beer is a programming language.

Most languages aim to provide strong features like

• concurrency.
• blazingly fast performance.
• confusing memory safety on steroids.
• A new package/framework/library/runtime every week.

Can't you write a project on a lazy Sunday afternoon, without worrying about the future ?

beer is a lighly brewed language, that aims to provide a simple and fun way to write code.

• The codebase is designed for beginner coders to understand and contribute.
• Aimed to be extensible and easy to hack on.
• Smartly documented with beautiful write-up and self-explanatory code.

• The syntax is not ambiguous and is easy to read.
• Looks beautiful and is fun to write.
• Errors don't scold you.

• Comes with a suite of tools to write, test and deploy code.
• Write, Test, Refactor quickly.

• You fall in love with coding.

a: 10 b: 20

if a > b { printf("a is greater than b") }

fn add(a, b) { ret a + b }

Call using

add(a:10, b:20)

fn something() { printf("something") } }`

;; this is a comment ;;; this is a docstring ;;; before a function it becomes a docstring

• number, combination of int and float.
• string, a sequence of characters.
• boolean, true or false.
• list, a sequence of elements.
• table.

• +, -, *, /, %.
• ==, !=, >, <, >=, <=.
• &&, ||, !.
• ++, --.

• Write a test anywhere.

• Just use test instead of fn.

test add { a: 10 b: 20 assert a + b == 30, "addition failed" }

• assert can test anything!

• A cask is a something like a package in other languages.

import math

• Export functions using cask keyword.

cask { ;; mention the functions you want to export ;; you can only export functions add, }

• Should be at the end of the file.
• A directory with a set of files becomes a cask, that can be imported with the directory name.
• A directory when run using beer run will find the main function and run it. It shouldn't be exported.

• Open a file with .b as extension and write code.
• Run code with beer run <filename>
• Generate a new project with beer create
• Test code with beer test.
