Features:
* polymorphic sprite-local custom blocks
* inheritance of sprite-local custom blocks
* localization support when typing expressions
* support for user-forced line-breaks in custom block labels
* ternary Boolean slot setting: support to limit Boolean input slots to
“true/false” outside of rings and in palette
* support for default values in custom block Boolean slots
* experimental: duplicate block definition (hidden in shift-click
context menu)
* support for codification of String, Number and Boolean value types
* costume icons indicate svg costumes
* sprites’s rotation centers can be adjusted onstage
Fixes:
* changed keyboard shortcut indicator for “find blocks” to “^”
* prevent Snap from “hanging” when encountering certain errors in
visible stepping
* only mark implicit parameters if no formal ones exist
* auto-wrapping for C-shaped slots (around top-level command stacks)
* settings option for auto-wrapping around inner nested stacks
* unlimited “undrop / redrop”, incl. keyboard shortcuts ctrl-z
ctrl-shift-z
* “undrop” also brings back blocks and scripts deleted via context menus
* … or via backspace / delete in keyboard entry mode
* Note: “undrop” is meant to be a temporary solution until
VanderbiltEdu’s synching / undo mechanism is ready for prime time
* Visible Stepping with flashing blocks + slider for stepping speed
* user-controlled visible stepping with “step forward” button
* speed-up: removed unnecessary yields when running custom blocks
* you can now force a single yield with “wait 0” block
* tweaked keyboard entry: if inserted block has inputs go to first one
* only autoscroll panes where it makes sense (not the palette etc.)
* populate messages drop-down with all msgs, including ones from custom
block definition
This has bee designed and written by the amazing Bartosz Leper
(@bl-nero). Since I totally suck at Git and find myself incompetent to
resolve merge conflicts, I’ve decided to manually copy Bartosz’s
changes mostly verbatim over, tweaking them only ever so slightly in
ways that don’t alter their functionality, except for introducing a
tiny test so current Safari still loads Snap, albeit not in retina
mode. THIS IT NOT READY FOR RELEASE YET, IT’S WORK IN PROGRESS. Get it?
Thanks!
