Does not work for $

[timvandam]

I am trying to replace each newline with </s>, and to also add </s> to the very end. However if it ends with a newline I only want one </s>.

I wrote a regular expression for this using $, however this does not seem supported.

Some sample code (TS):

(async function test() {
    console.log('runnig test');
    const text = `
first line
second line
third line`.trimStart();
    let result = '';
    const readStream = Readable
        .from(text)
        .pipe(replaceStream(/\s*[\n\r]+|$/g, ' </s>'));
    const writable = new Writable({
        write(chunk: string) {
            result += chunk;
        }
    });

    readStream.pipe(writable);
    await finished(readStream);

    console.log('Done! Result:');
    console.log('---')
    console.log(result);
    console.log('---')
})();
