# Developing IDAPython: best practices
|
|
|
|
### Rule of thumb
|
|
|
|
If you are doing something non-trivial in IDAPython, or if you added something
|
|
to the C++ SDK which will then be reflected in IDAPython, an *immensely*
|
|
useful rule-of-thumb is to perform a diff of the autogenerated SWiG wrappers.
|
|
|
|
Typically:
|
|
`cp -R obj/x64_linux_gcc_32/wrappers/ /tmp/wrappers-before`
|
|
<recompile...>
|
|
`git diff /tmp/wrappers-before/ obj/x64_linux_gcc_32/wrappers/`
|
|
|
|
It is always useful to make sure that SWiG did the right thing -- *especially*
|
|
when modifying typemaps, but not only.
|
|
|
|
### How to add new module?
|
|
|
|
We use the "zzz" placeholder for a module name in this "how-to".
|
|
|
|
1. create file swig/zzz.i
|
|
```
|
|
%{
|
|
#include <zzz.hpp>
|
|
%}
|
|
%include "zzz.hpp"
|
|
```
|
|
|
|
2. add zzz to the `MODULES_NAMES` var in makefile
|
|
|
|
3. add a line to python/idc.py if you want to autoload this module
|
|
```
|
|
import ida_zzz
|
|
```
|
|
|
|
4. build
|
|
|
|
5. update the content of api_contents.txt
|
|
(from obj/.../api_contents.txt.new)
|
|
|
|
6. rebuild
|
|
|
|
7. update the content of pydoc_injections.txt
|
|
(from obj/.../pydoc_injections.txt)
