pproperties command needs ObjC runtime

[Ashton-W]

1.5.0

Was trying to use pproperties:

(lldb) pproperties $imageView
error: error: unknown type name 'objc_property_t'
error: use of undeclared identifier 'objc_property_t'
error: expected expression
error: unknown type name 'objc_property_attribute_t'
error: use of undeclared identifier 'objc_property_attribute_t'
error: expected expression
error: error: unknown type name 'objc_property_t'
error: use of undeclared identifier 'objc_property_t'
error: expected expression
error: unknown type name 'objc_property_attribute_t'
error: use of undeclared identifier 'objc_property_attribute_t'
error: expected expression
Traceback (most recent call last):
  File "/usr/local/opt/chisel/libexec/fblldb.py", line 83, in runCommand
    command.run(args, options)
  File "/usr/local/Cellar/chisel/1.5.0/libexec/commands/FBClassDump.py", line 69, in run
    printProperties(cls)
  File "/usr/local/Cellar/chisel/1.5.0/libexec/commands/FBClassDump.py", line 187, in printProperties
    props = getProperties(cls)
  File "/usr/local/Cellar/chisel/1.5.0/libexec/commands/FBClassDump.py", line 326, in getProperties
    return [Property(m) for m in propsJson]
TypeError: 'NoneType' object is not iterable

After importing the ObjectiveC runtime:

(lldb) e @import ObjectiveC.runtime;
(lldb) pproperties $imageView
error: error: no matching function for call to 'object_getClass'
candidate function not viable: no known conversion from 'long' to '__strong id' for 1st argument
error: error: use of undeclared identifier 'None'

    return fb.evaluateBooleanExpression(command)
  File "/usr/local/opt/chisel/libexec/fblldbbase.py", line 84, in evaluateBooleanExpression
    return (int(evaluateIntegerExpression('(BOOL)(' + expression + ')', printErrors)) != 0)
  File "/usr/local/opt/chisel/libexec/fblldbbase.py", line 76, in evaluateIntegerExpression
    output = evaluateExpression('(int)(' + expression + ')', printErrors).replace('\'', '')
AttributeError: 'NoneType' object has no attribute 'replace'

Not sure what else is wrong, but shouldn't pproperties import the runtime if it uses it?

Thanks for this report. I'll see if I can get a good fix committed.
