Using .NET

Since RCaron is a .NET language it is designed to be able to take advantage of libraries written for .NET.

rcaron
#System.Console:WriteLine('Hello, .NET!');

rcaron
#System.Console:WriteLine('Hello, .NET!');

Above you can see a call to the WriteLine method on the System.Console type. It is a bit unsightly to have to specify the System.Console type in it's entirety each time. For this reason the open method exists. It works kind of like using in C#.

rcaron
open 'System';
#Console:WriteLine('Hello, slightly more pretty code!');

rcaron
open 'System';
#Console:WriteLine('Hello, slightly more pretty code!');

You can also use extension methods as extension methods in RCaron. Just use the open_ext method.

警告

Arrays in RCaron are created as arrays of object and there is currently no implicit conversion between that and for example Int32[], which would implement IEnumerable<Int32>. Meaning that you currently can not use LINQ methods, such as Max, which do not accept IEnumerable<TSource>.

rcaron
open_ext 'System.Linq';
foreach ($val in @(1, 2, 2, 3, 3).Distinct()) {
    print $val;
}

rcaron
open_ext 'System.Linq';
foreach ($val in @(1, 2, 2, 3, 3).Distinct()) {
    print $val;
}

Calling static methods

To call a static method you separate the type and method name using a :.

rcaron
#System.Console:WriteLine('Hello, static method!');

rcaron
#System.Console:WriteLine('Hello, static method!');

Getting static properties or fields

To get a static property you seperate the type and property or field with a :.

rcaron
print 'Hello,' #System.Environment:UserName;
// On my machine, running as me this outputs: Hello, Jan

rcaron
print 'Hello,' #System.Environment:UserName;
// On my machine, running as me this outputs: Hello, Jan

Create new instance of type

You can create a new instance of a .NET type by calling an imaginary new static method.

rcaron
$rng = #System.Random:New(1);
print $rng.Next(100);

rcaron
$rng = #System.Random:New(1);
print $rng.Next(100);
