A canonical Error type, which provides a way to turn an error string into an Error, add context to an Error, and pretty print the Error for displaying it to users.

Changes

Revision history for error

1.0.0.0 – 2022-10-09

  • No changes, just signify that the library is stable now.

0.3.0.0 – 2022-02-16

  • Add IsString instance for Error.

  • Breaking: Rename addContext to errorContext.

    Since Data.Error is expected to be imported unqualified, addContext was not super obviously related to error handling. errorContext is a lot clearer. This is hopefully the last big breaking change before 1.0.

0.2.1.2 – 2021-11-15

  • Fix doctests.

0.2.1.1 – 2021-11-14

  • Make compatible with GHC 8.0.2 again by not using <&>.

0.2.1.0 – 2021-11-13

  • Add expectErrorIO and unwrapErrorIO.
  • Add ifIOError and ifError.

0.2.0.0 – 2021-10-29

  • Add Show instance to Error.

0.1.1.0 – 2021-10-28

  • Add HasCallStack to expectError and unwrapError.
  • Add showToError and exceptionToError.
  • Improved documentation of existing functions.

0.1.0.0 – 2021-06-26

  • Initial version. More or less feature complete, unless we decide we need extra helper functions.
