  frown - LALR(k) parser generator for Haskell 98
 
 Before I read the documentation, how does it compare with Parsec and
 Happy which are already in Debian?

Well Parsec is no parser generator but a parser combinator library so
with Parsec you write the parser in Haskell itself. Happy and Frown are
parser generators and take a file with a BNF and generate a lot of
Haskell code implementing the parser. (quite simular to yacc and bison
for C).

Happy can only use LALR(1) grammars which means that it can not generate
parsers for a lot of grammars (for instance Haskell itself). Frown on
the other hand is LALR(k) which means that the look-ahead can be greater
than 1 and Frown can generate parsers for more grammars. 

(Note: Happy can generate parser for more extensive grammars since
version 1.15 when the GLR mode was added)

The parsers generated by Frown are also faster and use less memory
according to the author.

Greetings Arjan

Hi potential sponsors,

As I am still in the NM queue I am searching for a sponsor for frown.

* Package name: from 
  Version : 0.6.1-2
  Upstream Author : Ralf Hinze [EMAIL PROTECTED]
* URL : http://www.informatik.uni-bonn.de/~ralf/frown/index.html
* License : GPLv2
  Section : devel

It builds these binary packages:
frown - LALR(k) parser generator for Haskell 98

The package is linda an lintian clean.

An upload would close ITP bug 336978.

The package can be downloaded from my repository:
- URL: http://moonshine.dnsalias.org/debian/unstable
- Source repo: deb-src http://moonshine.dnsalias.org/debian unstable/
- dget http://moonshine.dnsalias.org/debian/unstable/frown_0.6.1-2_i386.changes

An upload would be appreciated.

Greetings Arjan Oosting
