Brainf*** .NET Compiler

I've been experimenting for the last couple of days with creation of executables in C# using the Reflection.Emit namespace.

As a first project, I've created a small compiler for the Brainf*** language in C#. The code's provided at the bottom of the page as a simple example of IL generation in C#. The code is freely redistributable.

The parser is a simple stack-based parser. All characters other than the eight BF command characters are ignored.

I've tested it with Hello World and a few numerical examples, as well as Frans Fasse's self-interpreter, all of which seem to compile and work correctly. Please use the comments area to report any bugs.

After compilation, a BF program stored in a text file can be compiled from the command line with the command

bf.exe <input file> <output filename> <tape size>

where the last parameter is the size of the BF tape required to execute the program (implemented for now as a fixed-length array after compilation).

For example,

bf.exe hello.bf hello.exe 1024

will compile the source in hello.bf with a tape of 1024 integers to hello.exe.

Enjoy!
