The Language Machine 0.2.3

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.
Main features:
- 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
Enhancements:
- modifications for compatibility with gdc-0.22 and dmd-1.010
- element.d - wrong indices to non-keyword array literal cells
- add src/dmd/Makefile for building with dmd compiler
