Package Exports

ascii-lookup

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ascii-lookup) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

ascii-lookup

Get ASCII characters, html codes, hex codes, and decimal codes for different encodings via decimal code or hex code.

Install

You can install via npm or yarn.

npm

npm install --save ascii-lookup

yarn

yarn add ascii-lookup

Usage

Importing

You can import using ES6 imports. There are two methods: getASCIIItemForDecimal which will return ASCII info by a given decimal, and getASCIIItemForHex which will return ASCII info by a given hex code.

import { getASCIIItemForDecimal, getASCIIItemForHex } from 'ascii-lookup';

Arguments

getASCIIItemForDecimal accepts two arguments:

Parameter	Type	Optional	Description
dec	number	false	The ASCII decimal value
encoding	string (`ASCIIEncoding` enum in Typescript)	true	The type of encoding for the extended ASCII set - Default is UTF8

getASCIIItemForHex also accepts two arguments:

Parameter	Type	Optional	Description
hex	string	false	The ASCII hex value
encoding	string (`ASCIIEncoding` enum in Typescript)	true	The type of encoding for the extended ASCII set - Default is UTF8

Encodings

If you are using TypeScript you can import the ASCIIEncoding enum which will provide you with every supported encoding:

Example

import { getASCIIItemForDecimal, ASCIIEncoding } from 'ascii-lookup';

getASCIIItemForDecimal(128, ASCIIEncoding.CP437);

If you are using plain JavaScript the available encodings are:

Result

Both getASCIIItemForDecimal and getASCIIItemForHex return an object of type ASCIIItem:

Key	Type	Description
dec	number	Decimal code
hex	string	Hex code
html	string	HTML code
char	string	Character

A type for ASCIIItem is available for import in TypeScript:

import { getASCIIItemForDecimal, ASCIIEncoding, ASCIIItem } from 'ascii-lookup';

const result: ASCIIItem = getASCIIItemForDecimal(128, ASCIIEncoding.CP437);
