Show HN: Lstr – A modern, interactive tree command written in Rust (Score: 150+ in 10 hours)

Hi HN,
(First time poster!)
I'm the author of `lstr`. I've always loved the classic Linux `tree` command for its simplicity, but I often found myself wanting more modern features like interactivity and Git integration. So, I decided to build my own version in Rust with a philosophy of being fast, minimalist, and interactive. It was also an excuse to help learn more about Rust\!
Here's a quick look at the interactive mode:
https://raw.githubusercontent.com/bgreenwell/lstr/main/asset...
I've just released v0.2.0 with some features I think this community might find useful:
* **Interactive TUI Mode:** You can launch it with `lstr interactive`. It allows for keyboard-driven navigation, expanding/collapsing directories, and opening files in your default editor.
* **Git Status Integration:** Using the `-G` flag, `lstr` will show the Git status of every file and directory right in the tree output.
* **Shell Integration:** This is my favorite feature. In interactive mode, you can press `Ctrl+s` to quit and have `lstr` print the selected path to stdout. This lets you pipe it into other commands or use it as a visual `cd`. For example, you can add this function to your `.bashrc`/`.zshrc`:
```bash
lcd() {
local selected_path
selected_path="$(lstr interactive -gG)"
if [[ -n "$selected_path" && -d "$selected_path" ]]; then
cd "$selected_path"
fi
}
```
Then just run `lcd` to visually pick a directory and jump to it.

Show HN: I recreated 90s Mode X demoscene effects in JavaScript and Canvas (Score: 152+ in 10 hours)
Link: https://readhacker.news/s/6weU5
Comments: https://readhacker.news/c/6weU5
After 25 years of writing software, I was feeling nostalgic for the kinds of things that got me into programming in the first place: the old DOS demoscene. I spent a weekend seeing if I could recapture some of that INT 13H VGA magic using today's web tech, but with the old-school constraints of doing it from scratch.
The result is this portfolio of ten classic effects running in a single HTML file. It's all vanilla JavaScript writing to a <canvas> element, with no external libraries. It was a fun challenge to implement things like:
* The color palette cycling and smooth fading in the Plasma demo.
* The buffer-averaging algorithm for the Fire effect to make the flames feel more natural.
* The distance-based texture crossfading in the Tunnel to create the illusion of flying through different sections.
* A 2D scalar field for the Metaballs to calculate the surface normals for that classic blended, metallic look (I did the best I could with the given constraints).
It was a great exercise in getting back to first principles and a reminder of how much those early demo programmers could accomplish with so little. I hope it brings back some good memories for others who grew up with this stuff.
I'd love to hear about your favorite classic demos or if there are any other iconic effects you think would be a fun challenge to add.
Cheers!
