Topic: Argument order for basic-cli file writing functions

view this post on Zulip Isaac Van Doren (Nov 17 2024 at 18:54):

There have been several times where I've tried to write something like this 

myFileContent |> File.writeBytes! "/some/path"

and been very surprised that I actually needed to write this

 File.writeBytes! "/some/path" myFileContent

In the File module my initial assumption is that the file content is the important data structure that is the first argument to the functions, not the file path. I frequently want to build up the file content in a pipeline, but never the path, so it seems very unergonomic.

Because of this, I think we should change the file writing functions to accept the file content as the first argument. Thoughts?

Absolutely a good idea, I've noticed the same thing
