Since the current version of VMD has been drastically changed to make it easier to use VMD functionality this section details equivalent functionality for previous version 1.7 VMD macros.
The changes in functionality involve the parsing of sequences. The equivalent to all the V1.7 functionality, which looks for various data types at the beginning of a sequence, is encompassed by the V1.8 macro BOOST_VMD_ELEM(0,sequence,...), where '0' is the first sequence element and 'sequence' is the sequence, with its optional parameters.
V1.7
BOOST_VMD_IDENTIFIER(sequence,keys,...) looked for an identifier at the beginning of a sequence and returned a 2-element tuple, where the first element is the matching index starting with 1, or 0 if no identifier is found, and the second tuple element is the rest of the sequence or emptiness if no identifier is found.
V1.8 equivalent
BOOST_VMD_ELEM(0,sequence,(identifiers),BOOST_VMD_TYPE_IDENTIFIER,BOOST_VMD_RETURN_AFTER,BOOST_VMD_RETURN_INDEX) returns a 3-element tuple where the identifier found is the first tuple element, the rest of the sequence is the second tuple element, and the matching index, starting with 0, is the 3rd tuple element. If no identifier is found all elements of the returned tuple are empty.
V1.7
BOOST_VMD_BEGIN_IDENTIFIER(sequence,keys,...) looked for an identifier at the beginning of a sequence and returned the matching index starting with 1, or 0 if no identifier is found.
V1.8 equivalent
BOOST_VMD_ELEM(0,sequence,(identifiers),BOOST_VMD_TYPE_IDENTIFIER,BOOST_VMD_RETURN_INDEX) returns a 2-element tuple where the identifier found is the first tuple element and the matching index, starting with 0, is the 2nd tuple element. If no identifier is found both elements of the returned tuple are empty.
V1.7
BOOST_VMD_AFTER_IDENTIFIER(sequence,keys,...) looked for an identifier at the beginning of a sequence and returned the rest of the sequence or emptiness if no identifier is found.
V1.8 equivalent
BOOST_VMD_ELEM(0,sequence,(identifiers),BOOST_VMD_TYPE_IDENTIFIER,BOOST_VMD_RETURN_ONLY_AFTER) is the exact equivalent.

V1.7
