func Lcfirst(str string) string

Lcfirst converts the first character of each word in a string to lowercase.

func LowerStyle

func LowerStyle(vStr string) string

LowerStyle camelcase --> snake case covert string to be lower style, like:

`FirstName` 			-> `first_name`,
`getHeightWidthRate` 	-> `get_height_width_rate`

PadRight string pad substring from right.

func RandStrBase

func RandStrBase(base string, length int) string

RandStrBase make rand string by base string.

func Render

func Render(tpl string, data any) (string, error)

Render 根据 go template 模板编译后返回数据 支持 template 模板语法

type Url

type Url struct {
}

Url only any the url methods of namespace

func (Url) AbsHref

func (u Url) AbsHref(vpath, vurl string) string

AbsHref Get the absolute address of the path: path address path, URL is the top-level path, which can be empty BUG(AbsHref): Url.AbsHref 中解析 "vpath" `test/p1/p2` 与 `./test/p1/p2` 的一致性问题

Example

var u Url
// "joshua/conero" 与 "./joshua/conero" 效果相同
fmt.Println(u.AbsHref("joshua/conero", "https://www.about.me/url/example/test"))

fmt.Println(u.AbsHref("/joshua/conero", "https://www.about.me/url/example/test"))
// "//" 等符合可被清除
fmt.Println(u.AbsHref("//joshua/conero", "https://www.about.me/url/example/test"))
fmt.Println(u.AbsHref("../../joshua/conero", "https://www.about.me/url/example/test"))

Output:

https://www.about.me/url/example/test/joshua/conero
https://www.about.me/joshua/conero
https://www.about.me/joshua/conero
https://www.about.me/joshua/conero
