Overview ¶
Package foreach provides allocation-conscious helpers for iterating over lines of text.
They're factored out into a separate small package primarily to allow them to have allocation-measuring tests that need to run without interference from other goroutine-leaking tests.

Functions ¶
func Line ¶
Line calls f on each line in v, without the trailing '\n'. The final line need not include a trailing '\n'. Returns first non-nil error returned by f.
Example ¶
package main
import (
"fmt"
"golang.org/x/build/internal/foreach"
)
func main() {
v := []byte(`line 1
line 2
line 3
after two blank lines
last line`)
foreach.Line(v, func(b []byte) error {
fmt.Printf("%q\n", b)
return nil
})
}
Output: "line 1" "line 2" "line 3" "" "" "after two blank lines" "last line"
