In this video, I explain a method I use to learn Vim/Neovim and focus only on what I need, avoiding information overload.
The method consists of 4 steps:
Search and replace in a single file is easy in Neovim, but replacing text across an entire project or workspace can be trickier, or require the help of a plugin.
In this video, I review 5 different methods for search and replace across multiple files:
Just wanted to have some fun I tried to do some animations using cellular-automaton.nvim

Hope you like it!,
If you have done some animations, share them here please!
Lately, I've been getting a bit tired of the overproductivity culture that's everywhere on social media, so I put together a list of plugins to waste time with absolutely no particular purpose.
1 Play Doom - seandewar/actually-doom.nvim
2 Donut - NStefan002/donut.nvim
3 Snake - Febri-i/snake.nvim
4 Cellular Automaton - eandrju/cellular-automaton.nvim
5 Tetris - alec-gibson/nvim-tetris
6 KillSheep - seandewar/killersheep.nvim
7 NyanCat - koron/nyancat-vim
8 VimBeBetter (Vim be good) - szymonwilczek/vim-be-better
9 Christmas three - rhysd/vim-syntax-christmas-tree
10 Pets - MeF0504/vim-pets
11 Sudoku - jim-fx/sudoku.nvim
Marks are really easy to learn and use. Maybe you don't need Harpoon or a similar plugin. In this video, I explain just three commands to get started using them, and maybe you won't need to learn anything more.
m + an uppercase letter → set a mark at your cursor position
:marks → see all your current marks
' (single quote) + the letter → jump straight back to that spot
A few days ago, I uploaded a video featuring bright and colorful themes. Some of you asked me about this other type of themes, so here they are.
I love vibrant, high-contrast themes, but for day-to-day work, when I need to get things done without straining my eyes, these are the ones I use. You could say they're the themes I use the most, and the ones that help me focus better on the code.
I hope you enjoy them.
This is a showcase with themes that use vibrant colors, strong contrast, and eye-catching aesthetic. While some of them may not be the best choice for coding all day (your eyes might get tired) they are perfect for videos, live coding, tutorials, and demonstrations.

In this video, I showcase some non conventional programming fonts I discovered here and other corners of the internet. While most of these fonts aren't ideal for everyday coding, they're perfect for retro programming demos, hacker-style terminals, YouTube videos, or simply showing off an awesome-looking development setup.
Whether you're looking for a nostalgic pixel aesthetic, a cyberpunk vibe, or just something different from the usual coding fonts, you'll probably find a few new favorites here.
01 Departure Mono
02 Terminus
03 Cozette
04 Scientifica
05 Proggy clean nerd font
06 0xProto nerd font
07 Martian mono nerd font
08 Monaspace Radon
09 Victor mono nerd font
10 Tamsyn
I wanted to get my stuff done. I had too many TODOs spread across different projects.
So, instead of getting started, I procrastinated by creating a Neovim command to get a summary of all the TODOs in my projects.
This is what the command does:
I know I have to stop doing this, but no regrets.

Vim regexes are hard. I almost always try to avoid them or replace them with a macro. Recently, I've been using them more often, and they have started to feel more natural.
Another killer fact is that the speed of a regex is great so you can edit big text with no problem.
I leave you with 10 real-world examples of how I've been using Vim regex:
01 - Replace extra whitespaces
02 - Break line after period
03 - Markdown list to SQL Script
04 - Markdown list to HTML
05 - CSV phone numbers from text
06 - Log file to Csv
07 - Camel case to Snake case
08 - Upper case after period
09 - Html list to csv file
10 - Markdown TODO list from code

I'm learning Raylib. This is my first attempt at a Mandelbrot explorer. There are tons of very good implementations of this on the internet, and it is a very good exercise for learning Raylib. The best implementations use shaders.
In my case, to handle the zoom (the interesting part), I just decrease the step between points in the fractal. This can be improved in many ways, but I think it's a good start. I'm loving Raylib, but I'm considering switching to C++. I don't like the fact that I have to implement lists and vectors myself.

In this video, I showcase 10 Vim macro examples that I've used throughout my programming journey. Some of them are truly awesome!
I had a lot of fun programming this. It's the classic Matrix rain effect. I'm still learning, but I hope to make something as cool as the projects people post in this subreddit someday.
The best implementation for matrix rain is this:

And this is my humble implementation

I hate UI of Android/Visual Studio but I love their Search Everything feature.
This is my first attempt to have it in Neovim. I use ripgrep to search files and content in the current directory and I populate the quickfix list. I use a simple buffer for the user input.
Nothing fancy, just the methods from the neovim api and 100~ lines.

I was looking for a way to integrate Ripgrep into Neovim without using plugins, and I was quite surprised by how easy it is.

My repo:

Code:
local function ripgrep(search)
local result = vim.fn.systemlist("rg --vimgrep " .. search)
vim.fn.setqflist({}, "r", {
title = "Results",
lines = result
})
vim.cmd("copen")
end
vim.api.nvim_create_user_command("Rg", function(args)
ripgrep(args.args)
end,
{ nargs = 1 })

Hi, everyone! Im really enjoying the games/animations/simulations in this subreddit. So, I decided to give it a try to Raylib.

Just a quick tip helpful when you are starting with neovim
Add this to your config and you will have the exit option in the menu
vim.cmd([[amenu PopUp.Exit\ (q) :q<CR>]])

I created a small project to send commands from a mobile app to a Neovim server. I wanted to explore using Neovim as a server.
Do you see any practical applications for this?
