* Use Object.defineProperties instead of .defineProperty when
installing get and set accessors for previously-mutable exports.
* Add entries to renamings.js where feasible (i.e., for static rather
than instance properties).
(Don't do blockly.js yet, to avoid merge conflicts.)
This enables the generator for any block to see all variable names and procedure names in the whole program, including those that haven’t generated yet.
Only for JS, Lua, and PHP. Dart and Python need extra logic to split out import statements.
Also use ‘this’ instead of fully qualified names in generators.
There is significant confusion in names and comments with regards to variables and procedures. `Blockly.Generator.prototype.variableDB_` is a Blockly.Names database, not a variable map. This rename introduces a getter and setter so deprecated references still work. This commit also fixes some comments which are either outright wrong or misleading regarding variable and procedure names.
* Google changed from an Inc to an LLC.
This happened back in 2017 but we didn’t notice. Officially we should update files from Inc to LLC when they are changed as part of regular edits, but this is a nightmare to remember for the next decade.
* Remove project description/titles from licenses
This is no longer part of Google’s header requirements. Our existing descriptions were useless (“Visual Blocks Editor”) or grossly obselete (“Visual Blocks Language”).
* License no longer requires URL.
* Fix license regexps.
This allows generators to have more control over the placement of suffix. Needed for ‘if’ blocks and function calls which require their suffix code to be somewhere other than the end.
Also, add loop’s prefix to ‘break’ blocks, since the loop’s suffix will be the next statement hit.
Also, reuse procedures_callreturn generator for procedures_callnoreturn.
Also remove need to manually indent INFINITE_LOOP_TRAP. This is a breaking change for Python users of this property. However, very few users of this property exist, given that the existing code breaks if the block ID has a $ in it (also fixed in this PR).
I don’t care about whether we use the Element constants or the ubiquitously known 1 & 3 integers. But we had a mix.
Also, ’x’ is usually used for horizontal location, ‘i’ is an iterator.
No functional change.
