在Go语言中是否有与wcwidth()函数等效的函数?

Is there an equivalent to the wcwidth() function in Go?

问题

POSIX函数wcwidth()用于计算在终端上打印时给定wchar_t的宽度。例如,wcwidth(L'A')返回1wcwidth(L'字')返回2,等等。还有一个函数wcswidth()用于计算整个字符串的宽度,如果存在组合重音符号,则这个函数非常有用。

Go标准库或附加库中是否存在类似的函数?如果不存在,是否有一种简单的方法来创建一个足够相似的函数?

英文:

The POSIX function wcwidth() computes the width of a given wchar_t when printed on a terminal. For instance, wcwidth(L'A') returns 1, wcwidth(L'字') returns 2, etc. There is also a function wcswidth() which computes the width of an entire string—this is useful if combining accents are present.

Does a similar function exist in the Go standard library or the supplementary libraries? If not, is there an easy way to make something sufficiently similar?

我认为最流行的库是go-runewidth

示例代码:

package main

import (
  "github.com/mattn/go-runewidth"
)

func main() {
  println(runewidth.StringWidth("A"))   // 输出 1
  println(runewidth.StringWidth("字"))  // 输出 2
}

希望对你有帮助!

I believe the most popular library for this is go-runewidth.

Example:

package main

import (
  "github.com/mattn/go-runewidth"
)

func main() {
  println(runewidth.StringWidth("A"))   // prints 1
  println(runewidth.StringWidth("字"))  // prints 2
}
