NAME
Marpa::R3::Changes - Differences between Marpa::R2 and Marpa::R3
About this document
This document describes the incompatible differences between Marpa::R2 and Marpa::R3. (Differences that do not give rise to incompatibility are outside of its scope.) It is intended for readers already familiar with Marpa::R2, who are writing new applications for Marpa::R3, and for readers migrating Marpa::XS applications and tools to Marpa::R3.
Changes
The Stuifzand interface (PSIF) has been removed
The Stuifzand interface (PSIF), and its documentation, have been removed. Important in the development of Marpa, it now has little or now usage.
The Thin interface (THIF) is deprecated
The THIF is subject to major change, or outright removal, without further notice.
The NAIF is deprecated
The NAIF is an older interface using hashes of named variables, instead of a DSL. It is now severely deprecated. Expect it to be broken or removed shortly.
LATM is now the default
[name, values] is now the default action
Unicode now works in the SLIF DSL
Changes in names of location methods
The specific names changes of methods that deal with G1 and input locations are given below. The general idea is to make sure that all methods that use G1 locations, lengths, ranges or spans, whether as arguments or as return values, will have g1 as part of their name.
New method g1_input_span
Context::location is now Context::g1_range
New context variable, Context::g1_span
$slr->current_g1_location() is now $slr->g1_pos()
