peek-core 1.0.0

//! General config file support: `~/.config/peek/config.toml` (or XDG_CONFIG_HOME/peek/config.toml).
//!
//! Used by peek-cli for default flags and peekd socket path, and by peekd for socket path.
//! Env vars (e.g. PEEK_PEEKD_SOCKET) override config file values.
//!
//! Example `config.toml`:
//!
//! ```toml
//! [defaults]
//! no-color = false
//! resolve = true
//!
//! [peekd]
//! socket-path = "/run/peekd/peekd.sock"
//!
//! [export]
//! default-format = "md"
//! ```
