## Background

Copyright and licensing is difficult, especially when reusing software from
different projects that are released under various different licenses.
[REUSE](https://reuse.software) was started by the
[Free Software Foundation Europe](https://fsfe.org) (FSFE) to provide a set of
recommendations to make licensing your Free Software projects easier. Not only
do these recommendations make it easier for you to declare the licenses under
which your works are released, but they also make it easier for a computer to
understand how your project is licensed.

As a short summary, the recommendations are threefold:

1. Choose and provide licenses
2. Add copyright and licensing information to each file
3. Confirm REUSE compliance

You are recommended to read [our tutorial](https://reuse.software/tutorial) for
a step-by-step guide through these three steps. The
[FAQ](https://reuse.software/faq) covers basic questions about licensing,
copyright, and more complex use cases. Advanced users and integrators will find
the [full specification](https://reuse.software/spec) helpful.

This tool exists to facilitate the developer in complying with the above
recommendations.

There are [other tools](https://reuse.software/comparison) that have a lot more
features and functionality surrounding the analysis and inspection of copyright
and licenses in software projects. The REUSE helper tool, on the other hand, is
solely designed to be a simple tool to assist in compliance with the REUSE
recommendations.

## Example demo

In this screencast, we are going to follow the
[tutorial](https://reuse.software/tutorial), making the
[REUSE example repository](https://github.com/fsfe/reuse-example/) compliant.

## Install

### Installation via package managers

There are packages available for easy install on some operating systems. You are
welcome to help us package this tool for more distributions!

- Arch Linux: [reuse](https://archlinux.org/packages/community/any/reuse/)
- Debian: [reuse](https://packages.debian.org/search?keywords=reuse&exact=1)
- GNU Guix: [reuse](https://guix.gnu.org/packages/reuse-0.13.0/)
- Fedora: [reuse](https://apps.fedoraproject.org/packages/reuse)
- NixOS: [reuse](https://search.nixos.org/packages?channel=21.05&from=0&size=50&sort=relevance&type=packages&query=reuse)
- openSUSE: [reuse](https://software.opensuse.org/package/reuse)
- VoidLinux: [reuse](https://voidlinux.org/packages/?arch=x86_64&q=reuse)

An automatically generated list can be found at
[repology.org](https://repology.org/project/reuse/versions), without any
guarantee for completeness.

### Installation via pip

To install reuse, you need to have the following pieces of software on your
computer:

- Python 3.6+
- pip

You then only need to run the following command:

```bash
pip3 install --user reuse
```

After this, make sure that `~/.local/bin` is in your `$PATH`. On Windows, the
required path for your environment may look like
`%USERPROFILE%\AppData\Roaming\Python\Python39\Scripts`, depending on the Python
version you have installed.

To update reuse, run this command:

```bash
pip3 install --user --upgrade reuse
```

For full functionality, the following pieces of software are recommended:

- Git
- Mercurial 4.3+

### Installation from source

You can also install this tool from the source code, but we recommend the
methods above for easier and more stable updates. Please make sure the
requirements for the installation via pip are present on your machine.

```bash
python3 setup.py install
```

## Usage

First, read the [REUSE tutorial](https://reuse.software/tutorial/). In a
nutshell:

1. Put your licenses in the `LICENSES/` directory.
2. Add a comment header to each file that says
   `SPDX-License-Identifier: GPL-3.0-or-later`, and
   `SPDX-FileCopyrightText: $YEAR $NAME`. You can be flexible with the format,
   just make sure that the line starts with `SPDX-FileCopyrightText:`.
3. Verify your work using this tool.

Example of header:

```
# SPDX-FileCopyrightText: 2017 Free Software Foundation Europe e.V. <https://fsfe.org>
#
# SPDX-License-Identifier: CC-BY-SA-4.0
```

To check against the recommendations, use `reuse lint`:

```
~/Projects/reuse-tool $ reuse lint
[...]

Congratulations! Your project is compliant with version 3.0 of the REUSE Specification :-)
```

This tool can do various more things, detailed in the documentation. Here a
short summary:

- `addheader` --- Add copyright and/or licensing information to the header of a
  file.

- `download` --- Download the specified license into the `LICENSES/` directory.

- `init` --- Set up the project for REUSE compliance.

- `lint` --- Verify the project for REUSE compliance.

- `spdx` --- Generate an SPDX Document of all files in the project.

- `supported-licenses` --- Prints all licenses supported by REUSE.

### Run in Docker

The `fsfe/reuse` Docker image is available on
[Docker Hub](https://hub.docker.com/r/fsfe/reuse). With it, you can easily
include REUSE in CI/CD processes. This way, you can check for REUSE compliance
for each build. In our [resources for developers](https://reuse.software/dev/)
you can learn how to integrate the REUSE tool in Drone, Travis, GitHub, or
GitLab CI.

You can run the helper tool simply by providing the command you want to run
(e.g., `lint`, `spdx`). The image's working directory is `/data` by default. So
if you want to lint a project that is in your current working directory, you can
mount it on the container's `/data` directory, and tell the tool to lint. That
looks a little like this:

```bash
docker run --rm --volume $(pwd):/data fsfe/reuse lint
```

You can also provide additional arguments, like so:

```bash
docker run --rm --volume $(pwd):/data fsfe/reuse --include-submodules spdx -o out.spdx
```

There are a number of tags available:
- `latest` is the most recent stable release.
- `dev` follows the `master` branch of this repository. Up-to-date, but
  potentially unstable.
- `latest-extra` has a few extra packages installed, currently `openssh-client`.
- `latest-debian` is based on `python:slim`. It is larger, but may be better
  suited for license compliance.

### Run as pre-commit hook

You can automatically run `reuse lint` on every commit as a pre-commit hook for
Git. This uses [pre-commit](https://pre-commit.com/). Once you
[have it installed](https://pre-commit.com/#install), add this to the
`.pre-commit-config.yaml` in your repository:

```yaml
repos:
  - repo: https://github.com/fsfe/reuse-tool
    rev: latest
    hooks:
      - id: reuse
```

Then run `pre-commit install`. Now, every time you commit, `reuse lint` is run
in the background, and will prevent your commit from going through if there was
an error.

### Changed

- Use UTF-8 explicitly when reading files (#242)

### Fixed

- Updated license list to 3.11.

## 0.11.1 - 2020-06-08

### Fixed

- Similar to CAL-1.0 and CAL-1.0-Combined-Work-Exception, SHL-2.1 is now ignored
  because it contains an SPDX tag within itself.

## 0.11.0 - 2020-05-25

### Added

- Added `--skip-unrecognised` flag to `addheader` in order to skip files with
  unrecognised comment styles instead of aborting without processing any file.

### Changed

- Always write the output files encoded in UTF-8, explicitly. This is already
  the default on most Unix systems, but it was not on Windows.

- All symlinks and 0-sized files in projects are now ignored.

### Fixed

- The licenses CAL-1.0 and CAL-1.0-Combined-Work-Exception contain an SPDX tag
  within themselves. Files that are named after these licenses are now ignored.

- Fixed a bug where `addheader` wouldn't properly apply the template on
  `.license` files if the `.license` file was non-empty, but did not contain
  valid SPDX tags.

## 0.10.1 - 2020-05-14

### Fixed

- Updated license list to 3.8-106-g4cfec76.

## 0.10.0 - 2020-04-24

### Added

- Add support for autoconf comment style (listed as m4).

- More file types are recognised:

  - Cython (`.pyx`, `.pxd`)
  - Sass and SCSS (`.sass`, `.scss`)
  - XSL (`.xsl`)
  - Mailmap (`.mailmap`)

- Added `--single-line` and `--multi-line` flags to `addheader`. These flags
  force a certain comment style.

### Changed

- The Docker image has an entrypoint now. In effect, this means running:

  `docker run -v $(pwd):/data fsfe/reuse lint`

  instead of

  `docker run -v $(pwd):/data fsfe/reuse reuse lint`.

## 0.9.0 - 2020-04-21

### Added

- Added support for Mercurial 4.3+.

- A pre-commit hook has been added.

- When an incorrect SPDX identifier is forwarded to `download` or `init`, the
  tool now suggests what you might have meant.

### Changed

- Under the hood, a lot of code that has to do with Git and Mercurial was moved
  into its own module.

- The Docker image has been changed such that it now automagically runs
  `reuse lint` on the `/data` directory unless something else is specified by
  the user.

### Fixed

- Fixed a bug with `addheader --explicit-license` that would result in
  `file.license.license` if `file.license` already existed.

- Fixed a Windows-only bug to do with calling subprocesses.

- Fixed a rare bug that would trigger when a directory is both ignored and
  contains a `.git` file.

## 0.8.1 - 2020-02-22

### Added

- Support Jinja (Jinja2) comment style.

- Support all multi-line comment endings when parsing for SPDX information.

### Fixed

- Improvements to German translation by Thomas Doczkal.

- No longer remove newlines at the end of files when using `addheader`.

- There can now be a tab as whitespace after `SPDX-License-Identifier` and
  `SPDX-FileCopyrightText`.

## 0.8.0 - 2020-01-20

### Added

- Implemented `--root` argument to specify the root of the project without
  heuristics.

- The linter will complain about licenses without file extensions.

- Deprecated licenses are now recognised. `lint` will complain about deprecated
  licenses.

- ProjectReport generation (`lint`, `spdx`) now uses Python multiprocessing,
  more commonly called multi-threading outside of Python. This has a significant
  speedup of approximately 300% in testing. Because of overhead, performance
  increase is not exactly linear.

- For setups where multiprocessing is unsupported or unwanted,
  `--no-multiprocessing` is added as flag.

- `addheader` now recognises many more extensions. Too many to list here.

- `addheader` now also recognises full filenames such as `Makefile` and
  `.gitignore`.

- Added BibTex comment style.

- Updated translations:

  - Dutch (André Ockers, Carmen Bianca Bakker)
  - French (OliBug, Vincent Lequertier)
  - Galician (pd)
  - German (Max Mehl)
  - Esperanto (Carmen Bianca Bakker)
  - Portuguese (José Vieira)
  - Spanish (Roberto Bauglir)
  - Turkish (T. E. Kalayci)

### Changed

- The linter output has been very slightly re-ordered to be more internally
  consistent.

- `reuse --version` now prints a version with a Git hash on development
  versions. Towards that end, the tool now depends on `setuptools-scm` during
  setup. It is not a runtime dependency.

### Removed

- `lint` no longer accepts path arguments. Where previously one could do
  `reuse lint SUBDIRECTORY`, this is no longer possible. When linting, you must
  always lint the entire project. To change the project's root, use `--root`.

- `FileReportInfo` has been removed. `FileReport` is used instead.

### Fixed

- A license that does not have a file extension, but whose full name is a valid
  SPDX License Identifier, is now correctly identified as such. The linter will
  complain about them, however.

- If the linter detects a license as being a bad license, that license can now
  also be detected as being missing.

- Performance of `project.all_files()` has been improved by quite a lot.

- Files with CRLF line endings are now better supported.

## 0.7.0 - 2019-11-28

### Changed

- The program's package name on PyPI has been changed from `fsfe-reuse` to
  `reuse`. `fsfe-reuse==1.0.0` has been created as an alias that depends on
  `reuse`. `fsfe-reuse` will not receive any more updates, but will still host
  the old versions.

- For users of `fsfe-reuse`, this means:

  - If you depend on `fsfe-reuse` or `fsfe-reuse>=0.X.Y` in your
    requirements.txt, you will get the latest version of `reuse` when you
    install `fsfe-reuse`. You may like to change the name to `reuse` explicitly,
    but this is not strictly necessary.

  - If you depend on `fsfe-reuse==0.X.Y`, then you will keep getting that
    version. When you bump the version you depend on, you will need to change
    the name to `reuse`.

  - If you depend on `fsfe-reuse>=0.X.Y<1.0.0`, then 0.6.0 will be the latest
    version you receive. In order to get a later version, you will need to
    change the name to `reuse`.

## 0.6.0 - 2019-11-19

### Added

- `--include-submodules` is added to also include submodules when linting et
  cetera.

- `addheader` now also recognises the following extensions:

  - .kt
  - .xml
  - .yaml
  - .yml

### Changed

- Made the workaround for `MachineReadableFormatError` introduced in 0.5.2 more
  generic.

- Improved shebang detection in `addheader`.

- For `addheader`, the SPDX comment block now need not be the first thing in the
  file. It will find the SPDX comment block and deal with it in-place.

- Git submodules are now ignored by default.

- `addheader --explicit-license` now no longer breaks on unsupported filetypes.

## 0.5.2 - 2019-10-27

### Added

- `python3 -m reuse` now works.

### Changed

- Updated license list to 3.6-2-g2a14810.

### Fixed

- Performance of `reuse lint` improved by at least a factor of 2. It no longer
  does any checksums on files behind the scenes.

- Also handle `MachineReadableFormatError` when parsing DEP5 files. Tries to
  import that error. If the import is unsuccessful, it is handled.

## 0.5.1 - 2019-10-24 [YANKED]

This release was replaced by 0.5.2 due to importing
`MachineReadableFormatError`, which is not a backwards-compatible change.

## 0.5.0 - 2019-08-29

### Added

- TeX and ML comment styles added.

- Added `--year` and `--exclude-year` to `reuse addheader`.

- Added `--template` to `reuse addheader`.

- Added `--explicit-license` to `reuse addheader`.

- `binaryornot` added as new dependency.

- Greatly improved the usage documentation.

### Changed

- `reuse addheader` now automatically adds the current year to the copyright
  notice.

- `reuse addheader` preserves the original header below the new header if it did
  not contain any SPDX information.

- `reuse addheader` now correctly handles `.license` files.

- Bad licenses are no longer resolved to LicenseRef-Unknown<n>. They are instead
  resolved to the stem of the path. This reduces the magic in the code base.

- `.gitkeep` files are now ignored by the tool.

- Changed Lisp's comment character from ';;' to ';'.

## 0.4.1 - 2019-08-07

### Added

- `--all` argument help to `reuse download`, which downloads all detected
  missing licenses.

### Fixed

- When using `reuse addheader` on a file that contains a shebang, the shebang is
  preserved.

- Copyright lines in `reuse spdx` are now sorted.

- Some publicly visible TODOs were patched away.

## 0.4.0 - 2019-08-07

This release is a major overhaul and refactoring of the tool. Its primary focus
is improved usability and speed, as well as adhering to version 3.0 of the REUSE
Specification.

### Added

- `reuse addheader` has been added as a way to automatically add copyright
  statements and license identifiers to the headers of files. It is currently
  not complete.

- `reuse init` has been added as a way to initialise a REUSE project. Its
  functionality is currently scarce, but should improve in the future.

### Changed

- `reuse lint` now provides a helpful summary instead of merely spitting out
  non-compliant files.

- `reuse compile` is now `reuse spdx`.

- In addition to `Copyright` and `©`, copyright lines can be marked with the tag
  `SPDX-FileCopyrightText:`. This is the new recommended default.

- Project no longer depends on pygit2.

- The list of SPDX licenses has been updated.

- `Valid-License-Identifier` is no longer used, and licenses and exceptions can
  now only live inside of the LICENSES/ directory.

### Removed

- Removed `--ignore-debian`.

- Removed `--spdx-mandatory`, `--copyright-mandatory`, `--ignore-missing`
  arguments from `reuse lint`.

- Remove `reuse license`.

- GPL-3.0 and GPL-3.0+ (and all other similar GPL licenses) are no longer
  detected as SPDX identifiers. Use GPL-3.0-only and GPL-3.0-or-later instead.

### Fixed

- Scanning a Git directory is a lot faster now.

- Scanning binary files is a lot faster now.

## 0.3.4 - 2019-04-15

This release should be a short-lived one. A new (slightly
backwards-incompatible) version is in the works.

### Added

- Copyrights can now start with `©` in addition to `Copyright`. The former is
  now recommended, but they are functionally similar.

### Changed

- The source code of reuse is now formatted with black.
- The repository has been moved from <https://git.fsfe.org/reuse/reuse> to
  <https://gitlab.com/reuse/reuse>.

## 0.3.3 - 2018-07-15

### Fixed

- Any files with the suffix `.spdx` are no longer considered licenses.

## 0.3.2 - 2018-07-15

### Fixed

- The documentation now builds under Python 3.7.

## 0.3.1 - 2018-07-14

### Fixed

- When using reuse from a child directory using pygit2, correctly find the root.

## 0.3.0 - 2018-05-16

### Changed

- The output of `reuse compile` is now deterministic. The files, copyright lines
  and SPDX expressions are sorted alphabetically.

### Fixed

- When a GPL license could not be found, the correct `-only` or `-or-later`
  extension is now used in the warning message, rather than a bare `GPL-3.0`.
- If you have a license listed as `SPDX-Valid-License: GPL-3.0-or-later`, this
  now correctly matches corresponding SPDX identifiers. Still it is recommended
  to use `SPDX-Valid-License: GPL-3.0` instead.

## 0.2.0 - 2018-04-17

### Added

- Internationalisation support added. Initial support for:
  - English.
  - Dutch.
  - Esperanto.
  - Spanish.

### Fixed

- The license list of SPDX 3.0 has deprecated `GPL-3.0` and `GPL-3.0+` et al in
  favour of `GPL-3.0-only` and `GPL-3.0-or-later`. The program has been amended
  to accommodate sufficiently for those licenses.

### Changed

- `Project.reuse_info_of` now extracts, combines and returns information both
  from the file itself and from debian/copyright.
- `ReuseInfo` now holds sets instead of lists.
  - As a result of this, `ReuseInfo` will not hold duplicates of copyright lines
    or SPDX expressions.
- click removed as dependency. Good old argparse from the library is used
  instead.

## 0.1.1 - 2017-12-14

### Changed

- The `reuse --help` text has been tidied up a little bit.

### Fixed

- Release date in change log fixed.
- The PyPI homepage now gets reStructuredText instead of Markdown.

## 0.1.0 - 2017-12-14

### Added

- Successfully parse old-style C and HTML comments now.
- Added `reuse compile`, which creates an SPDX bill of materials.
- Added `--ignore-missing` to `reuse lint`.
- Allow to specify multiple paths to `reuse lint`.
- `chardet` added as dependency.
- `pygit2` added as soft dependency. reuse remains usable without it, but the
  performance with `pygit2` is significantly better. Because `pygit2` has a
  non-Python dependency (`libgit2`), it must be installed independently by the
  user. In the future, when reuse is packaged natively, this will not be an
  issue.

### Changed

- Updated to version 2.0 of the REUSE recommendations. The most important change
  is that `License-Filename` is no longer used. Instead, the filename is
  deducted from `SPDX-License-Identifier`. This change is **NOT** backwards
  compatible.
- The conditions for linting have changed. A file is now non-compliant when:
  - The license associated with the file could not be found.
  - There is no SPDX expression associated with the file.
  - There is no copyright notice associated with the file.
- Only read the first 4 KiB (by default) from code files rather than the entire
  file when searching for SPDX tags. This speeds up the tool a bit.
- `Project.reuse_info_of` no longer raises an exception. Instead, it returns an
  empty `ReuseInfo` object when no reuse information is found.
- Logging is a lot prettier now. Only output entries from the `reuse` module.

### Fixed

- `reuse --ignore-debian compile` now works as expected.
- The tool no longer breaks when reading a file that has a non-UTF-8 encoding.
  Instead, `chardet` is used to detect the encoding before reading the file. If
  a file still has errors during decoding, those errors are silently ignored and
  replaced.

## 0.0.4 - 2017-11-06

### Fixed

- Removed dependency on `os.PathLike` so that Python 3.5 is actually supported

## 0.0.3 - 2017-11-06

### Fixed

- Fixed the link to PyPI in the README.

## 0.0.2 - 2017-11-03

This is a very early development release aimed at distributing the program as
soon as possible. Because this is the first release, the changelog is a little
empty beyond "created the program".

The program can do roughly the following:

- Detect the license of a given file through one of three methods (in order of
  precedence):
  - Information embedded in the .license file.
  - Information embedded in its header.
  - Information from the global debian/copyright file.
- Find and report all files in a project tree of which the license could not be
  found.
- Ignore files ignored by Git.
- Do some logging into STDERR.
