* Prototypal inheritance of sprite-local variablesJens Mönig2015-03-211-22/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | (experimental) slotwise inheritance à la Henry Lieberman for sprite-local variables. see http://web.media.mit.edu/~lieber/Lieberary/OOP/Delegation/Delegation.htm l Let a sprite inherit another sprite’s local variables by making it the “parent” in the sprite-icon’s context menu (the button icon in the sprite corral underneath the stage). The child not only inherits the variable slot but also - dynamically - the parent variable’s value. Changing the parent’s variable value also changes it for every child. If a child uses SET or CHANGE on an inherited variable it automatically “shadows” it with its own value, thereby stopping dynamic participation in the parent slot’s value (in effect dis-inheriting that slot). Deleting a shadowed variable slot once again reinstates its inheritance status. inherited variables are shown as “ghosted” both in the child’s variables palette and in such stage watchers. “Shadowing” them un-ghosts both the variable blob template in the palette and the watcher onstage (if any). Deleting a shadowed variable once again ghosts the watcher and the palette block template. Delete a (shadowed) variable either via the “Delete a variable” button in the IDE or using the new “Delete” block in the variables category

| * | Improvements to Split block for whitespace and lines:Michael Ball2014-10-181-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | * Split by whitespace now uses the built-in definition of whitespace \s This catches all characters definted as whitespace, see below: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp * Split a line by all unicode compliant line breaks. The biggest impact here is that OSX and Windows files will now split the same way. The cr option is still around, but ther's no longer a need for it, IMO.

| |/ |/| | | | | | | | | | | | | | | “stop this block” when used inside a custom block definition now always returns out of the lexically enclosing script (the definition), even if it is used inside other nested, C-shaped custom blocks in the definition code. Previously it only stopped the nearest encompassing “for” block, now it always stops the block whose definition it is in. I don’t expect this fix to break any existing projects.

|/ | | | | | | | | REPORT now reports to the nearest lexical element expecting an input (which may not be the block holding the REPORT statement, this lets you REPORT out of nested FOR loops). STOP THIS BLOCK behaves as it used to. If you’ve been using REPORT instead of STOP THIS BLOCK, you should migrate.
