Supported IO Item Types

  • Focuses
  • Spell Books
  • (1.20) Thought Knots
  • recognized by item classes (matched through the item class hierarchy), able to add more via HexParseAPI or IOMethod

Commands Added

Reading & Writing

  • `/hexParse [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 `: 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 `: read and parse from certain property
    • `... write `: write code into certain property
    • `... clipboard `: 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 `: define a macro/dialect mapping; could be fresh-new or overriding existed one.
    • `macro define_clipboard `: same as above, but only for macros, and reads player's clipboard
    • `... remove `: 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 |lock )`: controls great pattern unlocking process of current world by locking/unlocking all at once, or a single great pattern each execution.

Patterns Added

  • switch_comment: Transforms input Comment Iota into String Iota, or everything else into Comment Iota; has no effect without MoreIotas.
  • 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; has no effect without MoreIotas.

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.
