## APIs

### `function endOfLine(): string`

Determine the OS-specific end-of-line marker. Equivalent to [os.EOL](https://nodejs.org/api/os.html#os_os_eol).

### `function endOfLine(text: string): string`

Determine end-of-line marker for a given text. The following markers will be recognized:

- `\n`
- `\r\n`
- `\r`
- `\n\r`

If there is no EOL found, [os.EOL](https://nodejs.org/api/os.html#os_os_eol) will be returned.

### `function endOfLineForFile(filePath: string): string`

Determine end-of-line marker for a given file.

If file doesn't exist or cannot be read, [os.EOL](https://nodejs.org/api/os.html#os_os_eol) will be returned.
