model.mirah compile error

[Arash]

Trying to compile mirah_model to make dubious work, after fixing the
Rakefile, I got this error:
mkdir -p dist
mkdir -p build

/Users/arash/prog/Source/mirah_model/src/model.mirah:149:

I'm looking at it, but I haven't quite figured it out yet.

I cleared up the issue you're having, but ran into another one. When I use the latest bitescript, I get this error https://gist.github.com/1866601#file_mirah_model_stacktrace

when I revert it back to the version that was out when the code in question was merged in, meta_model.mirah compiles, but I run into a different error

I am pretty new to Mirah and trying to learn. I find the concept of Mirah interesting. 

I am completely puzzled with this error. The type of the key is explicitly defined, why we get an error on inferring types? 

[Nick Howard]

Can you tell us more about your environment? What version of Mirah are you using?

[Arash Bizhan zadeh]

I compiled Mirah from head.

[Nick Howard]

I made some changes to mirah_model. Could you pull and tell me what you get? I wasn't able to get it to compile either but I want to verify that we get the same error.

I had to let go of my Mac, and settled down for a windows box for now.

After a lot of hassles, I managed to compile mirah on cygwin. Now trying to compile mirah_model, it insists that it cannot find appengine- sdk, but I  have already installed it.

$ rake jar

cygpath: can't convert empty path

rake aborted!

Could not find gem 'appengine-sdk (~> 1.4.0) java', which is required by gem 'mirah_model (>= 0) java', in any of the sources.

(See full trace by running task with --trace)

-------

arash@azure ~/src/mirah_model

$ gem list

cygpath: can't convert empty path

ansi (1.4.2)

appengine-sdk (1.6.2.1)

bitescript (0.1.0)

bundle (0.0.1)

bundler (1.0.22)

jruby-win32ole (0.8.5)

mirah (0.0.11.dev java)

rake (0.9.2.2, 0.8.7)

sources (0.0.1)

turn (0.9.3)

[Arash Bizhan zadeh]

That was a dumb question. 

After installing proper version of appengine-sdk, I changed the Rake file to 

  mirahc 'src', :dir => 'src', :dest => 'build', :options => ['-V']

#  mirahc 'src/model.mirah', :dir => 'src', :dest => 'build',

#         :options => ['--classpath', Dir.pwd + "/build/"]

=====

With this change, I get a lot of errors like :

Could not infer typing for nodes:

  Constant(DubyDatastorePlugin) at line 114 (child of Call(get))

C:/cygwin/home/arash/src/mirah_model/src/model.mirah:112: Could not infer typing                                                       for nodes:

  Constant(DubyDatastorePlugin) at line 114 (child of Call(get))

  macro def property(name, type)

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    DubyDatastorePlugin.get(@mirah).add_property(name, type, @call)

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  end

^^^^^

I guess my changes to Rakefile was not good. Can you help me with the Rakefile?

[Nick Howard]

Have you tried pulling the changes I added?

If I try to build a clean clone of head I get :

rake aborted!
