Python has an excellent module for path handling called pathlib (see blog post). What is its Nim equivalent?

pathlib in Nim

from pathlib import Path

def main():
p = Path("/usr/lib/python2.5/gopherlib.py")
# 1
print(p.parent) # /usr/lib/python2.5
# 2
print(p.name) # gopherlib.py
# 3
print(p.suffix) # .py
# 4
print(p.stem) # gopherlib
# 5
q = Path("/trash", "xxx", "movie.mp4")
print(q) # /trash/xxx/movie.mp4
# 6
print(Path.home()) # /home/jabba

import std/os
import std/strutils

func rstrip*(s: string, chars: string): string =
var bs: set[char] = {}
for c in chars:
bs = bs + {c}
s.strip(leading=false, trailing=true, chars=bs)

proc main() =
let p = "/usr/lib/python2.5/gopherlib.py"

# 1 - parent directory
echo p.parentDir() # /usr/lib/python2.5

# 2 - file name (with extension)
echo p.extractFilename() # gopherlib.py

# 3 - suffix/extension (including dot)
echo p.splitFile().ext # .py

# 4 - stem (name without extension)
echo p.splitFile().name # gopherlib

# 5 - join paths
let q = "/trash" / "xxx" / "movie.mp4"
echo q # /trash/xxx/movie.mp4

# 6 - home directory
echo getHomeDir().rstrip("/") # /home/jabba

main()
