Cite as you Write

PSA: as of Zotero 5.0.71, access to the CAYW URL will no longer work from the browser for security reasons; curl and other programmatic access such as from editors access will work.

Good news for TeXnicians and those down with Mark (aka Markdown, RST, whatnot): this is the time to go pester the author of your favorite editor for Zotero integration!

Editor integration

vim

Graciously supplied by David Lukes:

paste it in your .vimrc (and modify to your liking):

function! ZoteroCite()
  " pick a format based on the filetype (customize at will)
  let format = &filetype =~ '.*tex' ? 'citep' : 'pandoc'
  let api_call = 'http://127.0.0.1:23119/better-bibtex/cayw?format='.format.'&brackets=1'
  let ref = system('curl -s '.shellescape(api_call))
  return ref
endfunction

noremap <leader>z "=ZoteroCite()<CR>p
inoremap <C-z> <C-r>=ZoteroCite()<CR>

This inserts the citation at the cursor using the shortcut ctrl-z (in insert mode) or <leader>z (in normal, visual etc. modes, <leader> being backslash by default).

Alternatively, if you use a recent version of Vim (not Neovim) and have written your config file in vim9script, you may be interested in a vim9script version of the above solution to take advantage of JIT compilation:

def g:ZoteroCite(): string
    # Pick a citation format based on the filetype (feel free to customize)
    var format: string
    if &filetype =~ '.*tex'
      format = 'cite'
    else
      format = 'pandoc'
    endif

    # Make the BetterBibTeX API call and return the result.
    var api_call = 'http://127.0.0.1:23119/better-bibtex/cayw?format=' .. format .. '&brackets=1'
    var citation = system('curl -s ' .. shellescape(api_call))
    return citation
enddef

inoremap <C-x><C-z> <C-r>=g:ZoteroCite()<cr>

In this case, the keybinding Ctrl-X Ctrl-Z in insert mode inserts a Zotero citation. You can add a normal-mode keybinding in the same way as for the legacy VimScript version provided above.

emacs

@newhallroad wrote a function in elisp, which brings up the CAYW input, adds the chosen items as pandoc citations to the buffer, and moves the point to after the citations. This is for markdown-mode. Emacs users who use org-mode may (or may not) need something different.

(defun alk/bbt-zotero-insert-key ()
  "Run shell command to bring up better bibtex cayw input and insert pandoc citation at point"
  (interactive)
  (shell-command "curl -s http://127.0.0.1:23119/better-bibtex/cayw?format=pandoc^&brackets=true" t nil) ; caret escapes ampersand 
  (search-forward "]") ; place cursor after inserted citation
  )

Zotero Citations for Atom

A sample implementation of real integration (rather than the working-but-clunky workarounds using paste) can be found in the Zotero Citations package for the Atom editor.

VS Code Citation Picker for Zotero

If you don’t feel like typing citations out (and let’s be honest, you don’t), executing VS Code Citation Picker for Zotero extension for the VS Code editor will call up a graphical picker which will insert these for you, formatted and all.

Scrivener 2.0/Marked 2 for Mac

Dave Smith has gracefully written instructions on how to set up Scrivener 2.0 and Marked 2 for OSX to use the CAYW picker, including ready-to-run apps

Scrivener 1.0 for Windows

Emilie has writen instructions for using the CAYW picker for Scrivener 1.0 in Windows 10, with the necessary files

Linux

• Emma Reisz has gracefully written instructions and scripts for setting up CAYW on Linux.
• ConorIA has more versatile solution called zotero4overleaf, which was inspired by Emma’s scripts. This should allow use with Overleaf, which is pretty insane that it’s possible if you think about it.

Overleaf

David Lukes takes Overleaf integration one step further with a GreaseMonkey/TamperMonkey userscript which not only allows popping up the CAYW picker straight from your browser, no other tools required, but adds a hotkey to refresh your bib file on Overleaf. This should work with the free subscription, no fiddling with git or dropbox required.

DIY

BBT exposes an URL at http://127.0.0.1:23119/better-bibtex/cayw ¹. The url accepts the following URL parameters:

The following formats are available:

• natbib. Generates natbib citation commands. Extra URL parameters allowed:
  • command: the citation command to use (if unspecified, defaults to cite)
• latex and cite are aliases for natbib with the assumption you want the cite command to be cite
• citep and citet are aliases for natbib with the assumption you want the cite command to be citep or citet, respectively.
• biblatex. Generates biblatex citation commands. Extra URL parameters allowed:
  • command: the citation command to use (if unspecified, defaults to autocite)
• mmd: MultiMarkdown
• pandoc. Accepts additional URL parameter brackets; any non-empty value surrounds the citation with brackets
• asciidoctor-bibtex
• typst Generates typst citation commands
• jupyter
• scannable-cite for the ODF scanner
• formatted-citation: output formatted citation as per the current Zotero quick-export setting, if it is set to a citation style, and not an export format
• formatted-bibliography: output formatted bibliography as per the current Zotero quick-export setting, if it is set to a citation style, and not an export format
• translate invokes a Zotero export translator. Extra URL parameters allowed:
  • translator: stripped name of one of the BBT translators (lowercased, remove ‘better’, and only the letters, e.g. biblatex or csljson), or a translator ID. Defaults to biblatex.
  • exportNotes: set to true to export notes
  • useJournalAbbreviation: set to true to use journal abbreviations
• json: the full pick information Zotero provides.
• eta: formats the pick using Eta, with the picks exposed as it.items. To see what the items look like, use the json formatter. URL parameter required:
  • template: the Eta template to render

The eta formatter is great for experimentation, but if you need a format for a common target application, feel free to request a change to have that added to this list.

The picker passes the following data along with your picked items if you filled them out:

However not all output formats support these. Pandoc and scannable cite are the richest ones, supporting all 4. MultiMarkdown supports none. The formatted- formats will ignore these. LaTeX supports all 4, in a way:

• in the latex (natbib) format: if you choose suppress author for none or all of your items in a pick, you will get the citation as you would normally enter it, such as \cite{author1,author2}, or \citeyear{author1,author2}. If you use locator, prefix, suffix in any one of them, or you use suppress author for some but not for others, the picker will write them out all separate, like \cite[p. 1]{author1}\citeyear{author2}, as natbib doesn’t seem to have a good mechanism for combined citations that mix different prefixes/suffixes/locators.
• in the biblatex format: suppress author is ignored unless the command is one of \cite, \autocite or \parencite and there is one items only, in which case the starred variant of the command is returned, which hides the author; for multiple items with locators, prefixes or suffixes, the s-affixed variant of the command is generated

Some of the formatters use abbreviated labels for the results if you include a locator. The defaults are:

In your call to the CAYW URL, you can override the abbreviations by adding them to the query, e.g. http://127.0.0.1:23119/better-bibtex/cayw?format=mmd&page=&Section=sec., page-picks will have no label, and Section-picks will get sec. rather than Sec..

The clipboard option can be used as a workaround for editors that haven’t gotten around to integrating this yet. If you use this option you will probably want to bind to a hotkey, either system-wide (which is going to be platform-dependent, I know AutoHotKey works for windows, for OSX Karabiner ought to do the job, and for Linux xbindkeys could do the job.

For example, if you call up http://127.0.0.1:23119/better-bibtex/cayw?format=mmd&clipboard=yes, the Zotero citation picker will pop up. If you then select two items that happen to have cite keys adams2001 and brigge2002, then

• the response body will be [#adams2001][][#brigge2002][], and
• [#adams2001][][#brigge2002][] will be left on the clipboard
