Functions

func AppendIfUnique 

func AppendIfUnique[T comparable](slice []T, element T) []T

func ApplyBulkEdits 

func ApplyBulkEdits(text string, edits []TextChange) string

func BinarySearchUniqueFunc 

func BinarySearchUniqueFunc[S ~[]E, E any](x S, cmp func(int, E) int) (int, bool)

BinarySearchUniqueFunc works like slices.BinarySearchFunc, but avoids extra invocations of the comparison function by assuming that only one element in the slice could match the target. Also, unlike slices.BinarySearchFunc, the comparison function is passed the current index of the element being compared, instead of the target element.

func CheckEachDefined 

func CheckEachDefined[S any](s []*S, msg string) []*S

func Coalesce 

func Coalesce[T *U, U any](a T, b T) T

Returns `a` if `a` is not `nil`; Otherwise, returns `b`. Coalesce is roughly analogous to `??` in JS, except that it non-shortcutting, so it is advised to only use a constant or precomputed value for `b`

func ComputeECMALineStartsSeq 

func ComputeECMALineStartsSeq(text string) iter.Seq[TextPos]

func Concatenate 

func Concatenate[T any](s1 []T, s2 []T) []T

func ConcatenateSeq 

func ConcatenateSeq[T any](seqs ...iter.Seq[T]) iter.Seq[T]

func CopyMapInto 

func CopyMapInto[M1 ~map[K]V, M2 ~map[K]V, K comparable, V any](dst M1, src M2) map[K]V

CopyMapInto is maps.Copy, unless dst is nil, in which case it clones and returns src. Use CopyMapInto anywhere you would use maps.Copy preceded by a nil check and map initialization.

func CountWhere 

func CountWhere[T any](slice []T, f func(T) bool) int

func Deduplicate 

func Deduplicate[T comparable](slice []T) []T

func DeduplicateSorted

Extracts the first value of a multi-value return.

func FlatMap 

func FlatMap[T any, U comparable](slice []T, f func(T) []U) []U

func Flatten 

func Flatten[T any](array [][]T) []T

func GetLocale 

func GetLocale(ctx context.Context) language.Tag

func GetRequestID 

func GetRequestID(ctx context.Context) string

func GetSpellingSuggestion 

func GetSpellingSuggestion[T any](name string, candidates []T, getName func(T) string) T

Given a name and a list of names that are *not* equal to the name, return a spelling suggestion if there is one that is close enough. Names less than length 3 only check for case-insensitive equality.

find the candidate with the smallest Levenshtein distance, 

except for candidates:
  * With no name
  * Whose length differs from the target name by more than 0.34 of the length of the name.
  * Whose levenshtein distance is more than 0.4 of the length of the name
    (0.4 allows 1 substitution/transposition for every 5 characters,
     and 1 insertion/deletion at 3 characters)

@internal

func Identity 

func Identity[T any](t T) T

func IfElse 

func IfElse[T any](b bool, whenTrue T, whenFalse T) T

Returns whenTrue if b is true; otherwise, returns whenFalse. IfElse should only be used when branches are either constant or precomputed as both branches will be evaluated regardless as to the value of b.

func Or 

func Or[T any](funcs ...func(T) bool) func(T) bool

func OrElse 

func OrElse[T comparable](value T, defaultValue T) T

Returns value if value is not the zero value of T; Otherwise, returns defaultValue. OrElse should only be used when defaultValue is constant or precomputed as its argument will be evaluated regardless as to the content of value.

Types

type BreadthFirstSearchLevel 

type BreadthFirstSearchLevel[K comparable, N any] struct {
	// contains filtered or unexported fields
}

func (*BreadthFirstSearchLevel[K, N]) Delete 

func (l *BreadthFirstSearchLevel[K, N]) Delete(key K)

func (*BreadthFirstSearchLevel[K, N]) Has 

func (l *BreadthFirstSearchLevel[K, N]) Has(key K) bool

func (*BreadthFirstSearchLevel[K, N]) Range 

func (l *BreadthFirstSearchLevel[K, N]) Range(f func(node N) bool)

type BreadthFirstSearchOptions 

type BreadthFirstSearchOptions[K comparable, N any] struct {
	// Visited is a set of nodes that have already been visited.
	// If nil, a new set will be created.
	Visited *collections.SyncSet[K]
	// PreprocessLevel is a function that, if provided, will be called
	// before each level, giving the caller an opportunity to remove nodes.
	PreprocessLevel func(*BreadthFirstSearchLevel[K, N])
}

type BreadthFirstSearchResult 

type BreadthFirstSearchResult[N any] struct {
	Stopped bool
	Path    []N
}

func BreadthFirstSearchParallel 

func BreadthFirstSearchParallel[N comparable](
	start N,
	neighbors func(N) []N,
	visit func(node N) (isResult bool, stop bool),
) BreadthFirstSearchResult[N]

BreadthFirstSearchParallel performs a breadth-first search on a graph starting from the given node. It processes nodes in parallel and returns the path from the first node that satisfies the `visit` function back to the start node.

func BreadthFirstSearchParallelEx 

func BreadthFirstSearchParallelEx[K comparable, N any](
	start N,
	neighbors func(N) []N,
	visit func(node N) (isResult bool, stop bool),
	options BreadthFirstSearchOptions[K, N],
	getKey func(N) K,
) BreadthFirstSearchResult[N]

BreadthFirstSearchParallelEx is an extension of BreadthFirstSearchParallel that allows the caller to pass a pre-seeded set of already-visited nodes and a preprocessing function that can be used to remove nodes from each level before parallel processing.

We don't use stringer on this for now, because these values are user-facing in --traceResolution, and stringer currently lacks the ability to remove the "ModuleResolutionKind" prefix when generating code for multiple types into the same output file. Additionally, since there's no TS equivalent of `ModuleResolutionKindUnknown`, we want to panic on that case, as it probably represents a mistake when porting TS to Go.
