Well I don't know cuz you didn't show the real problem you are trying to solve and the assosiated code.

pod2html() function from Pod::Html uses implicit inputs and outputs.
It could have been pod2html($fh_pod_input, $fh_html_output).

But it is not, and hence my problem.
I want to feed text from a scalar variable to a subroutine that reads from STDIN. Specifically, I want to convert some pod text from a scalar variable to a html file, using Pod::Html::pod2html.

This here does the job, but it uses a script pod2html.pl that wraps the sub Pod::Html::pod2html:

sub string2Html {
    my ($htmlfilename, $podtext) = @_;
    open PIPE, "| pod2html --outfile $htmlfilename"; 
        # works, because there is a pod2html.bat
    print PIPE $podString;
    close PIPE;
}

I would like to replace it by something like this, not using a separate script and pipes or temporary files:

sub string2Html {
    my ($htmlfilename, $podtext) = @_;
    ### some code that causes pod2html to read from scalar \$podtext;
    ### when it wants to read from STDIN
    Pod::Html::pod2html "--outfile $htmlfilename";
    ### code to wrap up 
}

I hope that this clarifies what I am trying to solve.

• 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).
