(WIP) A lightweight C logging library and parser for event-oriented logs.

Lognestmonster is a general-purpose single-header C logging library that pertains a number of features:

• Nested/layer-based logging capabilities
• Event-oriented log compilation
• Multiple queues or outputs
• Full developer customizability on memory allocation
  • Preprocessor handles to incorporate non-standard memory functions
• Full developer customizability on I/O redirection
  • Generic filesystem log output
  • End-to-end stdout and stdin piping, allowing data transfer over serial, socket, or anything else
• A binary format lighter than plaintext
• A feature-packed but comprehensive standalone deserializer/parser
  • Interactive textual UI (ncurses)
  • Logtree filtering/sorting and navigation
  • Data operations such as binary to plaintext conversions and custom hooks on user-defined events
  • Optional daemon for hook events
  • Full developer customizability on data display, program controls, and hook operations

(WIP) Not yet meant for development or production use

Performance at Different Optimization Levels

Output of ./test performance as of commit b54160c:

Optimization Level	Header Binary Size* (in bytes)	Unit Test Runtime** (in µs)
-O0	22552	70
-O1	18424	67
-O2	22520	69
-O3	26760	68
-Os	18424	69

*Header binary size is measured by compilation of the following source file:

// tests/header_only.c
#define LNM_INIT
#include "lognestmonster.h"

int main(void) {
    return 0;
}

**Median taken from 200 trials run in sequence to account for variable processor conditions and behaviors. Run on a mid-tier 3.3GHz processor (i5-4590). Runtime is measured by the execution and output of the header's unit test.
