I'm writing a plugin for IDA PRO with IDAPython and I need to make a dump of the full disassembled code with offsets.

I know I can export a html file and then parse it but I cannot call the GenerateFile function with the GENFLG_GENHTML flag from the script since that function only works from the gui

idc.GenerateFile(OFILE_LST, idc.GetInputFile()+'.html', 0, idc.BADADDR, GENFLG_GENHTML)

(when I run the plugin it gives me unhandled exception but if I write the same instruction from the IDA command line it works).

I can extract the .asm file but it is not useful to me because it does not contain the offsets. Are there any solutions?

  • Do you need an HTML, or just offsets and the ASM?

  • Also, what versions of IDA and IDAPython are you using?

  • @tmr232 I need the full disassembly with the offsets, the output format is not important as long i can parse it. I'm using IDA 6.6

You're currently passing a string as the second argument to GenerateFile(), but the second argument needs to be a file handle.

  • But that same function called from IDA command line works perfecly...

  • That sounds like a nice feature offered by the GUI. However, to use the function from a script you should follow the correct calling convention. Jan 8, 2016 at 15:15
  • So what shoud I do? Create/open a file f = open("file.html", "w") and then use f in GenerateFile?

  • Use fopen(). Jan 8, 2016 at 15:32

    Great, looks like you can use Python's open() function then. Jan 8, 2016 at 15:59
