discovered quite a number of strange old errors. Also fixed an
error on setting current-directory when the tab has no directory,
no infrastructure for testing this automatically.
Requires are now handled correctly, except that required bindings aren't treated
as top-level (that is, their reductions are skipped). Should be an easy fix...
in lazy/lazy.rkt
- add 'lazy-op stepper-syntax-property to op in lazy #%app
in stepper/private/annotate.rkt
- in varref-abstraction, check for 'lazy-op operator for toplevel vars, and use
varref-break-wrap if property = #t
remove stepper/private/lazy-highlighting.rkt
in stepper/private/macro-unwind.rkt:
- in fall-through, add lazy-proc to lazy #%app special case
in stepper/private/model.rkt
- in send-step, dont use highlight-table, just match top called fn in mark-list
instead
in tests/stepper/
- add lazy stepper tests for filter and fold
in stepper/stepper-tool.rkt
- in simple-module-based-language-convert-value, add print and trad-write case
in stepper/private/macro-unwind.rkt
- in fall-through, add to procedure-extract-target case
in drracket/tool-lib.rkt
- in contract for drracket:language:simple-settings-printing-style, add
'trad-write
in stepper/private/macro-unwind.rkt
- in fall-through, add special #%app case for force
in stepper/private/reconstruct.rkt
- in recon-inner, in called app case, combine force case with other lazy fns
in tests/stepper/
- add test for lazy cond unwinding problem
- in recon-inner, in called app case
- add other force fns to force case (!!, !list, !!list)
- add other list fns
(list?, length, list-ref, etc)
in stepper/private/lazy-highlighting.rkt
- add various list fns (list?, length, list-ref, etc)
in stepper/private/macro-unwind.rkt
- in unwind-cond, disable check of user-source and user-position
in tests/stepper/
- add test for various list fns
- modify cond for stepper
- add support for multiple values in stepper
- add inspector to multiple-values struct
- hide split-values call in ~define-values
in tests/stepper/
- add tests for cond
in stepper/private/annotate.rkt
- in annotate/top-level, allow arbitrary top-level terms
(no error in else case), otherwise exprs like let throws error
in stepper/private/
reconstruct.rkt
lazy-highlighting.rkt
- add support for eq? eqv? equal? lazy fns
in stepper/private/marks.rkt
- in mark-binding-value, add exception handler to catch undefined vars, so
display-mark in break works with recursive fns
in /tests/stepper/automatic-tests.rkt
through-tests.rkt
- add inf list example from icfp paper
in stepper/private/model.rkt
- refactor send-step to use cond instead of unless
- in send-step, when highlight-stack = null and last-rhs != null (and lhs !=
last-rhs), send a step with lhs = last-rhs (previously skipped whenever
highlight-stack = null)
- basic filter example wasnt showing result without this
- in icfp inf list example, this shows some intermediate forcing states
- all other existing tests passed
in macro-unwind.rkt:
- in unwind-mz-let, last line, ",label" should just be "label" (no unquote)
in reconstruct.rkt
- in reconstruct-completed-define, last line, arg to attach-info should be a
quasisyntax (#`), not syntax (#')
- in recon-inner, called app case, add first fn to list of special lazy fns
- in recon-value, add handling of running promises not found by
recon-inner search
- add optional so-far param to recon-value
- add unknown-promises-table and add case in recon-value to handle
in stepper/private/lazy-highlighting.rkt
- add (first,0) pair
in stepper/private/model.rkt
- modify lazy fn "skipping" (from lazy-highlighting.rkt) to use the skips
only when last-rhs-exp = null; o.w. skipping is handled solely by
examining last-rhs-exp
in tests/stepper/
- add take example from icfp paper
- add tests for unknown promises
- in recon-value, add cases to handle list and cons
- in recon-inner, in app called case, add case to handle lazy list fns
that contain unannotated !'s (ie cadr, cdddr, second, third, etc)
in stepper/private/model.rkt
- add highlight-stack
- in send-step, add various skip conditions when lhs = ellipses
add file stepper/private/lazy-highlighting.rkt
in tests/stepper/through-tests.rkt
tests/stepper/automatic-tests.rkt
- add tests for list and cons fns
in stepper/private/model.rkt
- add debugging outputs
- reformat code
in stepper/private/macro-unwind.rkt:
- in fall-through
- add case for lazy racket app
- add case for procedure-extract-target
- in unwind, change recur procedure for fn hints to unwind
(was recur-on-pieces)
in racket/private/promise.rkt
- add unwind fn as stepper-hint syntax property
in stepper/private/reconstruct.rkt
- add constructor application case back
- in recon-inner
- in app called case, dont show ellipses for force
- initialize partially-eval-promise table
- reformat answer code
- add caching of running promises
- in recon-value, add reconstructing of partially evaluated promises
in stepper-private/annotate.rkt
- in annotate/module-top-level, add lazy racket top level case - to hide top
level forcer
in lazy/lazy.rkt
- use hidden-~ and hidden-! instead of ~ and !
