1. The best web language.
language
Which is the best programming language for you?
Perl?
PHP?
OR
Python? Ruby?
ASP?
2. The one true answer is:
LOL Code!!1one
LOLCode is an esoteric language by geeks with too much free time.
There are multiple lolcode interperters, parsers, and even compilers.
“Laser Cats”
3. I wrote the first working lolcode parser
And the first lolcode powered website.
I am one of those geeks.
“LOLCode By O'RLY”
4. Basic Usage
CODE SNIPPET
!BEWARE!
HAI <- Opening tag
MUST HAS STDIO <- Require File
VISIBLE quot;HAI WORLD!quot; <- Print
KTHXBYE <- Closing Tag
5. Variables
CODE SNIPPET
!BEWARE!
I HAS COLOR1 <- Initiate Variable
I HAS COLOR2 IZ GREEN
^- Initiate and Set Var
COLOR1 IZ RED
^Set existing var
6. More Variables
CODE SNIPPET
!BEWARE!
VISIBLE “COLOR IS &COLOR1&”
^- Print with Var replacement.
IVAR IZ 1 < Set var to 1.
IVAR UPUP!< Increment twice.
IVAR UPUP!
< IVAR is 3.
BTW THIS IS A COMMENT
^- Use BTW to comment line.
7. Control Structures
CODE SNIPPET
!BEWARE!
IZ &IVAR& == 1 < IF.
BTW IF
VISIBLE quot;YEAH RLYquot;
VISIBLE __SKY__ <-Print Constant
NOWAI
BTW ELSE <- ELSE
VISIBLE quot;NOWAIquot;
KTHX
9. Arrays
CODE SNIPPET
!BEWARE!
ARRAY IZ BUCKET
< Create Bucket
^Variable Name
0 FISH quot;zeroquot; !! < Numerical
1 FISH quot;onequot; !! < Keys
< String Keys
two FISH quot;twoquot; !!
BUCKET
<- Prints “two”
VISIBLE &ARRAY#two&
10. Multidemensional Arrays
CODE SNIPPET
!BEWARE!
ARRAY IZ BUCKET
< Create Bucket
^Variable Name
0 FISH quot;zeroquot; !!
three FISH IZ BAG <- Use bag or buckets
!! FISH quot;threequot; !!
!! FISH quot;twoquot; !!
^New Dimension
BAG
BUCKET
<- Prints “two”
VISIBLE &ARRAY#two,1&
11. BAG Arrays
CODE SNIPPET
!BEWARE!
ARRAY IZ BUCKET
< Create Bucket
^Variable Name
0 FISH quot;zeroquot; !!
three FISH IZ BAG <Create BAG
!! FISH quot;threequot; !!
!! FISH quot;twoquot; !!
BAG ^BAG uses auto
incremented keys.
BUCKET
<- Prints “two”
VISIBLE &ARRAY#two,1&
12. Looping
CODE SNIPPET
ARRAY IZ BUCKET !BEWARE!
< Create Bucket
0 FISH quot;zeroquot; !!
1 FISH quot;1quot; !!
2 FISH quot;2quot; !!
BUCKET
<- Foreach
IM IN UR ARRAY ITZA NUMBA
VISIBLE quot;&NUMBA&!quot;
^Prints “zero!1!2!”
KTHX
13. Functions
CODE SNIPPET
!BEWARE!
SO IM LIKE UPPING WITH VAR VAR2=0
^Var Name ^Arguments ^Default
Value
VAR UPUP!
<- Increment VAR
I FOUND MAH VAR<- Return VAR
KTHX <End Function
VISIBLE quot;FOUR UP? ITZA quot;.UPPING(4)
^Prints “5”
14. Advanced Features
CODE SNIPPET
!BEWARE!
THEVAR IZ GOLD
VARNAME IZ THEVAR
VISIBLE &&VARNAME&& <-Prints “GOLD”
^- Variable Variable
ALWAYZ SKY IZ BLUE <- Set Constant
VISIBLE __SKY__ <- Print Constant
15. Embed in HTML
CODE SNIPPET
<html> !BEWARE!
<head>
<title>LOL Power</title>
<- HTML
</head>
<body> Subset of XML
HAI
MUST HAS STDIO
VISIBLE quot;<!-- Copyright 2007 Jeff
Jones, www.tetraboy.com -->nquot;
VISIBLE quot;HAI WORLD!quot;
KTHXBYE
^ Code in tags is parsed.
</body>
</html>
16. SQLite Databases
CODE SNIPPET
!BEWARE!
CAN HAS SQL? <- Include SQL Lib
DBASE IZ GETDB('lolz')<-Select DB File
FUNNAHS IZ DBUCKET(
^Get Array from DB
&DBASE&,
quot;CAN I PLZ GET joke ALL UP IN funnahsquot;
)
^LOL-SQL.
“Select joke from funnahs”
17. SQLite Databases, Part Deux
CODE SNIPPET
!BEWARE!
CAN HAS SQL? <- Get Array from DB
DBASE IZ GETDB('lolz')
FUNNAHS IZ DBUCKET(&DBASE&,quot;CAN I PLZ
GET joke ALL UP IN funnahsquot;)
< Loop It
IM IN UR FUNNAHS ITZA JOKE
VISIBLE quot;<P>quot;.&JOKE#joke&.quot;</P>quot;
^Print each joke
KTHX
(dbucket returns assoc array)
18. Tetra LOLCode Parser
How to make a new lang work?
With little to no work?
Convert it to PHP!
How?
preg_replace!
function lol_core_parse($code)
Takes incoming code and runs through 36 regular expressions
/e is your new best friend.
19. Tetra LOLCode
Works with apache!
Easiest way to run .lol on apache?
Set .lol to parse as PHP
Use PHP's prepend/append
Output Buffering to catch LOL
Parse src
Write source to temporary file
Include temporary file
