OVERVIEW

This was originally written as a perl5 script. Rather than doing bootstrapping, I foolishly decided it would be fun to write the parser IN parrot assembly, esp. as this would help implementing "eval" and "proc" (Of course, in retrospect, I really wish I had kept with the bootstrapping effort, as I think it would have generated usable results sooner. Ah well, I now know more than I want to about IMCC. =-)

This is a from-scratch implementation, based on the tcl man page(s). Another interesting project would have been to modify the tcl source and have it generate parrot directly. For some reason, I thought this would be more fun.

This may explain the several months between each time I poked my head out on the p6i list.

RUNNING TCL

A perl script called tcl.pl grabs all the various PIR source files and generates a single PIR file, tcl.imc. We then compile this to tcl.pbc.

To run the test suite, make test. If you want to also get output from the TODO tests, make devtest instead. This is NOT the tcl test suite, it's a very small subset of features that I was sick of fixing everytime I made a small change to the parser.

There are examples in the examples directory that are vaguely more interesting. To run one of the foo.tcl files in that directory, type make foo.
