Script manager for game hackmud, with minification, TypeScript support, and player script type definition generation.

Hackmud Script Manager

Command made for hackmud-environment, which is a scripting environment for hackmud with minification, autocompletes / intellisense, and TypeScript support.

Install with npm install hackmud-script-manager -g to make the hsm command available everywhere.

Features

• Minification
  • This includes auto quine cheating.
    • Supported types are null, numbers, strings, and JSON compatible objects and arrays.
    • Non JSON compatible object keys are quine cheated.
    • Member expressions are converted to index notation so the index string can be quine cheated.
    • And template literals are converted to string concatenation so the strings can be quine cheated.
  • Global variable aliasing.
  • Convert function declarations to arrow function assigned to variable hoisted to the top of the block (function foo() { ... } -> let foo = () => ...).
  • Convert _START and _TIMEOUT to _ST and _TO.
  • Remove unused parameters from the main function expression.
• Modern Javascript Syntax and Features
  • Exponentiation Operator, Object Rest Spread, Optional Catch Binding, JSON strings, Nullish Coalescing Operator, Optional Chaining, Logical Assignment Operators, Numeric Seperators, Class Properties, Class Static Block, Private Property in Object.
  • Bigint literals are converted to BigInt() calls.
  • Hackmud already supports all modern regular expression features.
• Future JavaScript Syntax and Features
  • Warning: TypeScript doesn't support any of these features and these features may change or not actually make it into JavaScript.
  • Decorators, Do Expressions, Function Bind, Function Sent, Partial Application, Pipeline Operator (using the hack proposal and % as the topic token), Throw Expression, Record and Tuple (hash # syntax type).
• TypeScript Support
  • This command/module does not do type checking, it simply removes type annotations so you'll need to rely on your IDE or run tsc seperatly with noEmit.
• And “Cool” Unnecessary Features.
  • Variables declared outside the main function expression automatically become #G global variables.
  • Any code outside the function expression will only run once per top level script execution (#FMCL).
  • Basic seclevel verification.
    • Declaring // @seclevel HIGHSEC or any other seclevel before all of your code stops you from accidentally using #ls. or #ns..
  • Import node_modules modules into your script using import { foo } from "bar" syntax.
  • _SOURCE is replaced with a string of the source code of the script it's in.
  • _BUILD_DATE is replaced with a unix timestamp (Date.now()) of the build date of the script.
  • _SCRIPT_USER is replaced with a string of the user the script was pushed to.
    • This saves characters compared to context.this_script.split(".")[0].
  • _SCRIPT_NAME is like _SCRIPT_USER but for the name of the script.
    • Saves characters compared to context.this_script.split(".")[1].
  • _FULL_SCRIPT_NAME is replaced with what would be context.this_script.
  • #s. can be used and it'll automatically have the seclevel inserted.
  • Subscript and #db methods names are verified.
  • All references to preprocessor syntax functions not being called are turned into arrow function wrappers e.g. let debug = #D; -> let debug = v => #D(v);.
  • _SECLEVEL is replaced with a number (0 to 4) representing the seclevel of the script.
  • When exports are present in the script, it becomes a script that returns an object of the exported values.
    • _EXPORTS becomes an array of the names of the exported values.
• And Neat Weird Fixes
  • Like .__proto__ and .prototype being converted to ["__proto__"] and ["prototype"].
  • Illegal and unsafe strings.
    • Appearences of _SC and friends are either renamed or have an escape inserted so that script is legal.
    • Preprocessor syntax in strings are escaped so hackmud doesn't recognise them as preprocessor syntax.
    • And appearences of // in strings and regexes have a backslash inserted between to stop hackmud's overagressive comment remover from removing half the line of code.
  • Classes are actually usable now, this module replaces instances of this with a variable referencing what would be this.
  • Function.prototype can be referenced (but only the .prototype property, nothing else).
  • Object.getPrototypeOf and Object.setPrototypeOf are replaced with equivalent functions.
