Logging without LogaxLoggerΒΆ
The library can be used to output log without need to setup the LogaxLogger struct, this will require the platform to have output stream or can write to file. If the macro LOGAX_NO_LOGGER is defined before including the logax.h header file, the LogaxLogger struct and all related functions will not be compiled. The following functions provides the API to write to output stream in the supported formats
- logax_write_text_format_to_stream
- logax_write_key_value_format_to_stream
- logax_write_json_format_to_stream
logax_write_text_format_to_stream write the output in plain text format, the first parameter is the stream, followed by the options, the options is the combinations of any of the LOGAXOPTION, LOGAX*LEVEL* and LOGAXFORMATTER* macros.
#include <exotic/logax.h>
int main(int argc, char **argv) {
logax_write_text_format_to_stream(stdout, LOGAX_OPTION_ALL | LOGAX_LEVEL_TRACE, "%s", "Enemy approaching from X=108,Y=877");
}
// output
// 2021-11-21 06:34:07 TRACE crash_test.c:13 Logging the test for TRACE
logax_write_key_value_format_to_stream write the output in a key-value format coloring is ignored in this format, the first parameter is the stream, followed by the options, the options is the combinations of any of the LOGAXOPTION, LOGAX*LEVEL* and LOGAXFORMATTER* macros.
#include <exotic/logax.h>
int main(int argc, char **argv) {
logax_write_key_value_format_to_stream(stdout, LOGAX_OPTION_ALL | LOGAX_LEVEL_TRACE, "%s", "Enemy approaching from X=108,Y=877");
}
// output
// date="2021-11-21" time="06:41:34" level="TRACE" file="crash_test.c" line_number=8 function="main" message="This is a trace output"
logax_write_json_format_to_stream write the output in a json format, the first parameter is the stream, followed by the options, the options is the combinations of any of the LOGAXOPTION, LOGAX*LEVEL* and LOGAXFORMATTER* macros.
#include <exotic/logax.h>
int main(int argc, char **argv) {
logax_write_json_format_to_stream(stdout, LOGAX_OPTION_ALL | LOGAX_LEVEL_TRACE, "%s", "Enemy approaching from X=108,Y=877");
}
// output
// {"date":"2021-11-21","time":"06:42:25","level":"TRACE","file":"crash_test.c","line_number":8,"function":"main","message":"This is a trace output"},
