Traversing functions in IDA

IDA General

hi

I was wondering if these tasks could be assigned with hotkeys:

  • copy a named func’s address
  • go to address by name e.g: myfunc+0x42
  • go to address by module offset; like in x64dbg “:$+0x1234”

Hi @alex ,
So, to summarize:

  • go to address by name: This is already supported out of the box through the Jump Anywhere dialog (Jump → Jump Anywhere), which can be invoked with the G hotkey
  • go to address by module offset: Jump Anywhere can also evaluate expressions - see Expression-Language Identifiers (although this is probably not the most convenient solution).
  • Regarding the first query: If you mean copying a function name to the clipboard, we currently don’t have the built-in action for this, but it can be implemented as an IDAPython script. Here’s an example:
import ida_idaapi
import ida_funcs
import ida_name
import ida_ida
import ida_kernwin

from PySide6 import QtWidgets

ACTION_HOTKEY = "Ctrl-Shift-Q"


def copy_current_function_name():
    ea = ida_kernwin.get_screen_ea()
    if ea == ida_idaapi.BADADDR:
        ida_kernwin.warning("No current address")
        return

    func = ida_funcs.get_func(ea)
    if func is None:
        ida_kernwin.warning(f"No function at {ea:#x}")
        return

    name = ida_funcs.get_func_name(func.start_ea)
    if not name:
        name = ida_name.get_ea_name(func.start_ea)

    # In case you want to keep the mangled name, remove this
    demangled = ida_name.demangle_name(
        name, ida_ida.inf_get_short_demnames())
    if demangled:
        name = demangled

    QtWidgets.QApplication.clipboard().setText(name)
    ida_kernwin.msg(f"Copied function name to clipboard: {name}\n")


class copy_func_name_plugin_t(ida_idaapi.plugin_t):
    flags = ida_idaapi.PLUGIN_KEEP
    comment = "Copy current function's name to clipboard"
    help = "Copies the name of the function at the current EA to the clipboard"
    wanted_name = "Copy function name to clipboard"
    wanted_hotkey = ACTION_HOTKEY

    def init(self):
        return ida_idaapi.PLUGIN_KEEP

    def run(self, arg):
        copy_current_function_name()

    def term(self):
        pass


def PLUGIN_ENTRY():
    return copy_func_name_plugin_t()
