# This file is a minimal gn format vim-integration. To install:
|
|
# - Change 'binary' if gn is not on the path (see below).
|
|
# - Add to your .vimrc:
|
|
#
|
|
# map <F1> :pyf <path-to-this-file>/gn-format.py<CR>
|
|
#
|
|

|
|
# be used. It operates on the current, potentially unsaved buffer and does not
|
|
# create or save any files. To revert a formatting, just undo.
