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.
