majiayu000 Event Log
JSONL-based event logging for external program integration. Events mirror database event creation and enable hooks similar to Claude Code's event system.
Purpose
- Emit structured events for external consumers
- Enable hook-based integrations
- Mirror the database event stream
Log Location
- Default:
.ikigai/logs/current.log - Override:
$IKIGAI_LOG_DIR/current.log
APIs
DI-Based (Preferred)
#include "logger.h"
// Create logger with explicit context
ik_logger_t *logger = ik_logger_create(ctx, working_dir);
// Create and emit event
yyjson_mut_doc *doc = ik_log_create();
yyjson_mut_val *root = yyjson_mut_doc_get_root(doc);
yyjson_mut_obj_add_str(doc, root, "event", "chunk_received");
yyjson_mut_obj_add_int(doc, root, "bytes", len);
ik_logger_debug_json(logger, doc); // Takes ownership, frees doc
Legacy Global (Migration)
// Initialize once
ik_log_init(working_dir);
// Emit events
yyjson_mut_doc *doc = ik_log_create();
// ... populate doc ...
ik_log_debug_json(doc); // Takes ownership
// Shutdown
ik_log_shutdown();
