Re: [Haskell-cafe] Status of Acid-State and IxSet

Oh, sorry, your mail was from today as well, so github was the upstream, it's been a while since I've been on -cafe and thought this was an older thread. All the best, Andrea On Fri, May 29, 2015 at 10:08 PM, Andrea Vezzosi wrote:

Hello,

acid-state is still alive and kicking (and better be since hackage uses it). In fact, there is a GSoC project to add replication support this summer I believe.

ixset is still supported. We submitted a patch upstream to syb-with-class but have not heard back. Our patched version is here:

Where is this upstream? Since I haven't seen any patches my way until today I guess there's some other place where I'm not checking.

Anyhow there's a new version on hackage now which builds on ghc-7.10.

I would gladly transfer maintainership of syb-with-class though.

Cheers, Andrea

Nix patches syb-with-class by default -- which is nice ;)

If you do not have legacy code to support, I highly recommend checking out ixset-typed. It is very much like ixset -- but does a better job catching errors though the type system. IxSet is a little too loose with the types for no real reason resulting in avoidable runtime errors.

Hello, for a project I decided to use Acid-State and IxSet, and was pretty happy with them. I enjoyed working with Haskell structures for storing and querying data, and my data could fit in memory. However, now I've moved to GHC 7.10, and for example syb-with-class, a dependency of ixset, does not build with template-haskell 2.10. So I'm wondering, are these projects still alive and kicking? Are if I want some memory based storage and indexing, should I look at some other projects (maybe VCache http://hackage.haskell.org/package/vcache). Or is it just bad timing and GHC 7.10 compatible versions of these libraries are in the works?

Thanks!
