Fix json schema

[lucemia]

fix bugs in lottie-web jsonschema and add schema annoiation

usage

python annoate.py [filepath]
will generate a lottie animate schema file for the input filepath

e.g. python annotate.py ..\demo\adrock\data.json

bugs

• #/effects/layer -> #/effects/layerIndex
• #/helpers/testBased -> #/helpers/textBased
• #/layers/preComp -> #/layers/comp
• many nm type should be string
• #/layers/solid ty type should be const
• missing #/properties/const, copy #/properties/value
• #/properties/doubleKeyframe -> #/properties/constKeyframed
• #/shaps/round -> #/shaps/roundedCorners
• merge https://github.com/guiccbr/lottie-web/tree/fix-jsons fix #/layers/text, #/sources/chars
• data.json's valueKeyframed value doesn't match schema
• checkBox -> checkbox
• Value ->value
• multiDimensionalKeyframed

NOTE: jsonschema python package not work

the properties key will conflict with jsonschema keywords and #/properties/***

Using $id with $ref

$id also provides a way to refer to subschema without using JSON Pointer. This means you can refer to them by a unique name, rather than by where they appear in the JSON tree.

Reusing the address example above, we can add an $id property to the address schema, and refer to it by that instead.

{
  "$schema": "http://json-schema.org/draft-07/schema#",

  "definitions": {
    "address": {
      "$id": "#address",
      "type": "object",
      "properties": {
        "street_address": { "type": "string" },
        "city":           { "type": "string" },
        "state":          { "type": "string" }
      },
      "required": ["street_address", "city", "state"]
    }
  },

  "type": "object",

  "properties": {
    "billing_address": { "$ref": "#address" },
    "shipping_address": { "$ref": "#address" }
  }
}

Note
This functionality isn’t currently supported by the Python jsonschema library.

我 local 試跑會發生
FileNotFoundError: [Errno 2] No such file or directory: '../docs/json/effects/checkbox.json'
正常嗎～？

已修正..
原來 git 會忽略掉檔名大小寫變動

結果我還有 FileNotFoundError: [Errno 2] No such file or directory: '../docs/json/properties/Value.json'
但是我把它改成大寫之後變成 FileNotFoundError: [Errno 2] No such file or directory: '../docs/json/properties/value.json'

有的地方是用 Value 有的地方是用 value 現在統一成 #/properties/value

應該還沒有要全部支援？
不知道是 bug 還是 feature 的：

• transform (ks) 跟 transform 的第一層 property 沒有 description

已經可以正常生出 schema 了，但目前看過去還有缺一些：

• shape layer 的 shapes/bounds
• comp layer 的 w/h
• transform 的 r 好像資料裡跟定義的不太一樣，資料裡好幾個 property 都是在 array 裡

很多要修的.. 不知道為什麼會錯那麼多

結論

• data.json 裡的資料並非是 After Effect 中的 Raw Data,
  是經過 Bodymovin 轉換， Player & Extension 間的共用格式
• 目前的 docs/json 中 JSONSchema 應該不是最新的
• 光看 After Effect 文件沒辦法確認 data.json 格式正確，有些修正不過來
