-diff Display only diffs between the formatted source and the original source.
-l List files whose formatting differs from vfmt.
-w Write result to (source) file(s) instead of to stdout.
-2 Use the new V parser/vfmt. NB: this is EXPERIMENTAL for now.
The new vfmt is much faster and more forgiving.
It also may EAT some of your code for now.
Please be careful, and make frequent BACKUPS, when running with -vfmt2 .
-debug Print the kinds of encountered AST statements/expressions on stderr.
NB: vfmt after 2020/04/01 is based on the new AST compiler code, and
thus is much faster, and more flexible than before.
It may also EAT some of your code for now, so please be careful, and
make frequent BACKUPS.
