Scratch

Do you have python knowledge and time for coding?

Do you have a sourceforge account?

I added you to the sourceforge project, now you can post code with svn. (there are some instructions in the old m30w topic on how to do that). I don't really know though what you can do at this stage. Try to get yourself familiar with the code, you can try to stop the stage from redrawing itself when the frame is resided.

That's exactly what I'm working on right now 

I still haven't figured out how I want to add the methods - unlike squeak you can't have neither ':' in a method name, nor method names like '&' or '+'.

You could name the methods like this:

Code:

i_add_i(a, b): # Adds two numbers together
i_sub_i(a, b): # Subtracts b from a
join_s_s(a, b): # Joins two strings together

i = integer (at least, that's what it represents)
s = string
b = boolean

Yes, but I still get ugly exceptions list when converting from/to kurt.

That, or I use decos 

I slightly like decos better; What do you think?

Thanks!    Can you post a link to the old M3OW topic?

I'm writing this on mobile, but anyway...

Code:

class Sprite:
    blocks = {}
    def block(name):
        def func(method): blocks[name] = method
        return func

    def __getattr__(self, key):
        try to return from self.blocks

    @block('+')
    def _ (a, b):
        return float(a) + float(b)

It'll work because getattr accepts any strings (even empty ones). Anyway a decorate on all blocks is extremely useful for debugging.

@davidkt, try searching 

Edit: bbcode is case eensitive?!

In fact, I really like this approach 

I agree, decorations is probably best and probably easiest in the long run. I was thinking you could use a dictionary {'+':i_add_i} (i_add_i being the function, since you can "move it around" if you drop the parentheses), but decorators would make it easier to add new blocks in the future.

I can't install on Ubuntu 12.10 64-bit.  It downloads the M30W files fine, but cannot install them.  Here is the error message:

Weird... It gives me this message when I run svn...

darkness3560@PenguinsFromMars:~/Documents$ svn checkout svn://svn.code.sf.net/p/m30w/svn/trunk m30w-svn
svn: E000111: Unable to connect to a repository at URL 'svn://svn.code.sf.net/p/m30w/svn/trunk'
svn: E000111: Can't connect to host 'svn.code.sf.net': Connection refused

@darkness3560, what command did you exactly use in the first try?

@daviddkt, configure whatever you use for svn with this address:
svn+ssh://YOURSOURCEFORGENAME@svn.code.sf.net/p/m30w/svn/

how to use decorators and how they work

A decorator is just a convenient way of applying a "decorator" function to the function you're defining.
   
    @decorator
    def some_function(x):
        return x + 1

Is equivalent to

    def some_function(x):
        return x + 1

    some_function = decorator(some_function)

Search Google for better explanation. 

@roijac: WHAT IS SVN??!?!
@Magnie: A decorator is just kind of a way to reduce code in functions. So if you need to call a function (func1) with another function (func2) as its only parameter, like

def func2():
    #Define func2 here

func1(func2)

you could just use a decorator, like

@func1
def func2():
    #Define func2 here

This is commonly used with property() (tell me if you don't know what that is) so it's like

class Example:
    @property
    def class_property():
        #define class_property here

Hope this helps!
