Newline character converter node module for JavaScript or TypeScript

npm.im/eol

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

API

eol.auto(text)

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

eol.crlf(text)

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

eol.lf(text)

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

eol.cr(text)

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

eol.dub(text)

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

eol.before(text)

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

eol.after(text)

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

eol.match(text)

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

eol.split(text)

• Split text by newline
• Returns array of lines

Joining

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 lineseol.split(text).slice(-3).join(eol.auto)// last 3 lines joined

Matching

Detect or inspect via match

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

Dubbing

Generate alternate normalizers

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

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