Yes indeed, it looked quite complicated to me. Sounds like a good plan
to use QtC's watch system, i guess the only thing I'm missing is
saving the edited file on the QtC side, or maybe it's better to do
that on Qbs side (but wouldn't be consistent with group/file
I need to do some minor cleanup on my Qbs review, i really would like
to have some tests, even if they are basic.
I was thinking about adding a function to tst_api that would simulate
a full project reload, this would allow me to verify that i can add
and remove references to the toplevel project and check for error
cases, maybe another simple test to make sure it works for nested
Any objection with that approach?
