M2J Modula-2 Compiler & Translator Project

Welcome to the Wiki of the M2J Modula-2 Compiler & Translator Project

Objective

The objective of this project is to develop a highly portable, reliable, readable and maintainable multi-dialect Modula-2 to Java translator and via-Java compiler that is feature compatible with the M2C and M2Sharp translators/compilers.

Purpose

The purpose of the M2J compiler is to provide a means:

• to compile and run program examples from early Modula-2 books (PIM3/PIM4), in particular works by Wirth.
• to develop, build and bootstrap a JVM compiler for Modula-2 Revision 2010 written in a subset of M2 R10.

Dialects

The M2J compiler shall support the classic Modula-2 language described in the third and fourth editions of "Programming in Modula-2" (Wirth, 1983-1985) and selected features of the revised Modula-2 language described in "Modula-2 Revision 2010" (Kowarsch and Sutcliffe, 2010-2015). For details, see section Dialects & Language. The ISO Modula-2 dialect will not be supported.

Grammar

The grammar of the compiler is in the project repository

https://github.com/m2sf/m2j/blob/master/m2j-grammar.gll

For graphical representation of the grammar, see section Syntax Diagrams.

License

The M2J compiler is licensed under the GNU Lesser General Public License (LGPL) both v.2.1 and v.3.

Prerequisites

The M2J compiler is written in Java and therefore a Java compiler is required to build it. There are no dependencies on any third party libraries. A Java execution environment is required to execute it.

OS support

The M2J compiler will run on any operating system with a Java execution environment installed.

IDE support

The M2J compiler will be integrated with Vim and Eclipse.
