Introduction to Pharen<\/h3>\n

Pharen is a compiler that takes a Lisp<\/a>-like language and turns it into PHP<\/a> code. This combines Lisp\u00e2\u20ac\u2122s advantages of uniform syntax and homoiconicity (among others) and PHP\u00e2\u20ac\u2122s advantage of\u00e2\u20ac\u00a6being everywhere<\/em>. Here\u00e2\u20ac\u2122s some sample Pharen and the equivalent PHP:<\/p>\n

\n
(fn greet-person (name) (. "Hello " name "!"))  (echo (greet-person "visitor"))<\/pre>\n<\/div><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n
\n
\n
\n
\n
\n
\n
<?php function greet_person($name){ return "Hello " . $name . "!"; }  echo greet_person("visitor"); ?><\/pre>\n<\/div><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n
This shows some of the differences between the two languages. Variables don\u00e2\u20ac\u2122t need the $<\/code> prefix, hyphens in names for functions (and variables) are converted to underscores, everything, including string concatenation, looks like a function call, and most things are expressions. The last one means that a function will automatically return the last evaluated expression inside it. More will be explained in later sections.<\/p>\n
Some of the rationale behind Pharen:<\/p>\n
    \n
  1. Abstract out problems and irregularities in PHP\u00e2\u20ac\u2122s own parser and the language itself.<\/li>\n
  2. Compile more sophisticated features, such as closures and macros, to native PHP.<\/li>\n
  3. Insanity.<\/li>\n<\/ol><\/div>\n<\/blockquote>\n

    i can’t believe it. there is something like this. it is just too weird.. heck i might want to try this..<\/p>\n<\/div>\n
