cursive-logger-view

A fork of cursive-flexi-logger-view.

This project provides a new debug view for gyscos/cursive using the emabee/flexi_logger crate. This enables the FlexiLoggerView to respect the RUST_LOG environment variable as well as the flexi_logger configuration file. Have a look at the demo below to see how it looks.

How does it look like?

Usage

Simply add dependencies

cargo add log flexi_logger cursive cursive_logger_view

Using the FlexiLoggerView

use cursive::{
    view::Scrollable,
    views::{Dialog, Panel},
};
use cursive_logger_view::{cursive_flexi_logger, FlexiLoggerView};
use flexi_logger::Logger;

fn main() {
    // we need to initialize cursive first, as the cursive-flexi-logger
    // needs a cursive callback sink to notify cursive about screen refreshs
    // when a new log message arrives
    let mut siv = cursive::default();

    Logger::try_with_env_or_str("debug")
        .expect("Could not create Logger from environment :(")
        .log_to_file_and_writer(
            flexi_logger::FileSpec::default()
                .directory("logs")
                .suppress_timestamp(),
            cursive_flexi_logger(&siv),
        )
        .duplicate_to_stderr(flexi_logger::Duplicate::Warn)
        .append()
        .format(flexi_logger::colored_with_thread)
        .format_for_files(flexi_logger::detailed_format)
        .format_for_stderr(flexi_logger::colored_default_format)
        .print_message()
        .start()
        .expect("failed to initialize logger!");

    siv.add_layer(Panel::new(FlexiLoggerView::scrollable()));
    // omit `scrollable` to remove scrollbars
    // siv.add_layer(DebugView::new());

    siv.add_layer(Dialog::text("hello world").scrollable());
    log::info!("info, test log message");
    log::error!("dbg, hello world");
    log::warn!("warn, hello world");

    siv.run();
}
