Overview

The replace() method is used to make changes to the content of a sequence so as to get our desired output.

The replace() method is part of Euphoria’s core library. This method will slice a target sequence starting from an indicated start_point to another end_point and replace the sliced section with another set of replace_with values. This will produce the transformed sequence, which has the new value added to it.

Unlike the match_replace() method, which looks for a match to replace, the replace() method won’t look for a match. Rather, it replaces whatever is in the indicated position and replaces it with whatever is available.

Syntax

replace(target,replace_with,start_point,endpoint)

Parameters

  • target: This is a required parameter. It is a sequence that will be sliced, and the sliced portion will be replaced with a value.

  • replace_with: This is also a required parameter. It is an object data type that will be used to replace the slice portion in the target.

  • start_point: This is an integer that indicates the index position in the target where the slicing will begin. It is required as well.

  • endpoint: This integer parameter, if omitted, will be assumed by the parser to be the same as the start_point, therefore, causing only a single value to be replaced in the sequence. This parameter indicates where the slice is to end.

Return value

It returns a sequence that contains the target with the items in the start_point and end_point slice removed and replaced by the replace_with value.

Example

--declare variables
sequence target = "This is the Edpresso system for byte sized shots"
object replace_with = ", HOME OF"
integer start_point = 21
integer end_point = 31
--replace the indicated slice
sequence output = replace(target,replace_with,start_point,end_point)
printf(1,"%s",{output})
Example of replace() method

Explanation

  • Lines 3–6: We declare the variables that will be used throughout the code.
  • Line 9: We use the replace() method to do the slicing and replacement.
  • Line 10: We print the output from the method to the screen.
