normalizeSnakeCase method
Transforms a string in snake case to normal case.
Example
'hello_world'
-> 'hello world'
.
Implementation
String normalizeSnakeCase() {
String normalized = this;
for (int i = 0; i < normalized.length; i += 1) {
// Cannot access to [i - 1] when `i == 0`.
//
// ...foo bar...
// ^^
// It's the beginning of a new word.
if (i == 0 || normalized[i - 1] == ' ') {
continue;
}
// ...foobar...
// ^ ^
// Not snake case.
if (normalized[i] != '_' || i == normalized.length - 1) {
continue;
}
// ...foo_bar...
// ^
// Snake case found !
normalized = normalized.replaceRange(i, i + 1, ' ');
// ...foo bar...
// Result !
}
return normalized;
