NAME
beef - flexible Brainfuck interpreter SYNOPSIS
beef [OPTIONS] FILE DESCRIPTION
beef is a Brainfuck interpreter written in C. It is written with flexibility and portability in mind: it is not the smallest nor the fastest Brainfuck interpreter on Earth, but it has some options to control his behavior and doesn't suffer most of the limitations which are usually present in Brainfuck interpreters. One of the best features of beef is that it has no limitations on the length of the tape, which is created dinamically, and allows you to move in any direction, even to move an unlimited amount of cells left when you are on the starting cell. beef also allows you to control his behavior in case it reads and EOF from the input stream: see below for a list of available options. OPTIONS
-d Enable debugging. The debugging command # is not part of the Brainfuck language, but it's an useful feature for the programmer, so most interpreters implement it. Debugging is off by default. -e When read an EOF from input, store an EOF in the current cell. This is for compatibility with programs written for other inter- preters; the default behavior is to store a 0 in the current cell when an EOF is read. -n When read an EOF from input, do nothing. This is the default behavior in some other interpreters, so it's supported in beef for com- patibility reasons. The default behavior is to store a 0 on the current cell instead. --version Show the version number and exit successfully. --help Show a short help message and exit with success. EXIT STATUS
beef returns an exit staus of zero on success, or an exit status of -1 if it was unable to perform the requested operation. Please note that no checks are performed on the code: if the code you are trying to run is buggy, beef will run it anyway and the result will probably differ from what you expected. AUTHOR
