This wiki is all about APL, an array-oriented programming language that will change the way you think about problems and data. With a powerful, concise syntax, APL lets you develop shorter programs that enable you to think more about the problem you're trying to solve rather than how to express it to a computer.

Running APL

Main article: Running APL

Traditionally a commercial language, there are now quite a few APL dialects available to download for free without feature limitations, and most of these can be tried online without installing anything.

Who are you?

I am new to programming

I am a programmer but new to APL

I want to learn intermediate APL

I'm an old APLer who wants to learn modern APL

Who uses APL?

There are many case studies of both hobby and real-world APL applications.

There is a popular APL chat room on Stack Exchange.

There are active user groups all around the globe, many of these hold regular in-person meet-ups.

Examples

APL's terseness lends to substantial programs begin expressable in a small space, relative to many other programming languages. Here are some examples:

Split text by delimiter	','(≠⊆⊢)'comma,delimited,text'
Conway's "Game of Life"	`{↑1 ⍵∨.∧3 4=+/,¯1 0 1∘.⊖¯1 0 1∘.⌽⊂⍵}`
