word-researcher v1.0.5

Word researcher

The package aims to search a word inside a text. The tool is based on the KMP (Knuth–Morris–Pratt) algorithm.

The package came with many features like (findOne, findAll, history of search ...etc) and so many others, which some of them are already implemented, and the others will, soon.

Because of type's errors are the most common things developers encounter and deal with, I have used typescript to implement the package, which will make it more reliable to types.

Installation

Use the package manager npm

npm install word-researcher

or for yarn

yarn add word-researcher

Future features

For now, I've just created the find method, and the history of search. I am aiming to include other features rather than the ones mentioned above. The new features will be described down below :

• Replacing the searched word in a text
• Highlighting the searched word in text

Examples

here some examples about the tools provided by the package, I am going to listed them first with a simple description about what it is aiming to do, and then I will provide some examples clearifying their use, and how to combine them if it is possible.

This is the way how to import any tool :

    import { findOne, findAll, findAllWithSkip, history } from "word-researcher";

Description

@param text => string
@param word => string
@param options => Object
@returns position => number

@param text => string
@param word => string
@param options => Object
@returns position => number[]

The previous functionality may take options as an Object {}. The available options are described in the next section down below :

 options = {
    caseSensative: boolean,     # default => false
    skipXFirstResults: number,  # default => 0
    skipXLastResults: number,   # default => 0
 }

skipXFirstResults and skipXLastResults are only valid for findAllWithSkip method.

@param text => string
@param word => string
@param options => Object
@returns position => number[]

@param word => string

@param index => number
@returns => string

@returns => number

Note

each tool provided by this package is implemented independently of any other tool, it's up to the developers to use it the way they find it appropriate.

For example

The history and find tool are separately implemented and do not have any relation to each other, but the user is free to combine them.

import {findOne, history} from "word-researcher";

const text = "this is a new paragraph, it is used only for test";

# find the position of the word.
findOne(text, "is"); #result => 5
# and then store the word into the history
history.pushWord("is");
