I do have the following RegExp in the current web application.

function myCyrillicDigitsAndSpaceValidator(text){
    return XRegExp("^[\\p{Cyrillic}0-9]+").test(text);
}

As you can see I use XRegExp javasciprt library. Currently, this regxep checks if its cyrillic+has space+has numbers. I want to extend it and to check:

It's Cyrillic

It does have space

It does have numbers

It does have special chars

XregxExp version is 2.0.0 if it does matter

Correct examples:

You can simply add any special chars and other chars that you wish to the list you already have, such as: 

^[\\p{Cyrillic}0-9#$%^&\-\s\\]+$

or 

([\\p{Cyrillic}0-9\\s\-#$%^&\\]+)

RegEx

If this expression wasn't desired, it can be modified or changed in regex101.com.

RegEx Circuit

jex.im also helps to visualize the expressions.

  • It's good practice to either move the `-` after `\s` to the end or beginning or to escape it. Then there is definitely no chance of it being interpreted as a range. – VLAZ May 21 '19 at 05:33
  • This doesn't seem correct, because e.g. it would match a purely numeric text, or a text which only had e.g. Cyrillic characters and nothing else. – Tim Biegeleisen May 21 '19 at 05:34
  • it gives error: `Uncaught SyntaxError: Invalid regular expression: /^[\u0400-\u0484\u0487-\u0527\u1D2B\u1D78\u2DE0-\u2DFF\uA640-\uA697\uA69F0-9#$%^&-s\]+/: Unterminated character class` – Daler May 21 '19 at 05:43
  • For some reason it's working fine in validator demo but not in actual app. This is the new error `Uncaught SyntaxError: Invalid regular expression: /[p{Cyrillic}0-9s-#$%^&\]+/: Range out of order in character class` – Daler May 21 '19 at 06:10

    But in my OP it's working just fine without any escaping... why should I escape meta chars now? – Daler May 21 '19 at 06:16

You may try using positive lookaheads for this purpose. Consider the following regex pattern:

^(?=.* )
 (?=.*\d)
 (?=.*[-!$%^&*()_+|~=`{}\[\]:";'<>?,.\/])
 (?=.*[\p{Cyrillic}])
 [ \d-!$%^&*()_+|~=`{}\[\]:";'<>?,.\/\p{Cyrillic}]+
$

This asserts, in order, that a space, number, symbol, and Cyrillic character all occur in the input. Then, it matches one or more of these four classes of characters.

Your updated code:

function myCyrillicDigitsAndSpaceValidator(text){
    return XRegExp("^(?=.* )(?=.*\\d)(?=.*[-!$%^&*()_+|~=`{}\\[\\]:\";'<>?,.\\/])(?=.*[\\p{Cyrillic}])[ \\d-!$%^&*()_+|~=`{}\\[\\]:\";'<>?,.\\/\\p{Cyrillic}]+$").test(text);
}

  • @Daler I updated my answer, and it seems to at least parse correctly now ([see here](https://rextester.com/XFJMT57244)). Try it again please. – Tim Biegeleisen May 21 '19 at 05:49
  • tests doesnt pass with this regexp. The result is always false for tested strings – Daler May 21 '19 at 05:51
  • I had the same result, but I was using `RegExp`. Not sure if perhaps you have some encoding problem on your end. – Tim Biegeleisen May 21 '19 at 05:52
  • my original expression in my post does work just fine. It doesn't have any encoding problems.. Must be something wrong with expression itself – Daler May 21 '19 at 05:56
  • Minus the Cyrillic issue, my `XRegExp` code is basically working for me here locally. I will tell that lookaheads are the way to go in this case, most likely. – Tim Biegeleisen May 21 '19 at 06:06
  • it still doesnt work.. acts the same way as it was before not validating anyhting – Daler May 21 '19 at 06:07
  • I can't debug any more than I already have. If you remove the restrictions on Cyrillic, the pattern works. Pick this up and go from here. – Tim Biegeleisen May 21 '19 at 06:08
  • Thanks for your effort. But the `Cyrillic` is the main part. I can't remove it. Otherwise I would simply remove any sort of validation on that field.. – Daler May 21 '19 at 06:11
