printf "%064b", -100

In case someone else looks at this ticket​: I created a branch "sprintf" for nqp, in which I tried a first stab at the above problem (the evaluation works in the branch). I plan to look at other directives as well -- therefore the branch.

I also added a new test file S32-str/sprintf-b.t with in-depth tests for "%b" to roast (not in t/spectest.data in Rakudo, yet). Maybe I went to far with testing different combinations of flags, but the tests were helpful for me while working on sprintf.nqp.

Reviews/comments are very welcome.

It is actually fixed now​:

«00000000000000000000000000000000000000000000000000000000-1100100»

That comes from this bump​: (2017-11-13) rakudo/rakudo@b2fbf89

And in nqp repo it seems to be this merge​: Raku/nqp@a09c787

So the aforementioned sprintf branch was merged! ♥

I think a test won't hurt.

I've added a test for sprintf('%064b', -100) to S32-str/sprintf.t with commit Raku/roast@26cacb145a

I'm closing this ticket as 'resolved'.
