text-files sort. e.g. CSV. Example: content: `d,420;b,42;b,21;a;21;c;"42"`, delimiter ';' after sort by prefix: `a:21;b,42;b,21;c:"42";d,420` binary search by prefix `b`: `b,42;b,21`
The project is completed with tests and documentation. It is open source. Github: https://github.com/DataFabricRus/textfile-utils I think there shouldn't be any problems with reading the code. Kotlin - is advanced java, or you can consider it as pseudocode. Perhaps I should supplement the description in `README.md` to make it clearer? Could you please tell me what I should include? Yes, many databases have sorted files under the hood. But what should I do if I need to just search in a big file? I can't reuse database code, I can't make a particular trivial task more complicated by using a database. I haven't been able to find any good solutions in regular libraries. So I invented this bicycle.I think the desire to have such a library is understandable. Please ask any questions.
