Natural language parser, for the Dutch language, that produces nlcst.
This package exposes a parser that takes Dutch natural language and produces a syntax tree.
If you want to handle Dutch natural language as syntax trees manually, use this.
Alternatively, you can use the retext plugin retext-dutch, which wraps this project to also parse natural language at a higher-level (easier) abstraction.
For English or most Latin-script languages, you can instead use parse-english or parse-latin.
This package is ESM only. In Node.js (version 16.0+), install with npm:
In Deno with esm.sh:
import {ParseDutch} from 'https://esm.sh/parse-dutch@7'
In browsers with esm.sh:
<script type="module">
import {ParseDutch} from 'https://esm.sh/parse-dutch@7?bundle'
</script>
import {inspect} from 'unist-util-inspect'
import {ParseDutch} from 'parse-dutch'
const tree = new ParseDutch().parse(
'Kunt U zich ’s morgens melden bij het afd. hoofd dhr. Venema?'
)
console.log(inspect(tree))

This package exports the identifier ParseDutch. There is no default export.
Create a new parser.
ParseDutch extends ParseLatin. See parse-latin for API docs.
All of parse-latin is included, and the following support for the Dutch natural language:
gr., sec., min., ma., vr., vrij., febr., mrt., and more)Mr., Mv., Sr., Em., bijv., zgn., amb., and more)d’, ’n, ’ns, ’t, ’s, ’er, ’em, ’ie, and more)This package is fully typed with TypeScript. It exports no additional types.
Projects maintained by me are compatible with maintained versions of Node.js.
When I cut a new major release, I drop support for unmaintained versions of Node. This means I try to keep the current release line, parse-dutch@^7, compatible with Node.js 16.
This package is safe.
