@spec each(
  %{required(String.t() | [String.t()]) => String.t()},
  String.t(),
  (... -> any())
) :: :ok

Open a file for write for all key/value pairs, interleaves the file name with the key and calls the given function with file, content and filename.

Uses interleave/2 to get the base filename and the given keys together to one nice file name, then creates these files and calls the function with the file and the content from the given map so that data can be written to the file.

If a directory is specified, it creates the directory.

Expects:

  • names_to_content - a map from input name to contents that should go into the corresponding file
  • filename - the base file name as desired by the user
  • function - a function that is then called for every file with the associated file content from the map, defaults to just writing the file content via IO.write/2 and printing where it put the file.

Examples

# Just writes the contents to a file
Benchee.Utility.FileCreation.each(%{"My Input" => "_awesome html content_"},
  "my.html",
  fn(file, content) -> IO.write(file, content) end)

interleave(filename, names)

View Source
@spec interleave(String.t(), String.t() | [String.t()]) :: String.t()

Gets file name/path, the input name and others together.

Takes a list of values to interleave or just a single value. Handles the special no_input key to do no work at all.

Examples

iex> interleave("abc.csv", "hello")
"abc_hello.csv"

iex> interleave("abc.csv", "Big Input")
"abc_big_input.csv"

iex> interleave("abc.csv", "String.length/1")
"abc_string_length_1.csv"

iex> interleave("bench/abc.csv", "Big Input")
"bench/abc_big_input.csv"

iex> interleave("bench/abc.csv",
...>   ["Big Input"])
"bench/abc_big_input.csv"

iex> interleave("abc.csv", [])
"abc.csv"

iex> interleave("bench/abc.csv",
...>   ["Big Input", "Comparison"])
"bench/abc_big_input_comparison.csv"

iex> interleave("bench/A B C.csv",
...>   ["Big Input", "Comparison"])
"bench/A B C_big_input_comparison.csv"

iex> interleave("bench/abc.csv",
...>   ["Big Input", "Comparison", "great Stuff"])
"bench/abc_big_input_comparison_great_stuff.csv"

iex> marker = Benchee.Benchmark.no_input()
iex> interleave("abc.csv", marker)
"abc.csv"
iex> interleave("abc.csv", [marker])
"abc.csv"
iex> interleave("abc.csv",
...>   [marker, "Comparison"])
"abc_comparison.csv"
iex> interleave("abc.csv",
...>   ["Something cool", marker, "Comparison"])
"abc_something_cool_comparison.csv"
