Object
- LispInterpreter

Constructors

constructor

new LispInterpreter(): LispInterpreter
Constructor.

Returns LispInterpreter
Overrides Object.constructor
- Defined in src/interpreter/LispInterpreter/index.ts:35

Properties

constructor

constructor: Function

The initial value of Object.prototype.constructor is the standard built-in Object constructor.

plugins

plugins: KeiLispPlugin[]

Registered plugins consulted by the evaluator on every call. See use.

root

root: Table

The root (top-level) environment table, pre-populated with built-in symbols.

streamManager

streamManager: StreamManager

The stream manager that owns the interpreter's output / spy streams.

Methods

eval

eval(aCons: LispValue): LispValue
Evaluates the given expression and returns the result. Throws ParseError, EvalError, or ExitError on failure; library users are expected to catch these (see the KeiLispError base class for the parse/eval family).
Parameters
- aCons: LispValue
  the expression to evaluate
Returns LispValue
the evaluation result
- Defined in src/interpreter/LispInterpreter/index.ts:61

evalAll

evalAll(source: string): LispValue[]
Parses the source string, evaluates every expression it contains, and returns the results as an array.
Parameters
- source: string
  the Lisp source string
Returns LispValue[]
the array of evaluation results, one per top-level expression
- Defined in src/interpreter/LispInterpreter/index.ts:78

evalString

evalString(source: string): LispValue
Parses and evaluates the source string and returns the value of the last expression.
Parameters
- source: string
  the Lisp source string
Returns LispValue
the value of the last expression, or Cons.nil for empty input
- Defined in src/interpreter/LispInterpreter/index.ts:89

hasOwnProperty

hasOwnProperty(v: PropertyKey): boolean
Determines whether an object has a property with the specified name.
Parameters
- v: PropertyKey
  A property name.
Returns boolean
Inherited from Object.hasOwnProperty
- Defined in node_modules/.pnpm/typescript@6.0.3/node_modules/typescript/lib/lib.es5.d.ts:138

initializeTable

initializeTable(): Table
Builds the root environment table by pre-registering every built-in symbol and the small set of bootstrap lambdas (append / butlast / nthcdr / reverse).

Returns Table
the freshly initialized root environment
- Defined in src/interpreter/LispInterpreter/index.ts:124

isPrototypeOf

isPrototypeOf(v: Object): boolean
Determines whether an object exists in another object's prototype chain.
Parameters
- v: Object

Returns boolean
Inherited from Object.isPrototypeOf
- Defined in node_modules/.pnpm/typescript@6.0.3/node_modules/typescript/lib/lib.es5.d.ts:144

parse

parse(aString: string): Cons
Parses the given string into a list of top-level expressions and returns it. The result is always a Cons (possibly Cons.nil for empty input) because the source is wrapped in an outer list before parsing. Throws ParseError if the source cannot be parsed.
Parameters
- aString: string
  the Lisp source string
Returns Cons
a Cons containing the parsed top-level expressions
- Defined in src/interpreter/LispInterpreter/index.ts:102

propertyIsEnumerable

propertyIsEnumerable(v: PropertyKey): boolean

  the environment table to install as root
Returns null
null
- Defined in src/interpreter/LispInterpreter/index.ts:111

- Defined in node_modules/.pnpm/typescript@6.0.3/node_modules/typescript/lib/lib.es5.d.ts:126

use

use(plugin: KeiLispPlugin): this

this interpreter, for chaining
