Week 11 of GSoC

Week 11 of GSoC is done! 🎉😸💻 _{^{Phew, it’s been a while since the last update!}}

The following is a progress report since the last post.

Milestones – Makie.jl and AbstractPlotting.jl

• continually updated Makie and AbstractPlotting packages, bringing updates and improvements to documentation and additional tutorials.
• extension of the Documenter.Selectors.matcher and Documenter.Selectors.runner to match custom-defined keywords using regex, and perform actions based on the match captures
  • as an example you can now write @example_database("Contour3d") in the documentation.md source Markdown file, and during compile, the source code + the plot of the example will be automatically inserted
  • likewise, @example_database("Contour3d", code) inserts only the source code, and
  • @example_database("Contour3d", plot) inserts only the plot ^{(oh, the magic of regex 😍)}
• implementation of a Stepper class that allows one to step! through example plots, and save a plot at each step

    mutable struct Stepper
          scene::Scene
          folder::String
          step::Int
    end
  
    function step!(s::Stepper)
        Makie.save(joinpath(s.folder, basename(s.folder) * "-$(s.step).jpg"), s.scene)
        s.step += 1
        return s
    end
  

• these stepper examples are great for showing off progressive changes in plots, such as demonstrating the effects of theming or changing data:

• the stepper examples are automatically generated when compiling the documentation, and inserted on the fly
  • as above, we can also write @example_database("Theming", stepperplot) in the documentation.md to insert stepper plots automatically
• for some more stepper examples, consult the Makie documentation, which is available online!

Mergers (& Acquisitions)

• two PRs to branch master on AbstractPlotting merged🎉! #2, #4.
• three major PRs to branch master on Makie containing many documentation changes are merged🎉!! They are: #99, #111, and #114.
• AND… the Gitlab CI pipeline for visual regression tests actually passed, for once!

_{^{The “failed” status with the documentation postprocessing step is due to a missing package on the CI, and should be fixed soon.}}

• I also implemented some subscenes examples, e.g.:

surface + contour3d plot

surface + wireframe + contour plot

Check these examples out in the examples3d.jl library!

One more thing…

• I started exploring some implicit plots, and plots involving inequalities, these generate some pretty interesting-looking plots:

And lastly… a spacecraft from a galaxy far, far away

These examples are saved in the implicits.jl library, so feel free to check them out! 😀☝

TODOs

• add more documentation pages, including proper documentation of the Stepper class
• making a poster for JuliaCon 2018 in London, UK, which is in 11 days! I will be attending and presenting a poster as part of my GSoC project under the Julia organization, along with a few other GSoC students. Huge thanks to NumFOCUS for sponsoring us!!

So, that’s it! Hope you enjoyed reading this. Onwards to the last 10 days of coding 👨‍💻!
