nlcst utility to check if a node is meant literally.
Contents
What is this?
This utility can check if a node is meant literally.
When should I use this?
This package is a tiny utility that helps when dealing with words. It’s 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. In Node.js (version 16+), install with npm:
npm install nlcst-is-literal
In Deno with esm.sh
:
import {isLiteral} from 'https://esm.sh/nlcst-is-literal@3'
In browsers with esm.sh
:
<script type="module">
import {isLiteral} from 'https://esm.sh/nlcst-is-literal@3?bundle'
</script>
Use
Say our document example.txt
contains:
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 module example.js
looks as follows:
import {read} from 'to-vfile'
import {ParseEnglish} from 'parse-english'
import {visit} from 'unist-util-visit'
import {toString} from 'nlcst-to-string'
import {isLiteral} from 'nlcst-is-literal'
const file = await read('example.txt')
const tree = new ParseEnglish().parse(String(file))
visit(tree, 'WordNode', function (node, index, parent) {
if (isLiteral(parent, index)) {
console.log(toString(node))
}
})
…now running node example.js
yields:
foo
bar
baz
qux
quux
API
This package exports the identifier isLiteral
.
There is no default export.
isLiteral(parent, index|child)
Check if the child in parent
at index
is enclosed by matching delimiters.
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.
Parameters
parent
(Node
) — parent nodeindex
(number
) — index of child in parentchild
(Node
) — child node of parent
Returns
Whether the child is a literal (boolean
).
Types
This package is fully typed with TypeScript. It exports no additional types.
Compatibility
Projects maintained by the unified collective are compatible with maintained versions of Node.js.
When we cut a new major release, we drop support for unmaintained versions of
Node.
This means we try to keep the current release line, nlcst-is-literal@^3
,
compatible with Node.js 16.
