Bulk rename functions in IDA Pro

Question

I have a list of tenthousands of {Address} - {Function Name} pairs I dumped with a tool I wrote. Now I want to rename all functions so for example sub_123456 becomes "FooBar", because the list says so.

Any way to do that?

Thanks.

Answer 1

In such cases i would load the list in Vim, change the list to have two columns, the first the addresses, the second the desired names. Like this:

123456 FooBar
124584 BarFoo

Then do :%s/^\(\w\+\)\s\+\(\w\+\)/MakeName(0x\1, "\2");, ending up with a list like this:

MakeName(0x123456, "FooBar");
MakeName(0x124584, "BarFoo");

Then copy the entire Vim buffer to the clipboard with 1G and "*yG. Then in IDA type Shift-F2 to open the manual script editor, and paste using Cmd-V or Ctrl-V.
