Description
A drop-in replacement for the current Pathname class.
Prerequisites
- facade
- ffi (Windows only)
- test-unit (testing only)
Installation
gem install pathname2
Adding the Trusted Cert
gem cert --add <(curl -Ls https://raw.githubusercontent.com/djberg96/pathname2/main/certs/djberg96_pub.pem)
Synopsis
require 'pathname2'
# Unix
path1 = Pathname.new("/foo/bar/baz")
path2 = Pathname.new("../zap")
path1 + path2 # "/foo/bar/zap"
path1 / path2 # "/foo/bar/zap" (same as +)
path1.exists? # Does this path exist?
path1.dirname # "/foo/bar"
path1.to_a # ['foo','bar','baz']
# Windows
path1 = Pathname.new("C:/foo/bar/baz")
path2 = Pathname.new("../zap")
path1 + path2 # "C:\\foo\\bar\\zap"
path1.root # "C:\\"
path1.to_a # ['C:','foo','bar','baz']
Windows Notes
All forward slashes are converted to backslashes for Pathname objects.
Differences between Unix and Windows
If your pathname consists solely of ".", or "..", the return value for Pathname#clean will be different. On Win32, "\" is returned, while on Unix "." is returned. I consider this an extreme edge case and will not worry myself with it.
Differences between Pathname in the standard library and this version
- It is a subclass of String (and thus, mixes in Enumerable).
- It has sensical
to_a
androot
instance methods. - It works on Windows and Unix. The current implementation does not work with Windows path names very well, and not at all when it comes to UNC paths.
- The
Pathname#cleanpath
method works differently - it always returns a canonical pathname. In addition, there is no special consideration for symlinks (yet), though I'm not sure it warrants it. - The
Pathname#+
method auto cleans. - It uses a facade for all File and Dir methods, as well as most FileUtils methods.
-
Pathname#clean
works slightly differently. In the stdlib version,Pathname#clean("../a")
returns "../a". In this version, it returns "a". This affects other methods, such asPathname#relative_path_from
. - Accepts file urls and converts them to paths automatically, e.g. file:///foo%20bar/baz becomes '/foo/bar/baz'.
- Adds a Kernel level
pn
method as a shortcut. - Allows you to add paths together with the '/' operator.
Method Priority
Because there is some overlap in method names between File, Dir, and FileUtils, the priority is as follows:
- File
- Dir
- FileUtils
In other words, whichever of these defines a given method first is the method that is used by the pathname2 library.
Known Issues
On MS Windows, some methods may not work on pathnames greater than 260 characters because of internal function limitations.
Any issues you find should be reported on the project page at https://github.com/djberg96/pathname2
Future Plans
None at this time. Suggestions welcome.
