How in node to break a line into a new line ('\ n')?

Question

How in node to break a line into a new line ('\ n')? I have a simple string, for example var a = "test.js\nagain.js" , and I need to get ["test.js", "again.js"] . I tried

 a.split("\n"); a.split("\\n"); a.split("\r\n"); a.split("\r"); 

but nothing above works.

Answer 1

Try splitting it into a regular expression, such as /\r?\n/ , for use on both Windows and UNIX systems.

 > "a\nb\r\nc".split(/\r?\n/) [ 'a', 'b', 'c' ] 

Answer 2

If the file is native to your system (of course, no guarantees for this), then Node can help you:

 var os = require('os'); a.split(os.EOL); 

This is usually more useful for building output strings from Node, although for platform portability.

Answer 3

 a = a.split("\n"); 

---

Note that split ting returns a new array, not just assigning it to the original string. You need to explicitly save it in a variable.

Answer 4

I created an eol module for working with line endings in node or browsers. It has a separation method like

 var lines = eol.split(text) 

Answer 5

The first should work:

 > "a\nb".split("\n"); [ 'a', 'b' ] > var a = "test.js\nagain.js" undefined > a.split("\n"); [ 'test.js', 'again.js' ] 

Answer 6

You need simple quotes

 string.split('\n'); 

Simple quotes work here.
