|
| +# Explanation for this rule:
|
| +#
|
| +# It needs to back over
|
| +# The $Sep at which we probably begin
|
| +# All of the non $Sep chars leading to the preceding $Sep
|
| +# The preceding $Sep, which will be the second one that the rule matches.
|
| +# Any immediately preceding STerm or ATerm sequences. We need to see these
|
| +# to get the correct rule status when moving forwards again.
|
| +#
|
| +# [{bof}] inhibit rule chaining. Without this, rule would loop on itself and match
|
| +# the entire string.
|
| +#
|
| +# (.? | $LF $CR) Match one $Sep instance. Use .? rather than $Sep because position might be
|
| +# at the beginning of the string at this point, and we don't want to fail.
|
| +# Can only use {eof} once, and it is used later.
