Crate detect_newline 

detect-newline — detect and normalize line endings

Detect which line ending a string uses (\n, \r\n, or \r), normalize a string to one style, count the styles, iterate lines (splitting on all three), and trim trailing newlines. Zero dependencies and no_std. A Rust take on Node’s detect-newline.

use detect_newline::{detect, dominant, to_lf, Newline};

assert_eq!(detect("a\r\nb"), Some(Newline::CrLf));   // first newline found
assert_eq!(dominant("a\nb\nc\r\nd"), Some(Newline::Lf)); // most common
assert_eq!(to_lf("a\r\nb\rc"), "a\nb\nc");            // normalize

\r\n is always treated as a single line ending, never as a \r followed by a \n. detect returns the first ending found; dominant returns the most frequent (ties broken by which occurs first).

Structs

Counts

How many of each line-ending style a string contains. See count.

Lines

Iterator over the lines of a string. Created by lines.

Enums

Newline

A line-ending style.

Functions

count

Count each line-ending style in text.

detect

Detect the first line ending in text, or None if it has none.

dominant

Detect the most frequent line ending in text, or None if it has none.

has_trailing_newline

Whether text ends with a line ending.

lines

Iterate the lines of text, splitting on \n, \r\n, and lone \r.

normalize

Replace every line ending in text with to.

strip_trailing_newline

Strip a single trailing line ending (\r\n, \n, or \r) from text.

to_cr

Normalize every line ending in text to \r.

to_crlf

Normalize every line ending in text to \r\n.

to_lf

Normalize every line ending in text to \n.
