Revision History

Version 2.15.2 (June 15, 2018)

  • Color Schemes can be dragged and dropped on the Choose Chart Style window. This window was also increased in side, slightly.
  • The various translations were updated to report an "Invalid File" rather than an "Invalid Program File" when an invalid file is dragged and dropped. The original translation dates back to when Flowgorithm only used one file type: fpgt. Now, it also uses color schemes and program templates.
  • Added some internal exception-handling code. The code handles situations when links fail to open correctly.

Version 2.15.1 (June 13, 2018)

  • Fixed a bug in Visual Basic .NET generated code. The Input Statement was calling the wrong function. Special thanks to Jon Bek.
  • The icon used to represent Visual Basic .NET in the Source Code Viewer was updated.
  • Several program templates were updated. The templates were incorrectly indicating that the Aligned/Hanging option was available.

Version 2.15.0 (May 29, 2018)

  • Program Templates were added! Templates are simple text files that the Source Code Viewer can use to generate code for any pseudocode and/or programming language. This means that Flowgorithm is not limited to the programming languages currently supported. Please see the documentation for more information.
  • Bug fixes:
    • Fixed a bug when occurred of Flowgorithm was closed while running. In this case, it was possible for the runtime engine to get stuck in an infinite loop and the application hangs (without a GUI). Special thanks to Daniel Ivan Escobar.
    • Fixed a bug in Visual Basic .NET generated code. The Source Code Viewer was ending a Module definition with an End Class rather than End Module. There were also some mistakes with generated functions. Special thanks to Jon Bek.
    • Fixed a bug in Python Generated Code. The Source Code Viewer was displaying {1) rather than the correct operand for concatenation. This was a careless typo. Special thanks to Dave Braunschweig.

Version 2.14.1 (April 1, 2018)

  • The Italian Translation was updated - special thanks to Roberto Atzori.
  • The Gaddis Chart Style was updated. The application was displaying the text "Function" at the top of each flowchart - which was a mistake.
  •  Auto Pseudocode was updated. For If Statements, with an false branch, the pseudocode no longer contains the "True" label line.

Version 2.14 (March 30, 2018)

  • Added Undo and Redo. The new feature will allow users to undo and redo changes to the flowchart.
  • New pop-up menu was added to the main window. The new menu is displayed when the background of the flowchart is right-clicked. It contains "Choose Program Style...", "Program Attributes..." as well as Undo and Redo (if available).
  • PowerShell generated code was improved. In particular, how text is used with Write-Host was syntactically simplified.
  • The icon used to represent Gaddis Pseudocode in the Source Code Viewer was changed. The update was designed to reflect the release of the 5th edition of his popular book: Starting Out With Programming Logic. The fruit on the front of the book changed from an apple to a plum.
  • Updated the logic that forces the Console Window to the top of other windows. Now, it will only be forced to the top if either #1 the window was first opened or #2 the user clicks "Run" at full speed. 
  • Added the Run, Step, Pause, and Stop buttons to the Source Code Viewer.

Version 2.13 (March 8, 2018)

  • Added support for Romanian - special thanks to Vlăduț Ilie.
  • Fixed a bug in Visual Basic .NET generated code. Call Statements weren't putting parenthesis around the arguments.

Version 2.12.2 (March 6, 2018)

  • The Source Code Viewer now remembers if you selected line numbers. This setting is saved so that, the next time the application is opened, it will retain its value.
  • The Function Manager now checks an function, on the list, after a single click.
  • Bug fixes:
    • Pascal generated code was improved. The generated code was in inserting a semicolon after every statement rather than just between them. In Pascal, the semicolon is a statement separator rather than a delimited. Some compilers allow it to be used as a delimiter, but not all. The generated code was also using StrToFloat rather than FloatToStr for concatenation. Special thanks to Dr. Richard Lui for his help.
    • In the Source Code Viewer, VBA (Visual Basic for Applications) was displaying the aligned/hanging option even though it doesn't apply.
    • IBO Pseudocode and Gaddis Pseudocode were not displaying the "end". This was careless mistake.

Version 2.12.1 (February 28, 2018)

  • Updated the title bar on the main window. Now, the system will display the name of the file, a dash, and then "Flowgorithm". This is consistent with how most applications use the title bar. The version, which used to be displayed as part of the title bar, now is displayed in the footer when the application first loads.
  • Made some cosmetic changes to the About Window.
  • Fixed a bug in the Edit Function Window. If the user tabs to the Return Type dropdown, the system wasn't enabling the Variable Name field. Special thanks to Nathan Todd.
  • Fixed a bug in the VBA (Visual Basic for Applications) generated code. I had failed to as the "As" clause to functions. Thanks to Nic Lightfoot for letting me know.

Version 2.12 (February 21, 2018)

  • Added support for Malay - special thanks to Husnil Khatimi Hussin.
  • The Italian Translation was updated - special thanks to Roberto Atzori.
  • When an error occurs, the window will now highlight the shape before displaying the error window.
  • Source Code Viewer:
    • Added "Auto Pseudocode". This pseudocode is generated by using the current translation. This means that, for example, if Flowgorithm is in Spanish, it will produce Spanish pseudocode. This is the case for all other languages: Korean, Farsi, Arabic, Italian, etc...
    • Added Smalltalk. Invented by Alan Kay, Smalltalk created the concept of Object Oriented Programming.
    • Added PowerShell. This is a scripting language, created by Microsoft, that combines concepts of Smalltalk, Perl, and .NET.
    • Incomplete shapes are were improved. When a shape is incomplete, empty fields will now contain the field's name. Each name is read from the current translation. So, for example, if the current translation is Spanish, then the incomplete fields will contain Spanish names.
    • The line numbers are now right aligned
    • VBA generated code was improved. Special thanks to Nic Lightfoot.
    • When source code is saved, the system will only used UTF-8 if a Unicode (non-ASCII) character is present. Otherwise, it will default to ASCII.
    • Greatly improved the generated code for: C#, Lua, Pascal, Perl, and Visual Basic .NET.
    • The last language used is now saved in the Registry.
  • Bug fix: If a number is used with the Len() function, the system was incorrectly specifying it needed a "number" rather than "string". Thanks to Roberto Atzori for finding this.

Version 2.11.1 (January 25, 2018)

  • The shape captions used in the Default (Descriptive) chart style are a bit more descriptive.
  • Source Code Viewer:
    • Some of the language names were translated better. In particular, the word "pseudocode".
    • The mouse scroll wheel wasn't working on the Source Code Viewer.
    • QBasic code, in the Source Code Viewer, left off the '#' for generated functions - such as ToFixed.
    • Some of the languages, in the language dropdown menu, weren't being translated properly.

Version 2.11 (January 15, 2018)

  • The Slovenian translation was updated - Thanks to Gregor Anželj
  • Source Code Viewer:
    • TypeScript was added.
    • Scala was added.
    • The window GUI was revamped! Each programming language is now represented using a unique graphical icon. The icon is used on the main toolbar and new dropdown menu. The "Aligned/Handing Brace" dropdown was also replaced with a graphical version. It will only be displayed when it is relevant (rather than just being disabled).
    • JavaScript code was improved. The generated code for Random last lacking the "Math." prefix and always used parenthesis.
    • The scrollbar behavior was improved. It is now disabled if not needed.
  • The Change Chart Style toolbar icon was updated (yet again).
  • The Clipboard popup menu now aligns to the left on right-to-left languages such as Arabic and Farsi.
  • The Comment Shape's maximum width size (before word wrapping) was increased slightly.
  • The "Pastel" color scheme was updated slightly - in particular, the shade of gray used for comments.
  • Program Attributes window
    • It now shows the date that the file was last saved. This is not an editable, but useful, field.
    • Pressing F4 from the main window, will now open the Program Attributes window.
  • Bug fixes:
    • Fixed a minor bug in the Color Scheme Editor. When an image file was opened, it remained locked (can't be moved, deleted, etc...) until the editor was closed.
    • Opening the Function Manager no longer marks the program as "changed".

Version 2.10 (November 22, 2017)

  • The Function Manager was improved. The new version allows entire functions to be copied. cut, and pasted.
  • Color Scheme Editor can now be opened with Control-E
  • Fixed a bug in the Color Scheme Editor. The effects the "dropper" tool. If a transparent area of a shape is clicked, the color would be incorrect. 
  • Fixed some minor tab-order issues.

Version 2.9.2 (November 9, 2017)

  • The Save-As feature, in both the Main Window and the Color Scheme Editor, works far better now. It will show the current name as a default.
  • Updated the Retro Computer color scheme.
  • Restored textboxes, that are used for expressions, to left-to-right for all cultures.

Version 2.9.1 (November 4, 2017)

  • Fixed a bug that effected in Right-To-Left languages.

Version 2.9 (November 3, 2017)

  • Added support for Korean - special thanks to Inkee Jeong.
  • New error message. When a function is used in an expression, it must have a return value. The new error message properly explains, to the user, what happened. Beforehand, the error was being handled by Type Mismatch. This wasn't particularly helpful.
  • Output Shapes were improved. Output can now include or exclude the newline character. This will give better control over output - and allow the "ASCII art" commonly used in beginning programming.
  • Color schemes were improved. The colors of the Comment Shape can now be customized. Beforehand, it used the same colors as the page.
  • A few built-in color schemes were modified.
  • Bug fix: When an error occurs, the system will show the shape that cause the error. Unfortunately, the system failed to do this if the error occurred in a different function (than the one being displayed)
  • Updated the About Window. The new version of the About Window was designed to maximum screen real estate. The old version was becoming far too large.
  • Minor updates to the Error Dialog and Message Dialog windows.
  • Minor GUI tweaks.

Version 2.8 (October 7, 2017)

  • Added support for Dutch - special thanks to Ralf Djojomoenawi & Sander Dol.
  • If a function is incomplete (missing its return variable), it will now display in gray.
  • The comment shape was updated. The left-side connecting line will always use the color of the rest of the lines. The idea is to prevent it from "vanishing" if the current scheme's Selection border color is the same as the background color. In addition, the preview image no longer displays the left-side connecting line.
  • Fixed a bug that occurred when a function, that doesn't return a value, is used in an expression. While the error message produced now isn't the best, it is far better than before.

Version 2.7.1 (September 16, 2017)

  • Fixed a bug in Python generated code. Empty blocks were not including 'pass' statements. Special thanks to Clive Long for reporting the bug.
  • The internal logic used to draw shapes was updated.

Version 2.7 (September 6, 2017)

  • Added support for Indonesian - special thanks to Abdul Kadir
  • The Polish Translation was updated - special thanks to Robert Gajewski.
  • Updated the logic used to show the Add Shape and Clipboard pop-up windows. Hopefully, this change will work better for those using WINE to run Flowgorithm on the Macintosh.
  • Fixed a bug where lines wouldn't "line up" on Comment Shapes.
  • The Color Scheme Editor now has a "copy" dropper that will copy all the attributes (text, fill, and border) from another clicked shape.
  • The colors used by Comment Shapes was redone. Now, both the text and border will use the page's text (label) color.

Version 2.6.1 (August 10, 2017)

  • The Console Window now responds to pressing F5, F6, F7, and F8. These are used to Run, Step, Pause, and Stop respectively.
  • The Italian Translation was updated - special thanks to Roberto Atzori
  • In the Color Scheme Editor, the image scrollbars work far better than before.
  • The graphic image, used the various shape edit windows, is better horizontally centered between the window's edge and the text.

Version 2.6 (August 7, 2017)

  • Added support for Farsi (Persian) - thanks to Vahid Baghi
  • The Declare Shapes can now support multiple variables. The user can list different variable names separated by commas.
  • File changes:
    • To accommodate older versions of Flowgorithm, the application can now save programs in 1.0 and 2.0 format. The current format is 2.6. The current version can still open any previous file version.
    • One of the redundant legacy fields, "variables", in the Declare tag, was removed. This was designed for forward compatibility with older versions of Flowgorithm (pre 1.7). Since Flowgorithm can now save to older formats, it is unnecessary.
  • The word-wrapping, used on shapes, was improved. Beforehand, the text could, sometimes, fail to be vertically centered. The new logic both resolves this problem and wraps based on syntactic elements (such as operators).
  • Printing was improved:
    • The window now opens the Print Common Dialog window. This allows the user to find printers, set advance features, and much more.
    • An icon for portrait & landscape were added.
    • Printer settings are now saved to the registry. This includes the printer's name, landscape, and margins.
  • Color Scheme Editor:
    • Added a Save-As button.
    • When a new color scheme is created, the hover color of the 'line' is now set to orange. Before, it was white.
  • The system can catch, and report, Overflow Errors far better than it did before.
  • The Console Window now has a limit on the number of items in the buffer. This prevents the system from running out of resources if (as an example) a loop prints from 1 to a million. No errors are caused. Early items are simply removed.
  • The Turkish translation was updated.
  • The Add Shape pop-up menu and Clipboard pop-up menu work better than before. They should appear quicker and properly return focus to the main window when closed.
  • When the flowchart background is double-clicked, the Program Attributes window will open. Before, the user would left double-click. It has been changed to right double-click to avoid it being opened by accident.
  • The message window was updated. In particular, the padding between graphical elements was increased.
  • Bug fixes:
    • The thumbwheel on the mouse was moving the scrollbar, but not updating the window.
    • On the Gaddis Chart Style, the assignment caption had extra spaces.
    • The Console Window no longer aggressively sets its Z-Order. Before, anytime the window received output, it would force itself on top of all the other windows. This made it difficult to stop the program from the Main Window.

Version 2.5.4 (June 16, 2017)

  • Fixed a bug in the Variable Watch Window. It was not translating the label "Main" into the current language.
  • Double-clicking on the main window's background will now open the Program Properties window. This was an old feature that was removed before the shape selection object was updated. However, it wasn't re-enabled until now.

Version 2.5.3 (June 15, 2017)

  • Updated an even better translation for Italian - Thanks to Roberto Atzori
  • Improved the Color Scheme Editor. The internal logic, used to determine if a color scheme was changed, was improved.
  • Fixed a bug in the Color Scheme Editor. The Open Image dialog was not being translated.
  • The "If' Shape appearance was improved. Padding was added around the text - so the line and text should not overlap.
  • Some miscellaneous changes to windows - minor and probably not noticeable.

Version 2.5.2 (June 14, 2017)

  • Updated the translation for Italian (fixing my Google Translate text) - Thanks to Roberto Atzori
  • Fixed a bug that prevented the key combinations of Control+ and Control- from zooming the main window.

Version 2.5.1 (June 12, 2017)

  • Updated the translation for Traditional Chinese - Thanks to 黃昕暐 (Shin-Wei Hwang)
  • Updated the Color Scheme Editor. Now the editor, opens the current scheme. It also applies any changes to the main window.
  • The icon used for Traditional Chinese (the Taiwanese flag), was updated with a better version.

Version 2.5 (June 8, 2017)

  • Added support for Traditional Chinese - Thanks to 黃昕暐 (Shin-Wei Hwang)
  • Customized Color Schemes were added.
    • Color schemes can be created and edited with the use of a new Color Scheme Editor.
    • The files are saved using the .fclr extension.
    • To make it easy to load schemes, "open" buttons were added to the Print, Export Bitmap, Export Scalable Graphics, and Change Chart Style windows.
  • The Variable Watch Window now graphically displays the name of the current function.
  • Chart preview images (used in the Print, Export Bitmap, Export Scalable Graphics, and Chart style) were improved. They are larger, contain an additional shape, and show text on the shapes.
  • Auto-scrolling, used when the window automatically scrolls when selecting shapes, works far better now.
  • Window activation works better now. Beforehand, if the user chose to show a window, but it was minimalized, it stayed minimalized. Now, the window will normalize.
  • Source Code Viewer:
    • PHP was added. It contains both the "hanging" and "aligned" brace formatting styles.
    • Apple Swift 3 was added. Swift 2 was retained.
    • Fixed in a bug in Python generated code. The code was using 'true' and 'false' rather than 'True' and 'False'. Thanks to Jon Rios for reporting this.
  • The "Traffic" color scheme was modified to have a blue background. The original color scheme can still be downloaded on the Color Schemes page.
