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! - - -==GF language extensions== - -Operations for defining patterns. - -Inheritance of overload groups. - - |
