发帖数: 190 | 1 Can I ask perl to local the module dependent on the command line
argument inptu? such ash
./binperl --module=mod
in the binperl.pl
you can dynamiclly load the module mod and call a function
mod::function()?
Thanks! |

on command line
or if you prefer to do it inside the program, "require" is actually a
function

发帖数: 190 | 5 Thank you very much for your hint.
Didn't figure out how to use require to achieve this goal.
Here is my problem:
./mybinary.pl --module=modA
or
./mybinary.pl --module=modB
I would like to use the symbol in modA or modB conditional on the argument
input.
such as in mybinary.pl:
I'd like:
if $module eq "modA"
require $module;
$module::function() does not work,
The other question is: is there any way to make a alias to $module,
that I can use

发帖数: 6806 | 6 I am not sure how to alias an entire module (I read through the document and
did some test, seems not work). But you can definitely alias a few
functions, such as:
require POSIX;
local *alias::floor = \&POSIX::floor;
alias::floor(0.5);
