The C++ program for efficient comparison of text files. The program implements the Myers algorithm and provides the ability to choose a tokenizer, as well as an output diff format.
This project is a course work of the HSE CS AMI.
Run cmake . and make. The result is executable file diff.

old old file path

-h, --help shows help message and exits
-v, --version prints version information and exits
-p, --parser PARSER_MODE parser mode: bytes, utf-8 [default: "utf-8"]
-t, --tokenizer TOKENIZER_TYPE tokenizer type: symbol, word, line, ignore-all-space, ignore-space-change, semantic-code [default: "line"]
--common-prefix prefix for printing common part in raw mode [default: ""]
--old-prefix prefix for printing deleted part in raw mode [default: "[-]"]
--new-prefix prefix for printing added part in raw mode [default: "[+]"]
-b, --benchmark measure timings
-c, --common print common parts of the files
--raw print diff without colors
--show-common-newlines print common part with newlines displayed as '\n'
--show-pos print diff start position in both files
-r, --recursive recursive directory mode
Use --tokenizer semantic-code option to tokenize code files using Language Sever:
To install all packages for this option, you can run sudo ./setup.sh in you terminal
