My Review of 2020

The 2020 year has been hard almost for everyone due to the pandemic. My year was almost alright, but then my family also got infected with COVID-19 recently. However, we luckily fought through it and now we are safe.

I hope everyone's safe and I pray for those who are going through this tough time. Since I was always at home, I was over-productive this year as I had a lot of time to learn and make stuff. I believed that such an opportunity to improve will never come again, so I made the best use of it.

And as 2020 is about to end soon, these are the things I accomplished this year:


  • My account articles have passed more than 100K views in less than one year of creation!
  • I made small 5 projects and learned a lot of things and met a lot of people who helped me to implement those features! I would like to thank them very much ^-^
  • My GoLang library: Box Cli Maker has 100+ stars in just 8 months!!
  • V By Example has also 100+ stars :)
  • I have done a total of 200 Pull Requests in my whole life.
  • I have completed Hacktoberfest 2020 and I did around 7 PRs this time during October because I was busy that time with other things!
  • I learnt more about V's internal compiler and started to implement small features and fix bugs and issues slowly and step by step!
  • I had started taking part in discussions of Python's Pattern Matching syntax and was against the favour of using _ for denoting else case in match syntax as it would be inconsistent and wouldn't make it Pythonic anymore. I tried giving some issues and I got acknowledged from them. Though my proposal was rejected as I wasn't a part of them.
  • I got some "job offers" but I feel those were scams so I rejected them as who can hire someone like that? I think it's still an achievement as people are coming to me xD
  • I made a Github Profile in such a unique style that others liked and copied it.
  • Opened several issues in Golang, V and Deno etc.
  • Became a collaborator of Bhupesh-V/30-seconds-of-cpp.
  • Got 90+ followers on GitHub.
  • My proposal for Windows Terminal got accepted!

  • All variate functions possible.
  • Generate random int and string with ease.
  • range functions for int and f32.
  • Array functions like shuffle, choose, sample etc.
  • Makes life easier sorta
  • Many more features coming soon!


  • Via git clone
    • git clone
  • Via v install
    • v install random
  • Via vpkg
    • vpkg install random

struct Triangular {
        low  f32 = 1.0
        high f32 = 1.0
        mode int = 1

  • CLI Badges

CLI Badges

Generate Badges for your CLI.

deno land deno version GitHub release CI

NOTE: It is recommended to update pre-exisiting versions of this module to ^v0.1.0 as there are many breaking changes from this release in the API.


  • Make Beautiful Badges for CLI 🤩
  • Works across all terminals 🦄
  • Link support 🔗
  • Variety of colors to choose from 🎨
  • Written in TS with Deno 🦕

Warning ⚠️: If your terminal has a custom theme then the colors will blend according to your configuration which can cause unwanted results.


Simple Example

Showcases failed, success and skipped badge on the terminal

import { badge } from "";
console.log(badge("failed", "2", { msgBg: "red" }));

console.log(badge("success", "2", { msgBg: "green" }));

console.log(badge("skipped", "2"

  • range

GitHub logo Delta456 / range

Functionality of Python's range() in V


Numeric ranges in V.


  • a..b in V can only be in increasing order and not in negative order.
  • Lacks inbuilt step which most people need or want.
  • No support for float type.
  • Solution for vlang/v#5944.


  • Make range easily
  • Make ranges for int and f32
  • Positive as well as negative support!
  • No need to write the whole for loop! (this maybe slower than the normal one)
  • Use range for functional programming
  • Support iterators. Long ranges without high memory allocation.
  • Half open-open ranges [from,to]


  • Via git clone
    • git clone
  • Via v install
    • v install Delta456.range
  • Via vpkg
    • vpkg install range


Use an iterator if you need a large range but don't want to allocate space in memory for all numbers in the range.

import delta456.range
mut iter := range.to_iterator(from: 0, to: 1000000, step: 2)
for v in iter

  • ASCII Robot

ASCII Robot Generator in V


  • Via git clone
    • git clone
  • Via v install
    • v install ascii_robot
  • Via vpkg
    • vpkg install ascii_robot


  • random_id() returns a random 5 digit hex number in string.

  • generate(string) returns a string optional. string returns random made ASCII bot depending upon the 5 digit number.

  • must_generate(string) is same as generate() but returns an empty string if the hex number provided is not valid.

  • random_robot() returns a random ASCII robot.

In main.v

import delta456.ascii_robot as robot
import rand
fn main() {
    rand.seed([u32(42), 0]) // or use your seeder

    for i := 0; i < 5; i++ {
Enter fullscreen mode Exit fullscreen mode

Bot Types

Total ASCII Robot Types possible:
