kandi X-RAY | vallang Summary

vallang is a Java library typically used in Programming Style, Functional Programming applications. vallang has no bugs, it has no vulnerabilities, it has build file available and it has low support. However vallang has a Non-SPDX License. You can download it from GitHub.

Vallang is a highly integrated and mostly-closed collection of mutually recursive fundamental data-types on the Java Virtual Machine:. Operations on these data-types are too many to list here. A selection is listed below, but you should expect the features to be pretty low level; i.e. directly accessing and manipulating the data rather than providing analysis algorithms. Algorithms in the library are added only if programming them below the abstraction layer of vallang provides a major efficiency benefit or it can factors out highly common client code into a reusable feature. More on this design decision later.

            how to use "IO actions" with list comprehension or mapper in Rascal?
            Asked 2019-Feb-07 at 15:26

            I was wondering that IO actions (like println) would return a value of type void, and then we could use these actions in a list comprehension or as argument to the mapper function. However, when I try

            The reason for the null pointer is that printf is a void function. In the current implementation this is implemented as a null pointer. You could use instead



            Referencing a Java file in Rascal
            Asked 2018-Nov-08 at 15:54

            I have trouble referencing a Java file from Rascal. I want to do an operation in multiple threads, and I don't think Rascal has support for that. To try using Java source code in Rascal I first tried to reimplement the trim function of the Rascal source code. I use the following rascal code:

            What you did is right. It just requires closing the terminal and reopening it, and importing the module again, unfortunately, to bind the compiled Java code to the Rascal module. Hope that helps!



            Failing to compile/run Rascal example code
            Asked 2018-Apr-16 at 17:36

            I am trying to run the example code on this part of the documentation:



            Answered 2018-Apr-16 at 14:53

            In general, rascal works on windows, no need to worry about that.

            Is this on unstable or stable?

            Maybe it would be a better idea to move this to a GitHub issue, as that format is better suited for this kind of question.
