So I'm interested if there are other libraries that are more suitable to the task of generating haskell code for library use, and thus generate 'human readable' exported code (so no TH). I'm also interested in how other projects generate code for their packages.

Since you ask how other packages solve this problem, and since most packages use template haskell, I have to ask: why can't you use template haskell for this?

For my case, template haskell can't create modules, and template haskell solves a different problem - I've not interested in creating Haskell declarations from Haskell declarations - I'm interested in creating Haskell modules from an external, formal, specification. In a sense I'm compiling to Haskell.

Another option (also not code generation, but very useful in reducing boilerplate) is generic programming, for example using the 'regular' package, or the new generics in GHC 7.2.
