golden-ratio | Seed web map tile caches using remembered hot spots

The idea is to do something similar to what Golden Ratio (the vim plugin) does. But instead of sizing to a "golden ratio", I want to set a specific size to the unselected windows.

Ex:

Using Neovim's terminal emulator to run code alongside my code has become an essential part of my workflow ever since I found out about it. I however would like to have a way to make it so that when I open a new nvim terminal window it will be narrow opposed to currently when I open one and it takes up half the screen.

I don't fully understand vimscript which is part of the issue here. I have looked into how to make an autocommand run based on a filetype and how to resize windows and cobbled together something based on these. It doesn't work as it resizes the whole vim session instead of just the desired window.

I wrote a procedure golden-ratio to compute the Golden Ratio. The first argument is the number where we start computing the golden ratio and the second argument is the number of times we'll be repeating the recursion.

I'm trying to create a responsive layout based on the Golden Ratio (1:1.618) and I want it to be infinitely recursive.

I know, it will never be used after so many layers deep, but I started obsessing over the fact that I can't figure out how to make it infinitely recursive!

Here it is:

I have this amateur function that changes the box-shadow on a group of elements based on the window.scrollTop position and element offset. When the user scrolls up or down from the photos, the box-shadow will move down or up respectively. So it gives the illusion of perspective. When these photo elements are in the center of the screen, the box-shadow is centered.

Right now it's not ideal and by that I mean it isn't very symmetrical and doesn't feel right. I know it because my "golden-ratio" (Not the actual Phy golden ratio, i just used this as a variable name) is just a random number. I know there is a way to use my variables to set this up properly I just can't come up with it. Looking for golden ratio (box-shadow vertical offset) to be from about -20 to 20, 0 when centered, seems to look okay.

So my question is can anyone optimize my algorithm so that the box-shadow changes as described above but more realistic?

• This should only happen inside a certain vertical scroll window so that this function isn't running while the photos are off the screen (already pretty much implemented)
• The box-shadow change is subtle so there is not a HUGE shadow above or below it.
• In my real code I have another function that changes the photos to be the same height as the width on window resize. Here I just have a fixed height of 160px.

Here is my code (modified to give a barebones example). Feel free to redo my function from scratch if that is cleaner.
