+// +// 
+// a : Sync ( stuff Sync )*
+// Sync : {consume to what can follow Sync}
+//
+// +// At the start of a sub rule upon error, {@link //Sync} performs single +// token deletion, if possible. If it can't do that, it bails on the current +// rule and uses the default error recovery, which consumes until the +// reSynchronization set of the current rule. +// +//

If the sub rule is optional ({@code (...)?}, {@code (...)*}, or block +// with an empty alternative), then the expected set includes what follows +// the subrule.

+// +//

During loop iteration, it consumes until it sees a token that can start a +// sub rule or what follows loop. Yes, that is pretty aggressive. We opt to +// stay in the loop as long as possible.

+// +//

ORIGINS

+// +//

Previous versions of ANTLR did a poor job of their recovery within loops. +// A single mismatch token or missing token would force the parser to bail +// out of the entire rules surrounding the loop. So, for rule

+// +// 
+// classfunc : 'class' ID '{' member* '}'
+//

The default implementation attempts to recover from the mismatched input +// by using single token insertion and deletion as described below. If the +// recovery attempt fails, d method panics an +// {@link InputMisMatchException}.

+// +//

EXTRA TOKEN (single token deletion)

+// +//

{@code LA(1)} is not what we are looking for. If {@code LA(2)} has the +// right token, however, then assume {@code LA(1)} is some extra spurious +// token and delete it. Then consume and return the next token (which was +// the {@code LA(2)} token) as the successful result of the Match operation.

+// +//

This recovery strategy is implemented by {@link +// //singleTokenDeletion}.

+// +//

MISSING TOKEN (single token insertion)

+// +//

If current token (at {@code LA(1)}) is consistent with what could come +// after the expected {@code LA(1)} token, then assume the token is missing +// and use the parser's {@link TokenFactory} to create it on the fly. The +// "insertion" is performed by returning the created token as the successful +// result of the Match operation.

+// +//

This recovery strategy is implemented by {@link +// //singleTokenInsertion}.

+// +//

EXAMPLE

+// +//

For example, Input {@code i=(3} is clearly missing the {@code ')'}. When +// the parser returns from the nested call to {@code expr}, it will have +// call chain:

+// +// 
+// stat &rarr expr &rarr atom
+//
+// +// and it will be trying to Match the {@code ')'} at d point in the +// derivation: +// +// 
+// => ID '=' '(' INT ')' ('+' atom)* ''
+// ^
+//
+// +// The attempt to Match {@code ')'} will fail when it sees {@code ''} and +// call {@link //recoverInline}. To recover, it sees that {@code LA(1)==''} +// is in the set of tokens that can follow the {@code ')'} token reference +// in rule {@code atom}. It can assume that you forgot the {@code ')'}. +// +func (d *DefaultErrorStrategy) RecoverInline(recognizer Parser) Token { + // SINGLE TOKEN DELETION + MatchedSymbol := d.SingleTokenDeletion(recognizer) + if MatchedSymbol != nil { + // we have deleted the extra token. + // now, move past ttype token as if all were ok + recognizer.Consume() + return MatchedSymbol + } + // SINGLE TOKEN INSERTION + if d.SingleTokenInsertion(recognizer) { + return d.GetMissingSymbol(recognizer) + } + // even that didn't work must panic the exception + panic(NewInputMisMatchException(recognizer)) +} + +// +// This method implements the single-token insertion inline error recovery +// strategy. It is called by {@link //recoverInline} if the single-token +// deletion strategy fails to recover from the mismatched input. If this +// method returns {@code true}, {@code recognizer} will be in error recovery +// mode. +// +//

This method determines whether or not single-token insertion is viable by +// checking if the {@code LA(1)} input symbol could be successfully Matched +// if it were instead the {@code LA(2)} symbol. If d method returns +// {@code true}, the caller is responsible for creating and inserting a +// token with the correct type to produce d behavior.

If that token is missing, but +// the next token in the stream is what we want we assume that +// d token is missing and we keep going.

Note that FOLLOW(c)='^' and if +// we reSync'd to that token, we'd consume until EOF. We need to +// Sync to context-sensitive FOLLOWs for a, b, and c: {']','^'}. +// In this case, for input "[]", LA(1) is ']' and in the set, so we would +// not consume anything. After printing an error, rule c would +// return normally.

To support output-preserving grammar transformations (including but not +// limited to left-recursion removal, automated left-factoring, and +// optimized code generation), calls to listener methods during the parse +// may differ substantially from calls made by +// {@link ParseTreeWalker//DEFAULT} used after the parse is complete. In +// particular, rule entry and exit events may occur in a different order +// during the parse than after the parser. In addition, calls to certain +// rule entry methods may be omitted.

+// +//

With the following specific exceptions, calls to listener events are +// deterministic, i.e. for identical input the calls to listener +// methods will be the same.

  • Alterations to the grammar used to generate code may change the +// behavior of the listener calls.
    • +//
  • Alterations to the command line options passed to ANTLR 4 when +// generating the parser may change the behavior of the listener calls.

    • +//
  • Pure SLL without LL fallback
    • +//
+// +//

COMBINED SLL+LL PARSING

+// +//

When LL-fallback is enabled upon SLL conflict, correct predictions are +// ensured regardless of how the termination condition is computed by this +// method. Due to the substantially higher cost of LL prediction, the +// prediction should only fall back to LL when the additional lookahead +// cannot lead to a unique SLL prediction.

+// +//

Assuming combined SLL+LL parsing, an SLL configuration set with only +// conflicting subsets should fall back to full LL, even if the +// configuration sets don't resolve to the same alternative (e.g. +// {@code {1,2}} and {@code {3,4}}. If there is at least one non-conflicting +// configuration, SLL could continue with the hopes that more lookahead will +// resolve via one of those non-conflicting configurations.

+// +//

Here's the prediction termination rule them: SLL (for SLL+LL parsing) +// stops when it sees only conflicting configuration subsets. In contrast, +// full LL keeps going when there is uncertainty.

+// +//

HEURISTIC

+// +//

As a heuristic, we stop prediction when we see any conflicting subset +// unless we see a state that only has one alternative associated with it. +// The single-alt-state thing lets prediction continue upon rules like +// (otherwise, it would admit defeat too soon):

+// +//

{@code [12|1|[], 6|2|[], 12|2|[]]. s : (ID | ID ID?) '' }

+// +//

When the ATN simulation reaches the state before {@code ''}, it has a +// DFA state that looks like: {@code [12|1|[], 6|2|[], 12|2|[]]}. Naturally +// {@code 12|1|[]} and {@code 12|2|[]} conflict, but we cannot stop +// processing this node because alternative to has another way to continue, +// via {@code [6|2|[]]}.

+// +//

It also let's us continue for this rule:

+// +//

{@code [1|1|[], 1|2|[], 8|3|[]] a : A | A | A B }

+// +//

After Matching input A, we reach the stop state for rule A, state 1. +// State 8 is the state right before B. Clearly alternatives 1 and 2 +// conflict and no amount of further lookahead will separate the two. +// However, alternative 3 will be able to continue and so we do not stop +// working on this state. In the previous example, we're concerned with +// states associated with the conflicting alternatives. Here alt 3 is not +// associated with the conflicting configs, but since we can continue +// looking for input reasonably, don't declare the state done.

+// +//

PURE SLL PARSING

+// +//

To handle pure SLL parsing, all we have to do is make sure that we +// combine stack contexts for configurations that differ only by semantic +// predicate. From there, we can do the usual SLL termination heuristic.

+// +//

PREDICATES IN SLL+LL PARSING

+// +//

SLL decisions don't evaluate predicates until after they reach DFA stop +// states because they need to create the DFA cache that works in all +// semantic situations. In contrast, full LL evaluates predicates collected +// during start state computation so it can ignore predicates thereafter. +// This means that SLL termination detection can totally ignore semantic +// predicates.

+// +//

Implementation-wise, {@link ATNConfigSet} combines stack contexts but not +// semantic predicate contexts so we might see two configurations like the +// following.

+// +//

{@code (s, 1, x, {}), (s, 1, x', {p})}

+// +//

Before testing these configurations against others, we have to merge +// {@code x} and {@code x'} (without modifying the existing configurations). +// For example, we test {@code (x+x')==x''} when looking for conflicts in +// the following configurations.

+// +//

{@code (s, 1, x, {}), (s, 1, x', {p}), (s, 2, x'', {})}

+// +//

If the configuration set has predicates (as indicated by +// {@link ATNConfigSet//hasSemanticContext}), this algorithm makes a copy of +// the configurations to strip out all of the predicates so that a standard +// {@link ATNConfigSet} will merge everything ignoring predicates.

+// +func PredictionModehasSLLConflictTerminatingPrediction(mode int, configs ATNConfigSet) bool { + // Configs in rule stop states indicate reaching the end of the decision + // rule (local context) or end of start rule (full context). If all + // configs meet this condition, then none of the configurations is able + // to Match additional input so we terminate prediction. + // + if PredictionModeallConfigsInRuleStopStates(configs) { + return true + } + // pure SLL mode parsing + if mode == PredictionModeSLL { + // Don't bother with combining configs from different semantic + // contexts if we can fail over to full LL costs more time + // since we'll often fail over anyway. + if configs.HasSemanticContext() { + // dup configs, tossing out semantic predicates + dup := NewBaseATNConfigSet(false) + for _, c := range configs.GetItems() { + + // NewBaseATNConfig({semanticContext:}, c) + c = NewBaseATNConfig2(c, SemanticContextNone) + dup.Add(c, nil) + } + configs = dup + } + // now we have combined contexts for configs with dissimilar preds + } + // pure SLL or combined SLL+LL mode parsing + altsets := PredictionModegetConflictingAltSubsets(configs) + return PredictionModehasConflictingAltSet(altsets) && !PredictionModehasStateAssociatedWithOneAlt(configs) +} + +// Checks if any configuration in {@code configs} is in a +// {@link RuleStopState}.

Can we stop looking ahead during ATN simulation or is there some +// uncertainty as to which alternative we will ultimately pick, after +// consuming more input? Even if there are partial conflicts, we might know +// that everything is going to resolve to the same minimum alternative. That +// means we can stop since no more lookahead will change that fact. On the +// other hand, there might be multiple conflicts that resolve to different +// minimums. That means we need more look ahead to decide which of those +// alternatives we should predict.

+// +//

The basic idea is to split the set of configurations {@code C}, into +// conflicting subsets {@code (s, _, ctx, _)} and singleton subsets with +// non-conflicting configurations. Two configurations conflict if they have +// identical {@link ATNConfig//state} and {@link ATNConfig//context} values +// but different {@link ATNConfig//alt} value, e.g. {@code (s, i, ctx, _)} +// and {@code (s, j, ctx, _)} for {@code i!=j}.

+// +//

Reduce these configuration subsets to the set of possible alternatives. +// You can compute the alternative subsets in one pass as follows:

+// +//

{@code A_s,ctx = {i | (s, i, ctx, _)}} for each configuration in +// {@code C} holding {@code s} and {@code ctx} fixed.

+// +//

Or in pseudo-code, for each configuration {@code c} in {@code C}:

+// +// 
+// map[c] U= c.{@link ATNConfig//alt alt} // map hash/equals uses s and x, not
+// alt and not pred
+//
+// +//

The values in {@code map} are the set of {@code A_s,ctx} sets.

+// +//

If {@code |A_s,ctx|=1} then there is no conflict associated with +// {@code s} and {@code ctx}.

+// +//

Reduce the subsets to singletons by choosing a minimum of each subset. If +// the union of these alternative subsets is a singleton, then no amount of +// more lookahead will help us. We will always pick that alternative. If, +// however, there is more than one alternative, then we are uncertain which +// alternative to predict and must continue looking for resolution. We may +// or may not discover an ambiguity in the future, even if there are no +// conflicting subsets this round.

+// +//

The biggest sin is to terminate early because it means we've made a +// decision but were uncertain as to the eventual outcome. We haven't used +// enough lookahead. On the other hand, announcing a conflict too late is no +// big deal you will still have the conflict. It's just inefficient. It +// might even look until the end of file.

+// +//

No special consideration for semantic predicates is required because +// predicates are evaluated on-the-fly for full LL prediction, ensuring that +// no configuration contains a semantic context during the termination +// check.

+// +//

CONFLICTING CONFIGS

+// +//

Two configurations {@code (s, i, x)} and {@code (s, j, x')}, conflict +// when {@code i!=j} but {@code x=x'}. Because we merge all +// {@code (s, i, _)} configurations together, that means that there are at +// most {@code n} configurations associated with state {@code s} for +// {@code n} possible alternatives in the decision. The merged stacks +// complicate the comparison of configuration contexts {@code x} and +// {@code x'}. Sam checks to see if one is a subset of the other by calling +// merge and checking to see if the merged result is either {@code x} or +// {@code x'}. If the {@code x} associated with lowest alternative {@code i} +// is the superset, then {@code i} is the only possible prediction since the +// others resolve to {@code min(i)} as well. However, if {@code x} is +// associated with {@code j>i} then at least one stack configuration for +// {@code j} is not in conflict with alternative {@code i}. The algorithm +// should keep going, looking for more lookahead due to the uncertainty.

+// +//

For simplicity, I'm doing a equality check between {@code x} and +// {@code x'} that lets the algorithm continue to consume lookahead longer +// than necessary. The reason I like the equality is of course the +// simplicity but also because that is the test you need to detect the +// alternatives that are actually in conflict.

+// +//

CONTINUE/STOP RULE

+// +//

Continue if union of resolved alternative sets from non-conflicting and +// conflicting alternative subsets has more than one alternative. We are +// uncertain about which alternative to predict.

+// +//

The complete set of alternatives, {@code [i for (_,i,_)]}, tells us which +// alternatives are still in the running for the amount of input we've +// consumed at this point. The conflicting sets let us to strip away +// configurations that won't lead to more states because we resolve +// conflicts to the configuration with a minimum alternate for the +// conflicting set.

+// +//

EXACT AMBIGUITY DETECTION

+// +//

If all states Report the same conflicting set of alternatives, then we +// know we have the exact ambiguity set.

|A_i|>1 and +// A_i = A_j for all i, j.

+// +//

In other words, we continue examining lookahead until all {@code A_i} +// have more than one alternative and all {@code A_i} are the same. If +// {@code A={{1,2}, {1,3}}}, then regular LL prediction would terminate +// because the resolved set is {@code {1}}. To determine what the real +// ambiguity is, we have to know whether the ambiguity is between one and +// two or one and three so we keep going. We can only stop prediction when +// we need exact ambiguity detection when the sets look like +// {@code A={{1,2}}} or {@code {{1,2},{1,2}}}, etc...

+// You can insert stuff, replace, and delete chunks. Note that the operations +// are done lazily--only if you convert the buffer to a {@link String} with +// {@link TokenStream#getText()}. This is very efficient because you are not +// moving data around all the time. As the buffer of tokens is converted to +// strings, the {@link #getText()} method(s) scan the input token stream and +// check to see if there is an operation at the current index. If so, the +// operation is done and then normal {@link String} rendering continues on the +// buffer. This is like having multiple Turing machine instruction streams +// (programs) operating on a single input tape. :)

+//

+ +// This rewriter makes no modifications to the token stream. It does not ask the +// stream to fill itself up nor does it advance the input cursor. The token +// stream {@link TokenStream#index()} will return the same value before and +// after any {@link #getText()} call.

+ +//

+// The rewriter only works on tokens that you have in the buffer and ignores the +// current input cursor. If you are buffering tokens on-demand, calling +// {@link #getText()} halfway through the input will only do rewrites for those +// tokens in the first half of the file.

+ +//

+// Since the operations are done lazily at {@link #getText}-time, operations do +// not screw up the token index values. That is, an insert operation at token +// index {@code i} does not change the index values for tokens +// {@code i}+1..n-1.

+ +//

+// Because operations never actually alter the buffer, you may always get the +// original token stream back without undoing anything. Since the instructions +// are queued up, you can easily simulate transactions and roll back any changes +// if there is an error just by removing instructions. For example,

+ +// 
+// CharStream input = new ANTLRFileStream("input");
+// TLexer lex = new TLexer(input);
+// CommonTokenStream tokens = new CommonTokenStream(lex);
+// T parser = new T(tokens);
+// TokenStreamRewriter rewriter = new TokenStreamRewriter(tokens);
+// parser.startRule();
+//
+ +//

+// Then in the rules, you can execute (assuming rewriter is visible):

+ +// 
+// Token t,u;
+// ...
+// rewriter.insertAfter(t, "text to put after t");}
+// rewriter.insertAfter(u, "text after u");}
+// System.out.println(rewriter.getText());
+//
+ +//

+// You can also have multiple "instruction streams" and get multiple rewrites +// from a single pass over the input. Just name the instruction streams and use +// that name again when printing the buffer. This could be useful for generating +// a C file and also its header file--all from the same buffer:

+ +// 
+// rewriter.insertAfter("pass1", t, "text to put after t");}
+// rewriter.insertAfter("pass2", u, "text after u");}
+// System.out.println(rewriter.getText("pass1"));
+// System.out.println(rewriter.getText("pass2"));
+//
