I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

@joyanhui/pi-ext-bar-cursor

A pi extension that replaces the default block (reverse-video) cursor with a vertical bar using the terminal's native hardware cursor shape.

Features

Vertical bar cursor — uses DECSCUSR (\x1b[6 q) to tell the terminal to show a steady vertical bar
Block cursor removal — strips pi's fake block cursor (reverse-video \x1b[7m) so the hardware bar cursor is visible
Zero text shift — cursor width is preserved exactly, no crashes or text movement
IME compatible — preserves CURSOR_MARKER for IME candidate-window placement

Installation

pi install npm:@joyanhui/pi-ext-bar-cursor

Or for a single session:

pi -e npm:@joyanhui/pi-ext-bar-cursor

Requirements

pi coding agent (v0.x+)
showHardwareCursor: true in pi's settings.json

Usage

Once installed, the extension activates automatically on every session start. No commands or shortcuts needed.

If you're not using a terminal emulator that supports DECSCUSR (the \x1b[6 q sequence), you may need to check your terminal's cursor shape support.

How it works

On session_start, sends \x1b[6 q (DECSCUSR) to set a steady vertical bar cursor
Overrides pi's editor component to strip the reverse-video block cursor from each rendered line
The hardware bar cursor shows through unobstructed
