CLI-GUIDELINES.md

A compact contract for CLIs that humans can use (good UX) and machines can trust (predictable behavior, stable output).

Use when designing, implementing, or reviewing command-line tools, especially CLIs that need reliable automation behavior, stable machine-readable output, safe mutation semantics, or good terminal UX.

How to Use This Document

When building or reviewing a CLI:

1. First classify it by capability/risk dimensions:

Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.

1. Combined type and variable/field declaration, inside a struct scope [https://godbolt.org/g/Rh94Go]

struct foo {
   struct bar {
 int x;

const Moment = require('moment')
const array = [{date:"2018-05-11"},{date:"2018-05-12"},{date:"2018-05-10"}]
const sortedArray  = array.sort((a,b) => new Moment(a.date).format('YYYYMMDD') - new Moment(b.date).format('YYYYMMDD'))
console.log(sortedArray)

Serverless plugin author's cheat sheet

This cheat sheet provides a detailed overview of the exposed lifecycle events and available commands (and entrypoints) of the Serverless framework, that can be hooked by plugins (internal and external ones). The document is structured by the commands invoked by the user.

Lifecycle events are shown as the globally available outer events (all providers) and sub lifecycle events that are provider specific in the called order. Currently only the AWS provider is shown. If you have information about the other provider,

function getLambdaEventSource(event) {
    if (event.Records && event.Records[0].cf) return 'isCloudfront';

    if (event.configRuleId && event.configRuleName && event.configRuleArn) return 'isAwsConfig';

    if (event.Records && (event.Records[0].eventSource === 'aws:codecommit')) return 'isCodeCommit';

    if (event.authorizationToken === "incoming-client-token") return 'isApiGatewayAuthorizer';

    if (event.StackId && event.RequestType && event.ResourceType) return 'isCloudFormation';
