Feature request: Function to call if sweep dies #71

Open Deadmansshoe opened 2 years ago

Deadmansshoe commented 2 years ago

Hi everyone,

I had an idea for a new feature, which could enhance Lab-Measurement. Instead of leaving everything as it was before the code crashes (if e.g. a limit is reached or an instrument is no longer reachable), code could be executed. This could give the opportunity to set crucial inputs back to safe values or send a notification to the user.

I thought this could be a function given to the sweep start function call, similar to the function reference given to sweep initialization. 

...
my $crashfunction = sub {
    $yokogawa->set_voltage(value => '0.0');
};

...

$sweep->start(
    measurement => $meas,
    datafile    => $datafile,
    coderef_crash => $crashfunction,
);

What are your ideas to something like that? Do you think this could be possible?

Greetings Robin

Uh, only just saw this. Possible, but most likely not very reliable for nontrivial things... let's talk.
