GF 3.0

+ +Krasimir Angelov, Björn Bringert, and Aarne Ranta
+Beta release, 27 June 2008 + + +

+GF Version 3.0 is a major revision of GF. The source language is a superset of the +language in 2.9, which means backward compatibility. But the target languages, the +compiler implementation, and the functionalities (e.g. the shell) have undergone +radical changes. +

New features

+Here is a summary of the main novelties visible to the user: +

Size: the source code and the executable binary size have gone + down to about the half of 2.9. +
Portability: the new back end format PGF (Portable Grammar Format) is + much simpler than the old GFC format, and therefore easier to port to new + platforms. +
Multilingual web page support: as an example of portability, GF 3.0 provides a + compiler from PGF to JavaScript. There are also JavaScript libraries for creating + translators and syntax editors as client-side web applications. +
Incremental parsing: there is a possibility of word completion when + input strings are sent to the parser. +
Application programmer's interfaces: both source-GF and PGF formats, + the shell, and the compiler are accessible via high-level APIs. +
Resource library version 1.4: more coverage, more languages; some of + the new GF language features are exploited. +
Uniform character encoding: UTF8 in generated files, user-definable in + source files +

+ +

Non-supported features

+There are some features of GF 2.9 that will not work in the 3.0 beta release. +

Java Editor GUI: we now see the JavaScript editor as the main form of + syntax editing. +
Pre-module multi-file grammar format: the grammar format of GF before version 2.0 + is still not yet supported. +
Context-free and EBNF input grammar formats. +
Probabilistic GF grammars. +
Some output formats: LBNF. +
Some GF shell commands: while the main ones will be supported with their familiar + syntax and options, some old commands have not been included. The GF shell + command help -changes gives the actual list. +

+ +

+Users who want to have these features are welcome to contact us, +and even more welcome to contribute code that restores them! +
