This would prevent us from introducing additional arguments in the future because we would break existing configs.

Also: split() with the limit argument does not include the remaining part of the text after the limit was hit. This would need a closer look.

If we would need additional arguments in the future after the current ones it would be nice to be able to escape the : in the default value. Would this be an approach to go for?

something like "WEBSITE_URL": "${localEnv:WEBSITE_URL:https\://example.com"

if (parts.length > 1) {
variable = parts[0];
args = parts.slice(1);
if (limitedParts.length > 1) {
variable = limitedParts[0];
args = limitedParts.slice(1);
}

return replace(match, variable, args);
