Those are my personal dotfiles. Or at least the ones that I care about.
It has i3-bar with a custom color scheme matching my current pywal scheme. It was modified manually, so when using a different color scheme, if you want to change i3 bar's look modify it manually based on your new scheme.
I use suckless st as my terminal, but usually just pick Luke Smith's fork, which integrates many patches that otherwise I have to apply manually. This one is important for easy pywal color scheme integration.
For a quick "pop-up" browser I'm using suckless surf, with this patch, which allows me to quickly search for something with $mod + s shortcut. This really helps me on my daily workflow.
My setup uses plugged for plugin management. It has a onedark theme as well as pywal color scheme integration (if you want to use it, but I usually prefer to stick with onedark).
Furthermore, and more important, it uses vim-go, and coc for Language Server support, which together makes for a very good golang development environment.
It also has Rust support with it's official plugin as well as it's language server integration with coc.
