PyGhidra open_program loader options

[bdemick]

Is there a way to pass loader arguments like BASE_ADDRESS from pyghidra.open_program? I see that the loader class can be specified, but no ability to pass an option list.

No, you'd have to use the AutoImporter java class. It looks like open_program() uses the GhidraProject java class, which in turn uses AutoImporter, but there is not currently a way to pass in the loader arguments this way. I am in the process of rethinking this whole API, so I will take this into consideration.

In case anyone stumbles across this down the road, here's how I'm handling it with the AutoImporter (roughly):

HeadlessPyGhidraLauncher().start()
from ghidra.app.util.importer import MessageLog, AutoImporter
from ghidra.app.util.opinion import BinaryLoader, Loader
from ghidra.base.project import GhidraProject
from ghidra.program.model.lang import LanguageID
from ghidra.program.util import DefaultLanguageService
from ghidra.util.task import TaskMonitor
from generic.stl import Pair
from java.io import File
from java.lang import Object
from java.lang import String
from java.util import ArrayList
import jpype

arch = "PowerPC:BE:32:default"
baseaddr = 0x20000
msg_log = MessageLog()
monitor = TaskMonitor.DUMMY
lid = LanguageID(arch)
language_service = DefaultLanguageService.getLanguageService()
language = language_service.getLanguage(lid)
spec = language.getDefaultCompilerSpec()
consumer = Object()
proj = GhidraProject.createProject(tmploc, file.name, True)
baseaddr_opt = ArrayList([Pair(String(Loader.COMMAND_LINE_ARG_PREFIX + "-baseAddr"), String(f"{baseaddr:#0x}"))])

load_results = AutoImporter.importByUsingSpecificLoaderClassAndLcs(
    File(str(file)),
    proj.getProject(),
    String(proj.getRootFolder().getPathname()),
    BinaryLoader,
    baseaddr_opt,
    language,
    spec,
    consumer,
    msg_log,
    monitor
)
program = load_results.getPrimaryDomainObject()
# Do stuff with the program

Is it possible to just change the base address after the binary is imported? something like program.getMemory().setbaseaddress ?

wait.. i now see
