# Changelog
This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## v0.3.0-rc.0
### Breaking changes
* `auto_assert` now uses `<-` when comparing against falsy values instead of `==`. Support for comparisons using `==` has been removed.
### Enhancements
* Add [`auto_assert_receive`](https://hexdocs.pm/mneme/Mneme.html#auto_assert_receive/2) and [`auto_assert_received`](https://hexdocs.pm/mneme/Mneme.html#auto_assert_received/1).
* Add [`auto_assert_raise`](https://hexdocs.pm/mneme/Mneme.html#auto_assert_raise/3).
* Existing auto-assertions will now run even when `Mneme.start()` is not called, but new auto-assertions will fail ([#32](https://github.com/zachallaun/mneme/issues/32)).
* Generate patterns for ranges will now use `..` and `..//` syntax instead of `%Range{}`.
### Fixes
* Fix a configuration precedence bug that caused options set in application config to always override options local to the test module, describe block, or test.
* Fix a confusing diff result that could occur with some binary operations ([#11](https://github.com/zachallaun/mneme/issues/11)).
* Don't display preceding comments in diffs ([#26](https://github.com/zachallaun/mneme/issues/26)).
* Fix a number of diffing errors related to structs.
* Fix a compatibility issue with Ecto ~> 3.9.4 ([#34](https://github.com/zachallaun/mneme/issues/34)).
### Notes
* Upgrade to Elixir v1.14.4 or later to fix a diff syntax highlighting bug related to escaped string interpolations ([#30](https://github.com/zachallaun/mneme/issues/30)).
## v0.2.7 (2023-03-29)
### Fixes
* Fix a crash related to escaped string interpolation characters ([#29](https://github.com/zachallaun/mneme/issues/29)).
## v0.2.6 (2023-03-27)
### Enhancements
* Auto-assertion prompts can now be skipped (`s`) in addition to accepted (`y`) or rejected (`n`). This allows the test clause to continue so that later assertions might be run, but fails the test run once the suite finishes.
* Updated formatting for semantic diffs:
* Diffs will be displayed side-by-side if terminal width allows. To always display diffs stacked, use the `diff_style: :stacked` option; see the "Configuration" section of the `Mneme` module doc for more.
* Both `:stacked` and `:side_by_side` diffs have updated, more consistent formatting.
### Fixes
* Don't overwrite test files if their content changes after starting the test run ([#23](https://github.com/zachallaun/mneme/issues/23)).
* Fix a crash that occurred when a value contained nested strings with newlines, e.g. `{:ok, "hello\nworld"}` ([#25](https://github.com/zachallaun/mneme/issues/25)).
* The `j/k` options will no longer be rendered when prompting if there is only a single pattern option.
## v0.2.4, v0.2.5 (2023-03-25)
### Fixes
* Remove unnecessary files from Hex package. This cuts the package size down drastically.
## v0.2.3 (2023-03-25)
### Fixes
* Fix diffing for certain sigil variations.
* Fix `dbg`-related error when running `MIX_ENV=test iex -S mix` ([#20](https://github.com/zachallaun/mneme/issues/20)).
* Fix ETS-related error when calling `Mneme.start/1` multiple times ([#20](https://github.com/zachallaun/mneme/issues/20#issuecomment-1483878101)).
## v0.2.2 (2023-03-20)
### Fixes
* Disable a semantic diffing optimization that caused poor diff results in certain cases, usually manifesting as incorrect branches being compared.
## v0.2.1 (2023-03-19)
### Enhancements
* More consistent formatting between `:semantic` and `:text` diffs.
## v0.2.0 (2023-03-18)
### Breaking
* Mneme now requires Elixir v1.14 or later.
### Enhancements
* Adds semantic diffs which selectively highlight only meaningful changes when updating an assertion. This can be disabled with the `diff: :text` option; see the "Configuration" section of the `Mneme` module doc for more.
### Fixes
* Invalid options now cause a warning instead of crashing test process.
* Internal errors now show an error instead of crashing test process.
* Fix bug causing multiple identical choices to be presented in some cases where empty lists were a part of the value.
## v0.1.6 (2023-03-04)
### Enhancements
* Improved compile-time error message when `auto_assert` is used outside of a `test` block ([#9](https://github.com/zachallaun/mneme/issues/9)).
## v0.1.5 (2023-02-25)
### Enhancements
* More consistent handling of charlists: lists of integers will now generate themselves as a pattern as well as a charlist if the list is ASCII printable ([#6](https://github.com/zachallaun/mneme/issues/6)).
## v0.1.4 (2023-02-23)
### Fixes
* Fix a bug that could cause `auto_assert` expressions to revert to the previous value when using `Mneme.start(restart: true)` ([#7](https://github.com/zachallaun/mneme/issues/7)).
## v0.1.3 (2023-02-22)
### Enhancements
* Add a `:default_pattern` configuration option for auto-assertions which controls the pattern that should be selected by default when prompted.
### Fixes
* When converting an auto-assertion to an ExUnit assertion, select the identical pattern when the `:default_pattern` is `:infer` (set by default).
## v0.1.2 (2023-02-21)
### Enhancements
* Add a `:restart` option to `Mneme.start/1` to restart Mneme if called multiple times.
## v0.1.1 (2023-02-20)
### Enhancements
* Dramatically reduce the performance gap between `auto_assert` and ExUnit's `assert`.
## v0.1.0 (2023-02-19)
First release.
