| // This file defines macros used to control the behavior of pw_log statements. |
| // Files that use pw_log may define these macros BEFORE any headers are |
| // #included to customize pw_log. |
| // |
| // For example, the following sets the log module name to "Foobar" and the |
| // minimum log level to WARN: |
| // |
| // #define PW_LOG_MODULE_NAME "Foobar" |
| // #define PW_LOG_LEVEL PW_LOG_LEVEL_WARN |
| // |
| // #include "foo/bar.h" |
| // #include "pw_log/log.h" |
| // |
| // Users of pw_log should not include this header directly; include |
| // "pw_log/log.h" instead. This header is separate from "pw_log/log.h" to avoid |
| // circular dependencies when implementing the pw_log facade. |
| #pragma once |
| |
| #include "pw_log/config.h" |
| |
| // These configuration options differ from the options in pw_log/config.h in |
| // that these should be set at a module/compile unit level rather than a global |
| // level level. |
| |
| // Default: Module name |
| // |
| // An empty string is used for the module name if it is not set. The |
| // PW_LOG_MODULE_NAME_DEFINED macro is set to 1 or 0 to allow pw_log backends to |
| // behave differently if the module name is defined. For example, a backend |
| // might prefix the format string with PW_LOG_MODULE_NAME ": ", but only if the |
| // module name is provided. |
| #ifdef PW_LOG_MODULE_NAME |
| #define PW_LOG_MODULE_NAME_DEFINED 1 |
| #else |
| #define PW_LOG_MODULE_NAME "" |
| #define PW_LOG_MODULE_NAME_DEFINED 0 |
| #endif // PW_LOG_MODULE_NAME |
| |
| // Default: Log level filtering |
| // |
| // All log statements have a level, and this define sets the log level to the |
| // globally set default if PW_LOG_LEVEL was not already set by the module. |
| // This is compile-time filtering if the level is a constant. |
| #ifndef PW_LOG_LEVEL |
| #define PW_LOG_LEVEL PW_LOG_LEVEL_DEFAULT |
| #endif // PW_LOG_LEVEL |
| |
| // Default: Flags |
| // |
| // For log statements like LOG_INFO that don't have an explicit argument, this |
| // is used for the flags value. |
| #ifndef PW_LOG_FLAGS |
| #define PW_LOG_FLAGS PW_LOG_FLAGS_DEFAULT |
| #endif // PW_LOG_FLAGS |
| |
| // DEPRECATED: Use PW_LOG_FLAGS. |
| // TODO(pwbug/561): Remove this macro after migration. |
| #ifndef PW_LOG_DEFAULT_FLAGS |
| #define PW_LOG_DEFAULT_FLAGS PW_LOG_FLAGS |
| #endif // PW_LOG_DEFAULT_FLAGS |
| |
| // Default: Log enabled expression |
| // |
| // This expression determines whether or not the statement is enabled and |
| // should be passed to the backend. |
| #ifndef PW_LOG_ENABLE_IF |
| #define PW_LOG_ENABLE_IF(level, flags) PW_LOG_ENABLE_IF_DEFAULT(level, flags) |
