pl0c

====

`pl0c` is a compiler for the

[PL/0](https://en.wikipedia.org/wiki/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](https://briancallahan.net/blog/20210814.html)

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)`](https://man.openbsd.org/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.
