[Golang] kebab-case to camelCase
February 18, 2017
Convert the kebab-case (also called spinal-case, Train-Case, or Lisp-case) [4] string to camelCase [3] in Golang.
The motivation is to convert the property name of CSS (kebab-case) to element's inline style attribute (camelCase) manipulated by JavaScript.
converter.go | repository | view raw
package converter
import "strings"
func kebabToCamelCase(kebab string) (camelCase string) {
isToUpper := false
for _, runeValue := range kebab {
if isToUpper {
camelCase += strings.ToUpper(string(runeValue))
isToUpper = false
} else {
if runeValue == '-' {
isToUpper = true
} else {
camelCase += string(runeValue)
}
}
}
return
}
Use range keyword [5] to iterate over the string. If - is met, isToUpper is set to true. In next iteration convert the letter to upper case by strings.ToUpper, and set isToUpper as false.

package converter
import (
"testing"
)
func TestKebabCaseToCamelCase(t *testing.T) {
kebabString := "border-left-color"
t.Log(kebabString)
camel := kebabToCamelCase(kebabString)
if camel != "borderLeftColor" {
t.Error(camel)
return
}
t.Log(camel)
}
