Neofetch for Git repositories

o2sh — Sun, 08 Nov 2020 14:05:36 +0000

Here is a fun little tool you might enjoy. It doesn't do much other than displaying a bunch of info about your Git Repository along side an ASCII logo of the dominant language.

Onefetch supports more than 50 different programming languages.

Written fully in Rust, it implements Kitty, Sixel and iTerm image protocol to render graphics (images) on supported terminals --> More info here

I would love some feedback :)

Command-line Git information tool

Command-line Git information tool written in Rust

Onefetch is a command-line Git information tool written in Rust that displays project information and code statistics for a local Git repository directly to your terminal. The tool is completely offline - no network access is required.

By default, the repo's information is displayed alongside the dominant language's logo, but you can further configure onefetch to instead use an image - on supported terminals -, a text input or nothing at all.

It automatically detects open source licenses from texts and provides the user with valuable information like code distribution, pending changes, number of dependencies (by package manager), top contributors (by number of commits), size on disk, creation date, LOC (lines of code), etc.

Onefetch can be configured via command-line flags to display exactly…

What is the Coolest Program ever?

o2sh — Mon, 27 May 2019 12:43:31 +0000

Came to share a pretty sweet initiative from /g/ (4chan board focused on technology).

The idea was to have a site where people could share and discuss about the coolest pieces of code out there.

You can access the App by clicking here.

The site was launched last friday, so there isn't much content yet. Contributions are more than welcomed.

Voilà, show some love will u ❤️

add one

o2sh — Tue, 06 Nov 2018 21:20:46 +0000

Here is a little program I wrote in Rust that allows you to add one to any number

o2sh / add-one

adds one to a number

add-one

Returns n + 1.

Example

use add_one::add_one;

fn main() {
    let mut bytes = Vec::new();

    match add_one("123".as_bytes(), &mut bytes) {
        Ok(()) => println!("{}", std::str::from_utf8(&bytes).unwrap()),
        Err(e) => {
            eprintln!("Error: {}", e);
        }
    }
}

cargo install add-one
add-one 12
13

The idea is pretty simple. Indeed, since incrementing a number leaves most of it unchanged, it's much faster to work on the decimal digits itself.

As a consequence, after breaking the input into a list of digits, we just have to increment or decrement (in case of negative input) the last number.

Not so fast...

What if the number has trailing nines for positive inputs or trailing zeros for negative numbers ?

Well, if the number has trailing nines (e.g.: 7561325999) or trailing zeros (e.g.: -1645000), we just need to increment the last "non-nine" digit (or decrement the last "non-zero" digit) and switch the nines into zeros and zeros into nines (for negative inputs).

And, in the case of floating point inputs (e.g.: 15691.12313) we simply ignore the decimal part and apply the previous rule to the integer part.

Unless...

...the input belongs to ]-1,0[ (e.g.: -0.2 + 1 = 0,8 (not 1.2!)). In which case, we have to give it a special treatment.

Thanks for reading ! :)

New sorting algorithm: mkdir sort

o2sh — Wed, 29 Aug 2018 14:15:50 +0000

A little sorting algorithm I made just for fun.

#!/bin/bash
function f() {
    echo $(eval printf 'g/%.0s' {1.."$1"})"$1" | xargs mkdir -p
}

while [ -n "$1" ]
do
    f "$1"
    shift
done

find . -type d | sed 's#.*/##' | grep -v g

#./mkdirsort.sh 9 2 7 4 6

It's like a "b-tree sort" using the FS

o2sh / mkdir-sort

sorting algorithm using mkdir

mkdir-sort

sorting algorithm using mkdir

Example

$ mkdir wkdir
$ cd wkdir
$ ./mkdirsort.sh 9 2 7 4 6
$ rm -rf g/
