Computator.NET v2.2.0 Official Release

Computator.NET v2.2.0 - More usable than ever!

This is the first release marked as stable in Computator.NET history. Although there are still bugs, we are more and more confident that we are releasing SOLID and usable software. With focus on user-experience we delivered better look and feel, especially in high DPI scenarios and the most requested features. Bugs and inconsistencies were fixed and "quirks" removed. We have also started nonofficial support for Linux and Mac OS X.

Look and feel

• Resolved countless DPI scaling issues (issue #37, #16)
• Fine-tuned user interface, so it will scale better and look nicer
• Fixed bug with tabs in scripting not showing up correctly on small windows size
• All icons and logos should now look brighter as they do not use transparency anymore
• Numerical input is made way better, ScientificNumericUpDown is used everywhere - this makes NumericalOutputNotation supported in defining input through controls (#34)
• Installer should now show correct images even on Windows XP

New features

• Cases like 2²x, 2(x+1) and (x+1)x are now handled correctly for multiplying
• Added handling of modulus notation (absolute value) - example |x+2|=|cos(y)|, including superscript (#11)
• Functions&Constants menu has now option to show function details on right mouse click just like it was before version 2.0
• Updated GSL to version 2.3
  • improved precision in Bessel K0/K1 near x = 2 (#47401)
  • bug fix in convergence check of hypergeometric 2F1 function (#45926)
• Added an option in settings to declare behavior in case of calculations error - ReturnNAN means return not a number in case of error in calculations and ShowError means app will show error dialog
• Linux and Mac OS X are now unofficially supported (started support for Mono), current version is still not stable enough but compiles and starts properly (issue #25)
• Way better logging, changed logging library to NLog (#36)
• Way better settings, based on binary serialization instead of AppSettingsBase class, made descriptions, names and categories for Settings types (#57)
• Way better Polish translation

Fixed bugs

• TSL compiler now handles correctly functions with superscript characters in function name (this finally makes all unit tests green)
• Fixed Hypergeometric functions (will return NaN instead of showing error unless ShowError is defined in setting CalculationsErrors) (resolved issue #17)
• Fixed underflow error for MathieuMc(1,-20,2.04081632653062,-100), MathieuMc(1,-20,x,-100) (#8)
• Recreated function logGamma with fixed all errors (#12)

Quality

• GSL is now statically linked so Visual C++ Redistributable is no longer needed
• Introduction of IoC Container (Unity)
• MVP implementation improved - forms and views now take controls from constructors, singleton model has been dropped, presenters now use ISharedView state representing one SharedViewState instance but not singleton, same for error handler etc - all the dependencies are now injected
• Command pattern usage improved - all dependencies for commands are now injected, so every command is 100% unit testable
• Added code coverage calculations for each build in CI
• Moved to NET46
• Windows XP support is considered for removal in coming versions (right now it is still supported by having separate NET40 build and installer)
• Build process is optimized - Release is faster and Debug is safer
• Some assembly informations are now shared for all projects
• Introduced continuous integration - AppVeyor and Travis

Computator.NET v2.1.0 beta Official Release

Computator.NET v2.1.0ß - making it more stable

This release is a another milestone in Computator.NET history. After moving to github we encountered dozens of bugs, some really serious and only a few new features requests. So it was obvious that our work should focus on bugfixing and making it more stable.
There are over 50 serious fixed bugs and even more less serious, some are not fixed yet but included in BUGS file. In addition there are some nice new features - most of them are focused on making TSL the standard language for computations - which itself can be seen as bugfixing TSL desgin.

New features

• + Bug reporting now opens link to github project issues page

• + ScientificNumericUpDown supports now NumericalOutputNotation from settings

• + TSL finally supports anything with valid variable format raised to any power with superscript notation (before it worked only for x,y,z,i now it works for anything that looks like a variable or constant eg _niceVariableNameᶜᵒˢ⁽ˣ⁾˙ˢⁱⁿ⁽ʰᵃˣˣˣˣ⁾ is working just like it should) (it enabled us to simplify a lot of code in other places)

• + TSL handles now full mathematical multiplying notation like 2x means 2*x

• + Chart3D and ComplexChart now supports printing and printpreview

• + All charts now use the same SaveImage dialog with option for many different image formats, which makes exporting a chart nice experience

• + New special symbols for better looking exponents

• + You can now use functions with many parameters in exponents (added comma superscript symbol compatible even with Win XP)

• + GSL can now be initialized with second method if first doesnt work

• + Added exception handling for GSL initialization and logging all the errors

• + Installer will now always install Cambria font, Consolas font and TSL examples files

• + EditChart3DWindow can now edit chart area values properties

• + GSL updated to version 2.1

• + Added solve(m) function for solving linear equations in matrix representation

• + Added LU, QR, Cholevsky, Evd, Svd and GramSchmidt matrix decompositions

• + Added more TSL examples including matrix solving and decompositions

• + Introduction of SharedViewState representing shared state of application for various uses

• + Finally introduced async and await for longer running background tasks like ComplexChart drawing - this fixes UI freezing

• + ExponentMode menu command works now for AvalonEdit code editor too

• + Installer now includes .NET 4.0 KB2468871 update for async and await support on .NET 4.0

• + Due to compatibility issues installer now includes all needed redistributables instead of just downloading them

• • Constants and functions not presented in functions.xml are now included in menu by their data from autocomplete

  Bugfixes

• = Fixed bug in binding exponent mode from edit menu to exponent mode in code editor

• = Fixed bug in chart edit property window causing ComplexChart to not redraw after changes

• = Fixed bug in ComplexChart GreaterIsLighter and GreaterIsDarker methods when NoCountourLines selected causing pitch black chart in GreaterIsLighter mode and not accurate chart in GreaterIsDarker mode

• = Fixed visual bug in polish version of "for values" label (wrong placement)

• = Fixed minor bugs and typos in dialogs like about, features etc (for english and polish versions)

• = Translated all previously missing elements in polish version

• = Fixed very important bug in ScriptingExtensions - all outputs in application are now culture invariant (not being culture invariant before caused some output in non-english versions to include comma (,) instead of dot (.) for decimal separator which caused bugs when output was used in input - because we always use decimal dot (.) in TSL for decimal separation)

• = Fixed important bug in ToMathString(this double) method from ScriptingExtensions, in MathematicalNotation exponent was in format just like in engineering notation (eg we had 10⁺⁰²³ instead of just 10²³)

• = Fixed important bug with matrix unable to be created if it had any sqrt(real) functions inside (this was caused due to sqrt(real) returning dynamic, fixed by creating new matrix construction method)

• = Fixed yet another (this time minor) bug in output - i or -i was resolving to 1·i or -1·i instead of just i or -i

• = TSL Compiler's regular expressions are now compiled at the start of the program, evaluation of user's code and expressions should work a lot faster now

• = Fixed bugs in root(x,n) and pow(x,y) functions, now they can return complex even for real parameters and root is finally working correcly for odd n

• = NativeCompiler refactorization, errors and warnings translated to polish

• = 'dynamic' functions (sqrt(real), root(n,x) and pow(x,y)), generic parameters/arguments and 'params' parameters now appear correctly in autocomplete

• = Minor bufixes and changes to TSL Compiler allowing more freedom to user in defining things

• = Bug in read() functions fixed - input is now CultureInvariant just like it should be

• = Moved Localization to Computator.NET.DataTypes, which makes localization of all the Computator.NET components a lot easier

• = Fixed bug in plot(f(x,y)) TSL function which made user unable to change chart area values (xmin,xmax, ymin, ymax)

• = Unified Chart (edit) menus in GUI and scripting (they are now inside their own class, reusable), removed any code redundancies and errors (in chart3d in scripting export was generating invalid names)

• = Cleanup for Chart3D

• = Fixed bug in ScientificNumeriUpDown with Value sometimes over decimal.MaxValue or under decimal.MinValue

• = Fixed bug with GSL library not loading - installer will now always install Visual C++ Redistributable for Visual Studio 2013 (MSVCRT120.DLL, used by gsl.dll and cblas.dll) if needed

• = Fixed bug with application not starting on Windows XP because of icon -> now icon is not compressed, still 256x256

• - Removed option to select a rectangular area using the mouse right click over Chart2D

• = Fixed important bug in ExpressionEvaluator - lambda expressions were interpreted as implicit functions which was preventing user from using them

• = Fixed bug in autocomplete, it was comparing substring including whole signature of function, now only uses name

• = Fixed important bugs causing autocomplete to not show in exponent

• = Fixed some bugs in HypergeometricU, Hypergeometric1F1 special function

• - Removed unused argument n from function EllipticD(φ,x)

• = Mathieu functions should be a lot faster now, they are called directly now as a functions - not by passing a reference interop struct type

• = TSL now supports whitespace characters in exponent

• = Fixed bug in TSLCompiler related to multiple nested parenthesis with exponents

• = Fixed bug ctrl+T does not create a new tab in scripting and custom functions when focus is on code editor

• = Fixed bug with localization - now even top menu is reloaded if language has been changed

• = Fixed all bugs and enhanced domain for En(n,x) function

• = Introduced ∞ symbol for Infinity

• = Fixed all known bugs with changing editor type with opened documents

• = Fixed minor bugs in directory tree / solution explorer

• = All windows and dialogs of app are now behaving consistently with what they are (resizing, icons, look etc)

• = MVP pattern implemented for UI

• = Command pattern implemented for Top Menu and Toolbar Menu

• = GSL is now compiled with Visual Studio 2015 Update 2, installer includes Visual C++ Redistributable for Visual Studio 2015 Update 2

• = Fixes in functions categories, fixed inconsistency between functions.xml signatures and assembly
