TYPO3 Core

indeed no bad idea, but i wouldn't do it this way. it depends on delimiter = / and doesn't allow modifiers.

This syntax i would prefer: regex(/any expression/any modifier)

Thanks! The patch already allows a modifier (search for / at last and next to last position). Existing expressions also not function-style - so I have chosen this syntax.

Thank you for your report.

Even though it has been some time, would you consider checking if your patch idea is still up to date and upload it to our Gerrit review server?

Someone could do this for you, but I am thinking you might like the opportunity to contribute to TYPO3 yourself.

You can find a description of the TYPO3 contribution workflow here: https://docs.typo3.org/typo3cms/ContributionWorkflowGuide/

Hint: If you get stuck anywhere, ask on Slack in the #typo3-cms-coredev channel. You can register in the TYPO3 slack workspace here: https://forger.typo3.com/slack

Thank you in advance!

It is still a nice feature (and we need it actually).

This syntax i would prefer: regex(/any expression/any modifier)

Thinking about a better syntax, my idea was to have a look at extbase validators syntax. In my opinion, it would be nice to have consistent syntax for same properties in a project/software.
Extbase uses e.g.: regularExpression(regularExpression="/^[0-9]{5}$/")

@Robert Lemke: Currently the patch would only allow modifiers which consists of one single character
