Auto-format Nomsu code. Usage:
|
|
nomsu -t format [-i] file1 file2...
|
|
|
|
If the "-i" flag is used, the file will be edited in-place.
|
|
If the "-q" flag is used and an error occurs, the original file will be printed.
|
|
If no files are passed in, this will read from stdin.
|
|
|
|
use "lib/os"
