SPDLOG_LEVEL is currently supported to control log levels via load_env_levels. This patch adds support for other environment variable names, such as MYAPP_LEVEL, for load_env_levels.

// Init levels and patterns from env variables SPDLOG_LEVEL

// Inspired from Rust's "env_logger" crate (https://crates.io/crates/env_logger).
|
|
// Note - fallback to "info" level on unrecognized levels
|

|
|
// Examples:
|
|
//
|
|
// set global level to debug:
|
|
// export SPDLOG_LEVEL=debug
|
|
//
|
|
// turn off all logging except for logger1:
|
|
// export SPDLOG_LEVEL="*=off,logger1=debug"
|
|
//
|
|
|
|
// turn off all logging except for logger1 and logger2:
|
|
// export SPDLOG_LEVEL="off,logger1=debug,logger2=info"
