Hi Dimitri
You’ve done everything right but I’ve realised my mistake is that it’s not just
the database any more, it’s the transpiled code is specific to each target and
that it what’s taking the time. So the correct solution is that I must change
QxCompiler to that several applications can be built within one target
directory.
This won’t be a probem, but I don’t think I will have time to do it today; I
should be able to sort it out this weekend though
BTW, all the classes have to be transpiled for every build; this is because
although we know that in reality, Qooxdoo and all the contribs are all ES5 that
could change so we have to assume they’re all ES6. Plus there is code removal
(eg removing qx.debug variants for build target) and we inject dependency
information for use during the boot loader (although that could be refactored)
