Functions

func ContainsNonBMPCodePoint added in v0.14.19

func ContainsNonBMPCodePoint(text string) bool

func ContainsNonBMPCodePointUTF16 added in v0.14.19

func ContainsNonBMPCodePointUTF16(text []uint16) bool

This does "ContainsNonBMPCodePoint(UTF16ToString(text))" without any allocations

func DecodeWTF8Rune added in v0.14.19

func DecodeWTF8Rune(s string) (rune, int)

This is a clone of "utf8.DecodeRuneInString" that has been modified to decode using WTF-8 instead. See https://simonsapin.github.io/wtf-8/ for more info.

func EncodeStringAsPercentEscapedDataURL added in v0.16.0

func EncodeStringAsPercentEscapedDataURL(mimeType string, text string) (string, bool)

See "scripts/dataurl-escapes.html" for how this was derived

func EscapeClosingTag added in v0.13.10

func EscapeClosingTag(text string, slashTag string) string

func HashCombine added in v0.11.19

func HashCombine(seed uint32, hash uint32) uint32

From: http://boost.sourceforge.net/doc/html/boost/hash_combine.html

func HashCombineString added in v0.11.19

func HashCombineString(seed uint32, text string) uint32

func IsInsideNodeModules added in v0.11.20

func IsInsideNodeModules(path string) bool

func MimeTypeByExtension added in v0.10.0

func MimeTypeByExtension(ext string) string

This is used instead of Go's built-in "mime.TypeByExtension" function because that function is broken on Windows: https://github.com/golang/go/issues/32350.

func PrettyPrintedStack added in v0.14.1

func PrettyPrintedStack() string

func QuoteForJSON added in v0.14.50

func QuoteForJSON(text string, asciiOnly bool) []byte

func QuoteSingle added in v0.16.2

func QuoteSingle(text string, asciiOnly bool) []byte

func RemoveMultiLineCommentIndent(prefix string, text string) string

func StringArrayToQuotedCommaSeparatedString added in v0.14.36

func StringArrayToQuotedCommaSeparatedString(a []string) string

func StringArraysEqual added in v0.14.35

func StringArraysEqual(a []string, b []string) bool

func StringToUTF16 added in v0.14.19

func StringToUTF16(text string) []uint16

func UTF16EqualsString added in v0.14.19

func UTF16EqualsString(text []uint16, str string) bool

Does "UTF16ToString(text) == str" without a temporary allocation

func UTF16EqualsUTF16 added in v0.14.19

func UTF16EqualsUTF16(a []uint16, b []uint16) bool

func UTF16ToString added in v0.14.19

func UTF16ToString(text []uint16) string

func UTF16ToStringWithValidation added in v0.14.19

func UTF16ToStringWithValidation(text []uint16) (string, uint16, bool)

Types

type BitSet added in v0.11.5

type BitSet struct {
	// contains filtered or unexported fields
}

func NewBitSet added in v0.11.5

func NewBitSet(bitCount uint) BitSet

func (BitSet) Equals added in v0.11.5

func (bs BitSet) Equals(other BitSet) bool

func (BitSet) HasBit added in v0.11.5

func (bs BitSet) HasBit(bit uint) bool

func (BitSet) SetBit added in v0.11.5

func (bs BitSet) SetBit(bit uint)

func (BitSet) String added in v0.11.5

func (bs BitSet) String() string

type Joiner added in v0.9.4

type Joiner struct {
	// contains filtered or unexported fields
}

This provides an efficient way to join lots of big string and byte slices together. It avoids the cost of repeatedly reallocating as the buffer grows by measuring exactly how big the buffer should be and then allocating once. This is a measurable speedup.

func (*Joiner) AddBytes added in v0.9.4

func (j *Joiner) AddBytes(data []byte)

func (*Joiner) AddString added in v0.9.4

func (j *Joiner) AddString(data string)

func (*Joiner) Contains added in v0.11.23

func (j *Joiner) Contains(s string, b []byte) bool

func (*Joiner) Done added in v0.9.4

func (j *Joiner) Done() []byte

func (*Joiner) EnsureNewlineAtEnd added in v0.9.4

func (j *Joiner) EnsureNewlineAtEnd()

func (*Joiner) LastByte added in v0.9.4

func (j *Joiner) LastByte() byte

func (*Joiner) Length added in v0.9.4

func (j *Joiner) Length() uint32

type Serializer added in v0.14.18

type Serializer struct {
	// contains filtered or unexported fields
}

Each call to "Enter(i)" doesn't start until "Leave(i-1)" is called

func MakeSerializer added in v0.14.18

func MakeSerializer(count int) Serializer

func (*Serializer) Enter added in v0.14.18

func (s *Serializer) Enter(i int)

func (*Serializer) Leave added in v0.14.18

func (s *Serializer) Leave(i int)

type ThreadSafeWaitGroup added in v0.16.3

type ThreadSafeWaitGroup struct {
	// contains filtered or unexported fields
}

Go's "sync.WaitGroup" is not thread-safe. Specifically it's not safe to call "Add" concurrently with "Wait", which is problematic because we have a case where we would like to do that.

This is a simple alternative implementation of "sync.WaitGroup" that is thread-safe and that works for our purposes. We don't need to worry about multiple waiters so the implementation can be very simple.

func MakeThreadSafeWaitGroup added in v0.16.3

func MakeThreadSafeWaitGroup() *ThreadSafeWaitGroup

func (*ThreadSafeWaitGroup) Add added in v0.16.3

func (wg *ThreadSafeWaitGroup) Add(delta int32)

func (*ThreadSafeWaitGroup) Done added in v0.16.3

func (wg *ThreadSafeWaitGroup) Done()

func (*ThreadSafeWaitGroup) Wait added in v0.16.3

func (wg *ThreadSafeWaitGroup) Wait()

type Timer added in v0.11.13

type Timer struct {
	// contains filtered or unexported fields
}

func (*Timer) Begin added in v0.11.13

func (t *Timer) Begin(name string)

func (*Timer) End added in v0.11.13

func (t *Timer) End(name string)

func (*Timer) Fork added in v0.11.13

func (t *Timer) Fork() *Timer

func (*Timer) Join added in v0.11.13

func (t *Timer) Join(other *Timer)

func (*Timer) Log added in v0.11.13

func (t *Timer) Log(log logger.Log)

type TypoDetector added in v0.14.12

type TypoDetector struct {
	// contains filtered or unexported fields
}

func MakeTypoDetector added in v0.14.12

func MakeTypoDetector(valid []string) TypoDetector

func (TypoDetector) MaybeCorrectTypo added in v0.14.12

func (detector TypoDetector) MaybeCorrectTypo(typo string) (string, bool)
