// Package main is a sample macOS-app-bundling program to demonstrate how to | |
// automate the process described in this tutorial: | |
// | |
// https://medium.com/@mattholt/packaging-a-go-application-for-macos-f7084b00f6b5 | |
// | |
// Bundling the .app is the first thing it does, and creating the DMG is the | |
// second. Making the DMG is optional, and is only done if you provide | |
// the template DMG file, which you have to create beforehand. | |
// | |
// Example use: |
package main | |
import ( | |
"context" | |
"fmt" | |
"log" | |
"net/http" | |
"os" | |
"os/signal" | |

This gist is based on the information available at golang/dep, only slightly more terse and annotated with a few notes and links primarily for my own personal benefit. It's public in case this information is helpful to anyone else as well.
I initially advocated Glide for my team and then, more recently, vndr. I've also taken the approach of exerting direct control over what goes into vendor/
in my Dockerfiles, and also work from
isolated GOPATH environments on my system per project to ensure that dependencies are explicitly found under vendor/
.
At the end of the day, vendoring (and committing vendor/
) is about being in control of your dependencies and being able to achieve reproducible builds. While you can achieve this manually, things that are nice to have in a vendoring tool include:

#define NUM_LEDS 60 | |
#define DATA_PIN 3 | |
CRGB leds[NUM_LEDS]; | |
uint8_t hue = 0; | |

FastLED.addLeds<WS2812B, DATA_PIN, RGB>(leds, NUM_LEDS); |

throw new TypeError("Can not call static abstract method foo."); | |
} else if (this.foo === Abstract.foo) { | |
// Error Type 3. The child has not implemented this method. | |
throw new TypeError("Please implement static abstract method foo."); |

// A minimal polyfill for copying text to clipboard that works most of the time in most capable browsers. | |
// Note that: | |
// - You may not need this. `navigator.clipboard.writeText()` works directly in all modern browsers as of 2020. | |
// - In Edge, this may call `resolve()` even if copying failed. | |
// - In Safari, this may fail if there is nothing selected on the page. | |
// See https://github.com/lgarron/clipboard-polyfill for a more robust solution. | |
