ASCIICHAT_INSTALL_PREFIX

#define ASCIICHAT_INSTALL_PREFIX   "/usr"

CONFIG_DEBUG

#define CONFIG_DEBUG	(		fmt,
			...
	)

Value:

  do {                                                                                                                 \
    /* Debug messages are only shown in debug builds after logging is initialized */                                   \
    /* Use log_debug which safely checks initialization itself */                                                      \
    log_debug(fmt, ##__VA_ARGS__);                                                                                     \
  } while (0)

Print configuration debug message.

Debug messages use the logging system if it's initialized, otherwise they are silently dropped.

CONFIG_WARN

#define CONFIG_WARN	(		fmt,
			...
	)

Value:

  do {                                                                                                                 \
    (void)fprintf(stderr, "WARNING: Config file: " fmt "\n", ##__VA_ARGS__);                                           \
    (void)fflush(stderr);                                                                                              \
  } while (0)

Print configuration warning to stderr.

Config warnings are printed directly to stderr because logging may not be initialized yet when configuration is loaded. This ensures users see validation errors immediately.
