Adds the object_id id
to the set of objects being pretty printed, so as to not repeat objects.

If the stream begins with a BOM (byte order marker), consumes the BOM and sets the external encoding accordingly; returns the result encoding if found, or nil
otherwise:
File.write('t.tmp', "\u{FEFF}abc") io = File.open('t.tmp', 'rb') io.set_encoding_by_bom # => #<Encoding:UTF-8> io.close File.write('t.tmp', 'abc') io = File.open('t.tmp', 'rb') io.set_encoding_by_bom # => nil io.close
Raises an exception if the stream is not binmode or its encoding has already been set.
If the SOURCE_DATE_EPOCH environment variable is set, returns it’s value. Otherwise, returns the time that Gem.source_date_epoch_string
was first called in the same format as SOURCE_DATE_EPOCH.
NOTE(@duckinator): The implementation is a tad weird because we want to:
1. Make builds reproducible by default, by having this function always return the same result during a given run. 2. Allow changing ENV['SOURCE_DATE_EPOCH'] at runtime, since multiple tests that set this variable will be run in a single process.
If you simplify this function and a lot of tests fail, that is likely due to #2 above.
