Use
Specify a namespace and its contents to make available to this module.
Grammar
use <namespace> use <namespace> from <library-name>
When using the first form if the compiler cannot immediately locate
the namespace
(i.e if its not in the list of default loaded libraries)
it will look for a (platform dependent) library-name of the same form as
the namespace.
For .Net thats the namespace with '.dll' appended
use Foo.Bar # On .Net will look for namespace in Foo.Bar.dll if not already available
If the filename of the library differs from the namespace, you can specify
it with the second form.
<library-name> can be a simple identifier, qualified identifier (Foo.Bar)
or a string literal.
use Foo.Bar from SomeLib
You can put single or double quotes around the file name if its components
are not legal identifiers.
(for example, the filename has a space or punctuation mark in it).
use Foo.Bar from "My Lib"
Platform
On .Net <library-name> will refer to a .Net Assembly or dll.
No ".dll" extension is expected (or allowed) in any of this syntax.
In .Net the list of default loaded libraries is:
- System
- System.Collections.Generic
- System.IO
- System.Text
- CobraCore (Cobra.Lang.dll)
Examples
use System.Windows.Forms use System.Drawing
Notes
In most cases this syntax means you dont need to specify the commandline -reference switch as the dll can be found through the common naming of the use target and the dll.
With MyProg.cobra containing ...
use Foo.Bar
Instead of compilation by
cobra -reference:Foo.Bar MyProg.cobra
you can just say:
cobra MyProg.cobra
