Debug Log

Printf-style logging for development and debugging. Compiles away completely in release builds.

Purpose

Development-time visibility into program state
Add arbitrary trace points during debugging
Zero overhead in release builds

Usage

#include "debug_log.h"

DEBUG_LOG("value=%d state=%s", x, state_name);
DEBUG_LOG("=== Entering function ===");
DEBUG_LOG("buffer contents: %.*s", (int)len, buf);

Build Configuration

Build	DEBUG defined	Behavior
Debug	Yes	Writes to `IKIGAI_DEBUG.LOG`
Release	No	Compiles to `((void)0)` - removed entirely

Initialization

In debug builds, call once early in

main()

#ifdef DEBUG
ik_debug_log_init();
#endif

Or simply use the macro form (safe in any build):

ik_debug_log_init();  // No-op if DEBUG not defined

Output Format

[2025-01-15 10:30:00] src/client.c:34:main: === Session starting, PID=12345 ===

Format:

[timestamp] file:line:function: message

Log Location

File:
```
IKIGAI_DEBUG.LOG
```
in working directory
Truncated on each run (via
```
ik_debug_log_init
```
)

Inspecting Logs

tail -f IKIGAI_DEBUG.LOG

Alternate Buffer Note

ikigai runs in terminal alternate buffer mode.

printf()

and

fprintf(stderr, ...)

are not visible during execution. Use

DEBUG_LOG

instead.
