Imported many binaries with wrong dsPIC language. How to fix quickly?

[gtackett]

I accidentally imported a boat load (thousands) of binaries with the wrong dsPIC33x selected.

These binaries are arranged correctly into 3 different folders, one for each flavor of dsPIC33.

I just need a quick way to set all the binaries in one folder to one selected architecture.

I could script this, but I'm not very clear on how to handle prompting for the new architecture. Once I have that, I already know how to script applying it to all the binaries in a folder..

Maybe someone else here can help?

GhidraScript has an askLanguage method. This will provide the prompt for the new architecture.

You could use LanguageTranslatorFactory to get a translator from the languages if needed. There would need to be a *.trans file though.

Jython should automatically choose the correct method depending on the type.

>>> currentProgram.setLanguage(askLanguage('Choose','OK'),currentProgram.getCompiler(),False,monitor)
Traceback (most recent call last):
  File "python", line 1, in <module>
TypeError: setLanguage(): 1st arg can't be coerced to ghidra.program.model.lang.Language, ghidra.program.util.LanguageTranslator

Should be currentProgram.setLanguage(askLanguage('Choose','OK').getLanguage(),currentProgram.getCompiler(),False,monitor) as askLanguage returns a LanguageCompilerSpecPair

That gives me the same TypeError message.

This can wait until next week, if you're getting bored of it right now. 😄

Faulty error message. It's the second argument that is the problem.

lang = askLanguage('Choose','OK')
id = lang.compilerSpec.compilerSpecID
lang = lang.language
currentProgram.setLanguage(lang, id, False, monitor)

If this results in an IncompatibleLanguageException then you may need to implement the *.trans file or a LanguageTranslatorAdapter.

Also, if you want to do this in a headless script you can hardcode LanguageCompilerSpecPair(String, String)

[gtackett]

It's going to require less hard work to just re-import everything, even though it may take an hour or so to run.

[astrelsky]

That's a shame. There really should be a default for this when translating between variants.
