commit e0bccb1114be0e03e8a507076e6ad5e9b9f6ee8b
Author: Marcio Giaxa <i...@mgxm.me>
Commit: Marcio Giaxa <i...@mgxm.me>
add zig-format-buffer command
By default the value of `zig-format-on-save` is set to `t`, meaning
that the code is automatically formatted before saves, to disable it,
you can set it to nil.
Besides that, you can toggle the behavior on certain buffers using
`M-x zig-toggle-format-on-save`.
* adds defcustom:
- zig-format-on-save
- zig-zig-bin
* adds defun:
- zig-toggle-format-on-save
- zig-format-buffer
