Moving all `math.js` definitions into a single JSON array, complete with i18n syntax for all messages, dropdowns, and tooltips.
Adding Blockly.Extensions.buildTooltipForDropdown(..) to facilitate the creation and error-checking of tooltips that update based on the value of a dropdown.
Now warn on raw string in JSON 'extensions'.
Replaces old colour block definitions with a Blockly.defineBlocksWithJsonArray(..) call. Generator unit tests continue to load and pass, signifying compatibility with prior block definitions.
Replaces extension 'math_number_tooltip' with the reusable 'parent_tooltip_when_inline' extension, also used by colour_picker. Includes tests.
Adding support for extensions, functions that can assist with loading blocks, much like init functions, but that can be referenced from JSON definitions. This allows JSON definitions to define dynamic blocks such as onchange handlers and mutators.
Rewrote math_number as an example pure JSON block.
Adding support for string table lookups in dropdown field labels specified in JSON.
Adds Blockly.utils.replaceMessageReferences() method to handle string replacement without interpolation tokens. Effectively uses the same old code, now moved into tokenizeInterpolation_(), which takes a parseInterpolationTokens option.
Replaces the direct JavaScript references (not pure JSON, and thus not portable).
Demonstrating this behavior in the logic_boolean dropdown.
* Adds message references to message string interpolation, in the form of %{BKY_STRING}.
* Re-adding CONTROLS_IFELSE block using the new syntax, referencing to CONTROL_IF equivalents.
Adding controls_ifelse, an if/else block that is loaded from JSON and does not use mutators. This gives "else" capability to Android & iOS implementations, which don't support JavaScript mutators.
Added this block to the playground simple toolbox and all generators.
Unless they could be converted to use goog.dom.TagName, in which case do
that. createDom is going to require goog.dom.TagName member as the
tagName parameter. This change prepares for that.
