Jira (PUP-2883) epp does not handle empty template

[Henrik Lindberg (JIRA)]

Title: Message Title

Henrik Lindberg commented on an issue   Re: epp does not handle empty template This also reproduces the problem: notice inline_epp(@(END)) -END {end} The problem occurs because the grammar requires there to be at least one statement in the body (a string to emit, or some puppet _expression_). Thus, this is not a big problem, but the error message is baffling. The grammar should be changed to allow for an empty epp body. If we want to validate that epp actually contains something we can handle that in validation, but it is questionable if that should be done, since the configuration may want the logic to use a template that is different on different branches, and sometimes want the configuration to have a template that is empty. Thus, the fix is to only change the grammar to accept an empty body. Add Comment   Puppet / PUP-2883 epp does not handle empty template When epp is told to evaluate an empty template, the result is a complaint that the end of input is reached. epp should produce an empty string in this situation and not complain. To reproduce: {code} notice inline_epp(@(END), {x => world})   <%-| $x| %>   |- END {code} This template has a parameter, but no other content in the template.
