A terminal-based TUI application for managing tabletop RPG campaigns, inspired by lazygit/lazydocker. Supports three game systems (four rule variants) in a unified interface.

dnd5e and dnd5.5e share the same catalog data and browsing UI; each shows only the monsters/items/spells/classes/races/feats appropriate to its ruleset (2024 core-book revisions replace their 2014 counterpart by name; content never revised for 2024 still shows up in both). Adventures, sourcebooks and backgrounds are shared/unfiltered across both.

go build -o lazyrpg .                          # All systems
go build -tags dnd5e -o lazyrpg-dnd5e .        # D&D 5e (2014) only
go build -tags dnd55e -o lazyrpg-dnd55e .      # D&D 5.5e (2024) only
go build -tags swade -o lazyrpg-swade .        # Savage Worlds only
go build -tags daggerheart -o lazyrpg-dh .    # Daggerheart only

Single-system builds are smaller and skip the system selector on startup.

lazyrpg                          # System selector (skipped if only one system compiled in)
lazyrpg --system dnd5e           # Launch D&D 5e (2014 rules) directly
lazyrpg --system dnd5.5e         # Launch D&D 5e (2024 rules) directly
lazyrpg --system swade           # Launch Savage Worlds directly
lazyrpg --system daggerheart     # Launch Daggerheart directly
lazyrpg --version                # Show version

The application remembers the last used system and highlights it in the selector.

After picking a system, a progress line (bar, current loading step, elapsed time) is printed while its data files load — D&D 5e in particular embeds several large YAML files and can take a few seconds.

• Saves: ~/.lazyrpg/<system>/ for each system (dnd5e and dnd5.5e save separately)
• Last system: ~/.lazyrpg/state.yml
• Config data: embedded in the binary (YAML)

All three systems share the same dice expression engine. Expressions are entered in the Dice panel (a to add, e to edit).

Roll several different expressions in one command (results stored separately):

d6,d8             → rolls d6 and d8 independently
d6,d8,1d20+4      → three separate rolls

Repeat the same expression N times:

1d6 x3            → three independent d6 rolls
1d20+5 x4         → four d20+5 rolls

Roll a check; if it passes, also roll the second expression:

d20 > 15 2d6+1    → if d20 > 15, then roll 2d6+1

1d20+5 > 10 x3    → three independent pass/fail checks

Annotate damage types within a single expression:

(4d8+1:slash)+(3d6:acid)
(1d6:cold)+(2d4:poison)

In the detail panel, press Enter on any line containing a dice expression (e.g. 2d6+3) to roll it instantly.

Available as two systems, dnd5e (2014 rules) and dnd5.5e (2024 rules) — same UI and panels, catalog content filtered per ruleset as described above.

• Dice — Roll dice expressions, save/load roll history
• Encounters — Track HP, initiative, conditions, death saves for monsters and characters
• Catalog — Browse monsters, items, spells, characters, races, feats, books, adventures, random generators, notes
• Description / Treasure — Full text detail and treasure generation

• Add monsters from the catalog or create custom entries
• Track current/max HP with temporary HP support (temp is consumed before regular HP)
• Toggle HP mode between average value and dice formula (Space)
• Roll initiative per entry or all at once; sort by initiative (S); activate turn mode (*)
• Advance turns with n; re-sort or reset at any time
• Death saves: when a character reaches 0 HP, a 💀 appears. Press R to roll 1d20:
  • Natural 1 → 2 failures
  • 2–9 → 1 failure
  • 10–19 → 1 success
  • Natural 20 → critical: 3 successes, HP becomes 1
  • 3 failures → ☠️ (dead)
  • 3 successes → stabilized (skull removed, HP stays 0)
• Add/remove conditions ([ / ] adjust duration in rounds); condition badges use emoji symbols
• Yank/paste entries (y/p); undo/redo (u/r)
• Generate an encounter from the party composition (g)
• XP Budget: when the Encounter panel is focused, the panel title and detail header show adjusted XP and difficulty (Easy/Medium/Hard/Deadly) computed from custom characters in the encounter

Accessible from the Random catalog panel:

• Name lists (w): generate N fantasy names with [ ]/[x] checkboxes; press Space on a name list entry to toggle used/unused; state is persisted
