Welcome to Uno, the core component in [Fuse Open], a native app development tool suite.
## Install
```
$ npm install @fuse-open/uno
```
This will install the [`uno`][doc2] command and standard library.
### Beta releases
We are currently working on [`beta-3.0`](https://github.com/fuse-open/uno/tree/beta-3.0). Releases made from this branch are tagged `@beta` on NPM.
### Related packages
* [android-build-tools](https://www.npmjs.com/package/android-build-tools)
* [fuse-sdk](https://www.npmjs.com/package/fuse-sdk)
* [fuselibs](https://www.npmjs.com/package/@fuse-open/fuselibs)
## Introduction
Uno is a collection of compiler and platform abstraction technologies.
* [Uno programming language](src/compiler)
* [UX markup language](src/ux)
* [Project tooling](src/tool)
* [Standard library](lib)
* [Test runner](src/test)
Uno is used on Linux, macOS and Windows, and makes native apps for the following platforms:
| Platform | Build targets |
|:----------|:-------------------------|
| Android | `android`, `android-emu` |
| iOS | `ios`, `ios-sim` |
| Linux | `native`, `dotnet` |
| macOS | `native`, `dotnet` |
| Windows | `native`, `dotnet` |

### Uno syntax
```uno
class Program
{
static void Main()
{
debug_log "Hello, World!";
}
}
```
The Uno programming language is a fast, native dialect of [C#] that can cross-compile to *any native platform* (in theory),
by emitting portable [C++17] for mobile or desktop platforms, or [CIL bytecode] for desktop platforms (Mono/.NET) —
designed for developing high-performance UI-engines, platform abstractions or integrations, and other kinds of
software traditionally required written in native C/C++.
Access all APIs and features on the target platforms directly in Uno — add a snippet of *foreign code*, and
our compiler automatically generates the glue necessary to interoperate (two-way) with a foreign language.
The following foreign languages are supported:
* [C++17], [C99]
* [Java] (Android)
* [Objective-C] (iOS, macOS)
* [Swift] (iOS)

### Run-time features
* Memory in Uno is managed *semi-automatically* by [automatic reference counting], avoiding unpredictable GC stalls.
* *Real* [generics] – sharing the same compiled code in all generic type instantiations, without [boxing] values, and with
*full run-time type system* support – avoiding exploding code-size and compile-times (while still being fast).
* *(Opt-in)* [reflection] on *all* platforms – to dynamically create objects and invoke methods based on type information
*only known at run-time* – enabling high-level Fuse features such as *live-previewing UX documents*.

## Build Instructions
Uno is built using the command-line on Linux, macOS or Windows – or [from inside an IDE](docs/build-instructions.md#building-from-an-ide).
```
make
make install
uno --version
```
> Please see [the build instructions](docs/build-instructions.md) for details
on how to build the source code.
## Configuration
> Please see [the configuration reference documentation][doc1] for details on how to
set up uno's configuration files for your build-environment.
## Command Line Reference
> Please see [the command-line reference documentation][doc2] for details on how to
use uno's command-line interface.
