-// This method computes the SLL prediction termination condition for both of -// the following cases.

-// -// -// -//

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”, {})}

-// -//

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.

-// -//

CASES

-// -// -// -//

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...

After this point, the runtime +source code to be imported was held in the `runtime/Go/antlr/v4` directory, and the go.mod file was updated to reflect the version of +ANTLR4 that it is compatible with (I.E. uses the /v4 path). + +However, this was found to be problematic, as it meant that with the runtime embedded so far underneath the root +of the repo, the `go get` and related commands could not properly resolve the location of the go runtime source code. +This meant that the reference to the runtime in your `go.mod` file would refer to the correct source code, but would not +list the release tag such as @4.12.0 - this was confusing, to say the least. + +As of 4.12.1, the runtime is now available as a go module in its own repo, and can be imported as `github.com/antlr4-go/antlr` +(the go get command should also be used with this path). See the main documentation for the ANTLR4 project for more information, +which is available at [ANTLR docs]. The documentation for using the Go runtime is available at [Go runtime docs]. + +This means that if you are using the source code without modules, you should also use the source code in the [new repo]. +Though we highly recommend that you use go modules, as they are now idiomatic for Go. + +I am aware that this change will prove Hyrum's Law, but am prepared to live with it for the common good. + +Go runtime author: [Jim Idle] jimi@idle.ws + +# Code Generation + +ANTLR supports the generation of code in a number of [target languages], and the generated code is supported by a +runtime library, written specifically to support the generated code in the target language. This library is the +runtime for the Go target. + +To generate code for the go target, it is generally recommended to place the source grammar files in a package of +their own, and use the `.sh` script method of generating code, using the go generate directive. In that same directory +it is usual, though not required, to place the antlr tool that should be used to generate the code. That does mean +that the antlr tool JAR file will be checked in to your source code control though, so you are, of course, free to use any other +way of specifying the version of the ANTLR tool to use, such as aliasing in `.zshrc` or equivalent, or a profile in +your IDE, or configuration in your CI system. Checking in the jar does mean that it is easy to reproduce the build as +it was at any point in its history. + +Here is a general/recommended template for an ANTLR based recognizer in Go: + + . + ├── parser + │ ├── mygrammar.g4 + │ ├── antlr-4.12.1-complete.jar + │ ├── generate.go + │ └── generate.sh + ├── parsing - generated code goes here + │ └── error_listeners.go + ├── go.mod + ├── go.sum + ├── main.go + └── main_test.go + +Make sure that the package statement in your grammar file(s) reflects the go package the generated code will exist in. + +The generate.go file then looks like this: + + package parser + + //go:generate ./generate.sh + +And the generate.sh file will look similar to this: + + #!/bin/sh + + alias antlr4='java -Xmx500M -cp "./antlr4-4.12.1-complete.jar:$CLASSPATH" org.antlr.v4.Tool' + antlr4 -Dlanguage=Go -no-visitor -package parsing *.g4 + +depending on whether you want visitors or listeners or any other ANTLR options. Not that another option here +is to generate the code into a + +From the command line at the root of your source package (location of go.mo)d) you can then simply issue the command: + + go generate ./... + +Which will generate the code for the parser, and place it in the parsing package. You can then use the generated code +by importing the parsing package. + +There are no hard and fast rules on this. It is just a recommendation.

If +// the union of these alternative subsets is a singleton, then no amount of +// further 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: +// +// (s, i, x) and (s, j, x') +// +// conflict when i != j but x = x'. Because we merge all +// (s, i, _) configurations together, that means that there are at +// most n configurations associated with state s for +// n possible alternatives in the decision. The merged stacks +// complicate the comparison of configuration contexts x and 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 x or x'. +// If the x associated with lowest alternative i +// is the superset, then i is the only possible prediction since the +// others resolve to min(i) as well. However, if x is +// associated with j > i then at least one stack configuration for +// j is not in conflict with alternative i. The algorithm +// should keep going, looking for more lookahead due to the uncertainty. +// +// For simplicity, I'm doing an equality check between x and +// x', which lets the algorithm continue to consume lookahead longer +// than necessary.
