Perl 6 Tablets

These are the Perl 6 Tablets, a comprehensive manual, aimed to support many different ways of learning. The content is nicely sorted and indexed and many links allow you to follow your interest freely. For a lightweight introduction, try the Perl 6 Tutorial. If its too easy, read the specs.

DISCLAIMER: This docs moved to tablets.perl6.org/ and no longer represent the current state.
Maybe this will vanish soon!

Perl 6 Tutorial

This tutorial was written for $foo Perl magazine and was published from winter 2007 until autumn 2009, later also in the wiki of the german Perl community. Much editing is being done afterwards to keep the content valid, because Perl 6 is still moving. To understand this tutorial you need basic Perl and general programming skills. Most terms are explained on the way. If you would like to deepen your knowledge, read the Perl 6 Tablets.

Part 1 : Basic Syntax

Part 2 : Operators for Scalars

Part 3 : Operators for Arrays

Part 4 : Hashes and control structures

Part 5 : Captures and Subroutines

Part 6 : Objects and Roles

Part 7 : Text, Rules and Grammars

Part 8 : Introspection and Metaprogramming


What Is This Character Here (WITCH)?

The Perl 6 WITCH is mostly a bunch of hyperlinks that allows one to find documentation for operators, special variables and other features when there is a "mystery character" whose usage is not understood.

Start by clicking on the character you do not understand the usage of. You will be brought to a page that tells how the character is used and/or can point you to compound operators or other uses for the character.

< left pointy
> right pointy
[ left boxy
] right boxy
{ left brace
} right brace
( left paren
) right paren
~ squiggle
+ plus
- dash
@ at
! bang
* star
| pipe
= equal
\ backslash
/ slash
_ underscore
« left french
» right french
^ hat
: colon
, comma
' tick
` backtick
; semicolon
f small f
h small h
o small o
p small p
q small q
x small x
Q big Q

In addition to a handy way to find out what an operator does, it also helps show how Perl 6 tries to allocate characters to uses that have similar or related semantics, by collecting a list of the various uses of a character in one place. Also mentioned are uses of characters from Perl5 and some other languages, so the index can also be used in a "how do I?" fashion.

Want to help build this? Make sure your favorite character, usage, or feature is documented... and that your favorite documentation is linked in. See the WITCH guidelines for some tips.

If any characters are being interpreted as markup where they shouldn't be, enclose them in {{}}.
