ppm has asked for the wisdom of the Perl Monks concerning the following question:

Hello again,

i asked for the usage of formats and variables. for this topic i got a solution (thx jmcnamara). This was discussed at http://www.perlmonks.org/index.pl?node_id=6364&user=ppm or direct How to route a format into a variable.

But now i have a new problem:

>> (jmcnamara) I wasn't fully sure what you wanted to do with the ~~:

I will format the Information at "Art.nr." and "Bezeichnung" for multiline output ... In the normal format i will do this with ~~ : 

format INHALT =

 @<<<< ^<<<<<<<< ^<<<<<<<<<<<<<<<<<<<<<<<<<< @>>>>>>>>>  @>>>>>>>>>
$menge,$nr,$text,$preis,$summe,
~~     ^<<<<<<<< ^<<<<<<<<<<<<<<<<<<<<<<<<<<<
       $nr,      $text
.

But this doesn't work with the formline example .. there are any solutions?

thx again! ppm

update (broquaint): changed absolute links to a shortcut and a relative link

    I posted an updated solution to this here Re: How to route a format into a variable.

    The reason that ~~ doesn't really work with formline() is explained in perlfunc: 

       formline PICTURE,LIST
           ...

           Note that a format typically does one `formline' per
           line of form, but the `formline' function itself
           doesn't care how many newlines are embedded in the
           PICTURE.  This means that the `~' and `~~' tokens
           will treat the entire PICTURE as a single line.
           You may therefore need to use multiple formlines
           to implement a single record format, just like the
           format compiler.

        I think in your case you should be fine with formats. However, if you have something more complex or would like to split up code and layout, then a templating system might be a good solution, see e.g. a discussion on Text::Template here at PM, with pointers to other templating modules.

    A sidenode: If you want to point to something else in the Monastery, then don't use <a href=...></a>. The problem with that is that some of us access PM through www.perlmonks.com and some through www.perlmonks.org. With a direct link, you loose your logged-in status if you go from com to org - or the other way round.

    Instead use the internal format for linking with [234758|your node] which looks like this: your node. For more explanation on that syntax look here.
