# SPDX CLI
A command-line wrapper to the SPDX license list.
## Installation
This program is an Elixir escript, so you will need to [install Elixir](https://elixir-lang.org/install.html) first.
Once Elixir is installed, you can install the escript using `mix`:
```sh
mix escript.install hex spdx_cli
```
This will install the script to `~/.mix/escripts`, which you should add to your `PATH`.
## Usage
Use `spdx` to download license texts.
You will need to know the SPDX identifier for your license.
```
$ spdx MIT
MIT License
Copyright (c) <year> <copyright holders>
THE SOFTWARE IS PROVIDED "AS IS"...
```
Pipe this into a file, and boom, you've got your license!
```sh
spdx MIT > LICENSE
```
You can also use `spdx ls` to list all licenses in the database, possibly for piping into `grep`.
```sh
spdx ls | grep 'Creative Commmons' | wc -l
49
```
## Other projects like this
Check out the Free Software Foundation Europe's [REUSE helper tool](https://github.com/fsfe/reuse-tool).
It can lint your project against the REUSE specification,
which makes it easier for other people to reuse your work.
It can also download licenses, and add licensing headers to your source files.
## Roadmap
- ~Fetch license text~
- ~Fetch other license fields (name, header)~
- Search licenses by name or ID
Please suggest more cool stuff I can do with this!
