Hello,
I'm not a c.l.ada regular, but Markus Kuhn suggested I post something
about
ANTLR in case it could be of interest. ANTLR (ANother Tool for Language
Recognition)
is a pretty mature (in use for much of this decade) free, open-source
parser and
lexer generator with built-in support for building abstract syntax trees
and "tree
parsers" that apply transformations to them.
ANTLR itself is implemented in Java but produces parsers and lexers in
any language
supported by a backend. The backends currently included produce Java,
C++, HTML
(for documentation of grammars), and "Diagnostics" (for detailed
dissection of grammars).
A graphical (Java Swing) "ParseView" debugger is included for exploring
the parser's
operation visually.
I don't know what parser/lexer tools are already available in the Ada
community
but writing an Ada backend to plug into ANTLR ought to be a reasonable
project
if anyone is interested. The ANTLR home page is http://www.antlr.org/
Cheers,
Chapman Flack, Purdue University
