I want to take the literal source code of the parameter of a function call, and use it as a string at runtime. (...in a similiar fashion to the # operator in the context of a macro definition in the C/C++ preprocessor.)
sub literalize
{
????
}
sub assert($)
{
my ($condition) = @_;
my $literal_condition_code = literalize(@_);
if ($condition)
{
print "assertion failed: $literal_condition_code\n";
}
}
assert(42 == 24);
Output:
assertion failed: 42 == 24
The C/C++ code would be:
#define assert(condition) { if (!condition) { printf("assertion failed
+: %s\n", #condition); } }
Anyone know how to do something like this in Perl?
Thanks,
Andrew.

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).
