Chime<\/a>:<\/p>\n

\n

The code in this repo should be considered Non-Functional<\/strong> right now. You can download<\/a> the currently released version.<\/p>\n

Chime used to be commercial, but is now free<\/a>. It built up some pretty significant cruft over time. In particular, the core UI application architecture is just in a bad state. It is also quite complex to build. So, I've opted to re-implement that core and pull in parts as appropriate. I'll be putting an emphasis on extracting components into packages as I go. A fitting rebirth, I would say.<\/p>\n<\/blockquote>\n\n

There are also some interesting libraries, such as Rearrange<\/a>:<\/p>\n

Rearrange is a collection of utilities for making it easier to work with NSRange<\/code> and NSTextRange<\/code>. It’s particularly handy when used with the Cocoa text system.<\/p>

[…]<\/p>

[RangeMutation<\/code>] is a struct that encapsulates a single change to an NSRange<\/code>. It’s useful for serializing, queuing, or otherwise storing changes and applying them.<\/p>

You can also use this class to tranform individual points or other NSRange<\/code>s. This is handy for updating a set of stored NSRange<\/code>s as text is changed. This might seem easy, but there are a large number of edge cases that RangeMutation<\/code> handles, including mutations that invalidate (for example completely delete) a range.<\/p><\/blockquote>\n\n
