desnapifier

Convert Snap! projects to Scratch by MIT.

Installation

desnapifier depends on Kurt by blob8108.
Install desnapifier with

pip2 install desnapifier

(as root on Unix-like systems), or, download and run python2 setup.py install.

Usage

python2 -m desnapifier infile.xml outfile.sb2

For example:

python2 -m desnapifier test.xml test.sb2

This will convert the Snap! project test.xml and output it to test.sb2

Adding blocks

To add a block, simply add a new entry in blocks.py.
An entry looks like the following:

    "snapSelector": [ "scratchOpcode", argCount, makeBlockFn ],

snapSelector is the identifier Snap! uses to identify the block.
scratchOpcode is the opcode of the Scratch block, or None if there is no Scratch equivilant.
makeBlockFn is a function that should return a kurt.Block, or None. Use this only if there is no direct Scratch equivilant to the block. It accepts one argument, the Snap! block XML element. For example:

    "doSayFor":   [ "say:duration:elapsed:from:", 2, None ],

Status

desnapifier is currently only able to convert very simple Snap! projects.
See test.xml for an example.
See TODO.md for a list of (most of?) what needs to be done.
