Introduction

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
iOS ios
Linux native, dotnet
macOS native, dotnet
Windows native, dotnet

Uno syntax

class App : Uno.Application
{
    public App()
    {
        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:

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.

Please see our documentation for information about building apps.

Build Instructions

Uno is built using the command-line on Linux, macOS or Windows – or from inside an IDE.

make
make install
uno --version

Please see the build instructions for details on how to build the source code.

Configuration

Please see the configuration reference documentation for details on how to set up uno's configuration files for your build-environment.

Command Line Reference
