uwuify

fastest text uwuifier in the west

transforms

Hey, I think I really love you. Do you want a headpat?

into

hey, (ꈍᴗꈍ) i think i weawwy wuv you. ^•ﻌ•^ do y-you want a headpat?

there's an uwu'd version of this readme

faq

what?

u want large amounts of text uwu'd in a smol amount of time

where?

ur computer, if it has a recent x86 cpu (intel, amd) that supports sse4.1

why?

why not?

how?

tldr: 128-bit simd vectorization plus some big brain algos

after hours of research, i've finally understood the essence of uwu'd text

there are a few transformations:

replace some words (small -> smol, etc.)
nya-ify (eg. naruhodo -> nyaruhodo)
replace l and r with w
stutter sometimes (hi -> h-hi)
add a text emoji after punctuation (,, ., or !) sometimes

these transformation passes take advantage of sse4.1 vector intrinsics to process 16 bytes at once. for string searching, i'm using a custom simd implementation of the bitap algorithm for matching against multiple strings. for random number generation, i'm using XorShift32. for most character-level detection within simd registers, its all masking and shifting to simulate basic state machines in parallel

multithreading is supported, so u can exploit all of ur cpu cores for the noble goal of uwu-ing massive amounts of text

utf-8 is handled elegantly by simply ignoring non-ascii characters in the input

unfortunately, due to both simd parallelism and multithreading, some words may not be fully uwu'd if they were lucky enough to cross the boundary of a simd vector or a thread's buffer. they won't escape so easily next time

ok i want uwu'd text, how do i run this myself?

install command-line tool

install rust: run curl https://sh.rustup.rs -sSf | sh on unix, or go here for more options
run cargo install uwuify
run uwuify which will read from stdin and output to stdout. make sure u press ctrl + d (unix) or ctrl + z and enter (windows) after u type stuff in stdin to send an EOF

if you are having trouble running uwuify, make sure you have ~/.cargo/bin in your $PATH

it is possible to read and write from files by specifying the input file and output file, in that order. u can use --help for more info. pass in -v for timings

this is on crates.io here

include as library

put uwuify = "^0.2" under [dependencies] in your Cargo.toml file
the library is called uwuifier (slightly different from the name of the binary!) use it like so:

use uwuifier::uwuify_str_sse;
assert_eq!(uwuify_str_sse("hello world"), "hewwo wowwd");

documentation is here

build from this repo

click for more info

install rust
run git clone https://github.com/Daniel-Liu-c0deb0t/uwu.git && cd uwu
run cargo run --release

testing

run cargo test

benchmarking

run mkdir test && cd test

warning: large files of 100mb and 1gb, respectively

run curl -OL http://mattmahoney.net/dc/enwik8.zip && unzip enwik8.zip
run curl -OL http://mattmahoney.net/dc/enwik9.zip && unzip enwik9.zip
run cd .. && ./bench.sh

i don't believe that this is fast. i need proof!!1!

tldr: can be almost as fast as simply copying a file

raw numbers from running ./bench.sh on a 2019 macbook pro with eight intel 2.3 ghz i9 cpus and 16 gb of ram are shown below. the dataset used is the first 100mb and first 1gb of english wikipedia. the same dataset is used for the hutter prize for text compression

//TODO: compare with other tools

why isn't this readme uwu'd?

so its readable

if u happen to find uwu'd text more readable, there's always an uwu'd version

ok but why aren't there any settings i can change?!1?!!1

free will is an illusion

wtf this is so unprofessional how are u gonna get hired at faang now?!

don't worry, i've got u covered

Title: uwu is all you need

Abstract

Recent advances in computing have made strides in parallelization, whether at a fine-grained level with SIMD instructions, or at a high level with multiple CPU cores. Taking advantage of these advances, we explore how the useful task of performing an uwu transformation on plain text can be scaled up to large input datasets. Our contributions in this paper are threefold: first, we present, to our knowledge, the first rigorous definition of uwu'd text. Second, we show our novel algorithms for uwu-ing text, exploiting vectorization and multithreading features that are available on modern CPUs. Finally, we provide rigorous experimental results that show how our implementation could be the "fastest in the west." In our benchmarks, we observe that our implementation was almost as a fast as a simple file copy, which is entirely IO-bound. We believe our work has potential applications in various domains, from data augmentation and text preprocessing for natural language processing, to giving authors the ability to convey potentially wholesome or cute meme messages with minimal time and effort.

// TODO: write paper

// TODO: write more about machine learning so i get funding

ok i need to use this for something and i need the license info
