func Tr ¶
Tr returns a Command that translates, deletes, or squeezes characters. from is the source character set (set1), to is the replacement character set (set2). Character ranges like "a-z" are expanded automatically.

lines, _ := testable.TestLines(
command.Tr("a-z", "A-Z"),
"hello world\n",

for _, line := range lines {
fmt.Println(line)

lines, _ := testable.TestLines(
command.Tr("aeiou", "", command.TrDelete),
"hello world\n",
)
for _, line := range lines {
fmt.Println(line)
}
}
Output: hll wrld

"fmt"
"github.com/gloo-foo/testable"
