Auto-reloading sandwich TUI workflow?

[ryantm]

Hi.

It would be nice to reload my sandwich TUI when either my tests or code change. Does anyone have a good solution for this?

I tried:

$ find *.hs | entr -r bash -c 'cabal v2-run test -- --tui'
Up to date
Some formatters failed: '[getTerminalAttributes: illegal operation (Inappropriate ioctl for device)]'
1 runs succeeded out of 1 repeats

It works with normal entr if I manually exit out of the tui after editing the files.

Hmm, I notice that find -name "*.hs" | entr -r htop doesn't work either. I suspect entr isn't hooking the subprocess up to a proper pty.

Could you explain how you got that to work?

I've daydreamed about making a Sandwich reloader that runs a GHCi subprocess like how ghcid does, and magically reloads code when files change...

Oh, I see that it launches TUI apps successfully without the -r flag. This does seem like a problem with entr.

BTW, I should mention another solution that came up on #98:

I think this will be the "answer" for now, since the amount of engineering effort to do this without something like watchexec is still prohibitive.
