company-reftex

This package provides two backends for Company for completing label references and citations in LaTeX. It is based on RefTeX, which is included with Emacs.

To use, add the backends to company-backends in the buffers where you want them activated. Make sure that reftex-mode is enabled also.

These backends should work well together with other LaTeX company backends, for example:

• company-auctex (note that company-reftex should be considerably more powerful than company-auctex's backends for labels and citations, however company-auctex has other backends that may be of interest).
• company-math

company-reftex-labels

This backend completes labels, and activates in \ref{}, \eqref{} and \autoref{}. By default, the completions are annotated with their contents, to help find the right one. This can be disabled by customizing company-reftex-annotate-labels. The maximal annotation length can be modified with company-reftex-max-annotation-length.

company-reftex-citations

This backend completes citations, and activates in cite{}. RefTeX, and by extension this package, will find citations in a \begin{thebibliography} environment, as well as citations in external BibTeX files. By default, the completions are annotated with the title of the cited publication, to help you find the right one. This can be disabled by customizing company-reftex-annotate-citations. The maximal annotation length can be modified with company-reftex-max-annotation-length.

Note that RefTeX searches for bibliography entries in names, titles, journals and all sorts of places. This backend leverages this feature. In effect, the matching becomes very, very fuzzy indeed.

Tips

When working with multi-file documents, ensure that the variable TeX-master is appropriately set in all files, so that RefTeX can find citations across documents.
