Temporary Files And Directories in Wolfram Language
Here’s the translation of the Go code to Wolfram Language, formatted in Markdown for Hugo:
(* Throughout program execution, we often want to create
data that isn't needed after the program exits.
Temporary files and directories are useful for this
purpose since they don't pollute the file system over
time. *)
(* The easiest way to create a temporary file is by
using CreateFile. We provide $TemporaryDirectory as
the first argument, so CreateFile will create the file
in the default temporary location for our OS. *)
tempFile = CreateFile[FileNameJoin[{$TemporaryDirectory, "sample_" <> ToString[RandomInteger[{1000, 9999}]] <> ".tmp"}]];
(* Display the name of the temporary file. *)
Print["Temp file name: ", tempFile];
(* Clean up the file after we're done. *)
DeleteFile[tempFile];
(* We can write some data to the file. *)
BinaryWrite[tempFile, {1, 2, 3, 4}];
Close[tempFile];
(* If we intend to write many temporary files, we may
prefer to create a temporary directory. *)
tempDir = CreateDirectory[FileNameJoin[{$TemporaryDirectory, "sampledir_" <> ToString[RandomInteger[{1000, 9999}]]}]];
Print["Temp dir name: ", tempDir];
(* Clean up the directory after we're done. *)
DeleteDirectory[tempDir, DeleteContents -> True];
(* Now we can synthesize temporary file names by
prefixing them with our temporary directory. *)
tempFileName = FileNameJoin[{tempDir, "file1"}];
BinaryWrite[tempFileName, {1, 2}];
Close[tempFileName];In Wolfram Language, we use built-in functions to handle temporary files and directories. Here’s a breakdown of the translation:
We use
CreateFileto create a temporary file. The file name is generated usingRandomIntegerto ensure uniqueness.The
Printfunction is used to display the temporary file name.DeleteFileis used to remove the temporary file.BinaryWriteis used to write data to the file.For creating a temporary directory, we use
CreateDirectory.DeleteDirectoryis used to remove the temporary directory and its contents.FileNameJoinis used to create file paths in a platform-independent manner.
Note that Wolfram Language handles file closing automatically in most cases, but it’s good practice to explicitly Close files after writing.
To run this code, you would typically save it in a .nb (Notebook) file and execute it in the Wolfram Language environment or Mathematica.
