addlicense

The program ensures source code files have copyright license headers by scanning directory patterns recursively.

It modifies all source files in place and avoids adding a license header to any file that already has one.

install

go get -u github.com/google/addlicense

usage

addlicense [flags] pattern [pattern ...]

-c copyright holder (defaults to "Google LLC")
-f custom license file (no default)
-l license type: apache, bsd, mit, mpl (defaults to "apache")
-y year (defaults to current year)
-check check only mode: verify presence of license headers and exit with non-zero code if missing

The pattern argument can be provided multiple times, and may also refer to single files.
