Instance Method Details

#find(args, mode) ⇒ Array

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Generate a list of target files by expanding globbing patterns (if any). If args is empty, recursively find all Ruby source files under the current directory

Returns:

  • (Array) —

    array of file paths

  files = []

  args.uniq.each do |arg|
    files += if File.directory?(arg)

end

#find_files(base_dir, flags) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Search for files recursively starting at the given base directory using the given flags that determine how the match is made. Excluded files will be removed later by the caller, but as an optimization find_files removes the top level directories that are excluded in configuration in the normal way (dir/*/).

#target_files_in_dir(base_dir = Dir.pwd) ⇒ Array

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Finds all Ruby source files under the current or other supplied directory. A Ruby source file is defined as a file with the ‘.rb` extension or a file with no extension that has a ruby shebang line as its first line. It is possible to specify includes and excludes using the config file, so you can include other Ruby files like Rakefiles and gemspecs.

Parameters:

  • base_dir (defaults to: Dir.pwd) —

    Root directory under which to search for ruby source files

Returns:

  • (Array) —

    Array of filenames
