The input:
my $foo = $bar;
print "hi $foo\n";
print 'hi ', $foo, "\n";
...stored in very-easy-print-interpolation2.pl
Run, thusly:
ppi_dumper very-easy-print-interpolation2.pl
ppi_dumper is in App-PPI-Dumper.
The output:
PPI::Document
PPI::Statement::Variable
PPI::Token::Word 'my'
PPI::Token::Whitespace ' '
PPI::Token::Symbol '$foo'
PPI::Token::Whitespace ' '
PPI::Token::Operator '='
PPI::Token::Whitespace ' '
PPI::Token::Symbol '$bar'
PPI::Token::Structure ';'
PPI::Token::Whitespace '\n'
PPI::Statement
PPI::Token::Word 'print'
PPI::Token::Whitespace ' '
PPI::Token::Quote::Double '"hi $foo\n"'
PPI::Token::Structure ';'
PPI::Token::Whitespace '\n'
PPI::Statement
PPI::Token::Word 'print'
PPI::Token::Whitespace ' '
PPI::Token::Quote::Single ''hi ''
PPI::Token::Operator ','
PPI::Token::Whitespace ' '
PPI::Token::Symbol '$foo'
PPI::Token::Operator ','
PPI::Token::Whitespace ' '
PPI::Token::Quote::Double '"\n"'
PPI::Token::Structure ';'
This demonstrates that PPI does not handle interpolation in a print statement very well, but a print statement with a list does work.

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).
