Use it with `etbi\nFILE', or run one of the built-in examples with `etbi -e NAME'. You\ncan always get help with `etbi --help'.\n\netbi also features an interactive REPL-like (Read Eval Print Loop)\nmode, which you can access using `etbi -i'. In the interactive mode\nyou can easily test snippets of brainfuck code, after which the new\nstate of the tape is shown for easy debugging. The interactive mode\nfeatures a few other modes, which you can see by typing `!help'.\n\netbi implements a few simple optimizations:\n- Movement contraction: multiple movement instructions following\n  each other are added together to one instruction with an argument.\n- Alteration contraction: multiple alteration instructions following\n  each other are added together to one instruction with an argument.\n- Clear loop optimization: loops which can only end with the current\n  cell ending up empty such as '[-]' are converted to a single clear\n  instruction which sets the current cell to 0.\n- Scan loop optimization: loops which are scanning all cells in a\n  direction until they find one set to 0, such as '[\u003e]' are converted\n  to a single instruction which uses memchr or memrchr to find one\n  faster.\n\nTo install etbi simply run `./configure \u0026\u0026 make \u0026\u0026 sudo make install'.\n\netbi is licensed under the GPLv3+, see `COPYING' for the full license\ntext.","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjchmrt%2Fetbi","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjchmrt%2Fetbi","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjchmrt%2Fetbi/lists"}
