Gopls and the Rabbit Hole

gopls v0.9.5 hangs when visiting a buffer when running under eglot under Mac GUI for some reason. Downgrading gopls to v0.9.4 make it works under eglot again. Naturally, I would assume this was a regression with gopls. git bisect indicates that the first "bad" commit was https://github.com/golang/tools/commit/cd31eaad03d53a18fa4b5e25b94d0b65e7380349, which means it should fail since v0.8.2, but for some reason installing via go install golang.org/x/tools/gopls@vX.Y.Z worked up to v0.9.4, even with go 1.19, and even v0.9.5 works fine when running under LSP client (Sublime Text).

In an attempt to find out if this code path was indeed an issue, I cloned the latest commit and attempt to stub out gopls/internal/vulncheck. Fortunately, this particular code were already stubbed out for go version older than 1.18, so removing this code was easy:

diff --git a/gopls/internal/vulncheck/command

Setting Up Clojure on OS X

I spent a lot of time trying to find a pretty optimal (for me) setup for Clojure… at the same time I was trying to dive in and learn it. This is never optimal; you shouldn't be fighting the environment while trying to learn something.

I feel like I went through a lot of pain searching Google, StackOverflow, blogs, and other sites for random tidbits of information and instructions.

This is a comprehensive "what I learned and what I ended up doing" that will hopefully be of use to others and act as a journal for myself if I ever have to do it again. I want to be very step-by-step and explain what's happening (and why) at each step.

Step 1: Getting Clojure (1.3)

Setting up Vim as your Go IDE

Intro

I've been wanting to do a serious project in Go. One thing holding me back has been a my working environment. As a huge PyCharm user, I was hoping the Go IDE plugin for IntelliJ IDEA would fit my needs. However, it never felt quite right. After a previous experiment a few years ago using Vim, I knew how powerful it could be if I put in the time to make it so. Luckily there are plugins for almost anything you need to do with Go or what you would expect form and IDE. While this is no where near comprehensive, it will get you writing code, building and testing with the power you would expect from Vim.

Getting Started

I'm assuming you're coming with a clean slate. For me this was OSX so I used MacVim. There is nothing in my config files that assumes this is the case.
