I'm currently working on a pretty-printer for lazy text [1] values, basing the API on the wl-pprint [2] package.
[1]: http://hackage.haskell.org/package/text [2]: http://hackage.haskell.org/package/wl-pprint
In terms of API decisions, there are a few things I'm not sure of and am wondering what other people would prefer:
* Should the SimpleDoc type still be exported? Or should the rendering functions just return a Builder or lazy Text value?
I'm not really sure what you're asking here, but I find BS Builders pretty convenient to work with. A recent release of 'text' includes a Builder type.
* Is the Pretty class wanted/needed? If so, should the individual combinators (int, bool, etc.) be kept or just use "pretty" for everything?
I frequently write a 'Pretty' class when writing complex ASTs, but I have never found it to be a hardship. I prefer using well-named combinators for primitive types.
* Should String values be catered for or just have everything be Text-based?
The OverloadedStrings language extension solves the most common case for wanting to have string-based pretty-printer functions. Antoine
