Usage

Parameters

str                       (required)
requiredSubstrings        (required)
allowLastSubstringToBleed (optional) default = false

Requiring

const hasRequiredSubstrings = require('@pelevesque/has_required_substrings')

Basic Usage

requiredSubstrings is an array of substrings. true is returned if all substrings are found.

const str = 'abcde'
const requiredSubstrings = ['f']
const result = hasRequiredSubstrings(str, requiredSubstrings)
// result === false
const str = 'abcde'
const requiredSubstrings = ['a']
const result = hasRequiredSubstrings(str, requiredSubstrings)
// result === true
const str = 'abcde'
const requiredSubstrings = ['a', 'b', 'f']
const result = hasRequiredSubstrings(str, requiredSubstrings)
// result === false
const str = 'abcde'
const requiredSubstrings = ['a', 'b', 'c']
const result = hasRequiredSubstrings(str, requiredSubstrings)
// result === true
const str = 'a man a plan a canal'
const requiredSubstrings = ['man', 'plan', 'canal']
const result = hasRequiredSubstrings(str, requiredSubstrings)
// result === true

Options

allowLastSubstringToBleed

The allowLastSubstringToBleed option is false by default. It it used when you want to allow the last substring to be incomplete if the string is too short. In the following example, the last substring canal starts at the correct index, but remains incomplete since the string ends. Normally this would return false. With allowLastSubstringToBleed set to true, it returns true.

const str = 'a man a plan a c'
const requiredSubstrings = ['man', 'plan', 'canal']
const allowLastSubstringToBleed = true
const result = hasRequiredSubstrings(str, requiredSubstrings, allowLastSubstringToBleed)
// result === true
options style

For style compatibility with related packages like has_required_substrings_after_sums, it is possible to set allowLastSubstringToBleed using an options style.

const str = 'a man a plan a c'
const requiredSubstrings = ['man', 'plan', 'canal']
const allowLastSubstringToBleed = true
const result = hasRequiredSubstrings(str, requiredSubstrings, {
  allowLastSubstringToBleed: allowLastSubstringToBleed
})
// result === true
