Extremely fast, native C#-dialect and powerful tooling for mobile and desktop developers.
Welcome to Uno, the core component in Fuse Open, a native app development tool suite.
$ npm install @fuse-open/uno
This will install the uno command and standard library.
We are currently working on beta-3.0. Releases made from this branch are tagged @beta on NPM.
Uno is a collection of compiler and platform abstraction technologies.
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 |
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)
- 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.
Please see our documentation for information about building apps.
Uno is built using the command-line on Linux, macOS or Windows – or from inside an IDE.
make
make install
uno --version
