v0.1.0-alpha (06-04-2021)

Pre-release
Pre-release

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

IDE Features

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