do not highlight DEBUG level log messages?

[jtmoon79]

I'm using rich.logging.RichHandler class to highlight a Python logging.Logger, e.g.

import logging
from rich.logging import RichHandler

FORMAT = "%(message)s"
logging.basicConfig(
    level=logging.DEBUG, format=FORMAT, datefmt="[%X]", handlers=[RichHandler()]
)
logger = logging.getLogger("rich")

logger.debug("debug...")
logger.info("info...")
logger.warning("warning...")
logger.error("error...")
logger.fatal("fatal...")

I want DEBUG log level messages to have no highlighting (or maybe even totally dimmed?). This is so it's easier to visually skip past the less important messages.

Is it possible to not highlight (or dim) the DEBUG level log messages using the RichHandler?

I am looking for this as well, I can't get this working. Can someone help please ?

If I check the python -m rich.theme, I am afraid there has to be some hack because it's not possible to change the message per level:

❯ python -m rich.theme
[styles]
...
log.level = none
log.message = none
log.path = dim
log.time = dim cyan
logging.keyword = bold yellow
logging.level.critical = bold reverse red
logging.level.debug = green
logging.level.error = bold red
logging.level.info = blue
logging.level.notset = dim
logging.level.warning = red
...

Changing the log.message will change all log lines.

There is nothing builtin, but you could adapt or extend RichHandler. The code is quite short and straightforward.

Unfortunately it's not so short for me , I am trying to understand the code but it's too complicated for me

I posted a solution to this in #3337

Thanks a lot @sr105 , I will test this 👍🏻

I made the highlighter easier to reuse:

    class StyledHighlighter(Highlighter):
        def __init__(self, *args, style=None, **kwargs) -> None:
            super().__init__(*args, **kwargs)
            assert type(style) is str, f"style must be a string! received {style!r}"
            self.style = style

        def highlight(self, text: Text) -> None:
            text.style = self.style

    def colored_error_filter(record: logging.LogRecord) -> (bool | logging.LogRecord):
        match record.levelno:
            case logging.ERROR:
                record.highlighter = StyledHighlighter(style="bold red")
                return record
            case logging.WARNING:
                record.highlighter = StyledHighlighter(style="bold orange1")
                return record
        return True
