Lingua Franca Alpha

This is a preliminary release of the Lingua Franca Compiler (lfc), a command-line code generator that translates Lingua Franca programs into target language programs, and an Eclipse-based IDE (integrated development environment) that provides a sophisticated editor as well as a code generator. This release supports four target languages: C, C++, Python, and Typescript. See documentation. Of the four target languages, C is the most complete. It supports all documented language features including an experimental implementation of federated execution.

The IDE is suitable for the following platforms:

• Linux (lingua-franca-rca-0.1.0-alpha-linux.gtk.x86_64.tar.gz)
• MacOS (lingua-franca-rca-0.1.0-alpha-macosx.cocoa.x86_64.tar.gz)
  • IMPORTANT NOTE: MacOS will report that lflang.app is broken because it was not signed. To execute it, please run xattr -cr lflang.app first on the command line. Eventually, we will provide a signed download.
• Windows (lingua-franca-rca-0.1.0-alpha-win32.x86_64.zip)

The lfc command line application is suitable for:

• Linux, MacOS (lfc-0.1.0-alpha.tar.gz)
• Windows (lfc-0.1.0-alpha.zip)

System Requirements

• Java 11 or up (download from Oracle)
• Various target-specific dependencies, documented here

IDE Features

• code generation
• diagram synthesis
• error forwarding from target compiler
• validation

Language Features (see language specification)

• imports
• banks
• multiports
• list-valued parameters
