REUSE notes

• Adding headers
  • Styles
• Generic commands
• License identifiers I commonly use

reuse is a tool for compliance with the REUSE recommendations.

says their GitHub description and in practice this means having a license header in all files or alternatively a file.license file. The tool can generate these, but I never remember the commands.

For more detailed explanation, consult reuse.software/tutorial

---

Adding headers

Copy-paste and add file name(s) to the end

# Autodetect how to add comment?
reuse annotate --copyright="Aminda Suomalainen <{{ page.email }}>" --license="CC0-1.0"
# Create a file.license
reuse annotate --copyright="Aminda Suomalainen <{{ page.email }}>" --license="CC0-1.0" --force-dot-license
# The usual # marks a comment
reuse annotate --copyright="Aminda Suomalainen <{{ page.email }}>" --license="CC0-1.0" --style python

Note!

• --year 2023 can be specified if the date isn’t this year.
• annotate replaces existing headeer if any, to add before it instead, use --no-replace

Styles

• c means // marks a comment
• python means # marks a comment
• html and css explain themselves
• tex means % marks a comment
• vim means " marks a comment
• etc. when style is empty, supported ones are displayed, but I am unsure whether I need more and trying what reuse says works too.

Generic commands

• reuse download --all - downloads all licenses found to LICENSES/
• reuse lint - verifies compliancy
• reuse supported-licenses | less - lists supported licenses identifiers
