How to make a variable loaded from .dir-locals.el global?

I save the variable in .dir-locals.el like this:

  (add-dir-local-variable 'nil 'CurrentProjectStat CurrentProjectStat)
  (save-buffer)
  (kill-buffer)

When I upload a file with a given project, this variable is loaded only for this buffer, but I need it to be loaded globally. I use this variable in the form of widgets, this is a different buffer, and this variable is no longer there.

I do not know in which direction to look, overriding the variable does not help.

Tell me please how to make such a variable global?

Solution

  • For the sake of answering the question as stated:

    You can use the pseudo-variable eval to evaluate arbitrary code, and therefore set a non-local variable (assuming the variable is not already buffer-local), like so:

    ((nil . ((eval . (setq GLOBALVAR VALUE)))))

    I strongly doubt that this is actually what you want to do, however.
