Migration Guide

env_logger::fmt::Style:
The bespoke styling API, behind color, was removed, in favor of accepting any
ANSI styled string and adapting it to the target stream's capabilities.

Possible styling libraries include:

• anstyle is a minimal, runtime string styling API and is re-exported as env_logger::fmt::style
• owo-colors is a feature rich runtime string styling API
• color-print for feature-rich compile-time styling API

custom_format.rs
uses anstyle via
Formatter::default_level_style

Breaking Change

• Removed bespoke styling API
  • env_logger::fmt::Formatter::style
  • env_logger::fmt::Formatter::default_styled_level
  • env_logger::fmt::Style
  • env_logger::fmt::Color
  • env_logger::fmt::StyledValue
• Removed env_logger::filter in favor of env_filter

Changes to minimum Rust

The minimum version of Rust required has been set at 1.31.0. We may change this in patch versions, but will always flag it in the release notes here.

You can always check the .travis.yml file to see the current minimum supported version.

Contributions

• @​95ulisse Indentation for multiline log messages
• @​oherrala Add more timestamp precisions
• Update to 2018 edition

v0.6.2: 0.6.2

Compare Source

Key Changes

• Additional examples and docs

Contributions

• @​shepmaster Redirect people to GitHub Releases for changesn
• Fix up test init example
• Add some more examples for configuring env_logger
• Fix up the build on nightly compilers

v0.6.1: 0.6.1

Compare Source

Key Changes

• Support better capturing for cargo test
• Don't print internal logs to stdout

Contributions

• @​nlopes Fix path for rust-lang favicon
• @​emilio Don't print to stdout the warnings due to an invalid spec
• Support capturing for cargo test

More Details

Builder::is_test

The is_test method can be used in tests to make sure logs are captured by cargo test the same way println! is:

fn init() {
    let _ = env_logger::builder().is_test(true).try_init();
}

#[test]
fn it_adds_one() {
    init();

    info!("can log from the test too");
    assert_eq!(3, add_one(2));
}

There are performance implications of using is_test though, so it should be avoided outside of unit tests.

v0.6.0: 0.6.0

Compare Source

Key Changes

• Set a policy for changes to the default format
• Make all dependencies besides log optional (but enabled by default)

Breaking Changes

• The default format is not considered stable across patch versions. The best way to get a stable format for later ripgrepping is to define a custom one.
• All dependencies have been made optional except for log. That means compiling env_logger with default-features=false will result in a different experience than in 0.5.x.

Contributions

• @​hcpl Test with -Z minimal-versions on CI
• @​afck Add missing RFC3339 URL to fix rustdoc
• Make all dependencies optional
• Rework the default format
• Don't clobber a previously set level filter

More Details

Disabling dependencies

Using default-features=false will disable all dependencies of env_logger besides log. This will reduce compile times and alter the default format by disabling colours and timestamps.

Disabling default dependencies is the recommended way to use env_logger for libraries that only need it for logging in tests.
