    Provides methods for accessing and modifying the contents of DBPF formatted files.

    Provides methods for accessing and modifying the contents of DBPF formatted files. Currently, only DBPF version 1.0 is supported (used by SimCity 4).

    DBPF files are accessed via DbpfFiles, a container of DbpfEntries. The content of a DbpfEntry can be accessed from BufferedEntries in decoded form as DbpfType, such as Exemplar, Fsh or Sc4Path.

    This package object provides additional type aliases for DbpfExceptions.

    Examples

    To get started, it is easiest to start the REPL via sbt console, which loads all the dependencies and useful initial import statements. Reading a DBPF file, sorting its entries by TGI and writing back to the same file could be achieved like this:

    val dbpf = DbpfFile.read(new File("foobar.dat"))
    dbpf.write(dbpf.entries.sortBy(_.tgi))

    This example shifts the GIDs of all LTexts by +3:

    dbpf.write(dbpf.entries.map { e =>
      if (e.tgi matches Tgi.LText)
        e.copy(e.tgi.copy(gid = e.tgi.gid + 3))
      else
        e
    })

    Another example: This decodes all the Sc4Path entries and rotates them by 90 degree.

    val writeList = for (e <- dbpf.entries) yield {
      if (e.tgi matches Tgi.Sc4Path) {
        val be = e.toBufferedEntry.convertContentTo(Sc4Path)
        be.copy(content = be.content * RotFlip.R1F0)
      } else {
        e
      }
    }
    dbpf.write(writeList)

    The following example finds the first entry that is an exemplar and contains a property with a specific ID. (Note the view to avoid unnecessary decoding if the exemplar is already among the first entries.)

    val id = UInt(0x12345678)
    dbpf.entries.view.
      filter(_.tgi matches Tgi.Exemplar).
      map(_.toBufferedEntry.convertContentTo(Exemplar)).
      find(_.content.properties.contains(id))
