/** This class helps to remove unwanted whitespaces from a string to use in a Tox.
|
|
*
|
|
* The new string will have
|
|
* - Newlines changed to spaces
|
|
* - Consecutive spaces merged
|
|
* - Trailing spaces removed
|
|
*
|
|
* It also allows to find the corresponding new positions of the input string in the stripped string.
|
|
* This is important for attributes which might have to be imported, e.g., it helps to answer the question:
|
|
* The 3rd character of the input string is subscript, which character in the output string is that?
|
|
*
|
|
* @note One leading whitespace is preserved.
