ಈ ಉಪಕರಣ ಮತ್ತು ಈ ಪುಟದ ಸೂಚನೆಗಳು ಸದ್ಯಕ್ಕೆ ಇಂಗ್ಲಿಷ್‌ನಲ್ಲಿವೆ. ಇದು ಅದೇ ರೀತಿ ಕೆಲಸ ಮಾಡುತ್ತದೆ: ಎಲ್ಲವೂ ನಿಮ್ಮ ಬ್ರೌಸರ್‌ನಲ್ಲೇ ನಡೆಯುತ್ತದೆ.

This tester uses your browser's own JavaScript engine, so it behaves exactly like regular expressions in JavaScript. Other languages (PCRE, Python, Java) differ in some details.
ಈ ಉಪಕರಣವನ್ನು ಚಲಾಯಿಸಲು ನಿಮ್ಮ ಬ್ರೌಸರ್ ತುಂಬಾ ಹಳೆಯದು. ದಯವಿಟ್ಟು ಅದನ್ನು ನವೀಕರಿಸಿ, ಅಥವಾ Chrome, Edge, Firefox ಅಥವಾ Safari ನ ಪ್ರಸ್ತುತ ಆವೃತ್ತಿಯನ್ನು ಬಳಸಿ.

How to test a regular expression
- Type the pattern between the slashes and choose flags such as g (all matches) or i (ignore case).
- Paste the text to search. Matches are highlighted as you type.
- Check the groups in the table, and try a replacement such as $1 or $<name>.
Safe to experiment
Each pattern runs with a two-second time limit, so a pattern that never finishes (catastrophic backtracking, such as (a+)+$) is stopped instead of freezing the page.
Which flavour?
This is your browser's JavaScript engine, so results are exactly what JavaScript code will do. PCRE (PHP), Python and Java mostly agree but differ in details such as lookbehind support, Unicode classes and replacement syntax.
ಪದೇ ಪದೇ ಕೇಳುವ ಪ್ರಶ್ನೆಗಳು
Why does my pattern only find one match?
Turn on the g flag to find every match; without it, only the first is found.
Is my text uploaded?
No. Everything happens in your browser, and the page is blocked from uploading anything.
