#Meta-Xref backend

Find here the source for xref-union.el, an meta-Xref backed for combining the results of multiple other backends.

#Installation

Xref-union.el is avaliable from GNU ELPA. It can be installed by invoking

M-x package-install RET xref-union RET

#Usage

The easiest way to use the package is to enable the xref-union-mode minor mode, manually or by adding a hook to whatever mode you expect using the package with

(add-hook 'foo-bar-mode-hook 'xref-union-mode)

This will merge all the other backends into one.

You can also manually choose what backends to combine, by enumerating them in an object like:

'(union some-randomxref-backend etags--xref-backend)

and adding that to xref-backend-functions.
