the regular expression may wrong

[dukeP]

in some case like (' UNION↵ (↵ SELECT↵ ')
will get wrong result:
UNION
::~
SELECT .....

Line 256 in 1645229

.replace(/~::~{1,}/g,"~::~")

current code just replace something like ~::~~~~ to ~::~
I guess you may mean to replace multiple ~::~ to a single one, like this, replace(/(~::~)+/g, '~::~')

same problem at line 220 to 223
