Release 0.4.3: Graphics / plotting stabilization

[c3d]

New features:

• Parametric and polar curves (Parametric and polar plots #364)
• Function, Polar and Parametric can be used to plot from stack (Add separate PlotFunction command #339)
• ResetModes command (Add a ResetModes command #315)
• Add Clip command to control screen clipping rectangle (Add command to set and reset graphic clipping #313)
• Separate "graphic" mode (Graphics mode with suspended refresh #342)
• Add CAS numeric / symbolic flag (Add CAS flags #346)
• Accept functions that use the independent variable from PPAR (Plotting should work when using independent variable from PPAR #352)
• Source code comments (Comments in the source code #94)
• Add a demo state file (Add a demo state to the release #355)

Bug fixes:

• Scaled coordinate system was upside down (DrawPlot is plotting upside downs #331)
• Skip errors during function plot (Error during plotting interrupts the plot #329)
• Make ->Num work on equations (The ->NUM function does not work on equations #345)
• Fill glyph background over whole height of font (Drawing text in reverse color gives strange results #335)
• Refresh screen correctly after drawing axes (Refresh of screen after DRAX #328)
• Refresh screen better during plotting (Refresh problem during plotting #337)
• Save line width, foreground and background in state (Line width is not preserved in state #338)
• Correctly skip closing parentheses for "legacy" complex syntax (Parsing of complex numbers with parentheses does not seem to work #336)
• Workaround QSPI fast-read bug on DM32 to avoid crashes (DM32: Crash in sparse glyph rendering #304)
• Parsing pi in equations as built-in command, not symbol (Parsing pi in equation results in symbol #347)
• Do not leak errors during plotting (The draw command leaks errors that were encountered #354)
• Missing trailing space when rendering lists (List rendering: regression (missing trailing space) #361)
• Correct parsing of based integer at end of a list (Error if there is no space after based number in list #362)
• Emit error if missing variable in for next (Parsing for next adds garbage to the loop #363)
• Fix backward conversion from radians for fractions (Conversion of fraction angles from radians is bogus #365)
• Execute local variables when evaluating them (Evaluating a local variable should execute it #366)
• Fix 'EXIT' key to interrupt program in Wait (In simulator, EXIT does not interrupt programs #356)
• Convert coordinates from based numbers as unsigned (Pixel-positioning text display goes blank beyond half of screen #368)

Enhancements:

• Switch to 32-bit graphic coordinates (Drawing coordinates should be 32 bit #334)
• Clip lines more efficiently to clipping rectangle (Clipping of lines to clipping rectangle #332)
• Draw axes by default when plotting (The Draw command should draw axes by default #353)
• Change position of type in connstructors (Change the position of id in constructors #343)
• Add 'save' internal utility to save/restore scoped variable (Add 'save' utility to save/restore value of variable #349)
• Optimize special case of polar addition / subtraction with same argument
• Updated PNG / SVG files for overlay
• Disp goes to new line at original horizontal position (The disp function should return to newline at original offset #358)
• Add -m option to pass memory size to simulator (Add option to set memory in simulator #367)
• Make symbol comparison for dependent variable case-independent (Symbol comparison for dependent value should be case-independent #369)

This discussion was created from the release Release 0.4.3: Graphics / plotting stabilization.

[c3d]

This is the first release with binaries that are supposed to work on DM32. Use DB50X files for the DM32, DB48X files for the DM42.

[c3d]

Due to other commitments, expect development of DB48X to slow down for two weeks.
