tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

First let's check something.

brew info postgresql

The top of what gets printed as a result is the most important:

import test from 'tape';

test('A passing test', (assert) => {

  assert.pass('This test will pass.');

  assert.end();
});

test('Assertions with tape.', (assert) => {

ericelliott

import test from 'tape';

const before = test;
const after = test;

// beforeEach/afterEach rely on shared state.
// That's a big anti-pattern for testing.

// It's also silly to run something before and after
// ever test -- many of your tests won't need it.

ericelliott

test('Greet World', (assert) => new Promise((resolve) => {
  assert.equal(hello('World'), 'Hello, World!');

  setTimeout(() => {
    // do some async stuff
    resolve();
  }, 10);
}));
