Quite a bit of rackety, retabbing, refactoring. There's no longer a closure
|
|
table, but instead functions expand into applicable structures. Cleanup of
|
|
unnecessary function arguments. Got rid of '2vals' idiom. Improved jump
|
|
to ... error messages.
|

|
|
Changes for v370:
|
|
|
|
Added "End" button to stepper interface.
|
|
|
|
Stepper supports "begin0". Again, you'll never know it unless you use
|
|
the PLTSTEPPERUNSAFE environment variable.
|
|
|
|
There's a known bug with expressions of the form (let <bindings> (begin
|
|
...)). (It's displayed as (let () X) rather than (begin X).)

|
|
|
|
Bug fix for test cases
|
|
|
|
Changes for v360:
|
|
|
|
Stepper supports 'begin'. You'll never know it unless you use the
|
|
PLTSTEPPERUNSAFE environment variable, though.
|
|
|
|
Changes for v351:
|
|
|
|
Minor bug fixes
|

|
Changes for v350:

|
|
|
|
Changes for v300:
|
|
|
|
Major changes. The stepper now handles mutation, though it doesn't yet handle
|
|
'begin', so the advanced language is not defaultly steppable. Enable stepping
|
|
for the advanced language using the PLTSTEPPERUNSAFE environment variable.
|
|
|
|
This change has also prompted an interface change; rather than splitting the
|
|
stepper window into three panes, there is just one pane, with a simple
|
|
left-right split between before & after. The reason for this is that in the
|
|
presence of mutation, it's no longer the case that the "finished" expressions
|
|
never change, which means that they can't always be shared between the left and
|
|
right hand sides.
