The Language Machine is a free software toolkit for language and grammar. It includes a shared library, a main program, and several metalanguage compilers with one frontend. The system is easy to use on its own or as a component.

The Language Machine directly implements unrestricted rule-based grammars with actions and external interfaces. A unique diagram shows rulesets in action.

Here are some key features of "The Language Machine":

rules describe how to recognise and transform grammatical input

the left-side of a rule describes a pattern

the right-side of a rule describes how the pattern is treated

the left- and right- sides are unrestricted pattern generators

the system is a kind of symbolic engine for grammar

the metalanguage is very simple and very concise

multiple grammars, rule priorities, left-recursion, right-recursion ...

variables and associative arrays, a subset of javascript

transformed representations can include actions and side-effects

transformed representations can themselves be analysed as input

can be used as a free-standing engine or as a shared library

can be packaged together with precompiled rules

very simple interface to external procedures in C and D languages

built-in diagnostics with lm-diagram generator

several self-hosted metalanguage compilers with a single front end

compiled rules can be wrapped as shell scripts, or as C or D programs

rules can be compiled to C or D code

metalanguage source can be treated as wiki text in the Mediawiki format

What's New in This Release:

This release fixes a number of bugs which prevented the language machine from building on case-insensitive filesystems and with recent (0.149 and higher) versions of the DMD D language compiler.

It adds the j2d ruleset for translating from Java to the D language.

At present, the j2d ruleset produces D language source code that is syntactically acceptable to GDC-0.17 (e.g. for the java, javax, and gnu hierarchies in gnu classpath-0.90).
