2.8.0 - 2024-01-31

Added

  • Weeder now supports GHC 9.8. (#142)

2.7.0 - 2023-08-17

Added

  • Weeder now supports type class instances. Type class instances can be marked as roots with the root-instances configuration option. (#126, #133, #136)
  • Weeder now optionally detects uses of types, excluding type family instances. This can be enabled with the unused-types configuration option. (#132)
  • Weeder's analysis now runs in parallel. This can almost halve execution time when given enough cores. Enabled by calling Weeder with -j X or -N. (#137)
  • --write-default-config flag to write and read a default configuration, if no configuration file is found. (#133)

Changed

  • All configuration options now have default values. This can be disabled with the --no-default-fields flag. (#133)
  • Weeder will now use distinct exit codes for certain failures. See README.md for more details. (#134)

2.6.0 - 2023-07-07

Added

  • Weeder now supports GHC 9.6.

Changed

  • Weeder now uses TOML as a configuration format. Please see Weeder's README for more information on the configuration format.
  • Weeder now sorts weeds in a single file by ascending line number

Fixed

  • Weeder now internally adds declarations once. This shouldn't result in any user visible changes, but may improve performance.

[2.5.0][v2.5.0] - 2023-01-23

  • Weeder has been upgraded to support GHC 9.4 (only). As this changes the format of .hie files accepted, this is a major version bump. Thanks to @tfausak!

2.4.1 - 2023-01-05

  • Build with lens-5.2

2.4.0 - 2022-05-22

  • Weeder has been upgraded to support GHC 9.2 (only). As this changes the format of .hie files accepted, this is a major version bump.

2.3.1 - 2022-05-21

This is the last release of weeder compatible with GHC 9.0.

  • Weeder now analyzes top-level pattern bindings. For example, with the following input:

    module Dep (a, b) where

xxx :: Int
xxx = 3

a, b :: Int
(a, b) = (xxx, 1)

    ... weeder will determine that both a and b depend on xxx. While this is an over-approximation, it prevents weeder from reporting false positives. For more information, see #92.

  • Corrected a typo in --help (#96).

  • Shorten the help text for --require-hs-files (#97).

  • Allow algebraic-graphs-0.6 (#95).

  • Allow Dhall 1.41 (#99).

  • Allow optparse-applicative-0.17 (#100).

2.3.0 - 2021-10-11

  • Switch to GHC 9

2.2.0 - 2021-08-28

This will likely be the last Weeder release before GHC 9.

  • Allow configuration of the HIE file extension using the --hie-extension command-line flag
  • Add --require-hs-files switch. If supplied, this switch means Weeder will only consider .hie files where a corresponding .hs file can be found. (#50)
  • Pattern synonyms are now considered (#79)
  • Weeder's output format is now one-line-per-weed (#62)
  • --hie-extension can be used to change the extension used for .hie files (#64)

2.1.3 - 2020-12-11

  • Support dhall-1.35, dhall-1.36 and dhall-1.37.
  • Support bytestring-0.11.

2.1.2 - 2020-09-09

  • Correctly support optparse-applicative 0.16.0.0. While this was meant to be resolved 2.1.1, 2.1.1 only changed the version for the library and not the executable.

2.1.1 - 2020-09-09

  • Support Dhall 1.34
  • Support optparse-applicative 0.16.0.0

2.1.0 - 2020-06-30

  • Support regex-tdfa ^>= 1.2 (#13)
  • Handle mismatched hie file version explicitly (fixes #8). (#16)
  • Implement --help and --version (#36)
  • Make search directory configurable (#37)
  • Support GHC 8.10

2.0.1 - 2020-03-15

  • PR #7: Support optparse-applicative-0.15.1.0 and algebraic-graphs-0.5. Thanks to @robx for contribuiting this fix!

2.0.0 - 2020-03-15

  • Weeder 2.0 is a ground up rewrite of Weeder using .hie files. It is now maintained by Ollie Charles (@ocharles on GitHub).
