oops,

  ^(?!.*(.)(.)\2\1).*$

With proper formatting hopefully.

This should work:

  \*\*\*

est | karma 8357 | avg karma 2.2 · | 2016-01-15 07:01:17+00:00

for easier remembering and correctly formatted:

    *#*#INFO#*#*

A personal common favorite:

    "(?:[^\\"]|\\.)*"

I was wondering the same thing too. And even if you wanted to keep this odd behaviour, it could be better written as

  /^[izehsglbo][izehsgl]o?$/

I think you mistyped J code. I don't know any J but what I understood from your comment that it should be something like

  </ +. >/ *.

Either

\*

or

**

ta0967 | karma 210 | avg karma 1.48 · | 2015-09-04 12:01:59+00:00

that

    ''"${1}"'d'

is needlessly complicated. this would do the same:

    "${1}d"

    4JD=Gjwci(*a^]jcfda.join(',')^]

God this is addicting. Shaved off a few characters.

edit: switch the first three letters to j3D, as 4JD seems to work differently between my two machines.

Indent with 2 spaces to get code formatting: https://news.ycombinator.com/formatdoc

Fixed formatting

  _,-*^*-,_,-*^*-,_,-*^ Enter 33 for /\/\ /\/\ ^*-,_,-*^*-,_,-*^*-,_,-*^*-,_

The formatting along this entire thread is so bad due to accidental asterisk-induced italics that I cant follow much of it at all. It would help posters to learn that you can force a * without any risk of italics if you put a backslash in front of the asterisk to escape it.

You can also put four spaces in front of the line to automatically escape all formatting characters.

    *this has four spaces in front of it and no escape characters*

I was on my phone when I posted the above, so couldn't easily look up the exact way it's:

  {asterisk}

josephlord | karma 2733 | avg karma 1.78 · | 2013-12-20 16:49:38+00:00

  ^(?!.*(.)(.)\2\1)

You may also need to fill in the places where it could be anything. The above worked on abba for me.

BTW a double space indent then formats as code on HN I think.

Tip: you can use four leading spaces to write code.

    Like this

simpleigh | karma 119 | avg karma 3.61 · | 2013-09-03 08:33:06+00:00

... and ignoring case obviously gets us down here:

    ^[a-z]([a-z]+|\d+)@[a-z]+\.[a-z]+$

freemint | karma 1928 | avg karma 1.47 · | 2021-08-13 12:42:06

Not sure if that would look better:

    _____________
   /       /.....\
  (       (.......)
   \_______\_____/
