addlicense

This project adds the given license to all source file in a given directory. The tool will try to avoid source files that already has a header. This project can be used as a CLI as well as a library imported to a go script.

Inspiration

The initial inspriation is from this repo from Google. While the google addlicense project is good, but there are some additional requirements I needed.

1. I want the code to be a importable library in addition to just a tool. In this way, I can import this to write my own customized scripts.
2. Template is an overkill for most people. Most of the time, I just want to attach a license to all my files. If I am making changes to the license, such as updating the year, I will just update a single license file. So I simplified the codebase.

Build

make

Test

make test

Usage

This project can be consumed either as a CLI or as a lib.

CLI

To install:

go get -u github.com/unkies/addlicense/cmd/addlicense

Note: You may need to add you $GOPATH/bin to your $PATH.

To uninstall:

go clean -i github.com/unkies/addlicense/cmd/addlicense

To use, first create a file with the license header you want to add. See ./LICENSE as an example of the MIT license.

addlicense add --license <license file> --ignore <if any ignore patterns> <root of source code>

For usage, consult addlicense -h and make dogfood_add as an example of adding ./LICENSE to this repo. For example to remove license headers, see make dogfood_remove.

Lib

Follow the reference here

import "github.com/unkies/addlicense/libaddlicense"

// Read the license file
license, _ := ioutil.ReadFile("./LICENSE")

// Add licenses to a project root, but ignore certain files
srcRoot := "."
ignore := []string{"testdata"}
_ := libaddlicense.AddLicense(srcRoot, license, ignore)
// Or no need to ignore
_ := libaddlicense.AddLicense(srcRoot, license, []string{})

// To add a license to a file
path := "somepath/somefile.go"
_ := libaddlicense.AddLicense(path, license, []string{})
