This is to ask the net, if there's enough interest in an Eiffel-3 precompiler
toolkit. Iff, we intend to make such a product available in June 1994.
EIFFEL-3 PRECOMPILER TOOLKIT
The toolkit allows to implement Eiffel-3 precompilers based on abstract
transformations of an Eiffel-3 syntax tree. It can be used to implement
language tools (e.g. static analysis, test data generators, documentation
support) or language front-ends (e.g. for concurrency extensions). The
Toolkit generates a precompiler in C source code.
The precompiler accept Eiffel-3 (and LACE/PDL) source code as input and
generate Eiffel-3 (and LACE/PDL) source code as output. The desired
functionality is to be specified as a set of syntax tree transformations
and manipulations. These are to be specified in a high level language
which allows pattern matching, unification and recursion. They make use of
a toolkit specific abstract syntax definition for Eiffel-3, LACE or PDL.
The Toolkit consists of the following components:
- "e3-ast", "lace-ast", "pdl-ast": transform Eiffel-3 source code into
an abstract syntax tree. They perform a syntax check on the input.
("e3-ast" is an improved version of the public domain "ep" tool, see
the Eiffel-FAQ for more information).
- "generate-ast-ast", generates the source code for a transformation
tool ("ast-ast"). This tool implements the desired precompiler
functionality as a set of abstract syntax tree modifications. To
communicate with the other toolkit components "ast-ast" reads and writes
abstract syntax trees from files or standard I/O.
(The transformator generator "generate-ast-ast" is identical to the
"puma" tool of the Karlsruhe compiler construction toolbox.)
- "ast-e3", "ast-lace", "ast-pdl", transform an abstract syntax tree into
Eiffel-3 source code.
