Newer versions of the roo gem have marked the
make_tmpdir
method for deprecation. The deprecation notice suggests usingmake_tempdir
inRoo::Tempdir
, but that method is designed for using without a block (and the cleanup mechanism it uses isn't quite as robust as that used byDir.mktmpdir
). Sinceroo-xls
only usesmake_tmpdir
in the block form, I opted to just directly useDir.mktmpdir
. This fixes the deprecation warnings otherwise sent toSTDOUT
byroo
.
