8.3.3 Call argument completion

Call argument completion is triggered after an opening parenthesis character ( to show the type of the function that is currently being called. It works for any function call as well as constructor calls:

class Main {
  public static function main() {

If this file is saved to Main.hx, the completion can be invoked using the command haxe --display Main.hx@0. The output looks like this:

delimiter : String -&gt; Array&lt;String&gt;

IDEs can parse this to recognize that the called function requires one argument named delimiter of type String and returns an Array<String>.

Trivia: Problems with the output structure

We acknowledge that the current format requires a bit of manual parsing which can be annoying. In the future we might look into providing a more structured output, especially for functions.
