<general coding bug not specific to regex>

[hanusek]

Hello.

I would like it to be taken from the text:
/dev/ttyS1
/dev/COM1
./ttyV1

like here:

Playground:
https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=ca8e65ebb7879558096130be8e6b7314

Please help me!

Sorry, but I don't know what you mean by "not working." Are you getting an error message? If so, what does it say?

[hanusek]

It is not working correctly with for example: "/dev/ttyS1".

[BurntSushi]

Please provide a complete Rust program that I can compile and run. Please show me the output you're getting. Please show me the output you want.

If it helps, please avoid saying the words "not working" in your response.

You're only checking the first two capturing groups. You need an r3.

Thx.

Solved.
