My new thesis - Go Linter in Rust

Thesis Project Idea

Hello everyone, I am in the last year of my Bachelor's Degree in Software Engineering, which means I need to complete a thesis to officially finish.

I wanted to do something challenging and outstanding. My initial idea was to implement a text/code editor in Rust. While that idea had potential—it’s easy to layer a text editor and add new features—I wanted to create something genuinely useful. Let's be real: no one would use my editor, which would essentially be a low-budget copy of Zed.

Final Idea

I decided to switch to creating a Go Linter implemented in Rust.

I know the Go community is strict, so implementing my own rules from scratch would make little sense. Then the perfect idea came to me:

Base the linting rules on the popular book "100 Go Mistakes and How to Avoid Them" by Teiva Harsanyi.
This book is widely accepted in the Go community as a reference for writing good Go code.
The linter can be layered.
I could write my own parser or use an existing one.
I might implement a domain-specific language (DSL) for defining linting rules, as my mentor is well-versed in DSLs.

These aspects are still open questions, but I’m really excited about this project. It could potentially be used by others—who knows, maybe it will become the Go equivalent of Ruff for Python.

Thanks for reading. Cya.

College student sets up NEOVIM!!!!

Neovim Setup Update

It's been a while since I last wrote, hehe, my bad. Don't think anyone waits for my posts though.

After setting up my system to my liking (check previous posts), I hopped into my Neovim configuration. I set up almost everything: LSPs, Treesitter, Telescope, formatters, linters, and some QoL plugins. Let's dive into these configs.

Core Setup

Setting up Treesitter, LSPs, and Telescope was pretty easy. I use lazy.nvim for plugin management.

After adding it, I experimented with different languages, downloading a few LSPs and popular linters:

pyright (LSP for Python)
ruff (gigafast Python linter)
vtsls (modern TypeScript LSP)

Telescope is really nice as a fuzzy finder for navigation. I heard fzf-lua is much better, but for now Telescope gets the job done.

Additional Plugins

Neotree

I use this in case I forget a file name (rare occasion, I'm still young).
Autocompletions

Surprisingly, autocompletion requires 4-5 plugins. I was expecting an all-in-one plugin but didn’t find one. Currently, I accept suggestions via <Enter>, but this sometimes interferes when I want to break a line in Insert Mode. I might switch it to <C-y>.
Theme

The most important part of any editor is the theme. I use Nord, which blends nicely into my defrosted system theme.

Quality of Life Plugins

All QoL plugins are from mini.nvim:

indentscope: Helps keep track of indentation
pairs: Auto-bracketing
move: Allows moving blocks of code via Alt+h/j/k/l

These additions make editing smoother without much bloat. My setup is much less bloated than LazyVim, for example.

Future Plans

I am thinking about adding bufferline.nvim to have a VSCode-like experience. For now, I want to try out harpoon2 for secondary navigation, while Neotree remains tertiary.

Thanks for reading. Cya.

College student starts getting good at ricing (kinda)

Customizing My Omarchy Setup — Progress Update

In my last post, I dove into the world of Omarchy (Arch) with the goal of creating an aesthetic, productive, and minimalistic system that I fully control. The aesthetic part is coming along nicely.

I’m currently working on my own theme called Defrosted, heavily inspired by bjarneo’s Omarchy Frost theme. My plan is to make it a bit more colorful while keeping the focus on blue variants.

Visual Setup Progress

Since my last post, I’ve modified my background, Waybar, shell prompt, and Walker app launcher.

Background

For the background, I wanted something snowy, cloudy, and cold, with a darker tone for better contrast. Following DHH’s advice, I browsed through dharmx’s wallpaper collection for a while and eventually landed on this one:

Waybar

I spent quite some time tweaking my Waybar. My goal was to have each section (left, center, right) clearly separated, with each showing only the essential information.

After reading the documentation and experimenting with CSS IDs and class names (which wasn’t exactly smooth), I finally arrived at this result:

The left module contains only the workspaces.

The center module shows the day of the month (e.g., 13th) and the time in 24-hour format.

At first, when I heard ThePrimeagen talk about this format, I thought it was a bad idea — why not include the month or the day of the week? But after thinking it through, he’s right. These two pieces of information tell me everything I need: I already know what month it is, and I don’t need to be reminded of the weekday. Thanks, ThePrimeagen.

Shell Prompt

As I plan to use the terminal a lot, I wanted my shell prompt to feel special. Omarchy ships with Starship, and my first idea was to use the Tokyo Night style:

While it looks great, it’s a bit too much for me. Even though I could adjust what’s displayed, it didn’t align with my minimalistic goals.

So, I ended up with this cleaner version:

It shows the last three directories (in a stylish way), and when I’m inside a Git repository, it displays the current branch:

In this screenshot, I’m in the base folder of the repository, so only that directory name is visible.

Walker App Launcher

Lastly, I tweaked my Walker launcher — mainly color adjustments and rounded corners. Unfortunately, I can’t screenshot it for some reason, so you’ll have to take my word that it looks good.

Thanks for reading!

See you next time.

CS College Students Tries Real OS (Omarchy btw)

My Experience Switching to Omarchy

I hate nothing more than using Windows' built-in search functionality. It can't find anything and is slower than me finding memory bugs. I would rather learn combinatorics again than use Windows search.

And that is one of the reasons I wanted to try out a Linux distro. As a young, manipulative, and inexperienced college student, I chose the most hyped distro — Omarchy.

Installation

So, I built in another SSD in my laptop, downloaded the ISO, and installed Omarchy. I already had a Linux Mint install before with i3 and a really nice Neovim config, and I wiped the whole thing for this new OS.

First impressions:

WOW, this is so much better than i3 — the animations, the colors, everything looked perfect.

Realizations and Customizations

After a few days, I realized something was missing:

I don’t want to use Chromium — I want Firefox.
But I don’t want vanilla Firefox — I want custom Firefox.
I don’t want these Hyprland keybindings — I want i3-style keybindings.

Slowly, I realized I would need to change a lot of things, so I got to work.

Firefox Tweaks

Firstly, I riced my Firefox with FF Ultima.

Then I wanted to add custom keybindings to it (I like to use Ctrl + 1 to move right in my tabs and Ctrl + 2 to move left in my tabs) and realized it's not supported natively.

Everyone on the internet said I should upvote a post on Mozilla Connect and wait for the dev team to add the functionality. The post is more than 3 years old 😅.

Hyprland Keybindings

Then I changed my Hyprland keybindings.

SUPER + W closes windows — do you know what's close to SUPER + W? Ctrl + W.

Do you know what that means?

I want to close a browser tab and I accidentally close the whole window 😭.

Fortunately, Firefox allows reopening recently closed tabs with Ctrl + Shift + T.

I also realized there was no way (or at least I didn’t find any) to resize windows, so I added keybindings to resize active windows in any direction.

What’s Next

I still have a long way to go in my ricing journey.

Omarchy comes with LazyVim, but for some reason I don’t like it. So, I’ll probably make my own config with kickstart.nvim**.

Also, the default Waybar looks kinda empty. These two configs are my main focus for the future.

Cya.
