MODULE ZC @directory

The language currently being generated: "C" or "JS"

For example, to generate code for JavaScript only:

 GENERATE_IF ZC.lang == "JS"
 >>>
   javascript code
 <<<
 }

The permutation currently being generated.

Only when ZC.lang is "JS".

Currently possible values are: "ie6", "ie8", "gecko", "gecko18", "safari" and "opera".

Example:

 GENERATE_IF ZC.permu == "safari"
   safari code
 GENERATE_ELSE
   non-safari code
 }

Return the current position in the code.

This is generated at compile time.

Example:

 THROW NEW("something wrong here", ZC.pos())

Return the code position of the calling method.

When ZC.have("backtrace") is FALSE then NIL is returned.

Example:

 PROC getAtIndex(int idx)
   if idx < 0
     THROW NEW("idx invalid", ZC.callerPos())
   }
 }

Return the stack backtrace, the list of code positions that brought us to the current position.

The position where ZC.backtrace() is invoked is the first position, index zero in the list. The last position is a call from MAIN().

When ZC.have("backtrace") is FALSE then NIL is returned. When used in a method with backtrace=no a compilation error is produced.

Example:

 FOR p IN ZC.backtrace()
   IO.writeLine(p.toString() .. ": " .. p.text)
 }

Return the stack backtrace, just like backtrace(), but skip the first skip entries.

To omit the position this function is called use ZC.backtrace(1).

Return TRUE when feature is supported.

Known features are:

"backtrace" - Wether stack backtrace is available "resolve" - Wether IO.resolve() is available "fork" - Wether fork() is available

Example:

 GENERATE_IF ZC.have("resolve")
   fname = IO.resolve(fname)
 }
