Could we possibly add a ssv() or wssv()? about d3-dsv

You can make your own using d3.dsvFormat(" ").

thank you. Can it do the fetch as well? Would it be:

d3.text("data.txt")
  .then(txt => ssv.parse(txt))
  .then(data => {

  });

?

Seems like it can't. Seems like it needs to be:

    ssv = d3.dsvFormat("\t ");
    d3.text("multiple.tsv")
        .then(txt => {
            data = ssv.parse(txt)
            console.log(data);

but it seems d3.dsvFormat("\t "); needs to be d3.dsvFormat(" "); -- if there is

    3   \t 4

(some space and a tab) it is not possible to work this way? But if it is:

    ssv = d3.dsvFormat(" ");
    d3.text("multiple.tsv")
        .then(txt => {
            txt = txt.replace(/[\t ]+/g, " ");
            data = ssv.parse(txt);
            console.log(data);

then it can work.

d3.dsvFormat only allows characters as delimiters; it doesn’t support multiple characters or regular expressions as delimiters. You can use space as a delimiter, or tab, but not both.

To fetch and parse a file:

d3.text(url).then(text => ssv.parse(text))

I appreciate it.

I was trying to replicate the case with spaces in front of the first value and this seems to work ok:

    ssv = d3.dsvFormat(" ")
    d3.text("multiple.ssv")
        .then(txt => {
            txt = txt.replace(/[\t ]+/g, " ").replace(/^[ ]/gm, "").replace(/[ ]$/gm, "");
            data = ssv.parse(txt);
            console.log(data);
