Dear fellow monks.

I think that some time ago I have seen somewhere information about a package on CPAN (in a blog post I think), which could be used in testing, and which:

by default failed, when named output file was changed
could run in such a mode, that it would "remember" current state of the file (if the change was intentional), which would prevent further fails (until next change)

Imagine you are programmatically creating complex structured text, and want to be able to "keep it fixed" in you tests - unless you know that the change is "for the better"

Is my memory playing tricks on me? Are you aware of such library? I hope that what I vaguely described above makes sense.

Unfortunately, mu Google-fu is not advanced enough to yield the answer.

Regards, Jan

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
Want more info? How to link or How to display code and escape characters are good places to start.
