unix: Improve baud rate handling. #135
by Travis Whitaker 14 Jan '20

14 Jan '20

Greetings Haskellers, I am writing to draw your attention to https://github.com/haskell/unix/pull/135. The unix library conditionally supports the common baud rate extensions 57600 and 115200. Modern POSIX systems support a much wider set of extensions, and this PR adds additional extended baud rates that have been available on MacOS and Linux for several years. The same CPP mechanism for conditionally enabling these extensions is used. The PR has been open for a few months and I am interested in moving it forward. Thanks for your time, Travis Whitaker

WARNING pragmas in `Prelude.undefined` and `Prelude.error`
by Vilem Liepelt 13 Jan '20

Has there been any discussion about adding WARNING pragmas to `Prelude.undefined` and `Prelude.error`, as done in some custom preludes? I suppose this hasn't been done yet to avoid breaking existing code which makes "legitimate" use of those helpers?

I noticed that issues and PRs on bytestring repository[0] have received no feedback in past 6 months. Does anyone know what's going on? If I can help moving things along, I definitely would like to. [0] https://github.com/haskell/bytestring

Discussion: forM for Data.Set
by hasufell＠posteo.de 12 Jan '20

This was posted a year ago already, but without many comments: https://mail.haskell.org/pipermail/libraries/2019-January/029335.html So after cleaning up the PR a bit, adding tests and benchmarks, let's give it another go. PR is at: https://github.com/haskell/containers/pull/592 New functions are: forM, mapM, for, traverse This follows the other Data.Set exported functions, overwriting Prelude ones like foldr etc, so I think that's exactly what we want. Cheers, Julian Ospald
