The Penn Lambda Calculator ========================== Joint work by Lucas Champollion, Josh Tauberer and Maribel Romero Department of Linguistics, University of Pennsylvania Supported by a University of Pennsylvania SAS technology grant, 2006-2007. The Penn Lambda Calculator is an interactive, graphics-based pedagogical software that helps students of formal semantics practice the typed lambda calculus and derivations of sentence-level meaning according to Heim & Kratzer (1998)-style semantics. Up-to-date information about this project is on the Lambda website: http://www.ling.upenn.edu/lambda/ and its SourceForge page: http://sourceforge.net/projects/lambdacalc Copying ------- This project is distributable under the terms of the GNU GPL (the latest version). Building -------- The project is meant to be built with NetBeans. You can also build it with Ant, by typing "ant" on the command line. The project is built into the 'dist' directory. To create the packaged Windows EXE, you must get launch4j from http://launch4j.sourceforge.net/ and extract the files into the "launch4j" subdirectory of this directory. We've been using version 2.1.3 of launch4j. The build-package.sh script in this directory is a post-build step that 1) combines all of the dependency jar files in 'dist' into to the main dist/LambdaCalculator.jar file so that that jar has no dependencies during distribution, and 2) executes launch4j to build the nice wrapped Windows EXE. Running ------- To run the .jar package dist/LambdaCalculator.jar, just run java -jar dist/LambdaCalculator.jar
