Pluralize/singularize a sentence using the compromise library in javascript

Question

I'm trying to use the compromise library to pluralize/singularize sentences that take these forms:

const str1 = "10 dog";
const str2 = "a man and 3 cat";
const str3 = "a bear";

If I use the pluralize method from compromise, it returns the list of plural nouns or verbs, but I'm trying to figure out how to get it to pluralize the entire string.

const nlp = require("compromise");
const doc = nlp(str2);
const finalStr = doc.nouns().toPlural().out("normal"); // "man cats" instead of "a man and 3 cats";

This will work because it will identify all the nouns first:

doc.match("#Noun").nouns().toPlural().out("normal");

I see where the problem came from. Take a look at below two console logs:

const nlp = require("compromise")
let doc = nlp("a man and 3 cat")
doc.match("#Noun").nouns().toPlural()
console.log(doc.out("normal")) // "a man and 3 cats"

let doc2 = doc.match("#Noun").nouns().toPlural()
console.log(doc2.out("normal")) // "man cats"

Note that in the second example, I am saving it into a new variable. So I guess .match("#Noun") was not necessary, and you were right the first time -- just don't save it into finalStr.

It looks like I had a typo in my comment. Your code produces `"man cats"` instead of `"a man and 3 cats"`. Maybe I'm using the wrong library? – Kevin Whitaker Dec 03 '18 at 16:38
@KevinWhitaker Maybe check the version? https://runkit.com/kkj6781/nlp-compromise-tosingular-toplural – Peter Kim Dec 03 '18 at 16:42
@KevinWhitaker Updated my answer. Please see the edited part. – Peter Kim Dec 03 '18 at 16:48
that worked. Weird - I guess saving it to a new variable mutates it somehow. Thanks! – Kevin Whitaker Dec 03 '18 at 16:52
