/**
* Filters key events for tab expansion/indent/etc.
* <p/>
* For version 0099, some changes have been made to make the indents
* smarter. There are still issues though:
* + indent happens when it picks up a curly brace on the previous line,
* but not if there's a blank line between them.
* + It also doesn't handle single indent situations where a brace
* isn't used (i.e. an if statement or for loop that's a single line).
* It shouldn't actually be using braces.
* Solving these issues, however, would probably best be done by a
* smarter parser/formatter, rather than continuing to hack this class.

* Find & Replace window for the Processing editor.
* <p/>
* One major annoyance in this is that the window is re-created each time
* that "Find" is called. This is because Mac OS X has a strange focus
* issue with windows that are re-shown with setVisible() or show().
* requestFocusInWindow() properly sets the focus to the find field,
* however, just a short moment later, the focus is set to null. Even
* trying to catch this scenario and request it again doesn't seem to work.
* Most likely this is some annoyance buried deep in one of Apple's docs,
* or in the doc for the focus stuff (I tend to think the former because
* Windows doesn't seem to be quite so beligerent). Filed as
* <A HREF="http://dev.processing.org/bugs/show_bug.cgi?id=244"> Bug 244</A>
* should anyone have clues about how to fix.

/**
* Storage class for user preferences and environment settings.
* <P>
* This class no longer uses the Properties class, since
* properties files are iso8859-1, which is highly likely to
* be a problem when trying to save sketch folders and locations.
* <p>
* The GUI portion in here is really ugly, as it uses exact layout. This was
* done in frustration one evening (and pre-Swing), but that's long since past,
* and it should all be moved to a proper swing layout like BoxLayout.
* <p>
* This is very poorly put together, that the preferences panel and the actual
* preferences i/o is part of the same code. But there hasn't yet been a
* compelling reason to bother with the separation aside from concern about
* being lectured by strangers who feel that it doesn't look like what they
* learned in CS class.
* <p>
* Would also be possible to change this to use the Java Preferences API.
* Some useful articles
* <a href="http://www.onjava.com/pub/a/onjava/synd/2001/10/17/j2se.html">here</a> and
* <a href="http://www.particle.kth.se/~lindsey/JavaCourse/Book/Part1/Java/Chapter10/Preferences.html">here</a>.
* However, haven't implemented this yet for lack of time, but more
* importantly, because it would entail writing to the registry (on Windows),
* or an obscure file location (on Mac OS X) and make it far more difficult to
* find the preferences to tweak them by hand (no! stay out of regedit!)
* or to reset the preferences by simply deleting the preferences.txt file.

/**
* Class that orchestrates preprocessing p5 syntax into straight Java.
* <P/>
* <B>Current Preprocessor Subsitutions:</B>
* <UL>
* <LI>any function not specified as being protected or private will
* be made 'public'. this means that <TT>void setup()</TT> becomes
* <TT>public void setup()</TT>. This is important to note when
* coding with core.jar outside of the PDE.
* <LI><TT>compiler.substitute_floats</TT> (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 since it's
* confusing for beginners.
* <LI><TT>compiler.enhanced_casting</TT> 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.
* <LI><TT>compiler.color_datatype</TT> '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.
* <LI><TT>compiler.web_colors</TT> (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.
* </UL>
* <B>Other preprocessor functionality</B>
* <UL>
* <LI>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://processing.org/reference/environment/
* </UL>
* <P/>
* The PDE Preprocessor is based on the Java Grammar that comes with
* ANTLR 2.7.2. Moving it forward to a new version of the grammar
* shouldn't be too difficult.
* <P/>
* Here's some info about the various files in this directory:
* <P/>
* <TT>java.g:</TT> this is the ANTLR grammar for Java 1.3/1.4 from the
* ANTLR distribution. It is in the public domain. The only change to
* this file from the original this file is the uncommenting of the
* clauses required to support assert().
* <P/>
* <TT>java.tree.g:</TT> this describes the Abstract Syntax Tree (AST)
* generated by java.g. It is only here as a reference for coders hacking
* on the preprocessor, it is not built or used at all. Note that pde.g
* overrides some of the java.g rules so that in PDE ASTs, there are a
* few minor differences. Also in the public domain.
* <P/>
* <TT>pde.g:</TT> this is the grammar and lexer for the PDE language
* itself. It subclasses the java.g grammar and lexer. There are a couple
* of overrides to java.g that I hope to convince the ANTLR folks to fold
* back into their grammar, but most of this file is highly specific to
* PDE itself.
* <TT>PdeEmitter.java:</TT> this class traverses the AST generated by
* the PDE Recognizer, and emits it as Java code, doing any necessary
* transformations along the way. It is based on JavaEmitter.java,
* available from antlr.org, written by Andy Tripp <atripp@comcast.net>,
* who has given permission for it to be distributed under the GPL.
* <P/>
* <TT>ExtendedCommonASTWithHiddenTokens.java:</TT> this adds a necessary
* initialize() method, as well as a number of methods to allow for XML
* serialization of the parse tree in a such a way that the hidden tokens
* are visible. Much of the code is taken from the original
* CommonASTWithHiddenTokens class. I hope to convince the ANTLR folks
* to fold these changes back into that class so that this file will be
* unnecessary.
* <P/>
* <TT>TokenStreamCopyingHiddenTokenFilter.java:</TT> this class provides
* TokenStreamHiddenTokenFilters with the concept of tokens which can be
* copied so that they are seen by both the hidden token stream as well
* as the parser itself. This is useful when one wants to use an
* existing parser (like the Java parser included with ANTLR) that throws
* away some tokens to create a parse tree which can be used to spit out
* a copy of the code with only minor modifications. Partially derived
* from ANTLR code. I hope to convince the ANTLR folks to fold this
* functionality back into ANTLR proper as well.
* <P/>
* <TT>whitespace_test.pde:</TT> a torture test to ensure that the
* preprocessor is correctly preserving whitespace, comments, and other
* hidden tokens correctly. See the comments in the code for details about
* how to run the test.
* <P/>
* All other files in this directory are generated at build time by ANTLR
* itself. The ANTLR manual goes into a fair amount of detail about the
* what each type of file is for.
* <P/>

*
* All caret movement is handled by the select() method,

* Note that at this point in time, the new line hasn't

* (in which case it uses the text area's painter cached
* token list). What scrollTo() does next is irrelevant.
*
* After scrollTo() has done it's job, repaint() is
* called, and eventually we end up in paintLine(), whose
* job is to paint the changed line. It, too, calls
* markTokens().
*
* The problem was that if the line started a multiline
* token, the first markTokens() (done in offsetToX())
* would set nextLineRequested (because the line end
* token had changed) but the second would clear it
* (because the line was the same that time) and therefore

OLDSYNTAX PACKAGE README
I am placing the jEdit 2.2.1 syntax highlighting package in the public
domain. This means it can be integrated into commercial programs, etc.
This package requires at least Java 1.1 and Swing 1.1. Syntax
highlighting for the following file types is supported:
- C++, C
- CORBA IDL
- Eiffel
- HTML
- Java
- Java properties
- JavaScript
- MS-DOS INI
- MS-DOS batch files
- Makefile
- PHP
- Perl
- Python
- TeX
- Transact-SQL
- Unix patch/diff
- Unix shell script
- XML
This package is undocumented; read the source (start by taking a look at
JEditTextArea.java) to find out how to use it; it's really simple. Feel
free to e-mail questions, queries, etc. to me, but keep in mind that
this code is very old and I no longer maintain it. So if you find a bug,
don't bother me about it; fix it yourself.

* Format for Discourse Tool
* <p/>
* Original code by <A HREF="http://usuarios.iponet.es/imoreta">owd</A>.
* Revised and updated for revision 0108 by Ben Fry (10 March 2006).
* This code may later be moved to its own 'Tool' plugin, but is included
* with release 0108+ while features for the "Tools" menu are in testing.
* <p/>
* Updated for 0122 to simply copy the code directly to the clipboard,
* rather than opening a new window.
* <p/>
* Updated for 0144 to only format the selected lines.
* <p/>
* Notes from the original source:
* Discourse.java This is a dirty-mix source.
* NOTE that: No macs and no keyboard. Unreliable source.
* Only format processing code using fontMetrics.
* It works under my windows XP + PentiumIV + Processing 0091.
