pxqr / base32-bytestring

Efficient base32 codec for bytestrings.

base32-bytestring is efficient base32 and base32hex codec for bytestrings. The API is similar to base16-bytestring and base64-bytestring packages.

base32-bytestring's Issues

bytestring-0.2.1.0 test suite failure on Linux/i686

Please see http://hydra.nixos.org/build/25451886/log/raw for a complete build log. Unfortunately, the test suite doesn't print much diagnostics.

Get rid of `bits-extras` dependency

bits-extras package uses gcc intrinsics, find more portable way to do byteswapping.

Add support for lazy bytestrings

Add Data.ByteString.Base32.Lazy module providing encode and decode functions for lazy bytestrings.

This package does not build with GHC 9.4.8.

Error: cabal: Failed to build base32-bytestring-0.2.1.0.

what should happen

Running cabal build should build the package.

discussion

The reason for this error is that the parsing of @ has become white space sensitive, I think since the proposal ghc-proposals/ghc-proposals#229, so in this case white space about the @ needs to be cut away.
