Fuzzy filtering and string scoring

fuzzaldrin

Fuzzy filtering and string scoring.

This library is used by Atom and so its focus will be on scoring and filtering paths, methods, and other things common when writing code. It therefore will specialize in handling common patterns in these types of strings such as characters like /, -, and _, and also handling of camel cased text.

npm install fuzzaldrin

Sort and filter the given candidates by matching them against the given query.

  • candidates - An array of strings or objects.
  • query - A string query to match each candidate against.
  • options - An optional object with the following keys:
    • key - The property to use for scoring if the candidates are objects.
    • maxResults - The maximum numbers of results to return.

Returns an array of candidates sorted by best match against the query.

{filter} = require 'fuzzaldrin'
 
# With an array of strings 
candidates = ['Call''Me''Maybe']
results = filter(candidates'me')
console.log(results) # ['Me', 'Maybe'] 
 
# With an array of objects 
candidates = [
  {name: 'Call'id: 1}
  {name: 'Me'id: 2}
  {name: 'Maybe'id: 3}
]
results = filter(candidates'me'key: 'name')
console.log(results) # [{name: 'Me', id: 2}, {name: 'Maybe', id: 3}] 

Score the given string against the given query.

  • string - The string the score.
  • query - The query to score the string against.
{score} = require 'fuzzaldrin'
 
score('Me''me')    # 0.17099999999999999 
score('Maybe''me') # 0.0693
