license

license is a command line tool to create LICENSE files.

It provides good defaults for name and year on license (customizable if needed), and it supports all license types listed on the GitHub Licenses API and a few more. The license templates used by this program were copied from the GitHub Licenses API, when available.

Usage

Print license

To print a license to stdout, run the license command followed by the license name:

$ license mit

Save to file

Use the -o flag to save the license to a file, or use your shell's redirection operator:

$ license -o LICENSE.txt mit
$ license mit > LICENSE.txt

Customize name and year

$ license -year 2013 -name "Alice L" isc

The current year is used if -year is omitted.

To determine the name on the license, the following are used in this order:

- command line flags: -name, -n
- environment variable: LICENSE_FULL_NAME
- gitconfig and hgconfig
- "os/user".Current()
- empty string

If you have your name set in $HOME/.gitconfig, you can almost always omit the -name flag.
