![]() We can do a decent job splitting on just a few symbols:įor atom in atoms : if not atom or atom = ' ' : continue elif atom = 'C' and atoms in : result. By looking at premade opcode lists or disassembling every instruction ourselves, we can see that there aren’t that many patterns. What we’ll do is parse the string into one of several classes of formats. PossibleAddressToken: Integers that are likely addressesĮndMemoryOperandToken: The end of a memory operand TextToken: Text that doesn’t fit into the other tokens ![]() OperandSeparatorToken: The comma or whatever else separates tokens InstructionToken: The instruction mnemonic Here’s how we would split the LD HL,($C234): token Addresses could be followed when double clicked. ![]() All registers could be highlighted when clicked. If the disassembly text were broken into types, Binja could do some cool tricks. See checkpoint #4 for the architecture code, and drop in skwrapper.py alongside in the plugins directory so it can disassemble. Now actual Z80 assembly is being returned. get_instruction_text ( b ' \x2a\x34\xbc\x1a ', 0 ) (, 3 ) Checkpoint #4 Create a hello.py in your plugin directory (you can also quickly open that folder using the Tools menu in Binary Ninja itself): My First Pluginįirst, let’s verify we can get a very simple plugin running. In the second part of the series, I’ll introduce more of the concepts behind Binary Ninja’s IL and how that forms the basis for its advanced analysis. ![]() This first post in the series is meant to get you going with a very fast architecture disassembler in an afternoon by leveraging an existing disassembler and wrapping it into the appropriate APIs. Specifically, this series of blog posts will get you started from zero plugin writing experience to a fully functional architecture with easy to verify checkpoints along the way in a short amount of time. ![]() While we’ve published example architectures before, this blog post is meant to serve as a more detailed introduction to what goes into adding an architecture. Binary Ninja is built to be as extensible as possible and that includes adding and extending new architectures. ![]()
