Isn't json-lib already a dependency available, should we use another one ?
+1 to use only one json lib in xwiki! :) It can be a case for Jackson : if we are to use that
tool for
generating livetable values, performance is a big deal.
That's my use case. I want to refactor the macros from
XWiki.LiveTableResultsMacros to generate the "JSON" in memory (using
actually plain Java data types like maps and lists/arrays) so that I
can adjust it before the response is send to the client. This way I
can avoid duplicating the code from XWiki.LiveTableResultsMacros just
to add a new property to the generated JSON or to modify the value of
an existing property.
Since json-lib is used only in xwiki-platform-oldcore by the package
plugin I think it's fine to:
* use Jackson in JSONTool
* when we refactor the package plugin into a component (if we still
needed it at that point) we can also change the code to use Jackson. I
can add a comment in the pom for this so that we don't forget about
it.
WDYT?
I'm +1 for this.
Thanks,
Marius
