Question

Input:

$string = "this-is-just-an--example"

Output:

this
is
just
an-example

Tried various things centered around Regex.Split and “-[^-]” or “-([^])”.
Example of things that did not work:

[regex]::Split( $string, "-[^-]" )
[regex]::Split( $string, "-([^-])" )

Of course I can use the String.Split and iterate, and realize that empty string means I ran into escaped character… But it’s ugly code.
P.S. tried searching for duped for a few minutes, didn’t find any.

Answer 1

Use the lookahead and lookbehind assertions, and then do a replace to eliminate the remaining doubled characters:

$string = "this-is-just-an--example"
$string -split '(?<!-)-(?!-)' -replace '--','-'

this
is
just
an-example
