twyg

A tiny logging setup for Rust applications

I got used to logging my apps in Clojure with Twig and in LFE with Logjam, so here this is.

Usage

I like to put my logging setup in YAML config files for my apps, but however you prefer to do that, you'll need to eventually populate the twyg::LoggerOpts struct:

rust let opts = twyg::LoggerOpts{ colored: true, file: "".to_string(), level: "debug".to_string(), report_caller: true, };

Options:

• colored: setting to false will disable ANIS colors in the logging output
• file: provide a path to a file, and output will be logged there too
• level: case-insensitive logging level
• report_caller: setting to true will output the filename and line number where the logging call was made

With the opts defined, make the setup call:

rust match twyg::setup_logger(&opts) { Ok(_) => {}, Err(error) => { panic!("Could not setup logger: {:?}", error) }, };

All subsequent calls to the standard Rust log functions will use this setup, providing output like the following:

The output in the screenshot above (click for a a full-sized view) is from running the little demo in main.rs.
