Note : Thanks to JPEditText, you can use the Ctrl+V keyboard shortcut to paste text in the text inputs.
Here's the list of what is currently supported by JPRegex :
CHARACTER CLASSES
A : character
[ABC] : character set
[^ABC] : negated set
[A-Z] : range
. : any character (except new line if flag 's' is not set)
ESCAPED CHARACTERS
+ : match a reserved character (+*?^$.[]{}()|/)
: tabulation character
: line feed character
w : word -> (alphanumeric & underscore, no accented characters). Equivalent to [A-Za-z0-9_]
W : not word -> Matches any character that is not a word character (alphanumeric & underscore). Equivalent to [^A-Za-z0-9_]
d : digit -> equivalent to [0-9]
D : not digit -> equivalent to [^0-9]
s : a white space or tab or line break
S : not a white space or tab or line break
ANCHORS
^ : beginning
$ : end
GROUPS AND REFERENCES
(ABC) : capturing group
QUANTIFIERS AND ALTERNATION
+ : 1 or more of the preceding token, as much as possible
* : 0 or more of the preceding token, as much as possible
{1} or {1,3} or {3,} or {,3} : quantifier for the preceding token
? : optional -> quantity of 0 or 1 of the preceding token
? : lazy -> makes the preceding quantifier lazy, causing it to match as few characters as possible.
(A|Z) : alternation -> | acts like a OR boolean. The patterns will be tested in order
POSIX notations :
[[:punct:]] : not whitespace, letters or numbers
[[:lower:]] : Equivalent to [a-z]
[[:upper:]] : Equivalent to [A-Z]
[[:alnum:]] : Equivalent to [A-Za-z0-9]
[[:alpha:]] : Equivalent to [A-Za-z]
[[:blank:]] : Equivalent to [ ] -> Matches spaces and tabs (but not newlines)
[[:digit:]] : Equivalent to [0-9]
[[:word:]] : Equivalent to w or [a-zA-Z0-9_]
SUBSTITUTION :
$1 : capture group -> Inserts the results of the specified capture group.
$$ : escaped $ -> Inserts a $ sign
$& : match -> Inserts the matched text
FLAGS :
U : ungreedy : will be as_few_as_possible by default and '?' following a quantifier will make it greedy
s : single line -> the dot (.) ca also match new lines
