Hi,
I want a module to detect if it was loaded by "require" or "system". Can this be done in elegant way, or just adding and checking different argument passed by the caller?

More info.

I have working programs, where a Perl script, loaded from command line, will later "require" a module, and jump to a subroutine inside the module, and the rest of the package thereafter.

I checked that Perl will run a .pm script from command line, not neccessary have to be .pl.

I want to add to the .pm file more code that will only be executed if loaded from command line or "system" because I want to share most of the code in the module. The functionality of the module should stay as before. So I guess I need an "if statemt" at the beginning to check who was calling, but check what? :(

I am on Windows XP, Active State v5.8.3 built for MSWin32-x86-multi-thread

Thanks.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
