Module::Load - runtime require of both modules and files


        use Module::Load;

    my $module = 'Data:Dumper';
    load Data::Dumper;      # loads that module
    load 'Data::Dumper';    # ditto
    load $module            # tritto

    my $script = 'some/'
    load $script;
    load 'some/';      # use quotes because of punctuations

    load thing;             # try 'thing' first, then ''

    load CGI, ':standard'   # like 'use CGI qw[:standard]'


CWload eliminates the need to know whether you are trying to require either a file or a module.

If you consult CWperldoc -f require you will see that CWrequire will behave differently when given a bareword or a string.

In the case of a string, CWrequire assumes you are wanting to load a file. But in the case of a bareword, it assumes you mean a module.

This gives nasty overhead when you are trying to dynamically require modules at runtime, since you will need to change the module notation (CWAcme::Comment) to a file notation fitting the particular platform you are on.

CWload elimates the need for this overhead and will just DWYM.


CWload has the following rules to decide what it thinks you want:

If the argument has any characters in it other than those matching CW\w, CW: or CW', it must be a file
If the argument matches only CW[\w:'], it must be a module
If the argument matches only CW\w, it could either be a module or a file. We will try to find CWfile first in CW@INC and if that fails, we will try to find in CW@INC. If both fail, we die with the respective error messages.


Because of a bug in perl (#19213), at least in version 5.6.1, we have to hardcode the path seperator for a require on Win32 to be CW/, like on Unix rather than the Win32 CW\. Otherwise perl will not read it's own CW%INC accurately double load files if they are required again, or in the worst case, core dump.

CWModule::Load can not do implicit imports, only explicit imports. (in other words, you always have to specify expliclity what you wish to import from a module, even if the functions are in that modules' CW@EXPORT)
