DEV ENVIRONMENT:
x p5-svn build automation
x template mode
	x provide more methods to override
x create repo



FLORIAN TODO:
x get Processing SVN version and compile and run that
x get to know the internal process of running a sketch (collect code and libraries, precompile, compile, run, ..)
x set up a repo for us
x set up a contributed mode skeleton and make that compile against and show up in the SVN version as mode
x replace runner with the debugger runner
x add interface elements to the editor window as needed (line numbers, setting breakpoints, ...)
x sketch and add additional interfaces (windows) as needed

Icons
x Bilder wären besser als die Abkürzungen
x nachdem "run" und "debug" ja nun getrennt sind, sollten die in einen eigenen Block, änhlich wie "new"/"open"/...
  (R)(S)  (DBG)(CNT)(ST)(STI)(STO)  (N)(O)(Sv)(Ex)
– (VAR) Knopf braucht man nicht, da man den Inspektor einfach immer zeigen sollte wenn man die Session startet
– "Set Breakpoint" Knopf würde ich über einen Kurzbefehl machen wie Kommentieren (cmd-B ?)
x "BRK" ist ge-highlighted beim Sichern
– Sollten die nicht benutzbaren Icons deaktiviert sein wenn man im DebugMode ist?
x DBG sollte gehighlighted sein wenn man in der Session ist
– (CNT)(ST)(STI)(STO) sollten erst aktiv werden wenn man an einem Breakpoint hängt

Variable Inspector
x Order- und File-Icons? Icon nach Datentyp? Primitive jeweils und generisch für Objekte?
x Kann man die internen und default Vars verstecken?
x "this" -> Sketch-Name
x "Locals" -> "Locals at breakpoint #4"? ... "at line #123"?

Editor
x Kann man prüfen und warnen daß man erst saven muß? ... sonst ist nicht klar warum manchmal die Breakpoints nicht gehen
x das rosa Highlight sieht sehr nach Fehler aus ... könnte das nicht eine andere Farbe sein? .. grün / blau?

Mode
x Mit einem Breakpoint in draw() scheint println() nicht zu gehen?
x Mit einem Breakpoint in draw() updated sich die Zeichenfläche nicht ... man sieht also gar nicht was passiert
x Braucht man die Ausgabe des fokusierten Codes in der Konsole wirklich? .. und die VM events sind nur für dich zum Debuggen, oder?
x Die default Breakpoints bei setup() / draw() braucht man nun nicht mehr? ... oder?

2012-06-29
x 1)
Wenn man steppt (step in) und die Zeile ist in einem anderen Tab, dann stimmt zwar das Highlight, aber der Textview scrollt nicht an die Stelle ... ist das unser oder Ben's Problem?

x 2)
Wir sollten unbedingt Tutorials einplanen gegen Ende des Projekts

x 3)
Ich finde "Call stack" und die Variablen sollten sich nicht so mischen, können wir das Fenster nur "Inspector" nennen und "Call stack" und "Variables" splitten? .. in zwei Felder?

x 4)
Die Var Liste ist sehr unübersichtlich ..
xxxxx (java.lang.String): "blah blah"
könnte sein:
(String icon) xxxxx: "blah blah"

x 5)
... selbe Stelle:
XXXXX (blub$Klasse): instance of blub$Klasse
... den "instance of" Kram braucht man nur wenn es nicht die selbe Klasse ist wie der Var-Typus

x 6)
Wenn keine Locals da sind, sollte das Icon trotzdem ein Folder sein ...

x 7)
"Leere" Objekt-Variablen haben im Inspektor ein "Öffner-Dreieck" ... wenn man das klickt verschwindet es einfach nur. Klar, du lädst den Inhalt nach dem Klick, aber es ist für den User unbefriedigend wenn man die Dinger dauernd klickt und dann nichts passiert. ... können wir anzeigen ob die leer sind, oder zumindest das Dreieckchen behalten?

x 8)
Variablen sind sortiert? ... ginge das alphabetisch?

x 9)
Könnten wir Name / Wert als Kolumnen anlegen damit es leichter zu lesen ist?

10)
könnte man einen Knopf bei DBG machen, der es erlaubt für eine Weile laufen zu lassen ohne zu breaken? .. manchmal dauert es ja eine Weile bis sich die Dinge im Sketch entwickeln.


2012-07-14
x 1) UX
Wenn man im DBGM ist (läuft) und einen Breakpoint toggln will passiert nichts. Klar daß das einfach nicht geht, könnte aber entweder der Button inaktiv sein und bei hover sagen "erst stoppen", oder es müsste eine andere Meldung geben.
> Stimmt.
> Ich kann keine Breakpoints setzen / toggeln wenn im draw() loop beim Starten noch keine waren ...

x 2) UX
Könnte man das toggln von Breakpoints auch direkt auf dem Margin links machen? Klick die zu beobachtende Zeile?

3) Bug
Wenn man einen Breakpoint auf eine leere Zeile setzt passiert einfach nichts ... stoppt dort nicht.

x 4) Bug
Ist ein String null und man doppel-klickt im Inspektor erhält man dort den String "null" als Inhalt, sollte besser leer sein? Könnte/sollte man null für null-Objekte in kursiv machen?

5) Bug?
Wenn man Zeilen mit Breakpoints löscht bleiben diese erhalten.

x 6) Bug
Der Inspektor bekommt nicht mit wenn man Variablen umbenennt.

x 7) Bug
Sketches mit P3D-Renderer laufen nicht: "package processing.opengl does not exist. …"
Probier eines hier: Standard mode->Examples->Libraries->opengl
7b)
Gleiches gilt auch für PDF Beispiele … kann es sein daß dir die "included Libraries" im Classpath fehlen?

x 8) Bug
Wenn man den Mode umschaltet bleibt der Inspektor offen

x 9) UX / Bug?
Der Zusammenhang von Updates der Info im Inspektor und dem Setzen von Breakpoints / Laufen lassen ist unklar. Ich nehme an die Info wird nur upgedated wenn man einen Breakpoint setzt und den Sketch gerade debugged? … daß die Info dann immer noch in grau sichtbar ist wenn man editiert ist verwirrend (aber ich verstehe daß sie auch nützlich sein kann). Könnte man irgendwie / irgendwo im Inspektor darauf hinweisen daß sich das nur erneuert wenn man gerade debugged?
Betrifft auch Punkt 6)

x 10) UX
Ich denke das "Debug"-Icon sollte einfach nur der "Run" Pfeil sein, so wie im Standard Modus. Das ist einfach und jeder versteht es sofort.
Die Breakpoints könnten ein Diamant/Raute sein und dann in der Margin als "<>" dargestellt werden. Hätte etwas mehr Volumen und ist leichter zu sehen von der Form/Leserichtung. … und es sieht ein wenig wie ein Auge aus.
Inspektor-Icon würde ich einfach ein "i" machen.

x 10b) UX
Die zwei Icons von "Set Breakpoint" / "Show Inspector" können ruhig richtig rund sein, gehören ja irgendwie zum Debugging-Vorgang. Die räumliche Trennung nach links/rechts finde ich gut.

11) UX
Befehl-R sollte "Debug" sein? … analog zu "Run"?

x 12) Bug
Breakpoints in Funktionen gehen nicht?

void setup () {
test();
}
void test () {
float xx = 1; // breakpoint hier
}

x 13) Bug
Beim Editieren von Array-Einträgen im Inspektor wird immer der erste Eintrag gesetzt, die anderen behalten ihre alten Werte.
String[] test = {
   "a", "b", "c"
};
void setup () {
   size( 200, 200 ); // breakpoint hier
   println( test );
}

14) Bug?
Sortierung im Inspektor auch innerhalb der Objekte ("Processing") möglich?

ISSUES:
* on debug quit running sketch
* on run quit debug
x on editor quit, stop spawned vms
1.6.2012
x clear log area when starting debug
x kill running prog when stopping or quitting
x only saved sketch is run in debugger?
5.6.2012
x line breakpoints need to monitor line insertions/deletions
x thread safety: events come in asynchronously
13.6.2012
x transform LineID to Breakpoint, possibly Breakpoint as subclass of LineID
* line highlight on first line doesn't move down
x clear bps on file open, new
15.6.2012
x line highlight interference with other line coloring methods
	x current line highlight
	x selecting
x we need a call stack window! (to know where we are)
x var inspector
	x tree icons
	x grey out when info not current (i.e. vm not suspended)
x line highlighting
	x DebugEditor should provide the functions for setting the current line, not Debugger
	x LineID is a design mess, need to restructure
/ VMDisconnectedEvent seems to be unreliable. likely synchronization problem.
x use resources/theme/theme.txt for highlight colors (current, breakpoint)
16.6.2012
x fast stepping exception: Only one step request allowed per thread
* toggling var insp. shouldn't focus var insp. window
19.6.2012
x NullPointerException when stepping into println (dbg_test.foo()) --> thisObject() was null (native or static mehthod)
20.6.2012
x sketch output window shows up after several draw() cycles, canvas updated even later
x fast continue: com.sun.jdi.IncompatibleThreadStateException
x fast continue: sometimes restarts debugger
* debug button highlight not working
	-> removes highlight when mouse moved (rollover event, p5 bug?)
x stepping from draw() ouside of visible code util draw() is hit again: com.sun.jdi.request.DuplicateRequestException
x hitting a breakpoint during a step + stepping again: DuplicateRequestException
-> policy: when breakpoint hit during step: cancel step, cause we stopped anyway (only finer grained)
* in stacktrace indicate if in native or static method
x add/rem a bp on the current line: messes up line highlight colors (-> color stacking system!)
x debugging w/2 editors open, focusing second (empty) editor just after hitting debug on first:
	Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: Bounds out of range: 32,47 [32]
	at processing.app.syntax.JEditTextArea.select(JEditTextArea.java:1193)

	at java.awt.AWTEventMulticaster.mouseDragged(AWTEventMulticaster.java:302)
28.6.2012
x disallow stepping into invisible code
* rethink: isPaused() vs. isBusy()
x remove auto breakpoints
* can't set breakpoint in a classes constructor?
3.7.2012
x can i make a modular Editor? (no matter how ugly?) -> no
x gutter fg color, bg color, per line. general bg color, trennlinie?
! stepping out of print(), println() returns to the same line
	-> NullPointerException, AbsentInformation + VMMismatchException when restarting dbg
/ change logger console format to something more readable
x allow setting log-level
5.7.2012
x sporadic while switching tabs (breakpoint hits,…):
	java.lang.ArrayIndexOutOfBoundsException: 344
	at javax.swing.text.Utilities.drawTabbedText(Utilities.java:132)

	at com.martinleopold.mode.debug.TextAreaPainter.paintLine(Unknown Source)
6.7.
* implicit stepping (invisible code) updates var inspector
x scrolling in vi when debugger stopped: com.sun.jdi.VMDisconnectedException:
	-> possible error in VariableNode implementation
	-> not occuring anymore (13.7.)
x second debug session doesn't work in some cases(VMEventReader quit on VM disconnect)
	happens when completely stepping out of setup()
x breakpoint marker remains, when opening new file
x contents of Animal a show up double (dbg_test)
* stepping out of setup doesn't stop in draw() (should it?)
11.7.
* VMEventReader should reset things too, on disconnect? (to avoid invalid states…)
* stepping into constructors, lands at closing bracket of constructor first
* sorting of processing node (appears first)
x folder icon not greyed out
x make editing values fail safe.
	-> fails when things happen while editing
x handle String quotes
	x show strings without quotes
	/ or: remove quotes when going into edit mode
12.7.
x save and export highlight the wrong buttons
13.7.
* current line hides underlying breakpoint
17.7.
* keyboard shortcuts
	set breakpoints
x null value in italics
* continue, step should do nothing when no dbg session is active
x debug button should do nothing while debugging
x debug mode has no core libraries…, examples
18.7.
x override buildModeMenu() in Editor, instead of manual menu creation.
/ when the variable inspector window is small, expanding a node by double click will make the selection jump.
	-> this is a feature (auto scroll on expand)
* debug doesn't properly restart the session. stopDebug() needs to wait for vmdisconnected

QUESTIONS:
* p5 alpha errors
	* file menu takes a long time to open the first time
	* <Error>: CGContextGetCTM: invalid context 0x0
x translate: sketch line numbers --> after pre/Users/mlg/Documents/NetBeansProjects/DebugMode/TODO.txtprocessing
x line background color
x how to extend p5 classes when all i want is change one member to a subclass


REQUESTS:
* JavaBuild/Compiler : allow custom compiler flags, especially -g (generate debug info)
* switch to tab by name: Sketch.java: make public: protected void setCurrentCode(String findName)
* Editor: method to clear console. without subclassing (console is protected)
* Editor: method to get caret line, without using getTextArea().getCaretLine() (for future releases that won't use JEditTextArea)
* JEditTextArea: allow setting TextAreaPainter. (e.g. using a factory method)
* JEditTextArea: make ComponentHandler, MouseHandler, DragHandler protected
x Editor.java: allow setting TextArea without overwriting class and copying/modifying constructor. copying the constructor is not easy due to protected/private fields..
    --> factory method
* switching modes doesn't produce a windowClosing() event at the editor. (need to override dispose() instead)


OBSERVATIONS:
11.6.2012
+ notice the janus head
	+ design iterations
	+ & implementation grind
14.6.2012
+ extensive todo and log ftw
+ public repo is kinda rewarding
+ dev methodology
	+ quick prototypes
	+ roughly implement critical features
		+ quickly see if/how they work together
		+ good api design
		+ better have all hi-priority features 50% done than some random ones at 100%
	+ iteratively flesh out and refine
	+ top down view on design



SYMBOLS:
* … todo item
x … done item
+ … simple enumeration (no todo)
/ … deferred todo
? … not sure about doing this
! … important todo
