How to normalise file path in Nim?

Question

The os.normalized_path outputs . instead of the full path.

import os
echo ".".normalized_path

Answer 1

That output is correct - it's "normalised" to the current directory, so it's ".", which is a valid path on *nix. If you want to get the full path, do it like this:

import os
echo ".".normalizedPath().absolutePath()

Answer 2

@Yardanico's answer is still the right one, but this got too long to leave as a comment.

normalizePath has no knowledge of the current working directory and operates on abstract paths, preserving whether the input is absolute or relative. what it does is:

• remove extra/trailing slashes: 'foo//bar/' => 'foo/bar'
• resolve double dots: 'foo/../bar' => 'bar', '../foo' => '../foo'
• remove initial './': './foo' => 'foo'

it does not:

• remove initial double dots in absolute paths, i.e. '/..' => '/..'
• convert path delimiters to the native os delimiter.
• handle os9's idiosyncratic updirs properly
