Is it possible to filter warnings?

[cool-RR]

We've had 2 discussions where I disagreed that things should be warnings. Is there a way for me in my .visidatarc file to say "A message that matches this regex should not be a warning but a regular message"? Or even censor messages completely when they match that regex.

Alas, no, I can't think of an easy way to do this without modifying the status code. That said, one or maybe both of the warnings could be reworded and/or downgraded to plain status messages, which would maybe take away some large part of the annoyance for you?

Rewording won't help me much, downgrading would. But then again, I'm likely to be annoyed by an endless stream of warnings in the future. Maybe I'll just monkeypatch vd.status in my .visidatarc.

I made such a solution now by monkeypatching:

STATUS_PATTERNS_BY_FORCED_PRIORITY = {
    -1: ( # Priority of `-1` means to drop the message completely
        re.compile(r'^sampling [0-9]+ rows$'), 
    ),
    0: (
        re.compile(r'guessed "dir" filetype based on contents'), 
    ),
}

# Monkeypatching `vd.status` to filter some messages to a lower priority:

@VisiData.api
def status(vd: VisiData, *args, priority: int = 0) -> bool:
    'Display *args* on status until next action.'
    if not args:
        return True

    ### Forcing different priority on some messages: ###############################################
    #                                                                                              #
    messages = tuple(map(str, args))
    for message in messages:
        for forced_priority, patterns in STATUS_PATTERNS_BY_FORCED_PRIORITY.items():
            for pattern in patterns:
                if pattern.match(message):
                    priority = min(priority, forced_priority)
                    
    if priority < 0:
        return False
    
    k = (priority, messages)    
    #                                                                                              #
    ### Finished forcing different priority on some messages. ######################################
    
    vd.statuses[k] = vd.statuses.get(k, 0) + 1

    source = visidata.statusbar.getStatusSource()

    if not vd.cursesEnabled:
        msg = '\r' + visidata.statusbar.composeStatus(args)
        if vd.options.debug:
            msg += f' [{source}]'
        builtins.print(msg, file=sys.stderr)

    return vd.addToStatusHistory(*args, priority=priority, source=source)

I like it! Your .visidatarc is getting pretty epic =)
