For my function, that I have created, I'm looking for an Eshell mode hook.

I'm aware of the following hook:

(add-hook 'eshell-mode-hook 'my-function-for-eshell).

But what when I'm in a other buffer and want to switch back to the existing buffer with Eshell mode, I want to run that function? But I found all the hooks only will be triggered, when you create a new buffer with an Eshell mode.

To be clear, I run Evil normal mode when I do switch buffers with a keybinding in normal mode. The my-function-for-eshell brings me back in Evil insert mode, when I go back to Eshell.

There is no hook specifically for switching buffers, but you can use the buffer-list-update-hook. Switching buffers re-orders the buffer list and triggers this hook, so you could use that to run a command that checks the major-mode of the current buffer and takes some action if it is eshell.

  • It might add a large overhead because Eshell is a tiny part of my workflow, and I switch buffers a lot. But better than nothing, thanks for that!

    How about your own command to switch to your eshell buffer and run whatever additional commands you need?

  • Not possible, because when I split my window, my Eshell window lies adjacent. I have a default keybinding where I can navigate to all windows. When I want to Eshell window, I need another keybinding then in order to call my own command. But thanks for the suggestion, a good idea anyway.
