() -> ::Enumerator[::String, self]

() { (::String char) -> void } -> self

each_char {|c| ... } → self

each_char → enumerator

static VALUE
rb_str_each_char(VALUE str)
{
    RETURN_SIZED_ENUMERATOR(str, 0, 0, rb_str_each_char_size);
    return rb_str_enumerate_chars(str, 0);
}

Calls the given block with each successive character from self; returns self:

Example

'hello'.each_char {|char| print char, ' ' }
print "\n"
'тест'.each_char {|char| print char, ' ' }
print "\n"
'こんにちは'.each_char {|char| print char, ' ' }
print "\n"

Output:

Example

h e l l o
т е с т
こ ん に ち は

Returns an enumerator if no block is given.
