Yes, I ported the pretty printer to work with the annotated tree but ignore the annotations.

This sounds good to me, it is pretty awkward to have both representations, especially since they have diverged. It will also help the overlong compile time.

One question: Will you still be able pretty print if you remove the annotations?

Dear all,

For several months I have had a branch of haskell-src-exts which has been updated for all the new features in GHC 8.

However, I have not yet released the changes as in this version I also removed the simplified AST. To those unfamiliar, HSE provides two ASTs, one which has source locations and one which doesn't. I have removed the one which doesn't.

This simplifies maintenance and I think also makes the library easier to use.

I have held back releasing this version as there are some people who use the simplified AST. The changes necessary for the new version are mechanical and easy to make. For example, David Fox updated haskell-names to use my branch [1] with few problems.

The question is, are there any users of the library who object to this change?

Matt

Old versions of HSE only had the un-annotated version so perhaps the annotations were added in separate types to avoid breaking changes. On Sun, Jul 31, 2016 at 1:52 PM, Tom Ellis < tom-lists-haskell-cafe-2013@jaguarpaw.co.uk> wrote:

I haven't been following very closely, but can I ask what the use case was for the one which did not have source locations? Is it just to avoid filling in/ignoring a dummy () parameter when constructing/destructing respectively? _______________________________________________ Haskell-Cafe mailing list To (un)subscribe, modify options or view archives go to: http://mail.haskell.org/cgi-bin/mailman/listinfo/haskell-cafe Only members subscribed via the mailman list are allowed to post.

I'm not sure. I think it was mostly a historical artifact. Originally there was only the simplified AST, at some point the AST was augmented with source locations but the simplified tree was not removed for backwards compatability. Some of the library still operated on the old simpler AST such as the pretty printer but now everything is ported over.

Good work getting rid of the old stuff then!
