" asmfmt.vim: Vim command to format Go asm files with asmfmt
|
|
" (github.com/klauspost/asmfmt).
|
|
"
|
|
" This filetype plugin adds new commands for asm buffers:
|
|
"
|
|
" :Fmt
|
|
"
|
|
" Filter the current asm buffer through asmfmt.
|
|
" It tries to preserve cursor position and avoids
|
|
" replacing the buffer with stderr output.
|
|
"
|
|
" Options:
|
|
"
|
|
" g:go_asmfmt_autosave [default=0]
|
|
"
|
|
" Flag to automatically call :Fmt when file is saved.
