NAME

pmc2c.pl - PMC compiler

SYNOPSIS

perl pmc2c.pl foo.pmc

DESCRIPTION

Compile the PMC file listed on the command line, producing a corresponding .c file.

PMC FILE SYNTAX

The basic syntax of a PMC file is

1. A preamble, consisting of code to be copied directly to the .c file

2. pmclass PMCNAME [extends PMCNAME] {

3. A list of vtable method implementations

4. The final close }

METHOD BODY SUBSTITUTIONS

The vtable method bodies can use the following substitutions:

• SELF - Converted to the current PMC object of type PMC*.

• INTERP - Converted to the interpreter object.

• SELF.method(a,b,c) - calls the vtable method 'method' using the static type of SELF (in other words, calls another method defined in the same file).

• DYNSELF.method(a,b,c) - calls the vtable method 'method' using the dynamic type of SELF

• DYNSELF(a,b,c) - same as above, but calls the current method

• SUPER(a,b,c) - calls the overridden implementation of the current method in the nearest superclass, using the static type of SELF.

• DYNSUPER(a,b,c) - as above, but uses the actual dynamic type of SELF.
