The problem is that the values are apparently assigned *after* the mode's hook is run, so they are either "ignored" when I visit the source file, or "considered" only when I actually modify it. Let me try to explain. In my Python sources, using Emacs python.el mode python-mode-hook, I usually enable both `whitespace-mode` to highlight lines longer than `fill-column` (I set `whitespace-line-column` to nil) and `flymake-python-pyflakes-load` to check their syntax with pyflakes. In a particular project I'm using Python 3, and I want to have a different `fill-column` to make my coworkers happy, so I created a top level `.dir-locals.el` file containing ((nil . ((fill-column . 75))) (python-mode . ((flymake-python-pyflakes-executable . "python3") (flymake-python-pyflakes-extra-arguments . ("-m" "pyflakes"))))) When I visit/create a Python source, its local settings are changed accordingly, but a) whitespace highlights lines longer than the *global* value of `fill-column`, not its local setting b) flymake shows syntax errors, because the "initial run" of pyflakes has been done with the standard settings, i.e. with its Python 2 variant To make effect a) disappear I must execute M-: (whitespace-color-on), so it "reinstall" its font-lock customization, while effect b) goes away as soon as I change the buffer, triggering a new execution of pyflakes. Is there some hook that I can use that runs *after* the major mode hooks *and* the local variables settings got applied, so that I can force whitespace refresh and trigger a flymake check? Thanks in advance for any hint, ciao, lele. -- nickname: Lele Gaifax | Quando vivrò di quello che ho pensato ieri real: Emanuele Gaifas | comincerò ad aver paura di chi mi copia. lele@metapensiero.it | -- Fortunato Depero, 1929.
