I want to write a module such that I can do this with a certain file:
use MyModule;
my $reader = MyModule->new();
### MyModule opens a file behind the scenes
while(my $line = $reader->get_next_line()){
print "here's the next line: $line\n";
}
### stop when we get to the end of the file, obviously
That is, keep the file handle open in the module and each time I call get_next_line() get one more line.
Clearly I can't keep re-opening the file every time. Do I use a module like Tie::File?
Thanks in advance.

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).
