### [`v0.11.0`](https://togithub.com/rust-cli/env_logger/blob/HEAD/CHANGELOG.md#0110---2024-01-19)
[Compare Source](https://togithub.com/rust-cli/env_logger/compare/v0.10.2...v0.11.0)
##### 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](https://docs.rs/anstyle) is a minimal, runtime string styling API and is re-exported as `env_logger::fmt::style`
- [owo-colors](https://docs.rs/owo-colors) is a feature rich runtime string styling API
- [color-print](https://docs.rs/color-print) for feature-rich compile-time styling API
[custom_format.rs](https://docs.rs/env_logger/latest/src/custom_format/custom_format.rs.html)
uses `anstyle` via
[`Formatter::default_level_style`](https://docs.rs/env_logger/latest/env_logger/fmt/struct.Formatter.html#method.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`
##### Compatibility
MSRV changed to 1.71
##### Features
- Automatically adapt ANSI escape codes in logged messages to the current terminal's capabilities
- Add support for `NO_COLOR` and `CLICOLOR_FORCE`, see https://bixense.com/clicolors/
##### Fixes

- [Support capturing for cargo test](https://togithub.com/sebasmagri/env_logger/pull/127)
### 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:
```rust
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`](https://togithub.com/rust-cli/env_logger/releases/tag/v0.6.0): 0.6.0
[Compare Source](https://togithub.com/rust-cli/env_logger/compare/v0.5.13...v0.6.0)
### 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`.

- [Don't clobber a previously set level filter](https://togithub.com/sebasmagri/env_logger/pull/117)
### 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.

### More Details
#### `Formatter::default_level_style`
The style used in the default format for printing level names can be fetched using the new `default_level_style` method on a `Formatter`. The below example will format just the record message using the style of its level:
```rust
builder.format(|buf, record| {
let level_style = buf.default_level_style(level);
write!(buf, "{} ", level_style.value(record.args()))
});

- [@KodrAus](https://togithub.com/KodrAus) [add some docs on defaulting env vars](https://togithub.com/sebasmagri/env_logger/pull/96)
### More Details
#### `Builder::default_format_timestamp_nanos`
The `Builder::default_format_timestamp_nanos` method can be used to toggle the precision of timestamps in the default format. When set to `true`, timestamps will include a 6-digit nanosecond component like `2018-02-14T00:28:07.000000000Z`.
#### `Formatter::precise_timestamp`
Custom formats can get a precise timestamp instead of the default by calling the `precise_timestamp` method instead of the existing `timestamp` one.

### More Details
#### `filter_module` and `filter_level`
Adds two new methods to `Builder` and `filter::Builder` that are specific cases of the existing `filter` method:
- `filter_module` adds a directive for the given module. It's the same as `filter(Some(module), level)`
- `filter_level` adds a directive for all modules. It's the same as `filter(None, level)`
### [`v0.5.8`](https://togithub.com/rust-cli/env_logger/releases/tag/v0.5.8): 0.5.8

### Contributions
- [@KodrAus](https://togithub.com/KodrAus) [Add support for default env values](https://togithub.com/sebasmagri/env_logger/pull/81)
### More Details
#### `Env::filter_or` and `Env::write_style_or`
Default values for environment variables can be specified on the `Env` type using the `filter_or` and `write_style_or` methods. The default value is a string in the same format as the environment variable:
```rust
impl Env {
fn filter_or(self, filter_env: E, default: V) -> Self
where
E: Into>,
V: Into>;
fn write_style_or(self, write_style_env: E, default: V) -> Self
where
E: Into>,
V: Into>;
}
```
In usage:
```rust
let env = Env::default()
.filter_or("MY_LOG_LEVEL", "trace")
.write_style_or("MY_LOG_STYLE", "always");
env_logger::init_from_env(env);
```
#### `DEFAULT_FILTER_ENV` and `DEFAULT_WRITE_STYLE_ENV`
Two new constants are publicly exported that correspond to the default environment variable names used for the filters and style preferences.

### Key Changes
- Wrap the `termcolor::Color` API so it's no longer a public dependency
### Contributions
- [@KodrAus](https://togithub.com/KodrAus) [Wrap termcolor's color api](https://togithub.com/sebasmagri/env_logger/pull/75)
### More Details
This patch fixes an issue that slipped through `0.5.0` where the `termcolor::Color` type was re-exported instead of redefined.
**This is a potentially breaking change**
Instead of re-exporting `termcolor::Color`, we now redefine the same API in `env_logger`. The potential breakage is if anyone was relying on the fact that `env_logger::Color` and `termcolor::Color` were equivalent types. This was only obvious from the source, and a survey of public code using `env_logger` and call for comment hasn't revealed any code relying on this.
### [`v0.5.5`](https://togithub.com/rust-cli/env_logger/releases/tag/v0.5.5): 0.5.5
[Compare Source](https://togithub.com/rust-cli/env_logger/compare/v0.5.4...v0.5.5)
### Key Changes
- Allow toggling parts of the default format without having to write one from scratch
### Contributions
- [@KodrAus](https://togithub.com/KodrAus) [Allow toggling parts of the default format](https://togithub.com/sebasmagri/env_logger/pull/66)
### More Details
#### `Builder::default_format_*`
The default format can be easily tweaked by conditionally enabling/disabling parts of it in the main `Builder`. The API looks like:
```rust
impl Builder {
fn default_format(&mut self) -> &mut Self;
fn default_format_timestamp(&mut self, write: bool) -> &mut Self;
fn default_format_module_path(&mut self, write: bool) -> &mut Self;
fn default_format_level(&mut self, write: bool) -> &mut Self;
}
```
Calling `default_format_*` will store whether or not we want to include those parts of the log, without affecting a custom format. That means:
```rust
Builder::new()
.format(|buf, record| { ... })
.default_format_timestamp(false)
.init();
```
Is the same as:
```rust
Builder::new()
.format(|buf, record| { ... })
.init();
```
Setting a custom format won't clobber any values passed to `default_format_*` methods. That means:
```rust
Builder::new()
.default_format_timestamp(false)
.format(|buf, record| { ... })
.default_format()
.init();
```
Is the same as:
```rust
Builder::new()
.default_format_timestamp(false)
.init();
```
#### `Builder::from_default_env`
A new `from_default_env` method that's a convenient way of calling `from_env(env_logger::Env::default())`.

**NOTE:** These release notes are collected from the `0.5.0-rc.1` and `0.5.0-rc.2` release notes.
### Key Changes
- Support for using custom environment variables to parse the log level filter and color output
- Added colors with configuration through an environment variable and an RFC3339-formatted timestamp to the default format
- Buffer log output so logs over multiple lines won't end up interleaved in multi-threaded applications
- Move the filter parsing into its own module so it's easier to consume in custom loggers
- Documentation!
### Breaking Changes
- `LogTarget` has been renamed to `Target`
- `LogBuilder` has been renamed to `Builder`
- The `Builder::format` method now accepts a `F: Fn(&mut Formatter, &Record) -> Result<()> + Sync + Send`. This is the new formatting API that writes into a `Formatter` instead of producing an owned `String`
- `Builder::init` will panic if the logger can't be initialised. A new `Builder::try_init` method has been added with the same semantics as the old `Builder::init` method
### New Dependencies
- [`chrono`](https://crates.io/crates/chrono) for the timestamp
- [`termcolor`](https://crates.io/crates/termcolor) for record buffering and colors

Thanks to everybody who helped make this release of `env_logger` happen!
### More Details
#### Disabling colors
Adds a new builder property for whether or not to include colors. By default this is controlled by the `RUST_LOG_STYLE` environment variable, but it can be overridden.
Setting this environment variable to `never` will disable colors and other styles:
```shell
$ export RUST_LOG_STYLE=never
$ ./my-app
```
Valid values are:
- `auto` (or missing/invalid) will decide whether or not the terminal supports colors
- `always` will always use colors
- `never` will never use colors
In order to support multiple environment variables, I've refactored our `from_env` functions to accept a generic `T: Into`, where `Env` is a container for the environment variables we care about. These methods can now be called in a few ways:
```rust
// reads filters from `MY_LOG` and styles from `RUST_LOG_STYLE`
env_logger::init_from_env("MY_LOG");
// reads filters from `MY_LOG` and styles from `MY_LOG_STYLE`
env_logger::init_from_env(Env::default().filter("MY_LOG").write_style("MY_LOG_STYLE"));
```
This lets us add new environment variables in the future without potentially breaking people. But it does mean if you're overriding all environment variables that new ones could slip in without you noticing.
#### Using alternative environment variables
Since we use two environment variables to configure the logger we need an ergonomic way to pass different combinations of those variables to `from_env` methods. This PR adds an `Env` type with builder methods for naming environment variables:
```rust
env_logger::init_from_env(Env::new().filter("MY_LOG"));
```
With a few `From` conversions, the above is also equivalent to:
```rust
env_logger::init_from_env("MY_LOG");
```
Whether or not we want to keep these conversions is up for discussion.
#### Writing colors
The color API has been refactored and made public so you can use them in your own formats:
```rust
let mut style = buf.style();
style.set_color(Color::Red).set_bold(true).set_bg(Color::White);
writeln!(buf, "{}", style.value(42))
```
This saves you from having to split the writes into multiple calls and juggle `Result` types.
#### Writing timestamps
Call the `timestamp` method on a `Formatter` to get an opaque timestamp that can be logged. It'll be written in an RFC3339 format:
```rust
let ts = buf.timestamp();
writeline!(buf, "log at: {}", ts)
```

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](https://togithub.com/hcpl) [Test with `-Z minimal-versions` on CI](https://togithub.com/sebasmagri/env_logger/pull/114) - [@afck](https://togithub.com/afck) [Add missing RFC3339 URL to fix rustdoc](https://togithub.com/sebasmagri/env_logger/pull/105) - [Make all dependencies optional](https://togithub.com/sebasmagri/env_logger/pull/100) - [Rework the default format](https://togithub.com/sebasmagri/env_logger/pull/82) - [Don't clobber a previously set level filter](https://togithub.com/sebasmagri/env_logger/pull/117) ### 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. ### [`v0.5.13`](https://togithub.com/rust-cli/env_logger/releases/tag/v0.5.13): 0.5.13 [Compare Source](https://togithub.com/rust-cli/env_logger/compare/v0.5.12...v0.5.13) ### Key Changes - Add a public function for getting the default level style ### Contributions - [@felixrabe](https://togithub.com/felixrabe) [Typo](https://togithub.com/sebasmagri/env_logger/pull/98) - [@upsuper](https://togithub.com/upsuper) [Move default level style to a public function](https://togithub.com/sebasmagri/env_logger/pull/99) - [@Eh2406](https://togithub.com/Eh2406) [update some debs for minimal-versions](https://togithub.com/sebasmagri/env_logger/pull/101) ### More Details #### `Formatter::default_level_style` The style used in the default format for printing level names can be fetched using the new `default_level_style` method on a `Formatter`.

When set to `true`, timestamps will include a 6-digit nanosecond component like `2018-02-14T00:28:07.000000000Z`. #### `Formatter::precise_timestamp` Custom formats can get a precise timestamp instead of the default by calling the `precise_timestamp` method instead of the existing `timestamp` one. ### [`v0.5.11`](https://togithub.com/rust-cli/env_logger/releases/tag/v0.5.11): 0.5.11 [Compare Source](https://togithub.com/rust-cli/env_logger/compare/v0.5.10...v0.5.11) ### Key Changes - Update `termcolor` to `1.0` - Bump minimum `rustc` to `1.20.0` ### Changes to minimum Rust The minimum version of Rust required has been set at `1.20.0`.
