Documentation

env_logger is a de facto standard Rust logger implementation, which allows controlling logging to stderr via the RUST_LOG environment variable.

This is a fork of env_logger that makes it work as a slog-rs drain.

Notable changes:

• Support for slog-stdlog to provide support for legacy info!(...) like statements.
• envlogger does not do any formatting anymore: slog-envlogger can be composed with any other slog-rs drains, so there's no point for it to provide it's own formatting. You can now output to a file, use JSON, have color output or any other future that slog ecosystem provides, controlling it via RUST_LOG environment var.

Warning: Documentation has been been left mostly untouched, which means some places of it might be confusing.

See examples directory.

The simplest way to convert existing project to use slog-rs+slog-envlogger is shown in simple example

For more proper (and powerful) version see proper example

Using slog-stdlog scopes you can make parts of the code log additional information (see scopes example):
