We very recently had a long paper on ParaSail published in the relatively new Journal of the Art, Science, and Engineering of Programming (http://programming-journal.org). This is an interesting...
View ArticleString interpolation comes to ParaSail 8.0
ParaSail supports generic functions where the type of the parameter is determined at the point of call. The most common use of this capability is with the string concatenation operator "|": interface...

We have just made a release of the ParaSail interpreter, VM, llvm-based compiler, and ParaScope static analysis tool (aka "static catcher of programming errors"). This is version 7.0. It includes a...
View ArticleParaSail source release 6.5 now available.
We have just made a release of the ParaSail interpreter, VM, and compiler. This is version 6.5, and is mostly a bug-fix release relative to 6.3. We are working on a static analyzer and optimizer for...
