Welcome to the Wiki of the M2BSK Modula-2 Bootstrap Kernel Project
The objective of this project is to develop a bootstrap compiler for the revised Modula-2 language described in "Modula-2 Revision 2010" (Kowarsch and Sutcliffe, 2010-2015).
The purpose of the M2BSK compiler is to facilitate bootstrapping of a self-hosting compiler for Modula-2 R10.
The M2BSK compiler supports the Bootstrap Kernel (BSK) subset of Modula-2 R10. It does not support the full Modula-2 R10 specification, nor earlier PIM or ISO dialects.
The grammar of the compiler is in the project repository
https://github.com/m2sf/m2bsk/blob/master/m2bsk-grammar.gll
For a graphical representation of the grammar, see section Syntax Diagrams.
The complete language specification (PDF) can be found here:
https://github.com/m2sf/PDFs/blob/master/M2BSK%20Language%20Description.pdf
The M2BSK compiler will generate classic Modula-2 sources that can be compiled with any Modula-2 compiler that meets the prerequisites for compiling M2BSK itself. An LLVM backend will be added later to generate LLVM IR.
M2BSK is licensed under the GNU Lesser General Public License (LGPL) both v.2.1 and v.3.
The M2BSK compiler is written in the Modula-2 dialect described in the third and fourth editions of Niklaus Wirth's "Programming in Modula-2". Therefore any Modula-2 compiler that supports PIM3, PIM4 or ISO Modula-2 should be able to compile the sources.
The following libraries from Wirth's "Programming in Modula-2" are required.
- Storage
- Terminal
- FileSystem
These libraries should be part of any PIM Modula-2 compiler's library. For use with ISO Modula-2 compilers, M2BSK provides shim libraries for adaptation to ISO Modula-2 libraries.
There are no dependencies on any third party libraries.
M2BSK will run on any operating system with target support by the host-compiler.
