mirah / dubious

A Web Framework Written in Mirah for running on AppEngine

Mirah

• http://groups.google.com/group/mirah
• http://github.com/mirah/mirah/issues

DESCRIPTION

Mirah is a customizable programming language featuring static types, local type inference and a heavily Ruby-inspired syntax. Mirah currently includes a typer/compiler backend for the JVM which can output JVM bytecode.

FEATURES

• Ruby-like syntax
• Compiles to .class
• Fast as Java
• No runtime library

SYNOPSIS

mirah <script.mirah>
mirah -e "inline script"
mirahc <script.mirah>
mirahc -e "inline script" # produces DashE.class

REQUIREMENTS

• Java 1.7 or higher.

INSTALL

RUBY

If your gem and rake are not from JRuby, prefix the commands with jruby -S

$ gem install mirah

JAR

Mirah is distributed as a jar through maven central. You can download the latest jar from maven.org.

ZIP

You can also install Mirah from a zip file. Download the latest stable release from https://github.com/mirah/mirah/releases. Extract it, and add bin to your $PATH to be able to use mirah, mirahc, etc.

SOURCE

Setup building locally and installing from source, you'll need jruby 1.7.12 or higher. Then just follow these commands.

To get the repository setup locally run the following:

$ git clone http://github.com/mirah/mirah.git
$ cd mirah
$ bundle install

To install mirah as a gem from source:

$ rake gem
$ gem install pkg/mirah-*.gem

To create the mirahc jar:

$ rake dist/mirahc.jar

This will create a mirahc.jar file in dist that you can run to compile mirah source files.

dubious's Issues

CSS files expire in past

using this approach with number in url, it is possible to cache into infinity
http://michal-duby.appspot.com/stylesheets/sh_style.css?1279397780

but instead, the file sends these headers:

Cache-Control:public, max-age=600
Content-Encoding:gzip

rake publish task fails

Worked through the README to get started and was able to run the app locally using 'rake server'

However, tried to run the publish task and received this:

csamuel@envigo:~/projects/dubious[master✗]
→ jrake publish
(in /Users/csamuel/projects/dubious)
rake aborted!
Don't know how to build task 'publish'
(See full trace by running task with --trace)

I'm assuming because some appengine rake tasks are not being loaded at runtime?

rake server exits immediately without any errors reported

I installed jruby via rvm, then did gem install dubious, which went as planned. I created a new project and copied the InfoProperties controller from the examples and added a route for it. Running rake server (without an Internet connection,
hence the update failure) outputs the following:

% rake 'server[127.0.0.1,8008]'

circular dependencies not allowed

Dubious should support circular dependencies between files.

Example of circular dependency I'd like to have:

class MetricsSuite
  def app(app:Webapp)
    @app = app
    self
  end

  def self.for_app(app:Webapp)
    new.app(app)
  end
end

class Webapp < Model
  def self.register(title:String)
    app = new.title(title).on_register
    app.save
    app
  end

  def on_register
    MetricsSuite.for_app(self).install
    self
  end
end

Missing dependency in Rakefile

Rakefile is missing dependency

        "#{OUTDIR}/dubious/Inflection.class",

org/mirah/Compiler.duby:4: undefined method `build_constructor' for #<BiteScript::ClassBuilder:0xc393a1>

I'm following the instructions

http://github.com/mirah/dubious/blob/master/README.rdoc

but got org/mirah/Compiler.duby:4: undefined method `build_constructor' for #BiteScript::ClassBuilder:0xc393a1 error.

dubious keeps reloading after changing app.yaml

How to reproduce:

1. run rake
2. make change to app.yaml
3. observe reloading in commandline

This happens using D003 and M007
tested with appengine 1.4.2 and appengine 1.4.0

Rakefile doesn't run server

running "rake" or "rake server" does nothing.

michal@domov:~/mystuff/doluj_cz$ rake

rake aborted!
Don't know how to build task ''

Nowhere to put non MVC classes

AFAIK there is no place to put non MVC classes (so that they get compiled into application).

I would imagine I could create some directories under the "app" folder and files would be included in my application.

{routes,asset,application}.properties - unused?

New apps place these files under config/ but there is no documentation for what is supposed to live in this files, or in what form.

Looking at the source, I also don't see where they get picked up (if at all)? Am I missing something?

Looking at the checked in examples, the routes are set directly in app.yaml, instead of routes.properties file.

The Mirah version README suggests to install cannot compile models.

Inference Error:
models/offer.duby:13: Bad Type nil

^^^^^^^^^^^^^^^^^^^ ---- this happens for each property

Cannot build dubious - class ScopedParameterMap not found

Dubious fails to build with the error shown below:

`dubious generate controller Widgets` creates singular class name

Running dubious generate controller Widgets creates a controller class called WidgetController in a file called widgets_controller.mirah instead of WidgetsController

FormHelper does not import Params

FormHelper does not import params

And the dependency is not marked in Rakefile

file "#{OUTDIR}/dubious/FormHelper.class" => [
                          "#{OUTDIR}/dubious/Inflections.class",
                          "#{OUTDIR}/dubious/InstanceTag.class",
                          "#{OUTDIR}/dubious/Params.class",
                      "#{OUTDIR}/dubious/TimeConversion.class",
                      *STDLIB_CLASSES]

appcfg.sh must be on the path

The dubious gem depends on the appengine-sdk gem, which pulls in most of the Java App Engine SDK. However, the publish task depends on appcfg.sh being on the path, so you must manually download another copy of the Java App Engine SDK to make it work. One good solution would be for the appengine-sdk gem to place appcfg.sh on the path.

I had to remove web.xml by hand after changing app.yaml

I had to remove web.xml by hand after changing app.yaml

parameters are empty when using multipart/form-data

When using multipart/form-data the request.getParameterMap is {} and thus params.for('yourmodel') is empty.

There should be a workaround so that params.for('yourmodel') still returns post data,.

File upload support

I had the need for file uploads support.

My solution uses appache commons jar (that is not included in Dubious) and it seesms Dubious itself doesn't have support for file uploads (other than blobstore which is a paid feature of appengine if I'm correct)

I would like my solution to be included in dubious or other solution for file uploads.

Readme should mention the need of installing appengine-sdk as a Jruby gem

.mirah files are not compiled

When I tried latest repository to build, I found src/*/.mirah files could not be compiled.
This is because LIB_MIRAH_SRC looks *.duby files. Perhaps forgot to push Rakefile?

Transaction inside an iteration: undefined method `defining_class' for #<Duby::AST::Block:0xc98b07>

server rake task provides no way to override listening interface

Running "rake server" always listens on localhost no matter what. It would be convenient to allow it to bind to another interface.
