#SCABOLIC

This is the official repository for the Scabolic source code. The aim of Scabolic is to combine in a single tool/library several automated reasoning algorithms. In particular this should (soon) support SAT/SMT solving as well as features from computer algebra.

Scabolic is written in the Scala programming language and provide (well, it will provide it in the near future) a nice Domain Specific Language (DSL) to be used either as an interactive tool within the Scala REPL or as a Scala library.

Currently, Scabolic provides two documented interfaces:

• The CafeSat tool
• A Scala API to use inner SAT solver

##Setup

This project depends on the Scala-SMTLIB library, which need to be separately built from the repository and its jar added to the classpath.

To build Scabolic simply type:

sbt package

##CafeSat

CafeSat is the tool interface to the SMT solver in Scabolic. To build CafeSat:

sbt clean
sbt compile
sbt cafesat

Then you can use CafeSat as follows:

./target/cafesat [ OPTIONS ] { INPUT ]

If no INPUT is specified, then CafeSat will expect SMT-LIB commands on the standard input, which is the standard behaviour of the SMT-LIB specifications. If an input is specified, then it will be parsed as an SMT-LIB script, and fully interpreted. Options can be used to modify this behaviour, for example the --demacs option will interpret the INPUT file in Dimacs CNF format.

The Scala'13 paper gives a short overview of CafeSat.

###Examples

To start an interactive session in the REPL with SMT-LIB:

./cafesat

To execute an SMT-LIB script you can do the following:

./cafesat < input.smt2

which simply transparently redirect stdin to the content of the file. Or use:

./cafesat input.smt2

in which CafeSat will open the file before feeding it to the SMT solver.

To solve Dimacs SAT problems, use:

./cafesat --dimacs input.cnf

##Scala API

Scabolic exports a mini API usable from Scala programs. The API is not stable yet and is expected to change frequently. It will not be backward compatible. The best way to learn the API is to look at the examples in the apps branch of this repository.
