How can I conditionally use a module in Perl?


Tag : perl , By : Tony Z

I hope this helps . You might find the if module useful for this.
Otherwise the basic idea is to use require, which happens at run-time, instead of use, which happens at compile-time. Note that '
BEGIN {
    my $module = $condition ? $Module1 : $Module2;
    my $file = $module;
    $file =~ s[::][/]g;
    $file .= '.pm';
    require $file;
    $module->import;
}
my @array = do {
    no strict 'refs';
    @{ ${ "${Module}::Array_inside_module" } };
};

How to get function names from compiled Python module without importing it?

With these it helps For C extensions, you have no other option but to import them and use introspection.
Komodo's CodeIntel used separate datafiles generated from a module (using introspection) or otherwise written manually to provide it with autocompletion metadata for C extensions, for example. Their autocompleter then uses this static data instead.

Python importing compiled functions

help you fix your problem Run the recompile script provided in the package. The libraries are compiled for the system the original author was using and are not portable across systems. You might need to update the call of f2py to point to the correct version for your use.

silence warnings about unused variables/functions at the point of their conditionally compiled usage

fixed the issue. Will look into that further So, you want to "lie" to the compiler that you're using a function which you're not actually calling. So how to use a piece of code without executing it?
It seems that the only thing that works on all popular compilers is a C++11-only solution - a lambda which is never called:
#define CHECK(x) [&](){ ((void)(x)); }
#define CHECK(x) sizeof(x)

Dynamically importing a module that is specified at runtime from a compiled output

should help you out Although I don't have direct answer to your question, let me comment on some details.
Using importlib would be the easiest choice I believe. Once you've imported such a generated module on the top of the file, it's clearly obvious wether you've loaded it successfully or not.
