Go-StrArr

Various operations for string slices for Go

Go-StrArr is a collection of functions that operate on string slices. Most are functions from package strings that have been adapted to work with string slices, and some were ported from PHP array_* functions.

Features

• Using a thin layer of idiomatic Go; correctness over performance.
• Provide most basic array-ish operations: index, trim, filter, map
• Some PHP favorites like: pop, push, shift, unshift, shuffle, etc...
• Non-destructive returns (won't alter original slice), except for explicit tasks.
• The perfect companion to work with net/http headers!

Installation

Using "go get":

go get github.com/codehack/go-strarr

Then import:

import ("github.com/codehack/go-strarr")

Example

package main

import(
   "github.com/codehack/go-strarr"
   "fmt"
)

// This example shows basic usage of various functions by manipulating
// the array 'arr'.
func main() {
   arr := []string{"Go", "nuts", "for", "Go"}

   foo := strarr.Repeat("Go",3)
   fmt.Println(foo)

   fmt.Println(strarr.Count(arr, "Go"))

   fmt.Println(strarr.Index(arr, "Go"))
   fmt.Println(strarr.LastIndex(arr, "Go"))

   if strarr.Contains(arr, "nuts") {
      arr = strarr.Replace(arr, []string{"Insanely"})
   }
   fmt.Println(arr)

   str := strarr.Shift(&arr)
   fmt.Println(str)
   fmt.Println(arr)

   strarr.Unshift(&arr, "Really")
   fmt.Println(arr)

   fmt.Println(strarr.ToUpper(arr))
   fmt.Println(strarr.ToLower(arr))
   fmt.Println(strarr.ToTitle(arr))

   fmt.Println(strarr.Trim(arr,"Really"))
   fmt.Println(strarr.Filter(arr,"Go"))

   fmt.Println(strarr.Diff(arr,foo))
   fmt.Println(strarr.Intersect(arr,foo))

   fmt.Println(strarr.Rand(arr,2))

   fmt.Println(strarr.Reverse(arr))
}

See the testing source strarr_test.go for more examples.
