I am a parser created to parse the insides of a character set ([...]) construct. I create and answer a collection of "elements", each being an instance of one of: RxsCharacter, RxsRange, or RxsPredicate.
Instance Variables:
source <Stream> open on whatever is inside the square brackets we have to parse.
lookahead <Character> The current lookahead character
elements <Collection of: <RxsCharacter|RxsRange|RxsPredicate>> Parsing result!

-- Regular Expression Matcher v 1.1 (C) 1996, 1999 Vassili Bykov
--
A match start optimizer, handy for searching a string. Takes a regex syntax tree and sets itself up so that prefix characters or matcher states that cannot start a match are later recognized with #canStartMatch:in: method.
Used by RxMatcher, but can be used by other matchers (if implemented) as well.!

This is a recursive regex matcher. Not strikingly efficient, but simple. Also, keeps track of matched subexpressions. The life cycle goes as follows:
1. Initialization. Accepts a syntax tree (presumably produced by RxParser) and compiles it into a matcher built of other classes in this category.
2. Matching. Accepts a stream or a string and returns a boolean indicating whether the whole stream or its prefix -- depending on the message sent -- matches the regex.
3. Subexpression query. After a successful match, and before any other match, the matcher may be queried about the range of specific stream (string) positions that matched to certain parenthesized subexpressions of the original expression.
Any number of queries may follow a successful match, and any number or matches may follow a successful initialization.
Note that `matcher' is actually a sort of a misnomer. The actual matcher is a web of Rxm* instances built by RxMatcher during initialization. RxMatcher is just the interface facade of this network. It is also a builder of it, and also provides a stream-like protocol to easily access the stream being matched.
Instance variables:
matcher <RxmLink> The entry point into the actual matcher.
stream <Stream> The stream currently being matched against.
markerPositions <Array of: Integer> Positions of markers' matches.
markerCount <Integer> Number of markers.
lastResult <Boolean> Whether the latest match attempt succeeded or not.
lastChar <Character | nil> character last seen in the matcher stream!

The regular expression parser. Translates a regular expression read from a stream into a parse tree. ('accessing' protocol). The tree can later be passed to a matcher initialization method. All other classes in this category implement the tree. Refer to their comments for any details.
Instance variables:
input <Stream> A stream with the regular expression being parsed.
lookahead <Character>!

-- Regular Expression Matcher v 1.1 (C) 1996, 1999 Vassili Bykov

A matcher is built of a number of links interconnected into some intricate structure. Regardless of fancy stuff, any link (except for the terminator) has the next one. Any link can match against a stream of characters, recursively propagating the match to the next link. Any link supports a number of matcher-building messages. This superclass does all of the above.
The class is not necessarily abstract. It may double as an empty string matcher: it recursively propagates the match to the next link, thus always matching nothing successfully.
Principal method:
matchAgainst: aMatcher
Any subclass will reimplement this to test the state of the matcher, most
probably reading one or more characters from the matcher's stream, and
either decide it has matched and answer true, leaving matcher stream
positioned at the end of match, or answer false and restore the matcher
stream position to whatever it was before the matching attempt.
Instance variables:
next <RxmLink | RxmTerminator> The next link in the structure.!

This is a branch of a matching process. Either `next' chain should match, or `alternative', if not nil, should match. Since this is also used to build loopbacks to match repetitions, `loopback' variable indicates whether the instance is a loopback: it affects the matcher-building operations (which of the paths through the branch is to consider as the primary when we have to find the "tail" of a matcher construct).
Instance variables
alternative <RxmLink> to match if `next' fails to match.
loopback <Boolean>!

A marker is used to remember positions of match of certain points of a regular expression. The marker receives an identifying key from the Matcher and uses that key to report positions of successful matches to the Matcher.
Instance variables:
index <Object> Something that makes sense for the Matcher. Received from the latter during initalization and later passed to it to identify the receiver.!
