didYouMean.js - A simple JavaScript matching engine
|
||||
===================================================
|
||||
|
||||
[Available on GitHub](https://github.com/dcporter/didyoumean.js).
|
||||
|
||||
A super-simple, highly optimized JS library for matching human-quality input to a list of potential
|
||||
matches. You can use it to suggest a misspelled command-line utility option to a user, or to offer
|
||||
links to nearby valid URLs on your 404 page. (The examples below are taken from a personal project,
|
||||
my [HTML5 business card](http://dcporter.aws.af.cm/me), which uses didYouMean.js to suggest correct
|
||||
URLs from misspelled ones, such as [dcporter.aws.af.cm/me/instagarm](http://dcporter.aws.af.cm/me/instagarm).)
|
||||
Uses the [Levenshtein distance algorithm](https://en.wikipedia.org/wiki/Levenshtein_distance).
|
||||
|
||||
didYouMean.js works in the browser as well as in node.js. To install it for use in node:
|
||||
|
||||
```
|
||||
npm install didyoumean
|
||||
```
|
||||
|
||||
|
||||
Examples
|
||||
--------
|
||||
|
||||
Matching against a list of strings:
|
||||
```
|
||||
var input = 'insargrm'
|
||||
var list = ['facebook', 'twitter', 'instagram', 'linkedin'];
|
||||
console.log(didYouMean(input, list));
|
||||
> 'instagram'
|
||||
// The method matches 'insargrm' to 'instagram'.
|
||||
|
||||
input = 'google plus';
|
||||
console.log(didYouMean(input, list));
|
||||
> null
|
||||
// The method was unable to find 'google plus' in the list of options.
|
||||
```
|
||||
|
||||
Matching against a list of objects:
|
||||
```
|
||||
var input = 'insargrm';
|
||||
var list = [ { id: 'facebook' }, { id: 'twitter' }, { id: 'instagram' }, { id: 'linkedin' } ];
|
||||
var key = 'id';
|
||||
console.log(didYouMean(input, list, key));
|
||||
> 'instagram'
|
||||
// The method returns the matching value.
|
||||
|
||||
didYouMean.returnWinningObject = true;
|
||||
console.log(didYouMean(input, list, key));
|
||||
> { id: 'instagram' }
|
||||
// The method returns the matching object.
|
||||
```
|
||||
|
||||
|
||||
didYouMean(str, list, [key])
|
||||
----------------------------
|
||||
|
||||
- str: The string input to match.
|
||||
- list: An array of strings or objects to match against.
|
||||
- key (OPTIONAL): If your list array contains objects, you must specify the key which contains the string
|
||||
to match against.
|
||||
|
||||
Returns: the closest matching string, or null if no strings exceed the threshold.
|
||||
|
||||
|
||||
Options
|
||||
-------
|
||||
|
||||
Options are set on the didYouMean function object. You may change them at any time.
|
||||
|
||||
### threshold
|
||||
|
||||
By default, the method will only return strings whose edit distance is less than 40% (0.4x) of their length.
|
||||
For example, if a ten-letter string is five edits away from its nearest match, the method will return null.
|
||||
|
||||
You can control this by setting the "threshold" value on the didYouMean function. For example, to set the
|
||||
edit distance threshold to 50% of the input string's length:
|
||||
|
||||
```
|
||||
didYouMean.threshold = 0.5;
|
||||
```
|
||||
|
||||
To return the nearest match no matter the threshold, set this value to null.
|
||||
|
||||
### thresholdAbsolute
|
||||
|
||||
This option behaves the same as threshold, but instead takes an integer number of edit steps. For example,
|
||||
if thresholdAbsolute is set to 20 (the default), then the method will only return strings whose edit distance
|
||||
is less than 20. Both options apply.
|
||||
|
||||
### caseSensitive
|
||||
|
||||
By default, the method will perform case-insensitive comparisons. If you wish to force case sensitivity, set
|
||||
the "caseSensitive" value to true:
|
||||
|
||||
```
|
||||
didYouMean.caseSensitive = true;
|
||||
```
|
||||
|
||||
### nullResultValue
|
||||
|
||||
By default, the method will return null if there is no sufficiently close match. You can change this value here.
|
||||
|
||||
### returnWinningObject
|
||||
|
||||
By default, the method will return the winning string value (if any). If your list contains objects rather
|
||||
than strings, you may set returnWinningObject to true.
|
||||
|
||||
```
|
||||
didYouMean.returnWinningObject = true;
|
||||
```
|
||||
|
||||
This option has no effect on lists of strings.
|
||||
|
||||
### returnFirstMatch
|
||||
|
||||
By default, the method will search all values and return the closest match. If you're simply looking for a "good-
|
||||
enough" match, you can set your thresholds appropriately and set returnFirstMatch to true to substantially speed
|
||||
things up.

----------------------------
