============
|
|
|
|
This page shows some hints about the coding conventions.
|
|
|
|
*Disclaimer: It is a work in progress and we will provide soon a fully
|
|
documented API.*
|
|
|
|
Coding advices
|
|
--------------
|
|
|
|
CutterCore class
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
This is the main class where every link with r2 is made. It is *unique*
|
|
accross the whole process. To access it, simply call ``Core()``.
|
|
|
|
Example:
|
|
|
|
.. code:: cpp
|
|
|
|
Core()->getOffset();
|
|
|
|
Calling a radare2 command
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
There are two ways to do it: \* ``CutterCore::cmd()`` *(Discouraged)*
|
|
Only use it for commands which yells no output \* ``CutterCore::cmdj()``
|
|
To be used with json commands like ``cmdj("agj")`` or ``cmdj("aflj")``.
|
|
It is way easier to parse a json output.
|
|
|
|
Example:
|
|
|
|
.. code:: cpp
|
|
|
|
QJsonArray array = Core()->cmdj("pdj 1 @ main").array();
|
|
|
|
Seek the current file
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
To modify radare2 seek use ``CutterCore::seek(const RVA offset)``. This
|
|
is important because it will emit a
|
|
``CutterCore::seekChanged(RVA offset)`` signal. Never ever call
|
|
``cmd("s offset")``;
|
|
|
|
Example:
|
|
|
|
.. code:: cpp
|
|
|
|
Core()->seek(0x00C0FFEE);
|
|
|
|
Creating a widget
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
Make sure to connect the ``CutterCore::seekChanged(RVA offset)`` signal
|
|
so your widget refreshes its output when radare2 seek is modified
|
|
(switching to another function, etc.).

General coding guidelines
|
|
-------------------------
|
|
|
|
Coding style
|
|
~~~~~~~~~~~~
|
|
|
|
We follow `these guidelines <https://wiki.qt.io/Qt_Coding_Style>`__ to
|
|
format the code. If in doubt, you can use `AStyle
|
|
2.06 <https://sourceforge.net/projects/astyle/files/astyle/astyle%202.06/>`__
|
|
to format the code. The command line for formatting the code according
|
|
to the style is:
|
|
|
|
.. code:: bash
|
|
|
|
astyle --project=src/Cutter.astylerc src/filename.cpp
|
|
|
|
Loops
|
|
^^^^^
|
|
|
|
We use C++11 foreach loop style which means any “foreach” loop should
|
|
look like:
|
|
|
|
.. code:: cpp
|
|
|
|
for (QJsonValue value : importsArray) {
|
|
doSomething(value);
|
|
}
|
|
|
|
Nullptr
|
|
^^^^^^^
|
|
|
|
Please do not use ``0`` nor ``Q_NULLPTR``, only use ``nullptr``.
|
|
|
|
Example:
|
|
|
|
.. code:: cpp
|
|
|
|
QObject *object = nullptr;
|
|
|
|
Connecting signals
|
|
^^^^^^^^^^^^^^^^^^
|
|
|
|
To connect a signal to a slot, this is the preferred way to do it:
|
|
|
|
.. code:: cpp
|
|
|
|
connect(sender, &QObject::destroyed, this, &MyObject::objectDestroyed);
|
|
|
|
The main reason is that this syntax allows the use of lambda functions.
