I created program that generates brainfuck code that outputs given text.
Arguments for the program are input file with the text and output file where code will be generated to.
Here is the code:



#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define ALLOCATION_ERROR 1
#define FILE_ERROR 2
#define OTHER_ERROR 3

static inline FILE*
get_file_pointer(const char* filename,const char* mode){
FILE* file_pointer=fopen(filename,mode);
if(file_pointer==NULL){
fprintf(stderr,"Error: failed to open file %sn",filename);
exit(FILE_ERROR);
}
return file_pointer;
}
static inline char*
int_to_brainfuck(int difference){
if(difference==0)
return ".";
else{
char character_in_loop=difference>0?'+':'-';
difference=difference>0?difference:-difference;
const unsigned int loop_body_length=17;
const unsigned int number_of_ones=(unsigned int)(difference%10);
const unsigned int number_of_tens=(unsigned int)(difference/10);
char* brainfuck_code=calloc(number_of_tens+loop_body_length+number_of_ones+2,sizeof*brainfuck_code);
if(number_of_tens>0){
brainfuck_code[strlen(brainfuck_code)]='>';
memset(brainfuck_code+strlen(brainfuck_code),'+',number_of_tens);
strcat(brainfuck_code+strlen(brainfuck_code),"[<");
memset(brainfuck_code+strlen(brainfuck_code),character_in_loop,10);
strcat(brainfuck_code+strlen(brainfuck_code),">-]<");
}
memset(brainfuck_code+strlen(brainfuck_code),character_in_loop,number_of_ones);
brainfuck_code[strlen(brainfuck_code)]='.';
return brainfuck_code;
}
}
static inline void
generate_code(FILE* input_file,FILE* output_file){
int current_char,last_char=0;
while((current_char=fgetc(input_file))!=EOF){
char* brainfuck_code=int_to_brainfuck(current_char-last_char);
fputs(brainfuck_code,output_file);
if(brainfuck_code[0]!='.')
free(brainfuck_code);
last_char=current_char;
}
}
static inline void
parse_args(int argc){
if(argc!=3){
puts("Usage: bfgen <input> <output>");
exit(OTHER_ERROR);
}
}
int
main(int argc,char** argv){
parse_args(argc);
FILE* input_file=get_file_pointer(argv[1],"r");
FILE* output_file=get_file_pointer(argv[2],"wb");
generate_code(input_file,output_file);
fclose(input_file);
fclose(output_file);
return 0;
}
