The tarball is a little bigger - even though I removed all the python code. The reason is that I have to distribute a pre-compiled version of self/compile.c so that the compiler can be bootstrapped.
Enjoy, and feedback appreciated.
Here's the text of the README:
This is the initial release of the self-hosted compiler. It's still in a very unpolished state, but you can use it to bootstrap itself. Just run the script "util/bootstrap.py": $ python util/bootstrap.py Which does the following: 1) run gcc on the distributed version of self/compile.c 2) this binary will be used to recompile the compiler. 3) that binary will recompile the compiler again. 4) the output from steps 2 and 3 are compared, they should be identical. If you're happy with the resulting compiler, you can compile an optimized version of self/compile.c, but be warned - you'll need a lot of memory and a lot of time. I am using dragonegg for optimized builds, and that seems to take about a GB of memory, and 18 minutes to build. It's important to use '-O2', not '-O', because '-O' takes 53GB of memory and hours to compile. Very little documentation exists yet, try 'lang.html' for a brief tutorial. The best way to get familiar with the language is to read the source code in the 'self' directory, and browse over the files in "tests". -Sam
