N. E. Wirth Language Compilers

This page documents compilers that comply with a language report of Niklaus Wirth. It does not document variants, e.g. Component Pascal, INCITS/ISO/IEC-7185:1990.

Revised Oberon-07 Compilers

Project Oberon
Wirth's reference platform since 2013, built with and including his compiler.
Astrobe
Chris Burrows fully complete (statically linked) compiler for the ARM, (CFB Software). Runs on Windows.
Patchouli
Oberon-07 compliant with the 2016 Report. Its benefit is an .exe available for Windows 64-bit. It does not appear to produce a Portable Executable, however. This was previously the AyaCompiler.
OBNC
Oberon-07 to C translator.
oberonc
Oberon-07 to Java bytecode compiler

Other Revised Oberon-07 Compilers

A2 RISC
Runs under Unix A2, and generates RISC objects that can be run with an accompanying emulator. See the Oberon Community Platform for more details on the Oberon systems (and compilers) from ETH Zürich.
oberonjs
Vladislav Folts' (and contributors) Oberon-07 to JavaScript translator. Includes a separate mode for extensions (Eberon). Implements the 2015 Oberon Report (not dynamically loaded).
Oxford Oberon Compiler
A fairly portable compiler, runs on Windows, Debian and Debian derivatives (e.g. Ubuntu), OS X, and Raspberry Pi. It uses the Objective Caml runtime, but is statically linked. Though essentially an Oberon-2 compiler, version 3 includes flags with the intent of allowing a valid Oberon-07 program to compile and run correctly (but not strictly checked). Written against the 2013 Report.
vostok
An Oberon-07 to C, and other languages, translator. Goals appear to be different dialects of Oberon-07. Code comments and output are in Russian.
Oberon-07M
A minimal commercial, statically linked, 32-bit shareware compiler from Russia, (Exact Programs). Implements classic Oberon-07 using the 2008 Report.

Oberon-07 Abandonware

nickelsworth transpiler
Akron's Oberon-07/11 compiler
Open-source (GPL) compiler for Windows by Krotov Anton. An editor and some example libraries are provided. Linking is static, but it is noteable for generating binaries for other OSes (e.g. Linux).

Oberon-0 Compilers

Oberon-0 refers to the subset language since the 1996 edition of Compiler Construction. It was extended in the 2011 edition.

Oberon Compilers
