Weidu REPLACE_TEXTUALLY Scripting Question?

  You don't need to use COPY_EXISTING_REGEXP for just a single script.. This will work:

  COPY_EXISTING ~AR0125.BCS~  ~override~
    DECOMPILE_AND_PATCH BEGIN
      REPLACE_TEXTUALLY  ~bd_tazok_dead","AR0125~  ~TazokDead","GLOBAL~
    END
  BUT_ONLY
  

  
  
  REPLACE_TEXTUALLY's pretty simple like that. You can also use special characters, for example, this will also work:

  REPLACE_TEXTUALLY   ~bd_taz.+0125~  ~TazokDead","GLOBAL~
  

  Just make sure you're not replacing lines you don't want to replace, if you do use special characters.

  If the strings you're trying to use in REPLACE_TEXTUALLY have any special characters in them, you need to escape them or otherwise set up a regexp for them.
  
  So, for your example with those " characters in the string? Those need to be escaped, because otherwise they would delimit the string. Both of the samples Dan_P provided would throw syntax errors.
  
  So, correcting that first one ...

  COPY_EXISTING ~AR0125.BCS~  ~override~
    DECOMPILE_AND_PATCH BEGIN
      REPLACE_TEXTUALLY  ~bd_tazok_dead\",\"AR0125~  ~TazokDead\",\"GLOBAL~
    END
  BUT_ONLY
  

  Well, I think only the quotes need to be escaped...

  @jmerry , this is kind of awkward but, what I posted works.
  
  Quotes aren't special characters for weidu. Now, if there were square brackets, those would need to be escaped, and only for the text that's being replaced. Special characters aren't used for the new text. I think the fixed example you have would actually fail to install because of the backslash after the comma in the new text.
  
  
  Edit: GraionDilach corrected one part of this. Quotes are special characters, but they don't need to be escaped when inside tildes. Also, I meant that regexp isn't used in the new text, not "special characters" in general.

  Quotes(") are special characters in WeiDU and can be used for variable definition as tildes (~) can. The reason tildes are more common is because one doesn't need to escape the inner quotes that way. Similarly, WeiDU also allows to use five tildes(~~~~~) for variable definition to provide an option where one doesn't need to escape the inner tildes.

  @GraionDilach , TIL then, thanks for the explanation. I was just going by the weidu readme, which doesn't include quotes in the special characters section (I'm not an expert with this stuff by any means). Edit: meant regular expressions section, not "special characters".
  
  Regardless, the method in my original reply works since, like you said, the quotes don't need to be escaped if inside tildes.

  Good to know. That's not an interaction I'd ever considered before.
