Reset all buffer variables to default in Emacs
Question
How do you clear local variable customizations in buffer? In other words, how do you reset all variables to default?
Use case
This may be useful in instances where you M-x customize-variable and want to force those changes to persist on an open buffer.
If I have edited a .c file with c-basic-offset set to 2, then M-x customize-variable and change it to 4, new files will have an offset of 4, but existing files will maintain an offset of 2.
Notes
Using spacemacs.
1 answer
M-x kill-local-variable RET c-basic-offset seems to work, but only temporarily. If I save, and close Emacs, and revisit the file, the changes do not persist.
I that in an affected directory, each file must be visited and a permanent version of this must be performed. Not ideal.
