Changed

• MSRV bumped to 1.54.0 (see #102)
• Removed the publically re-exported ansi_term::Style. This was never intended for public use. (see #102)

Fixed

• Moved from the unmaintained ansi_term crate to yansi for ANSI terminal escape code support. Thanks to @Roguelazer for reporting and fixing this! (#102, @Roguelazer)

Fixed

• Fixed a panic caused by diffing two str-like values where only the left has a trailing newline - thanks @Michael-F-Bryan for reporting this (#97, @tommilligan)

Changed

• assert_eq compares str-like values without Debug formatting. (#92, @dtolnay)

Added

• Add assert_str_eq for comparing two str-like values without Debug formatting. Thanks to @x3ro for implementing this! (#88, @x3ro)

Fixed

• Ensure license text is included in crate archive - thanks @decathorpe for reporting this (#87, @tommilligan)

Note: As pretty_assertions has in practice had a stable API for several years, this feature release takes the opportunity to increment the version to 1.0.0 instead of 0.8.0. No breaking changes are expected.

Removed

• assert_ne no longer warns if values match using PartialEq but not with Debug. This was noted as no longer being necessary after Rust 1.25 (current MSRV 1.35.0)

Added

• Officially support no_std (thanks to @Luro02 for the report and reviews!). Adds the std and alloc features to the pretty_assertions crate, with std enabled by default (#83, @tommilligan)
• Adds the unstable feature to the pretty_assertions crate, for use with nightly rustc (#81, @tommilligan)
• Add a drop in replacement for the unstable stdlib assert_matches macro, behind the unstable flag - thanks @gilescope for the suggestion! (#81, @tommilligan)

Fixed

• Fix macro hygiene for expansion in a no_implicit_prelude context (#70, @tommilligan)

Fixed

• Fix a bug where multiline changes showed an unhelpful inline diff (#66, @tommilligan)

Changed

• Move from difference to diff for calculating diffs. The exact assertion messages generated may differ from previous versions. (#52, @tommilligan)

For example, the following assertion message from v0.7.0:

Was previously rendered like this in v0.6.1:

Added

• Support for unsized values (#42, @stanislav-tkach)
• Document the Comparison struct, which was previously hidden. This can be used to generate a pretty diff of two values without panicking. (#52, @tommilligan)

Fixed

• Fix some unhygenic macro expansions (#41, @tommilligan)

Internal

• Test Windows targets in CI (#46, @tommilligan)
• Bump ansi_term version to 0.12 (#34, @waywardmonkeys)
• Code health improvements (#34, @waywardmonkeys)
