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 CutterCore::getInstance()
.
Calling a radare2 command
There are two ways to do it:
CutterCore::cmd()
(Discouraged) Only use it for commands which yells no outputCutterCore::cmdj()
To be used with json commands likecmdj("agj")
orcmdj("aflj")
. It is way easier to parse a json output.
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");
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
Code formatting
We follow these guidelines to format the code. If in doubt, you can use AStyle 2.06 to format the code. The command line for formatting the code according to the style is:
astyle --style=kr --indent=spaces=4 --align-pointer=name --align-reference=name --convert-tabs --attach-namespaces --max-code-length=100 --max-instatement-indent=120 --pad-header --pad-oper filename.cpp
Functions documentation
It's good to add some documentation to your functions when needed. To do so we follow these rules.
