Revision History

Version 3.4.2 (March 12, 2023)

  • Flowgorithm can now read files that contain extended Unicode characters (e.g. emojis). Beforehand, the system would raise an error.
  • The Kotlin Programming Language is now supported by the Source Code Viewer.
  • The language icons used in the Source Code Viewer were improved. In particular, they shouldn't be "cut off" on the bottom.
  • Made some changes to Java generated code.
  • Bug fixes:
    • Source Code Viewer wasn't converting the expressions on Write Shapes.
    • In the Source Code Viewer, if a custom program template was loaded, the screen wasn't being updated (until the window was resized).
    • C# generated code, in the Source Code Viewer, used the wrong data type name for Boolean.

Version 3.4.1 (January 9, 2023)

  • The Auto Layout will only resize the Main Editor Window if (a) there are more than one open window or (b) a window closes. Beforehand, it would resize the main window anytime the program was executed.
  • Bug fixes:
    • Sometimes the application was interpreting a number incorrectly on different cultural settings (using a comma rather than a period to represent the decimal point). The system is now locked completely into the computer science period notation.
    • The Console Window was causing a crash if minimized.

Version 3.4 (January 5, 2023)

  • Console Window was cosmetically improved.
    • The 'Enter' button is now smaller and contains a mouse-over tooltip.
    • The bottom input box and button will now appear correctly on the right-to-left languages.
  • The contextual pop-up menus (such as the Add Shape Menu) were improved. Before, when the pop-ups were deselected, the main window would drop in the Z-Order.
  • Multiple monitors
    • When using multiple monitors (with an extended desktop), the pop-up menus (Add Shape, Copy, etc....) will now appear on the correct monitor.
    • The Auto Layout feature will select the monitor that contains the main window. The other windows should now resize properly to it.
  • Colors
    • Added an "Apply Color Scheme to All Windows" button to the main toolbar and the main menu. This will allow users to quickly toggle between these two options.
    • The toolbar icons used to represent colors were updated.
    • The file icons for color schemes were also updated.
  • A "local clipboard" was added. Beforehand, the system always used the Windows clipboard. Unfortunately, through emulation, it doesn't always work. So, the local clipboard will be used in this case. This is invisible to users.
  • Flowgorithm can now read files that contain extended Unicode characters (e.g. emojis). Beforehand, the system would raise an error.
  • Bug Fixes
    • Fixed a bug in the Source Code Viewer. The C++ generated code was incorrect for passing arrays as a function argument. Special thanks to Thomas Takach for reporting it.
    • Fixed a few mistranslations for Polish. Special thanks to Tomasz Biliński for reporting it.
    • Fixed a few mistranslations for Portuguese. Special thanks to Nuno Queirós Rodrigues for reporting it.
    • Fixed a input flaw in the Console Window. It was possible to enter a real number for an integer variable (and the variable would act like a real).

Version 3.3.1 (August 17, 2022)

  • Hungarian translation was updated! Bernát Péter sent an updated version of his translation
  • Afrikaans translation was updated! E.J.P Kotzé sent an updated version of his translation.
  • Fixed a cosmetic bug where two successive comments are not aligned.

Version 3.3 (August 9, 2022)

  • Very minor tweaks - all of which are nearly invisible.
  • Source Code Viewer
    • Improved the JavaScript generated code. The code wasn't casting the input from the keyboard using Number() or Boolean(). Special thanks to Alexsander for letting me know.
    • Improved the C++ generated code. The code wasn't including <iomanip> if ToFixed() was defined. Also, the constant M_PI was misspelled (lowercase m). Special thanks to Misheel Tubshinbaatar for letting me know.
  • The Choose Color Scheme window will never apply the color scheme to itself. This will allow the user to select a new scheme even if the current one makes text unreadable. For example, the user could create a scheme with a black background and black text.
  • The disabled text color, in the menus, is now created by the application rather than relying on Windows.
  • Many of the function-key mappings were changed. Now, F9 - F12 will open the Variable Watch, Console, Turtle Graphics, and Source Code Viewer windows respectively.

Version 3.2 (July 28, 2022)

  • Bug fixes:
    • Any edits to the program will cause it to stop. Before, it was possible to edit a program without stopping it (under a very specific situation).  This resulted in an exception being thrown.
    • If an error occurred when the program was not in full-run mode, it caused as rather terrible bug.
    • When exporting a bitmap image, a line was being drawn on the very top of the image.
  • If the Run button is pressed on any of the child windows, the Z-order will not change anymore. This was an annoyance for users.
  • More menu items are now disabled when a program is running. These are features that should only be used if the system is idle.
  • In the Choose Color Scheme Window, the "apply scheme to all windows" was moved under the schemes list.
  • Source Code Viewer
    • Lua generated source code was improved.
    • C# generated source code was improved.
    • Python generated source code improved for turtle graphics. When the turtle moves home, Python will draw unless the pen is up.

Version 3.1.4 (July 16, 2022)  - Minor update

  • The scaling of the new windows were fixed. This is a minor GUI flaw where the windows were not as large as needed.
  • The icon were updated to contain higher resolution images. They should look far better than before.

Version 3.1.3 (July 12, 2022)  - Minor update

  • The Choose Color Scheme was made slightly bigger.
  • The Chinese translation was updated slightly. - special thanks to Janus She.
  • An "clear window" button was added to the Turtle Graphics Windows. This will allow instructors to clear the screen for presentations.
  • The Auto Layout feature was improved slightly.

Version 3.1.2 (June 27, 2022)

  • Fixed a bug with functions. The return variable name wasn't setting correctly. Special thanks to Roberto Atzori for reporting it.

Version 3.1 (June 26, 2022)

  • Catalan translation was updated! Roger Calders Jordana sent an updated version of his translation.
  • The windows are now automatically brought to front when Run or Step is selected.
  • Minor GUI tweaks:
    • Updated the Export to Vector window. It how now displays two radio buttons for EMF and SVG. These aren't really necessary since the dropdown on the file dialog allows either to be chosen. However, it does make it easier to choose an option (or, at least, know there are two available).
    • Updated the icons.
  • Program templates improved
    • New! Python code now generates valid Turtle Graphics and files. Special thanks to Damian Burrin for his help.
    • IBO source code was updated. Variable names are now capitalized.
    • Lua source code was updated. It now generates valid file IO code.
    • C# and Visual Basic .NET was updated.  It now generates valid file IO code.
    • All templates now contain a comment indicating if they will wont produce valid Turtle Graphics and/or file IO code.
  • Bug Fixes:
    • The Edit Function Window wasn't allow changes to be applied (and could cause an error). The bug shouldn't have made it into production. Special thanks to Ian Hollender for reporting it.
    • The Turtle Graphics window wasn't drawing the full line if the turtle moved forward and then immediately backwards. The bug was caused by (quite incorrectly) merging the drawing commands. Special thanks to Petr Vaněček and Roberto Atzori.
    • The Source Code Generator wasn't producing valid code. It was a rather careless mistake on my end. Special thanks to Damian Burrin.
    • There was a bug when exporting vectors that, sometimes, called the alignments to be off slightly.

Version 3.0.1 to Version 3.0.3 (June 20, 2022)

  • Fixed a few translation errors and a bug - special thanks to Roberto Atzori!
  • Various minor (and nearly unnoticeable) tweaks.

Version 3.0.0 (June 18, 2022) - Major Update

  • Added support for Latvian - Special thanks to Aldis Bērziņš.
  • New! Turtle Graphics were added. Flowgorithm can now display Turtle Graphics. This is similar, and inspired by, the classic LOGO Programming Language. Students will be able to use programming concepts to create images.
  • New! Basic file I/O support was added. Flowgorithm can now read (and write) basic text documents.
  • The Variable Watch Window was revamped.
    • New! The window can now display the stack. This will be helpful for teaching students about function calls, recursion, and, possibly, the concept of activation records.
    • New! The window can now display labels that designate the source of a variable. It will put variables into groups labeled "parameters" and "local variables".
  • Color schemes were improved.
    • New! Color schemes can now be applied to the entire application. So, Flowgorithm can have a dark theme, light theme, or any color - for that matter. The picture below shows Cyberspace color theme applied to all windows..
    • Updated. The Color Scheme Editor was updated to handle the new colors (for fields, controls, etc...)
  • New! Flowgorithm can now automatically arrange the windows. This is similar to the Arrange Windows button, but will activate automatically anytime a window is opened or closed. The toggle button is located on the main toolbar.
  • The application now has 4 run speeds: full, fast, medium, and slow. The speed "full" acts the same as "fast" did in Version 2.
  • The Breakpoint Shape now supports conditional expressions. In the last version, the Breakpoint Shape always pauses execution. The new version can now use a conditional expression - if needed.
  • Printer Window was revamped. The user can now select multiple functions to be printed.
  • The About Window was revamped.
  • Export Image/Vector Windows were revamped. The controls were rearranged.

Version 2.30.3 (August 1, 2021) - Minor update

  • The Variable Watch Window, if opened from the Console, will automatically align to the right of it.
  • The Console, Variable Watch, and Source Code windows now display quicker - especially when using the Layout Windows feature.
  • Most Recently Used List is now updated on save. The Most Recently Used list is located in the File Menu
  • Tools Menu was reordered slightly. They now match the order of the toolbar icons. This is completely cosmetic and I doubt many will notice.
  • The input box in the Console Window was updated slightly. The size of the text now zooms with the output panel.
  • Bug fix: The Variable Watch Window was reporting an error if it was minimized. The bug, while annoying, didn't cause the application to crash.

Version 2.30.2 (July 21, 2021) - Minor update

  • The Console Window now displays all numeric results in non-scientific notation.
  • The Main Window and the Variable Watch Window will scroll or zoom depending on the Control Key. If Control is pressed, the mouse wheel will cause the windows to zoom in or out. If unpressed, they will scroll vertically as normal.
  • When the Variable Watch Window is opened, it now aligns just right of the Main Window.
  • Updated the toolbar icon for the Variable Watch Window. This version contains the text "x=" and is designed to look different than the Source Code Viewer icon.
  • Minor bug fix: The Source Code Viewer updates a tad better if flowchart shapes are changed.

Version 2.30.1 (July 20, 2021) - Bug fixes

  • This release fixes a number of bugs. Special thanks to Petr Vaněček for his help. He pointed them out and helped test the fixes.
  • Bug: Literal real numbers were not working. This was the classic comma-vs-period issue appearing again.
  • Bug: Console Window was allowing a comma-decimal number to be entered.
  • Bug: The templates were not casting when storing a real into an integer. Also, real integers (when small) were not displaying correctly. It affected the following templates.
    • Java
    • C++
    • C#
    • Scala
    • Pascal

Version 2.30 (July 19, 2021)

  • The main menu was re-arranged. A new menu item called "Appearance" was created. All the features that affect how the flowchart/application appears were moved here.
  • The mouse scroll button will now zoom the Main Window and Variable Watch Window (i.e. the graphical windows).
  • Control-0 (zero) will now reset the zoom in the Main Window.
  • Application scaling can now also be changed using the keyboard. Control+Shift+Plus will increase the scale and Control-Shift-Minus will decrease it.
  • The Error Window will now automatically wait (for 5 seconds) if the same exact error & shape occurs twice. This is designed to force the student to actually read the window rather than just clicking "Ok".
  • Added an "Import" button to Function Manager Window. It will add all the functions from another Flowgorithm program file. It's similar to the concept of "include" except the functions will be added to the current program rather than being linked.
  • Fixed a bug that affected Breakpoints. If a breakpoint was the first shape in program, it would cause the system to crash. Special thanks to Petr Vaněček for reporting it.

Version 2.29 (May 29, 2021)

  • Added support for Tamil - Special thanks to Guru Priya Jayasankar.
  • The Console Window can now visually show when an Breakpoint was reached. This will give students a visual cue that their program has been paused.
  • Some toolbar icons were rearranged for consistency.

Version 2.28 (May 7, 2021)

  • Added support for Afrikaans - Special thanks to Ernst Kotze.
  • The GUI for "checked" toolbar buttons was changed. Before, the system was simply drawing a blue rectangle around the button. The updated version displays a constant light-blue box.
  • Various changes were made to make the software work better under Mono and other forms of emulation. In particular, some of the windows, what are causing a crash, were fixed. Hopefully, it works far better now.
  • Miscellaneous cosmetic tweaks.

Version 2.27.2 (April 11, 2021)

  • The Hebrew Translation was updated - Special thanks to Zeev Kotzer. The new version works better on Linux and Macintosh under emulation.
  • Gaddis Pseudocode was updated. It was using parenthesis for array access rather than square brackets.
  • Improved the Auto Pseudocode feature. When using the Source Code Viewer, the "auto" pseudocode is created directly from the current translation. It wasn't taking into account newline characters and was displaying text incorrect (if they were present).
  • Some, very minor, cosmetic changes.

Version 2.27.1 (April 9, 2021)

  • The Run/Step/Pause/Stop toolbar buttons were updated. The behavior of the buttons (when they are enabled) is now far more consistent.
  • Added a Download Color Scheme icon to the Color Scheme Editor.
  • Made some various cosmetic changes (that most won't notice).

Version 2.27.0 (April 4, 2021)

  • Added support for Hebrew - Special thanks to Zeev Kotzer.
  • The application, when first executed, will now attempt to set the translation to the computer's current culture. This will only happen if the application's registry settings are not set (both current user and local machine).
  • The Download Color Scheme Window was improved
    • The tree now follows the right-to-left logic of languages such as Hebrew, Farsi (Persian) and Arabic.
    • A bug was fixed that caused text to be incorrectly displaced for some dialects of languages.
  • Change Translation window was improved with a header icon and description. To make the graphic look decent against a blue background, the colors of the icon were changed.
  • Bug Fixes:
    • Fixed a bug that occurred when the system was running in slow/medium speed. When the stop button was pressed, the remaining buttons were not enabled correctly. Thanks to Jose Cardenas for reporting it.
    • Fixed a bug that affected expressions. The system was incorrectly reporting an error if an array was used from within an parenthesized expression. Thanks to Jose Cardenas for reporting it.
    • Fixed a bug in expressions. When a unary minus was used after a comma, the system was reporting a syntax error. Thanks to Ilya Volobuev for reporting it.

Version 2.26.0 (March 31, 2021)

  • The Download Color Scheme icon was changed. This is a simple cosmetic change.
  • Color Scheme Download window was made larger.
  • The Color Scheme Editor was improved.
    • Buttons were added for undo/redo
    • The Picture Preview box is far larger now.
  • Bug fixes:
    • Fixed a (very hard to find) bug that caused the application to hang when executed in a VM. Special thanks to Zeev Kotzer to helping me track this down!
    • Right-click on If-Statement connector (the little circle) was causing the application to crash. Special thanks to Deanna Wilborne.
    • When running the application on medium or slow speed, the program were automatically restarting. Special thanks to Deanna Wilborne and Marty Port for letting me know.
    • Precedence levels for Unicode operators wrong in a few cases.
    • The Source Code Viewer was not resetting the current line, if a new flowchart was loaded.
