Formats and other features added by this plugin.
BibTeX
This plugin adds input and output support for BibTeX,
both in text form and as a JSON representation. Input types are called @bibtex/text
and @bibtex/entry+object, output format is bibtex. The output has format
dictionary support.
BibLaTeX
This plugin adds input and output support for BibLaTeX,
both in text form and as a JSON representation. Input types are called @biblatex/text
and @biblatex/entry+object, output format is biblatex. The output has format
dictionary support.
Bib.TXT
This plugin adds input and output support for Bib.TXT,
a simplified and modernised version of BibTeX. Input types are called @bibtxt/text
and @biblatex/entry+object, output format is bibtxt. The output has format
dictionary support.
Configuration
Configuration can be accessed like the following:
const { plugins } = require('@citation-js/core')
const config = plugins.config.get('@bibtex')| Property | Values [default] | Description |
|---|---|---|
config.parse.strict |
true, [false] |
When true, entries are checked for required fields. |
config.parse.sentenceCase |
'always', 'english', ['never'] |
Convert titles to sentence case when parsing. |
config.format.useIdAsLabel |
true, [false] |
Use the entry ID as the label instead of generating one. |
config.format.checkLabel |
[true], false |
Remove unsafe characters from the provided label (or ID). |
config.format.asciiOnly |
[true], false |
Escape or remove non-ASCII characters. |
Type mappings
Entry type mappings between BibLaTeX or BibTeX and CSL-JSON are available through
config.types.biblatex and config.types.bibtex. In both cases, the Bib(La)TeX
mappings are in the source field and the reverse mappings in the target field.
config.types.biblatex.source.inproceedings = 'paper-conference'
config.types.biblatex.target['paper-conference'] = 'inproceedings'Required types
The list of required fields for each type for BibLaTeX and BibTeX is available
under config.required.biblatex and config.required.bibtex respectively. In
both cases, the list consists of strings for required fields and arrays for sets
of fields where at least one should be present (year OR date for BibLaTeX for
example).
config.required.biblatex.book = [
'title',
['author', 'editor'],
'publisher',
['year', 'date']
]Field types
Field types (used for both BibLaTeX and BibTeX) are available through config.constants.fieldTypes.
This returns an object mapping Bib(La)TeX field names to an array containing a
field type and a value type. The former is either field, list (" and "-delimited),
or separated (comma-delimited). As for the latter:
| Value type | Description |
|---|---|
literal |
Normal text or numeric content |
title |
Like literal but can be affected by config.parse.sentenceCase |
name |
A personal or organizational name |
date |
An EDTF Level 1 date |
verbatim |
Unaltered text (no expansion of commands, etc.) |
uri |
Same as verbatim but if needed the URL is encoded |
| other | No special behaviour, treated like literal |
// Add `daturl` for dat:// URLs
config.constants.fieldTypes.daturl = ['field', 'uri']
// Do not treat `publisher` as a list
config.constants.fieldTypes.publisher = ['field', 'literal']Unicode
config.constants.diacriticsmaps commands (\") to diacriticsconfig.constants.commandsmaps commands (\textinterrobangdown) to general unicode characters (⸘)config.constants.ligaturesmaps non-command character sequences (---,~, etc.) to their replacements (emdash, no-breaking space, etc.)config.constants.ligaturePatternis a RegExp that recognizes the ligatures mapped aboveconfig.constants.mathScriptsmaps superscript and subscript (in properties^and_respectively)
config.constants.diacritics['"'] = '\u0308'
config.constants.commands.textinterrobangdown = '⸘'
config.constants.ligatures = {
'---': '\u2014',
'~': '\u00A0'
}
config.constants.ligaturePattern = /---|~/g // Don't forget the (g)lobal flag
config.constants.mathScripts = {
'^': { '1': '¹' },
'_': { '1': '₁' }
}Formatting
config.constants.formattingEnvsmaps environment commands to formattingconfig.constants.formattingCommandsmaps regular commands to formattingconfig.constants.mathScriptFormattingmaps^and_to resp. super- and subscriptconfig.constants.formattingmaps formatting to HTML (though RTF or Markdown could be substituted)
config.constants.formattingEnvs.bf = 'bold'
config.constants.formattingCommands.textbf = 'bold'
config.constants.mathScriptFormatting['^'] = 'superscript'
config.constants.formatting = {
bold: ['<b>', '</b>'],
superscript: ['<sup>', '</sup>']
}Other commands
The object config.constants.argumentCommands maps command names to functions
handling them. This does not include commands used above. Braced arguments are
parsed automatically based on how many arguments the function takes. It does not
support optional arguments (i.e. those in square braces) yet.
config.constants.argumentCommands.href = function (url, displayText) {
// Note: <a> tags are not supported by CSL so watch out if you use this
return `<a href="${url}">${displayText}</a>`
}
// You can also use it to replace commands that produce text
config.constants.argumentCommands.LaTeX = () => 'LaTeX'English languages
The array config.constants.sentenceCaseLanguages affects which languages are
eligible for sentence-casing when config.parse.sentenceCase is set to 'english'.
All entries should be lowercase.
config.constants.sentenceCaseLanguages = [
'english',
'en-us',
'en-gb'
]Replacement strings
The object config.constants.defaultStrings determines which strings are defined
by default.
config.constants.defaultStrings.larsgw = "Willighagen, Lars G"
