How to get filename without extension from file path in Ruby

How to Get Filename Without Extension from File Path in Ruby 💎

So you want to extract the filename without the extension from a file path in Ruby? 🤔 No worries, we've got you covered!

Let's say you have a file path like this: "C:\projects\blah.dll" and all you want is the pure and simple "blah". Here are some easy solutions to get that filename without breaking a sweat. 💪

Solution 1: Splitting the Path

One way to extract the filename without the extension is by utilizing the File.basename method along with File.extname method. Here's how you can do it:

file_path = "C:\\projects\\blah.dll"
filename_with_extension = File.basename(file_path)
filename_without_extension = File.basename(file_path, ".*")

In this code snippet, the File.basename(file_path) will provide you the filename with the extension, which in our example would be "blah.dll". However, we don't want the extension, so we pass ".*" as the second argument to File.basename to strip the extension and get "blah".

Solution 2: Using Regex Magic

If you prefer a more flexible approach, you can unleash the power of regular expressions to capture the desired filename. Take a look at this code snippet:

file_path = "C:\\projects\\blah.dll"
filename_without_extension = file_path.match(/\\([^\\.]*)\.[^\\.]*$/)[1]

In this case, we utilize a regex pattern: /(\\([^\\.]*)\.[^\\.]*$)/. This pattern captures the filename without the extension by looking for the last backslash \ and then matching any characters that are not a backslash or a period.

Solution 3: Pathname Magic ✨

Another great way to accomplish this task is by using the Pathname class from the Ruby Pathname library. Check out this code snippet:

require 'pathname'

file_path = "C:\\projects\\blah.dll"
pathname = Pathname.new(file_path)
filename_without_extension = pathname.basename(".*")

By utilizing Pathname.basename and passing ".*" as the argument, we conveniently retrieve the filename without the extension.

Choose Your Path 🛤️

Now you have multiple paths to choose from! Select the solution that fits your coding style and preference. ✅

If you want to deep dive into the officially documented methods, don't hesitate to visit the Ruby documentation for File and Pathname.

Remember, the possibilities in Ruby are endless, and extracting filenames without extensions can be as easy as a single line of code! 😄
