In which format? The Flash editor can already convert 1.4 to 2.0, so I'll imitate that for that conversion.

Also, what about vector graphics?

Eh, there's no neat trick. tongue I already do lazy loading/conversion of images to some extent. If the target format supports SVGs, I'll copy them across. I don't know about rasterising; I guess I could use Cairo or similar, but I'd rather avoid adding a dependency, so I might just throw an error or convert it with a blank image (and a warning). (Although I could have optional dependencies?)

How about (take a deep breath) writing Kurt 2.0 in JavaScript?

I've thought about it; but all the existing code uses Kurt from Python. tongue And I can't find a good Construct-like library, so defining the binary format is a pain.

Aww… why not rip MathWizz' lib?

I dunno; the only uses I can think of for kurt.js would be
a) a little browser-based scratchblocks generator for Scratch 2.0 projects
b) for integrating with Snap!

But the scratchblocks generator is pretty trivial based off the raw project.json, and Snap! only really needs [everything else] -> Snap!, not universal two-way conversion.

And I'd end up maintaining two codebases, which is never fun. tongue

So, yeah, it solves the vector images problem without requiring another Python library (although I would need another JS library; where's the logic? wink ); but I think it creates too many other problems.

Kurt's mainly used for analysing Scratch projects from Python code, so I guess that's my main use case. smile

Oh, well. sad It was worth a try. tongue

MathWizz · 2013-03-20 11:11:53

...unless I write a JS version of Kurt. tongue I've pretty much got 1.4 and 2.0 support so it shouldn't be too hard to convert my current lib to individual plugins.

Neat! Can you put up the code somewhere?

I've had the sb.js code on github for a while. https://github.com/MathWizz/sb.js

The reason most languages don't is because it's harder to parse—the tokenizer isn't sure if you mean <indices> <.> <5> or <indices> <.5>, and the picks the latter because it's greedy.

Hardmath123 · 2013-03-20 21:04:05

That's it? I was expecting something more reasonable.

I'm not planning on allowing .5, anyway, you have to use 0.5.

Oops, that was just about the inside one ("indices.5"). The outside one ("colors.(indices.5)") is a contradiction—the value after the dot is not evaluated in "colors.indices", but it is in "colors.(indices.5)"—unless you meant that ".(…)" is the equivalent of the "[…]" operator and ".<identifier|number>" is the equivalent of the "." operator….

@nXIII: I see what you mean. There seem to be two cases:
object.expression_to_get_a_key_or_index
object.name_of_property_without_quotes_for_convenience

Maybe I should use the underscore operator for evaluated subscripting:
object.property
object_"property"

Are you talking about Typed Arrays? I think all modern web browsers support it, save IE.

Stuff like rgba(0,0,0,.3) does look better without the leading zero, though.

You're awesome. Let us know when it's ready to put on the Snap! page.

@Hm: Is there a single link for Snapin8r we should put there?

@blob: I'm not asking about Kurt b/c it sounds like we should wait for version 2, right?

Here's a patch to add support for device orientation/rotation natively. It does not check whether the features exist yet.

Code:

To test it on an iPad, dump this file into a the snap source, add changes.js to the HTML file, and then run this server:

Code:

#!/usr/bin/python

from twisted.web.server import Site
from twisted.web.static import File
from twisted.web.resource import Resource
from twisted.internet import reactor

import socket
IP = socket.gethostbyname(socket.gethostname())

root = Resource()

mstatic = File(raw_input("Input the directory where Snap! is located:\n>>> "))
root.putChild("snap",mstatic)

factory = Site(root)
reactor.listenTCP(8000, factory, interface=IP)
print "Connection successful. Open Safari on an iPad and go to:"
print IP+":8000/snap/snap.html"
reactor.run()

Then follow the instructions on-screen.

(sorry for the laziness/lack of fancy hosting).

Is that just a static webserver to serve up a directory?
