How can I parse a 2da file and replace text?

[RoyalProtector]

I'm trying to find, unsuccessfully, a way of fixing a mistake in a 2DA file with WeiDu. It's a bug that was introduced in recent versions of BGEE/BG2EE in CLSWPBON.2DA. I need to find a row for a particular class and change the penalty for a proficiency into another.

It would be easy to just replace the file entirely or do it with a programming language that I know by treating it as a text file, but I'd rather go for a non destructive solution.

Thanks

WeiDU provides several commands for manipulating tables.

This code example searches for the "SHADOWDANCER" line and changes the last column to another value.

COPY_EXISTING ~clswpbon.2da~ ~override~
  // Reads whole table into memory to speed up operation
  READ_2DA_ENTRIES_NOW clswpbon 1
  // Actual data starts at row 3
  FOR (row = 3; row < clswpbon; ++row) BEGIN
    // Reads class/kit label from column 0 for each row
    READ_2DA_ENTRY_FORMER clswpbon row 0 label
    // Match found?
    PATCH_IF (~%label%~ STR_EQ ~SHADOWDANCER~) BEGIN
      // Sets column 3 ("ZERO_SKILL_THAC0") to value 3
      // Note: It's important to put updated values into a different variable!
      SET_2DA_ENTRY_LATER clswpbon_out row 3 3
      // No need to continue the FOR-loop
      SET row = clswpbon
    END
  END
  // Write changes back to file
  SET_2DA_ENTRIES_NOW clswpbon_out 1
BUT_ONLY

Thanks, that's really helpful. Looks like you already knew what I wanted to change
