Name
$*
Synopsis
The $*
operator is a wildcard operator. It is used
to match zero or more tokens in the workspace. One handy use for it
is to honor a pair of angle braces, regardless of whether that pair
has something between them. The following LHS, for example, will
match <>
, or
<wash>
, or even
<some.big.long.domain>
:
R < $* > ...
But because $*
can match an unexpected number of
tokens, it is wise to understand minimum matching before using it.
See Section 18.6.1 for a discussion of minimum matching
and the backup and retry process.
Note that the $*
operator can be used only on the
LHS of rules, and can be referenced by an RHS
$
digit
operator.
