cmon2lib

Personal Python library for convenient personalized functionality.

Logging

cmon2lib provides a unified logging system with cross-language compatibility (Python and Bash).

Dual-Output Logging

cmon2lib logs to both console (terminal) and file simultaneously:

Console Colors:

• INFO: No color (clean output)
• DEBUG/TRACE: Dim gray
• SUCCESS: Green
• WARNING: Yellow + WARN: prefix
• ERROR: Red + ERR: prefix

File Format Example:

2026-04-12 18:14:00 | INFO    | ctaiga:get_authenticated_user:33 | simon | Authenticated user ID: 123

Console Output Example (same message):

Authenticated user ID: 123

For WARNING:

WARN: something went wrong

For ERROR:

ERR: connection failed

Python Usage (clog)

from cmon2lib import clog

# Basic logging
clog('info', 'message')
clog('debug', 'value: {}', 42)

# With exception
try:
    raise ValueError("test error")
except ValueError as e:
    clog('error', 'Operation failed', exception=e)
# Output: Operation failed: ValueError: test error

# Log levels: trace, debug, info, success, warning, error, critical
clog('warning', 'Something might be wrong')
clog('success', 'Operation completed')

Python Usage (cprint - Rich UI Output)

from cmon2lib import cprint

# Rich console output - no file logging
# Supports Rich markup tags for colors and formatting
cprint('info', '[green]✓[/green] Item synced successfully')
cprint('info', '[cyan]Source:[/cyan] {}", source_name)
cprint('warning', '[yellow]![/yellow] Something may be wrong')
cprint('error', '[red]✗[/red] Operation failed')

# cprint is for UI output (trees, tables, formatted messages)
# clog is for operational logs (process info, errors, warnings)

### Bash Usage

```bash
source cmon_lib/cmon_logging.sh
init_clog "my_script"

clog_info "message"
clog_error "error message"
clog_warn "warning message"
clog_success "success message"

Log Levels

File Logging

Logs are automatically written to _clog/ directory next to the module:

• Archive log: {timestamp}_{module}.log - all log messages
• Summary log: {module}_csummary.log - INFO, SUCCESS, ERROR only

If WARN or ERROR is logged, the archive is renamed to *_WARN.log or *_ERR.log.

Log Cleanup

Archive logs older than 30 days are automatically deleted on initialization.

Protected files (never deleted automatically):

• *_WARN.log - renamed warning archives
• *_ERR.log - renamed error archives
• *_csummary.log - summary logs

Features

• Auto-init on first clog() call (Python)
• Executing user tracking (via USER or USERNAME env vars)
• Single-line exception formatting
• Age-based cleanup (30 days for archives)
• No external dependencies (uses loguru for Python)
