nlcst utility to check if a node is meant literally.

Useful if a tool wants to exclude values that are possibly void of meaning. For example, a spell-checker could exclude these literal words, thus not warning about “monsieur”.

Install

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required.

npm:

npm install nlcst-is-literal

Use

Say we have the following file, example.txt:

The word “foo” is meant as a literal.

The word «bar» is meant as a literal.

The word (baz) is meant as a literal.

The word, qux, is meant as a literal.

The word — quux — is meant as a literal.

And our script, example.js, looks as follows:

import {readSync} from 'to-vfile'
import {unified} from 'unified'
import retextEnglish from 'retext-english'
import {visit} from 'unist-util-visit'
import {toString} from 'nlcst-to-string'
import {isLiteral} from 'nlcst-is-literal'

const file = readSync('example.txt')

const tree = unified().use(retextEnglish).parse(file)

visit(tree, 'WordNode', visitor)

function visitor(node, index, parent) {
  if (isLiteral(parent, index)) {
    console.log(toString(node))
  }
}

Now, running node example yields:

foo
bar
baz
qux
quux

API

This package exports the following identifiers: isLiteral. There is no default export.

isLiteral(parent, index|child)

Check if the child in parent is enclosed by matching delimiters. If index is given, the child of parent at that index is checked.

For example, foo is literal in the following samples:

  • Foo - is meant as a literal.
  • Meant as a literal is - foo.
  • The word “foo” is meant as a literal.
