brainwash

Description

brainwash project is an open source interpreter for the Brainfuck programming language, written in ANSI C. Implementation-specific details: · The array has no bounds; this makes the pointer able to move towards both left and right "infinitely". · Since each cell holds a signed integer value, cell values can be negative. · Cell values are initialized to 0 (zero). · A cell will assume its minimum/maximum value if it is already at its maximum/minimum value and a + / - command is executed respectively. · Cell values are left intact when executing a , command after the end of input. · Characters other than the eight Brainfuck commands are considered to be comments and are thus ignored. This, with the exception of ! and # that sometimes act as commands and other times dont (comments). · When both the program code and its input are read from stdin, ! is (a command) used to separate them. · When the -d option is used, # is (a command) used to print, to stderr, a memory snapshot of the surrounding cells (useful for debugging). brainwash is distributed under the terms of the 2-clause revised BSD license which is available in its LICENSE file. Installation For gzip: $ tar -xzvf brainwash-0.2.tar.gz For bzip2: $ tar -xjvf brainwash-0.2.tar.bz2 Then: $ cd brainwash-0.2/ $ gcc brainwash.c -o brainwash This will create the brainwash binary under the current working directory. Usage By invoking brainwash with the -h option, the following help message is printed: $ ./brainwash -h brainwash 0.2 (2005-02-05) Usage: ./brainwash [-t] [-d width] [-i file] [-o file] [file | -] ./brainwash -h ./brainwash -V -t Time interpretation. -d width Print the memory snapshot of the width - 1 surrounding cells upon #. -i file Read the input from file. -o file Write the output to file. file Read the program from file. - Read the program from standard input (default). -h Print this help message and exit. -V Print version information and exit. Whats New in This Release: · Licensed under the MIT license. · Standardized the use of temporary files. · Made unsigned character cells possible by issuing `make char` instead of · `make` during installation. · Removed the -t option (not accurate). · Made the argument of the -d option to default to 11 or less. · Made the array finite at the left. · Made the program to ignore a possible shebang line to allow executable · Brainfuck programs. · Implemented optimization (suggested by Jon Ripley) through the -O option..
