In this last report of what was done during the Google Summer of Code I want to review the tasks done, the pending and the new tasks that arose from what was done.

The main goal was to have a ground routing configuration page in Lime-app (simple GUI for Libremesh router management). This main  goal was achieved.

Currently there are two pull-request modules that incorporate this functionality, both in the view (https://github.com/libremesh/lime-app/pull/153) and in the ubus modules (https://github.com/libremesh/lime-packages-ui/pull/20).

In addition, the interface is translated into English and Spanish and incorporated into the wikitransalte scheme that uses libremesh.

Unsuccessful goals

I had set myself the extra goal of designing the same user interface for LuCi, which unfortunately I didn’t get to implement.

To do

In the interface you can configure a single link (link1), the job that remains to be done is to save multiple links and edit them one by one. It doesn’t mean a great job and I’ll continue it until I do.

Another pending task is to program the administrative pages to be hidden from the menu until the administrator logs in, this is something related to the lime-app design and must be solved. The average user of libremesh does not need to make use of ground routing and therefore displaying it in the menu would only generate confusion and possibly configuration errors.

Acknowledgements

I want in this last post to thank the Freifunk community, the LibreMesh team and especially Gio for his work as a mentor, he was always there to answer my questions and concerns. Finally, I would like to thank Google Summer of Code for its efforts during all these years and for its commitment to the development of open source software. Thank you very much, everyone.

Result

In these three months I was working on the implementation of Luci2 (the graphic interface of LEDE / OpenWrt). The project was to translate the functionalities that Libremesh currently uses in Luci to the new proposal. The new environment consists of a backend based on UBUS that exposes JSON with data and the structure of the view.

As far as Google Summer of Code goes, I was able to make the ubus modules that emit information about bmx6, batman-adv, alignment, spectrum analysis, libremap and finally a series of several utilities. The results can be found in the lime-packages-ui repository.

Each module has its documentation on the calls and the expected answers.

  • get_cloud_nodes

To future

Finally I want to clarify that it is my intention to continue until achieving a complete implementation with the front end and keep the packages made. I will adapt the current luci packages to consume the data from the UBUS modules, so its use can be immediate and not wait for the complete development of luci2.

Thanks to the Freifunk community and the Libremesh team for giving me the opportunity to participate in this GSoC. No doubt I will continue to contribute to free software, to have more community and free networks.

In this month I was making several advances in the implementation of Luci2 in Libremesh. Mainly the tasks were to generate a image of the firmware with Luci2 and analyze through a study of the traffic the way in which the rpc acutally builds the menu and manages the ACLs. The idea is to reduce the size to the maximum so that its use is feasible and at the same time reduce the dependency to the frontend frameworks.

All this was possible because I traveled to the Battelmesh in Vienna, where I was able to meet and talk with different members of the team and especially with Jow, who explained the current state of development and put me in contact with other developers. We also talked about possible changes and implementations to ensure some retrocompatibility or at least a simple form of migration from Luci to Luci2.

What am I doing

• Provisioning a rendering system on the client based on a JSON structure (not yet fully determined)
• Analyzing how to modify the output of CBI so that the output is not an html but a JSON structure
• Trying to implement an automatic view generator for exposed elements in uci via ubus and rpc
