NAME

Perl::Critic::Policy::ValuesAndExpressions::ProhibitLeadingZeros - Write oct(755) instead of 0755.

AFFILIATION

This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

Perl interprets numbers with leading zeros as octal. If that's what you really want, its better to use oct and make it obvious.

    $var = 041;     # not ok, actually 33
    $var = oct(41); # ok

    chmod 0644, $file;                              # ok by default
    dbmopen %database, 'foo.db', 0600;              # ok by default
    mkdir $directory, 0755;                         # ok by default
    sysopen $filehandle, $filename, O_RDWR, 0666;   # ok by default
    umask 0002;                                     # ok by default

CONFIGURATION

If you want to ban all leading zeros, set strict to a true value in a .perlcriticrc file.

    [ValuesAndExpressions::ProhibitLeadingZeros]
    strict = 1
