Hi,

it would be great if licensecheck would support SPDX-License-Identifier
headers.
See
https://spdx.org/licenses/
https://spdx.org/sites/cpstandard/files/pages/files/using_spdx_license_list_short_identifiers.pdf

This would indeed be helpful.

libtommath is now using SPDX-License-Identifier [1]
and licensecheck extracts no useful information.

All the best

Dod

Hi there,

are the any news here?
Judging from
https://codesearch.debian.net/search?q=SPDX-License-Identifier
SPDX-License-Identifier usage seems to be quite significant already.

Regards,
Michael

Licensecheck does not yet support SPDX-License-Identifier, no.

I agree that it is quite valuable, and it _will_ get implemented.

Quoting Dominique Dumont (2019-01-07 11:48:16)
is licensed as Unlicense which is not yet known to Licensecheck, and
Licensecheck does not yet track alien licenses.

Licenses covered can be seen with "man Regexp::Pattern::License" -
probably useful to expose that information to licensecheck itself.

Sorry for the lack of response till now.

Hello,
please let me add one additional item to this feature.

Assuming SPDX license names are supported and the tool is able to
specifically parse for SPDX-fields.
In this case only that SPDX fields should be considered.
Other licenses strings, e.g. in comments, should be ignored.

See as a good example
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=960665

The problem here is that the whole project does offer SPDX meta data and
"reuse lint" is green on all files.
But one file "serviceHelper.py" does have comments about the license
history of that file. Some other licenses
are named just of historical reasons. License checker does consider that
strings, too. That is the problem.

And by the way: Licensecheck do not need to parse SPDX fields by itself.
Use "reuse" for that. I opened an issue at "reuse" to support machine
readable license infos. https://github.com/fsfe/reuse-tool/issues/1164

Hi c,

Thank you for your contribution here, but please beware that it is not
easily actionable the way you provide it.

I encourage you to file separate bugreports for each actionable point
that you make, targeted the Debian package suitable for acting on it.

It seems you are not talking about changes to licensecheck, but instead
talking about the different tool reuse.  For that, please file a
bugreport against the pseudo-package "wnpp" as described here:
https://www.debian.org/devel/wnpp/#l1

If you want licensecheck to (by itself) detect only SPDX license names
then please file a separate issue about that.

If you want licensecheck to not check licenses but call out to reuse
instead, then please file a separate issue describing how that is
actionable for licensecheck.

In other words, please post to *this* bugreport only for information
relevant to the issue of *extending* licensecheck to cover SPDX
notation.


Kind regards,

 - Jonas
