TITLE

PGE.pir - main module for the Parrot Grammar Engine

SYNOPSIS

    ...
    .local pmc pgec
    loadbytecode "pge.pir"
    pgec = global "_pge_compile"
    ...
    rule = pgec("^(From|To):")
    match = rule($S0)
    ...

DESCRIPTION

This module contains the routines and constants necessary to use the Parrot Grammar Engine.

FUNCTIONS

rulesub = p6rule( pattern )

(rulesub, pir) = p6rule( pattern )

Compiles a string containing a pattern into a subroutine that can be used to match strings containing the pattern. The first form simply returns a subroutine; the second form also returns a string containing the intermediate PIR code that was generated to produce the subroutine.

rulesub = p5re( pattern )

(rulesub, pir) = p5re( pattern )

Compiles a string containing a pattern into a subroutine that can be used to match strings containing the pattern. The first form simply returns a subroutine; the second form also returns a string containing the intermediate PIR code that was generated to produce the subroutine.

rulesub = pge_glob( pattern )

(rulesub, pir) = pge_glob( pattern )

Compiles a string containing a glob pattern into a subroutine that can be used to match strings containing the pattern. The first form simply returns a subroutine; the second form also returns a string containing the intermediate PIR code that was generated to produce the subroutine.
