@yozora/tokenizer-ecma-import parses supported single-line ECMAScript import declarations into EcmaImport nodes. Side-effect, default, named, and aliased named imports are supported:

import '@yozora/parser'
import Parser from '@yozora/parser'
import Parser, { YozoraParserProps } from '@yozora/parser'
import { YozoraParserProps } from '@yozora/parser'
import { YozoraParser, YozoraParser as Parser } from '@yozora/parser'

Namespace, type-only, and multiline imports, identifiers containing escape sequences, and string-named imports are not supported:

import * as Parser from '@yozora/parser'
import type Parser from '@yozora/parser'
import {
  Parser
} from '@yozora/parser'
import \u0050arser from '@yozora/parser'
import { 'parser-name' as Parser } from '@yozora/parser'

See documentation for details.

Install

npm install --save @yozora/tokenizer-ecma-import

Usage

@yozora/tokenizer-ecma-import is built into @yozora/parser.

With DefaultParser

A tokenizer must be registered with an IParser before use.

import { DefaultParser } from '@yozora/core-parser'
import ParagraphTokenizer from '@yozora/tokenizer-paragraph'
import TextTokenizer from '@yozora/tokenizer-text'
import EcmaImportTokenizer from '@yozora/tokenizer-ecma-import'

const parser = new DefaultParser()
  .useFallbackTokenizer(new ParagraphTokenizer())
  .useFallbackTokenizer(new TextTokenizer())
  .useTokenizer(new EcmaImportTokenizer())

parser.parse(`
import { Parser } from '@yozora/parser'
import { Button } from '@material-ui/core'
import Markdown from '@yozora/react-markdown'
`)

With @yozora/parser

import YozoraParser from '@yozora/parser'

const parser = new YozoraParser()
parser.parse(`
import { Parser } from '@yozora/parser'
import { Button } from '@material-ui/core'
import Markdown from '@yozora/react-markdown'
`)

With @yozora/parser-gfm

import GfmParser from '@yozora/parser-gfm'
import EcmaImportTokenizer from '@yozora/tokenizer-ecma-import'

const parser = new GfmParser()
parser.useTokenizer(new EcmaImportTokenizer())
parser.parse(`
import { Parser } from '@yozora/parser'
import { Button } from '@material-ui/core'
import Markdown from '@yozora/react-markdown'
`)

With @yozora/parser-gfm-ex

import GfmExParser from '@yozora/parser-gfm-ex'
import EcmaImportTokenizer from '@yozora/tokenizer-ecma-import'

const parser = new GfmExParser()
parser.useTokenizer(new EcmaImportTokenizer())
parser.parse(`
import { Parser } from '@yozora/parser'
import { Button } from '@material-ui/core'
import Markdown from '@yozora/react-markdown'
`)

Options

| Name | Type | Required | Default | | :--------- | :------- | :------- | :-------------------------------- | | name | string | No | "@yozora/tokenizer-ecma-import" | | priority | number | No | TokenizerPriority.ATOMIC |

• name: Unique tokenizer name. Generated tokens retain it so the parser can dispatch later phases to the same tokenizer.

• priority: Processing priority. Tokenizers with higher values run first. During block matching, a higher-priority tokenizer can interrupt a lower-priority tokenizer.
