IDAPython comes in two flavors:
* IDAPython-for-Python2
* IDAPython-for-Python3
* IDAPython-for-Python2.7
* IDAPython-for-Python3.x
# Switching between Python 2 and Python 3.
# Switching between IDAPython-for-Python2.7, and IDAPython-for-Python3.x.
Depending on your choice at the install time, your "plugins" directory will have
one version of plugin installed as idapython.[dll|so|dylib] (and/or idapython64) and
the other will be present with the ".disabled" extension. To switch, just rename the
current version to .disabled and the disabled one back to the .dll/.so/.dylib
(depending on your OS)
IDA ships with two versions of IDAPython:
* one that runs using the Python2.7 runtime
* one that runs using the Python3.x runtime
For example, to swith from Python 3 to Python 2 on Windows:
By default, IDA will load the one that runs using the Python3.x runtime.
In order to have IDA use IDAPython-on-Python2.7, the file
'use_python2' needs to be present in the 'python' subdirectory.
1. rename idapython.dll to idapython.3.disabled and idapython64.dll to idapython64.3.disabled
2. rename idapython2.disabled to idapython.dll and idapython642.disabled to idapython64.dll
That file will be looked for in the following places:
* IDA's install path: path/to/ida_install/python/use_python2
* The 'IDAUSR' directory:
+ ~/.idapro/python/use_python2 (on Linux/OSX)
+ %APPDATA%\Hex-Rays\IDA Pro\python\use_python2 (on Windows)
+ [...or any other directory if the environment variable $IDAUSR is set]
# Selecting which Python3.x install runtime to use
# Selecting a Python install to use
The situation for IDAPython-for-Python2 is simple: it uses Python 2.7,
and will expect that [lib]python2.7.[dll|so|dylib] is present in the system
The situation for IDAPython-for-Python2.7 is simple: it uses Python 2.7,
and will expect that [lib]python2.7.[dll|so|dylib] is present in the system
library path so that IDA can find it.
When it comes to IDAPython-for-Python3, it gets more complex: because
different users might have different (and possibly multiple) versions
of Python3 installed, IDA comes with a tool called `idapyswitch`, that
can be run to select the desired Python3 runtime to tailor
IDAPython-for-Python3 to.
But when it comes to IDAPython-for-Python3.x, things gets more complex:
because different users might have different (and possibly multiple)
versions of Python3.x installed, IDA comes with a tool called `idapyswitch`
that can be run to select the desired Python3.x runtime.
If you selected IDAPython-for-Python3 at installation-time,
`idapyswitch` utility should already have been run, and selected
the most appropriate Python3 version.
If you selected IDAPython-for-Python3.x at the installation time,
the `idapyswitch` utility should already have been run and selected
the most appropriate Python3.x version.
Should you want to switch to another Python3 install after installation,
please run `idapyswitch` from IDA's directory. It will scan for Python
installs present in the system's standard locations and offer you to choose one.
Should you want to switch to another Python3.x install after installation,
please run `idapyswitch` from the IDA directory. It will scan for Python
installs present in the system's standard locations and offer you to choose one.
It also supports optional command-line switches to handle non-standard installs.
Run `idapyswitch -h` to see them.
On Windows, you may need to run it as administrator
so it can patch sip.pyd (library required for PyQt bindings).
