Bennu console

The Bennu console is a handy debugging tool. Many commands can be entered in it, like process manipulation or variable manipulation. The current state of Globals, Constants, Locals, Publics, Privates can also be monitored. One can add text to it in the programcode by using the function say().

To use the debugger, you need import the debug module (mod_debug) in your source code, run in debug mode by compiling your program in bgdc.exe with the argument "-g", and when you are running your application with the interpreter(bgdi.exe) you can activate it in-program with ALT+C.

List all local variables of the specified process. The process can be specified by either its name or its processID.

PUBLICS <processName|processID>

List all local variables of the specified process. The process can be specified by either its name or its processID.

Debugging Commands

TRACE

Execute the next instruction.

BREAK

List all set breakpoints.

BREAK <processName|processID>

Add a breakpoint on the execution of the specified process. The process can be specified by either its name or its processID.

DELETE

Delete a breakpoint on the execution of the specified process. The process can be specified by either its name or its processID.

CONTINUE

Continue the execution (close the console).

DOFRAME

Execute the next frame.

Misc

SHOW <expression>

Evaluate and show the specified expression.

Process Management

See signals for further explanation about the following signaling commands.

RUN <processName> [<argument>]

Start a process with optional arguments.

KILL <processName|processID>

Kill the specified process. The process can be specified by either its name or its processID.

WAKEUP <processName|processID>

Wake up the specified process. The process can be specified by either its name or its processID.

SLEEP <processName|processID>

Put the specified process to sleep. The process can be specified by either its name or its processID.

FREEZE <processName|processID>

Freeze the specified process. The process can be specified by either its name or its processID.

KILLALL <processName|processID>

If a processname is specified, kill all processes with that name; if a processID is specified, only kill that process.

WAKEUPALL <processName|processID>

If a processname is specified, wake up all processes with that name; if a processID is specified, only wake up that process.

SLEEPALL <processName|processID>

If a processname is specified, put all processes with that name to sleep; if a processID is specified, only put that process to sleep.

FREEZEALL <processName|processID>

If a processname is specified, freeze all processes with that name; if a processID is specified, only freeze that process.

Expressions

You can evaluate free expressions and see/alter the values of variables.

<variable> [= <value>]

Return or alter a global variable.

<processName|processID>.<variable> [= <value>]

If a processID is specified, the value of the local, private or public variable of that process is returned or altered. If a processName is specified, the process with that name and the lowest ID is assumed.

Example

Process Main()
Begin
    Repeat
        frame;
    Until(key(_ESC))
End
