The
current earleme
is the earleme that Libmarpa is currently working on.
More specifically, it is the one at which new tokens will start.
Since tokens are never zero length, a new token will always end after the
current earleme.
marpa_r_start_input()
initializes the current earleme to 0,
and every call to
marpa_r_earleme_complete()
advances the
current earleme by 1.
The marpa_r_start input()
and
marpa_r_earleme_complete()
methods
are only ones that change the current earleme.
See marpa_r_start_input() and
marpa_r_earleme_complete().
