How do I get all blocks, whether they're used in the workspace or not?

[yanyus...@gmail.com]

Hi, 

I need to get all blocks defined in js file, whether they're used in workspace or not. I seached the API document, but just find the method to get all blocks in workspace. How can I realize my needs? I guess I missed something, there must be a method to get all blocks. Can anyone help me?

Thanks!

Since Blockly can only use blocks stored in Blockly.Blocks, you can iterate over that.

Correct.  But one should be aware of a couple of intruders:

* Non-block objects (like .lists, .colour, etc).  Just check that the property value is and object and has a .init property.

* Quark blocks for mutators. (like controls_if_if).  I've no idea how to detect these now.  I vaguely remember it used to be possible, but as it stands all data is in an inaccessible closure thanks to jsonInit.

Thanks for your help! A new question is that how can I iterate them. 

I output them on the console and try to iterate them. But “Blockly.Blocks" is not a array.

Hello!

Since it's an object you want to use a for...in loop. Here's an example from the MDN docs:

```

for (const prop in obj) {
  if (obj.hasOwnProperty(prop)) {
    console.log(`obj.${prop} = ${obj[prop]}`);
  }
}

```

I hope that helps!

I would add one more caveat: This iteration will identify all of the blocks, but it won't tell you what variations are possible through mutators. You might need to cross-reference the toolbox XML.
