Very cool, Jochen! I must check this out. The incremental properties are much better than having to handle line continuation characters. Besides that, it looks so much more like good ole Makefiles :-)

Yep, long time ago...

 

In this spirit, I wonder if there is any use in having a small preprocessor-like language so that you could do something like:

#if (property==value)
-Dmy.java.property=true
#else
-Dmy.java.property=false
#endif

You may not be astonished: I also thought about some preprocessing, e.g. conditional execution, #include "other.xargs" file etc.

I propose to collect requirements and maybe refactor the whole commandline / xargs processing.

Something like this could possibly help to make init.xargs files more portable across different platforms. Maybe that could be implemented as an extension bundle once I have correctly implemented the framework micro services to not clutter the framework.

Do you have more information about plans for "Micro services"?

The += notation was only about 5-10 lines more code, but preprocessing would indeed be more complex implementation due to size/complexity.

Bye, Jochen

Hi all,

I am currently working again on porting Eclipse SmartHome to Concierge.
For better documentation and easier use I've extended XargsFileLauncher:

1. You can also add values to launch properties with "+=" notation

e.g.
-Dprop=value1,
-Dprop+=value2

which results in property value of "value1,value2".

This is very helpful, as you can comment on properties, e.g. for very long list of bootdelegation property, e.g.

# set bootdelegation
-Dorg.osgi.framework.bootdelegation=
# for bundle org.eclipse.concierge.service.xmlparser
-Dorg.osgi.framework.bootdelegation+=javax.xml.parsers,org.xml.sax,org.xml.sax.helpers,
# for Gogo shell
-Dorg.osgi.framework.bootdelegation+=sun.reflect,


2. I'v added a "-skip" option. From this line the processing of xargs file will be stopped. So you can easily comment a huge block out for easy testing


I also added test cases for these options.

Any comments appreciated.

Jochen
