Release 1.0.0

[nx10]

This is a tracking issue for major tasks that have to be done for a 1.0.0 release. The goal is to ship a reliable and fast graphics device and a HTML/JS client that is easy to use. Bugfixes and small feature requests will also be worked on when they arise.

Backend

• [x] Use Boost Beast
  • [x] Get beast servers (http & websocket) to compile + run in an R package (done!)
  • [x] Switch from cpphttplib server to beast
  • [x] Implement websockets
• [x] Unit tests (If you want to contribute, this would be a great way to start)
• [x] Generate better SVGs
  • [x] Improve SVG rendering (Number formatting, string building, ...)
• [x] Offline mode

HTML/JS Client

• [x] Handle websockets (and optionally polling, if ws are not available)
• [x] Display disconnected status (https://github.com/nx10/httpgd/issues/23)
• [x] Render PNG / raster graphics (https://github.com/nx10/httpgd/issues/9)

Other

• [x] Create logo
• [x] Investigate build and R CMD CHECK output for all platforms (Win, Linux, macOS)
• [x] Clean up code & meta data
• [x] Release 1.0.0 to CRAN

After 1.0

• [x] Improve documentation
• [ ] Replace Belle (might not be necessary: https://github.com/octobanana/belle/issues/13)
• [x] Consider switching from Rcpp to cpp11
• [ ] Analyze draw call data to generate small optimized SVGs

Just a small update on this: The only thing blocking CRAN release right now is this CMD check warning which only happens with the Windows build. My best guess is that it is caused by the way I had to combine the boost beast headers with the boost headers of the BH package.

I hope this will be resolved with the next BH update (https://github.com/nx10/httpgd/issues/40), which will probably happen a couple days after boost 1.75 releases this week.

Another update: The new BH version will be out in January. I got the development version from GitHub (after some fixes to Belle) working and was able to run httpgd without any additional boost headers. The bad news is that the compiler warning persists. I will now try a couple of things to isolate the problem, if those fails as well, I will try to contact the CRAN team directly.

Edit: I finally fixed it (dfb080ecf472f2718f6d4e6aa900c47b957f4791), will wait for BH to update then submit to CRAN 🎉
