# LiquidMetal
[A mimetic poly-alloy](https://youtu.be/Fa4Jq7gJvZ0) of the Quicksilver
scoring algorithm, essentially LiquidMetal. ``Flex matching short abbreviations against longer strings is a boon in
productivity for typists. Applications like
[Quicksilver](http://www.qsapp.com/), [Alfred](http://www.alfredapp.com/),
[LaunchBar](http://www.obdev.at/products/launchbar/index.html), and
[Launchy](http://www.launchy.net/) have made this method of keyboard entry a
popular one. It's time to bring this same functionality to web controls.
LiquidMetal makes scoring long strings against abbreviations easy.## Usage
Include the library:
Score any string against an abbreviation:
LiquidMetal.score("FooBar", "foo") //=> 0.950
LiquidMetal.score("FooBar", "fb") //=> 0.917
LiquidMetal.score("Foo Bar", "fb") //=> 0.929
LiquidMetal.score("Foo Bar", "baz") //=> 0.0
LiquidMetal.score("Foo Bar", "") //=> 0.8All scores fall between a range of 0.0 (no match) to 1.0 (perfect match).
## Inspired By
* [Quicksilver](http://code.google.com/p/blacktree-alchemy/) and its [scoreForAbbreviation algorithm](http://code.google.com/p/blacktree-alchemy/source/browse/trunk/Crucible/Code/NSString_BLTRExtensions.m#61) by Alcor
* [Quicksilver.js](http://rails-oceania.googlecode.com/svn/lachiecox/qs_score/trunk/qs_score.js) by [Lachie Cox](http://smartbomb.com.au/2008/02/11/quicksilver-javascript)## Why?
* To satisfy my own requirements for the
[jquery.flexselect](http://rmm5t.github.io/jquery-flexselect) plugin
* The Quicksilver algorithm doesn't give proper weight to abbreviations that
match the first character of the scored string.
* The Quicksilver algorithm is extremely slow for certain length
string/abbreviation combinations because of its use of recursion. While
slightly slower for shorter length string/abbreviation combinations,
LiquidMetal outperforms the Quicksilver algorithm by orders of magnitude under
other conditions.
* The javascript version of the Quicksilver algorithm (Quicksilver.js) is case
sensitive and doesn't give added weight to camel case strings; whereas,
LiquidMetal is case insensitive and does give added weight to uppercase
letters in camel case strings.## Todo
* More tests
* Consider tweaking the scores for "trailing" characters
* Improve implementation of highest score matching (LiquidMetal
currently returns the highest scoring match for an abbreviation,
but is inefficient)
* See if it's possible to tune the performance further## Author
