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.
addlicense requires go 1.16 or later.
go install github.com/google/addlicense@latest
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
-ignore file patterns to ignore, for example: -ignore **/*.go -ignore vendor/**
The pattern argument can be provided multiple times, and may also refer to single files. Directories are processed recursively.
For example, to run addlicense across everything in the current directory and all subdirectories:
addlicense .
The -ignore
flag can use any pattern supported by
doublestar.
The simplest way to get the addlicense docker image is to pull from GitHub Container Registry:
docker pull ghcr.io/google/addlicense:latest
Alternately, you can build it from source yourself:
docker build -t ghcr.io/google/addlicense .
Once you have the image, you can test that it works by running:
docker run -it ghcr.io/google/addlicense -h
Finally, to run it, mount the directory you want to scan to /src
and pass the
appropriate addlicense flags:
docker run -it -v ${PWD}:/src ghcr.io/google/addlicense -c "Google LLC" *.go
