Option comment_no_infix

The comment_no_infix option restricts the definition of comments to full lines. Comment characters defined in the middle of a line are not interpreted as such.

Comments are disabled by default. Thus, this option only takes effect when comments are activated.

• Type: boolean
• Optional
• Default: false
• Since: 5.5.0

Example

While the default behavior generates [ [ 'a', 'b' ] ], activating comment_no_infix in the example below disregards the comment character present in the second line.

import assert from "node:assert";
import dedent from "dedent";
import { parse } from "csv-parse/sync";

const output = parse(
  dedent`
    # Illustrate the usage of comment_no_infix
    a,b#,c
  `,
  {
    comment: "#",
    comment_no_infix: true,
  },
);

assert.deepStrictEqual(output, [["a", "b#", "c"]]);
