Current Work

• Antlr5-Specs, Antlr5, the next version of Antlr.
• Trash, a collection of command-line tools that extend Antlr4 with parsing analysis, grammar analysis, parse tree refactoring, and parsing driver template generation.
• g4-scripts, a collection of command-line scripts that use Trash.
• Antlr grammars, adding CI for non-Java targets.
• Scraping the Antlr grammar from the Dart language Specification.
• Antlr4BuildTasks, build rules for C# Antlr4 programs using Antlr tool jar and Java.
• Antlr4Templates, templates for simple Antlr4 console programs.
• Scraping the CFG from the ISO C++ Specs
• Trash on the Web, a website for the static analysis parser generator grammars, including Antlr2, 3, 4, Bison, EBNF, ABNF, Lark, Pest, etc.
• StringTemplate4, updating.
• Antlr, fixing bugs.
• Antlr4 PHP runtime, fixing bugs.
• Antlr4-lab, suggesting new features.
• Scraping the grammar for Java from the online Java language spec
• Automating transformations to optimize the Java grammar for parsing speed.
• Implementing Zhang-Shasha tree diff algorithm in C#, to be applied in grammar diff utility.

campy's Issues

Getting Started - NuGet versions / DllLoadException

Your project looks cool, but we're struggling to get things running.

For the Visual Studio project we get errors finding the swigged.llvm package version 70.0.0 (which one of your comments indicated have not been published yet).

For the command line / bash instructions we compile successfully, but then get an error:

• "DllLoadException - Unable to load DLL campy-runtime-wrapper", even though the .dll is present in the 'publish' directory.

We're running VS 2017 under Windows 10.

Can you give any advise on how we might try to get a running version?
Do we also have to compile and package swigged.llvm and publish to a local dir, or can you suggest a simpler route?

Math.Log(10) failed

I'm trying to Math.Log(10), but failed.
System.Exception: 'Cannot find System.Double System.Math::Log(System.Double)

What's the difference between ManagedCuda and Campy

Hi @kaby76 Could you explaine a little bit about the difference betwee ManagedCuda and Campy? I'm just confusied to choose.

CUDA error: invalid argument

            int n = 10;
            var rand = new Random();
            double[] x = new double[n];
            double[] y = new double[n];
            for (int i = 0; i < n; i++)
            {
                x[i] = rand.NextDouble();
            }

            Campy.Parallel.For(n, i => y[i] = 1 / (1 + Math.Pow(Math.E, -x[i])));

It works in console, but failed in UnitTest project.

DNA improvements

Hello fellow DNA enthusiast!

This is not really an issue, more of a question.

As a maintainer of another DNA clone, it would be very interesting to understand better the extent of your changes on top of the original DNA (a Blazor fork as baseline, I assume), for example what did you fix for 64-bit support, or anything else from the top of your head that you wish to share.

Just skimming through the code, I see these changes:

• added function_space_specifier to functions
• replaced allocation functions
• replaced string functions
• replaced the JIT and the JIT runner with Mono.Cecil (but why).

I'm sure this only touches the surface, perhaps I'm missing some of the changes.

Looks like an awesome project, the GPU target looks very interesting.

Thank you, I appreciate your help and time.
