Custom logging level

[konqueror1]

I am using flexy_logger for simultaneously log to file and stdout. I try using that macro:

macro_rules! bold_red {
($($arg:tt)) => (
log::log!(log::Level::Info, "{}",
format_args!("\x1b[1;31m{}\x1b[0m", format_args!($($arg)))
);
)
}

Stdout works perfect but when writing to file ANSI escape codes are in the file. I can strip codes with regex as workaround but I am sure there is more idiomatic way to do it.

Yes, you can achieve what you need with something like this:

use flexi_logger::{Duplicate, FileSpec, Logger};
use log::{debug, error, info, trace, warn};

fn main() {
    let _logger = Logger::try_with_env_or_str("info")
        .unwrap()
        .log_to_file(FileSpec::default())
        .duplicate_to_stdout(Duplicate::All)
        .start()
        .unwrap();

    error!("Test error");
    warn!("Test warning");
    info!("Test info");
    debug!("Test debug");
    trace!("Test trace");
}

The program prints to stdout in colors and writes to the file without color escape codes.
