Lonelog

A Standard Notation for Solo RPG Session Logging

v1.5.0

A lightweight shorthand language designed to separate mechanics from fiction, stay compact at the table, and scale seamlessly from quick one-shots to sprawling campaigns.

The five core Lonelog symbols: @ ? d: -> =>
session-log.md
### S1 Dark alley, midnight
@  Sneak past the guard
d: Stealth 4 vs TN 5 -> Fail
=> I kick a bottle. Guard turns!
?  Does he see me clearly?
   -> No, but…
=> He's suspicious, starts walking toward the noise
@

Format-agnostic

Works identically in digital Markdown code blocks or analog paper notebooks.

d:

Toolbox, not a rulebook

Fully modular. Use the five core symbols or layer in Clocks, Threads, and NPC tags as needed.

Built for scannability

Standardised tokens let external tools, plugins, and human readers parse logs at a glance.
