write licenses to stdout
Write a license to standard output given its SPDX ID. A name for the copyright holder can optionally be provided for licenses where it is included. If the provided ID isn't found, similar ones will be suggested. Licenses are all compiled into the binary.
- Simple
- Licenses are taken directly from SPDX, no slightly edited templates
- Single binary, licenses are included into it at compile time
WITH
exception expressions support- Ability to skip the copyright notice, which is allowed by the Berne convention
- Adding new licenses just requires editing a JSON file
I just got tired of losing time looking for license files for my new projects.
Here are a couple usage examples to get a general idea of how it all works. For detailed usage, just pass the --help
flag.
Write the MIT license with a copyright notice to LICENSE
:
$ licensor MIT "Raphaël Thériault" > LICENSE
Write the Apache 2.0 license with the LLVM exception to LICENSE
, skipping optional parts:
$ licensor "Apache-2.0 WITH LLVM-exception" --skip-optional > LICENSE
Print the BSD 3 Clause license without a copyright notice:
$ licensor BSD-3-Clause
List available licenses
$ licensor --licenses
There are a few installation option available.
You are welcome to distribute this software on other platforms, don't hesitate to open a PR to update this section if you do so!
Pre-compiled binaries of licensor
can be downloaded from the release page.
$ brew install licensor
$ cargo install licensor
See list.
Contributors are welcome. If you see anything that could be fixed/improved or have a new feature idea, just open an issue or a PR!
However, try to keep the main CLI as simple and light as possible. Features such as adding licenses/exceptions at runtime or validating licenses are not planned and will not be added.
If you'd like a license to be added to the list, you can either open an issue for it or add it yourself, which is fairly easy.
To add a license, just add it to resources/licenses.json
following the schema provided in resources/licenses-schema.json
. To apply the changes to the main CLI, you'll also need to run both cargo run -p licensor_fetch
and cargo run -p licensor_codegen
, in that order. To get the information you need, just refer to the SPDX License List.
The same goes for exceptions.
First, licenses and exceptions specified in the resources files are parsed from the SPDX License List, then gzipped, using the licensor_fetch subcrate. Then the codegen.rs file is automatically generated based on the parsed licenses, using the licensor_codegen subcrate, and included in the CLI.
Finally, the main CLI is built on its own, which makes the build time relatively fast for end users and only requires dependencies of the main CLI and not ones required by helper subcrates.
Thanks to the amazing people on the /r/rust subreddit who provided great feedback and hints, and showed way more enthusiasm than initially expected.
