Ruby Directory Glob Recursive on Absolute Path

I'm trying to get the Dir.glob of an absolute path: This is my directory structure: When I run on the directory I only get the files in the root of the directory: But no entries for the app subdirectory.

I'm trying to get the Dir.glob of an absolute path:

path = "/Users/ken/templates" scaffold = Dir.glob("#{path}/*.erb", File::FNM_DOTMATCH) p scaffold.inspect

This is my directory structure:

/Users/ken/templates/test.erb /Users/ken/templates/test2.erb /Users/ken/templates/app/one.erb /Users/ken/templates/app/two.erb

When I run on the directory I only get the files in the root of the directory:

"[\"/Users/ken/farmstead/test.erb\", \"/Users/ken/farmstead/test2.erb\"]"

But no entries for the app subdirectory.

How do I get the Glob to go recursive on the absolute path?

To get into subdirectories, one needs to instruct Dir#glob to get into subdirectories:

# ⇓⇓⇓ scaffold = Dir.glob("#{path}/**/*.erb", File::FNM_DOTMATCH)

Quote from the documentation I linked:

**
    Matches directories recursively.

A cleaner way to tell glob about the absolute directory is to use the base parameter like so:

Dir.glob("**/*.erb", base: path)
