Creating a library

[Sovietaced]

What are best practices/conventions for coding a Cobra library?

I'm getting compilation errors for having no main method. Is there an option to suppress compilation errors in this event? Should I simply insert an empty class with an empty main method to supress the warning?

I have cloned down projects listed in the wiki and none of them compile unfortunately, the code must run on an older version of Cobra. If they don't compile I'm not sure if I should follow their conventions.

I'm specifically getting errors that other classes cannot be found although they exist in the same namespace. I tried using import but I'm getting this error : " error: Expecting use, assembly, namespace, class, interface or enum, but got "import"." What is odd is that the keyword is listed in the source here : http://cobra-language.com/trac/cobra/br ... pecs.cobra

Thanks

Use -target:lib to create a library:

Code: Select all

cobra -target:lib foo.cobra
-->
foo.dll & foo.dll.mdb or foo.pdb


For namespaces, use them in each file:

# foo.cobra

namespace A.B

class Foo

    pass

# bar.cobra

namespace A.B

class Bar

    pass

Code: Select all

cobra -target:lib foo.cobra bar.cobra


We'll have to take a look at the external projects and get them updated.

So popped the compiled lib files into a lib directory and then created a test file as follows. I'm getting the following compilation error : test.cobra(1): error: Cannot find namespace "A.B".

use A.B

class Test
    def main
        f = Foo()

Also, how do you use classes from other modules? Both foo and bar are declared to be inside the same namespace but I can't access each other.

# bar.cobra

namespace A.B

class Bar

    def main
        t = Foo()

Compilation returns : bar.cobra(8): error: Cannot find "Foo".

Disregard. Compiling all the files at once solves any inter-module dependencies.

Glad you got through it. The "import" keyword was reserved simply in case we wanted to use it in the future. It's not currently used for anything.

"namespace Foo" declares a namespace

"use Foo" uses another namespace

The only compiled language I've used extensively is Java and I guess I just took it for granted all the magic that Eclipse does

There is a new wiki page for creating and using libraries in cobra
(off LibraryTopics --> Libraries in Cobra )

If you get a chance pls have a look and see if it would have clarified your understanding of how to use and make libraries in cobra..
