[Question] How to change the licence from Apache-2.0 to GPL-3.0-only ?

[Martin15135215]

When I used the command nbdev_new it created a settings.ini with license = apache2., How can I change it to GPL-3.0-only ?

And why is the SPDX short identifier not used?

I found the possible licence in the setup.py:

nbdev/setup.py

Lines 19 to 26 in 96deb7a

	licenses = {
	'apache2': ('Apache Software License 2.0','OSI Approved :: Apache Software License'),
	'mit': ('MIT License', 'OSI Approved :: MIT License'),
	'gpl2': ('GNU General Public License v2', 'OSI Approved :: GNU General Public License v2 (GPLv2)'),
	'gpl3': ('GNU General Public License v3', 'OSI Approved :: GNU General Public License v3 (GPLv3)'),
	'agpl3': ('GNU Affero General Public License v3', 'OSI Approved :: GNU Affero General Public License (AGPLv3)'),
	'bsd3': ('BSD License', 'OSI Approved :: BSD License'),
	}

First Question:

There is a GPL-3.0-only and GPL-3.0-or-later. what is with gpl3 meant?

Second Question:

How to change a licence in an already created nbdev project?

I did:

➤ nbdev_new
# Please enter a value for repo
repo = test
# Please enter a value for branch
branch = main
# Please enter a value for user
user = test
# Please enter a value for author

And then changed in the settings.ini the licence apache2 from to gpl3, however what do i need to do, that the Licence file changes?

Possible solution: #1391

Third Question:

How to create a nbdev project directly with GPL-3.0-only?

I did:

➤ nbdev_new --license gpl3
# Please enter a value for repo
repo = test
# Please enter a value for branch
branch = main
# Please enter a value for user
user = test
# Please enter a value for author
author = test
# Please enter a value for author_email
author_email = [email protected]
# Please enter a value for description
description = test

In the settings.ini, the value for licence was gpl3 however the licence file was still apache2?

So I did a quick check of the code for nbdev_new

nbdev/nbdev/cli.py

Line 80 in 96deb7a

def nbdev_new(**kwargs):

And I think with this URL only the template is downloaded

nbdev/nbdev/cli.py

Line 91 in 96deb7a

url = f"https://github.com/fastai/nbdev-template/archive/{tag}.tar.gz"

in the template is always with apach2 licence file
