qlog -- a set of quick logging macros for LibComponentLogging.
qlog is just a small header file which defines a short logging macro for every log level of LibComponentLogging, e.g. qlerror() for error messages and qltrace() for trace messages. Additionally, all logging macros take the current log component from the ql_component preprocessor define which can be (re)defined in your application at a file-level, section-based, or global scope. If you want to include the log component in your logging statements instead of using the ql_component define, you can use the _c variants of the logging macros which take the log component as the first argument, e.g. qlerror_c(lcl_cMain), qltrace_c(lcl_cMain, @"message").
To install qlog, just copy the qlog.h header file to your project and add an import of qlog.h to your prefix header file or to your LibComponentLogging extensions configuration file, e.g.
//
// lcl_config_extensions.h
//
...
#import "qlog.h"
...
Then, define the preprocessor symbol ql_component at a global scope with your default log component, e.g. add a define to your prefix header file:
#define ql_component lcl_cDefaultLogComponent
Now, logging statements can be added to your application by simply using the qlog macros instead of LibComponentLogging's lcl_log macros:
qlinfo(@"initialized");
qlerror(@"file '%@' does not exist", file);
qltrace();
All these logging statements will use the log component from the ql_component define which is visible at the location of the logging statement.
If you want to use a specific log component for all logging statements in a file, you can simply redefine ql_component to match this log component, e.g. by adding a #undef #define sequence at the top of the file, e.g.
#undef ql_component
#define ql_component lcl_cFileLevelComponent
If you want to use a specific log component at a specific location in your code, you can use the _c variants of the macros which take the log component as the first argument, e.g.
qlinfo_c(lcl_cMain, @"initialized");
qlerror_c(lcl_cMain, @"file '%@' does not exist", file);
qltrace_c(lcl_cMain);
