M2C Modula-2 Compiler & Translator Project

Welcome to the Wiki of the M2C 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 C translator and via-C compiler that generates authentic and readable C source code.

Purpose

The intended purpose for the M2C 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 cross-compile, bootstrap and deploy M2BSK, a Modula-2 hosted compiler for the BSK subset of Modula-2 R10.

Dialects

The M2C 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/trijezdci/m2c/blob/master/m2c-grammar.gll

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

License

The M2C compiler is licensed under the GNU Lesser General Public License (LGPL) both v.2.1 and v.3.

Prerequisites

The M2C compiler is written in C99 and therefore a C99 compiler is required to build it. There are no dependencies on any third party libraries.

OS support

The M2C compiler is supported on the following operating systems:

• AmigaOS
• BSD
• Linux
• MacOS
• MS-DOS
• OpenVMS
• Windows
• Solaris

IDE support

The M2C compiler has been integrated with Vim.
