Tom 2.6 announcement

It is our great privilege and pleasure to announce the availability of
Tom version 2.6 .

This release continues our work on the integration of pattern matching
and rule based programming facilities into Java and C.

Tom is a pattern matching compiler developed at INRIA. It is
particularly well-suited for programming various transformations on
trees/terms and XML based documents. Its design follows our research on
the semantics and the efficient compilation of rule based languages.

Many applications have been developed in Tom, both in academia and
industry. Among them, let us mention:
  - the Tom compiler itself
  - languages semantics, interpreters and program transformation tools
  - a generator of canonical abstract syntax trees (Gom)
  - a proof assistant for supernatural deduction
  - a compiler algorithm for anti-pattern matching and disunification

Tom is a complex compiler which adds powerful constructs to Java and C:
rewrite rules, strategies, non linear syntactic matching, associative
matching with neutral element (a.k.a. list-matching), XML based pattern
matching, string matching, and equational rewriting.
This offers the possibility to analyze and transform any kind of
data-structure. Tom can be used for large scale developments and
applications. It comes with a detailed documentation, as well as with
programming and debugging support.

This new release contains many improvements and new features:

- new alternative syntax for '%match', based on atomic constraints
        that can be combined with '&&' and '||' operators. This gives a
        higher expressiveness and conciseness. Works also in '%strategy'

- hand-written strategies became easier to write. No more 'Forward'
        class is needed.

- strategy support for hand-written mappings

- new tool based on ANTLR 3 for implementing parsers that
        directly output Gom terms: GomAntlrAdapter.

- term-graph rewriting support in Gom

- Gom's lists now implement the interface Collection. Consequently,
        Java's classic iteration techniques can be employed.

- several speed-ups of the compilation process as well as for the
        generated code.

- a lot of new features for the Eclipse plug-in, including the
availability of all the functionalities of the Java editor for
".t" files ( a complete list is available on the plug-in page: )

Tom is available, in open source (GPL/BSD License), from the web page:

    Best regards,
    Tom's development team
