Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSuUser(Contributed Perl DocumPerl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr(3)
NAME
Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr - Use 4-argument "substr" instead of writing "substr($foo, 2, 6) = $bar".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Conway discourages the use of "substr()" as an lvalue, instead recommending that the 4-argument version of "substr()" be used instead.
substr($something, 1, 2) = $newvalue; # not ok
substr($something, 1, 2, $newvalue); # ok
The four-argument form of "substr()" was introduced in Perl 5.005. This policy does not report violations on code which explicitly
specifies an earlier version of Perl (e.g. "use 5.004;").
CONFIGURATION
This Policy is not configurable except for the standard options.
SEE ALSO
"substr" in perlfunc (or "perldoc -f substr").
"4th argument to substr" in perl5005delta
