Existing RCP / RAP compatibility classes [message #516729]

Hi,

the Single Sourcing Guideline
http://eclipsesource.com/en/info/rcp-rap-single-sourcing-gui deline/
describes several solutions for running on RCP and RAP that could be
shared and re-used. F.e. the compatibility bundle in 3.2, NLSHelper in
12.4, or a SessionSingletonBase that also works globally in a RCP
environment.

I was just wondering, do such classes already exist as a bundle that
could be used and improved or is everybody supposed to groom a custom
utility project for this?

Greetings,

Ralf

Ralf,

currently there is no such common compatibility bundle. Given the
diversity of applications I am not sure how far such a common solution
will be useful.
However, I like the idea a lot. If someone is willing to take care of
that it could be hosted in the RAP Incubator [1]. Anyone?
A more lightweight approach could be to start building a collection of
single-sourcing snippets. To start with this we could use the wiki.
Any other ideas?

Regards
Rüdiger

I really think pre-built and packaged bundle would be of great value.
For trying things out, I just created a little project
http://github.com/ralfebert/rcprap .

I really want to avoid all this crude fragmentImplementationLoaderStuff
in my application bundles because it clutters everything up to a point
that I deem unacceptable. All I needed for (reasonably) single sourcing
my example application http://www.ralfebert.de/projects/rcp_addressbook/
was this:

- NLS.get(...) that works in RCP and RAP
- Environment.isRAP()

I just created two bundles with the same package
"de.ralfebert.singlesource" for importing that provide these
classes/methods. For the NLS I even had to copy the RAP one, because I
also would prefer getting these things cached. Copying always feels bad
and the only thing that had to be changed is the getLocale() call and
removing the logging call. Couldn't this implementation be truly shared
for RCP and RAP?

Greetings,

Ralf

which requirements / responsibilities do come with this? I'd be willing to clean up /
extend / maintain the code I started in http://github.com/ralfebert/rcprap as far as
needed in my projects.

btw: another thing I found neccessary for single-sourcing is WidgetUtil.CUSTOM_VARIANT.

Greetings,

Ralf

If the project is tailored to your needs, it is probably better to
remain on github for now. Once it is more mature, we can see if it suits
a more general usage and then move it over to eclipse.org if we see fit.
Does that make sense?
