Debugging Go

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Extracting Emoji From Slack!

Slack doesn't provide an easy way to extract custom emoji from a team. (Especially teams with thousands of custom emoji) This Gist walks you through a relatively simple approach to get your emoji out.

If you're an admin of your own team, you can get the list of emoji directly using this API: https://api.slack.com/methods/emoji.list. Once you have it, skip to Step 3

HOWEVER! This gist is intended for people who don't have admin access, nor access tokens for using that list.

What is sync.Pool in golang and How to use it

sync.Pool (1/2)

Many Go libraries include custom thread-safe free lists, like this:

var objPool = make(chan *Object, 10)

func obj() *Object {

select {

	#!/usr/bin/env bash

	#File: tree2githubmd
	#Description: Convert output of unix tree utility to Github flavoured Markdown

	tree=$(tree -f --noreport --charset ascii $1 \|
	sed -e 's/\| \+/ /g' -e 's/[\|`]-\+/ /g' -e 's:\( \)\(\(.*/\)\([^/]\+\)\):\1[\4](\2):g')
	printf "# Code/Directory Structure:\n\n${tree}"

	# This demonstrates that, when using async/await, a crash in the task will crash the caller
	defmodule Tasker do
	def good(message) do
	IO.puts message
	end

	def bad(message) do
	IO.puts message
	raise "I'm BAD!"
	end

	When using http.Get(), is it really necessary to read the full response body just to close it later?

	[9:10]
	The docs keep saying `Caller should close resp.Body when done reading from it.` and I keep seeing code like this:
	```
	io.Copy(ioutil.Discard, resp.Body)
	resp.Body.Close()
	```

	" NeoBundle
	"
	if has('vim_starting')
	set runtimepath+=~/.nvim/bundle/neobundle.vim/
	endif
	call neobundle#begin(expand('~/.nvim/bundle'))
	NeoBundleFetch 'Shougo/neobundle.vim'

	" Completion
	NeoBundle 'Shougo/deoplete.nvim'

	(ns reagent-test.core
	(:require [reagent.core :as reagent :refer [atom]]
	[datascript :as d]
	[cljs-uuid-utils :as uuid]))

	([conn q]
	(bind conn q (atom nil)))
