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.

This is a forked and slightly evolved variant of google/addlicense

Install as a Go program

go get -u github.com/nokia/addlicense

Usage as a Go program

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")
-s silent mode: do not log anything to the console
-y year (defaults to current year)
-check check only mode: verify presence of license headers and exit with non-zero code if missing
-config yaml config file: see examples/config.yml

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

For example to check a project for license headers:

addlicense -check /path/to/my/project

Run as a container

Pull from dockerhub

docker pull nokia/addlicense-nokia

The image can now be run using the run_addlicense script:

./run_addlicense.sh "addlicense-options"

Where the addlicense-options are the options for addlicense (in quotes).

The current working directory is used as the starting point to run addlicense.

To use with the default configuration and BSD 3 Clause copyright texts use:

./run_addlicense.sh "-f /copyright-texts/bsd-3-clause"

or

docker run -e OPTIONS="-f /copyright-texts/bsd-3-clause" --rm -it -v $(pwd):/myapp nokia/addlicense-nokia:latest

Configuration

Paths to be ignored by addlicense can be configured in a yaml config file and passed to addlicense using the -config option. Patterns that determine whether a file already has a license and file extension comment commenting formats can also be configured there.

For more concrete examples, see the example config.yml.

Ignored paths

The ignored paths can be configured using glob patterns. Example of excluding everything inside the tests and docs folders:

ignorePaths:
  - 'tests/**'
  - 'docs/**'

Comment patterns

Example of configuring comment patterns for some file extensions:

fileExtensions:
  - extensions: ['.js', '.mjs', '.cjs', '.jsx', '.tsx', '.css', '.tf', '.ts']
    top: '/**'
    mid: ' * '
    bot: '*/'

The "top" value speciefies how to begin the comment, the "mid" value how to continue the comment on new lines and the "bot" how to close the comment.

Has-license patterns

Patterns that determine whether a file already has a license can be configured like this:

hasLicensePatterns: 
  - 'copyright'
  - 'license'
