pl0c

pl0c is a compiler for the PL/0 language. It reads in PL/0 source code and outputs equivalent C source code.

It was written to be the subject of a series of blog posts on writing a compiler from a hands-on practical perspective for the beginner.

Building

Just run make. Then (optionally) make install.

If you are on a platform that does not include strtonum(3) in its libc, remove -DHAVE_STRTONUM from CFLAGS. In this case, you'll have to put strtonum.c in the same directory as pl0c. This will be improved.

Version

The current version is 1.0.2.

You can find a source tarball in the Releases tab.

Issues and Pull Requests

Issues and Pull Requests are accepted at any time.

If your Pull Request changes the compiler in any way, I ask that you remember to update the bootstrap compiler using make genbootstrap and including the updated bootstrap compiler as part of the Pull Request.
