Logger Module
A simple logging system that provides structured logging with search capabilities.
Logs are stored in hourly files with a consistent format that makes them both human-readable and machine-parseable.
Features
- Structured logging with categories and error types
- Automatic timestamp management
- Multi-line message support
- Search functionality with filtering options
- Human-readable log format
Usage
import freeflowuniverse.herolib.core.logger
import freeflowuniverse.herolib.data.ourtime
// Create a new logger
mut l := logger.new(path: '/var/logs')!
// Log a message
l.log(
cat: 'system',
log: 'System started successfully',
logtype: .stdout
)!
// Log an error
l.log(
cat: 'system',
log: 'Failed to connect\nRetrying in 5 seconds...',
logtype: .error
)!
// Search logs
results := l.search(
timestamp_from: ourtime.now().warp("-24h"), // Last 24 hours
cat: 'system', // Filter by category
log: 'failed', // Search in message content
logtype: .error, // Only error messages
maxitems: 100 // Limit results
)!
Log Format
$time
$cat - $msg
$cat - first line of message
second line of message
third line ...
E $cat - first line of message
E second line of message
E third line ...
- time is expressed in '1980-07-11 21:23:42' == time_to_test.format_ss()
- if cat has '-' inside it will be converted to '_'
- $cat max 10 chars, and always takes the 10 chars so that the logs are nicely formatted
- the first char is ' ' or 'E' , E means its the logtype error
