Why not just tell them to import your library and do something like <br>> main = withSomeInit labMain<br>where "withSomeInit" is the function you provide? This approach is present in some other libs that require initialization.<br>

<br>
I am trying to write a wrapper library for lab work to give to students.<br>
My problem is, that the libraries I use require initialization that I<br>
really want to hide from our students. The wrapper I'm writing is<br>
compiled to a static library and installed with cabal, so students can<br>
just "ghc --make" or "ghci" their sources. Here comes the problem: I<br>
want to define main and let students just define labMain as an entry<br>
point to their program.<br>
<br>
How can I have my library use "labMain" without a definition? Keep in<br>
mind that I want to give them a cabalized library that they can just<br>
link to, so I can't give them a template file that they fill and compile<br>
together with my code. Is it at all possible to have "external"<br>
functions and letting the linker sort stuff out?<br>
<br>
Regards,<br>
Philip<br>
