A generic sequence matching library, with an additional Harmony-IL-tailored sublibrary.
Reference the Nanoray.Shrike NuGet package in your project.
The NuGet package is compatible with .NET 5+, with some small API changes when using with .NET 7+.
Finding a sequence of uppercase-only, then lowercase-only, then uppercase-only strings in a row, then removing that sequence
ElementMatch<string> uppercase = new("uppercase", e => e.ToUpper() == e);
ElementMatch<string> lowercase = new("lowercase", e => e.ToLower() == e);
IEnumerable<string> newElements = new SequenceBlockMatcher<string>(
"lorem ipsum dolor sit amet",
"THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG",
"oak is strong and also gives shade",
"CATS AND DOGS EACH HATE THE OTHER",
"the pipe began to rust while new"
)
.Find(uppercase, lowercase, uppercase)
.Remove()
.AllElements();IEnumerable<string> newElements = new SequenceBlockMatcher<string>(
"a", "b", "c", "d", "e", "f"
)
.Find(new ElementMatch<string>("c"))
.PointerMatcher(SequenceMatcherRelativeElement.First)
.Advance(2)
.Replace("1", "2")
.AllElements();Finding a sequence of 1-, 2-, 3-, 4-, 5-long strings, anchoring the 3-long element, then removing it and its neighbors

new ElementMatch<string>("2-long", e => e.Length == 2),
