Function global_config_dir

atomic-config/src/lib.rs:421–423

Get the global configuration directory. Resolution order: 1. The `ATOMIC_CONFIG_DIR` environment variable, if set — used verbatim as the config directory (the one containing `config.toml`). This lets tests isolate the global config on every platform, and lets users relocate it. 2. `dirs::home_dir()/.atomic` (the default). The variable is read at call time so it can be set and restored per test (
