libexp

A library for constructing computational experiments.

Example usage of the parser

You can lift a parser into the PExpT monad with .lift. This will automatically build a cross-product of the Exp monads (flatmaps them) within the parsers tuple type (~). Extraction has to be performed with the double tilde ~~, because of name clash with ordinary parser extractor when used within a parser environment.

object MyParser extends ExpParser{
    def grid: Parser[Exp[Problem]] = for (
        x ~~ y ~~ doms <- (("grid(" ~> intExp <~ ",") ~ (intExp <~ ",") ~ intExp <~ ")").lift
    ) yield generators.grid(x,y,doms)
}

This parses for example grid(1,{2,3,4},[2:6]).

Usage

To use the library, add the following lines to your .sbt file:

resolvers += "tgeier repository" at "http://companion.informatik.uni-ulm.de/~tgeier/mvn"

libraryDependencies += "de.uni-ulm" % "libexp_2.11" % "1.4.1"
