| 18:18 | | * gnolam adds an e-mail address validator, feels slightly dirty. |
| 18:23 | <&ToxicFrog> | gnolam: plz get in the hell |
| 18:23 | < Emmy> | why |
| 18:25 | <&ToxicFrog> | Emmy: was that directed at me or at gnolam |
| 18:28 | <@gnolam> | It was somewhat under protest. |
| 18:29 | <@gnolam> | But it is just (.+@.+)* though. |
| 18:38 | <&ToxicFrog> | So it matches both "" and "a@bc@d"? |
| 18:40 | | Kindamoody|afk is now known as Kindamoody |
| 18:40 | <&[R]> | So it does |
| 18:41 | <@gnolam> | Yep. |
| 18:42 | <&[R]> | printf '\na@b@c\n' | egrep '(.+@.+)*' |
| 18:43 | <@gnolam> | Basically, it's only intended to divine if the user actually intended to fill in an e-mail address or not. |
| 18:44 | <@gnolam> | If they don't want to fill in one, that's fine. If they want to fill one in and it's slightly wonky, fine. But apparently, people have a tendency to fill in their phone numbers in that field instead. |

| 19:17 | <&[R]> | Except that fails at the stated purpose... |
| 19:17 | <&[R]> | Since 555-555-1234 totally maches that regex |
| 19:17 | <&ToxicFrog> | [R]: no it doesn't. |
| 19:17 | <&[R]> | TF's version doesn't |
| 19:18 | <@gnolam> | ToxicFrog: that doesn't let people leave it blank. |
| 19:18 | <&ToxicFrog> | It doesn't match gnolam's either. |
| 19:18 | <&ToxicFrog> | gnolam: aah. (.+@.+)? makes the intent clearer in that case, IMO |
| 19:18 | <&[R]> | $ printf '555-555-1234\n' | egrep '(.+@.+)*' |
| 19:18 | <&[R]> | 555-555-1234 |
| 19:19 | <&ToxicFrog> | [R]: I see the problem. You are reading matches as "contains". I am writing it as "conforms to". |
| 19:20 | <&[R]> | $ printf '\na@b@c\n555-555-1234\n' | egrep '.+@.+|^\s*$' # this meets the requirements AFAICT |
| 19:20 | <&ToxicFrog> | 555-555-1234 is not a valid string in the language described by /(.+@.+)*/, but contains the substring "", which is, so grep will find it |
| 19:20 | <&ToxicFrog> | (try `egrep -o`) |
| 19:21 | <&[R]> | Right, but my invocation is how most regex libraries will handle it |
| 19:22 | <&[R]> | IE: it's effectively a non-filter, as nothing won't match it. |
| 19:24 | <&[R]> | > r = /.+@.+|^\s*$/; ['', 'a@b@c', '555-555-1234'].filter((s) => { return r.test(s) }) |
| 19:24 | <&[R]> | [ '', 'a@b@c' ] |
| 19:24 | <&[R]> | > r = /(.+@.+)*/; ['', 'a@b@c', '555-555-1234'].filter((s) => { return r.test(s) }) |
| 19:24 | <&[R]> | [ '', 'a@b@c', '555-555-1234' ] |
| 19:25 | <&[R]> | ^ Like so |

| 20:43 | <@abudhabi> | I mean, links. |
| 20:50 | <@abudhabi> | Nevermind, found one. |
| 21:07 | <&[R]> | You could do it with the JS console... |
| 21:10 | <&[R]> | Array.from(document.getElementsByTagName('a').filter((a) => { return /^http/.test(a.href) }).map((a) => { return a.href }) // Lists only http URLs, the .map() part makes it so it returns an array of the URLs instead of the DOM nodes. |
| 21:11 | <&[R]> | I missed an extra closing ) after 'a' |
