JavaScript / TypeScript API

nerdamer/parser

Programmatic parser access and settings for JavaScript and TypeScript. This is separate from Nerdamer expression syntax.

Direct npm import. The items on this page are JavaScript / TypeScript exports from nerdamer/parser. For functions used inside nerdamer('...'), see Nerdamer Notation.

Interfaces

Operator: unknownInterface

Operator metadata accepted by the parser registry. Registration accepts custom action names and the legacy prefix/postfix aliases. Prefix, postfix, and iteration flags are optional because the parser supplies defaults.

OperatorDefinition: unknownInterface

Operator metadata accepted by the parser registry. Registration accepts custom action names and the legacy prefix/postfix aliases. Prefix, postfix, and iteration flags are optional because the parser supplies defaults.

ParserAPI: unknownInterface

Supported high-level parser surface. Tokenization, RPN conversion, and parser-stack machinery remain internal implementation details even though Nerdamer itself uses them across modules.

Types

JsFunction: unknownType

Type exported by Nerdamer.

OptionsObject: unknownType

Type exported by Nerdamer.

OptionValue: unknownType

Type exported by Nerdamer.

ParserConstants: unknownType

Type exported by Nerdamer.

ParserValuesObject: unknownType

Type exported by Nerdamer.

Variable

Parser: ParserAPIVariable

Shared parser exposed through the supported high-level interface. The implementation accepts a broader compatibility settings bag; this facade exposes only the named settings defined by SettingsType.

APIs

BinaryArithmeticOperation: "pow" | "times" | "div" | "minus" | "plus"API

The supported operator actions

ComparisonOperation: "eq" | "lt" | "lte" | "gt" | "gte"API

API exported by Nerdamer.

Language: "eng" | "spa" | "fra" | "deu" | "por" | "ita" | "nld"API

API exported by Nerdamer.

Operation(a: ParserEntity, b?: ParserEntity): ParserEntityAPI

The type used to defined a operation function for the parser

OperatorAction: "dot" | "doubleFactorial" | "factorial" | "mod" | "percent" | BinaryArithmeticOperation | "setEqual" | ComparisonOperation | "mapTo" | "comma" | "assign" | "functionAssign" | "in"API

API exported by Nerdamer.

PostFixFunction(b: ParserEntity): ParserEntityAPI

The type used to defined a prefix for the parser

PreFixFunction(a: ParserEntity): ParserEntityAPI

The type used to defined a prefix for the parser

SettingsType: Omit<InternalSettingsType, "DEFER_SIMPLIFICATION">API

Parser settings supported by the public parser facade. DEFER_SIMPLIFICATION remains an internal compatibility setting and is not part of the supported 2.0 parser API.
