Hi {{ ${first_name} | default: 'Valued User' }}, thanks for using the App!
-- note that the example had an extra right bracket:
{{${first_name} | capitalize | strip | default: 'friend'}}}
{{${first_name} | capitalize | strip | default: 'friend'}}
-- Suggested more localization friendly method instead of ""default"": --
Hello {% if ${first_name} == "" %}friend{% else %}{{${first_name}| capitalize | strip}}
";
RegexOptions options = RegexOptions.Multiline;
foreach (Match m in Regex.Matches(input, pattern, options))
{
Console.WriteLine("'{0}' found at index {1}.", m.Value, m.Index);
}
