NAME¶
Perl::Critic::Policy::InputOutput::ProhibitOneArgSelect - Never write "select($fh)".
AFFILIATION¶
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION¶
Conway discourages the use of a raw "select()" when setting autoflushes. We'll extend that further by simply prohibiting the one-argument form of "select()" entirely; if you really need it you should know when/where/why that is. For performing autoflushes, Conway recommends the use of "IO::Handle" instead.
select((select($fh), $|=1)[0]); # not ok select $fh; # not ok use IO::Handle; $fh->autoflush(); # ok *STDOUT->autoflush(); # ok
CONFIGURATION¶
This Policy is not configurable except for the standard options.
SEE ALSO¶
IO::Handle.
