inline AsyncTaskManager *getAsyncTaskManager()
inline RVA getOffset() const
QString cmd(const char *str)

send a command to Rizin

Note

if you want to seek to an address, you should use CutterCore::seek.

Parameters

str – the command you want to execute

Returns

command output

inline QString cmd(const QString &str)
bool asyncCmd(const char *str, QSharedPointer<RizinCmdTask> &task)

send a command to Rizin asynchronously

Note

connect to the &RizinTask::finished signal to add your own logic once the command is finished. Use task->getResult()/getResultJson() for the return value. Once you have setup connections you can start the task with task->startTask() If you want to seek to an address, you should use CutterCore::seek.

Parameters
  • str – the command you want to execute

  • task – a shared pointer that will be returned with the Rizin command task

inline bool asyncCmd(const QString &str, QSharedPointer<RizinCmdTask> &task)
QString cmdRaw(const char *cmd)

Execute a Rizin command cmd. By nature, the API is executing raw commands, and thus ignores multiple commands and overcome command injections.

Parameters

cmd – - a raw command to execute. Passing multiple commands (e.g “px 5; pd 7 && pdf”) will result in them treated as arguments to first command.

Returns

the output of the command

inline QString cmdRaw(const QString &cmd)

a wrapper around cmdRaw(const char *cmd,).

QString cmdRawAt(const char *cmd, RVA address)

Execute a Rizin command cmd at address. The function will preform a silent seek to the address without triggering the seekChanged event nor adding new entries to the seek history. By nature, the API is executing a single command without going through Rizin shell, and thus ignores multiple commands and tries to overcome command injections.

Parameters
  • cmd

    - a raw command to execute. If multiple commands will be passed (e.g “px 5; pd 7

    && pdf”) then only the first command will be executed.

  • address – - an address to which Cutter will temporarily seek.

Returns

the output of the command

inline QString cmdRawAt(const QString &str, RVA address)

a wrapper around cmdRawAt(const char *cmd, RVA address).

void cmdEsil(const char *command)

send a command to Rizin and check for ESIL errors

Note

If you want to seek to an address, you should use CutterCore::seek.

Parameters

command – the command you want to execute

inline void cmdEsil(const QString &command)
bool asyncCmdEsil(const char *command, QSharedPointer<RizinCmdTask> &task)

send a command to Rizin and check for ESIL errors

Note

connect to the &RizinTask::finished signal to add your own logic once the command is finished. Use task->getResult()/getResultJson() for the return value. Once you have setup connections you can start the task with task->startTask() If you want to seek to an address, you should use CutterCore::seek.

Parameters
  • command – the command you want to execute

  • task – a shared pointer that will be returned with the Rizin command task
