( [id://3333]=superdoc: print w/replies, xml ) Need Help??
I know you can do this with closures, but I'm wondering if there is a better way. Here is the example:
a(); b(); print "$var\n"; sub a { local $var = "a\n"; c(); } sub b { local $var = "b\n"; c(); } sub c { # i'm pleasing you to print a or b print "var: $var"; }
So you can see, I want c() to have access to the calling sub's my variables. I know that if I eval the creation of that sub in a() or b() it will work, however I don't want to have to do that for every sub that calls c().

Is there a hack to do the above?

If not, here is my next best choice... the sub c() is actually spit out by a class and evaled in the callers package, is it possible to have the eval happen in the callers namespace?

That is:

$b = new SubMaker(); sub a { my $var; $b->make_sub("subname"); subname(); }
where SubMaker::make_sub() evals in the callers namespace so that subname() now has access to $var. Is that possible?

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).
