basesystems change log:

Major release 1.1

Version 1.1.0.0 (05-17-2026)

Cabal

• Upgrade major versions for text and containers versions.
• Add tested-with line for GHC 9.6.7.
• Remove the Dev flag.

Builds / CI

• Use ghcup to install the correct Haskell tooling instead of outdated cabal-install package in all CI scripts.
• Combine documentation generation and packaging into a single script that uploads everything to a candidate hackage page.
• Add script for running the ipfshs unit testing package for basesystems.

Data.BaseSystem module changes

• Both encoder and decoder now use ShortByteString as input/output instead of ByteString. Also encoder and decoder now use Text as input/output data instead of String.

Data.BaseSystem.Alphabet module changes

• This module now exports the defined Alphabet structs.
• Alpha.Symbol is now a plain Char.
• Alpha.Value is now Word32.

New modules

• Data.BaseSystem.Strict is where the basesystem encoders and decoders used for strict ByteString typed data got moved to.
• Data.BaseSystem.Lazy provides basesystem encoders and decoders for LazyByteString data.
• Data.BaseSystem.DigitSystem now provides the instances for used for BaseSystem.
• Data.BaseSystem.BinaryTranscoder provides a unified type-class interface for working with bytestring data and converting to and from bit data for numeric values. This module is likely to become its own package in the future.
• Data.BaseSystem.DigitTranscoder provides generic encoders and decoders for BinaryTranscoder derivied types.

Deleted modules

• Data.BaseSystems got replaced by Data.BaseSystem.DigitSystem.
• Data.BaseSystem.Alphabets got merged with Data.BaseSystem.Alphabet.

Major release 1.0

Version 1.0.0.1 (04-01-2026)

This version aims to fix the issues with the hackage page and provide CI via sourcehut builds.

• Set correct PVP bounds for cabal dependencies.
• Added CI/CD for builds.sr.ht:
  • Add .builds/nudge-parents.yml to automatically update this submodule in other sourcehut repositories.
  • Add .builds/upload-candidate-docs.yml to generate and upload documentation to Hackage.
  • Add .builds/upload-candidate-package.yml to generate and upload a package candidate to Hackage.

Version 1.0.0.0 (03-12-2026)

Finally initialize this package! This version introduces the package to the Hackage repository and the provides an interface for encoding/decoding digit strings in several common numeric basesystems. Namely, this version provides the following modules for processing this data:

Data.BaseSystem

Provides the type-class for BaseSystem and the encoder and decoder methods and generic implementations for 2 kinds of basesystems:

• RadixSystem for typical basesystems such as base10
• BitwiseSystem for special basesystems such as base64 and base32

Data.BaseSystems:

Defines common basesystems using the definitions found in Data.BaseSystem.Alphabets. See the project source code for the names of currently provided implementations.

Other modules:

• Data.BaseSystem.Alphabet data structure definition for basesystem digit alphabets and methods for querying alphabet information.
• Data.BaseSystem.Alphabets definitions for specific digit alphabets for implementing basesystems.
• Data.BaseSystem.Internal provides useful methods used across modules. For example the packInteger and bytesToInteger provides ways to convert Integers to ByteString and vice-versa, which is handy for GHCi and unit tests (so that we don't have to write numbers as ByteStrings before using the encoders or decoders).
