I'd like to run a function whenever the current directory in eshell changes (like a eshell-chdir-hook, but that doesn't exist). How can I do this?

  • There are functions within eshell that detect things like a cd ... entry, which triggers an elisp function -- e.g., eshell/cd -- depending upon whether certain modules have been loaded. You could modify that function and attach your own hook, depending upon whether you use that particular module. I took over eshell completely by making one large custom library and I no longer use modules, but it shouldn't be difficult to track down if you need some further assistance. – lawlist Sep 1 '15 at 3:36
  • No idea whether there is an Emacs hook for this, but you could presumably use a (shell) alias to change directories, and have that alias invoke Emacs in batch mode to invoke some Emacs function. Not saying this is a great solution... – Drew Sep 1 '15 at 3:36

Well duh. The answer is to use eshell-directory-change-hook.

  • Yep, there it is at the bottom of eshell/cd – lawlist Sep 1 '15 at 4:01
  • @lawlist yup. :) Thanks for the tip. – PythonNut Sep 1 '15 at 4:28
