Commands Added

Reading & Writing

  • /hexParse <code string> [rename]: parse input code into supported held item; optional rename argument to rename the item.
  • /hexParse read: read handheld item's iota, parse into code and show in chat window; the result will be copied
    when clicked.
  • /hexParse read_signatures: same as read, but ignores all known pattern IDs and outputs all as angle signatures.
  • /hexParse clipboard [rename]: read client clipboard text and parse into supported held item; optional rename argument to rename
    the item.
  • /hexParse clipboard_angles [rename]: same as clipboard, but only accept patterns input with raw angle string like
    "wedsaq".
  • /hexParse clipboard_hexpattern [rename]: (experimental) same as clipboard, but accepts .hexpattern format; warning: only partial features supported.
  • /hexParse share: (experimental) same as read but broadcasts iota's raw content and click-copy-able parsed code to
    every player in the server.
  • /hexParse read_hexbug: same as read but translates the result to the format used by discord HexBug's /patterns hex command. note:
    non-pattern constants and some old registry names still need to be handled manually
  • /hexParse mind_stack ...: read/write iota from player's mind (staff casting VM)
    • ... peek: read the last iota inside mind stack; gets null if stack is empty
    • ... push <code>: parse code and push into mind stack
    • ... push_clipboard: same as above, but code comes from clipboard
  • /hexParse property ...: (Hexcellular interop) get/set data for PropertyIota; used property names all force-added leading _ for security reason
    • ... read <propName>: read and parse from certain property
    • ... write <propName> <code>: write code into certain property
    • ... clipboard <propName>: same as above, but code comes from clipboard

Configs

  • /hexParse (macro/dialect) ...: edit client-saved code dialects (1-on-1 mapping, not starting with #) and macros (
    mapped to code segments, starting with #)
    • ... list: list all saved macros/dialects; there exist several predefined macros from the nature
    • ... define <key> <value>: define a macro/dialect mapping; could be fresh-new or overriding existed one.
    • macro define_clipboard <key>: same as above, but only for macros, and reads player's clipboard
    • ... remove <key>: remove mapping entry with given key (if exists)
  • /hexParse conflict: conflict resolver for multiple patterns with same short name (ID path)
    • only enables in physical client (singleplayer, local multiplayer) or with OP permission
    • ... or ... list: list all short names pointed by multiple long IDs
    • ... list <short_name>: list all conflicting IDs under certain short name
    • ... set <short_name> <long_ID>: redirect certain short name to input pattern ID

Misc. & Helpers

  • /hexParse donate [amount]: donate custom amount of media to the nature. Pay if you feel guilty using this mod ::)
  • /hexParse learn_great: Read handheld items and learns great pattern(s) inside.
  • /hexParse lehmer [...nums]: calculate lehmer code for given permutation (from ascending, e.g. 0 1 2 3 4); input
    should be separated with space; the result number can be used for Swindler's Gambit.

OP-Only Commands

  • /hexParse unlock_great (unlockAll|lockAll|unlock <pattern id>|lock <pattern id>): controls great pattern unlocking
    process of current
    world by locking/unlocking all at once, or a single great pattern each execution.

Patterns Added

  • comment_switcher: Transforms input Comment Iota into String Iota, or everything else into Comment Iota.
  • code2focus: Equivalent to /hexParse clipboard (now not only focuses).
  • focus2code: Equivalent to /hexParse read.
  • remove_comments: Clears comment iotas from a (nested) list input.
  • learn_patterns: Read handheld items and learns great pattern(s) inside.
  • create_linebreak: Adds a line-break comment iota with space-indents of given number to the stack.
  • donate: Equivalent to /hexParse donate.
  • (great spell) compile: takes in a MoreIotas string iota, and parses it into a code list.

Introduction also written in HexParse Patterns section inside the book.

Misc. Features

  • At each pattern's page, press Shift to display the pattern's registry ID

New Iota: CommentIota

CommentIota displays string inside, and parses into a null iota (with id: "hexparse:comment") which executes doing
nothing.
Comment iotas includes text comments, line-breaks & indents, and unknown great spell placeholders.
When player holds Shift key, all comments will be hidden.

Frequently Asked Questions

HexParse server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is HexParse compatible with fabric and forge and neoforge?

HexParse officially supports fabric, forge, neoforge for Minecraft 1.21.1, 1.20.1, 1.19.2. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with HexParse – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if HexParse consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
