0.10.014 Mar 2017Breaking2 sources agree

The change in this case are all on private API. This normally wouldn't cause a breaking change as there are extensive tests wrapping all methods. This…

Non-breaking changes:

Changed from fold to for in which resulted in a average 10-20% boost in
performance for all castings using the case module.

Fixes:

Fixed issue with snake case like strings where numbers were incorrectly
permitted to be next to a string e.g. string1 was considered valid when it
should have been string_1. This has been corrected as part of the above
change.

Why is this not 0.9.1?

The change in this case are all on private API. This normally wouldn't cause a
breaking change as there are extensive tests wrapping all methods. This
however doesn't preclude an edge case that hasn't been considered. I've
deemed it safer to call this a 0.x.0 release for that reason.

0.9.010 Mar 2017Breaking2 sources agree

…this will be a breaking change as the new syntax demands to_camel_case("something") .

Breaking changes:

Changed type signature for all casting methods to use &str. This gives the
crate a >10% increase in performance in a majority of conversions. Although
most users only use:
"my_string".to_camel_case()
or
"myString".to_string().to_snake_case()
For those using the to_camel_case("something".to_string()) this will be a
breaking change as the new syntax demands to_camel_case("something").

0.8.18 Mar 20172 sources agree

Fixed singularize issues with /ies/ . Thanks @mthjones

Bugfixes:

Fixed singularize issues with /ies/. Thanks @mthjones
Fixed issue with feature gates which may have caused downstream api
incompatibilities.

0.8.026 Feb 20172 sources agree

Feature gated pluralize, singularize, class_case, table_case, demodulize, and deconstantize. This can be activated by passing --features=lightweight.

New features:

Feature gated pluralize, singularize, class_case, table_case, demodulize, and
deconstantize. This can be activated by passing --features=lightweight. See
README

Possible breaking change:

Feature gated items are on by default, meaning that you'll get the full
version of the crate if you install as normal. See README if you want to use
the lightweight version.
Although the application still passes all tests, substantial portions of the
core of the conversion code have been method extracted and may have caused a
change for some people. Please file an issue if this is a problem for you.

0.7.08 Jan 2017

Added traits for various number types on ordinalize.

New features:

Added traits for various number types on ordinalize.

Possible breaking change:

Fixed issue with Boxes to Box which may cause breakages for some people

Non-breaking change:

Updated dependencies on regex and lazy_static to be the current latest
Changed the way that traits are implemented to use macros. Thus reducing duplication issues seen previously for each type that wanted to implement Inflector
More tests for conversion between different string formats
Better documentation for new users
Cleaned up documentation

Notes:

This is a pre-release for 1.0.0

Resolves issues with pluralize not always correctly pluralizing strings. Thanks, @weiznich!

Fixes:

Resolves issues with pluralize not always correctly pluralizing strings. Thanks, @weiznich!
Resolves issues with silently failing test on table case
Replaces complex code used for is_*_case checks with simple conversion and check equality.

0.2.016 Jan 2016

Fixed doc tests to properly run as rust auto wraps doc tests in a function and never ran the inner function that was defined.

Features:

Added Pluralize
Added Singularize
Added Table case

Fixes:

Fixed doc tests to properly run as rust auto wraps doc tests in a function and never ran the inner function that was defined.
Fixed documentation for kebab case
Fixed several failed tests for various cases which were mainly typos

Breaking changes:

Class case now singularizes strings and verifies that strings are singularized. Those wishing for the old behaviour should remain on the 0.1.6 release.

Fixes:

Refactored code to mostly pass through snake case then be converted to lower the number of moving parts and reduce the complexity for adding a new casting as only snake case would need to be modified to convert to most other cases.

Breaking changes:

This release is slow in contrast to other crates
