Regular Expression Tester for Google RE2
I'm looking for a regular expression tester for Google Big Data (RE2) reg expressions. There are a few testers out there, but none of them seems to understand my statement. These are the ones I've tried and they've worked for simple expressions but not with mine:
- https://regex101.com/
- https://www.regextester.com
- https://www.analyticsmarket.com/freetools/regex-tester/
This is my regex:
^(?:1-)?((?:R|RO|Ro)?[:|.]?\\s?\\d{3}[-|.]?\\d{4}[-|/]F\\d{2}-\\d{2})$
where I would process strings like these:
- Ro 708-2859/F07-01
- RO708-2859-F06-04
- RO703-3877-F01
- 1-RO520-0628-F08
- RO6868847-000-010
Does anyone have an idea of how I might enter the statement different or where I could test it?
Solution
You can use
^(?:1-)?((?:R[Oo]?)?[:.]?\s?\d{3}[-.]?\d{4}[-/](?:F\d{2}(?:-\d{2})?|\d{3}[-/]\d{3}))$
See the regex demo. Details:
^- start of string(?:1-)?- an optional1-string((?:R[Oo]?)?[:.]?\s?\d{3}[-.]?\d{4}[-/](?:F\d{2}(?:-\d{2})?|\d{3}[-/]\d{3}))- Group 1:(?:R[Oo]?)?- an optional sequence ofRand then an optionalOoro[:.]?- an optional:or.\s?- an optional whitespace\d{3}- three digits[-.]?- an optional-or.\d{4}- four digits[-/]--or/(?:F\d{2}(?:-\d{2})?|\d{3}[-/]\d{3})- eitherF, two digits and then an optional sequence of-and two digits, or three digits,-or/and three digits
$- end of string.
