Hi people,
I am searching for a sponsor for frown. Frown is a parser generator for Haskell. It has similar syntax to Happy, another parser generator for Haskell, but frown has a couple of features not found in happy.
* Package name : frown Version : 0.6 Upstream Author : Ralf Hinze ralf@informatik.uni-bonn.de * URL : http://www.informatik.uni-bonn.de/~ralf/frown/index.html * License : GPL version 2 Description: LALR(k) parser generator for Haskell 98
I have packaged frown because it is a build-dependency of another package I am maintaining. The package can be downloaded from my website [1] and can the source package can be downloaded by doing
dget http://moonshine.dnsalias.org/debian/unstable/frown_0.6.1-2_i386.changes
When rebuilding the package don't forget to include the complete changelog and source by using the -sa -v0.6.0-0 flags when calling dpkg-buildpackage.
Greetings Arjan Oosting

Long description:
Its salient features are: - The generated parsers are time and space efficient. On the downside, the parsers are quite large. - Frown generates four different types of parsers. As a common characteristic, the parsers are genuinely functional (ie 'table-free'); the states of the underlying LR automaton are encoded as mutually recursive functions. Three output formats use a typed stack representation, one format due to Ross Paterson (code=stackless) works even without a stack. - Encoding states as functions means that each state can be treated individually as opposed to a table driven-approach, which necessitates a uniform treatment of states. For instance, look-ahead is only used when necessary to resolve conflicts. - Frown comes with debugging and tracing facilities; the standard output format due to Doaitse Swierstra (code=standard) may be useful for teaching LR parsing. - Common grammatical patterns such as repetition of symbols can be captured using rule schemata. There are several predefined rule schemata. - Terminal symbols are arbitrary variable-free Haskell patterns or guards. Both terminal and nonterminal symbols may have an arbitrary number of synthesized attributes. - Frown comes with extensive documentation; several example grammars are included. . Furthermore, Frown supports the use of monadic lexers, monadic semantic actions, precedences and associativity, the generation of backtracking parsers, multiple start symbols, error reporting and a weak form of error correction. .
