Application design / Supervision structure

Recording a trace ...

Capture a single invocation of

Erlang example :

'Elixir.ExBench.Capturer':capture("/tmp/foo.txt" , [ {trace_pattern, {io, format, 2}}, {count, 1}]).

Elixir example :

ExBench.Capturer.capture("/tmp/foo.txt" , [ trace_pattern: {:io, :format, 2}, count: 1])

Supported Elixir/OTP versions

See travis build for definitive, up-to-date, test matrix.

Tricks

Make a bigger input arguments file

for i in `seq 1 10000` ;  do echo "{test1,{\"$i\", <<7,166>>, #{},[],false, #{<<\"x\">> => <<\"y\">>}}}." ; done >> test/consult.me
