Use custom Matcher to find and replace properties
The simplest way to find and replace properties in Strings is using a
Pattern Matcher. However, implementing a specialized Matcher using
simpler String primitives is faster, so do so using an API that looks
and feels as simple as the Pattern Matcher API.
In a sample walking ancestors use case, this caching and saves a small
but measurable amount of the total time. In the case of a task.config
which walks all dependencies for a change when run with status:open
--no-limit --task--applicable the gain can be seen below.
