Pinchot.Examples

Examples for the use of Pinchot. You wil want to look at the source code for the modules; examining just the Haddocks shows you the code that the Template Haskell ultimately generates.

In Pinchot.Examples.Postal is an example grammar for US postal addresses.

Pinchot.Examples.PostalAstAllRules shows you how to use allRulesToTypes and earleyGrammar, while Pinchot.Examples.PostalAstRuleTree shows you how to use ruleTreeToTypes and earleyGrammar.

Pinchot.Examples.AllEarleyGrammars shows you how to use allEarleyGrammars.

Three executables are included in the pinchot package. To get them, compile pinchot with the executables Cabal flag.

The print-postal-grammar executable will pretty print the Haskell source that results from applying earleyGrammar to the postal grammar.

The postal-parser executable takes as its first and sole argument a string. It parses the string using the postal grammar and pretty prints the resultin parses to standard output.

The parrot executable takes as its first and sole argument a string. It parses the string using the postal grammar. For every result that is returned (there might be zero, or one, or more than one) the result is reduced to terminal symbols using the terminals function and the result is printed to standard output.
