Kyori String distance and similarity metrics for JavaScript — Levenshtein, Damerau-Levenshtein, Hamming, Jaro-Winkler, and the Kyori ranking algorithm, every one implemented natively. The bundled Kyori Index turns a term list into a ready-made autocomplete backend.: Levenshtein, Damerau-Levenshtein, Hamming, Jaro-Winkler — all native
Kyori ranking folds case, accents, and hyphens, and survives typos
Kyori Index: load terms once, search() returns them scored, best first

WizJS A curated set of utilities for more maintainable everyday JavaScript — without becoming another lodash. Ports Python's itertools, functools, and collections to JS, with zero runtime dependencies.: Python stdlib in JS — 18 lazy itertools generators, functools, Counter, DefaultDict
BBTreeMap — an ordered map with lookups up to 2.75× faster than a classic B-tree
Import one area at a time — every area is its own package subpath
Zero runtime dependencies — nothing else comes along
Plain CommonJS, tested on Node

Practical UV CLI Moves a pip project to uv from any terminal: run npx @wizhut_tech/practical-uv convert in the project folder and requirements.txt becomes pyproject.toml and uv.lock. The same conversion as the Practical UV extension, without VS Code.: One command, nothing to install first: npx fetches it
Lists the exact commands and asks before running anything; --yes for scripts and pipelines
Development requirements go into uv's dev group, and no other files are added

json2jsonl A lightweight command-line tool to convert one or many JSON files into a single JSONL (JSON Lines) output. Pipe-friendly — output goes to stdout when no file is specified.: Batch-convert multiple JSON files in one command
Pipe output directly to grep, jq, or any Unix tool
Pre-built binaries for macOS (Intel & Apple Silicon), Linux, and Windows

trimmer A single-purpose command-line filter that reads stdin and writes it back without the leading and trailing whitespace. Trims the whole input by default, or every line individually with --lines.: Unicode-aware trimming — tabs, CRLF, NBSP, and the rest, not just spaces
--no-newline gives command substitution the exact value, with nothing clinging to it
Pre-built binaries for macOS, Linux, and Windows on both x86_64 and ARM

Practical UV Bring the power of uv — the blazing-fast Python package manager — directly into VS Code. Works with both pyproject.toml and requirements.txt: detect outdated dependencies and known vulnerabilities, convert pip projects to uv in one click, and run uv commands without leaving your editor.: Outdated dependency detection in pyproject.toml and requirements.txt with one-click upgrades
Known-vulnerability checks against the OSV advisory database — CVE, severity, and the version that fixes it
uv.lock resolves declared ranges to exact versions, so findings mean you are affected, not merely permitted
One-click conversion of requirements.txt projects to uv from the status bar
Interactive dependency dashboard with current vs. latest PyPI versions and Upgrade buttons
Quick-fix project version bumps and Python version picker (sourced from endoflife.date)
Run uv sync, add, and run from the VS Code command palette
