Validates (sort of) and formats a bibcode id. | |||
Format for bibcodes is specified here: http://adsabs.harvard.edu/abs_doc/help_pages/data.html#bibcodes | |||
But, this: 2015arXiv151206696F is apparently valid so apparently, the only things that really matter are length, 19 characters | |||
and first four digits must be a year. This function makes these tests: | |||
length must be 19 characters | |||
characters in position | |||
1–4 must be digits and must represent a year in the range of 1000 – next year | |||
5 must be a letter | |||
6–8 must be letter, ampersand, or dot (ampersand cannot directly precede a dot; &. | |||
9 must be letter or dot | |||
10–18 must be letter, digit, or dot | |||
19 must be a letter or dot | |||
