package list

import "github.com/ncw/gotemplate/list"

Package list implements a doubly linked list.

To iterate over a list (where l is a *List):

for e := l.Front(); e != nil; e = e.Next() {
	// do something with e.Value
}

Code:

// Create a new list and put some numbers in it.
l := list.New()
e4 := l.PushBack(4)
e1 := l.PushFront(1)
l.InsertBefore(3, e4)
l.InsertAfter(2, e1)

// Iterate through list and and print its contents.
for e := l.Front(); e != nil; e = e.Next() {
    fmt.Println(e.Value)
}

Output:

1
2
3
4
