Validates (sort of) 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, digit, ampersand, or dot (ampersand cannot directly precede a dot; &. )
9–18 must be letter, digit, or dot
19 must be a letter or dot

]]

local function bibcode (id)
local err_type;
local year;

if 19 ~= id:len() then
err_type = 'length';
else
year = id:match ("^(%d%d%d%d)[%a][%w&%.][%w&%.][%w&%.][%w.]+[%a%.]$") --
if not year then -- if nil then no pattern match
err_type = 'value'; -- so value error
else
local next_year = tonumber(os.date ('%Y'))+1; -- get the current year as a number and add one for next year
year = tonumber (year); -- convert year portion of bibcode to a number
if (1000 > year) or (year > next_year) then
err_type = 'year'; -- year out of bounds
end
if id:find('&%.') then
err_type = 'journal'; -- journal abbreviation must not have '&.' (if it does its missing a letter)
end
end
end

return err_type;

call this module with:

where {{{1|}}} is the bibcode
