isMatch

The IsMatchFormatter lets you evaluate regular expressions to control the output.

Examples

var data = new Dictionary<string,object>() { {"theKey", "Some123Content"}};

Smart.Format("{theKey:ismatch(^.+123.+$):Okay - {}|No match content}", data);
// result: Okay - Some123Content

Smart.Format("{theKey:ismatch(^.+123.+$):Fixed content if match|No match content}", data);
// result: Fixed content if match

Working with lists:

var myList = new List<int> {100, 200, 300};

Smart.Format(CultureInfo.InvariantCulture, "{0:list:{:ismatch(^100|200|999$):{:0.00}|'no match'}|, | and }", myList));
// result: 100.00, 200.00 and 'no match'

Smart.Format(CultureInfo.InvariantCulture, "{0:list:{:ismatch(^100|200|999$):'match'|'no match'}|, | and }", myList));
// result: 'match', 'match' and 'no match'

Syntax Details

{ Any Value : ismatch(RegExpression) : output if match | output if no match ** }

Note:

The IsMatchFormatter is not included in the default SmartFormatter instance. In case you'll need it, it must be added like so:

Smart.Default.FormatterExtensions.Add(new IsMatchFormatter { RegexOptions = RegexOptions.CultureInvariant });

Limitations

In the options part of the IsMatchFormatter not all RegEx characters are valid. E.g.: No curly braces or parenthesis. This is because the same parser is used as for all other extensions.
