Repl?

Could loyc macros and enhanced c# be used in a Repl?

I haven't looked into this. I think somebody wrote a C# repl ... let's see, here's one from Mono. Perhaps it could be adapted to run LeMP code.

Actually I think Roslyn has a REPL engine (CSharpScriptEngine?), and it would be better to use that one. Since it's open source, it could be adapted to take LeMP as a front-end. A REPL, in turn, would be a great starting point for a EC# Visual Studio extension that provides IntelliSense for .ecs files. Plus, maybe the REPL itself could be integrated into VS. That is, if you're interested in doing that kind of work.

Maybe I misunderstood though, maybe all you want is a REPL that runs macros. If that's what you want, LeMP.exe --editor could be used as a substitute.

Here's a fun idea: implement a C# interpreter... that could be a fun thing to do with matchCode. Maybe I should write an article about doing that...

Really though... better to just convert some code to Roslyn and then compile that

OMG, I know. I could write a quoteRoslyn macro that generates Roslyn syntax trees from EC# ones. Or I would if I had time. Btw I think I'll rename this repo to ecsharp.

@jonathanvdc actually made a REPL called LeMP-repl, but it hasn't been updated recently. However, there is a LeMPDemo.exe included in the zip file for the release. It processes input on the left side to produce output on the right side. Be careful about not saving the file - invalid input sometimes crashes LeMP, so please save your work occasionally. And of course, you can use the compileTime and precompute macros to execute Enhanced C# code (otherwise the code is merely preprocessed).

If you would like to see the Loyc tree that corresponds to some Enhanced C# code, add --outlang=les3 to the options list and click Regen.
