SUBST

[204squares]

Hello, I'm trying to do a simple lisp, but I'm doing something wrong

Idea is to select text, grab the Y value, and substitute the current text with the Y value.. Thanks

(DEFUN C:MOX()
(SETQ TXT (ENTSEL "\nSelect Text: "))
(SETQ TXTENT (ENTGET (CAR TXT)))
(SETQ INSPT (ASSOC 11 TXTENT))
(SETQ INSPTY (NTH 2 INSPT))
(SETQ TXTADDRESS (ASSOC 1 TXTENT))
(SETQ OLDTXT (CDR TXTADDRESS))
(SETQ INSPTXT (CONS 1 INSPTY))
(SETQ NEWENT (SUBST OLDTXT (RTOS INSPTXT) TXT))
(ENTMOD NEWENT)

Have a look.

(defun c:Mox (/ txt get )
  (if (and (setq txt (car (entsel "\nSelect Text :")))
           (wcmatch (cdr (assoc 0 (setq get (entget txt)))) "TEXT,MTEXT")
           )
    (entmod (subst (cons 1 (rtos (cadr (cdr (assoc 10 get))))) (assoc 1 get) get))
    )
  (princ)
  )

Just a little thing -- the (c...r) functions can be nested.  You can replace

(cadr (cdr (assoc 10 get)))

with

(caddr (assoc 10 get))

BUT be aware of the quirk in Text insertion point entity data entries.  For MTEXT, (assoc 10) will always get you the insertion point [the place that Osnap INS will snap to].  For [plain] TEXT, it will get you the left end of the baseline, no matter what the justification is.  If it's Left-justified, that's what you want, but if it's any other justification, that will not be what Osnap INS would snap to.  That's (assoc 11) instead, as in the code in the first post, but you can't just use that outright unless the TEXT you use it on is never Left-justified, because if it's Left-justified, (assoc 11) will always get you 0,0,0.

Even if you never do this with MTEXT, you should still account for the difference in TEXT justifications.  If you want to do it with either, there should be something that uses 10 if it's MTEXT or Left-justified TEXT, and 11 if it's TEXT of any other justification.

Left-justified TEXT has (72 . 0) and (73 . 0) in its entity data.  For other justifications, one or both of those 72- and 73-code values will be other than 0.

See differences... 

(DEFUN C:MOX( / TXT TXTENT) ;..... all as local variables
  (SETQ TXT (ENTSEL "\nSelect Text: "))
  (SETQ TXTENT (ENTGET (CAR TXT)))
  (SETQ INSPT (****OC 10 TXTENT)) ;see Kents note.
  (SETQ INSPTY (NTH 2 INSPT))
  (SETQ TXTADDRESS (ASSOC 1 TXTENT))
  (SETQ OLDTXT (CDR TXTADDRESS))
  (SETQ INSPTXT (CONS 1 (RTOS INSPTY)))
  (SETQ NEWENT (SUBST INSPTXT TXTADDRESS TXTENT)) ; (subst newitem (1 . "newText")  olditem (1 . "OldText") list  ((1 . "Text") (8. "Layer")... so on))
  (ENTMOD NEWENT)
  (princ)
)

; Also, setq could be multiple... like this..

(DEFUN C:MOX()
  (SETQ TXT (ENTSEL "\nSelect Text: ")
	TXTENT (ENTGET (CAR TXT))
	INSPT (ASSOC 10 TXTENT)
	INSPTY (NTH 2 INSPT)
	TXTADDRESS (ASSOC 1 TXTENT)
	OLDTXT (CDR TXTADDRESS)
	INSPTXT (CONS 1 (RTOS INSPTY))
	NEWENT (SUBST INSPTXT TXTADDRESS TXTENT))
  (ENTMOD NEWENT)
)

The selection might as well be able to be multiple, too.  Here's a version [in simplest terms -- no error handling, etc. yet] that does that, and uses VLA Properties instead of (subst)/(entmod) with entity data [lightly tested]:

(vl-load-com); if needed
(defun C:TCYC (/ textss tobj); = Text [or Mtext] Content = its Y Coordinate
  (if (setq textss (ssget ":L" '((0 . "*TEXT"))))
    (repeat (setq n (sslength textss)); then
      (setq tobj (vlax-ename->vla-object (ssname textss (setq n (1- n)))))
      (vla-put-TextString
        tobj
        (rtos
          (cadr ; Y coordinate
            (vlax-get tobj
              (if (and (= (vla-get-ObjectName tobj) "AcDbText") (/= (vlax-get tobj 'Alignment) 0))
                ; plain Text other than left-justified?
                'TextAlignmentPoint ; then [= (assoc 11)]
                'InsertionPoint ; else [= (assoc 10)]
              ); if
            ); vlax-get
          ); cadr
        ); rtos
      ); vla-put....
    ); repeat
  ); if
); defun

Awesome, thanks all
