The byesig extension is one of my favorites when doing Ruby+Sorbet coding. I forked it to create ByeSpec to do the same for Elixir specs. Here’s how I use it:
Before
After
On a light theme
I want to see my specs, but I also want to reduce visual noise from so much text on the screen. Opacity and some other settings are configurable, like the option to show the green markers in the left-hand column. Personally, they help me navigate my code, seeing where the functions begin.
Byesig does code folding too for the Sorbet sigs, which needs a little effort to get working with specs.
This is v1.0.0 and my first IDE extension, so YMMV.
