The compiler backend in question currently generates .il but no .dll or .exe files. That's why I was thinking about calling Mono ilasm as a library (requiring no restart across invocations, which would require Mono ilasm to avoid static state) .

Re: [Mono-dev] ilasm as a library
Now that you mention System.Reflection, I'm not sure how you get to that statement. But I NEVER mentioned System.Reflection. I've been talking about System.Reflection.Emit which is an (entirely) different thing. https://blogs.msdn.com/jmstall/archive/2008/03/15/things-in-metadata- that-are-missing-in-reflection.aspx And what does this have to do with System.Reflection.Emit? http://weblog.ikvm.net/PermaLink.aspx?guid=9b7ada92-88d7-45c7-be83- 8e6f4f3ccb1b That's a cool source-compatible replacement for System.Reflection.Emit. So you can develop against System.Reflection.Emit and simply drop IKVM.Reflection.Emit in to replace it (or vice versa). Not everyone uses System.Reflection. The list goes on. No, not *everyone* does. But nearly everyone does it. Andreas ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
[Mono-dev] ilasm as a library
Hi, I wanted to see how gmcs generates assemblies, given that I want to do the same for the Scala.Net compiler [1] (which as of now generates .il files). I started exploring codegen.cs and found a reference to Mono.CompilerServices.SymbolWriter . That may save an intermediate step, but how about programmatically invoking the Mono IL Assembler [2] passing an in-memory .il file as input? (and BTW, can Jay generate C#-only parsers?) A code snippet on how to use Mono's ilasm as a component would be most welcome!

Re: [Mono-dev] ilasm as a library
Robert, Actually I did not mention IKVM.Reflection.Emit, nor Mono Cecil (old and new), and so on because for now I'm after a temporary solution, in the form of in-memory IL compilation (none of the CIL-emit libraries address this use case). Given that Microsoft's ilasm can only be invoked as a command-line tool, it would be great if Mono ilasm would sport a homepage showing off this capability (I for one would find a code example or two very useful). What kind of programming language is Scala? It's THE post-functional programming language! ;-) Details here: http://www.scala-lang.org/node/4960 About JayC, I made some more browsing and found this http://code.google.com/p/jayc/ , which I guess is the version gmcs uses, right?

Re: [Mono-dev] ilasm as a library
I tried that in the past, to programatically call ilasm. The issue was that the library has some static context so it can't be called multiple times. I tried to hack around using appdomains with no luck at all. Changing it to work as a library should be easy (just peek at Driver::Main for how to do it). The main core issue is fixing the issue I mentioned. I have no idea how hard to fix it because I didn't put much more than an hours looking into it.

Forgot to mention, my problem with using appdomain was the very lacking performance.
