slashes's Issues

\r\n

Hello,

First of all, thank you for this plugin.

I had trouble with the following snippet using \r\n:

var slashes = require( "slashes" );
var str = "Hello,\\r\\nworld!";
console.log( slashes.strip( str ) );

The expected result was

Hello,
world!

But I got

Hello,r
world!

Option to control literal character escapes

If set options.n = false, I would expect the sequence "\n" to be retained in the output. Instead, the sequence "\n" is interpreted as simply any other non-metacharacter, and replaced with "n". This behaviour should be switchable.

addSlashes fails on unicode

addSlashes('\ud83d\ude0a', { escapeNonAscii: true })
"😊" // should be '\\ud83d\\ude0a'
stripSlashes('\\ud83d\\ude0a')
"😊" // ok

problem: in str = str.replace(rx, char => {,
the rx regex does not match unicode chars, only chars from options.characters

my solution:

var backslashEncode = (function backslashEncodeFactory() {
  const escapeCode = Array(32);
  for (let i = 0; i < 32; i++)
    escapeCode[i] = '\\x'+i.toString(16).padStart(2, '0');
  escapeCode[0] = '\\0';
  escapeCode[8] = '\\b'; escapeCode[9] = '\\t'; escapeCode[10] = '\\n';
  escapeCode[11] = '\\v'; escapeCode[12] = '\\f'; escapeCode[13] = '\\r';
  
  return function backslashEncode(str) {
    let res = '';
    for (let i = 0; i < str.length; i++) {
      const char16bit = str[i];
      const code = char16bit.charCodeAt(0);
      res += (
        (code < 32) ? escapeCode[code] : // ascii control
        (code == 92) ? '\\\\' :
        (code < 128) ? char16bit : // ascii printable
        '\\u'+code.toString(16).padStart(4, '0') // unicode
      );
    }
    return res;
  }
})();

test

backslashEncode('\ud83d\ude0a')
'\\ud83d\\ude0a'

backslashEncode('\n \t \\ \r \b \v \f \0 ß ä € § ` ´')
'\\n \\t \\\\ \\r \\b \\v \\f \\0 \\u00df \\u00e4 \\u20ac \\u00a7 ` \\u00b4'

backslashEncode('\x19 \x18 \x17 \x16 \x15 \x14 \x13 \x12 \x11 \x10 \x0f \x0e')
'\\x19 \\x18 \\x17 \\x16 \\x15 \\x14 \\x13 \\x12 \\x11 \\x10 \\x0f \\x0e'

backslashEncode('\x0d \x0c \x0b \x0a \x09 \x08 \x07 \x06 \x05 \x04 \x03 \x02 \x01 \x00')
'\\r \\f \\v \\n \\t \\b \\x07 \\x06 \\x05 \\x04 \\x03 \\x02 \\x01 \\0'

i assume that array access is faster than map.get

could be made faster with a regex
that matches all 65536 char16bit except the 95 printable ascii chars
like str = str.replace(/[^abcdefgh]/, char16bit => {,

import { addSlashes, removeSlashes } from 'slashes'
         ^^^^^^^^^^
SyntaxError: Named export 'addSlashes' not found. The requested module 'slashes' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'slashes';
const { addSlashes, removeSlashes } = pkg;

fix: add "type": "module", to node_modules/slashes/package.json

then node says

Error [ERR_MODULE_NOT_FOUND]: Cannot find module 'node_modules/slashes/lib/module/add-slashes' imported from node_modules/slashes/lib/module/index.js

fix: add .js extension to imports
