Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

Emacs packages, features, files, layers, extensions, auto-loading, require, provide, use-package… All these terms getting you confused? Let’s clear up a few things.

Files

Emacs files contains code that can be evaluated. When evaluated, the functions, macros and modes defined in that file become available to the current Emacs session. Henceforth, this will be termed as loading a file.

One major problem is to ensure that all the correct files are loaded, and in the

Example

Run this and you will get an error related to being unable to relative import:

python example.py

Add the following chunk to your existing ISC dhcpd.conf file.

if exists user-class and ( option user-class = "iPXE" ) {
    filename "http://boot.smidsrod.lan/boot.ipxe";
}
else {
    filename "undionly.kpxe";
}

I am trying to do relative imports in Python

In Ruby, I can just

require '../puppies.rb'

But Python gets all weird when I try something similar.

My structure looks like this:

	(defun $magit-status-in-dir (dir)
	"limit magit status to directory"
	(interactive "D")
	(require 'magit)
	(let* ((root (vc-git-root dir))
	(dir (list (file-relative-name dir root)))
	(magit-status-mode-hook (cons (lambda () (setq-local magit-diff-section-file-args dir))
	magit-status-mode-hook)))
	(magit-status-internal root)))

	open Unix;
	open Printf;
	open Sys;
	open ExtUnix.All;
	open Thread;
	open CCBlockingQueue;
	open CCTimer;
