./devel/happy-lib, Library for the happy parser generator for Haskell

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 2.1.5, Package name: happy-lib-2.1.5, Maintainer: pkgsrc-users

Happy is a parser generator for Haskell. Given a grammar specification
in BNF, Happy generates Haskell code to parse the grammar. Happy
works in a similar way to the yacc tool for C.

This library provides the following functionality:

* Data type definitions for the Grammar AST type, capturing the
information in .y-files
* A parser for happy grammar files (.y) to produce a Grammar
* Implementations of the text book algorithms that compute the LR
action and goto tables for the given Grammar
* An LALR code generator to produce table-driven, deterministic
parsing code in Haskell
* A (less maintained) GLR code generator to produce
table-driven, non-deterministic parsing code in Haskell, where
ambiguous parses produce multiple parse trees

devel/happy-lib: update to happy-lib-2.1.4

## 2.1.4

Move `Paths_happy_lib` into `tabular` to prevent a Cabal bug concerning
--libsubdir (#328). It is likely that this release fixes
`cabal v1-install happy` as well, which was broken since happy-2.0 (#315).
