# Contributing to Cutter
|
|
|
|
There are many ways you can contribute to cutter.
|
|
The easy one is to open issues with bugs you found on the application.
|
|
The second one is to fix issues found in the GitHub issues tracker.
|
|
|
|
## Opening an issue
|
|
|
|
Make a clear description of the bug/feature, use screenshots, send binaries, etc.
|
|
|
|
## Contributing to the code
|
|
|
|
Note that cutter is still under development and many parts of the code are to be improved.
|
|
|
|
### 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:
|
|
```c++
|
|
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:
|
|
```c++
|
|
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:
|
|
```c++
|
|
Core()->seek(0xdeadbeef);
|
|
```
|
|
|
|
### 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:
|
|
|
|
```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:
|
|
```c++
|
|
for (QJsonValue value : importsArray) {
|
|
doSomething(value);
|
|
}
|
|
```
|
|
|
|
#### Nullptr
|
|
|
|
Please do not use `0` nor `Q_NULLPTR`, only use `nullptr`.
|
|
|
|
Example:
|
|
```c++
|
|
QObject *object = nullptr;
|
|
```
|
|
|
|
#### Connecting signals
|
|
|
|
To connect a signal to a slot, this is the preferred way to do it:
|
|
```c++
|
|
connect(sender, &QObject::destroyed, this, &MyObject::objectDestroyed);
|
|
```
|
|
The main reason is that this syntax allows the use of lambda functions.
|
|
|
|
### Functions documentation
|
|
|
|
It's good to add some documentation to your functions when needed. To do so we follow these [rules](http://doc.qt.io/qt-5/qdoc-guide-writing.html).
