According to perlvar, $^S has three states: true, false or undefined. True inside eval, false elsewhere, or undefined if parsing is not finished. This has the effect of $^S always being undef when die occurs in a BEGIN block (or use.) I'm stuck at this point, so I need to find a way around it.
How do I know if my DIE handler is being called within an eval when parsing is not yet complete?
example:
BEGIN {
$SIG{__DIE__} = sub {
die @_ if $^S; # dont mess with eval.
# ...my custom handler code...
exit(0);
}
eval {
die 'another day';
};
if ($@) {
# execution never happens
};
}
eval {
die 'to day good';
};
if ($@) {
# this works
};

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).
