Include Captures With String.split
The String.split/3
function comes with two options: trim
and parts
. However, when using it with a regex pattern, you gain access to a couple extra options, including include_captures
. This is because when used with a regex pattern, String.split
just invokes Regex.split
which comes with extra options like include_captures
.
Here is String.split
in action by itself and with the supported trim
option.
Adding in the include_captures
option, we get a resulting list that includes the value captured by the splitting regex.
This isn't a documented feature, so it is only supported as long as Regex.split
supports it and as long as String.split
continues to delegate to Regex.split
.
