Temporary files

Hello everyone,

I would like to use a temporary file for a project and I didn't find an existing method.

I'm asking my self if it's a better idea to use ffi or OSSubProcess (or something already build for it) to build a method able to create this tmp file.

Someone could help me please?

PS : Should it be a good idea to add this method directly in Pharo ?

Hi,

For temporary files you can create a new file in memory via `FileSystem
memory` so you do not pollute your file system and the file will be
deleted later since the memory is volatile.

`file := FileSystem memory / 'tmp.txt'.
file ensureCreateFile.
file writeStreamDo: [ :s | s nextPutAll: 'Hello World' ].`
