Hello Monks,
The following is a working perl script (progA.pl):
#!/usr/bin/perl -P
use strict;
#define C 10
my $var = C;
print $var . "\n";
However, if I include that in another perl file as a library, it no longer works:
#!/usr/bin/perl -P
require "progA.pl";
The problem is that the preprocessor (notice the -P switch) isn't processing included library files. Is there any way to make the preprocessor process included files?
Jim
Update: This is a contrived example. I simplified it for this forum to isolate the problem, which is the fact that the preprocessor ignores included library files. In reality, I have several perl library files which I created, and I want subroutines in those files to be able to call the same subroutine messageLog() and have it behave differently based on which file it was called from (so I can turn off/on message logging from a specific file). I don't know if I can do that with Perl syntax, but I know I can do it with macros: just define the macro for messageLog() at the beginning of each file.

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).
