Reading commands from a file / improved Node.js repl integration

[jq170727]

I've been using bandersnatch to interactively test libraries I'm developing.
I'm finding it would be helpful to have a consistent way in the repl to read and evaluate commands from a file.
This would allow me to easily reuse sequences of commands.

The Node.js repl provides .save and .load but I don't think they work in bandersnatch.
For example if I start my cli, run some commands and then enter .save bar
I'll see a message Session saved to: bar but only an empty "bar" file will be created.

Similarly if I create a file "foo" containing some commands and run .load foo it looks like
the commands aren't parsed properly. E.g.

> .load foo
init
signin user1 password1
signout

> (press enter)
Error: Unknown arguments: init
signin, user1, password1
signout
> 

Note my cli is suppressing the complete backtrace for the "Unknown arguments" error so you don't see it here.
The commands in this example work fine if entered line at a time. Also curious that the error report includes
commas in between the arguments of the second command.

From this I conclude some part of the Node.js repl is there but not fully integrated in bandersnatch.
It would be nice if the Node.js .save/.load commands worked as they do in Node.js or if similar functionality
was available in another form.

I suspect this functionality is currently broken because of some enquirer interop workarounds, see e.g. https://github.com/hongaar/bandersnatch/blob/main/src/repl.ts#L28

Can you try to comment out lines 30 and 124 of this file, and see if it makes a difference?

Thank you. I tried your suggestion.
After commenting out the corresponding lines in lib/esm/repl.js with pnpm patch
(For reference here's the change I made: [email protected] )

I found the .save function now writes the commands to the file as expected. 🎉

But the .load behavior is unchanged - the saved commands seem to be parsed incorrectly.
