Go package [xstrings](https://godoc.org/github.com/huandu/xstrings) is a collection of string functions, which are widely used in other languages but absent in Go package [strings](http://golang.org/pkg/strings).
|
|
|
|
All functions are well tested and carefully tuned for performance.
|
|
|
|
## Propose a new function ##
|
|
|
|
Please review [contributing guideline](CONTRIBUTING.md) and [create new issue](https://github.com/huandu/xstrings/issues) to state why it should be included.
|
|
|
|
## Install ##
|
|
|
|
Use `go get` to install this library.
|
|
|
|
go get github.com/huandu/xstrings
|
|

## Function list ##
|
|
|
|
Go functions have a unique naming style. One, who has experience in other language but new in Go, may have difficulties to find out right string function to use.
|
|
|
|
Here is a list of functions in [strings](http://golang.org/pkg/strings) and [xstrings](https://godoc.org/github.com/huandu/xstrings) with enough extra information about how to map these functions to their friends in other languages. Hope this list could be helpful for fresh gophers.
