** Simple apps should be simple. Complex apps should be manageable.
|
|
* **Linux TTY Compatibility.** Colors may suffer, and UTF-8 may be too much, but most features *must* work properly on a Linux TTY.
|
|
* **Flexibility.** This library should be able to handle simple UI scripts, complex real-time applications, or even games.
|
|
* In particular, it tries to have enough features to recreate these kind of tools:
|
|
* [menuconfig](http://en.wikipedia.org/wiki/Menuconfig#/media/File:Linux_x86_3.10.0-rc2_Kernel_Configuration.png)
|
|
* [nmtui](https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/sec-Configure_a_Network_Team_Using_the_Text_User_Interface_nmtui.html)
|
|
|
|
## Compatibility
|
|
|
|
First off, terminals are messy. A small set of features is standard, but beyond that, almost every terminal has its own implementation.
|
|
|
|
### Output
|
|
|
|
* **Colors**: the basic 8-colors palette should be broadly supported. User-defined colors is not supported in the raw linux TTY, but should work in most terminals, although it's still kinda experimental.
|
|
* **UTF-8**: Currently Cursive really expects a UTF-8 locale. It may eventually get patched to support window borders on other locales, but it's not a priority.
|
|
There is initial support for [wide characters](https://en.wikipedia.org/wiki/CJK_characters). [RTL](https://en.wikipedia.org/wiki/Right-to-left) support [is planned](https://github.com/gyscos/cursive/issues/31), but still very early.
|
|
|
|
### Input
|
|
|
|
* The `key_codes` example can be a useful tool to see how the library reacts to various key presses.
|
|
* Keep in mind that if the terminal has shortcuts registered, they probably won't be transmitted to the app.
|
|
* UTF-8 input should work fine in a unicode-enabled terminal emulator, but raw linux TTY may be more capricious.
