Hello,If librecad had a GPLv2+ plugin example code, I could upgrade that to v3 and implement libredwg.if librecad has an interface, it does not matter what code is behind it.we can also define a data interface that just uses files.LibreCAD has a interface where it's not possible that a plugin can call LibreCAD or LibreCADcan call the plugin. Everything must go though the plugin's interface.All communication goes through the documen_interface,for example if a plugin needs to add a line then we have a virtual functionfor it : virtual void addLine(QPointF *start, QPointF *end) = 0;
And we have a QC_PluginInterface in case LibreCAD needs to call upthe plugin.
sounds like we are good, right?
I dont see any technical or legal problems.mikeOn Sat, Feb 11, 2012 at 6:24 PM, R. van Twisk <address@hidden> wrote:
On this subject,
If LibreCAD has a plugin architecture that can be build outside of the LibreCAD tree, and this
plugin architecture is licensed as GPLv2+.
Can we then use LibreDWG within LibreCAD through out plugin architecture?
LibreCAD would never beable to call the plugin directly, and the plugin would
never beable to call LibreCAD code. In such case. Because the plugin architecture
would function as a interface between the two parts, essentially being
100% separated. Any data structure that exists is already licensed as GPLv2+
so not a single line of Code and/or data structure LibreDWG can see has a GPLv2 license
Are we good then?
