Post-Processing Scripts

JavaScript I/O
input will be a global variable accessible in the JS context. The structure of input is the following:
interface Input = {
  text: string,
  textbox: TextBox
}
where
interface TextBox {
  // TopLeft.x, TopLeft.y, TopRight.x, TopRight.y, BottomRight.x, BottomRight.y, BottomLeft.x, BottomLeft.y
  vertices: number[], 
  orientation: "Up" | "Left" | "Right" | "Down",
  lines: {
      words: Word[]
  }
}
​
interface Word {
  // TopLeft.x, TopLeft.y, TopRight.x, TopRight.y, BottomRight.x, BottomRight.y, BottomLeft.x, BottomLeft.y
  vertices: number[],
  value: string, // text in the word
  symbols: Symbol[]
}
​
interface Symbol {
  // TopLeft.x, TopLeft.y, TopRight.x, TopRight.y, BottomRight.x, BottomRight.y, BottomLeft.x, BottomLeft.y
  vertices: number[],
  value: string // character in the symbol
}
The script is expected to write the output to the result value in the global scope. If not, an exception will be raised. What is assigned to resultwill be in the content field of the output response.

Parameters:
pattern (string): Will be used to search target text
text (string): The target text where search will be conducted upon
options (FuzzySearchOptions): Optional parameters
Options for configuring the fuzzy search behaviour
max_subs (number)Optional
Maximum subsitutions between the pattern and return string
max_insert (number) Optional
Amount of character that can be skipped in the pattern
max_delete (number) Optional
Amount of character that can be skipped in the return string
max_l_dist (number) Optional
Maximum Levenshtein distance allowed between the pattern and return string
Return Value:
matches (Match[]): Array of matches
start (number): Start position of the match
end (number): End position of the match
dist (number): Levenshtein distance between the matched part and the pattern
matched (string): matched part
edit_distance(string1, string2)
Returns the distance between two strings
