Nim2 /

removePrefix, removeSuffix

See also std/strutils

Python also has these two string methods. However, in Python, they return a new string object. In Nim, they modify the string in-place. If you want a Python-like behaviour, you can do that with a custom function.

removePrefix()

removePrefix()
s = "https://python.org"

print(s.removeprefix("https://"))  # python.org

print(s.removeprefix("ftp://"))  # https://python.org
import std/strutils

var s = "https://python.org"  # var, can be modified

s.removePrefix("https://")  # change in-place

echo s  # python.org ; `s` has changed!

# ---

func withoutPrefix*(s, prefix: string): string =
  ## Remove the given prefix. Returns a new string.
  result = s
  result.removePrefix(prefix)

let url  = "https://python.org"  # let, immutable

echo url.withoutPrefix("https://")  # python.org

echo url  # https://python.org ; original string

removeSuffix()

Can be done similarly to removePrefix() .
