| Summary : Perl module that imports environment variables as scalars or arrays
|
Description :
Perl maintains environment variables in a special hash named \'%ENV\'. For
when this access method is inconvenient, the Perl module \'Env\' allows
environment variables to be treated as scalar or array variables.
The \'Env::import()\' function ties environment variables with suitable names
to global Perl variables with the same names. By default it ties all
existing environment variables (\'keys %ENV\') to scalars. If the \'import\'
function receives arguments, it takes them to be a list of variables to
tie; it\'s okay if they don\'t yet exist. The scalar type prefix \'$\' is
inferred for any element of this list not prefixed by \'$\' or \'AATT\'. Arrays
are implemented in terms of \'split\' and \'join\', using
\'$Config::Config{path_sep}\' as the delimiter.
After an environment variable is tied, merely use it like a normal
variable. You may access its value
AATTpath = split(/:/, $PATH);
print join(\"\
\", AATTLD_LIBRARY_PATH), \"\
\";
or modify it
$PATH .= \":.\";
push AATTLD_LIBRARY_PATH, $dir;
however you\'d like. Bear in mind, however, that each access to a tied array
variable requires splitting the environment variable\'s string anew.
The code:
use Env qw(AATTPATH);
push AATTPATH, \'.\';
is equivalent to:
use Env qw(PATH);
$PATH .= \":.\";
except that if \'$ENV{PATH}\' started out empty, the second approach leaves
it with the (odd) value \"\':.\'\", but the first approach leaves it with
\"\'.\'\".
To remove a tied environment variable from the environment, assign it the
undefined value
undef $PATH;
undef AATTLD_LIBRARY_PATH;
