What's new in Processing 3.5.4

Jan 20, 2020

Changes:
Don't remove entries from Recent menu on Save As
Use ctrl-page up/down for changing tabs on Windows
Show error when .properties file is missing from a Library/Mode/Tool.
Fixes:
Tweak Mode working again (fix from Gal Sasson)
Fix potential highlighting issue that wasn't selecting portions of text
Names in the contribution listing are no longer case sensitive (It was placing lowercase names at the bottom of the list.)
Clean up a lot of bad temp file handling in the contrib manager
Fix NullPointerException in installPreviouslyFailed() on startup
Internal:
Ignore subfolders in the "libraries" directory. This was causing some nasty startup issues for folks, and other hard-to-track bugs. Hopefully there aren't any installs that relied on this behavior.
Update AppBundler to use newer SDK, recompile:
Edit build.xml files and appbundler to preserve more attributes

New in Processing 3.5.3 (Jan 16, 2020)

New in Processing 3.4 (Jul 27, 2018)

Show alternate error message on Windows when jnidispatch.dll or core.jar have been removed by Windows Defender or Microsoft Security Essentials. This has been a huge headache for us. We've repeatedly submitted the software and asked Microsoft for help, but haven't had any luck. If you run into this issue and would like to help, please submit the files to Microsoft here: https://www.microsoft.com/en-us/wdsi/filesubmission Perhaps if there are enough reports, they'll understand this is affecting a lot of people.
Contributed libraries/examples/etc that redirect to https URLs now working.
It's now possible to make your own theme file for Processing. Copy the theme.txt file from inside the Processing folder to your sketchbook folder, and then edit away. For instance, to make a dark theme:
It's now possible to copy the text of the status bar. Click the clipboard icon at the right-hand side to copy the text to the clipboard. To search immediately, use shift-click. The default search engine is Google, but you can modify that by altering the 'search.format' line in preferences.txt
Added pyde as a supported extension, so double-clicking on Python sketches will launch the PDE.
Added Double and Long versions of the data classes. Not sure if we'll keep these, but we're trying them out.
Also add subset(long) and subset(double) to PApplet
Changed the internal Sort class to use int for comparisons for better accuracy, especially when working with double and long values.
Consistently implemented write(PrintWriter) in the List and Dict classes
Added save(File) to the List and Dict classes
Prevent Table.sort() from throwing NullPointerException with empty cells
Fixed up the Welcome dialog. When closing the window or hitting ESC, the "show this" selection is recorded. Also clicking that text will toggle the checkbox on/off, as users would expect.
Redesigned the Rename window to be less ugly. Now closes when ESC is pressed, and the default action is set so hitting Enter will work properly.
Rewrite exec() to do threads, also handle fast/excessive output cases
Rewrite requestImage() to fix errors/slowness/concurrency problems
Refactoring inside the completion code
Now using Java 8u181. https://github.com/processing/processing/pull/5586
Change lack of blendMode() to a warning rather than an error in PDF
Updated the copyright and year in the launch and About screen.
A large number of changes and fixes for ARM submitted by Gottfried, who also posted 3.3.7.1 and 3.3.7.2 interim releases with some of these changes already present. Now we're back on track with 3.4.

[ new additions ]:
You'll be greeted by a Welcome screen. We haven't finished the text for one of these yet, so you'll see some lorem ipsum (fake) text instead. We'll wrap that up before the beta release. https://github.com/processing/processing/issues/3358
[ breaking all of the things ]:
For Tool and Mode authors, you'll need to make some (small) changes. These aren't structural, but will require a rebuild of your code. Our hope is that this will be the last round of changes for the 3.x series, and that it's now safe to update your Modes and Tools to be compatible with the final 3.x release. Changes in this release: - Several classes have been moved to a new processing.app.ui package. The processing.app package was much too unwieldy and made it difficult for people to hack on the PDE code. - Several functions have moved out of Base and into Util (or Toolkit). Most of these are file-related (removeDir() and others), but the Base class had simply grown to a ridiculous size. It remains enormous but is a little less ridiculous.
Removed the init() method from PApplet; it's no longer needed

BREAKING THINGS FOR THE FUTURE:
Added fullScreen() method to make it far easier to run sketches using the full screen.
smooth() and noSmooth() can only be used once per sketch, in setup().
Re-opened the Gates of Hell by adding chaining operations to PVector
Changed exec() and open() to use varargs. Changed open() to launch() to prevent problems with Python Mode.
Replaced --full-screen command line option with --present to untangle full screen versus the "Present" command that places blanks the rest of the screen around a sketch.
ortho() function is being reworked to make it compliant
OTHER CHANGES AND ADDITIONS:
Added new application and export icons. Mmm!
Add retina/high-res display support to OpenGL
Add pixelDensity(2) command to enable retina or high-dpi mode for your sketch. Make things look beautiful and crisp on expensive hardware!
Added displayDensity() methods to get the pixel density for individual displays. displayDensity() returns the density (1 or 2) of the default (or currently selected) display, displayDensity(1) returns the density of display 1. Guess how you get the density of display 2?
Add useful constructors to the Int/Float/StringList classes
BUG FIXES:
Fix monitor numbering problems
Full screen doesn't work on second window w/o present mode
Full screen on OS X 10.9 has incorrect placement
"Run sketches on display" not working properly
Comments influencing code (preproc issues in parsing)

GROUP shapes are broken in 3.0a9
Only a quarter of the sketch is appearing in 2x mode

Fixes:
size() sometimes erratic (i.e default size used) This was often seen with large setup() functions, or on more esoteric platforms. https://github.com/processing/processing/issues/1672
Command line "processing-java" was broken https://github.com/processing/processing/issues/3224
Sketchbook window requires restart of Processing before updating after sketchbook location change. https://github.com/processing/processing/issues/3214
Replace & Find was reading "Find & Replace" https://github.com/processing/processing/issues/3247
"One file added to sketch" message when two files added
pop() was not implemented correctly in String/Int/FloatList
Errors in file name case differences not correctly reported https://github.com/processing/processing/issues/3235
Single Frame (no screen display) PDF broken https://github.com/processing/processing/issues/3280
"Buffers have not been created" error for sketches w/o draw() https://github.com/processing/processing/issues/2469
Changes:
Behind the scenes, the size() method is now moved out of setup() and into a method named settings(). The settings() is called before setup() and is the only place where size() can be used. If using
Processing without the PDE (i.e. with another IDE like Eclipse), remove the size() method from setup() and instead place it like so:
public void settings() {
size(400, 400, P3D); // your size() command here
The rest of your code remains unchanged. The PDE does this transparently, so 99% of people won't even notice this change. However, it allows us to fix (and avoid) a lot of really nasty complications that come from how Processing lets you switch between 2D drawing and OpenGL and even something like PDF with simple changes to the size() method.
We're trying "settings()" as the method name, but that may change in a future alpha release. Once we hit beta, it will not change.
For those familiar with them, the sketchWidth(), sketchHeight(), sketchRenderer(), etc methods should no longer be used. This new implementation of the settings() method is a simpler solution.
Added SVG Export library (works like PDF Export). This has not been tested heavily yet.
Replace Tweak Mode ColorSelector with JComponent version https://github.com/processing/processing/issues/3209
Fairly major rewrite of createShape(), shouldn't affect anything, but keep an eye out for regressions.
Add new String/Int/FloatDict constructors that take an array for useful static/ initialization
Move svgz handling to PApplet, remove objz handling
Implement blendMode in FX2D https://github.com/processing/processing/issues/3275
Added StringList(Object...) constructor to handle a grab bag of objects
Added appendUnique() to Int/Float/StringList to only add unique items to a list. Replaces the following code, making "set" operations easier: if (!theList.hasValue(value)) {thiList.append(value);}
Inside main(), don't set 'args' to a zero-length array if no args were passed in, instead leave 'args' null.

Debugger "String is null" error when hitting breakpoint https://github.com/processing/processing/issues/3265

New in Processing 3.0 Alpha 2 (Aug 1, 2014)

Changes:
Added a new sketchbook location, so that you can have separate sketchbooks with 2.0 and 3.0 releases. The downside is that they won't stay in sync, but the upside is that sketches that haven't been updated, or conflicting Libraries, Modes, or Tools won't cause trouble with the other version. The new preference is called sketchbook.location.three (the old preference was sketchbook.location). If you already have a 2.0 sketchbook, that will be used by default with 3.0 until you change it in the Preferences window.
Neglected to mention with the previous release that the video library has been removed from the default download. This decreases the size of the Processing download by about 20%. In addition, it was only the video library for the platform being downloaded, and with the return of cross- platform application export, that could cause sadness. To use the video library, use the "Add Library..." menu and select it from the list.
Added a new preference for the 3.0 sketchbook location, so that a separate sketchbook (and with it, different Modes, Tools, and Libraries) can be used with Processing 3.0 versus older versions of 2.x.
Remove default menu bar hack for OS X
Move to native OS X full screen (supported in 10.7 and later) https://github.com/processing/processing/issues/2641 This allows us to remove native code for hiding the menu bar. But it may introduce more quirks, we'll have to test it out.
Fixes:
The Examples weren't included in 3.0a1.
Fix "No such file or directory" error when exporting on Mac OS X. This bug actually meant that OS X apps weren't signed
Prevent opening sketches multiple times
Disable Mac OS X export button on other platforms
Removed duplicate 'fonts' folder in the download
Removed welcome message from the sound library
Get the 'modified' indicator working on OS X document windows again
Do bounds check on setVertex(PVector)
Using createGraphics() w/o begin/endDraw(), don't attempt drawing w/ image()
The data classes:
Add copy() method to Table
Return null from getString() with float and double values that are NaN. Fixes how saveTable() works (writes blank entries instead of NaN).
get(5) with an empty Int/Float/StringList was returning 0
FloatDict and FloatList should always put NaN values at the end on sort.

BUG FIXES AND ADDITIONS:
Sketches only starting once, or half-starting and hanging on Mac OS X. A major problem on OS X, thanks to David Fokkema for tracking down a fix.
Re-open current sketch in new mode editor if file extension is compatible. This was a regression in 2.1.2 due to the Python Mode changes.
Crash in the 'recent' menu on startup
Avoid conflict when some goofball has installed JNA DLLs in your path.
Add support for "import static" syntax from Java
Improve error handling during Tool loading. In previous releases, an out of date QuickReference Tool was able to hang Processing. No longer.
Save the previous open dialog so that we return to the directory
"if-else" block formatting wasn't following Processing conventions
Tab characters not recognized or handled in the editor (since 2.1)
Chinese text is overlapped in Processing 2.1 editor
EXPORT TO APPLICATION:
The return of multi-platform export! Create applications for Windows and Linux while using OS X. Create a Linux application from Windows. Against my better judgement, we're supporting it again. It's extremely difficult, but was disappointing to remove it earlier.
When exporting with local Java embedded, always use that version
Change Windows export to use launch4j instead of our custom launcher. This will fix many, many problems, but may introduce some new ones.
Windows (64-bit) now creates a proper .exe instead of a .bat file
Exported apps on Windows 64 were not quite working correctly
Improved icons on Windows for exported apps
Add additional language and explanation to the Export dialog box
Make it possible to edit the background colors for full screen as well as the stop button color directly from the Export dialog box
Exported apps reporting as "damaged" on OS X. You'll have to install Xcode to remove the warnings, but it's possible

Added an option to not embed the Java runtime into an exported application. This saves you the 100 MB footprint, but requires your users to install Java 7u45 or later. Details on the same page that nobody read last time: http://wiki.processing.org/w/Export_Info_and_Tips
The new println() (see the beta 1 notes) makes some old code behave a little differently. In the past, println() with an array would write out the array, one element per line, with the index in the front.
i.e.: PFont.list()) would write something like this to the console:
[0] "Serif"
[1] "SansSerif"
[2] "Monospaced"
[3] "Dialog"
[4] "DialogInput"
[5] "ACaslonPro-Bold"
[6] "ACaslonPro-BoldItalic"
Now it's going to write out something like:
Serif SansSerif Monospaced Dialog DialogInput ACaslonPro-Bold.
To get the old behavior, use printArray(). It's the price of progress, and shouldn't really "break" anyone's code since it's just writing to the console. We think the new syntax outweighs the downside of the change.
With arrays of primitive types (int[], float[], anything that's not an object), we've added code so that println() works as before. But we can't do the same for arrays of objects, such as String.
The preference for font smoothing (anti-aliasing) in the editor has been reset in this release. Fonts are unusably gross on OS X (and Linux) without smoothing and Oracle's version of Java (now in use with 2.1), and many longtime users have anti-aliasing turned off. You can still turn off smoothing in the Preferences window, but the results may be poor.

Updated to another version of JOGL (jogl-2.1-b1115, gluegen-2.1-b735) for OS X 10.9 support.

New in Processing 2.1 Beta 1 (Oct 21, 2013)

For people using Eclipse, the new print() and println() methods add some quirks because of how println() works for arrays in previous versions of Processing. When printing an array, you should instead use the new printArray() function, which works the same as the old println().
This will help avoid the compiler warnings with Eclipse and others.
In the PDE, this should be transparent, because warnings are not shown.
Update the JavaDoc, remove java.* package prefix ugliness. Also link out to the online version of the Oracle documentation.
Major work on the source and the build scripts as we completed the transition to Java 7, and away from Apple's deprecated Java 6.
Incorporated a version of Oracle's appbundler for OS X build. Made heavy modifications to the original version to add features and simplify.
Culled un-needed resources from the Java 7 runtime to save space.
Unfortunately Java 7 is also much larger than Java 6, so the size change isn't as considerable as we would hope.
Remove unused/outdated 'Mangler' Tool example
Remove video library for other platforms in download. This saves significant space because we're not doing cross-platform export anymore.
Update apple.jar file with new version
Update build instructions on Github
Many changes to the Supported Platforms page
Updates to the Export page to cover changes in this release
Removed the 32- and 64-bit selector from the Preferences on OS X.
Java 7 on OS X only supports 64-bit, so 32-bit is no longer available.
editor fixes:
Deal with null/missing folders for Tools and Modes
Non-compliant libraries cause crash on "Add Library"
Bad tools could bring down the environment

Notify users that Modes and Tools require restart.
Change the location of the manager download to something more stable.
Restrict library categories to the ones in the document. If it's not correct, shows up as 'other'.
Catch Errors (not just Exceptions) when loading libraries, modes, and tools. Handles UnsupportedClassVersionError and other quirks.
Redo handling of "old" versions of contributions.
Update example list when library is installed
Data, data, data:
Error in IntList and FloatList insert()
Add a sort() method to Table.
Implement version of Table that takes a dictionary file. Syntax is: Table t = loadTable("bigdata.tsv", "dictionary=bigdata-dict.tsv") This allows you to set the data type of columns before loading, which provides much better performance and lower memory usage.
Constructing table from an Iterator is missing
Add sum() to IntList and FloatList
When using increment() on IntList, make sure the index exists and automatically resize the list if necessary. This is more in keeping with increment() in the Dict classes.
getSubset() broken in IntList, StringList, and missing from FloatList
Add join() method to Int/Float/StringList
Add getContent(defaultValue) to XML
Add isNull() (returns boolean) to JSONObject/Array
Add getXxxx(xxx, defaultValue) methods to JSONObject/Array
Internal changes you'll never notice... unless I broke something:
Add an exception wrapper for startup, hopefully we can catch/debug more "Processing can't start!" issues with this.
Update JNA from 3.2.4 to 3.5.2.
Updated JOGL to 2.0.2.
Added methods to move files to Trash/Recycle Bin where available.
Implement basic proxy server support for update checking and the contribution managers.
Basic getShape(ch) implementation for font glyph shapes. Not finished and (therefore) not yet documented.
Change QUAD_BEZIER_VERTEX to QUADRATIC_VERTEX to match the API call (because this lives inside PConstants).
Add retina switch for PApplet to set useActive with OS X and 7u40. Prevents speed/performance issues with old sketches on retina macs.
Add error message for raspberry pi (and others?) about int buffers
Changes:
Experimental Mode has been removed from the default download, so that it can be updated more frequently. Install it and help us test what will become the 3.0 release of Processing!

changes:
Removed all imports that aren't covered in the Processing reference. If you use java.awt, java.util, or other classes in your sketch, you will need to add an import line to the beginning of your sketch.
Only the classes that are covered in the reference (HashMap, ArrayList, and some others) are now imported by default. This has been done to improve overall cross-platform parity and to avoid users unknowingly adding Java classes, and then the sadness that comes when switching to Android or JavaScript modes.
The list of imports is now hard-coded (no longer read from preferences.txt) and includes the following: import java.util.HashMap; import java.util.ArrayList; import java.io.BufferedReader; import java.io.PrintWriter; import java.io.InputStream; import java.io.OutputStream; import java.io.IOException;
If we're missing anything that's not covered in the reference, please let us know via the bugs database.
A new "experimental" mode has been added. It's the start of combining two of our Google Summer of Code projects (DebugMode and XQMode) to enable a debugger and on-the-fly error checking. We're including it in the release so that folks can test it out and let us know how it's doing. The interface still needs work and its innards may be a bit buggy, but it represents some exciting upcoming improvements for the PDE.
hint(ENABLE_ACCURATE_2D) has been renamed to hint(DISABLE_OPTIMIZED_STROKE) to better reflect what it actually does. Reference has been added. OpenGL drawing is significantly faster when the fill and stroke of a shape is drawn separately. This leads to visual artifacts on shapes where both fill and stroke is enabled (not a great idea in 3D anyway), so this option fixes the visual artifacts at the expense of speed. http://code.google.com/p/processing/issues/detail?id=1302
Sketch names can no longer begin with underscores (fixes an Android compatibility issue). This was changed in recent releases, but missing here. http://code.google.com/p/processing/issues/detail?id=859
More Mac OS X key bindings have been implemented in the editor: http://code.google.com/p/processing/issues/detail?id=1354 http://guides.macrumors.com/Keyboard_shortcuts§ion=10#Text_Shortcuts
Set quality level higher when exporting JPEG images. This will result in larger JPEG files with save() and saveFrame(), but the default quality setting in the past was unacceptable for many/most projects. http://code.google.com/p/processing/issues/detail?id=58 See the bug report link for how to implement in case you want to set the quality lower (or even higher) than the new default.
Table row iterating syntax has changed. This code: for (TableRow row : table) { ... } has now changed to for (TableRow row : table.getRows()) { ... } (This may change to rows() on the next round, pending other API tweaks)
Change default for shift-backspace to just be backspace. To change it back, set editor.keys.shift_backspace_is_delete=true in preferences.txt.
Implement clip() and noClip() to set the clipping region.
Added blendMode() feature. http://code.google.com/p/processing/issues/detail?id=1385

Disable Quartz renderer to fix line blending problem on OS X. This older renderer was faster but had some bugs, like one that caused lines to composite incorrectly when alpha was used. Add "PApplet.useQuartz = true;" into your PApplet.main() function to switch back to the old method: http://processing.googlecode.com/svn/trunk/processing/build/javadoc/core/processing/core/PApplet.html#useQuartz

Libraries - All libraries must be placed in a folder named "libraries", inside the sketchbook folder. Do not use the main "libraries" directory in the Processing distribution, as it is reserved for the core libraries, and is not visible on Mac OS X.
XML - The XML library is now included by default, so you won't find it in the Import Library menu anymore. In addition, the XML library since 0135 has been greatly improved, making it compatible with far more documents.
Processing.app - The Mac OS X release of Processing is now a single .app file, more befitting an OS X application.
Processing.exe - The Windows release has a new launcher based on launch4j. Unfortunately, some machines have a problem with the new launcher that we haven't been able to track down. If you have trouble, please help us find the problem. PDE files are also now double-clickable on Windows.
OpenGL - All OpenGL sketches now use 2x full screen anti-aliasing. This means that these sketches are always smooth, and the smooth() and noSmooth() commands are ignored. To return to the behavior found in the beta releases, see the hint() reference.
P2D and P3D - The P2D renderer has returned (see the size() reference) and smoothing is now enabled for both P2D and P3D. Smoothing support is unfortunately incomplete, however, and sometimes thin lines can be seen inside shapes. This is a very high priority bug to be fixed in a future release.
Candy and PShape - The Candy SVG library has been merged into the core, which brings along a new loadShape() command and a new PShape object. The special powers of PShape will be rolled out in future releases. For the time being, loadShape() works best with the default renderer (JAVA2D). Complex shapes will often appear jagged or not at all when rendered with P2D, P3D, and OPENGL. We've also added better support for SVG files created with Inkscape.
PVector - We've added a new class called PVector, which is a simple three-dimensional vector (also known as point or tuple) class. This is useful for storing point data, or operations on 3D points.
Tools - A new Tools API has been created for developers who want to contribute code that extends the Processing Development Environment in some fashion. Let your creativity flow with fantastical contributions like "Color Selector 2.0", "ROT13 Code Mangler", and "I Am Rich". Visit the developer page on tools for more information. Similar to libraries, tools are installed in a folder of the same name within your sketchbook folder.
Asynchronous Images - Big JPEGs and small pipes? We've added a new requestImage() method that loads an image in the background so that your sketch doesn't freeze when loading lots of large images over a slow connection.
Sound - We've added Damien Di Fede's Minim library to the download. It uses the JavaSound API to provide an easy-to-use audio library. Minim has a simple API while still providing a reasonable amount of flexibility for more advanced users. Many thanks for Damien for his hard work on this excellent library.
Present - Present mode (full screen) is handled differentl in 1.0. When run inside the PDE, only Mac OS X uses full “screen exclusive mode” with Present. Windows and Linux just do full screen windows. When run outside the PDE, all three simply create an undecorated window the size of the entire screen, and on the Mac, an option is added to the Info.plist file to hide the dock and menubar (since that cannot be done programatically from inside Java applications).
Compiler - We've removed the old Jikes compiler and are now using the ECJ compiler from the Eclipse project. We've also tried hard to improve the quality of error messages, though some are still real gems that sound like error messages from mainframe computers in 1970s films. If you don't like the messages please help us improve them.
Internationalization - For better internationalization support, we've changed to UTF-8 encoding when loading and saving sketches. Sketches that contain non-ASCII characters and were saved with Processing 0140 and earlier may look strange when opened. Garbled text and odd characters may appear where umlauts, cedillas, and Japanese formerly lived. If this happens, use the "Fix Encoding & Reload" option under the Tools menu. This will reload your sketch using the same method as previous versions of Processing, at which point you can re-save it which will write a proper UTF-8 version.
Java - Linux and Windows now inlude Java 6 update 10 with the download. We still don't have support for Java 1.5 syntax yet, but we hope that the performance boosts in Java 6 will help applications run well.

The most significant change in this release is the introduction
of a new runner system. This means that we'll be able to make the stop button behave properly, shut down sketches correctly, have better error handling, and eventually add debugger support. On the downside, sketches may start a little more slowly, and it may be a bumpy transition as we get things working (strange errors when you hit Run).
We are moving to Java 1.5 as a minimum requirement for running Processing, as well as sketches created with it. This is an attempt at self-preservation as we try to limit the number of platforms that we support. Note, however that we *still do not*
support Java 1.5 language extensions (enum, enhanced for loop,
generics, etc.) If you find places in the code or reference that refer to Java 1.4 support, please let us know via dev.processing.org/bugs.
We've switched to NanoXML instead of NanoXML-Lite. This means that the export size of the XML library has changed from ~6k to ~30k. The new version is much better at handling a broader range of XML
content. The API should be the same and your code should work without changes (unless you're playing with namespaces, in which case those have to be specified differently).
Major bug fixing happened in handling the class path issues and dealing with how libraries are loaded. With any luck, this should
fix the dreaded aiexport bug. It should also give better results
when multiple libraries are installed on the system. However, it may mean that some libraries (or jarfiles) that shouldn't have been working before will now (properly) no longer work.
curveTangent() implemented by Dave Bollinger. (Thank you!)
Added support for quadratic (as opposed to just cubic) curves to the Candy SVG library.
Altered Processing.app on Mac OS X to use the Quartz rendering engine. In OS X 10.5, Apple switched renderers, which made most
Processing sketches run considerably slower. Thanks Apple!
Added ctrl-/ to comment a block of code
Minor change to default window dimensions to support the Eee PC
Updated reference and slight reorganization to fix a handful of
broken links. Moved the FAQ to the Processing site (no longer
included in the download.)
