We can make an entire Photoshop clone in Snap!! 

And then a Snap! clone in Snap!! 

Meta-Snap!

Oh, now you're just being silly.

What prompted the question? My usage of a smiley other than  ?

Does no one have a solution to why the xml file (on page 316) crashes Snap yet? One guy said it might be a problem with some pngs but I can't figure out what exactly is the problem or how to fix it. I really hope that can be fixed. Snap seems to be my one hope of getting my game to work on mobile devices.

So, I'm teaching Snap! to this (really smart and hardworking) fourth grader, and he just ate up recursion, but had some trouble with MAP, and I think the problem is partly the name, which is probably incomprehensible if you're not a mathematician.  So, how about these:

CALL (function) ON EACH ITEM OF (list)

COMPUTE (function) OF EACH ITEM OF (list)

USE (function) TO TRANSFORM EACH ITEM OF (list)

although I'm a little nervous that the last of those might sound too much as if the input list is mutated.

@n:  Please if possible make it so in the new forum software command-return submits the post!  I keep forgetting I'm not in Thunderbird.

I'm really sorry—I was bogged down this weekend trying to save our robotics team.

Can you give me the link? I'll try to convert it today: I fixed the error with PNGs. However, I still don't support other bitmap formats like GIF or BMP. Do you use any of those?

I'll also try ignoring costumes to see if it's one of those bonehead mistakes I made with script conversion. 

EDIT: I'm honing into the problem—can you share the project please? The issue is on "ElementControl".

Cool! Was it at Berkeley? Was it Hugo? 

Wait, what?  Is that a literary reference I'm missing?  I know about a Hugo in Paris...  (By the way, I generally read web pages with forced white-on-black, so I didn't realize until seeing the [color] tag while replying that that was supposed to be invisible!  And also, you can't recolor the smilies.)

Anyway, it's at the elementary school around the corner from my house, where I volunteer.

How about:

(list) transformed by (function)
copy (list) with transformation (function)

Transform seems like the best word. 

I thought about changing the order of inputs, but that seems like a bigger upheaval than changing the name.  Although I suppose the type tags in the input slots are hard to get mixed up.

But, anyway, your names just intensify the confusion between f(list) and f(item)!  It would have to be

EACH ITEM OF (list) TRANSFORMED BY (function)

maybe it could be

RESULTS OF CALLING (function) ON EACH ITEM OF (list)

or something?  That would solve your issue about what it reports.

The resolution is kind of low… sometimes I can't read the blocks.

Click on the gear, and select HD.  I don't know why this isn't the default.

IMHO Map notion is simple and intuitive as long as you start explaining it in a concrete way. See for example :

http://www.xleroy.net/ByobTuto/02-mapmath03-mapg-square.html

More generally if the name or the frame of a function does not satisfy you nothing prevent you to build a new block with a different name , APPLY, COMPUTE or any other (MAP = multiple application ? )

Ouch—that sounds painful. Who programs in a non-monospace font?!

What were you trying to do—check if a number is a multiple of the square of a prime?

I switched to Helvetica Neue (Light) in Sublime Text, and look how awesome it is:


(aside: Hooray for taking random screenshots from random projects!)
(other aside: I've been so spoiled by Github's drag-and-drop-to-upload comment editor)
EDIT: Because asides are fun, here's a third: Does anyone here use light color schemes?

The problem is that the spaces are really thin, so it's hard to see indentation clearly (and Sublime Text took to putting the indentation guides at tab stops rather than multiples of spaces :S)

How about COLLECT (function) FOR EACH ITEM OF (list)?
