Juliac 2.7
----------
Juliac is a framework for generating and compiling the source code of the
infrastructure (so called membranes) that is needed to run a Fractal/Java
application. The application can then be run without having to use ASM to
generate on-the-fly classes for interfaces, controllers and merge strategies.
Juliac is an alternative to Julia in cases where dynamic code generation and
loading is problematic. The idea behind Juliac is close to that of Think
(but for Java of course). Currently, four optimization levels have been
implemented in Juliac: MERGE_ALL, OO (controllers implemented as separate
objects), COMP (component-based control membranes) and ULTRA_MERGE. Juliac can
be configured to accept other user-defined optimization levels.
The name Juliac stands for "Julia Compiler" and was proposed by Philippe Merle.
Juliac is a free software distributed under the terms of the GNU Lesser
General Public license. Juliac is written in Java.

3. Compiling and installing Juliac
4. Running the sample applications
5. Compiling and running your own applications
6. References
1. Requirements
---------------
Maven 2.0.x is required to compile and run Juliac.
See http://maven.apache.org for instructions on downloading and using Maven.
2. Introduction
---------------
Juliac is composed of:
- all: the superset of all Juliac Maven artifacts (excluding extension),
- api: the core API of Juliac,
- commons: common utility functions,
- core: the code generation framework,
- examples: sample applications and tests,
- extension: extensions to Juliac,
- module: modules for Juliac (ADL parsers, compilers, generators, Spoon),
- mojo: a Maven plugin for Juliac,
- runtime: the library needed to run an application compiled with Juliac.
The following samples applications are available in the examples directory:
- comanche: the Comanche web server application,
- helloworld: the Fractal Hello World application.
In addition the examples/advanced directory contains some advanced samples. See
the README.txt in the corresponding directories to obtain more information about
these samples.
- comp-based-membrane: programming a custom component-based control membrane,
- foobar-cases: FooBar examples,
- helloworld-bin: binary components (compiled classes) with Juliac,
- helloworld-janino: the Fractal Hello World example with the Janino compiler,
- helloworld-mindadl: the Fractal Hello World example with the Mind ADL,
- large: large component assemblies,
- mix: the Fractal Hello World example with different optimization levels,
- ultra-merge: examples with the ultra-merge optimization level.
The extension directory contains some extensions to Juliac:
- adlet: the support of annotated architecture descriptors,
- dream: the support for Dream and COSMOS frameworks,
- fraclet: the support for Fraclet annotated Fractal components,
- osgi: the support for OSGi Equinox, Felix, JBoss, Knopflerfish frameworks,
- scala: the support for the Scala language.
3. Compiling and installing Juliac
----------------------------------
To compile and install Juliac in your Maven local repository, from the root
directory where Juliac has been installed, type:
mvn install
4. Running the sample applications
----------------------------------
To compile and run the sample applications, type:
cd examples/xxx (where xxx is the directory name of the sample)
mvn -Pjuliac:run
5. Compiling and running your own applications
----------------------------------------------
The quickest way for using Juliac is to mimic the organization of the
examples/helloworld module. The source and the resources of the application
should be put under respectively, src/main/java and src/main/resources.
5.1 Compiling
-------------
A Maven plugin is available for compiling applications with Juliac. As
illustrated in the examples/helloworld module, the plugin can be configured as
follows:
01 <build>
02 <plugins>
03 <plugin>
04 <groupId>org.ow2.fractal.juliac</groupId>
05 <artifactId>maven-juliac-plugin</artifactId>
06 <version>2.6</version>
07 <executions>
08 <execution>
09 <id>juliac-compile</id>
10 <phase>generate-sources</phase>
11 <goals><goal>compile</goal></goals>
12 </execution>
13 </executions>
14 <configuration>
15 <srcs><src>src/main/java</src></srcs>
16 <adls><adl>example.hw.HelloWorld</adl></adls>
17 <modules>
18 <module>JCAPI</module>
19 <module>FRACTAL_ADL</module>
20 <module>OO</module>
21 </modules>
22 </configuration>
23 </plugin>
24 </plugins>
25 </build>
Lines 14 to 22 in the <configuration> section particularly matter for the
configuration of Juliac. The following tags are supported:
- <srcs> list of directories containing the source code of the application,
- <adls> list of Fractal-ADL types to be compiled by Juliac,
- <modules> list of modules to be loaded by Juliac.
See http://fractal.ow2.org/juliac-mojo for additional information about the
Juliac Maven plugin.
5.2 Running
-----------
Once compiled with Juliac, applications can be run with the
org.objectweb.fractal.juliac.runtime.Juliac Fractal provider class. The
<juliac.run.component> and <juliac.run.interface> properties allow specifying
respectively, the component and the interface to invoke. These properties
configure the juliac:run profile that is defined in juliac/pom.xml.
For example, when configured with:
<juliac.run.component>example.hw.HelloWorld</juliac.run.component>
<juliac.run.interface>r</juliac.run.interface>
the command:
mvn -Pjuliac:run
launches the example.hw.HelloWorld component by invoking the interface named r.
5.3 Optimization levels
-----------------------
Four optimization levels have been implemented and may be specified in the <opt>
tag:
- COMP: component-based control membranes (Juliac version of Koch),
- MERGE_ALL: the content, the control and the interceptors are merged,
- OO: controllers are implemented as independent objects,
- ULTRA_MERGE: a non-reconfigurable version of the application is generated in
one unique class.
In addition, a custom optimization level may be specified. In this case, the
value of the <opt> tag must be the fully-qualified name of a class that
implements the org.objectweb.fractal.juliac.FCSourceCodeGeneratorItf interface.

core/
* dump generated files to disk only when one is sure that the generation process
is over and everything went right. The purpose is to prevent generating
incomplete code that cannot be compiled. The issue arised with the
<gracefulExit> MOJO option. The issue was partially solved in r10816 (see
Juliac#generateSourceCodeOverride(ClassGeneratorItf)), by first generating
code in memory and then dumping the code onto disk once the generation is over
and has thus been completed without error. Yet the solution is not fully
satisfactory as it may happen that files in a group may be dependent from each
others, and in this case the compilation would still fail with a missing type
exception. The issue may arise for example when generating an initializer
class that references other generated types such as interceptor, interface or
controller implementations.
* when Juliac is invoked programmatically, support in memory code generation and
compilation when no value is defined for the --gensrc and --genclass
parameters. Retain the current behavior to generate in the default locations
for the MOJO and the command line.
* provide a --gensrcjar for packaging the generated source code in a jar file
* expose Juliac as a Fractal provider class.
The idea is to generated the source code during the first run of the
application in order to be able to reuse it for later runs.
* proxy generation
* fix generic type variable conflicts between the implemented interface and
the extended class. This conflict occurs for example in Tinfi when
generating proxies for generic interfaces (e.g.
BindingFactoryPlugin<E extends ExportHints, B extends BindHints>) from
the Binding Factory. In this case, the extended class is ServiceReference<B>
and the identifier B clashes with the one from BindingFactoryPlugin.
* provide a command line option for generating proxy (interface and interceptor)
implementations similar to the <proxy><signature><controllerDesc> parameters
available for the MOJO.
extension/osgi/
* support OSGi properties (requested by Philippe)
* enable changing the bundle which is associated with a osgiPrimitive component
(suggestion by Valerio)
mojo/
* mvn clean checks the availability of the maven-juliac-plugin even though this
plugin is not required when performing mvn clean. This causes mvn clean to
fail if the MOJO has not been installed before (bug reported by Denis.)
* re-investigate with recent versions of Java the way class loaders are built.
The idea would be to retrieve a class loader that would have been built by
Maven based on the plugin dependency specifications only, and not on custom
artifact resolution. Taking inspiration from the Maven exec MOJO would be a
good idea.
module/
* investigate a new optimization level source code generator which takes place
between mergeall and ultra-merge. The idea is to keep business objects as this
and to generate a Java factory that instantiates the assembly using reflection
without any infrastructure (membrane, interceptor, interface object) code.
