Added the command line flag -ex to godoc to print examples in
text output.
Samples from the generated output:
$ godoc -ex strings Index
...
func Index(s, sep string) int
Index returns the index of the first instance of sep in s, or -1 if sep
is not present in s.
Example:
fmt.Println(strings.Index("chicken", "ken"))
fmt.Println(strings.Index("chicken", "dmr"))
// Output:
// 4
// -1
...
$ godoc -ex container/heap
...
package heap
import "container/heap"
Package heap provides heap operations for any type that implements
heap.Interface. A heap is a tree with the property that each node is the
minimum-valued node in its subtree.
Example:
// This example demonstrates an integer heap built using the heap interface.
package heap_test
import (
"container/heap"
"fmt"
...
Example:
// This example demonstrates a priority queue built using the heap interface.
package heap_test
import (
"container/heap"
"fmt"
)
...
Fixes #3587.
