Usage

Install

# yarn
yarn add sh-syntax

# npm
npm i sh-syntax

API

// node
import { parse, print } from 'sh-syntax'

const text = "echo 'Hello World!'"
const ast = await parse(text)
const newText = await print(ast, {
  // `originalText` is required for now, hope we will find better solution later
  originalText: text,
})
// browser
import { getProcessor } from 'sh-syntax'

const processor = getProcessor(() =>
  fetch('sh-syntax/main.wasm').then(res => res.arrayBuffer()),
)

const parse = (text, options) => processor(text, options)

const print = (textOrAst, options) => {
  if (typeof textOrAst === 'string') {
    return processor(textOrAst, {
      ...options,
      print: true,
    })
  }
  return processor(textOrAst, options)
}

// just like node again
const text = "echo 'Hello World!'"
const ast = await parse(text)
const newText = await print(ast, { originalText: text })
