Ocnparse

OcnParse is a set of tokenizing tools compatible with Baha'i terms Since \b in regex cannot deal with words that include unicode, dashes or single quotes

Install the interface module into your node project with:

npm install --save ocnparse

Functionality

// import the parser 
const parser = require('ocnparse')  

parser.tokenize(str, tag='')
// returns array of tokens, each an object with three properties: prefix, word and suffix. 
// .prefix and .suffix contain any punctuation or markup. 
// .word contains the core word (which can also contain <u> markup).
// include a tag if the string being parsed is already word-wrapped (this preserves wrapper tag attributes)

parser.rebuild(tokens, tag='')
// returns the reconstructed text with some options for inserting changes
// include a tag if you want to wrap each word 
// wrapper tags contain any classes in token.info.class[] and data attrs in token.data.data{}

parser.reWrap(str, srcTag='w', destTag='')
// helper function to parse wrapped text, correct tokens and output new word-wrapped string 
// user can use this whenever text is edited -- or change the wrapper tags easily 
// preserves wrapper class and data attributes

Implementation Example:

const parser = require('ocnparse')  

// For example, say we want to wrap each word in a <span>...</span>
let tokens = parser.tokenize("Four score!!!") 
let result = parser.rebuild(tokens, 'span')
// result: "<span>Four </span><span>score!!!</span>"

// For example, say we want to rewrap words wrapped in <span>...</span> to <w>...</w>
let str = `<span class='first'>Four </span><span data-whatever='12'>score!!!</span>`
let result = parser.rewrap(str, 'span', 'w')
// result: `<w class="first">Four </w><w data-whatever="12">score!!!</w>`

// Or our wrapped phrase has been edited and we need to re-wrap to correct it
let str = `Hmm. <span class="first">Four three </span><span data-whatever="12">score!!!</span>`
let result = parser.rewrap(str, 'span')
// result: `<span>Hmm. </span><span class="first">Four </span><span>three </span><span data-whatever="12">score!!!</span>`
