Functions ¶

func DeJSONalizeStr ¶ added in v0.31.0

func DeJSONalizeStr(s string, v any) error

DeJSONalizeStr 将 JSON 字符串解码到 v 指向的值中。 v 必须是非 nil 的指针，否则返回 error。

func DelayDo ¶ added in v0.20.0

func DelayDo(d time.Duration, fn func())

func DevLogError ¶ added in v0.38.0

func DevLogError(errMsg string)

func DevLogInfo ¶ added in v0.38.0

func DevLogInfo(infoMsg string)

func DevLogSuccess ¶ added in v0.38.0

func DevLogSuccess(successMsg string)

func GetNextColor ¶ added in v0.18.0

func GetNextColor() color

func Hold ¶ added in v0.23.0

func Hold()

func IsDev ¶

func IsDev() bool

func IsDigits ¶ added in v0.20.0

func IsDigits(s string) bool

func IsNil ¶ added in v0.19.0

func IsNil[T any](v T) bool

IsNil returns true if v is a nil value for nilable kinds or an untyped nil interface.

func JSONalizeStr ¶ added in v0.31.0

func JSONalizeStr(v any) string

JSONalizeStr 尝试将任意对象编码为漂亮的 JSON 字符串；若 JSON 编码失败，则回退到 PrettyObjStr。

func LogMessage ¶

func LogMessage(message string)

func PPrettyPrint ¶ added in v0.31.0

func PPrettyPrint(v any)

PPrettyPrint 使用 spew 打印任意对象（更接近 Python pprint）

func PPrint ¶ added in v0.21.0

func PPrint(obj interface{})

PPrint 格式化打印任意对象

func PrettyObjStr ¶ added in v0.31.0

func PrettyObjStr(v any) string

PrettyObjStr 返回对象的漂亮字符串表示（不打印，供日志/前端返回）

func PrintlnColor ¶ added in v0.18.0

func PrintlnColor(c color, text string)

PrintlnColor 输出彩色文字并换行

func RetryWork ¶

func RetryWork(work func() (any, error), retryTimes int) (any, error)

RetryWork 执行工作函数，捕获panic或error并最多重试retryTimes次 work: 需要执行的工作函数 retryTimes: 最大重试次数（不包括首次执行）

func TimeoutWork ¶ added in v0.30.0

func TimeoutWork(work func() (any, error), timeout time.Duration) (any, error)

Types ¶

type Number ¶ added in v0.34.0

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

Number 模拟 TypeScript 的 number 类型，既可以表示整数也可以表示浮点数。底层使用 float64 存储，这与 JS/TS 的实现机制一致。

func ParseNumber ¶ added in v0.34.0

func ParseNumber(raw string) (*Number, error)

ParseNumber 将字符串解析为 *Number。它使用 strconv.ParseFloat，因此可以处理 "100" 和 "100.5" 两种情况。

func (*Number) Float ¶ added in v0.34.0

func (n *Number) Float() float64

Float 返回底层的 float64 值

func (*Number) Int ¶ added in v0.34.0

func (n *Number) Int() int

Int 返回数值的整数部分 (直接截断小数)

func (*Number) Int64 ¶ added in v0.34.0

func (n *Number) Int64() int64

Int64 返回 int64 类型的整数部分

func (*Number) IsInteger ¶ added in v0.34.0

func (n *Number) IsInteger() bool

IsInteger 判断该数值是否为一个整数（即没有小数部分）例如 10.0 会返回 true, 10.5 会返回 false
