(emacs) "Selecting deleted buffer" after *hie* buffer killed

[mgsloan]

If you use M-x kill-buffer on the *hie* buffer, subsequent commands error out with "Selecting deleted buffer". This is due to a use of with-current-buffer (hie-buffer). Maybe defining a utility like with-hie-buffer would be good, which also ensures that the buffer is initialized.

I seem unable to reproduce this. I am doing the following

1. Open a Haskell file
2. Ensure hie-mode is running and the *hie* buffer is available
3. Switch to *hie* buffer
4. Call M-x kill-buffer
5. Within my Haskell file, try calling M-x hie-base-plugins

I receive the following message

Process Haskell IDE Engine not running

If this is still an issue, would you be able to provide me with the exact steps you use to get this message?

Should the hie process be started if you call a function when it is not started?

@ankhers The buffers got refactored since @mgsloan opened that issue, but the general problem still exists.
Here’s an example:

1. Open a haskell file.
2. M-x hie-mode
3. M-x hie-eg2-sayHello
4. Kill the *hie-log* buffer
5. M-x hie-eg2-sayHello
   In this case the error is in hie-log but from a quick look almost all cases where we use with-current-buffer suffer from that problem although it might be hard to reproduce it in some cases. We already have a with-hie-refactor-buffer macro so just adding macros for the other buffers and using them should be enough.
