Converse.js: LibreJS support

[gnunicode]

Can converse.js be made to work with LibreJS? It would be really great, considering that all of the code is libre.

I can't just put the license at the top of converse.min.js because the dependencies are also bundled and they are released under other licenses.

Looks like what's required is a JavaScript web-labels table, which specifies the license for converse.js and each of its dependencies.

https://www.gnu.org/software/librejs/manual/librejs.html#JavaScript-Web-Labels

This table can be placed on a separate HTML page and then links to it are inserted in the other pages in the site.

More info here: https://www.gnu.org/licenses/javascript-labels.html

To be honest, if you care enough about this, then I think you can do the work and make a pull request.

The work required is to identify the license for each dependency and then make the table.
You can add the links if you want, but I can also do that afterwards.

[gnunicode]

OK. I've started work on this and I'll submit a pull request when I've completed it.

[jcbrand]

Wonderful, thanks.

@gnunicode I merged #1001, but then afterwards noticed that you missed lots of licenses for JS dependencies that are bundled into converse.min.js

Here's a list of the files that you missed:

node_modules/otr/build/dep/crypto.js
node_modules/otr/build/dep/salsa20.js
node_modules/otr/build/dep/eventemitter.js
node_modules/otr/build/otr.js
node_modules/strophe.js/strophe.js
node_modules/strophejs-plugin-vcard/strophe.vcard.js
node_modules/strophejs-plugin-disco/strophe.disco.js
node_modules/strophejs-plugin-rsm/strophe.rsm.js
node_modules/strophejs-plugin-ping/strophe.ping.js
node_modules/snabbdom/dist/snabbdom.js
node_modules/snabbdom/dist/snabbdom-attributes.js
node_modules/snabbdom/dist/snabbdom-class.js
node_modules/snabbdom/dist/snabbdom-dataset.js
node_modules/snabbdom/dist/snabbdom-eventlisteners.js
node_modules/snabbdom/dist/snabbdom-props.js
node_modules/snabbdom/dist/snabbdom-style.js
node_modules/lodash/lodash.js
node_modules/backbone/backbone.js
node_modules/backbone.nativeview/backbone.nativeview.js
node_modules/backbone.browserStorage/backbone.browserStorage.js
node_modules/backbone.overview/dist/backbone.overview.js
node_modules/backbone.overview/dist/backbone.orderedlistview.js
node_modules/backbone.vdomview/dist/backbone.vdomview.js
node_modules/awesomplete-avoid-xss/awesomplete.js
node_modules/moment/min/moment-with-locales.js

In order to fetch them, you need to run make dev, they'll then be downloaded and available in the paths above.

[gnunicode]

Thanks, I will get these licenses added as soon as possible

[gnunicode]

Sorry there's been a bit of a delay - I've been busy but also the build system requires Chromium which is blacklisted on my distribution (Parabola) and I've had some difficulties in getting a virtual machine set up to run make dev. However I think I may be able to get all the licenses done tomorrow

[jcbrand]

I think the Chromium dependency is for the tests which run on chrome-headless.

As a hacky workaround, you could just remove the problematic dependency from package.json and try again (don't commit that though).

See here: https://github.com/jcbrand/converse.js/blob/master/package.json#L63

[gnunicode]

Thanks, it worked. I've started adding the licenses now and will create a second pull request when they're done

[jcbrand]

@gnunicode Are you still going to finish this task?

[gnunicode]

Hi, sorry I had completely forgotten about this. I do not think I will be able to though as I have other commitments at the moment.

[Echolon]

Hi @gnunicode

have you re-consider restart working on this?
