When something uses these licenses does it mean that you are free to use within your plugins?
I only ask because these are under ckeditor and htmlpurifier
Am I able to use these within our latest plugin.
ckeditor is available under GPL, LGPL and MPL. In your case since you will be linking to it, LGPL or MPL will kick in which is fine. Either one of these two licenses will ensure that your main app can be licensed proprietary, hence your covered.
As for htmlpurifier, it appears to be LGPL, which won’t affect the proprietary parts of your application either.
In both cases, the only thing the licensing wont cover is if you have modified ckeditor or htmlpurifier, then those modifications have to retain the original licenses, i.e. LGPL/MPL.
EDIT: Just noticed you mentioned plugin specifically. If your asking with regards to WordPress usage, ckeditor is GPL compatible, so your covered on that end. Also with htmlpurifier, your covered, though you will be contaminating the original GPL license wherein you are linking to a library that is LGPL ( lesser strict license). It should still be fine if your not planning on releasing your plugin as pure GPL.
IANAL, so keep in mind that this is my personal interpretation of the licensing terms.
Hi thanks for the reply
No this in not going with Wordpress or any other framework
I stated plugin, but I fact it’s going to be a custom built cms site but we will be submitting to codecanyon instead as it is going to be aiming at developers from places like envato marketplaces
