Following a previous post Best way to sort these strings ? recursive way ? use Parse::RecDescent?,
i want to obtain this output with the right order :
TEX1J desc 'Job Start'
MEX1J desc 'Job 2' Pred TEX1J
MEX2J desc 'Job end' Pred MEX1J, MEX2J
# MEX1J must appear after TEX1J because it depend on TEX1J
# MEX2J must appear after TEX1J and MEX1J
from a hash defined like this:
%hash={
'MEX1J' => {
'desc' => 'Job 2'
'pred' => [TEX1J],
},
'MEX2J' => {
'desc' => 'Job end'
'pred' => [TEX1J,MEX1J],
},
'TEX1J' => {
'desc' => 'Job start'
'pred' => [],
}
}
I think I must use a recursive algorithm but I don't really see how to do it...
Thanks for the answer

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.
