IDAPython - Python plugin for Interactive Disassembler
------------------------------------------------------
What is IDAPython?
------------------
IDAPython is an IDA plugin which makes it possible to write scripts
for IDA in the Python programming language. IDAPython provides full
access to both the IDA API and any installed Python module.
Check the scripts in the examples directory to get an quick glimpse.

Installation from binaries
--------------------------
1. Install 2.6 or 2.7 from http://www.python.org/
2. Copy the whole "python" directory to %IDADIR%
3. Copy the contents of the "plugins" directory to the %IDADIR%\plugins\
4. Copy "python.cfg" to %IDADIR%\cfg
Usage
-----
 - Run script: File / Script file (Alt-F7)
 - Execute Python statement(s) (Ctrl-F3)
 - Run previously executed script again: View / Recent Scripts (Alt+F9)
* Batch mode execution:
Start IDA with the following command line options:
 -A -OIDAPython:yourscript.py file_to_work_on
or
-Syourscript.py
or
-S"yourscript.py arg1 arg2 arg3"
(Please see http://www.hexblog.com/?p=128)
If you want fully unattended execution mode, make sure your script
exits with a qexit() call.
By default scripts run after the database is opened. Extended option
format is:
 -OIDAPython:[N;]script.py
Where N can be:
 0: run script after opening database (default)
 1: run script when UI is ready
 2: run script immediately on plugin load (shortly after IDA starts and before processor modules and loaders)
* User init file
You can place your custom settings to a file called 'idapythonrc.py'
that should be placed to
${HOME}/.idapro/
or
%AppData%\Hex-Rays\IDA Pro
The user init file is read and executed at the end of the init process.
Please note that IDAPython can be configured with "python.cfg" file.
* Invoking Python from IDC
The IDAPython plugin exposes a new IDC function "RunPythonStatement(string idc_code)" that allows execution
of Python code from IDC
* Invoking IDC from Python
It is possible to use the idc.Eval() to evaluate IDC expressions from Python
* Making Python the default language
By default, IDA will use IDC to evaluate expressions. It is possible to change the default language to use
Python instead of IDC.
In order to do that, please use the following IDC code:
RunPlugin("python", 3)
To disable Python language and revert back to IDC:
RunPlugin("python", 4)
