# xdialog
[![Version](https://img.shields.io/crates/v/xdialog?style=flat-square)](https://crates.io/crates/xdialog)
[![License](https://img.shields.io/crates/l/xdialog?style=flat-square)](https://github.com/velopack/xdialog/blob/master/LICENSE)

A cross-platform library for displaying native(-ish) dialogs in Rust. This library does not
use native system dialogs, but instead creates its own dialog windows which are designed to
look and feel like native dialogs. This allows for a simplified API and consistent behavior.

This is not a replacement for a proper GUI framework. It is meant to be used for CLI / background
applications which occasionally need to show dialogs (such as alerts, or progress) to the user.

It's main use-case is for the [Velopack](https://velopack.io) application installation and
update framework.

## Features
- Cross-platform: works on Windows, MacOS, and Linux
- Zero dependencies on Windows or MacOS, only requires X11 on Linux.
- Very small size (as little as 100kb added to your binary with optimal settings)
- Simple and consistent API across all platforms

## Installation

Add the following to your `Cargo.toml`:
```toml
[dependencies]
xdialog = "0" # replace with the latest version
```

Or, run the following command:
```sh
cargo install xdialog
```

## Usage
Since some platforms require UI to be run on the main thread, xdialog expects to own the
main thread, and will launch your core application logic in another thread.

```rust
use xdialog::*;

fn main() -> i32 {
  XDialogBuilder::new().run(your_main_logic)
}

fn your_main_logic() -> i32 {

  // ... do something here

  let should_update_now = show_message_yes_no(
    "My App Incorporated",
    "New version available",
    "Would you like to to the new version now?",
    XDialogIcon::Warning,
  ).unwrap();

  if !should_update_now {
    return -1; // user declined the dialog
  }

  // ... do something here

  let progress = show_progress(
    "My App Incorporated",
    "Main instruction",
    "Body text",
    XDialogIcon::Information
  ).unwrap();

  progress.set_value(0.5).unwrap();
  progress.set_text("Extracting...").unwrap();
  std::thread::sleep(std::time::Duration::from_secs(3));

  progress.set_value(1.0).unwrap();
  progress.set_text("Updating...").unwrap();
  std::thread::sleep(std::time::Duration::from_secs(3));

  progress.set_indeterminate().unwrap();
  progress.set_text("Wrapping Up...").unwrap();
  std::thread::sleep(std::time::Duration::from_secs(3));

  progress.close().unwrap();
  0 // return exit code
}
```

There are more examples in the `examples` directory.
```sh
cargo run --example various_options
```

## Build Dependencies
This library uses [fltk-rs](https://github.com/fltk-rs/fltk-rs) for it's primary backend.
By default, [fltk-rs](https://github.com/fltk-rs/fltk-rs) provides pre-compiled binaries for
most platforms (win-x64, linux-x64, linux-arm64, mac-x64, mac-arm64).

If you are compiling for a platform that does not have pre-compiled binaries, you will need
to disable the `fltk-bundled` feature and ensure that cmake is installed on your system.

```toml
[dependencies]
xdialog = { version = "0", default-features = false }
