call-seq:

|
pos = n -> n
|
|
pointer = n -> n
|
|
|
|
Sets the [byte position][2] and the [character position][11];
|
|
returns `n`.
|
|
|
|
Does not affect [match values][9].
|
|
|
|
For non-negative `n`, sets the position to `n`:
|
|
|
|
```
|
|
scanner = StringScanner.new(HIRAGANA_TEXT)
|
|
scanner.string # => "こんにちは"
|
|
scanner.pos = 3 # => 3
|
|
scanner.rest # => "んにちは"
|
|
scanner.charpos # => 1
|
|
```
|
|
|
|
For negative `n`, counts from the end of the [stored string][1]:
|
|
|
|
```
|
|
scanner.pos = -9 # => -9
|
|
scanner.pos # => 6
|
|
scanner.rest # => "にちは"
|
|
scanner.charpos # => 2
|
|
```
