# bencoder: A parser for BitTorrent .torrent files
## Installation
- Go to the [latest release](https://github.com/AaravMalani/bencoder/releases/latest)
- Download the RPM file for Red-Hat based Linux Systems, DEB file for Debian based systems or the DLL or LIB file for Windows
```sh
# Ubuntu/Debian
sudo dpkg -i .deb
# RedHat Based Linux
sudo rpm -i .rpm
```
For Windows, you have to link it into the Visual Studio Project using the Linker menu in the Properties of the Project.
Then download the [`bencoder.h`](https://raw.githubusercontent.com/AaravMalani/bencoder/main/include/bencoder.h) file and include that as a header file.
## Usage
```c
#include
char* bencodeTypes[4] = {
"INTEGER", // data = long long* (A pointer not a constant value)
"STRING", // data = char*
"LIST", // data = struct BencodeStructure* (contiguous structs not to be confused with array of pointers)
"DICTIONARY" // data = struct BencodeMap* (contiguous structs not to be confused with array of pointers)
};
int main(int argc, char **argv)
{
if (argc != 2){
printf("Usage: %s \n", argv[0]);
return 1;
}
// Load file
FILE *f = fopen(argv[1], "r");
if (f == NULL)
{
perror(argv[1]);
return 1;
}
fseek(f, 0, SEEK_END);
size_t fsize = ftell(f);
rewind(f);
char *data = malloc(fsize);
fread(data, fsize, 1, f);
fclose(f);
// Parse bencode
struct BencodeStructure* struc = parseBencode(data, fsize);
free(data);
if (!struc) // Error
{
printf("Error parsing file\n");
return 1;
}
printf("Type: %s\n", bencodeTypes[struc->type]);
freeBencode(struc);
}
```
