Minimock: A Tool to Generate Mocks from Interface Declarations — Generates statically typed mocks and helpers, is fully integrated with the testing package, and supports generics.

Oscar: An Open-Source Contributor Agent Architecture — As Russ steps away as Go tech lead, he’s stepping into more work on Oscar, an AI agent system to help maintain open-source projects. The first bot, Gaby, is already up and running on Go’s issue tracker, with more to come.

What's the Best Static Analysis Tool for Go? — Static analysis can be a valuable part of an app’s quality toolchain, run by both developers and pipelines. But there are many options, official and otherwise, so which to choose? The answer is (kinda) all of them…?

Did You Know About Instruments? — Instruments is a macOS app that allows you to create various traces and profiles of running applications. It offers quite the toolset, as indicated by Thorsten’s palpable enthusiasm.

Implementing HTTP/0.9 from Scratch — The first instalment of a “HTTP from Scratch” series digging into the history of the protocol underpinning the Web.

approf: A Native macOS App for pprof — An app experience for viewing the results from pprof profiling that includes drag/drop, reordering, light/dark mode, and saved sessions.

Glamour: Stylesheet-based Markdown Rendering for Your CLI Apps — Glamour lets you render simple Markdown from your app but then have styles applied to it so that it looks more colorful and elegant once it lands in the terminal. Another great piece of work from the folks at Charm.

mimetype: Library for Detecting MIME Types and Extensions — Supporting 173 different types, you pass in binary data, a data stream or filename and, hopefully, find out what type of data you’re working with.

go-sqlbuilder: A Flexible SQL String Builder Library — Originally focused on MySQL and Postgres, it now supports SQL Server, SQLite, CQL, and more, too. Lets you use structs as a ‘light weight ORM’, and now also supports Common Table Expression and ILIKE.

Cogent Core: A New GUI Framework for Go — A new GUI framework with a “code once and run everywhere” promise for multiple platforms. It aims to be simpler to use than Gio and more powerful than Fyne. Curiously, Cogent’s web site itself is built in the framework and compiled to WASM to work on the Web. There’s also ▶️ a quick screencast pitching you...

Go Features by Version (or What's in Which Go) — A list of features and the versions in which they first appeared. Proof, if any were needed, that the progress made to Go isn't slowing down. (And if you want to get up to speed with Go 1.23, here are the notes for you.)

Build Your Own SMTP Server in Go — The actual code here isn’t low level, but it's a good practical guide to some of the technologies around sending e-mail, like SMTP, DKIM, and SPF. The go-smtp library ultimately does the heavy lifting.

What’s New in Go 1.23: Iterators and reflect.Value.Seq — Carlana explains four of the functions around generic custom iteration that she proposed, comparing the new code to something she wrote ten(!) years ago using channels. If 2022 was all about generics, is 2024 the year of iterators?

Learn Go with Tests: A Refactoring Checklist — The popular Learn Go with Tests guide gains a new chapter that gets you thinking about refactoring, when it makes sense to do it, and some of the basic techniques.

The Union of Finite Automata, Explained — Tim found existing explanations to be overly academic, so set out to explain the concept with a little Go.

Ollama 0.3: Quickly Run Large Language Models — Ollama is an increasingly significant Go-powered tool in the LLM world (that uses llama.cpp behind the scenes) that makes it easy to run large language models. Recent releases have added concurrency, Llama 3.1 support, and, now, tool calling.

betteralign 0.5: Make Your Programs Use Less Memory.. Maybe — A tool to detect structs that could use less memory. It’s a fork of Go’s fieldalignment tool that skips generated or test files, skips specially marked structs or those with anonymous fields, doesn’t drop comments, and similar DX enhancements.

Editor: A Source Code Editor in Pure Go — Curiously billing itself as a “simple but advanced source code editor”, it works on Linux, Windows and macOS (under X server) and certainly has that old school Unix vibe going on. Clearly a serious labor of love after some seven years of development.
