Path

Additional Language Notes

1. path is technically a "syntax shape" rather than a full "type". It is used for annotating strings that should be treated as a path to a filename or directory. ~ and . characters in the string will automatically be expanded treated as a path.

   Example:

   def show_difference [
    p: path
    s: string
   ] {
    print $"The path is expanded: ($p)"
    print $"The string is not: ($s)"
   }
   
   # Results
   cd ~/testing
   show_difference . .
   # => The path is expanded: /home/username/testing
   # => The string is not: .
   show_difference ~ ~
   # => The path is expanded: /home/username
   # => The string is not: ~
   
   # Multi-level directory traversal is also supported
   show_difference ... ...
   # => The path is expanded: /home/
   # => The string is not: ...

2. The built-in syntax highlighting also treats strings and paths differently. Notice when typing the commands in the above example that, depending on your color configuration, the first and second argument will have different colorization.

Casts

There is no into path command, but several commands can be used to convert to and from a path:

• path expand
• path join
• path parse

Common commands that can work with path

• path (subcommands)
  • See: help path for a full list
• Most filesystem commands (e.g., ls, rm)
  • See: help commands | where category == filesystem
