Take any amount of delimiter pairs (on a single line) and display them spaced out vertically to concisely emphasize complex nested pairs.
Select some text, right click and select the option Visualize Delimiters
Selecting it will display an in-line peek dropdown of the visualized text.
Inspired by tedious tasks during Chapman University's Programming Languages course (Alex Kurz), in which we frequently dove into theory of Lambda Calculus, implemented in Haskell.
Numerous exercises had lambda calculus statements with a tremendous amount of nested parenthesis, which made pen and paper analysis of these statements a nightmare.
The bracket colorization extension (now a native feature) helped some. However, a vertical space implementation sounded more useful and a fun idea for a final project.
The VSCode extension development documentation is pretty bare bones. Pioneering a combination of concepts and objects in the documentation requires pure experimentation and problem solving.
Even when finding similar questions (barely any on stackoverflow relating to my issues regarding peekLocations alternative), did not help much. Per a recommendation on github issues, I initially resisted going onto the VSCode slack, but gave up and got some pointers pretty quickly.
Lesson: Communities exist for a reason, reach out for help!
