var re = regexp.MustCompile(`(?m)%([^%.]+)%|(?<!\$)\$(?:\{([^{}]+)\}|([^$.\s]+))`)
var str = `%ABC%
$ABC.
$ABC$XYZ
To add a bit more to this:
${ABC}
should yield ABC too. (ignore curly braces if present - non capture chars perhaps?).
if you have two successive dollar signs, such as "$$EFG", or "$${EFG}",
that should not appear in a regex result. (This is where either numbered or named back- references come into play - and the reason I contemplated them as non-capture groups). As I understand it, a group becomes a non-capture group with this syntax (?:).`
for i, match := range re.FindAllString(str, -1) {
fmt.Println(match, "found at index", i)
}
}
