This seems to be a bug in the weird, custom import subroutine of IO::Prompter because it works when used in the traditional fashion:
perl -e'use IO::Prompter; prompt -menu => [6..9]'
The custom import subroutine takes the second argument given to it as fake input:
# Export the prompt() sub...
sub import {
my (undef, $config_data, @other_args) = @_;
# ...
if( 0 ) { # other options that do not apply
# Handler faked input specifications...
elsif (defined $config_data) {
$fake_input = $config_data;
}
}
I don't understand why @_ is not as expected for it, but the code path triggered is the one for fake input data as in:
perl -e'use IO::Prompter 'fake'; prompt( -menu => [6..9] )'
... which provides the fake input fake.
Right after posting I understand. The custom export subroutine does not take the name of the subroutine to export! Just leaving out the prompt makes things work:
perl -MIO::Prompter -e'prompt -menu => [6..9]'

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>

<sub> <sup> <table>
<td> <th> <tr> <tt>

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).
