Back to the code request.

What is the string you wish to find?

What is the string you want to replace with?

Find string include "Wild-card characters"

For example:

1.
"300*700"

Code: [Select]
(setq pattern "`*")
(ssget (list (1  (strcat "*" pattern "*")))

replace "*" -> "x"

return: "300x700"

------------------------------
2.
"abc[123]"

Code: [Select]
(setq pattern "[`123`]")
(ssget (list (1  (strcat "*" pattern "*")))

replace "[123]"->"[456]"

return: "abc[456]"

cjw, i'm still not following the description of your question.

To find "300*700" where "*" is the actual "*" character, we can use "300`*700" and apparently you already knew this. Similarly to find "[123]", we can use "`[123`]". I wonder if your question is how to perform the replacement for all the matching instances found.

Instead of giving examples, can you tell us what is the actual problem you're trying to solve?

Code: [Select]
;;CJW-SS-VALUE_LIST By carrot1983
(defun CJW-SS-VALUE_LIST (SS ITEM / I VALUE_LIST)
  (repeat (setq I (sslength SS))
    (setq
      VALUE_LIST
       (cons
(cdr (assoc ITEM (entget (ssname SS (setq I (1- I)))))
)
VALUE_LIST
       )
    )
  )
  VALUE_LIST
)

(defun c:tt ()
  (setq find_pattern "`[123`]")
  (setq replace_pattern "[456]")
  (setq ss (ssget (list (cons 0 "TEXT") (cons 1 "*" find_pattern "*"))))
  (foreach e (CJW-SS-VALUE_LIST ss -1)
    (setq string (cdr (assoc 1 (entget e))))
    (while (vl-string-search find_pattern string);_If find_pattern="`[123`]",always return nil.........
      (setq
string (vl-string-subst replace_pattern find_pattern string);_If find_pattern="`[123`]",always can't work.......
      )
    )
  )

it's some kind of wildcard replacement function
Code: [Select]
(defun wcreplace_sub (Old String)
  (if (wcmatch String Old)
    (1+ (strlen String))
    (wcreplace_sub Old (substr String 1 (1- (strlen String))))
  )
)
(defun wcreplace (New Old String)
  (if (= String "")
    ""
    (if (wcmatch String (strcat Old "*"))
      (strcat New (substr String (wcreplace_sub Old String)))
      (strcat (substr String 1 1)
      (wcreplace New Old (substr String 2))
      )
    )
  )
)
(wcreplace "x" "`*" "300*700")
(wcreplace "[456]" "`[123`]" "abc[123]")
not thoroughly tested though
no support for multiple pattern conditions

Surely so long as this is included any modification is entirely within the intent of the release of the lisp originally?

Thanks for observing and posting that Scott, I missed it completely. <facepalm>
