Examples

If you are running crlfmt on the http://github.com/cockroachdb/cockroach codebase, you can use the following command to reformat all files in the current directory, ignoring generated code files:

$ crlfmt -w -ignore '\.(pb(\.gw)?)|(\.[eo]g)\.go|/testdata/|^sql/parser/sql\.go$|_generated(_test)?\.go$' .
