Optimize Toolset

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.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

anvil-sol

v0.4.0

Published

Anvil — Anchor → Pinocchio/Native/Quasar transpiler. Drop-in CLI that converts Anchor source into a cargo-buildable project in three target Rust dialects, all from a single typed IR with deterministic emit + validator + portability lint.

Readme

anvil-sol

Anchor → Pinocchio / Native / Quasar transpiler. Pipe Anchor source through anvil and get a cargo-buildable project in three target Rust dialects, all from a single typed IR.

Install

Requires Bun ≥ 1.0:

# One-liner install for bun (skip if already installed)
curl -fsSL https://bun.sh/install | bash

# Install anvil-sol globally
bun install -g anvil-sol

Or run without installing:

bunx anvil-sol compile program.rs --target pinocchio

Quickstart

# Transpile an Anchor file to a cargo-buildable Pinocchio project
anvil compile program.rs --target pinocchio --output ./out
cd ./out && cargo build

# Or to native solana-program
anvil compile program.rs --target native --output ./out

# Inspect the IR
anvil parse program.rs --json

# Portability scorecard against a target
anvil lint program.rs --target pinocchio

Commands

anvil compile    parse → emit → validate → write project scaffold
anvil parse      Anchor source → IR (pretty or --json)
anvil validate   parse → emit → surface validator issues
anvil lint       portability scorecard (ready / review / blocker)
anvil bench      per-instruction CU comparison
anvil snapshot   capture/compare CU snapshots for CI
anvil diff       diff two IRs / programs
anvil migrate    Anchor v1.0 Migration<From, To> codegen + safety analysis

anvil migrate (NEW in 0.3)

# Compare two account layouts and emit a safety verdict
# (exit 0 = safe / exit 2 = unsafe; CI-friendly)
anvil migrate diff old-layout.json new-layout.json

# Generate the .migrate() body — lossless deterministic Rust for safe
# diffs, TODO-marked skeleton for unsafe ones with each unsafe change
# explained inline.
anvil migrate codegen old-layout.json new-layout.json --output migration.rs

See cli/migrate/examples/README.md for the layout-file format and three demo fixtures (safe + unsafe).

Each command supports --help.

Targets

| Target | Status | |---|---| | pinocchio | Hero target. 21+ MUST_PASS cargo-build regression gates. | | native (solana-program) | Production-ready reference. 21+ MUST_PASS gates. | | quasar | Experimental. No cargo-build coverage; some CPIs emit TODO stubs. |

Why

Anchor brought framework velocity to launching Solana programs. The 95% of a program's lifetime AFTER launch — CU optimization, account migrations, performance regressions — has no cohesive tooling. Anvil targets the post-launch lifecycle: compile (Anchor → leaner runtimes), with bench and migrate shipping next.
