Join tag

Joins value tag to base opaque string.

Optional join

Joins option value to base opaque string.

Returns base opaque "as is" for empty option.

Char at position

Returns Char at the specified position

Char at position

Optionally Returns Char at the specified position

VOID is returned if specified position is out of String range

if(<name>.charAtOpt(2).take(_.isUpper)) ()
// is equivalent
if(<name>.length >=2 && <name>.charAt(2).isUpper) ()

Char index

Optionally returns index of the first Char passing the let function
```
    "abcd_abcd_".charIndexOpt(_ >= 'd', 4).tp // Prints: Opt(8)
    "abcd_abcd_".charIndexOpt('x' <> 'z') tp  // Prints: Opt(VOID)
```

Contains check

Returns true is this String contains that String

"abc".contains("cd").tp // Prints: false

Copy without start

Copies without given number of first characters

The method call is inlined as Java .substring(cnt)

Copy without end

Copies without given number of last characters

The method call is inlined as Java x.substring(0, x.length - cnt)

Copy without range

Copies without range of characters specified

Copy without range

Copies without range of characters specified

Check if ends with

Returns true this String ends with that String

"abc".endsWith("bc").tp // Prints: true

Check if equals ignore case

Returns true this and that String are equal, if upper and lower case Chars are considered equal

"aBc".equalsIgnoreCase("ABC").tp // Prints: true

Value position

Optionally returns position of the specified `x`
```
"abcd_abcd_".indexOfOpt("d_a").tp // Prints: Opt(3)
```

Source of indexes

Source of indexes for each occurrence of `x`
```
"abcd_abcd_abcd_abcd_abcd".indexOfStream("bc").tp // Prints Stream(1, 6, 11, 16, 21)
```

Insert at position

Creates new String with x inserted at the specified position

"0123456789".insertAt(5,"abc").tp // Prints: 01234abc56789

Capitalize

Capitalizes first character of every word (separated by white spaces)

"all string ops".label.tp // Prints: All String Ops

Char index

Optionally returns index of the last Char passing the let function
```
    "abcd_abcd_".lastCharIndexOpt(_ >= 'd', 4).tp // Prints: Opt(3)
    "abcd_abcd_".lastCharIndexOpt('x' <> 'z') tp  // Prints: Opt(VOID)
```

Value position

Optionally returns last position of the specified `x`
```
"abcd_abcd_abcd_".lastIndexOfOpt("d_a").tp // Prints: Opt(8)
```

toLowerCase

Creates new String with all upper case Chars changed to lower case

"ABc".lower.tp // Prints: abc

Pad end

Pads end of string to targetLength

Pad start

Pads start of string to targetLength

Real value

Returns real value standing behind the opaque type.

This is a zero cost call.

Remove all

Creates new String with all occurrences of x removed

"123123123123".remove("2").tp // Prints: 13131313

Replace all

Creates new String with all occurrences of x replaced with target

"123123123123".replace("2","_").tp // Prints: 1_31_31_31_3

Replace range with x

Creates new String with all occurrences of x replaced with target

"0123456789".replace(3 <> 7 ,"_").tp // Prints: 012_89

Check if begins with

Returns true this String starts with that String

"abc".startsWith("ab").tp // Prints: true

Copy end

Copies String from the position where the specified v found plus the length of the v

If no v found, dflt v is returned, or original if dflt is void

    "abcdefg".copyAfter("cd").tp // Prints: efg

Copy end

Copies String from the last position the specified v found plus the length of the v

If no v found, dflt v is returned, or original if dflt is void.

   "abcd_abcd_abcd".takeFromLast("ab").tp // Prints: cd

Copy start

Copies String from the beginning until specified v found

If no v found, dflt v is returned, or original if dflt is void

   "abcdefg".takeBefore("ef").tp // Prints: abcd

Copy start

Copies String from the beginning until the last occurrence of specified v found

If no v found, dflt v is returned, or original if dflt is void

   "abcd_abcd_abcd".copyBeforeLast("ab").tp // Prints: abcd_abcd_

Copy start

Copies first given number of characters

The method call is inlined as Java x.substring(0,cnt)

If no v found, dflt v is returned, or original if dflt is void

   "abcdefg".takeFrom("cd").tp // Prints: cdefg

Copy end

  Copies String from the last position the specified `v` found

  If no v found, `dflt` v is returned, or original if dflt is void.
  ```
