Introduction
I am using Neovim for programming.
I was initially already using a certain scrollbar plugin, but it was very simple and could not display git, diagnostic or search results.
I had never made a Neovim plugin before, but when I read the source of the plugin, I decided to make my first neovim plugin nvim-scrlbkun, because it was not too big and I thought I could implement my own plugin based on it.
nvim-scrlbkun displays the cursor position, the results of git, search, diagnostics in addition to a scrollbar itself, with the auto-hiding feature.
I would be happy if you used it.
Implementation
nvim-scrlbkun is written in lua.
I had very little experience with lua, but it was very easy to use and I had no trouble understanding the functional aspects of the language. I was used to a language with classes, so the lack of class functionality was a bit painful for me.
Personally, I find it very similar to JavaScript.
nvim-scrilbkun displays a floating window at the right edge of each window, and draws elements such as search, git, diagnostics, on the floating window as virtual text.
I thought about using only virtual text without floating windows, but gave up because the display collapses if there are long lines that are wrapped.
I had a bit of trouble implementing the display of the search results, since the v:hlsearch, an internal variable of Neovim, does not change at the moment of search, so I decided to delay rendering the results. It is a simple idea now, but it seemed like a very good idea when I first came up with it(I had to remove some resulting bugs, though).
Impressions after implementation
Through this experience, I realized again that the best way to improve coding skills is to read codes excellent people write.
I think it is a waste of time if you are struggling on your own, so there is no way you can avoid using github, where you can immediately see codes written by excellent people.
