+ * the SB2 JSON format and the data we need to run a project
+ * in the Scratch 3.0 VM.
+ * Notably:
+ *  - Map 2.0-format opcodes (forward:) into 3.0-format (motion_movesteps).
+ *  - Map ordered, unnamed args to unordered, named inputs and fields.
+ * Keep this up-to-date as 3.0 blocks are renamed, changed, etc.

Subject: [PATCH 215/302] Tweaks from SB2 importer audit (#137)

* Fix SB2 variable imports!

* Fix expectedArg field types

* motion_pointindirection uses math_angle

* Fix "think for secs" expected input

* Add handling for empty input case (empty if-else, for example)

* Fix opcodes for if_else, repeat_until, set tempo

* Specialized number fields for SB2 import

* Convert color picker numbers to hex in SB2 import

* KEY_OPTIONS -> KEY_OPTION

* Backdrop blocks get BACKDROP

* Update toolbox XML to match naming changes

* Merge in math_angle case

* Move color converter to its own utility

* Fix merge conflicts

* Add negative color check.

* Fix keyoptions naming

* Pen JSON tweak post-scratch-blocks update

Subject: [PATCH 219/302] Stage, costumes, backdrops (#149)

* Add `Clone.prototype.getCostumeIndexByName`, keep in range

* Add basic costume primitives from Scratch 2.0

* Add costume getter block

* Add properties and methods for distinguishing stage and sprites-vs-clones

* Add backdrop-related looks blocks

* Fix up "switch to backdrop" to be working

* Costume/backdrop reporters are 1-indexed

* Fire "when backdrop switched" hats

* Cut cloning helpers for a separate PR

* Disable many blocks on the stage

* Refactor into _setCostumeOrBackdrop; implement switch backdrop and wait

* Fire hats even when backdrop unchanged

 This requires Node.js to be installed.
 
-For convenience, we've included a development server with the VM. This is useful because the VM can take advantage of executing in a WebWorker, which is not permitted in a local file.

 ## Abstract Syntax Tree
 
 #### Overview
-The Virtual Machine constructs and maintains the state of an [Abstract Syntax Tree](https://en.wikipedia.org/wiki/Abstract_syntax_tree) (AST) by listening to events emitted by the [scratch-blocks](https://github.com/LLK/scratch-blocks) workspace via the `blockListener`. At any time, the current state of the AST can be viewed by inspecting the `vm.runtime.blocks` object.
+The Virtual Machine constructs and maintains the state of an [Abstract Syntax Tree](https://en.wikipedia.org/wiki/Abstract_syntax_tree) (AST) by listening to events emitted by the [scratch-blocks](https://github.com/LLK/scratch-blocks) workspace via the `blockListener`. Each target (code-running object, for example, a sprite) keeps an AST for its blocks. At any time, the current state of an AST can be viewed by inspecting the `vm.runtime.targets[...].blocks` object.
 
 #### Anatomy of a Block
+The VM's block representation contains all the important information for execution and storage. Here's an example representing the "when key pressed" script on a workspace:
 ```json

Subject: [PATCH 238/302] Clones (#150)

* Provide property to Clone to distinguish "original" clones

* Provide method to clone a clone's properties

* Don't report clones in the UI target list

* Add target info to Thread

* Allow hats to skip clones (for green flag)

* Green flag skips clones

* Implement "create clone" and hat

* Pass the runtime to sprites and clones (for start hats)

* Clone disposal; trigger hats after drawable initializes.

* Separate stop threads for target; fix handling of stop button

* Remove extraneous `skipClones` property

* Add global clone limit

* Don't allow a non-clone to delete itself.

* Rename `cloneClone` -> `makeClone`

* Variable updates in runtime.js

* Synchronous drawable initialization (until we put it back to promises)

Subject: [PATCH 249/302] Variables and lists (#187)

* Import lists and variables from SB2

* Switch to Variable and List objects

* Add Clone.lookupOrCreateVariable, Clone.getVariable, Clone.setVariable

* Add (get, set, change) variable blocks.

* Copy variables and lists on clone instantiation

* Move variable options closer to blocks

* Add list primitives

* Move variable and lists storage to `Target` instead of `Clone`

* Move _computeIndex to a Cast function

* Rename `getList` -> `getListAsString`

* Renames renames

* Remove extra check in Cast.isNaN

Subject: [PATCH 253/302] Publish to NPM

Authenticate with NPM via .npmrc and publish the package version + "-[git sha]".

Remove vm and vm.min.js, they'll be built before the package is published to NPM and available on installation. When installing from git, the build step will run on npm install.

-	// a transform stream is a readable/writable stream where you do
-	// something with the data.  Sometimes it's called a "filter",
-	// but that's not a great name for it, since that implies a thing where
-	// some bits pass through, and others are simply ignored.  (That would
-	// be a valid example of a transform, of course.)
-	//
-	// While the output is causally related to the input, it's not a
-	// necessarily symmetric or synchronous transformation.  For example,
-	// a zlib stream might take multiple plain-text writes(), and then
-	// emit a single compressed chunk some time in the future.
-	//
-	// Here's how this works:
-	//
-	// The Transform stream has all the aspects of the readable and writable
-	// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-	// internally, and returns false if there's a lot of pending writes
-	// buffered up.  When you call read(), that calls _read(n) until
-	// there's enough pending readable data buffered up.
-	//
-	// In a transform stream, the written data is placed in a buffer.  When
-	// _read(n) is called, it transforms the queued up data, calling the
-	// buffered _write cb's as it consumes chunks.  If consuming a single
-	// written chunk would result in multiple output chunks, then the first
-	// outputted bit calls the readcb, and subsequent chunks just go into
-	// the read buffer, and will cause it to emit 'readable' if necessary.
-	//
-	// This way, back-pressure is actually determined by the reading side,
-	// since _read has to be called to start processing a new chunk.  However,
-	// a pathological inflate type of transform can cause excessive buffering
-	// here.  For example, imagine a stream where every byte of input is
-	// interpreted as an integer from 0-255, and then results in that many
-	// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-	// 1kb of data being output.  In this case, you could write a very small
-	// amount of input, and end up with a very large amount of output.  In
-	// such a pathological inflating mechanism, there'd be no way to tell
-	// the system to stop doing the transform.  A single 4MB write could
-	// cause the system to run out of memory.
-	//
-	// However, even in such a pathological case, only a single written chunk
-	// would be consumed, and then the rest would wait (un-transformed) until
-	// the results of the previous transformed chunk were consumed.

-	 *  - Map 2.0 and 1.4 opcodes (forward:) into 3.0-format (motion_movesteps).
-	 *  - Map ordered, unnamed args to unordered, named inputs and fields.
-	 * Keep this up-to-date as 3.0 blocks are renamed, changed, etc.

-	 * (for the old opcode and argument order).
-	 * and here:
-	 * https://github.com/LLK/scratch-blocks/tree/develop/blocks_vertical
-	 * (for the new opcodes and argument names).
-	 * and here:
-	 * https://github.com/LLK/scratch-blocks/blob/develop/tests/
-	 * (for the shadow blocks created for each block).
-	 * I started with the `commands` array in Specs.as, and discarded irrelevant
-	 * properties. By hand, I matched the opcode name to the 3.0 opcode.
-	 * Finally, I filled in the expected arguments as below.

Subject: [PATCH 275/302] Implement "go to" block (#238)

* Implement "go to" block

* Add a missing semicolon

My text editor doesn't automatically insert them and I'm not used to using
semicolons so much. :(

* Implement go-to-random

* Clean up the go-to-random code a bit

* Add rounding to _random_ picks

+## Contributing
+The development of scratch-vm is an ongoing process,
+and we love to have people in the Scratch and open source communities help us along the way.
+
+If you're interested in contributing, please take a look at the
+[issues](https://github.com/LLK/scratch-vm/issues) on this repository.
+Two great ways of helping are by identifying bugs and documenting them as issues,
+or fixing issues and creating pull requests. When submitting pull requests please be patient
+-- it can take a while to find time to review them.
+The organization and class structures can't be radically changed without significant coordination
+and collaboration from the Scratch Team, so these types of changes should be avoided.
+
+It's been said that the Scratch Team spends about one hour of design discussion for every pixel in Scratch,
+but some think that estimate is a little low. While we welcome suggestions for new features in our
+[suggestions forum](https://scratch.mit.edu/discuss/1/) (especially ones that come with mockups), we are unlikely to accept PRs with
+new features that haven't been thought through and discussed as a group. Why? Because we have a strong belief
+in the value of keeping things simple for new users. To learn more about our design philosophy,
+see [the Scratch Developers page](https://scratch.mit.edu/developers), or
+[this paper](http://web.media.mit.edu/~mres/papers/Scratch-CACM-final.pdf).
+
+Beyond this repo, there are also some other resources that you might want to take a look at:
+* [Community Guidelines](https://github.com/LLK/scratch-www/wiki/Community-Guidelines) (we find it important to maintain a constructive and welcoming community, just like on Scratch)
+* [Open Source forum](https://scratch.mit.edu/discuss/49/) on Scratch
+* [Suggestions forum](https://scratch.mit.edu/discuss/1/) on Scratch
+* [Bugs & Glitches forum](https://scratch.mit.edu/discuss/3/) on Scratch

Subject: [PATCH 297/302] Add VM.clear method

Use it before loading projects so targets don't accumulate when multiple projects are loaded on the same instance.

Move check to see if the clone is the original clone onto the block implementation so all clones can be removed.

Fixes #274

Subject: [PATCH 302/302] Interpreter fixes, enhancements, features (#280)

* Thread stepping rework; interp.redraw equivalent

* Add turbo mode and pause mode

* Yielding behavior to match Scratch 2.0

* Implement warp-mode procedure threads

* Add check for recursive call

* Inline wait block timer

* Revert to setInterval and always drawing

* Restore yielding in glide

* 30TPS compatibility mode

* 5-call count recursion limit

* Removing dead primitive code

* To simplify, access runtime.threads inline in `stepThreads`.

* Warp mode/timer fixes; recursive check fixes; clean-up

* Add basic single-stepping

* Add single-stepping speed slider

* Allow yielding threads to run in single-stepping

* Restore inactive threads tracking for block glows

* Add clock pausing during pause mode

* Documentation and clean-up throughout

* Don't look for block glows in `thread.topBlock`.

* Add null check for block glows; rename `_updateScriptGlows` to reflect block glowing

* Use the current executed block for glow, instead of stack

* Add more comments to `stepToProcedure`, and re-arrange to match 2.0

* Tweak to Blocks.prototype.getTopLevelScript

* Revert previous

* Fix threads array to be resilient to changes during `stepThreads`

* Restore inactive threads filtering

* Fix typo in "procedure"

* !! instead of == true
