[erlang-questions] Trouble with abstract code, cover and rebar3

[Vlad Dumitrescu]

Hi,

2> beam_lib:chunks("/home/vlad/projects/erlide_kernel/common/
_build/test/lib/erlide_tools/ebin/ttbe.beam", ["Abst"]).
{ok,{ttbe,[{"Abst",
            <<131,80,0,1,222,78,120,156,181,125,7,148,84,69,214,
              240,76,119,207,12,89,69,...>>}]}}

So the chunk is there...

regards,
Vlad
