A lighly brewed programming language

beer

beer is a programming language.

inspiration

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.

features

beautiful codebase

• 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.

expressive syntax

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

batteries included

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

fun

• You fall in love with coding.

syntax

variables

a: 10 b: 20

control flow

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

functions

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

Call using

add(a:10, b:20)

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

comments

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

data types

• number, combination of int and float.
• string, a sequence of characters.

• table.

operators

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

tests

• 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!

cask

• 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 bart run will find the main function and run it. It shouldn't be exported.

language

bartender is the program that powers many quality of life features.

You can invoke bartender using the binary bart.

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