dna-redux's Introduction

dna-redux

Playground for running C#/F# code in Node.js, Browsers or Native (x86/ARM).

The CIL is running in a portable .NET runtime called DotNetAnywhere (DNA).
For Node.js/Browser targets it's compiled to WebAssembly with Emscripten.

Based on the excellent works of:

@chrisdunelm https://github.com/chrisdunelm/DotNetAnywhere
@SteveSanderson https://github.com/SteveSanderson/Blazor
and contributors

Features:

Supports both C# and F#.
Runs in Node.js, Browsers or Native (x86/ARM).
Uses .NET Core 2.0 (targeting netstandard1.3 and above).
the BCL (corlib) implementation is somewhat minimal.

Changes vs stock DNA/Blazor:

added F# support.
Performance updates.
JIT updates and fixes.
corlib updates and fixes.
JavaScript interop updates.
Razor/SPA removed for clarity.

Disclaimer:

This is just an experiment to see how far can this be taken without too much effort and what the performance looks like. Obviously it would be nice to have faster GC or highly optimized JIT like RyuJIT to target WebAssembly, but you can still have fun with this now and see what the future of web development may look like.

Building:

dotnet build && npm install && npm run build
or just use build.cmd to build, VS Code to edit/run.

Running:

Running in Node.js: npm start
Running in Browser: npm run server to start a web server, then go to localhost:5000 (hint: look in the Console output)
Running as Native: see src/DNA/native
You can run it in VS Code, just select a debug config and hit F5.
The C#, C/C++, Ionide-fsharp, Debugger for Chrome and TSLint extensions for VS Code are highly recommended, but optional.

DNA Readme update

@mattwarren I referenced your excellent DotNetAnywhere write-up in this project's readme, hopefully you're ok with that, if not please let me know.

instructions?

Are there instructions for building, running and extending?

For context, I'm interested in playing around with this project as an extension of Blazor and also because I'm unable to get the Blazor source to run on a box with VS2017 15.4. Thoughts about the latter would be appreciated as well.

Adding 64-bit support

When running on x64 it crashes in Type_Init(), while loading corelib.dll. After investigating the source of the problem is the pointer size being hard-coded to 4.

This particular problem (loading an assembly) originating source is the MetaData.c file:
tableDefs and LoadSingleTable.

Error in sprintf with more than 3 parameters

Using sprintf with more than 3 parameters leads to a crash due to a bad heap pointer.

Only happens when the Fsharp.Core is compiled in release mode, works fine in debug mode.
printf works fine in either release or debug, with any number of parameters.
Possibly related to delegate invocation

error building FSharp.Core

on Windows, I get the following error when building using build.cmd:

Constrained virtual calls on interface type

Constrained virtual calls on interface types fail because they are not properly dereferenced.

segfaults on ARM32 (armv7a)

@ncave building DNA on armv7a (native) and running helloworld.dll would segfault. An F# hello world application on ARM would run if System.Console.WriteLine is used, but printfn will segfault when writing a string (unrelated to missing CustomAttributeData). Have you been able to run it on ARM ?
