Newline character converter node module for JavaScript or TypeScript

• npm install eol
• let eol = require("eol")
• import eol from "eol"

• Normalize line endings in text to match the current operating system
• Returns string with line endings normalized to \r\n or \n

• Normalize line endings in text to CRLF (Windows, DOS)
• Returns string with line endings normalized to \r\n

• Normalize line endings in text to LF (Unix, OS X)
• Returns string with line endings normalized to \n

• Normalize line endings in text to CR (Mac OS)
• Returns string with line endings normalized to \r

• Generate normalizer where linebreaks become text
• Used internally to generate the normalizers above
• Returns composed pure function with creative potential

• Add linebreak before text
• Returns string with linebreak added before text
• Uses eol.auto linebreak
• eol.lf(eol.before(text)) ⋮

• Add linebreak after text
• Returns string with linebreak added after text
• Uses eol.auto linebreak
• eol.lf(eol.after(text)) ⋮

• Detect or inspect linebreaks in text
• Returns array of matched linebreaks

• Split text by newline
• Returns array of lines

Coercing normalizers to string yields the appropriate character...useful glue for joining

String(eol.lf) // "\n"
eol.split(text).join(eol.auto) // === eol.auto(text)
eol.split(text).filter(line => line).join(eol.auto) // text joined after removing empty lines
eol.split(text).slice(-3).join(eol.auto) // last 3 lines joined

Detect or inspect via match

eol.match(" ") // []
eol.match("world\nwide\nweb") // ["\n","\n"]

Generate alternate normalizers

let extra = eol.dub("\n\n\n")
extra("...")

let huh = eol.dub("???")
huh("...")

let eol = require("eol")
let edit = require("edit-file")

edit("sample.txt", eol.lf)

let eol = require("eol")
let map = require("map-file")

map({
  from: "from.txt",
  to: "to.txt",
  map: eol.lf
})

let ssv = require("ssv")
let eol = require("eol")

let deep = eol.split("spaced.txt").map(ssv.split)

Have an eol sample to share?
