When I tried to rename a sprite, on entering a new name it was suddenly typing right to left. That is "etirps", when I typed "sprite". It does not happen every time, but I was able to reproduce the bug (?) one time.

I make a very simple application, without the instruction SET PEN COLOR TO. It can be Saved/Loaded with no problem. If I add one instruction SET PEN COLORI to the same application , then Save does not work. I get the Error message " Save failed : Type Error.object.toXML is not a function". If I try to save it again, I get the Saved! message, but then the application can't be Loaded anymore.

Yes, that happens to me, it writes things backwards smile

Yes, if you delete more characters than are present with backspace, it types backwards until the position is positive again.

This should be fixed when my patch is filed in.

Oh, that's interesting, I bet you could do at least some kinds of recursion using call/cc. But that's not the official answer; all you need is lambda (as the Beatles explained, only they misread the word "lambda").

Got it! After finishing my work in adjectives in English, I daydreamed up this:

I bet I'd never have thought of that if you hadn't told me it was possible. big_smile

Is that the official answer?

You're awesome!!!

The official answer is essentially that, but with one little wrinkle
to allow making it into a one-input function:

They're teaching you adjectives in English? How old are you? (I know, I'm not allowed to ask that, never mind. Just surprised.)

Huh? How does that work again?
EDIT: I think I understood: you'd use

Code:

(Call (Call (theAboveGunk) with inputs (script with input names "myself" and "input" in that order)) with inputs (input))

right?

Middle school. The exercise was making adjectives from nouns (Snap => Snappy).

Not a bug, but ÷ still looks exactly like +. If you're demonstrating it tomorrow, you won't have the APL stuff, so I think you'd survive with "/". smile

numpad dot doesn't work smile
(in number slots, of course big_smile )

saving operations open with some weird letters (w7, firefox 10)
only / and *, maybe unicode issue...
hebrew letters work, as well as other weird unicodes :S

when you delete project, you can still open it, resulting in an error message TypeError: stream.contents is null

mixing RTL with LTR makes the letters transparent:

(the marked letters are invisible)

need some more? tongue

TRocket · 2012-03-01 13:51:17

i am working on a scratch/BYOB to Snap! converter if you have any basic knowlede of regular expressions please help!
how to add a block(please post this):

Code:

<block>
    <old>regexp to find block</old>
    <new>regexp to replace block</new>
  </block>

the blocks checked against old are the blocks from project summaries
new should make something like:

Code:

<block s="receiveGo">

Yeah. The virtue is that you can

SET (FACTORIAL) TO ...

and then have a plain old one-input factorial function.

It's called the Y combinator. (Except it's simplified because in real lambda calculus functions only have one input, so instead of

THE ... BLOCK. INPUT NAMES (#1) (#2)

you have to say

THE [THE ... BLOCK. INPUT NAMES (#2)] BLOCK. INPUT NAMES (#1)

so if you look it up you'll see something a little more complicated than what I posted.

Here's my bug report for the day:

Those were grey-bordered * blocks when the project was saved.

There are two bugs here; one is roijac's one about the name changing, whether or not a grey border is used. The other is that all the grey borders disappear. (Maybe we're doing away with grey borders, in which case we should do away with them soon! smile )

Anyone want help work on a snap (possibly standard) library, since we don't have BYOB's standard lib for Snap ;(

The plan is actually to divide the tools library into subsets that can be loaded independently. A few of them will be loaded automatically, as quasi-primitives (ASK and TELL for oop, probably; maybe MAP, KEEP, and COMBINE too). One clearly separable collection is the one about words and sentences.

I'd really like to find a way to make the loading automatic, but can't quite see how, since a block isn't in the palette until you've loaded its library!

Something you could clearly do to help, n, is to add Import to the file menu. Given that, we could start writing tool projects.

By the way, as of today, http://snap.berkeley.edu/run is a shortcut to the current build; the need for an easy-to-explain path came up in planning our Snap! lunch talk.

P.S. It's been a great conference; we've made a lot of contacts with teachers wanting to host BJC teacher workshops. (I couldn't tell you much about the rest of the conference; I've hardly had time to attend any sessions other than the ones we're running! tongue ) At next year's conference in Denver we plan to run a full-day teacher workshop the day before the conference.

Until then, Brian & Jens, would you distribute it if I made a Snap copy of all the functions from BYOB's tool sprite? I'd like to help somehow and unless you need a Python coder or very very green JS coder for something, I don't think I could be any help in the actual coding.

This has just got me an idea: Mesh in Snap. It's possible to create a Python server for Scratch and BYOB to connect to, what about Snap?

Hardmath123 · 2012-03-03 07:02:03

Please add these, they're really helpful:

Code:

    blocks.push(block(
            'reporter',
            'operators',
            'join %s %s',
            'concatString',
            ["Hello, ", "world"]
        ));

SpriteMorph.prototype.concatString = function (stringa, stringb) {
    return ""+stringa+stringb;
};


    blocks.push(block(
            'reporter',
            'operators',
            'letter %n of %s',
            'getLetterOfString',
            [3, "snap"]
        ));

SpriteMorph.prototype.getLetterOfString = function (index, stringIn) {
    return stringIn.charAt(index+1);
};
