# language-pig #
Parser and pretty printer for the Apache Pig scripting language (http://pig.apache.org/). The current version is implemented using Parsec parser combinators.
# Install #
Cabal project, now on hackage, so the usual
```
cabal install language-pig
```
Or from source
```
git clone ...
cd language-pig
cabal install
```
# Use #
Parse an expression:
```
parseString :: [Char] -> Root
```
Returns an AST (type is the root node).
Parse a file:
```
parseFile :: FilePath -> IO Root
```
Returns an AST (type = Root, which is the root node).
Pretty print the produced tree:
```
putStrLn $ prettyPrint tree
```
So to round it up, if you want to parse and pretty print the parsed AST of a Pig file (using Control.Applicative (<$>))
```
prettyPrint <$> parseFile "example.pig" >>= putStrLn
```
