Invalid parsing of empty numeric columns at end of line

[mattosborn]

If the last column in a line is numeric and empty, and the linebreak is \r\n, the column will be parsed to 0 instead of null / empty.

import { inferSchema, initParser } from "udsv";

const csvStr = `
id,col1,col2
a,1,2
b,2,
c,3,\r\nd,4,\ne,5,
`.trim();

const schema = inferSchema(csvStr);
const parser = initParser(schema);

const data = parser.typedDeep(csvStr);

This will parse to:

[
  { id: 'a', col1: 1, col2: 2 },
  { id: 'b', col1: 2, col2: null },
  { id: 'c', col1: 3, col2: 0 },
  { id: 'd', col1: 4, col2: null },
  { id: 'e', col1: 5, col2: null }
]

replying from phone, so cannot test, but i see you're inter-mixing line delimiters between \n and \r\n. this is currently not supported, so could be causing the issue. can you check if this works properly with uniform line delimiters?

[leeoniya]

yes, this appears to be an issue with mixed line endings. i don't plan to support this.

with uniform line endings it works correctly: https://jsfiddle.net/ew5xcb0s/
