Current Preprocessor Subsitutions:
"compiler.substitute_floats" (currently "substitute_f")
- treat doubles as floats, i.e. 12.3 becomes 12.3f so that people
don't have to add f after their numbers all the time. this is
confusing for beginners.
"compiler.enhanced_casting"
- byte(), char(), int(), float() works for casting. this is basic in
the current implementation, but should be expanded as described
above. color() works similarly to int(), however there is also a
*function* called color(r, g, b) in p5. will this cause trouble?
"compiler.color_datattype"
- 'color' is aliased to 'int' as a datatype to represent ARGB packed
into a single int, commonly used in p5 for pixels[] and other color
operations. this is just a search/replace type thing, and it can be
used interchangeably with int.
"compiler.web_colors" (currently "inline_web_colors")
- color c = #cc0080; should unpack to 0xffcc0080 (the ff at the top is
so that the color is opaque), which is just an int.
Other preprocessor functionality
- detects what 'mode' the program is in: static (no function brackets
at all, just assumes everything is in draw), active (setup plus draw
or loop), and java mode (full java support).
http://proce55ing.net/reference/environment/index.html
- size and background are pulled from draw mode programs and placed
into setup(). this has a problem if size() is based on a variable,
which we try to avoid people doing, but would like to be able to
support it (perhaps by requiring the size() to be final?)
- currently does a godawful scrambling of the comments so that the
substitution doesn't try to run on them. this also causes lots of
bizarro bugs.
Possible?
- would be nice to just type code wherever, mixing a 'static' style
app with a few functions. would be simpler for starting out. but it
seems that the declarations would have to be pulled out, but that
all seems problematic. or maybe it could all be inside a static { }
block. but that wouldn't seem to work either.
b _ bug in comments
sometimes (never when creating a new sketch, only when an old one has been loaded), if I try to add a comment to identify the end of a method class, ie like
void Sample ()
{
<basic code here>
} // end of Sample handler
P5 return me an unexpected 'handler' token error!
And when I change this comment to
} /* end of Sample handler */
everything comes back to normal?!
This don't happen everytimes.. but once it started, the error stay there!
Just try it in your next sketchbook, add some comments at the end of your methods, and see what happen
b _ foreach implementation, via java 1.5
b _ http://jcp.org/aboutJava/communityprocess/jsr/tiger/enhanced-for.html
for (String s : c) {
...
}
// Similarly, the following code could be used
// to calculate the sum of an int array.
int sum = 0;
for (int e : a) // e is short for element; i would be confusing
sum += e;
