Re: [Haskell-cafe] Hint's setImports usage

Yeah, I've run into that too.. It does seem like there ought to be a better way, but in order to get around that, I just define the imports (or generate) "MyPrelude.hs" in the current directory. That file can just consist of "import OtherPackage.MyPrelude". -Michael On Thu, Dec 20, 2012 at 4:12 PM, Martin Hilbig wrote:

oh that's neat!

but what to do if MyPrelude is provided by some package?

i get this error:

module `MyPrelude' is a package module

and neither

set [languageExtensions := [PackageImports]]

nor

{-# LANGUAGE PackageImports #-}

helps.

Hello!

Try doing this first:

loadModules ["My.Module"]

You may also need to set the "searchPath" - it defaults to the current director. Another good function to know about is "setTopLevelModules", which is just like using ":load" in ghci - it imports everything in the module, including its imports. So, I often do:

loadModules ["MyPrelude"] setTopLevelModules ["MyPrelude"]

And stick all of the things that I want to be in scope into "MyPrelude.hs".

hi,

how to use Language.Haskell.Interpreter._**_setImports?

i use it like:

setImports ["My.Module"]

so that my interpreted modules don't need to:

import My.Module

But i still get:

Not in scope: data constructor `MyType'

What am i doing wrong?

Thanks in advance.
