Installing:

wget https://raw.githubusercontent.com/LeaoMartelo2/LogNest/main/lognest.h

_{just copy this if you are lazy}

Usage:

(Please refer to the examples if needed)

• Download lognest.h and add it to your project.
• Any specific log level can be disabled with:

#define LOGNEST_DISABLE_<TRACE/WARN/ERROR/DEBUG>

• Change the log type indicator prefix with:

#define LOGNEST_<TRACE/WARN/ERROR/DEBUG>_PREFIX "<custom prefix>"

• The separators ([]) around the type must also be included here.

• Optionally change where the log file is sent to (default: "latest.log") with:

#define LOGNEST_FILE "path/to/log/filename.log"

• Optionally disable the log's time or date of the message with:

#define LOGNEST_DISABLE_TIMESTAMP
/* or */
#define LOGNEST_DISABLE_DATESTAMP

• Optionally allow crashing on error with:

#define LOGNEST_ALLOW_CRASH

(All configuration defines must come before the implementation define)

• For the library to serve as implementation, add: #define LOGNEST_IMPLEMENTATION before finally #include-ing the file.
• Only add the Implementation define to a single file, adding the .h to multiple files is ok.

Latest update changes:

LogNest 2.1.5

• Added LOGNEST_API macro (defaulted to static inline) to allow you to change how lognest functions are defined.

• Added macros do change the prefix of the log level identifier, add this before the implementation define:

#define LOGNEST_<TRACE/WARN/ERROR/DEBUG>_PREFIX "<custom prefix goes here>"

• Added split the macro to divide the timestamp do allow to individually disable the date-stamp with #define LOGNEST_DISABLE_DATESTAMP
• Renamed some internal macros with common names to avoid name hogging.
• Added a option to allow crashing on error:

#define LOGNEST_ALLOW_CRASH
