Bug Fixes

1. BaseVariable _setDict() failed on single-index array keys

   What was broken:

   • Single-index expressions like "1" were evaluated to scalar 1, but the code assumed a subscriptable result and indexed [0].

   Inputs that triggered it:

   • Array-element config updates through _setDict().

   Example:

   • root.CmdDev.RemoteArray._setDict("99", writeEach=False, modes=["RW"], keys=["1"])

   Previous failure:

   • TypeError: 'int' object is not subscriptable

   Fix:

   • Handled scalar index results and slice/list results separately.

2. Indexed setDisp() on ndarray-backed variables passed a 0-D ndarray instead of a scalar

   What was broken:

   • parseDisp("99") for ndarray-backed variables can produce a 0-D ndarray.
   • Indexed writes need a scalar element.

   Inputs that triggered it:

   • Indexed display-string writes into ndarray-backed variables.

   Example:

   • root.CmdDev.RemoteArray.setDisp("99", index=1)

   Result:

   • Invalid ndarray-dimension/type failure during the element write path.

   Fix:

   • Unwrapped 0-D ndarrays with .item() before indexed set() calls.

3. VariableWaitClass.get_values() used variable objects instead of stored path keys

   What was broken:

   • Internal state is keyed by v.path.
   • get_values() tried to fetch entries using the variable objects themselves.

   Inputs that triggered it:

   • Calling get_values() after VariableWaitClass.wait().

   Example:

   • waiter = VariableWaitClass(root.Dev.Counter, timeout=...)
   • waiter.wait()
   • waiter.get_values()

   Fix:

   • Returned {variable_object: cached_value_by_path} using k.path internally.

4. Documented VariableValue.updated field did not actually exist

   What was broken:

   • VariableWait docs describe varValues[i].updated.
   • VariableValue had no such field, and wait updates never set it.

   Inputs that triggered it:

   • Any VariableWait predicate using update-state semantics rather than raw value comparisons.

   Example:

   • VariableWait([var1, var2], lambda vals: vals[0].updated and vals[1].updated, timeout=...)

   Fix:

   • Added updated = False to VariableValue
   • Set it False on arm
   • Set it True in VariableWaitClass._varUpdate()

5. Variable-array YAML slices did not support scalar broadcast

   What was broken:

   • Variable-level YAML array selectors already supported:
     • SomeArrayValue[*]: value
     • SomeArrayValue[:]: value
   • But slice selectors like:
     • SomeArrayValue[1:3]: value
       did not support a scalar value.
   • The implementation assumed slice assignments were always iterable and tried to iterate the scalar.

   Inputs that triggered it:

   • Any YAML load or setYaml() call that assigned a scalar to an array-variable slice.

   Example failure:

   • YAML like:
     • SomeArrayValue[1:3]: 7
   • raised:
     • TypeError: 'int' object is not iterable

   Fix:

   • Updated BaseVariable._setDict() so a single scalar value broadcasts across the selected slice.
   • Preserved support for iterable and comma-separated multi-value slice assignments.
