[Help-librejs] Fixing nontrivial and nonfree JS

[christophe . jarry]

Hello,

In order to make http://hydra.gnu.org/ appear clean to librejs
regarding nontrivial and nonfree javascript, I need some help. I
reported the issues detected by librejs on
http://lists.gnu.org/archive/html/bug-guix/2013-10/msg00001.html.

To summarize, some explanations are needed:

>>     NONTRIVIAL: eval has been found in code:
>>     http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.1/jquery-ui.min.js
>>
>>     NONTRIVIAL: eval has been found in code:
>>     http://hydra.gnu.org/static/bootstrap/js/bootstrap.min.js
>
>So jquery itself is free, but since it's using 'eval' it might be
>evaluating third-party non-free code, is that right?

>>     This script is detected as nonfree, external, and as defining
>>     functions or methods:
>>     http://hydra.gnu.org/static/js/bootbox.min.js
>
>That file points to http://bootboxjs.com/license.txt, which is the
>MIT/X11 license.

>So do I get it right that it's just a matter of letting LibreJS know

Thank you for your help,
