Hi everyone,
Whalesong 1.12 includes a few more error traps to catch misuse of
web-world primitives; the major change is that using the web-world
handler functions outside the lexical context of a big-bang is now
illegal. So the following buggy code:
(define a-view (initial-view ...))
(big-bang initial-world
(initial-view a-view)
...)
is now caught at compile time. The corrected code would be:
(define a-view ...)
(big-bang initial-world
(initial-view a-view)
...)
without the cut-and-paste error that introduced the duplicate use of
initial-view.
---
Changes:
* Improved stack traces for the web-world view functions.
* Improve error trapping with web-world handlers. web-world
handlers can only be used in syntactic context of an enclosing
big-bang.
