// addStatementCandidates adds full statement completion candidates

// addAssignAppend offers a completion candidate of the form:
//
//	someSlice = append(someSlice, )
//
// It will offer the "append" completion in either of two situations:
//
//  1. Position is in RHS of assign, prefix matches "append", and
//     corresponding LHS object is a slice. For example,
//     "foo = ap<>" completes to "foo = append(foo, )".
//
//  2. Prefix is an ident or selector in an *ast.ExprStmt (i.e.
//     beginning of statement), and our best matching candidate is a
//     slice. For example: "foo.ba" completes to "foo.bar = append(foo.bar, )".
func (c *completer) addAssignAppend() { … }

// topCandidate returns the strictly highest scoring candidate
// collected so far. If the top two candidates have the same score,
// nil is returned.
func (c *completer) topCandidate() *CompletionItem { … }

// addErrCheck offers a completion candidate of the form:
//
//	if err != nil {
//	  return nil, err
//	}
//
// In the case of test functions, it offers a completion candidate of the form:
//
//	if err != nil {
//	  t.Fatal(err)
//	}
//
// The position must be in a function that returns an error, and the
// statement preceding the position must be an assignment where the
// final LHS object is an error. addErrCheck will synthesize
// zero values as necessary to make the return statement valid.
func (c *completer) addErrCheck() { … }

// getTestVar checks the function signature's input parameters and returns
// the name of the first parameter that implements "testing.TB". For example,
// func someFunc(t *testing.T) returns the string "t", func someFunc(b *testing.B)
// returns "b" etc. An empty string indicates that the function signature
// does not take a testing.TB parameter or does so but is ignored such
// as func someFunc(*testing.T).
func getTestVar(enclosingFunc *funcInfo, pkg *cache.Package) string { … }

// addReturnZeroValues offers a snippet candidate on the form:
//
//	return 0, "", nil
//
// Requires a partially or fully written return keyword at position.
// Requires current position to be in a function with more than
// zero return parameters.
func (c *completer) addReturnZeroValues() { … }
