I have enable smart-tab mode as global minor mode by
(global-smart-tab-mode 1)
and want to disable it in eshell-mode,
(add-hook 'eshell-mode-hook
(lambda ()
(smart-tab-mode -1)))
but It seems not work and I'm sure this hook have been executed.
If I manually run (smart-tab-mode -1)
in eshell, It is OK.
I don't know why, could someone help me, thanks in advance!
