Perl::Critic::Policy::InputOutput::ProhibitJoinedReadline
It's really easy to slurp a whole filehandle in at once with join
q{}, <$fh>, but that's inefficient -- Perl goes to the trouble of
splitting the file into lines only to have that work thrown away.
To save performance, either slurp the filehandle without splitting like so:
do { local $/ = undef; <$fh> }
or use the File::Slurp manpage, which is even faster.
Due to a bug in the current version of PPI (v1.119_03) and earlier,
the readline operator is often misinterpreted as less-than and
greater-than operators after a comma. Therefore, this policy only
works well on the empty filehandle, <>. When PPI is fixed, this
should just start working.
Initial development of this policy was supported by a grant from the Perl Foundation.
