Template:Bibcode
 | This template uses Lua: |
 | The link in this template goes to a redirect page instead of to the article that is the target of the redirect. This redirect link is intentional so that links using the template are distinguishable from links to the article on the Special:WhatLinksHere/Bibcode page. |
This template is intended to allow simple standardized links to bibcodes. For example, {{bibcode|1998ApJ...508L..81K}} will produce Lua error in Module:Citation/CS1/Configuration at line 2172: attempt to index field '?' (a nil value). external link.
Usage
This template accepts these parameters:
|idn=– a bibcode identifier; the|idn=parameter name is not required but is recommended for clarity when the template has multiple bibcodes|bibcode-accessn=– accepts a single valuefree; for use when the bibcode at|idn=is free-to-read; enumerators required for second and subsequent bibcode identifiers; bibcode identified sources are assumed to be paywall protected|link=– accepts a single valueno; for use when it is the 'Bibcode:' prefix in the rendering should not be linked|plainlink=– accepts a single valueyes; suppresses the 'Bibcode:' prefix in the rendering|leadout=– defines the conjunction between the last two identifiers in the rendered list; defaults to,
The basic form is:
{{bibcode|place_bibcode_id_number_here}}
Example
{{bibcode|1998ApJ...508L..81K}}→ Lua error in Module:Citation/CS1/Configuration at line 2172: attempt to index field '?' (a nil value).{{bibcode|1927LAstr..41..165F|bibcode-access=free}}→ Lua error in Module:Citation/CS1/Configuration at line 2172: attempt to index field '?' (a nil value).
Error messages
The {{bibcode}} template checks the bibcode value to see if it has the proper format.[1] When the assigned value does not have the proper format, the template returns an error message along with the type of error that is encountered:
- Check bibcode <type>
Bibcode template values are expected to match these requirements:
- length must be 19 characters (<type> = 'length')
- characters in position(s): (except as specified otherwise, violations produce 'value' in the <type> portion of the error message):
- 1–4 must be digits and must represent a year in the range of 1000 – next year (<type> = 'year')
- 5 must be a letter
- 6–8 must be letter, ampersand, or dot (ampersand cannot directly precede a dot; &. (<type> = 'journal'))
- 9 must be letter or dot
- 10–18 must be letter, digit, or dot
- 19 must be a letter or dot
To resolve this error, ensure that the assigned bibcode value is correct.
- ^ Lua error in Module:Citation/CS1/Configuration at line 2172: attempt to index field '?' (a nil value).
