  • # 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`.

Reset all buffer variables to default
# 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`.
