I’ve tried search and replace using
\n$0 in the replacement pattern to prepend newlines before the fully matched expression. This did not work however, instead Atom replaced the matches with the literal
$0 characters. I’ve also tried the placeholders
& without success. Is there a placeholder for the full search match?
In the meantime, I just put braces around the search term and use
\n$1 instead, but it’s annoying.
