However, the last block argument is always the path to the temporary directory.

Examples:

BioDSL::TmpDir.create do |dir|
  puts dir
    # => "<tmp_dir>"
end
BioDSL::TmpDir.create("foo", "bar") do |foo, bar, dir|
  puts foo
    # => "<tmp_dir>/foo"
  puts bar
    # => "<tmp_dir>/foo"
  puts dir
    # => "<tmp_dir>"
end

Parameters:

  • files (Array) —

    List of file names.
