filesystem_access(path, action = :write) { |path| ... } click to toggle source

Rescues permissions errors raised by file system operations (ie. Errno:EACCESS) and raises more friendly errors instead.

@param path [String] the path that the action will be attempted to @param action [Symbol, to_s] the type of operation that will be

performed. For example: :write, :read, :exec

@yield path

@raise [Bundler::PermissionError] if Errno:EACCES is raised in the

given block

@example

filesystem_access("vendor/cache", :write) do
  FileUtils.mkdir_p("vendor/cache")
end
