    <p>Hey haskellers and haskellettes, is it possible to load a module functions in a list. in my concrete case i have a list of functions all checked with or</p> <pre><code>checkRules :: [Nucleotide] -&gt; Bool checkRules nucs = or $ map ($ nucs) [checkRule1, checkRule2] </code></pre> <p>i do import checkRule1 and checkRule2 from a seperate module - i don't know if i will need more of them in the future.</p> <p>i'd like to have the same functionality look something like</p> <pre><code>-- import all functions from Rules as rules where -- :t rules ~~&gt; [([Nucleotide] -&gt; Bool)] checkRules :: [Nucleotide] -&gt; Bool checkRules nucs = or $ map ($ nucs) rules </code></pre> <p>the program sorts Pseudo Nucleotide Sequences in viable and nonviable squences according to given rules. thanks in advance ε/2</p> <hr> <p>Addendum: So do i think right - i need:</p> <pre><code>genList :: File -&gt; TypeSignature -&gt; [TypeSignature] chckfun :: (a-&gt;b) -&gt; TypeSignature -&gt; Bool </code></pre> <p>at compile time. but i can't generate a list of all functions in the module - as they most probably will have not the same type signature and hence not all fit in one list. so i cannot filter given list with chckfun.</p> <ul> <li>In order to do this i either want to check the written type signatures in the source file (?) or the inferenced types given by the compiler(?).</li> <li><p>another problem that comes to my mind is: not every function written in the source file might get exported ?</p></li> <li><p>Is this a problem a haskell beginner should try to solve after 5 months of learning - my brain is shaped like a klein's bottle after all this "compile time thinking".</p></li> </ul>

    1. CONot really. You could perhaps generate the import list programmatically from Template Haskell.

    2. COhmm - i had a look at Template Haskell and was quite overwhelmed - could you give me some hints or keywords to look for.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
