expkv – An expandable key=val implementation

expkv is a minimalistic but fast and expandable <key>=<val> implementation.

It provides two parsing macros:

• \ekvset{<set>}{<key=val list>} which is comparable to keyval’s \setkeys.
• \ekvparse<cs1><cs2>{<key=val list>} which can be used inside \expanded and expands to <cs1>{key} and <cs2>{key}{val} for the entries in the <key=val list>.

expkv has predictable brace-stripping behaviour and handles commas and equal signs with category codes 12 and 13 correctly.

A key-defining interface that is not as rudimentary as the macros provided in this package is contained in expkv-def.
