/*
|
|
Created to solve the key deficiently with MultiRegex - there is no way to
|
|
test for multiple matches at a single location. Why would we need to do
|
|
that? In the future a more dynamic engine will allow certain matches to be
|
|
ignored. An example: if we matched say the 3rd regex in a large group but
|
|
decided to ignore it - we'd need to started testing again at the 4th
|
|
regex... but MultiRegex itself gives us no real way to do that.
|
|
|
|
So what this class creates MultiRegexs on the fly for whatever search
|
|
position they are needed.
|
|
|
|
NOTE: These additional MultiRegex objects are created dynamically. For most
|
|
grammars most of the time we will never actually need anything more than the
|
|
first MultiRegex - so this shouldn't have too much overhead.
|
|
|
|
Say this is our search group, and we match regex3, but wish to ignore it.
|
|
|
|
regex1 | regex2 | regex3 | regex4 | regex5 ' ie, startAt = 0
|
|
|
|
What we need is a new MultiRegex that only includes the remaining
|
|
possibilities:
|
|
|
|
regex4 | regex5 ' ie, startAt = 3
|
|
|
|
This class wraps all that complexity up in a simple API... `startAt` decides
|
|
where in the array of expressions to start doing the matching. It
|
|
auto-increments, so if a match is found at position 2, then startAt will be
|
|
set to 3. If the end is reached startAt will return to 0.
|
|
|
|
MOST of the time the parser will be setting startAt manually to 0.

|
|
// far looking only for "number", ignoring potential string matches (or

|
// future "booger" matches that might be valid.)

|
// a prior rule that was ignored".
|
|
//
|
|
// 1. Match "booger" first, ignore. Also proves that [string] does non match.
|
|
// 2. Resume matching for [number]
|

// 3. Match at index + 1 for [string, "booger", number]
