detect-newline
Advanced tools
Package description
The detect-newline npm package is designed to help developers identify the type of newline character used in a string. This can be particularly useful when working with text data that originates from different operating systems, as Unix, Windows, and old Mac systems use different characters for line breaks (`\n` for Unix/Linux, `\r\n` for Windows, and `\r` for old Mac). The package provides a simple interface to detect the newline character and can also gracefully handle mixed or absent newlines.
Detect the most common newline character in a string
This feature allows you to detect the most common newline character in a given string. If the string contains mixed newline characters, the most common one is returned. If there's a tie, `\n` is returned by default.
"const detectNewline = require('detect-newline');\nconst mixedNewlines = 'Hello\r\nWorld\nHello World';\nconsole.log(detectNewline(mixedNewlines)); // '\r\n'"Detect the newline character used at the end of a string
This functionality is useful for determining the newline character at the end of a string, which can be critical for appending lines to files or data streams while maintaining consistency with the existing newline format.
"const detectNewline = require('detect-newline');\nconst stringWithNewlineAtEnd = 'Hello World\n';\nconsole.log(detectNewline(stringWithNewlineAtEnd)); // '\n'"Similar to detect-newline, newline-detect also provides functionality for detecting newline characters within strings. The main difference may lie in the implementation details or additional features offered by one package over the other.
The eol package offers more comprehensive handling of newline characters, including detection, conversion, and normalization across different operating systems. While detect-newline focuses on detection, eol provides a broader set of tools for working with end-of-line characters.
