📚 Awesome cheatsheets for popular programming languages, frameworks and development tools. They include everything you should know in one single file.

🤔 Why Awesome-Cheatsheets?

I usually make a cheat sheet when I want to improve my skills in a programming language, a framework or a development tool. I started doing these kinds of things a long time ago on Gist. To better keep track of the history and to let people contribute, I re-organized all of them into this single repository. Most of the content is coming from official documentation and some books I have read.

Feel free to take a look. You might learn new things. They have been designed to provide a quick way to assess your knowledge and to save you time.

Awesome Cgeatsheets

Code

Module / require example

https://github.com/LeCoupa/awesome-cheatsheets/blob/master/backend/node.js#L77 should be more like

const foo = require('./subfolder/foo.js')
console.log('foo "%s"', foo) // "foo"

// now grab the "module" wrapper around './foo.js'
const fooModule = require.cache[require.resolve('./subfolder/foo.js')]

console.log('foo module', fooModule)
// load module ./bar relative to ./foo
// real path to './bar' is './subfolder/bar'
const bar = fooModule.require('./bar')
console.log('bar "%s"', bar) // "bar"

Cheatsheet C

I think it would be wonderful if you create a cheat sheet for C.

Thank you.

Best regards.

I've been doing the same thing for some time now.
I've also written a small Sublime Text plugin to make things easier.
Maybe you guys could so something similar. Cheers.

JavaScript is NOT a functional language

In languages section, there are 3 different categories: command line interface (that is strange naming too), imperative and functional. The reason I am writing the issue is that, JavaScript is clearly imperative, not functional language. Like Java or Go. There are no Pattern Matching, Persistent Data Structures (at least yet, there's a ECMAScript proposal) and Algebraic Data Types.

Also in JavaScript if structure is a statement, not expression. That simply must be a imperative programming language. In functional languages if's are expressions.

Only functional features, that Javascript got at the present, are patterns like map or impure lambda expression alternatives called "arrow functions". Java got them too. They have really weak functional paradigmads.

Just move JavaScript to "imperative" section and don't change terms.

Cheat sheet for Python

I would like to add cheat sheet for python,
Please, assign the task for me.

Missing in Vim cheatsheet: autocompletion (ctrl-p, ctrl-n)

Missing backward-looking and forward-looking autocompletion (ctrl-p, ctrl-n).

Convert references of other installables to links wherever possible

For example, in this file.
It would be better to write Better comments instead of Better comments.

[Angular] Incorrect syntax for ngSwitchCase

Seen:

// Conditionally swaps the contents of the div by selecting one of the embedded templates based on 
// the current value of conditionExpression.
// <div [ngSwitch]="conditionExpression">
// <ng-template [ngSwitchCase]="case1Exp">...</ng-template>
// <ng-template ngSwitchCase="case2LiteralString">...</ng-template>
// <ng-template ngSwitchDefault>...</ng-template>
// </div>  

At:

awesome-cheatsheets/frontend/angular.js

Line 140 in f0d2664

// Conditionally swaps the contents of the div by selecting one of the embedded templates based on

Should be:

// Conditionally swaps the contents of the div by selecting one of the containers based on 
// the current value of conditionExpression.
// <div [ngSwitch]="conditionExpression">
//   <ng-container *ngSwitchCase="case1Exp">...</ng-container>
//   <ng-container *ngSwitchCase="'case2LiteralString'">...</ng-container>
//   <ng-container *ngSwitchDefault>...</ng-container>
// </div>  

I also replaced templates with containers (but could be real HTML tags) because using templates this way seems odd.

Cannot use 20 (type int) as type *int in assignment

pointer = 20

Should be

*pointer = 20

VIM - addition to Visual mode

Selection to matching parenthesis
v% if the cursor is on the starting/ending parenthesis

Selection to matching curly brace
vi{

Select text between quotes:
vi" for double quotes
vi' for single quotes

VIM: ddkp -> ddkP

Swap current line with previous is ddkP as ddkp will just insert at the original position.

Implement this Haskell cheatsheet.

Found this gem today. http://cheatsheet.codeslower.com/CheatSheet.pdf

Would love to see a minified version of this pdf for the Haskell programming language.

bash.sh

Basics

Add Assembly Cheatsheets

I guess it is good to add assembly cheatsheets maybe?

Angular cheat sheet

Create a cheat sheet for angular 4

add equivalent

awesome-cheatsheets/languages/bash.sh

Line 194 in 016c07a

${varname:-word} # if varname exists and isn't null, return its value; otherwise return word

${varname:word} is equivalent to ${varname:-word}

Convert cheatsheet documents to markdown (md) files

I think it would be better to have the cheatsheet documents as .md files instead of the corresponding language files.

It would be more readable and it would be able to present the documents in a better format.

Add Bootstrap

Hi.

You have great cheatsheets. But there is no Bootstrap!

I think it is better to add Bootstrap. I can help you in that case.

Tnx.
Amir.
