FAQ
I know this may be a stupid posting, because I've touched the topic before.
But I keep running into this problem and I think I remember that you
(Gerald) told that you would fix the problem I reported (rows with <TH>
cells).

I've written some sub routines to handle data list and data entry tables. I
need this construction a lot of the time:

<table>
<tr>
some <th> cells
</tr>
[$if something$]
<tr>
<td> for @data1
</tr>
[$elsif some other thing$]
<tr>
<td> for @data1
</tr>
<tr>
<td> for @data2
</tr>
[$endif$]
<tr>
some fixed rows at the end
</tr>

So obviously I'd like the tags <tr></tr> to be the enclosing entity for
which a recurring action shuld take place. At least as an option.

Another options is of course to program it myself in Perl, but I like to use
the power of the tools I work with, and automatic iteration is one of
Embperls strength.

(Maybe) on another note, I'd like to know more about how to use recipes. Or
rather: For what. Obviuosly it's a very nice solution. But I can't figure
out for which problem. Will I be better off using a recipe than the above
mentioned subroutine components?

Right now I find data in my epl files and then I pass it on together with a
hash containing information about how to display and process the fields to a
subroutine. Getting back from this subroutine I call the update routines.

Will recipes be a better way and if so, why? If not, where can I put recipes
to good use?

    I have put some work into it and found out that it is much more complicated
    than I have expected, but I still plan to implement it. Hopefully it will be
    in 2.0b9, but I can't promise...

    Receipes are basicly good for doing a kind of filtering or transformation of
    the source. The most obvious example is doing XSLT transformation. For
    example you can use a POD files as input (maybe with Perl init), Embperl
    transforms it to XML and then you run an XSLT transformation to get HML. The
    idea is, that you can run other transformation, for example to get PDF (that
    not implemented right now, but I am working on it).

    I am currently updating the website, on thing that is already online is my
    talk of the ApacheCon, which gives you some ideas of receipes and how the
    Embperl website uses them, take a look at
    http://www.ecos.de/embperl/pod/intro/IntroEmbperl2.htm
