[ANN] Mirah 0.1.1 Released

Hey everybody, Mirah 0.1.1 has been released! This release has been a long time coming, 383 commits. Considering the repository only has had 1627 commits so far, that's a lot of changes.

Ryan Brown's work on self-hosting continues:

• The typer has moved further into Mirah
• The new self-hosted backend
• The new mirror type system

To try out the new backend, run Mirah with -N, to test the new mirrors use -T.

New Features:

• lambda macro - allows you to create closures without having to pass them to a method call. run_me = lambda(Runnable) { puts "running" }
• beginnings of better generics support
• Move map macro from List to Collection.
• Add zip, map, and reduce macros.
• Java 8 bytecode support
• Array literals are no longer immutable

Bugs fixed:

• macro lookup looks in implemented interfaces as well as classes
• improved loop detection in the typer
• static field and method lookup now checks up the inheritance hierarchy #134, #150
• better boxing of varargs values
• type conversion of assignable return types
• Fix varargs method called with array.

Removed Features:

• dynamic type -- currently dynamic support requires the dynalink jar, which is a runtime dependency. I've started a project for converting it into an extension (https://github.com/mirah/mirah-dynamic).
• fixnum has been renamed to int

Planned for next release (0.1.2)

Visibility: the new ast changes removed public/protected/private. We're going to add them back in the next

Ran into some problems w/ jar -- path issues ultimately $ java -cp dist/mirah-complete.jar org.mirah.MirahCommand run examples/tak.mirah Exception in thread "main" java.lang.NoClassDefFoundError: org/jruby/runtime/Helpers at org.mirah.MirahCommand.main(MirahCommand.java:118) Caused by: java.lang.ClassNotFoundException: org.jruby.runtime.Helpers at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ... 1 more

Hmmm

JRuby 1.7.4 changed some internal APIs so classfiles generated with it are not backwards compatible

dl new jruby-complete & cp into javalib

now java -cp dist/mirah-complete.jar org.mirah.MirahCommand run examples/simple_class.mirah

• [TypeFactory] Error initializing builtins: Unable to find class mirah.lang.ast.Block jar:file:/Users/nick/hacking/mirah_hacking/mirah/dist/mirah-complete.jar!/mirah/jvm/types/intrinsics.rb:186:in read_macrodef_annotation' org/jruby/java/proxies/ArrayJavaProxy.java:138:in each'

I'm going to try downgrading to 1.7.2

nope

the problem was that the base classpaths were wrong for the in a jar case

Maven

hmm
