Compatibility with `tauri-plugin-log`

[jeffgardnerdev]

The Tauri log plugin is widely used, but cannot coexist with devtools--this panic error crashes the app on startup when both plugins are added:
error while running tauri application: PluginInitialization("log", "attempted to set a logger after the logging system was already initialized")

This can be worked around by only adding the devtools plugin in development and only adding the log plugin in production, like so:

    let builder = tauri::Builder::default();

    #[cfg(debug_assertions)]
    let builder = builder.plugin(devtools::init());
    
    #[cfg(not(debug_assertions))]
    let builder = builder.plugin(
        tauri_plugin_log::Builder::default()
            # example log plugin config below
            .targets([LogTarget::Stdout, LogTarget::LogDir])
            .with_colors(ColoredLevelConfig::default())
            .level_for("tauri", LevelFilter::Info)
            .level(LevelFilter::Info)
            .build(),
    );
    
    builder
        .plugin(...) # other plugins
        .invoke_handler(tauri::generate_handler![
            ... # handlers
        ])
        ... # other stuff
        .run(tauri::generate_context!())
        .expect("error while running tauri application");

But this doesn't account for any log statements made on the JS side, like this:

import { debug } from 'tauri-plugin-log-api';
debug('debug log entry');

Ideally there would be some way to seamlessly redirect log entries to devtools in development while retaining normal log plugin behavior in production.

Yeah okay so I played around with this somewhat yesterday and I really like your suggestion of making it compatible with the log plugins js functions. However, creating tracing::Metadata objects seems to be a bit tricky :/ will report back when I make further progress

Okay so turns out I was overcomplicating things 😄 and adding compat with tauri-plugin-log meant that I realized a way to make the output of messages generated through log much more useful in general!

I have the same issue as @jeffgardnerdev. There doesn't seem to be a way to configure logs when this is added as a plugin. I have logs everywhere even in production so I get a lot of errors when I do not configure tauri_plugin_log.

Neat tool you have here though.
