[swift-dev] State of String: ABI, Performance, Ergonomics, and You!

[Omar Charif]

Hi Michael,

I have been doing some research on fast string matching algorithm that I developed recently and I spent some time testing and benchmarking the algorithm and it seems fine so far. It is slightly similar to the one I proposed to Swift 3 or 4 months ago, it is doing some processing first to analyze a big block of text, files or whatever we give it and then it is ready for matching and referencing the results locations etc … I have written a C++ version here https://github.com/o-micron/RootsCLI <https://github.com/o-micron/RootsCLI>

This is mainly reached through some maths approximations to each word so that we can do some sort of hashing to it but not straight hashing … the main idea is to transform the word to a single double, the way this is done is by embedding informations about the order of the letters and the size of the word as a whole

The tests were made with generated file containing permutations of all possible words etc … 

Would like to know your opinion about it.

BR,
Omar
