@ -99,14 +99,20 @@ Care should be taken when parsing and interpreting HTML, whether full documents
or fragments, within the framework of the HTML specification, especially with
regard to untrusted inputs.
This package provides both a tokenizer and a parser. Only the parser constructs
a DOM according to the HTML specification, resolving malformed and misplaced
tags where appropriate. The tokenizer simply tokenizes the HTML presented to it,
and as such does not resolve issues that may exist in the processed HTML,
producing a literal interpretation of the input.
This package provides both a tokenizer and a parser, which implement the
tokenization, and tokenization and tree construction stages of the WHATWG HTML
parsing specification respectively. While the tokenizer parses and normalizes
individual HTML tokens, only the parser constructs the DOM tree from the
tokenized HTML, as described in the tree construction stage of the
specification, dynamically modifying or extending the docuemnt's DOM tree.
If your use case requires semantically well-formed HTML, as defined by the
WHATWG specifiction, the parser should be used rather than the tokenizer.
If your use case requires semantically well-formed HTML documents, as defined by
the WHATWG specification, the parser should be used rather than the tokenizer.
In security contexts, if trust decisions are being made using the tokenized or
parsed content, the input must be re-serialized (for instance by using Render or
Token.String) in order for those trust decisions to hold, as the process of
tokenization or parsing may alter the content.

// OT object->type Object.Type
// TT type->type Type.{Elem,Key,Params,Results,Underlying} [EKPRU]
// TO type->object Type.{At,Field,Method,Obj} [AFMO]
//
// All valid paths start with a package and end at an object
// and thus may be defined by the regular language:
//
// objectpath = PO (OT TT* TO)*
//
// The concrete encoding follows directly:
// - The only PO operator is Package.Scope.Lookup, which requires an identifier.
// - The only OT operator is Object.Type,
// which we encode as '.' because dot cannot appear in an identifier.
// - The TT operators are encoded as [EKPRUTC];
// one of these (TypeParam) requires an integer operand,
// which is encoded as a string of decimal digits.
// - The TO operators are encoded as [AFMO];
// three of these (At,Field,Method) require an integer operand,
// which is encoded as a string of decimal digits.
// These indices are stable across different representations
// of the same package, even source and export data.
// The indices used are implementation specific and may not correspond to
// the argument to the go/types function.
//
// In the example below,
//
// package p
//
// type T interface {
// f() (a string, b struct{ X int })
// }
//
// field X has the path "T.UM0.RA1.F0",
// representing the following sequence of operations:
//
// p.Lookup("T") T
// .Type().Underlying().Method(0). f
// .Type().Results().At(1) b
// .Type().Field(0) X
//
// The encoding is not maximally compact---every R or P is
// followed by an A, for example---but this simplifies the
// encoder and decoder.

//
// Methods on generic types require special consideration, however. Consider

//
// L1: type S[T any] struct{}
// L2: func (recv S[A]) Foo() { recv.Bar() }
// L3: func (recv S[B]) Bar() { }
// L4: type Alias = S[int]
// L5: func _[T any]() { var s S[int]; s.Foo() }
//
// The receivers of methods on generic types are instantiations. L2 and L3
// instantiate S with the type-parameters A and B, which are scoped to the
// respective methods. L4 and L5 each instantiate S with int. Each of these
// instantiations has its own method set, full of methods (and thus objects)
// with receivers whose types are the respective instantiations. In other
// words, we have
//
// S[A].Foo, S[A].Bar
// S[B].Foo, S[B].Bar
// S[int].Foo, S[int].Bar
//
// We may thus be trying to produce object paths for any of these objects.
//
// S[A].Foo and S[B].Bar are the origin methods, and their paths are S.Foo
// and S.Bar, which are the paths that this function naturally produces.
//
// S[A].Bar, S[B].Foo, and both methods on S[int] are instantiations that
// don't correspond to the origin methods. For S[int], this is significant.
// The most precise object path for S[int].Foo, for example, is Alias.Foo,
// not S.Foo. Our function, however, would produce S.Foo, which would
// resolve to a different object.
//
// For S[A].Bar and S[B].Foo it could be argued that S.Bar and S.Foo are
// still the correct paths, since only the origin methods have meaningful
// paths. But this is likely only true for trivial cases and has edge cases.
// Since this function is only an optimization, we err on the side of giving
// up, deferring to the slower but definitely correct algorithm. Most users
// of objectpath will only be giving us origin methods, anyway, as referring
