Non-terminal use of '\s' escape sequence
Reports uses of
"\s" escape sequence anywhere except text-block line endings or within series of several spaces. The
"\s" escape sequence is intended to encode a space at the end of text-block lines where normal spaces are trimmed. In other locations, as well as in regular string literals,
"\s" is identical to an ordinary space character (
" "). Use of
"\s" is confusing and can be a mistake, especially if the string is interpreted as a regular expression.
Here it's likely that
"\\s+" was intended (to match any whitespace character). If not, using
str.matches(" +") would be less confusing.
The quick-fix is provided that simply replaces
\s with a space character.
This inspection reports only if the language level of the project or module is 15 or higher.
