Documentation

Alist of extensions to try when switching to a file's counterpart.

Keys and values are extensions without the leading dot; the key nil stands for a file with no extension at all. Each value lists the extensions projectile-find-other-file offers for a file with that key's extension, in the order they are tried.

This variable was added, or its default value changed, in projectile version 0.12.0.
