Are you asking for the same thing as described under "Permit qualified exports" on this Haskell Prime page? http://haskell.galois.com/cgi-bin/haskell-prime/trac.cgi/wiki/ModuleSyst em Simon | -----Original Message----- | From: haskell-cafe-bounces@haskell.org [mailto:haskell-cafe-bounces@haskell.org] On Behalf Of | Brian Hulley | Sent: 27 April 2006 02:51 | To: Haskell-cafe | Subject: [Haskell-cafe] Is it possible to export module aliases? | | Hi - | Given some large list of modules which need to be used qualified, I'd like | to be able to make a convenience module that I could use instead, and which | would export all these modules also qualified by an alias, ie: | | module Top | ( module qualified Top.First as First | , module qualified Top.Second as Second | ) where ... | import qualified Top.First | | so that I could then say: | | import Top | | main = do | a <- First.create ... | b <- Second.create ... | | instead of having to always write: | | import qualified Top.First as First | import qualified Top.Second as Second | -- this may be a *very* long list | | in every module that uses the "Top" API. | | The current "workaround" for this problem in the standard libraries seems to | be to always append the module name to the name of the function or type or | constructor (which is unfortunately, like record field names, not local to | the type but that's another story) eg by using createFirst, createSecond | etc, which seems a bit messy to me. | | An alternative is to use the C preprocessor and #include a file containing | all the import declarations, but although "ok", I'd prefer to be able to | express the code organization purely in Haskell itself. | | This must be a very common issue so I'm wondering if anyone else has some | better ideas on how to solve it? | | Thanks, Brian. | | _______________________________________________ | Haskell-Cafe mailing list | Haskell-Cafe@haskell.org | http://www.haskell.org/mailman/listinfo/haskell-cafe
