Re: Convert DS/Record to JSON

Hi Aaron,

during most of 2008 I have been down that road with Niels, 
in practice it fails because it dosn't give you what you want -
performance in development ;-)

Regards
Henrik

Re: [WEB400] Convert DS/Record to JSON






Hi Henrik,

I try to develop tools that lessen the time required for the programmer 
even
if they only address 80% of the scenarios they get involved in.  So when 
you
say it "cannot" be done, i understand where you are coming from, but to 
not
pursue it because of that I believe we then miss out on developing a few
simple tools that greatly simplify the programmers life.

> In regards to powerEXT license powerEXT has now been devided into
to seperate products/projects:

My point is that you need to have this clearly documented on your website 
so
people don't have to wonder how the code is licensed.  Is what you just
conveyed available to the user without having to download powerEXT?

BTW, I fully agree with your wanting to gain monetarily from powerEXT -
that's one of the few ways we can continue to get good open source out 
into
the community.  I have been able to gain monetarily from a number of RPGUI
projects through hourly work since it was released in Nov.  The only
difference between RPGUI and powerEXT licensing is that RPGUI is LGPL and 
my
hope is that people use it liberally everywhere so RPG can once again 
become
a mainstay on the IBM i without the need to jump ship to Java/.NET/PHP for
the front end.

> And if you consider my references to powerEXT as commercials, you
should take a look at your own homepage where the commercial reference to
the RPG-XML SUITE is all over the pages ;-)

That is a completely different context.  When I recommend RPG-XML Suite as 
a
possible solution on these lists I clearly declare that I am a vendor with 
a
licensed commercial product.
