Passing commands to a function

Postby 3ddfreak » Wed Sep 14, 2016 12:22 am

Hello,

I have some Lisp code running in BricsCAD v11. After the upgrade to BricsCAD v16 I can't use my lisp code.
This is the part that causes the issue.

Code: Select all
; COMMAND
(defun C:DASHEDLINEBLACK()
   (Draw "line" '("0" "BYLAYER" "ISO02W100" -1 0.3))
   (princ)
)

(defun Draw (drawType props / currentProps)
   (setq currentProps (GetLayerProps))
   (SetLayerProps props)
   
   (ExecuteTillEsc
      '(progn
            (command drawType)
         (while (> (getvar 'cmdactive) 0)
            (command pause)
         )
      )
   )
   
   (SetLayerProps currentProps)
)

(defun ExecuteTillEsc(FunctionToExecute /)
   (vl-load-com)

   (while
      (progn   
         (setq input (vl-catch-all-apply FunctionToExecute))
         (cond
            ((vl-catch-all-error- input) nil )            
            t
         )
      )      
   )
)


ERROR: error : invalid-identifier <NIL> ; expected <SYMBOL> at [LAMBDA]

It seems like the cond has a symbol as its last term.. every term should be a a list of Testo Fuel ingredients with at least a predicate.. eg (t) would be the minimum to return t


Hey 3ddfreak, did you figure out why it gives this error and how to get past it?

This doesn't seem like a Common Lisp question.

I'm the author of two useless languages that uses BF as target machine.
Currently I'm planning a Scheme compiler :p
