Parsers for Digital Object Identifiers (DOIs) and Other Identifiers
Uses the R pkg piton which gives access to the C++ PEG implementation PEGTL.

Capture any letter
struct name
: plus< alpha >
{};
Capture any digit
struct numbers
: plus< digit >
{};
Rules are combined to form a grammar,
e.g., string must match name, then have one comma, then one space,
then match numbers.
struct grammar
: must< name, one< ',' >, space, numbers, eof >
{};
Which is then applied to parsing user input strings
- pid_dois
- pid_dois_prefixes
- pid_dois_split
- pid_dois_suffixes
