cJass is small, but useful preprocessor for JASS2 interpreted language, used in Warcraft III by Blizzard ent. Its main purposes are to make the process of writing the script simple and comfortable and to increase its readability.

Here is what cJass code looks like:

include "cj_types.j"

bool bIsFlag = true

timer MyGlobalTimer = new timer

void SomeFunc (int i) {
  if (i>MAX_VAL) { i = MAX_VAL }

  bool b = !bIsFlag
  float a = 2.
  int c = -2
  a *= c + 8.

  do {
  } whilenot (a < c++)

The program is designed for use with Jass New Gen Pack, is compatible with vJass (0.A.2.B) parser and is run before it.

Project Horus: 0.4.6.T (22.09.2009)

The aim of project Horus is to commit a full rewrite of Scintilla lexer library, which is used by TESH for highlighting JASS syntax. The resulting library works better than the original one, folds and highlights cJass syntax, folds vJass better than the original one and also highlights delimited comments.
To use it, simply unzip the archive to your NewGen folder or use cJass stable installer.
