Advanced trimming of strings by providing lists of characters or full strings.

Just run the following command:

npm install trimfandango

The basic syntax:

Function trimFandango(String text, (Array|String charlist)): String

The trimFandango() function removes a set of characters from both ends of a string. By default it removes all whitespaces characters: nul-bytes, ordinary whitespaces, horizontal and vertical tabs, new lines and carriage returns. It returns the trimmed string.

• 0x00, ASCII 00, NUL-byte
• 0x09, ASCII 09, tab
• 0x0A, ASCII 10, new line/line feed
• 0x0B, ASCII 11, vertical tab
• 0x0D, ASCII 13, carriage return
• 0x20, ASCII 32, whitespace
• 0xA0, ASCII 160, no-break space

Change the trimming behaviour by optionally providing a charlist. The charlist can be an Array or any other value. Be aware, that any other value than an array will be converted to a string.

If you provide an array of single characters, all matched characters in any order will be removed from the beginning and the end of the string. You can either provide normal characters, unicode or specific regular expression tokens. In case of tokens take care that you double-backslash them, i.e. \\s instead of \s.

const trimFandango = require('trimfandango')

console.log(
    trimFandango(
        '#55  ### #55 55§5   FOOBAR   # 55§&    ',
        ["\\s","#","&","5","§"]
    )
)

The output:

FOOBAR

If you provide a string of characters - or any other value that converts to a string - the string and its possible subsets will removed from both ends of the text.

const trimFandango = require('trimfandango')

console.log(
    trimFandango(
        '12FOOBAR23',
        123
    )
)

The output:

FOOBAR

1. trimfandango is heavily inspired by the trim() function of PHP.
2. The name is a reminiscence to Grim Fandango, authored by the awesome Tim Schafer.
3. This is a pure package without any dependencies, excutable in the frontend and backend.
