I've never tried writing a data formatter, but custom summary
formats hardly ever work, so much so that I never even bother
trying to use them any more. You can get them to work once just to
tantalize you and cause you to waste loads of time, but then they
never work again. I just use "View as Memory" or use the debugger
console to print stuff out. The Expressions window would be
potentially useful here but it's just too annoying - half the time
you get the dreaded "Out of scope" and if you mistype, you can't
select an existing expression and edit it, you have to type it all
over again. In the console you've got editing built in so it's much
easier.
I know what you mean, but I do use summary formats and they
generally do work after an insane amount of trial and error.
What I find is that you spend ages trying to get one to work, for
example, to print out a custom string class, and then you never see it
work again - you just get the grayed out summary expression. Sometimes
it'll work the first time round a loop and then the second time it
fails. The built in ones are no better - sometimes I see a std::string
printed out but it's a rare event and it's not worth moving your gaze
to the summary column - easier to keep opening up the class down to
the M_dataplus pointer. std::vector hardly ever works either - it has
those "first", "last" and "all" buttons but they never do anything,
but just once in a blue moon you'll actually see the items in the
vector so the code must work somewhere.
