Together with

Log: A Minimal, Colorful Go Logging Library — A library from the same folks who brought us Bubble Tea and Gum so you know it’s from a good place. It provides “customizable colorful human readable logging with batteries included.”

Charm

All Your Comparable Types — The introduction of generics was bound to create edge cases. One is described here around interface implementation vs. constraint satisfaction. “As we’ll see in a bit, in Go 1.20 constraint satisfaction is not quite constraint implementation anymore.”

Robert Griesemer

Type Embedding: Go's Fake 'Inheritance' — Inspired by a “Keep Your Java Out of My Go” Reddit post, Zach shows how leaning too hard on object oriented ideas can cause hard-to-track-down bugs. But if you’re probably going to do it anyway.. read this to help debug later.

Zach Musgrave (DoltHub)

If you're curious, the not-particularly-edifying Reddit post that inspired the above was 'How to deal with Java developers polluting the Go code?'

IN BRIEF:

▶️ A developer explains how he picked up a $3,133.70 bounty for finding a XSS vulnerability in Go's x/net/html package. There's a code example of the problem and the resulting patch.
Generics have been in Go for roughly a year now, so 🐦 what have you been using them for, asks Kelsey Hightower?
Brandur Leach has some findings from six months of running govulncheck in CI.

go test and Parallelism — “Because I feel the concurrency behavior of go test is non-obvious .. I wanted to write something up here.”

Bryce Neal

How to Publish Go Binaries with Goreleaser — Goreleaser is a helpful tool if you need to cross-compile and publish binaries for multiple architectures, different operating systems, package managers, etc.

Rexford A Nyarko

Partially-Implemented Interfaces — When you just want to implement one or two methods … but be careful.

Preslav Rachev

Securely Deploy Kubernetes Clusters with GitHub Actions — Managing identity for Kubernetes & CI/CD workflows relies on dated security mechanisms, learn more in our new episode.

🛠 Code & Tools

Opossum: A Basic Web Browser Written in Go — A fun project, though you might need to have (or set up) a Plan 9-derived OS to get it running (though someone claims success on macOS). As user liotier said on Hacker News, though: “any sufficiently brave or delusional soul that ventures into even the most rudimentary web browser development is a hero to me”.

Philip Silva

Gin 1.9: A Fast HTTP Web Framework — We don’t often link to Gin because a) it doesn’t often get big updates, and b) it’s hugely popular and you probably use it already ;-) If you do, v1.9 is out, and if you don’t, it’s worth being on your radar.

Soft Serve: A Self-Hostable Git Server — Soft is configurable via git itself and comes with a nice terminal UI (TUI). Another interesting release from the Charm project.

Charm

koanf: Configuration Management Library — Support for JSON, TOML, YAML, env, command line, file, S3 etc. Alternative to Viper.

Kailash Nadh

VHS 0.3: The 'Home Video Recorder' for Your CLI — A tool plus scripting language for performing actions on the terminal which are then recorded into an animated GIF (or an MP4, webm file, or series of PNG frames). “Write terminal GIFs as code for integration testing and demoing your CLI tools.” v0.3 adds support for hosting said GIFs on Charm’s own vhs.charm․sh service.

Charm

♣️ Solitaire's the only game in town..

Solitaire TUI: Klondike Solitaire on the Terminal — If you, like me, ~~wasted~~spent much time in Windows 3.x playing the solitaire game, this Bubble Tea-powered creation (THAT'S THE FINAL CHARM PROJECT THIS WEEK!) might appeal to you now in 2023 too. Bonus points to anyone who can file a pull request to add the Windows-style ending animation ;-)
