IDL Parser for C/C++

Single-file header library to parse an International Driver License (IDL).

Barcode

IDLs are usually encoded in a PDF417 barcode. Reading this barcode is not part of this library.

How to use

Before you include the header file in one C or C++ file, you need to define IDL_PARSER_IMPLEMENTATION to create the implementation:

#define IDL_PARSER_IMPLEMENTATION
#include "idlparser.h"

How to parse an IDL

Then invoke parse_idl() with IDL data:

IDL idl;
if (!parse_idl(&idl, data)) {
	fprintf(stderr, "error: failed to parse IDL\n");
	free_idl(&idl);
}

Now the structure idl contains the parsed elements of the IDL:

printf("IIN:[%s]\n", idl.iin);
for (unsigned int i = 0; i < idl.count; ++i) {
	IDLElement *e = idl.elements + i;
	printf("%s:[%s]\n", e->key, e->value);
}
free_idl(&idl);
