HOCON Playground

Browser-side editor for AbstractMenus menu configs. No server, no install. Edit, validate, share.

Two modes

Editor - paste your menu.conf, see parse errors with line:col, view the resolved JSON after substitutions, share a deep-link with another author for a second pair of eyes.
Tutorial - short lessons on HOCON syntax. Each lesson has a goal, progressive hints, and a check that fires as you type. Progress is saved in your browser.

HOCON syntax highlighting (comments, keys, strings, substitutions, durations, includes)
Live parse + diagnostics with squiggles in the editor and a list of errors on the right
Resolved JSON view after ${var} substitutions and override merges
Scope-aware autocomplete - inside actions {} it suggests action types, inside rules {} it suggests rules, etc.
Enum value completion for material: and sound: (~150 popular Bukkit materials, ~80 sounds)
Hover docs on known keys
10 starter snippets for common blocks (menu, item, clickaction, ...)
Format command (Cmd+Shift+F / Ctrl+Shift+F)
Shareable URL via #config=... (deflate + base64-url)
LocalStorage history (last 5 versions)
Light / dark themes

No semantic schema validation yet (only HOCON syntax + warnings for unknown substitutions)
No inventory preview - the playground does not render the resulting Minecraft menu
include directives produce a warning and are otherwise ignored (no virtual filesystem)
Material / sound autocomplete is a curated subset, not the full Bukkit enums
