Cabler — logs cleanly and simply

Motivations

• The fundamental to-files logging
• The common contenders: info, warning, error. And then: heading for notable events in the program flow, debug for separately toggleable detailed tracing and die for instant suicide with a logged message
• As small as possible, no excess cruft wanted
• But no good features missed either
• Tags error outputs with unique ID's for exact cross referencing
• Timstamped entries, no date-part
  • Cabler is intentionally designed for daily rotated logging — the date is part of the file-structure identification
  • Avoids redundant noise in log
  • Analysis spanning multiple days is an elaborate task. Assumed to be done through tooling / scripting
    • full date timestamp rows should be reconstructed then
• Prefix-tagged outputs identifies different parts of the system in logging
• Errors are output both on stdout and stderr, except when streams go to TTY
• Browser-sympathetic, to avoid troubles in cross-libs
• Colors are used when output to TTY
  • prefix gets a deterministic color based on the text, using hi-color, which may be rendered as the closest ANSI-color if the terminal doesn't support hi-color / 256c.

Examples

Will get to that... Check the test meanwhile.
